Stonehenge archaeologists reveal new theory of why monument was built

Stonehenge may have been built on a site occupied by hunters for?roughly?5,000 prior to its construction.

A site near Stonehenge has revealed archaeological evidence that hunters lived just a mile from Stonehenge roughly 5,000 years prior to the construction of the first stones, new research suggests.

What's more, the site, which was occupied continuously for 3,000 years, had evidence of burning, thousands of flint tool fragments and bones of?wild aurochs?, a type of extinct giant cow. That suggests the area near Stonehenge may have been an auroch migration route that became an ancient feasting site, drawing people together from across different cultures in the region, wrote lead researcher David Jacques of the Open University in the United Kingdeom, in an email.

"We may have found the cradle of?Stonehenge, the reason why it is where it is," Jacques wrote. [In Photos: A Walk Through Stonehenge]

The new discovery may also identify the people who first erected structures at Stonehenge. A few gigantic pine posts, possibly totem poles, were raised at Stonehenge between 8,500 and 10,000 years ago, but until now there was scant evidence of occupation in the area that long ago. The new research suggests those ancient structures may perhaps have been raised to honor a sacred hunting ground.

Mysterious monument

For decades, people have wondered at the enigmatic stone structures erected roughly 5,000 years ago in the plains of Wiltshire, England. No one knows why ancient people built the structure: some believe it was a place of ancient worship or a sun calendar, whereas still others think it was a symbol of unity or even that?Stonehenge was inspired by a sound illusion.

The large megaliths, known as sarsens, are up to 30 feet tall and weigh up to 25 tons, while the smaller bluestones weigh up to 4 tons. Researchers think the?giant boulders?came from a quarry near Marlborough Downs, just 20 miles (32 kilometers) from the iconic site, while the bluestones likely came from Preseli Hills in Wales, nearly 156 miles (250 km) away from Stonehenge.

Old photographs

Jacques was looking through archival photographs of the region surrounding Stonehenge when he spotted a site known as Vespasian's Camp, just a mile from Stonehenge in nearby Amesbury.

Realizing that it hadn't been fully surveyed, Jacques began to investigate the area, which harbored a freshwater spring.

Because animals like to stop and drink at such watering holes, Jacques wondered whether ancient man may have settled nearby as well.

The team uncovered roughly 350 animal bones and 12,500 flint tools or fragments, as well as lots of evidence of burning. Carbon dating suggested the area was occupied by humans from 7500 B.C. to 4700 B.C. ? roughly 5,000 years prior to the erection of the?first stones at Stonehenge. [See Photos of the Stonehenge Hunting Ground?]

"The spring may have originally attracted large animals to it, which would have aided hunting and may have led to associations that the area was a sacred hunting ground," Jacques wrote.

In addition, the researchers found tools made from stone from one region of England, but fashioned in the style of another region (for instance, a?stone tool?made from Welsh or Cornwall slate, but made in a style typical of Sussex). That suggests the people from different regions were coming together at the site, Jacques wrote.

Ancient builders?

The findings could help researchers pinpoint why the ancient builders of Stonehenge chose the place they did, Jacques said.?

"We have found a bridge from which transmission of cultural memory about the 'specialness' of the place where the stones were later being put up was possible," Jacques wrote. "We are getting closer to understanding their reasons for putting it up ? it is all to do with ancestors, but those ancestors go much further back than has previously been realised."

The findings show "there was a substantial interest in the Stonehenge landscape well before the stones were hauled there and erected," said Timothy Darvill, an archaeologist at Bournemouth University in the U.K., who was not involved in the study.

Excavations dating to 2008 at Stonehenge also confirm earlier use at the?megalithic site, Darvill wrote. However, what makes the Amesbury discovery special is the large trove of auroch bones found in the area, which suggests the spring was on a natural migration route for the wild aurochs, he said.

A program about the Amesbury site will air on BBC 4 on April 29.

Google Glass easter egg reveals the team that built it

DNP Glass Egg

Google has a long history of doling out easter eggs to amuse and delight the public, so naturally it decided to sneak one in the Explorer Edition of Glass as well. New Glass Explorer Jay Lee discovered that when you select View Licenses under Settings and Device Info, then tap the touchpad nine times (an audible beep increasing in pitch will follow each tap), you'll be able to see the entire Project Glass team in a panoramic shot. Mike LeBeau from the Glass team confirmed that he snuck that easter egg in to pay tribute to his colleagues. Naturally, now we can't help but wonder if shaking your head in tune to the Konami Code (sans A and B button-pushing) will uncover more hidden gems.

(AP) ? Amid the celebration surrounding the opening of son George W. Bush's presidential library, former first lady Barbara Bush is brushing aside talk of a Jeb Bush run for the White House.

Appearing in an interview Thursday on NBC's "Today" show, Mrs. Bush was asked how she felt about Jeb, the former governor of Florida, seeking the presidency in 2016.

Mrs. Bush replied, quote, "We've had enough Bushes."

She went on to say she thought there were many worthy candidates, telling anchor Matt Lauer, "There are people out there" who are qualified. Mrs. Bush, who had a reputation for bluntness when her husband George H.W. Bush was president, spoke from the site of the presidential library. On Wednesday, George W. Bush told CNN he thought Jeb Bush should run for president.

Lawmakers ask who knew what about bomb suspect

BOSTON (AP) ? Lawmakers are asking tough questions about how the government tracked suspected Boston Marathon bomber Tamerlan Tsarnaev when he traveled to Russia last year, renewing criticism from after the Sept. 11 attacks that failure to share intelligence may have contributed to last week's deadly assault.

Following a closed-door briefing on Capitol Hill with the FBI and other law enforcement officials on Tuesday, Sen. Saxby Chambliss, R-Ga., vice chairman of the Senate Intelligence Committee, said it doesn't appear yet that anyone "dropped the ball." But he said he was asking all the federal agencies for more information about who knew what about the suspect.

"There still seem to be serious problems with sharing information, including critical investigative information ... not only among agencies but also within the same agency in one case," said committee member Sen. Susan Collins, R-Maine.

Lawmakers intensified their scrutiny as funerals were held Tuesday for an 8-year-old boy killed in the bombings and a campus police officer who authorities said was shot by Tsarnaev and his younger brother days later. A memorial service for the officer, 26-year-old Sean Collier, is scheduled for Wednesday. Vice President Joe Biden is expected to speak.

Also Wednesday, Boylston Street, where the blasts occurred, reopened to the public after being closed since the bombings.

While family said that the older Tsarnaev had been influenced by a Muslim convert to follow a strict type of Islam, brother 19-year-old Dzhokhar Tsarnaev remained hospitalized after days of questioning over his role in the attacks. Tamerlan Tsarnaev, 26, was killed in a shootout with police last week.

Conflicting stories appeared to emerge about which agencies knew about Tamerlan Tsarnaev's six-month trip to Russia last year how they handled it. Homeland Security Secretary Janet Napolitano told the Senate Judiciary Committee on immigration legislation that her agency knew about Tsarnaev's journey to his homeland.

But Sen. Lindsey Graham, R-S.C., said the FBI "told me they had no knowledge of him leaving or coming back."

Information-sharing failures between agencies prompted an overhaul of the U.S. intelligence system after the Sept. 11, 2001, terror attacks.

Meanwhile, evidence mounted that Tsarnaev had embraced a radical, anti-American strain of Islam. Family members blamed the influence of a Muslim convert, known only to the family as Misha, for steering him toward a strict type of Islam.

"Somehow, he just took his brain," said Tamerlan's uncle, Ruslan Tsarni of Montgomery Village, Md., who recalled conversations with Tamerlan's worried father about Misha's influence.

Authorities don't believe Tsarnaev or his brother had links to terror groups. However, two U.S. officials said that Tsarnaev frequently looked at extremist websites, including Inspire magazine, an English-language online publication produced by al-Qaida's Yemen affiliate. The magazine has endorsed lone-wolf terror attacks.

Both officials spoke on condition of anonymity because they were not authorized to discuss the investigation publicly.

Eight-year-old Martin Richard, a Boston schoolboy and the youngest of those killed by the blasts, was laid to rest Tuesday after a family-only funeral Mass.

"The outpouring of love and support over the last week has been tremendous," the family said in a statement. "This has been the most difficult week of our lives."

The Richards family said they would hold a public memorial service for Martin in the coming weeks.

Dzhokhar Tsarnaev's condition was upgraded from serious to fair Tuesday as investigators continued building their case against him.

He could face the death penalty after being charged Monday with joining forces with his brother in setting off shrapnel-packed pressure-cooker bombs. Three people were killed and over 260 injured. About 50 were still hospitalized.

Dzhokhar Tsarnaev was captured hiding in a tarp-covered boat in a suburban Boston backyard on Friday.

In Washington, Senate Intelligence Committee member Richard Burr, R-N.C., said after his panel was briefed by federal law enforcement officials that there is "no question" that Tamerlan Tsarnaev was "the dominant force" behind the attacks and that the brothers had apparently been radicalized by material on the Internet rather than by contact with militant groups overseas.

The brothers' parents are from Dagestan, a predominantly Muslim province in Russia's Caucasus, where Islamic militants have waged an insurgency against Russia. A U.S. Embassy official said Wednesday that a team of U.S. investigators has traveled to Dagestan to speak to the parents. The official spoke on condition of anonymity because he was not authorized to speak to the media.

Family members reached in the U.S. and abroad by The Associated Press said Tamerlan was influenced by Misha.

After befriending Misha, Tamerlan gave up boxing, stopped studying music and began opposing the wars in Afghanistan and Iraq, according to family members, who said he turned to websites and literature claiming that the CIA was behind 9/11.

"You could always hear his younger brother and sisters say, 'Tamerlan said this,' and 'Tamerlan said that.' Dzhokhar loved him. He would do whatever Tamerlan would say," recalled Elmirza Khozhugov, the ex-husband of Tamerlan's sister. He spoke by telephone from his home in Almaty, Kazakhstan.

The brothers, who came to the U.S. from Russia a decade ago, were raised in a home that followed Sunni Islam, the religion's largest sect, but were not regulars at the mosque and rarely discussed religion, Khozhugov said.

Then, in 2008 or 2009, Tamerlan met Misha, a heavyset bald man with a reddish beard. Khozhugov didn't know where they met but believed they attended a Boston-area mosque together.

Napolitano said Tuesday that her agency knew of Tamerlan Tsarnaev's trip to Russia. She said that even though the suspect's name was misspelled on a travel document, redundancies in the system allowed his departure to be captured by U.S. authorities in January 2012.

Meanwhile, a U.S. Embassy official said U.S. investigators traveled to southern Russia to speak to the brothers' parents, hoping to learn more about their motives.

In other developments:

? A lawyer for Tamerlan Tsarnaev's wife, Katherine Tsarnaeva, said his client "is doing everything she can to assist with the investigation," although he would not say whether she had spoken with federal authorities. Another lawyer for Tsarnaeva said the 24-year-old deeply mourned the loss of innocent victims in the bombings.

? The Massachusetts state House turned aside a bid by several lawmakers to reinstate the death penalty in certain cases, including the murder of police officers. In a 119-38 vote, the House sent the proposal to a study committee rather than advance it to an up-or-down vote.

? In New Jersey, the sisters of the suspects, Ailina and Bella Tsarnaeva, issued a statement saying they were saddened to "see so many innocent people hurt after such a callous act." Later, in brief remarks to several news outlets, Ailina described her elder brother as a "kind and loving man." She said of both brothers: "I have no idea what got into them" and also that "at the end of the day no one knows the truth."

? Phantom Fireworks of Seabrook, N.H., said Tamerlan Tsarnaev bought 48 mortar shells at the store in February. Company Vice President William Weimer, however, said the amount of gunpowder that could be extracted from the fireworks would not have been enough for the Boston bombs.

? A fund created to benefit the victims of the Boston Marathon attacks has generated $20 million. Mayor Thomas Menino said more than 50,000 donors from across the world have made donations to One Fund Boston.

Nintendo has another tough year, sells just 390,000 Wii Us in the last quarter

Nintendo announces another testing quarter, sells another 390,000 Wii Us

While there's no shortage of 3DS iterations headed to the market, Nintendo is having a harder time selling its new Wii U. Profits for the year are also half of its own predictions, despite the fact that Nintendo reduced its rosy estimates in the interim. Net sales are down 1.9 percent over the last year, down to 635 billion yen, but most importantly the company has managed to turn its net income into positive figures, netting 7 billion yen over the last year, compared to a 40 billion yen loss the year before. Following its initial launch, Wii U sales have slowed substantially, with only 390,000 units sold since December (now totaling 3.45 million), while the 3DS continues to sell in healthier numbers, with Nintendo shifting 1.25 million handhelds in the same period.

Focusing on the next year, the company maintains that it'll increase net income to 10 billion yen in the next twelve months, with a focus on selling "the compelling nature" of its gaming hardware, as well as pushing its 3DS more in foreign markets. The financial statement adds that the games maker plans to concentrate on "proactively releasing key Nintendo titles" starting the second half of this year "in order to regain momentum." Those key titles will have to hit hard, as certain competitors' new consoles are creeping closer.

Insurance Job Interview Tips: What To Expect, How To Prepare And ...

Think you can just wing it during your next job interview? Think again.

If you really want to impress an insurance employer in a job interview, it all comes down to one thing: always be prepared.

One of the biggest mistakes students and recent graduates make is coming in unprepared, says?Trevor Buttrum, Career Connections?Program Manager at the Insurance Institute of Canada.

Being unfamiliar with the company, being unable to make connections or draw parallels between your experience and the role, or showing up late are the three biggest insurance industry job interview don?ts, he adds.

Keep reading to find out what to expect during, how to prepare for and how to follow up after your next job interview with an insurance employer:

What to expect

Most interviews for insurance jobs involve a two-step process:

The telephone screen

The process may start with a telephone screen conducted by a recruiter in the company?s human resources department. ?The telephone screen is designed to confirm that you meet the criteria for the position, establish your understanding of the role, and get a sense of your style or approach,? Trevor explains.

The in-person interview

If you meet the requirements of the telephone screen, it will usually be followed by one or two in-person interviews that may now include the hiring manager and other colleagues involved in the process. ?Don?t let it throw you if it is a panel interviewing you ? these are now common place!?

The in-person interviews will most likely be behavioural or competency-based, says Trevor. ?Think, ?Tell me about a time when?? or scenarios that get at how you might handle various aspects of the job.? The employer is looking for you to make connections between what you have done and how it will help you to be successful in your potential new role.?

Kick it up a notch:?One way you can seriously stand out from other candidates is by sending thank you notes to the people you met with after each stage of the process, timed so they arrive during the day after your interview. ?The thank you note provides a chance for you to summarize your conversation, maybe touch on something you wish you had and reiterate your interest in the position,? Trevor explains.

How to prepare

Find out what you?ll need

When you?re invited for the interview, whether it?s by phone or email, always ask if there?s anything that you should bring. Here?s why:

?I once had an employer say, ?Good thing you asked, I almost forgot to mention that we would like to see an example of a presentation you have developed. ?Could you supply us with a version on a USB key??? Trevor recalls. ?I would have never just ?had one on hand? in an interview.?

Always bring:

  • Printed copies of your resume, both for your reference and in case they don?t have one
  • A notebook and pen so you can take notes
  • Your references, printed on a single sheet, in case the employer would like to review or contact them following your interview

Know yourself

In a job interview situation, knowing exactly how your education and experience will benefit the employer and the role you?ve applied for is half the battle.

Ideally, you?ve already determined this in order to tailor your resume and apply for the job in the first place, but if not, learn as much as you can about the role and map out how you fit the bill, Trevor says.

?Check out the??Your Experience? page?in the post-secondary section of the?Career Connections website,? he advises. ??Identifying these specific examples will help you weave them into your answers to the interviewer?s questions.?

Kick it up a notch:?Practice your answers to typical job interview questions with a trusted friend or career counsellor and introduce examples from your experience into the conversation. Trevor recommends using the STAR method to help you answer the interviewer?s questions:

  • Situation ? Setting the stage: Who, when, where, why? (5% of your answer)
  • Task ? What did you do? What was your role? (5%?of your answer)
  • Action ? How did you do it? What steps did you take? (70%?of your answer)
  • Result ? What happened?? What was the outcome (20%?of your answer)

Do your research

How much do you know about the company, its business, core values (and how they align to your own) and any other unique aspects to it?

?Web research, reading trade publications, checking out examples of their consumer marketing, and talking to industry professionals are great ways to gain these types of insights,? he explains.

?This information enables you to further tailor your answers to the employer?s questions and might help you develop some of your own.?

Kick it up a notch:?Trevor recommends paying close attention to employers? charity and community service activities, specialty in the insurance sector, and whether or not the company was ranked on any top employer lists.

Dress for success

?Insurance is a traditional industry and, although business casual is becoming the norm for day-to-day in the workplace, it is suggested that you go business formal for the interview,? Trevor advises.

What does that mean? ?Suit jackets, blazers, pressed pants, blouses, collared shirts, ties, nicely-shined shoes and knee-length skirts are what come to mind,? he adds.

How to follow up

Should you or shouldn?t you? When and how often? These are all questions that tend to plague students and recent graduates following their job interviews.

?Before you leave the interview, ask what the next steps are in the process and when the employer anticipates moving forward in their decision making,? Trevor recommends. ?Keep this date in mind and use it as a temperature gauge for when to follow-up next.?

From there, don?t push too hard. ?Like any relationship, high frequency or intensity follow-up can send the wrong message,? he says, adding that the process may be taking slightly longer than expected, hiring may not be the person?s primary responsibility and other priorities may have arisen since your interview. ?Be sure to give the employer a little leeway.?

For example, if they said they would make a decision by Friday, consider following up on the Tuesday if you haven?t heard from them.

Kick it up a notch:?Frame your follow-up as checking in to see where they are in the process rather than asking whether or not they have reached a decision, and let the employer know you are happy to answer any questions or provide additional information which might support the process, Trevor advises.

New solar-cell coating could boost efficiency

Friday, April 19, 2013

Throughout decades of research on solar cells, one formula has been considered an absolute limit to the efficiency of such devices in converting sunlight into electricity: Called the Shockley-Queisser efficiency limit, it posits that the ultimate conversion efficiency can never exceed 34 percent for a single optimized semiconductor junction.

Now, researchers at MIT have shown that there is a way to blow past that limit as easily as today's jet fighters zoom through the sound barrier ? which was also once seen as an ultimate limit.

Their work appears this week in a report in the journal Science, co-authored by graduate students including Daniel Congreve, Nicholas Thompson, Eric Hontz and Shane Yost, alumna Jiye Lee '12, and professors Marc Baldo and Troy Van Voorhis.

The principle behind the barrier-busting technique has been known theoretically since the 1960s, says Baldo, a professor of electrical engineering at MIT. But it was a somewhat obscure idea that nobody had succeeded in putting into practice. The MIT team was able, for the first time, to perform a successful "proof of principle" of the idea, which is known as singlet exciton fission. (An exciton is the excited state of a molecule after absorbing energy from a photon.)

In a standard photovoltaic (PV) cell, each photon knocks loose exactly one electron inside the PV material. That loose electron then can be harnessed through wires to provide an electrical current.

But in the new technique, each photon can instead knock two electrons loose. This makes the process much more efficient: In a standard cell, any excess energy carried by a photon is wasted as heat, whereas in the new system the extra energy goes into producing two electrons instead of one.

While others have previously "split" a photon's energy, they have done so using ultraviolet light, a relatively minor component of sunlight at Earth's surface. The new work represents the first time this feat has been accomplished with visible light, laying a pathway for practical applications in solar PV panels.

This was accomplished using an organic compound called pentacene in an organic solar cell. While that material's ability to produce two excitons from one photon had been known, nobody had previously been able to incorporate it within a PV device that generated more than one electron per photon.

"Our whole project was directed at showing that this splitting process was effective," says Baldo, who is also the director of the Center for Excitonics, sponsored by the U.S. Department of Energy. "We showed that we could get through that barrier."

The theoretical basis for this work was laid long ago, says Congreve, but nobody had been able to realize it in a real, functioning system. "In this system," he says, "everyone knew you could, they were just waiting for someone to do it."

Since this was just a first proof of principle, the team has not yet optimized the energy-conversion efficiency of the system, which remains less than 2 percent. But ratcheting up that efficiency through further optimization should be a straightforward process, the researchers say. "There appears to be no fundamental barrier," Thompson says.

While today's commercial solar panels typically have an efficiency of at most 25 percent, a silicon solar cell harnessing singlet fission should make it feasible to achieve efficiency of more than 30 percent, Baldo says ? a huge leap in a field typically marked by slow, incremental progress. In solar cell research, he notes, people are striving "for an increase of a tenth of a percent."

Solar panel efficiencies can also be improved by stacking different solar cells together, but combining solar cells is expensive with conventional solar-cell materials. The new technology instead promises to work as an inexpensive coating on solar cells.

The work made use of a known material, but the team is now exploring new materials that might perform the same trick even better. "The field is working on materials that were chanced upon," Baldo says ? but now that the principles are better understood, researchers can begin exploring possible alternatives in a more systematic way.

Researchers discover that stem cell senescence drives aging

Friday, April 19, 2013

Declining levels of the protein BubR1 occur when both people and animals age, and contribute to cell senescence or deterioration, weight loss, muscle wasting and cataracts. Mayo Clinic researchers have shown that adult progenitor or stem cells -- important for repair and regeneration of skeletal muscle and maintenance of healthy fat tissue -- are subject to cellular senescence, and that clearance of these cells limits age-related deterioration of these tissues. The findings appear today online in the journal Cell Reports.

BubR1 is an essential part of the mitotic checkpoint, the mechanism controlling proper cell division or mitosis. Without sufficient levels of BubR1, chromosomal imbalance will occur, leading to premature aging and cancer. Using mutant mice that expressed low levels of BubR1, the researchers found development of dysfunctional tissue with impaired cell regeneration. In analyzing the progenitor populations in skeletal muscle and fat, they found that a subset of progenitors was senescent and that the tumor suppressor p53 was acting to prevent this from happening through activation of p21.

"Earlier we discovered that senescent cells accumulate in tissues with aging and that removal of these cells delays age-related functional decline in these tissues," says Jan van Deursen, Ph.D., a Mayo Clinic molecular biologist and senior author of the study. "The key advance of the current study is that the progenitor cell populations are most sensitive for senescence, thereby interfering with the innate capacity of the tissue to counteract degeneration."

Not only do the findings contribute to knowledge on cell senescence as it relates to aging and related diseases, but understanding the mechanisms may lead to future therapies, say the researchers.

Reddit Photo Might Show Suspect 2 and Victim - Business Insider

This picture appears to show 8-year-old Martin Richard (circled in blue) next to his father, sister (green jacket), and older brother (leaning on the railing to the left).

A photo posted on reddit?shows Boston Marathon Bombing "Suspect 2" walking behind 8-year-old victim Martin Richard and his family, with what appears to be Suspect 2's backpack on the ground between them.

Another version of the photo focusing on what looks like Suspect 2 and his bag, but blurring out the crowd, was?previously aired by Fox 25 and other news outlets.

These photos are unconfirmed by police.

A long thread of analysis on Reddit suggests that?Martin's family are shown at the site of the second blast. (Martin's 7-year-old sister lost a leg in the blast while his mother?Denise suffered a serious brain injury.)

A?user?on reddit notes that?the picture shows the spot of the second bombing because the background shows the sign for the Atlantic Fish restaurant, which is?located?where police?place?the second blast.

Earlier the FBI?released images of two suspects?and asked for the public's help identifying them.?Reddit then?identified?the hat of Suspect 1 and potentially?found a hi-res picture?of Suspect 2.

The above photo, a snapshot of a moments before two pressure cooker bombs killed three people and wounded more than 180 on Monday, is heartbreaking.?

Here's a picture of Martin from earlier this month:

After major earthquake: A global murmur, then unusual silence

Apr. 19, 2013 ? In the global aftershock zone that followed the major April 2012 Indian Ocean earthquake, seismologists noticed an unusual pattern. The magnitude (M) 8.6 earthquake, a strike-slip event at intraoceanic tectonic plates, caused global seismic rates of M?4.5 to rise for several days, even at distances thousands of kilometers from the mainshock site. However, the rate of M?6.5 seismic activity subsequently dropped to zero for the next 95 days.

This period of quiet, without a large quake, has been a rare event in the past century. So why did this period of quiet occur?

In his research presentation, Fred Pollitz of the U.S. Geological Survey suggests that the Indian Ocean earthquake caused short-term dynamic stressing of a global faulting system. Across the planet, there are faults that are "close to failure" and ready to rupture. It may be, suggests Pollitz and his colleagues, that a large quake encourages short-term triggering of these close-to-failure faults but also relieves some of the stress that has built up along these faults. Large magnitude events would not occur until tectonic movement loads stress back on to the faults at the ready-to-fail levels they reached before the mainshock.

Using a statistical model of global seismicity, Pollitz and his colleagues show that a transient seismic perturbation of the size of the April 2012 global aftershock would inhibit rupture in 88 percent of their possible M?6.5 earthquake fault sources over the next 95 days, regardless of how close they were to failure beforehand.

The Sequester and the Military Budget

Project on Defense Alternatives
April 18, 2013

More than a month after the onset of sequestration, neither the White House nor Congress are any closer to enacting a ?grand bargain? that could replace the nine-year sequester in its entirety or a one-year ?patch? that could be used to offset the FY13 or FY14 sequesters.? In fact, the recently unveiled budget request for Fiscal Year 2014 all but ignored the automatic spending reductions that impact almost every sector of the federal government.? Veteran defense reporter John Bennettbelieves?that the recent budget request has but one purpose for the White House, and that is ?constructing the foundation for a ?grand bargain? fiscal deal with Senate Republicans.?? As a result, sequestration still seems here to stay for the immediate future.

This seeming lack of progress has prompted the chair of the Senate Armed Services Committee, Senator Carl Levin (D-MI), to?advocate for a one-year patch to avoid sequestration in Fiscal Year 2014.? Because both the White House and Congress are budgeting to pre-sequester levels, the military budget faces a more-than $50 billion cut in Fiscal Year 2014.? The FY13 sequester cuts are currently being implemented by the Office of Management and Budget.? If Congress decided to appropriate at the post-sequester spending levels in Fiscal Year 2014, it could avoid another sequester altogether.? Still, it appears as if Congress will continue to ignore sequestration as it drafts its FY14 spending bills.? While Levin remains hopeful that a ?grand bargain? will eventually be enacted, he believes that a one-year patch to avoid the automatic cuts in FY14 is essential.? Last year, Levin rejected similar temporary proposals from Republicans and instead advocated an annual military spending reduction of $10 billion per year for the next decade.

Appearing before the?House Appropriations subcommittee on defense?this week, Secretary of Defense Chuck Hagel announced that the Pentagon is preparing a largereprogramming request?to offset some of the budgetary disruption resulting from the onset of sequestration.? For example, the department is currently facing a $22 billion shortfall in operations and maintenance funding in Fiscal Year 2013.? During the hearing, Pentagon Comptroller Robert Hale noted that the department is planning on reducing its civilian workforce by five to six percent between now and Fiscal Year 2018 in order to keep pace with active duty reductions.? Furthermore, Hale asserted that civilian workforce reductions will need to be coupled with infrastructure downsizing through the Base Realignment and Consolidation (BRAC) process.? The Pentagon?says?that their latest BRAC proposal stems from a 2004 study in which the department found it had 24 percent excess domestic infrastructure. ?Still, Chairman Levin?threw cold water on the proposal, saying he doesn?t think the Senate will be any more receptive to domestic base closures this year than it was last year.

In its recent budget submission, the Army confirmed that the development phase of the new Ground Combat Vehicle program will be delayed by one year.? This delay follows a scathing Congressional Budget Office report that found alternative options to the GCV would be both more capable and less costly than current plans.? The new chair of the House Armed Services subcommittee on tactical air and land forces, Representative Michael Turner (R-OH),?recently told reportersthat he?s keeping a close watch on the Army?s acquisition budget, and especially the Ground Combat Vehicle, to make sure that another F-35-like boondoggle doesn?t emerge.

Last month, Representative Ron Kind (D-WI) introduced?H.R. 1361, the Inefficient Defense Elimination Act of 2013, which would require the Pentagon to follow through on program terminations and the retirement of certain military assets that were included in last year?s budget.? This includes cancellation of the Global Hawk Block 30 drone program, the mothballing of the C-27J Spartan transport aircraft, and the early retirement of seven aging cruisers and two amphibious landing ships.? The Pentagon has included many of the aforementioned recommendations in this year?s budget.? Meanwhile, Senator Jeanne Shaheen (D-NH) has introduced?S. 664, the Government Contractor Accountability Act of 2013, which would require federal agencies to enact the recommendations of Inspectors General with respect to contractor savings and reforms.? ?My bill would ensure [Inspector General] recommendations for cutting costs and rooting out fraud and abuse are given sufficient consideration by the federal agencies,? Shaheen said in a?statement.

Yesterday, Representative Mike Coffman (R-CO) sent a letter to House Appropriations Committee leaders requesting decreased funding for ten military programs as appropriators begin drafting FY14 spending bills.? Among the items recommended for decreased funding, many of which are included in Coffman?s?Smarter Than Sequester Defense Spending Reduction Act, are the Army?s Ground Combat Vehicle, refurbishments for M1 Abrams tanks, military bands, and active duty Marine Corps and Army personnel.? Coffman wrote, ?Our current fiscal situation requires us to identify spending reductions throughout the budget, including the defense budget.? However, we should do so in a responsible manner, with targeted reductions in less critically important areas.?

As early as?this summer, F/A-18 manufacturer?Boeing will introduce an upgraded version of the Super Hornet, which the contractor hopes will be considered as a cheaper alternative to Lockheed Martin?s F-35 Lightning II. The Navy currently plans to buy 260 units of the F-35C variant, a number at risk of being supplanted by the less expensive Super Hornets. Meanwhile, both USMC Commandant Gen. James Amos and Chief of Naval Operations Adm. Jonathan Greenert have reaffirmed their support for the F-35, though both parties acknowledge procurement is moving slowly: Gen. Amos?referred?to the procurement process as ?constipated.? Gen. Amos and Adm. Greenert criticized the increased role of Pentagon program managers and blamed them for clogging procurement reform.? Meanwhile, the Marine Corps recently?announced?that its variant of the F-35 should be ready for initial operations as soon as July 2015.

A yearlong Senate Armed Services Committee?review?has found that the United States spends more than $10 billion annually to maintain overseas bases in allied countries. Of this total, over seventy percent is distributed to Germany, Japan, and South Korea; where spending is $4 billion, $2 billion and $1.1 billion respectively. Compounding expenses, co-payments by the host countries are often accepted as ?in-kind? payments of services or facilities instead of cash.? Not only have allied payments failed to ?keep up with rapidly rising U.S. costs,? the report notes, but there is scant congressional or Pentagon oversight of the construction projects.

Global military spending dropped in 2012 for the first time since 1998. ?According to a?report?prepared by the Stockholm International Peace Research Institute (SIPRI), the international community spent $1.75 trillion on its military, down 0.5 percent from the year before.? Defense outlays shrank in the West, but rose in?Russia, China, and the Middle East.? The United States retained the highest percentage at 39 percent of all military spending.? SIPRI experts noted that while Chinese military spending has increased over the past year, it has not seen a commensurate improvement in military capability.

Small in size, big on power: New microbatteries the most powerful yet

Small in size, big on power: New microbatteries the most powerful yet [ Back to EurekAlert! ] Public release date: 16-Apr-2013

CHAMPAIGN, Ill. Though they be but little, they are fierce. The most powerful batteries on the planet are only a few millimeters in size, yet they pack such a punch that a driver could use a cellphone powered by these batteries to jump-start a dead car battery and then recharge the phone in the blink of an eye.

Developed by researchers at the University of Illinois at Urbana-Champaign, the new microbatteries out-power even the best supercapacitors and could drive new applications in radio communications and compact electronics.

Led by William P. King, the Bliss Professor of mechanical science and engineering, the researchers published their results in the April 16 issue of Nature Communications.

"This is a whole new way to think about batteries," King said. "A battery can deliver far more power than anybody ever thought. In recent decades, electronics have gotten small. The thinking parts of computers have gotten small. And the battery has lagged far behind. This is a microtechnology that could change all of that. Now the power source is as high-performance as the rest of it."

With currently available power sources, users have had to choose between power and energy. For applications that need a lot of power, like broadcasting a radio signal over a long distance, capacitors can release energy very quickly but can only store a small amount. For applications that need a lot of energy, like playing a radio for a long time, fuel cells and batteries can hold a lot of energy but release it or recharge slowly.

"There's a sacrifice," said James Pikul, a graduate student and first author of the paper. "If you want high energy you can't get high power; if you want high power it's very difficult to get high energy. But for very interesting applications, especially modern applications, you really need both. That's what our batteries are starting to do. We're really pushing into an area in the energy storage design space that is not currently available with technologies today."

The new microbatteries offer both power and energy, and by tweaking the structure a bit, the researchers can tune them over a wide range on the power-versus-energy scale.

The batteries owe their high performance to their internal three-dimensional microstructure. Batteries have two key components: the anode (minus side) and cathode (plus side). Building on a novel fast-charging cathode design by materials science and engineering professor Paul Braun's group, King and Pikul developed a matching anode and then developed a new way to integrate the two components at the microscale to make a complete battery with superior performance.

With so much power, the batteries could enable sensors or radio signals that broadcast 30 times farther, or devices 30 times smaller. The batteries are rechargeable and can charge 1,000 times faster than competing technologies imagine juicing up a credit-card-thin phone in less than a second. In addition to consumer electronics, medical devices, lasers, sensors and other applications could see leaps forward in technology with such power sources available.

"Any kind of electronic device is limited by the size of the battery until now," King said. "Consider personal medical devices and implants, where the battery is an enormous brick, and it's connected to itty-bitty electronics and tiny wires. Now the battery is also tiny."

Now, the researchers are working on integrating their batteries with other electronics components, as well as manufacturability at low cost.

"Now we can think outside of the box," Pikul said. "It's a new enabling technology. It's not a progressive improvement over previous technologies; it breaks the normal paradigms of energy sources. It's allowing us to do different, new things."

A Tax Day Story For Hard-Cider Lovers

Doc's Draft hard cider, bottled in Warwick, N.Y., stands to benefit from new regulations proposed by Sen. Chuck Schumer, D-N.Y.

Doc's Draft hard cider, bottled in Warwick, N.Y., stands to benefit from new regulations proposed by Sen. Chuck Schumer, D-N.Y.

Susie Wyshak/via Flickr

Is small-batch hard apple cider the next microbrew? It seems everybody and their brother is experimenting with ways to make the potent stuff profitable. Sales of domestically produced hard cider have more than tripled since 2007, according to beverage industry analysts ? and that's not counting Europe, where it has held a steady popularity for centuries.

But there's a bit of a hitch that may stunt cider's future growth. Apple blight? Climate change? Finicky millennial tastes? Well, maybe, but Sen. Charles Schumer, D-N.Y., is focusing on the antiquated way the products are taxed.

Schumer, the man who never misses the chance to promote his state's agriculture (have you seen the video of him "cooking" for the presidential inaugural ceremonies?), is proposing legislation he says will supercharge the cider boom for both the Empire State and the whole country.

"New York is the second-largest apple producer in the country, and there's no doubt it should be at the core of the hard-cider industry, which is rapidly growing in popularity," says Schumer. "However, current federal tax rules make it extremely costly for Capital Region producers and consumers alike to produce, market and sell this product, which could prevent New York's hundreds of apple growers and hard cider producers from fully benefiting from the stable income that comes with this new product."

Here's the problem, as Schumer sees it: Under federal law, hard apple and pear ciders cannot exceed 7 percent alcohol by volume ? or they become subject to the higher taxes of products with higher alcohol levels, like wine.

But hitting the right level and no higher is tricky when working with a product like apples, which naturally vary in sweetness levels. Since the amount of sugar varies, that means the amount of alcohol produced will ultimately vary, too. Sometimes, those variations can put a particular cider batch's alcohol content above that 7 percent mark.

And there are other factors that can alter how boozy a cider batch is.

"We don't know for sure how efficiently the available sugars will or will not be converted to ethanol," says Chris Gerling of the Cornell Extension Enology Lab. (It's about 51 percent, but not always.)

Gerling has worked with wine and hard-cider producers in New York state for years on ways to boost production, teaching classes and offering advice. But recently, he's become the student, learning a bit of excise tax law, courtesy of the Alcohol and Tobacco Tax and Trade Bureau, as this issue has come up.

"The problem is that cider has to kind of drift between beer and wine in the regulations, and can cross major TTB definition [and/or] tax boundaries with relatively small changes [and/or] fermentation outcomes," Gerling says.

And it gets even more complicated.

Add too much carbonation to the hard cider, and it falls into the even higher tax realm of champagne.

"It's much more of a burden for cider producers than for somebody who's selling sparkling wine for $50 a bottle," he says.

One reason regulations may be outdated is that hard apple cider, formerly the drink of choice for Colonial Americans, fell out of favor once beer got big. People just stopped making it here. It's only in recent years, as more U.S. producers have taken up making cider, that the tax issue has become a growing problem.

The tax issue as it stands now creates all kind of messy labeling issues and potentially confusing price changes for cider makers, Schumer says, and can be an impediment to getting the stuff to market. That's especially true, he says, for the increasing number of small craft brewers and orchards with bushels of imperfect apples looking to turn more fruit into reliable profits, and those looking to plant new cider-specific varieties.

The CIDER Act (yes, members of Congress love acronyms) would change the law to give cider makers up to 8.5 percent alcohol by volume to work with ? a range similar to what winemakers enjoy ? and bring U.S law in line with the European Union, where hard cider never lost its appeal.

So what would it mean to the U.S. consumer? A few more sweet hard-cider choices.

Identical Triplet Boys Shine In Top Cuba Ballet School (PHOTOS)

HAVANA -- Visitors to the elite feeder school for Cuba's renowned National Ballet might be forgiven for thinking they're suddenly seeing triple.

Identical triplets Angel, Cesar and Marcos Ramirez wear matching black leotards and white socks as they leap, prance and twirl across the linoleum floor of the mirrored studio. They share the same wiry build, olive complexion, mussed hairstyles and coffee-colored eyes. And they speak the same fast-paced Spanish in the high-pitched voice of children.

Even their instructors have trouble telling the Ramirez boys apart, but they say the 13-year-olds have already separated themselves from their peers technically and artistically, and all three have the talent to make a big splash in the ballet world when they grow up.

If they succeed, they will join a long line of celebrated dancers trained in Cuba, where fans from every social stratum follow the careers of ballet stars like Carlos Acosta and Rolando Sarabia as closely as those of baseball players or boxers.

"I want to be a dancer. The National Ballet of Cuba turns out great male dancers," said Marcos, sweat dripping from his face after a recent workout in the steamy studio as his brothers nodded in agreement. "And go on tour in many countries and travel the world by dancing."

Toward that end, the Ramirez brothers spend 12 hours a day at the National School of Ballet, housed in a graceful, cream-porticoed building that occupies a full half-block in colonial Old Havana. Classes include not only dance, but more mundane subjects like language, math and history.

A former social club with broad hallways and a majestic marble staircase, this is where the creme de la creme of young dancers from across the country train for a shot at stardom.

The school was founded seven decades ago by famed prima ballerina assoluta Alicia Alonso, now age 92, who is probably the most recognized person in Cuba not named "Castro."

"This school means a lot to us," Angel said. "It gives us the training to graduate as ballet dancers, which is the thing we want most."

While the odds are tough, Mirlen Rodriguez, a 24-year-old teacher and former student at the school, says the brothers all have a chance of making their careers onstage.

"They are at a level that is beyond high," Rodriguez said.

The three have already beaten long odds simply by being born.

According to 2010 data compiled by the U.S. National Center for Health Statistics, only 0.14 percent of births that year were triplets or higher-order multiple births.

Naturally born identical triplets, involving a single egg separating into three fetuses rather than multiple eggs being fertilized, are much rarer.

Mothers of Supertwins, a U.S. nonprofit group that provides support, education and research on higher-order multiple births, says about one of every 62,500 pregnancies results in identical triplets ? or 0.0016 percent.

The Ramirezes, born into a family that lives in the gritty neighborhood of Center Havana, say they are extremely close.

In conversation they often finish each other's thoughts. They also seem to have fun with their uniqueness, introducing themselves to a reporter as if their relationship wasn't apparent.

"My name is Angel Jesus Ramirez Castellanos, and I'm 13 years old," the first said with a sly smile, followed in turn by the others:

"My name is Marcos Abraham Ramirez Castellanos, and I'm 13 years old."

"My name is Cesar Josue Ramirez Castellanos, and I'm 13 years old."

While some identical siblings find it difficult to carve out their own identities, the Ramirezes say they relish their tripleness.

"For me it's a real stroke of luck being a triplet, being able to count on my brothers," Cesar said. "The disadvantage is that sometimes they scold you or correct you for something that another one did."

Instructors rely on tricks to tell them apart.

"There's one that has a little mark above the eyebrow. Another one gets dimples when he laughs," Rodriguez said.

"Then there's another that doesn't have dimples or a mole. During exams you have to put one of them there, another one here, the other way over there, and they have to stay in that formation."

She added, however, that while the boys share the same DNA and have been trained by the same instructors, they have unique personalities that show up in their dance. One is more mischievous, another more serious, the third the most talkative.

"They have the same physical form, the same configuration of legs and arms, but in their minds, each one is unique," Rodriguez said.

The triplets say they fell in love with dance in 2007 when their mother took them to a performance of "The Nutcracker," which is put on every Christmas season and costs just pennies to attend.

All three said it never occurred to them to worry about being teased for taking up dance. Ballet is broadly popular in Cuba, and the idea of a man donning a leotard has remarkably little stigma attached to it for a society that in other ways retains some macho attitudes.

The Ramirezes enrolled in the ballet school at age 10 after passing a rigorous exam and being selected over dozens of other children with similar dreams. More than 300 boys and girls train here in eight different grades, all hoping to make it to the National Ballet.

"It's a virus that can't be cured with antibiotics," said Ramona de Saa, the school's director. "And all that passion can be felt in the school."

The grueling day runs from 7 a.m. to 7 p.m. Mornings are devoted to traditional school subjects, while afternoons are for perfecting demi plies and barre work.

"One, two, three, four!" an instructor's voice called out during a recent rehearsal as the Ramirezes twirled around and around on tiptoe. "Again!"

"It's a career that requires a lot of sacrifice. It takes away much of your childhood," Rodriguez said. "While others maybe are at home watching cartoon movies, they have to be at rehearsal."
