Indiana Senate backs requiring ultrasound for "abortion pill" use
INDIANAPOLIS (Reuters) - The Indiana state Senate on Tuesday approved Republican-backed legislation to require women seeking to end pregnancies through use of the so-called abortion pill to have an ultrasound examination.
If it becomes law, the proposal would make Indiana the ninth state to require an ultrasound prior to an abortion, according to the Guttmacher Institute, a research group that supports abortion rights.
Senators voted 33 to 16 to approve the measure, advancing it for consideration by the state House of Representatives, which like the Senate is controlled by a Republican super-majority.
Republican Governor Mike Pence, a former U.S. congressman who strongly opposes abortion and championed federal attempts to cut off funding for abortion provider Planned Parenthood, is expected to sign the bill into law if it reaches his desk.
The bill, as first introduced by Republican state Senator Travis Holdman, would have required two ultrasounds before a woman could obtain a prescription for the abortion pill, officially known as RU486. It was amended to allow the doctor providing the drug to decide if a second exam was needed.
"It is a matter of the mother's health," said Holdman. It is dangerous to administer RU486 in some cases, such as if the fertilized egg implants outside the womb of the woman.
The bill as passed also would require clinics where RU486 medication is dispensed to meet the same standards as a facility that performs surgical abortions, a provision opponents said could force an Indiana clinic to close.
The two-pill abortion medication called RU486 has been legally available in the United States since 2000. By 2008 it accounted for about one-fourth of U.S. abortions performed before nine weeks of gestation, according to the Guttmacher Institute.
As approved by the Food and Drug Administration, the two drugs - mifepristone and misoprostol - are dispensed by prescription directly from a physician. They are not available in pharmacies. The medication is generally prescribed for ending pregnancies of less than eight weeks.
Opponents of the bill said it would effectively require women seeking an RU486 prescription to undergo an invasive transvaginal ultrasound probe, because that is the only exam capable of providing the information mandated by the bill during early stages of pregnancy.
The bill language does not specify the type of ultrasound required, and Holdman said a normal ultrasound would suffice.
Planned Parenthood of Indiana President Betty Cockrum said the new licensing requirements could force a Lafayette, Indiana, clinic that provides non-surgical abortion services to close.
"It's politics, pure and simple," Cockrum said, adding that requiring the clinic to meet surgical standards would not improve patient safety.

Do you know who your police and crime ... - Worcester News
Do you know who your police and crime commissioner is?
4:39pm Monday 25th February 2013 in News By Tom Edwards
ALMOST 90 per cent of people cannot name their police and crime commissioner, according to a damning new survey today.
The 41 new commissioners are?paid up to ?100,000?a year to head up the police force.
Among their powers is hiring and firing the chief constable, setting the budget - ?200 million a year in West Mercia, deciding how much council tax each household should pay and making key decisions about policing strategy.
The commissioners were chosen during national elections in November, but turnout everywhere was low, including just 14 per cent across the West Mercia force area.
Now the Electoral Reform Society has produced a report claiming that the elections ?failed both candidates and voters alike?.
The society says lessons need to be learned from the record-low turnout, and labels it ?an exercise in how not to run an election?.
Their report says people were left in the dark about who they could vote for and that the winter timing of the poll discouraged participatIon.
In a survey, included in the report, 1,000 adults were asked to name their commissioner in random phone calls, but 89 per cent did not know the answer.
In West Mercia 134,750 people voted across Worcestershire, Telford and Wrekin, Herefordshire and Shropshire, resulting in independent candidate Bill Longmore becoming this region?s first elected police chief on a ?75,000 salary.
Adrian Blackshaw, who stood as the Conservative candidate against Mr Longmore, said the election had been ?badly handled?.
?The timing of the poll next time must not be in November,? he said.
?There is a timetable in place and enough time to make sure that doesn?t happen again, and I also think candidates paying ?5,000 (deposit) makes it an expensive exercise.
?It was handled badly. People need to get together and improve it for next time.?
His criticism echoed the society?s report, which cited the ?huge deposits, vast electoral districts and high campaign costs? as reasons to put potential candidates off.
It concludes that in 2016, the year of the next PCC elections, the poll should not be in the winter and that details on each candidate should be posted to voters.
Since being elected, Mr Longmore has alrady made some major decisions - include freezing West Mercia Police?s portion of the council tax bill, and launching a consultation over closing down or relocating up to 31 police bases.
He also wants to extend the powers of Police Community Support Officers (PCSOs) so they provide more assistance in fighting crime.
Councillor Jabba Riaz, who sits on the police and crime panel, which monitors Mr Longmore, said: ?I?m not surprised by the findings - what was most disappointing for me was the fact many people didn?t know who their candidates were in the election run-up.?

Cardinal's departure darkens mood as pope allows early conclave
VATICAN CITY (Reuters) - A senior cleric resigned under duress on Monday and Pope Benedict took the rare step of changing Vatican law to allow his successor to be elected early, adding to a sense of crisis around the Roman Catholic Church.
With just three days left before Benedict becomes the first pope in some six centuries to step down, he accepted the resignation of Britain's only cardinal elector, Archbishop Keith O'Brien, who was to have voted for the next pope.
O'Brien, who retains the title of cardinal, has denied allegations that he behaved inappropriately with priests over a period of 30 years, but said he was quitting the job of archbishop of Edinburgh.
He could have attended the conclave despite his resignation because he is still a cardinal under 80, but said he would stay away because he did not want media attention to be focused on himself instead of the process of choosing the next leader of the 1.2 billion-member Church.
His dramatic self-exclusion came as the Vatican continued to resist calls by some Catholics to stop other cardinals tainted by sex scandals, such as U.S. Cardinal Roger Mahony, from taking part.
Catholic activists have petitioned Mahony to exclude himself from the conclave so as not to insult survivors of sexual abuse by priests committed while he was archbishop of Los Angeles.
In that post from 1985 until 2011, Mahony worked to send priests known to be abusers out of state to shield them from law enforcement scrutiny in the 1980s, according to church files unsealed under a U.S. court order last month.
CRISIS MANAGEMENT
Benedict changed parts of a 1996 constitution issued by his predecessor John Paul so that cardinals could begin a secret conclave to choose a successor earlier than the 15 days after the papacy becomes vacant, as prescribed by the previous law.
The change means that in pre-conclave meetings starting on March 1, a day after Benedict leaves on Thursday, they can themselves decide when to start.
Some cardinals believe a conclave, held in secret in the Vatican's Sistine Chapel, should start sooner than March 15 in order to reduce the time in which the Church will be without a leader at a time of crisis.
But some in the Church believe that an early conclave would give an advantage to cardinals already in Rome and working in the Curia, the Vatican's central administration and the focus of accusations of ineptitude and alleged sexual scandals that some Italian newspapers speculate in unsourced reports led Benedict to step down. The Vatican says the reports are false.
The Vatican appears to be aiming to have a new pope elected by mid-March and installed before Palm Sunday on March 24 so he can preside at Holy Week services leading to Easter.
Cardinals have begun informal consultations by phone and email in the past two weeks since Benedict said he was quitting.
Benedict's papacy was rocked by scandals over the sexual abuse of children by priests, most of which preceded his time in office but came to light during it and which, as head of the Church, he was responsible for handling.
His reign also saw Muslim anger after he compared Islam to violence. Jews were upset over his rehabilitation of a Holocaust denier. And, during a scandal over the Church's business affairs, his butler was convicted of leaking his private papers.

Quantum algorithm breakthrough: Performs a true calculation for the first time
Feb. 24, 2013 ? An international research group led by scientists from the University of Bristol, UK, and the University of Queensland, Australia, has demonstrated a quantum algorithm that performs a true calculation for the first time. Quantum algorithms could one day enable the design of new materials, pharmaceuticals or clean energy devices.
The team implemented the 'phase estimation algorithm' -- a central quantum algorithm which achieves an exponential speedup over all classical algorithms. It lies at the heart of quantum computing and is a key sub-routine of many other important quantum algorithms, such as Shor's factoring algorithm and quantum simulations.
Dr Xiao-Qi Zhou, who led the project, said: "Before our experiment, there had been several demonstrations of quantum algorithms, however, none of them implemented the quantum algorithm without knowing the answer in advance. This is because in the previous demonstrations the quantum circuits were simplified to make it more experimentally feasible. However, this simplification of circuits required knowledge of the answer in advance. Unlike previous demonstrations, we built a full quantum circuit to implement the phase estimation algorithm without any simplification. We don't need to know the answer in advance and it is the first time the answer is truly calculated by a quantum circuit with a quantum algorithm."
Professor Jeremy O'Brien, director of the Centre for Quantum Photonics at the University of Bristol said: "Implementing a full quantum algorithm without knowing the answer in advance is an important step towards practical quantum computing. It paves the way for important applications, including quantum simulations and quantum metrology in the near term, and factoring in the long term."
The research is published in Nature Photonics.

(AP Photo/Jacquelyn Martin, File)
WASHINGTON (AP) ? Secretary of State John Kerry embarked Sunday on his first official overseas voyage in a diplomatic mission to bring new ideas to capitals in Europe and the Middle East on how to end nearly two years of brutal violence in Syria.
Kerry left Washington to start a grueling nine-nation, 10-day trip that will take him to America's traditional western European allies of Britain, Germany, France and Italy along with Turkey, Egypt, Saudi Arabia, the United Arab Emirates and Qatar. In addition to Syria, he will focus on conflicts in Mali and Afghanistan and Iran's nuclear program.
Kerry has said he is eager to discuss new ways of convincing Syrian President Bashar Assad to step down and usher in a democratic transition in the country that has been wracked by increasing violence that has killed at least 70,000 people. He has not offered details of his ideas but officials say they revolve around increasing pressure on Assad and his inner circle.
Kerry begins his trip in London where he will see senior British officials on a range of issues, from Afghanistan to the status of the Falkland Islands, over which Britain is in a major dispute with Argentina.
He then travels to Germany to discuss trans-Atlantic issues with German youth in Berlin, where he spent time as a child as the son of an American diplomat posted to the divided Cold War city. He will also meet with Russian Foreign Minister Sergey Lavrov in the German capital.
In Paris, Kerry will discuss France's ongoing intervention in Mali. And in Rome, he'll attend a meeting with Syrian opposition leaders.
U.S. officials have said the trip will be primarily a "listening tour" when it comes to Syria and won't result in immediate shifts in U.S. policy that has until now stayed clear of military support for the rebels fighting Assad.
Despite the numerous Middle East stops. Kerry will not travel to Israel or the Palestinian territories. He will wait to visit them when he accompanies President Barack Obama there in March.

Prep boys golf: Marin Academy team motivated to reclaim BCL West title
IT WAS A bittersweet, but yet satisfying, ending to the 2012 season for the Marin Academy boys golf team.
On one hand, the Wildcats have built a strong program that could compete against the MCAL's best. They captured the NCS Division II championship, believed to be the program's first NCS title.
However, MA had one accomplishment missing on an otherwise impressive resume. That was the defense of its league championship.
Marin Academy finished second to the Bay School for the Bay Counties West title last spring. They watched their bid for a third straight league title fall short.
"Getting second at the league tournament was really a

Buoyed by a strong top three of LaHorgue, Matt Cutcliffe and Will Bednarz, the Wildcats are aiming for redemption and to regain its hold atop the BCL West.
"We've been pretty hyped for this February to come," Cutcliffe said.
Despite the losses of key senior leaders in Alex Hartzell and Bobbie Lahmann, MA is eagerly anticipating how its new core will perform in what should be another competitive race in the league.
Marin Academy should be one of the favorites, and back
at full strength after LaHorgue missed a large part of the regular season last year. The third-year player played the first three matches before an appendectomy sidelined him until the league tournament.His return couldn't have come at a better time.
"It was tough to sit on the sidelines and watch the team play," LaHorgue said. "I was really motivated (to return) and practiced my short game a lot."
The friendship between LaHorgue and Cutcliffe, which began in kindergarten, is

a driving factor toward the team's success. They have naturally stepped up as the team's leaders and are now the Wildcats' top two golfers."We've coached each other to get better," LaHorgue said. "We don't have a competitiveness between us as far as trying to beat each other. But it's really great in pushing each other to work hard and having friendly competition in practice."
The addition of Bednarz, a freshman, gives MA as strong of a 1-2-3 punch at the top of the lineup as any team in the area.
Bednarz said the trio prepared a great deal for the upcoming season, playing together several times at Meadow Club. They formed a bond, which they hope translates into success this spring.
"I've known them for about a year now," Bednarz said. "They're kind of like big brothers to me. I practice with them a lot and they've helped me with my game mentally and physically."
The Wildcats round out their lineup with two solid freshmen ? Matt Kingsley and Seiichiro Nakai. Not only is the team's outlook bright today, but for the future as well.
And the next goal for Marin Academy is to win back the BCL West title.
"It'd mean a lot," LaHorgue said. "It's high up on our priorities right now. It'd be really great to get that banner."

Sefko: Ex-Mavs coach Don Nelson says Morrow is 2nd-best ?pure shooter? he?s coached
Click here to read Eddie Sefko?s entire column.
NEW ORLEANS ? The Mavericks didn?t have to go far to get the lowdown on the player they finally settled on to help them at the trade deadline.
When Don Nelson coached at Golden State, he was there for Anthony Morrow?s first two seasons in the NBA. When Nelson?s son, Mavericks president of basketball operations Donnie Nelson called to get a scouting report, he liked what he heard.
?Next to Chris Mullin,? the former Mavericks coach said, ?[Morrow?s] probably the best pure shooter I ever coached. You?re going to love him.?
The Mavericks clearly felt they needed a high-quality shooter more than they needed a tough-nosed defender as the NBA trade deadline passed Thursday afternoon.
They didn?t exactly blow the league away with their acquisition of the 27-year-old Morrow, but by giving up Dahntay Jones, the Mavericks made a commitment to getting Dirk Nowitzki, Vince Carter and Shawn Marion some help in the form of perimeter shooting.
Morrow is a career 42.5 percent 3-point shooter. He had trouble getting on the court this season with the Atlanta Hawks. But he was a double-figure scorer his first four seasons in the league, including a career-best 13 points per game in his second season with the Warriors.
?From training camp, we?ve talked about the lack of shooting,? Donnie Nelson said. ?It?s been a pretty significant hole. And to have a guy step in who?s one of the top stretch shooters maybe in the history of the league and provide some help there was just really, really important to us.?
It certainly wasn?t the sort of big splash that will turn around the Mavericks? season. They are five games below .500 and 4 1/2 games out of the final playoff spot. It will remain an uphill climb, and they know Morrow won?t be any sort of savior. But he can help. And at this point, that?s what the Mavericks need.
And they did it without sacrificing flexibility in the summer. Morrow?s $4 million expiring contract is $1 million more than Jones?, which also ends after this season.
And while defense wins in the NBA, this version of the Mavericks needs scoring from the perimeter since it has been difficult at times to put points on the board from closer range.
?He?s one of the best shooters in the game,? Mavericks coach Rick Carlisle said of Morrow. ?And you can never have too many shooters.

Alligators sport always-erect, hidden penises
YouTube
Alligators use bizarre, permanently erect penises that pop out of their bodies and are sucked back in just as quickly.
By Tia Ghose
LiveScience
Unlike many other reptiles and mammals, alligators sport permanently erect penises that hide inside their bodies, new research reveals.
The reptiles sport fully erect penises made of tough, fibrous tissue that shoot out of their bodies and get pulled back in just as quickly, according to the study, which is detailed in the March issue of the journal Anatomical Record.
"It is really interesting and really bizarre, very different from anything we've seen in vertebrates," said study author Diane Kelly, an anatomist at the University of Massachusetts.
Alligator mystery
Very little was known about how alligators mate, Kelly told LiveScience. In 1915, one scientist briefly described the alligator penis in a paper, but "at the end of it he actually says something to the effect of 'I have no idea how this thing works,'" Kelly said. [The Weirdest Animal Penises]
To find out, Kelly procured a few dead American alligators from the Rockefeller Wildlife Refuge in Louisiana, one of which was more than 13 feet (4 meters) long. She dissected the alligator and was surprised at what she found.
Hidden inside the alligator's waste and reproductive orifice, known as a cloaca (which is Latin for "sewer"), was a nearly 2.75-inch (7-centimeter)-long, pasty white phallus.
When she dissected the penile tissue, she found it was filled with a stiff, fibrous material called collagen. Kelly then filled the penis with saline fluid. In mammals, turtles and birds, inflating the vascular region of a penis with saline enlarges it, allowing anatomists to see how the penis becomes erect.
"I tried it with the alligator and I got no length change, I got no diameter change. I got nothing," Kelly said. "It became very clear to me right then and there that there was something very different."
Kelly surmised that the vascular space inside the alligator penis was so full of collagen that it was simply too stiff to inflate.
To see how it popped in and out of the alligator's body, she tugged on various tendons and muscles in the cloaca region and found one set of muscles that caused the penis to shoot out. Another set of tendons attaches to the base of the penis like rubber bands, she said.
"As soon as those muscles relax, the penis gets whipped back into its original position."
Kelly isn't sure whether the penis comes out only during mating or also at other times, though she thinks it's the former. Since crocodiles and alligators are closely related, crocodile penises probably work the same way, she said, though she and other scientists have never studied the crocodile penis.
As a next step, Kelly is teaming up with researcher Brandon Moore at Louisiana Tech University, who is studying the ejaculatory system of the alligator.
"He was doing the glans end, and I was doing the rectal end, and we figured between the two of us we can do a really good job of getting the whole thing described."

Mumford & Sons, Adele among winners at Brit Awards
LONDON (AP) ? British music put on a brash, confident show at the Brit Awards on Wednesday, celebrating a resurgent industry whose bands and artists are topping charts around the globe.
Winners ranged from established acts such as Coldplay and Adele to world-conquering boy band One Direction, who won in the new Global Success category.
One Direction's Louis Tomlinson called the prize "absolutely mind-blowing."
American artists Frank Ocean and Lana Del Rey were among the non-British winners at a ceremony that embraced the mainstream while rewarding artists with distinctive personalities.
Surfing English folk singer Ben Howard and chanteuse Emeli Sande each won two awards.
Sande was named best British female artist and won the album of the year prize for her debut "Our Version of Events," which has been in the British charts for more than a year. Scotland-raised Sande got a big boost in 2012 when she performed at both the opening and closing ceremonies of the Olympics.
"This is a dream, really," said Sande, who beat Alt-J, Mumford & Sons, Plan B and Paloma Faith to the album prize.
She thanked everyone "who made me feel like I'm part of something much bigger."
Howard was named British breakthrough act and British male artist of the year.
"I'm not very good at speeches," the 25-year-old singer said, accurately ? though he may have to get good at it if his career continues to take off.
Long derided as dull, the Brits have become a lively celebration of "Cool Britannia" music and style, featuring a dinner for hundreds of artists and industry figures followed by a televised concert and awards show for thousands of paying fans.
Hard rockers Muse opened the show at London's O2 Arena with a typically robust performance of their song "Supremacy"? all thundering music, dazzling light show and 60-piece orchestra. Other performers ranged from tween-pleasing One Direction to American artists Taylor Swift and Justin Timberlake.
Timberlake, dapper in a tuxedo as he performed "Mirrors," was described by host James Corden, in a nod to Europe's horse meat scandal, as "95 percent beefcake with just a little touch of horse."
One Direction performed a mashup of post-punk classics "One Way or Another" and "Teenage Kicks," their single for Britain's Comic Relief charity.
Mumford & Sons were named best British group. The banjo-twanging band topped U.K. and U.S. charts with their second album "Babel," which was named album of the year at the Grammys earlier this month.
Soul singer Amy Winehouse ? who died in July 2011 from accidental alcohol poisoning ? was among the other nominees for British female artist, eligible thanks to her posthumous "Lioness: Hidden Treasures" album. Her father, Mitch Winehouse, arrived for the awards ceremony at London's O2 Arena wearing a waistcoat emblazoned with a picture of his daughter.
Coldplay was named best British live act, beating nominees including The Rolling Stones, who celebrated their 50th anniversary with a series of sold-out shows last year.
Adele won the best British single prize for her James Bond theme "Skyfall." The soulful singer sent a message from Los Angeles, where she is rehearsing for Sunday's Academy Awards.
There was no repeat of last year, when she was cut-off mid-speech because the show was running late ? an incident Corden referred to in mock-embarrassment several times.
The Black Keys were named best international group, while Del Rey took the trophy for international female solo artist. The U.S. singer, who began as an Internet sensation, won a breakthrough Brit award last year and on Wednesday thanked Britain for supporting her.
The international male trophy went to R&B star Frank Ocean, who said it was "definitely a long way from working fast food in New Orleans" ? and was the only winner to thank artist Damien Hirst for creating the polka-dot Brit Awards statuette.
Style standouts included Swift, who performed "I Knew You Were Trouble" in a hoop-skirted white number ? more wedding cake than wedding dress ? that she shed to reveal black undergarments. Jessie J drew attention in a deeply low-cut black dress.
Most of the awards are chosen by more than 1,000 musicians, critics and record industry figures, with several decided by public vote.

Robotic bat wing engineered: Researchers uncover flight secrets of real bats
Feb. 21, 2013 ? The strong, flapping flight of bats offers great possibilities for the design of small aircraft, among other applications. By building a robotic bat wing, Brown researchers have uncovered flight secrets of real bats: the function of ligaments, the elasticity of skin, the structural support of musculature, skeletal flexibility, upstroke, downstroke.
Researchers at Brown University have developed a robotic bat wing that is providing valuable new information about dynamics of flapping flight in real bats.
The robot, which mimics the wing shape and motion of the lesser dog-faced fruit bat, is designed to flap while attached to a force transducer in a wind tunnel. As the lifelike wing flaps, the force transducer records the aerodynamic forces generated by the moving wing. By measuring the power output of the three servo motors that control the robot's seven movable joints, researchers can evaluate the energy required to execute wing movements.
Testing showed the robot can match the basic flight parameters of bats, producing enough thrust to overcome drag and enough lift to carry the weight of the model species.
A paper describing the robot and presenting results from preliminary experiments is published in the journal Bioinspiration and Biomimetics. The work was done in labs of Brown professors Kenneth Breuer and Sharon Swartz, who are the senior authors on the paper. Breuer, an engineer, and Swartz, a biologist, have studied bat flight and anatomy for years.
The faux flapper generates data that could never be collected directly from live animals, said Joseph Bahlman, a graduate student at Brown who led the project. Bats can't fly when connected to instruments that record aerodynamic forces directly, so that isn't an option -- and bats don't take requests.
"We can't ask a bat to flap at a frequency of eight hertz then raise it to nine hertz so we can see what difference that makes," Bahlman said. "They don't really cooperate that way."
But the model does exactly what the researchers want it to do. They can control each of its movement capabilities -- kinematic parameters -- individually. That way they can adjust one parameter while keeping the rest constant to isolate the effects.
"We can answer questions like, 'Does increasing wing beat frequency improve lift and what's the energetic cost of doing that?'" Bahlman said. "We can directly measure the relationship between these kinematic parameters, aerodynamic forces, and energetics."
Detailed experimental results from the robot will be described in future research papers, but this first paper includes some preliminary results from a few case studies.
One experiment looked at the aerodynamic effects of wing folding. Bats and some birds fold their wings back during the upstroke. Previous research from Brown had found that folding helped the bats save energy, but how folding affected aerodynamic forces wasn't clear. Testing with the robot wing shows that folding is all about lift.
Studying an animal with unique abilities
Over the years, Kenneth Breuer, an engineer, and Sharon Swartz, a biologist, have developed a large archive of bat data, from wind tunnels to field studies and slow-motion video.In a flapping animal, positive lift is generated by the downstroke, but some of that lift is undone by the subsequent upstroke, which generates negative lift. By running trials with and without wing folding, the robot showed that folding the wing on the upstroke dramatically decreases that negative lift, increasing net lift by 50 percent.
Data like that will not only give new insights into the mechanics of bat flight, it could aid the design of small flapping aircraft. The research was funded by the U.S. Air Force Office of Scientific Research and the National Science Foundation..
Inspired by the real thing
Bat wings are complex things. They span most of the length of a bat's body, from shoulder to foot. They are supported and moved by two arm bones and five finger-like digits. Over those bones is a super-elastic skin that can stretch up to 400 percent without tearing. The eight-inch robot mimics that anatomy with plastic bones carefully fabricated on a 3-D printer to match proportions of a real bat. The skin is made of a silicone elastomer. The joints are actuated by servo motors that pull on tendon-like cables, which in turn pull on the joints.
The robot doesn't quite match the complexity of a real bat's wing, which has 25 joints and 34 degrees of freedom. An exact simulation isn't feasible given today's technology and wouldn't be desirable anyway, Bahlman said. Part of why the model is useful is that it distills bat flapping down to five fundamental parameters: flapping frequency, flapping amplitude, the angle of the flap relative to the ground, the amount of time used for the downstroke, and the extent to which the wings can fold back.
Experimental data aside, Bahlman said there were many lessons learned just in building the robot and getting it to work properly. "We learned a lot about how bats work from trying to duplicate them and having things go wrong," he said.
During testing, for example, the tongue and groove joint used for the robot's elbow broke repeatedly. The forces on the wing would spread open the groove, and eventually break it open. Bahlman eventually wrapped steel cable around the joint to keep it intact, similar to the way ligaments hold joints together in real animals.
The fact that the elbow was a characteristic weak point in the robot might help to explain the musculature of elbows in real bats. Bats have a large set of muscles at the elbow that are not positioned to flex the joint. In humans, these muscles are used in the motion that helps us turn our palms up or down. Bats can't make that motion, however, so the fact that these muscles are so large was something of a mystery. Bahlman's experience with the robot suggests these muscles may be adapted to resist bending in a direction that would break the joint open.
The wing membrane provided more lessons. It often tore at the leading edge, prompting Bahlman to reinforce that spot with elastic threads. The fix ended up looking a lot like the tendon and muscle that reinforce leading edges in bats, underscoring how important those structures are.
Now that the model is operational, Bahlman has lots of plans for it.
"The next step is to start playing with the materials," he said. "We'd like to try different wing materials, different amounts of flexibility on the bones, looking to see if there are beneficial tradeoffs in these material properties."

Searching for the solar system's chemical recipe
Feb. 20, 2013 ? By studying the origins of different isotope ratios among the elements that make up today's smorgasbord of planets, moons, comets, asteroids, and interplanetary ice and dust, Mark Thiemens and his colleagues hope to learn how our solar system evolved. Thiemens, Dean of the Division of Physical Sciences at the University of California, San Diego, has worked on this problem for over three decades.
In recent years his team has found the Chemical Dynamics Beamline of the Advanced Light Source (ALS) at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) to be an invaluable tool for examining how photochemistry determines the basic ingredients in the solar system recipe.
"Mark and his colleagues Subrata Chakraborty and Teresa Jackson wanted to know if photochemistry could explain some of the differences in isotope ratios between Earth and what's found in meteorites and interplanetary dust particles," says Musahid (Musa) Ahmed of Berkeley Lab's Chemical Sciences Division, a scientist at the Chemical Dynamics Beamline who works with the UC San Diego team. "They needed a source of ultraviolet light powerful enough to dissociate gas molecules like carbon monoxide, hydrogen sulfide, and nitrogen. That's us: our beamline basically provides information about gas-phase photodynamics."
Beamline 9.0.2, the Chemical Dynamics Beamline, generates intense beams of VUV -- vacuum ultraviolet light in the 40 to 165-nanometer wavelength range (a nanometer is a billionth of a meter)- which can be precisely tuned to mimic radiation from the protosun when the solar system was forming.
Oxygen and sulfur are the third and tenth most abundant elements in the solar system and two of the most important for life. Their isotopic differences from Earth's are clearly seen in many different kinds of meteorites. Thiemens's team first used beamline 9.0.2 in 2008 to test a theory, called "self-shielding," about why oxygen-16 is less prevalent in these relics of the primitive solar system than it is in the sun, which contains 99.8 percent of all the mass in the solar system. To their surprise, the experimental results showed that self-shielding could not resolve the oxygen-isotope puzzle.
More recently Thiemens's group used beamline 9.0.2 to perform the first VUV experiments on sulfur, using the results to build a model of chemical evolution in the primitive solar nebula that could yield the isotopic ratios of sulfur seen in meteorites. They report their findings in Proceedings of the National Academy of Sciences.
Mass versus chemistry
Oxygen is the most abundant element on Earth, present in air, water, and rocks; 99.762 percent of it is the isotope oxygen-16, with eight protons and eight neutrons. Oxygen-18 has two additional neutrons and accounts for another two-tenths of a percent; oxygen-17, with one extra neutron, provides the last smidgen, less than four-hundredths of a percent.
Sulfur, with four stable isotopes, is less abundant but essential to life. Sulfur-32 accounts for 95.02 percent, sulfur?34 4.21 percent, sulfur-33 0.75 percent, and sulfur-36's mere 0.02 percent brings up the rear.
Ahmed explains the two basic kinds of processes that account for these ratios. "One depends on the mass of the isotopes themselves," he says. "Oxygen-18 is two neutrons heavier than oxygen-16. One effect of this, although not the only one, is that when the temperature rises, oxygen-16 evaporates faster. And when the temperature falls, oxygen-18 condenses faster."
Changes in temperature and other physical factors can thus produce different isotope ratios -- that's why there's a greater proportion of oxygen-18 in raindrops than in the clouds they fall from, for example.
Isotope-ratio researchers commonly graph these processes by plotting samples with increasing proportions of oxygen-18 relative to oxygen-16 along the Y axis; the X axis shows increasing proportions of oxygen-17 to oxygen-16. When comparing these three isotopes in almost any sample from Earth to an arbitrary standard called SMOW (standard mean ocean water), the proportions of the three always diverge at a rate that can be plotted along a line with a distinctive slope: about one-half.
Samples whose isotope ratios don't fall on the slope-one-half line didn't result from mass-dependent processes. In 1973 the ratios of oxygen isotopes in carbonaceous meteorites, the oldest objects in the solar system, were found to vary significantly from those on Earth. Their graph line had a slope close to one. A decade later Thiemens and John Heidenreich found that ozone, the three-atom molecule of oxygen, showed a similar isotope trend, with a similar slope of one -- a relationship that was at least partly due to the molecule's chemical formation.
Sulfur isotope ratios are plotted in a similar way; the standard is an iron sulfide mineral called Diablo Canyon Troilite -- not native to Earth, however, but found in a fragment of the meteorite that created Arizona's Meteor Crater.
"Mass-independent processes suggest chemical reactions, whether in the lab, the stratosphere, or the early solar system," says Ahmed. "In the proto-solar system, bathed in intense ultraviolet light, these might have occurred on a grain of rock or ice or dust, or in just plain gas. The goal is to identify distinctive isotopic fractionations and examine the chemical pathways that could have produced them."
In the beginning
Since Thiemens's early work with ozone 30 years ago, his UC San Diego laboratory has perfected methods of recovering primordial samples from dust, meteorites, and the solar wind. Thiemens and Chakraborty were members of the science team for NASA's Genesis mission, and Chakraborty was able to extract mere billionths of a gram of oxygen from particles of the solar wind even after the spacecraft's collectors were badly damaged when they crashed upon return to Earth.
Like oxygen, sulfur isotopes show up in different fractions in different solar system sources. Tracing their possible origins, the recent study of sulfur isotopes at beamline 9.0.2 began by flowing hydrogen sulfide gas -- the most abundant sulfur-bearing gas in the early solar system -- into a pressurized reaction chamber, where the synchrotron beam decomposed the gas and deposited elemental sulfur on "jackets" made of ultraclean aluminum foil.
The experiment was performed at four different VUV wavelengths, and the carefully stored aluminum jackets were taken to the Thiemens lab in San Diego, where Chakraborty and Jackson chemically extracted the sulfur and then measured its isotopes using Isotope Ratio Mass Spectrometry. In all samples the isotope compositions were found to be mass independent.
One source of fractionation in nature was photodissociation of hydrogen sulfide as the gas condensed to iron sulfide in the inner solar system, driven by intense 121.6-nanometer-wavelength ultraviolet light as the young star repeatedly shook with violent flares and upheavals. Different classes of meteorites -- and different parts of the same meteorites, such as their crust or various inclusions -- subsequently evolved different isotope ratios, depending on where and when in the solar system they formed. Sulfur compositions evolved independently from the way oxygen isotope compositions evolved.
The most recent target of research by the Thiemens group at beamline 9.0.2 is nitrogen, the seventh most abundant element in the solar system. On Earth, 99.63 of nitrogen is nitrogen-14, and nitrogen-15 is the remaining 0.37 percent. Measurements of the solar wind, carbonaceous meteorites, and other sources show wide swings in their proportions. The work is ongoing.
Says Musa Ahmed, "Tracking down how isotopic ratios may have evolved, we basically send these elements back in time. The more we learn about the fundamental elements of the solar system at the Chemical Dynamics Beamline, the more it's like really being out there when the solar system began."
This work was funded by NASA's Origins and Cosmochemistry programs. The Advanced Light Source is supported by DOE's Office of Science.

Hirsute in a huff over Gillette ads in Brazil
SAO PAULO (AP) ? Hate that hair? In Brazil, beware.
A self-regulatory council for Brazil's advertising industry is looking into complaints against razor maker Gillette for running body-shaving commercials.
Council spokesman Eduardo Correa says 20 consumers have filed complaints that the campaign "encourages prejudice against hairy men."
The online commercials show beautiful women telling men they should shave their chests to please their girlfriends.
The council's ethical committee is expected to rule on the case in 30 days.
Elaine Moreira is a spokeswoman for Gillette parent company Procter & Gamble. She says the campaign was "an irreverent way to say that women prefer hairless men and that the company never meant to offend consumers."

NVIDIA unveils the GTX Titan, an enormous graphics card that costs $1,000 (eyes-on)
NVIDIA's GTX Titan is rumor no more, as the American computer hardware company unveiled the superpowerful graphics card this morning. With 2,688 CUDA cores, 6GB of GDDR5 RAM, and 7.1 billion transistors packed into the 10.5-inch frame, Titan's capable of pushing 4,500 Gigaflops of raw power -- NVIDIA's pitching Titan as the means to "power the world's first gaming supercomputers." The company even showed off the Titan in its mightiest form, bootstrapped to two others running together (three-way SLI), which powers graphics showcase Crysis 3 running at its highest settings: a whopping 5760x1080 resolution across three monitors. Of course, a setup like that would cost you quite a pretty penny; just one GTX Titan costs $1,000, not to mention three (nor all the other hardware required to support it).
Should you prefer your gaming PCs to not be of the neon-lit, triple GPU, above-$10,000 variety, NVIDIA was also showing off the Titan in a Falcon Northwest boutique PC. The company's working with a variety of boutique PC makers to incorporate the Titan (see: Maingear), making NVIDIA's top of the line a teensy bit more accessible to your average joe.
GTX Titan is the new top of the line for NVIDIA, effectively pushing aside the GTX 690 and setting a new benchmark for performance. Of course, with a $1,000 price tag and freedom -- nay, encouragement -- to tweak its nitty gritty settings, the Titan isn't really meant for your average anyone. The PC game-playing early adopters, however? Here's your next GPU. Hopefully you've got a big, empty space in your rig, as you'll need it. The GTX Titan arrives on February 25th for $999.

BOSTON -- Society currently faces profound social and environmental challenges that must be met to secure a sustainable future for humanity. A major challenge in achieving this goal is discovering how best to synthesize important findings and ideas from many disciplines and use them to produce scientifically informed social and environmental policy.
This task is not easy. Different disciplines use different theories and methods, and scientists and policy makers rarely work together. New types of research centers are needed, as are new ways of organizing collaborations between scientists and between scientists and policy makers.
New research by John Parker of Barrett, The Honors College at Arizona State University and Edward Hackett of ASU's School of Human Evolution and Social Change works to identify the specific types of research environments and social interactions that facilitate success in these collaborations.
Parker presented the team's analysis of factors that facilitate cross-disciplinary collaborations between scientists and policy makers today (Feb. 18), at the 2013 annual meeting of the American Association for the Advancement of Science. His talk was titled "Ecology Transformed: NCEAS and Organizing for Synthesis."
Parker and Hackett are using novel, state-of-the-art research instruments known as "sociometric sensors" in their investigation. These are wearable computers that record data about how scientists and policy makers interact with each other, including movement, vocal tones, interruptions, volume and other conversational nuances.
They will use these sensors to study scientists working on real problems at several research centers around the world with the aim of identify patterns of social interaction that are best related to collaborative success. Sensor data will also be integrated with interviews, surveys and observations of the scientists.
Hackett and Parker hope that the groundwork they build in these studies will pave the way for future research on the same topic and allow for the creation of new types of research centers capable of meeting the challenges of the future. Their work also has implications for ASU's vision as The New American University.
"What we are doing," Parker said, "is related to what ASU is trying to do on a larger scale. By embedding engagement into activities, the university hopes to positively impact the social and environmental development of individuals and the community as a whole."
