Slow-motion replays of deep passes have mesmerized fans of American football for decades. The impossibly long, steady arc of a well-thrown ball is a thing of beauty. In contrast, players sometimes refer to wobbly passes as ugly ducks, although just why isn't entirely clear, since ducks fly pretty well.

In Andrew Lloyd Webber’s 1970 rock opera Jesus Christ Superstar , a skeptical Judas Iscariot questions with faux innocence (“Don’t you get me wrong/I only want to know”) the messiah’s deific nature: “Jesus Christ Superstar/Do you think you’re what they say you are?”
[More]Brain Injury Rate 7 Times Greater among U.S. Prisoners ...
A car accident, a rough tackle, an unexpected tumble. The number of ways to bang up the brain are almost as numerous as the people who sustain these injuries. And only recently has it become clear just how damaging a seemingly minor knock can be. Traumatic brain injury (TBI) is no longer just a condition acknowledged in military personnel or football players and other professional athletes. Each year some 1.7 million civilians will suffer an injury that disrupts the function of their brains, qualifying it as a TBI.
[More]Homeless Project Residents Drink Less If Booze Ban Is Lifted ...
This Sunday, millions of Americans will sit down in front of their television or computer, crack open a few beers, and watch the Super Bowl. But if those viewers live in a housing project for the homeless, that booze could get them booted back out to the street. Many homeless housing projects have strict abstinence policies, and require residents to be completely sober. Permitting alcohol, many community organizers reason, would enable addictions and promote a downward spiral into continued drinking and declining health.

[More]Close Super Bowl Boosts Ad At End ...
Advertisers will drop $3.5 million for a 30-second spot during Sunday’s Super Bowl. But to get the most bang for their buck, they might want to play their ad right after the game ends--not during it. Because if it's a close one, the time slot right after the final gun should have the most sway with viewers. So says a study in the Journal of Advertising . [ Colleen C.

Some Africans click, but English speakers don’t. That’s been the conventional wisdom about click sounds, which serve as regular consonants in Zulu and Xhosa and a few other African languages but which were presumed to just be used in English for encouraging a horse, imitating a kiss, or expressing emotions such as disapproval or amazement. But researchers have recently found that clicks are far more prevalent in the world’s lingua franca than had been thought.

In my last post , I focused on flaws in the medical device approval process. The Union of Concerned Scientists FDA at a Crossroads meeting also covered problems with drug approval. This is perhaps no better illustrated than by the disappointing decision by Secretary of Health Kathleen Sebelius to deny the emergency contraceptive, Plan B, over-the-counter status for women under the age of 17 . This was a particular disappointment to many because President Obama had promised that decisions at the FDA would be made based on science, rather than politics. Some of us, naively, hoped that change we can believe in was real, having forgotten that the Tooth Fairy wasn t.

[More]Could an Infection Cause Tourette's-Like Symptoms in Teenage Girls? ...
Over the weekend Erin Brockovich made the news yet again as she and her nonprofit team descended on the village of Le Roy, N.Y., determined to test for environmental toxins that might be giving the town's teenagers symptoms of Tourette's syndrome. She has reportedly been stonewalled thus far by local officials, who have already ruled out toxins as the cause of last October's sudden outbreak of tics and involuntary movements in 12 girls who attend Le Roy Junior–Senior High School. An environmental testing company surveyed the air and water and found nothing amiss, and a local neurologist concluded upon examining the girls that they had "conversion disorder," a catchall moniker for physical symptoms that originate in the mind because of stress, trauma or even mass hysteria.
[More]Temperatures--Not Acid--Could Cook Coral to Death ...
One of the biggest natural tragedies of recent years is the deterioration of Australia's Great Barrier Reef , a vast structure of coral off the continent's east coast that supports a profusion of wildlife. In addition to overfishing and nutrient pollution, the world's largest natural structure has suffered from rising ocean temperatures. But, perhaps less well known, Australia's west coast has some massive reefs of its own, offshore in the southeastern Indian Ocean. Massive stony corals of the genus Porites swell to the surface, and new research published February 2 in Science suggests those located in the colder waters farthest south are growing better than ever --thanks to warming ocean temperatures.

Butterflies are not merely beautiful. They use a complex pattern of rapid wing flapping and body deformation to execute impressive aerial acrobatics. This ability has not escaped the U.S. military, which is turning to these insects for ideas on how to create ever-smaller drone aircraft to execute reconnaissance, search-and-rescue and environmental monitoring missions. [View a slide show featuring different drones used by the U.S. military.]
The Air Force Research Laboratory at Wright-Patterson Air Force Base in Ohio is testing drones less than 60 centimeters long roughly the wingspan of an Atlantic Puffin with the hope they will be able to operate below rooftop levels in city streets.

Accidental Kakapo Death Lowers Population of Rare, Flightless Parrots to 127 Birds ...
The death of an adult female kakapo ( Strigops habroptila ) on New Zealand’s Anchor Island this past weekend brings the population of these rare flightless parrots down to just 127 birds.
The late kakapo, known as Sandra, was killed when her transmitter harness got entangled in a tree. All kakapos are outfitted with transmitters to help rangers in the Kakapo Recovery program keep track of the birds. Sandra’s death marked the first time in 31 years of transmitter use that the devices have injured a bird.

Jordan Suchow came to three rapid-fire conclusions as he watched his Macintosh laptop plummet toward the floor. First, in approximately 300 milliseconds he was going to be in a heap of trouble--the machine had been given to him by his thesis adviser, George Alvarez of Harvard University. Second, hoping against all hope, he decided that Harvard could probably afford to buy him a new computer. Third, he realized that the most important observation of his life was unfolding right in front of him as his laptop accelerated toward the parquet: the onscreen doughnut that he had programmed to scintillate appeared to have stopped doing so.

At 6' 1" and roughly 230 pounds, he was slightly undersized for his position, but he had tremendous thrust in his legs and used all of it to launch himself into players who were bigger than he was. He played for the New England Patriots from 1992 to 1994, then joined the Philadelphia Eagles, with whom he stayed until his abrupt retirement in 1999. Some called him “the Collision Expert”--a nickname he got because of the gouges he collected on his helmet.

Conferences are social grooming events for relatively hairless apes. A few will stand before the multitude, beaming with pride or shaking with nervousness (as the case may be), and present the latest research in contemporary ape thought. As their vocalizations reach a crescendo, those sitting demurely below will produce flesh-slapping noises that indicate they were paying attention (even if they weren t). Another ape will then rise and this process will continue repeatedly and at length. It looks a lot like the modern political stump speech.
[More]Could Simple Experiments Reveal the Quantum Nature of Spacetime? ...
Conventional wisdom has it that putting the words quantum gravity and experiment in the same sentence is like bringing matter into contact with antimatter. All you get is a big explosion; the two just don t go together. The distinctively quantum features of gravity only show up in extreme settings such as the belly of a black hole or the nascent universe, over distances too small and energies too large to reproduce in any laboratory. Even alien civilizations that command the energy resources of a whole galaxy probably couldn t do it.
Physicists have never been much for conventional wisdom, though, and the dream of studying quantum gravity is too enthralling to give up. Right now, physicists don t really know how gravity works they have quantum theories for every force of nature except this one. And as Einstein showed, gravity is special: it is not just any old force, but a reflection of the structure of spacetime, on which all else depends. In a quantum theory of gravity, all the principles that govern nature will come together. If physicists can observe some distinctively quantum feature of gravity, they will have glimpsed the underlying unity of the natural world.

[More]Satellites to Track Rare Royal Turtle in Cambodia [Video] ...
A member of one of the world’s most endangered turtle species is being tracked by satellites as it swims the rivers of Cambodia, helping scientists to learn more about how it navigates and the threats it faces in its native waters. With a satellite transmitter glued to her shell, the female southern river terrapin ( Batagur affinis edwardmolli ) one of the last 200 wild members of a species which was once treasured by Cambodian royalty was released into the Sre Ambel River on January 16 in a ceremony attended by dozens of cheering local residents, government officials and international conservationists.
The terrapin’s travels will be monitored by the Wildlife Conservation Society (WCS) in conjunction with Wildlife Reserves Singapore and Cambodia’s Fisheries Administration. This is the first satellite study of the southern river terrapin, offering a rare opportunity to learn more about this species, which was named one of the world’s 25 most endangered turtle species in February 2011.

The pachyderms could help to polish off gamba grass, introduced from Africa to Australia in the 1930s as fodder for cattle. Nowadays, it also provides fuel for devastating fires, such the one that killed 173 people and burned 400,000 hectares on February 7, 2009. Neither local cattle nor kangaroos consume enough of the weedy grass to keep it in check.
