Orca The Dolphin Killer

The six-ton hunter chased the female dolphin through the waves before slamming into her, flipping her 30 feet into the air

From The Daily Mail:

This is the shocking moment a killer whale leapt from the sea to kill an exhausted dolphin.

The six-ton hunter had chased the female dolphin through the waves before swimming up under her and slamming into her, flipping her 30 feet into the air and breaking her back.

The dolphin died almost instantly and the killer whale, or orca, and the rest of its pod then closed in to devour her and her helpless youngster, turning the sea red.

From Science Daily:

ScienceDaily (Mar. 30, 2010) — By blocking the cellular signaling activity of a protein, a team of neuroscientists at Cold Spring Harbor Laboratory (CSHL) has prevented memory loss in fruit flies caused by brain plaques similar to those thought to cause Alzheimer's disease in humans. The study also resolves a long-standing controversy about the role of this protein, PI3 kinase, which was previously thought to have a protective function against the disease.

10 Questions The LHC May Answer


From Discovery News:

It's been just over a year since the Large Hadron Collider, the world's most powerful particle accelerator, suffered a serious malfunction that shut it down only nine days after going online. But as of this weekend, the LHC is back up and running.

Scientists will use the collider to recreate conditions following the Big Bang, by accelerating beams of subatomic particles (protons and lead ions, called hadrons) around a massive underground racetrack.

Since the decoding of the human genome, biotechnology companies have claimed that by matching a person’s genetic make-up with specialised treatments, they can tailor drugs to maximise benefits and minimise side effects. Alas, researchers have discovered that the link between a given person’s genetic make-up and specific diseases is much more complex than they had hoped. The tantalising vision remains out of reach.

Moral Judgments Can Be Altered

In a new study, researchers disrupted activity in the right temporo-parietal junction by inducing a current in the brain using a magnetic field applied to the scalp. They found that the subjects' ability to make moral judgments that require an understanding of other people's intentions -- for example, a failed murder attempt -- was impaired. (Credit: Graphic by Christine Daniloff)

From Science Daily:

ScienceDaily (Mar. 30, 2010) — MIT neuroscientists have shown they can influence people's moral judgments by disrupting a specific brain region -- a finding that helps reveal how the brain constructs morality.

To make moral judgments about other people, we often need to infer their intentions -- an ability known as "theory of mind." For example, if a hunter shoots his friend while on a hunting trip, we need to know what the hunter was thinking: Was he secretly jealous, or did he mistake his friend for a duck?

Mystery of Great Civilization's Destruction Revealed

From Live Science:

Climate change might have helped bring about the fall of the ancient Khmer civilization in Angkor, Cambodia, nearly 600 years ago, new research suggests.

Historians have given various explanations for the fall of the empire that stretched across much of Southeast Asia between the ninth and 14th centuries (801 to 1400), from land overexploitation to conflict with rival kingdoms. But the new study offers strong evidence that two severe droughts, punctuated by bouts of heavy monsoon rain, could have weakened the empire by shrinking water supplies for drinking and agriculture, and damaging Angkor's vast irrigation system, which was central to its economy.

Assault Breacher Vehicles Beat Bombs In Afghanistan



From Popular Mechanics:

Marine corps engineers in Afghanistan have a new beast of a vehicle to help them defeat explosive booby traps.

The civilian mechanics at Anniston Army Depot in Alabama usually only fix vehicles for the Army, not design them for the Marine Corps. But as Marines push into contested areas of Afghanistan, their engineers face a persistent threat from roadside bombs. The mechanics at Anniston saw they could build a safe ride for these military engineers by adding off-the-shelf equipment to an M1A1 Abrams battle tank. The result, called the Assault Breacher Vehicle (ABV), maximizes the depot staff’s experience at fixing the M1A1 and their ability to mount heavy engineering equipment, including a 12-foot plough, onto its hull. The Army donated excess tank parts from its inventory to create the ABV.
