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.

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?

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.

How It Works: Taser's Electrified Shotgun Slug


From Popular Science:

It’s midnight. You’re a cop patrolling the wrong side of town when you spot a mugging. The assailant is about 40 feet away, out of range of your stun gun. You shout, but he darts down an alley. It’s a dead end. The crook picks up a bottle, hurls it at your head, and makes a break for the street. You draw your gun.

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.

New iPhone Could End AT&T's U.S. Monopoly


From The Wall Street Journal:

Apple Inc. plans to begin producing this year a new iPhone that could allow U.S. phone carriers other than AT&T Inc. to sell the iconic gadget, said people briefed by the company.

The new iPhone would work on a type of wireless network called CDMA, these people said. CDMA is used by Verizon Wireless, AT&T's main competitor, as well as Sprint Nextel Corp. and a handful of cellular operators in countries including South Korea and Japan. The vast majority of carriers world-wide, including AT&T, use another technology called GSM.

US Marines Embrace Web 2.0


In About-Face, Marines Embrace Web 2.0 -- The Danger Room

Last summer, the U.S. Marine Corps took a draconian approach to Web 2.0, issuing a sweeping ban on Twitter, Facebook, MySpace and other social media sites from its networks.

In an order issued yesterday, the service changed course, issuing guidelines to encourage “responsible and effective use” of social networking technology. “The Marine Corps embraces and strives to leverage the advances of internet-based capabilities,” the directive states. “Effective immediately, internet-based capabilities will be made available to all MCEN [Marine Corps Enterprise Network] users.”

From MSNBC:

Space industry tense over pending demise of Constellation program.

CAPE CANAVERAL, FLA. - Anyone need a $500 million, 355-foot steel tower for launching rockets into space?

There's one available at NASA's Kennedy Space Center. Brand new, never been used.

The mobile launcher has been built for a rocket called the Ares 1. The problem is, there is not yet any such thing as an Ares 1 rocket — and if the Obama administration has its way, there never will be.

From Science Daily:

ScienceDaily (Mar. 30, 2010) — For a brief instant, it appears, scientists at Brook­haven National Laboratory on Long Island recently discovered a law of nature had been broken.

Action still resulted in an equal and opposite reaction, gravity kept the Earth circling the Sun, and conservation of energy remained intact. But for the tiniest fraction of a second at the Relativistic Heavy Ion Collider (RHIC), physicists created a symmetry-breaking bubble of space where parity no longer existed.

'Uranium-Eating' Bacteria To Clean-Up Radioactive Sites

Ranger Mine - a uranium mine in Kakadu National Park, Australia.

From Cosmos:


SYDNEY: Some bacteria have the capacity to stabilise uranium contaminated sites, and if they are used they could reducing the chances of these sites contaminating major waterways and ecosystems, U.S. scientists have said.

Of the millions of tonnes of bacteria living within the Earth's subsurface, some are able to transform the oxidative state of uranium, which defines how the element with interact with oxygen to form various molecules. They change it from the radioactive, toxic and water soluble uranium (VI) to the less soluble, stationary and therefore less harmful uranium (IV) as part of their normal growth.

From The Guardian:

Oxford neurobiologist Colin Blakemore tells Robin McKie why he thinks a mutation in the human brain 200,000 years ago suddenly made us a super-intelligent species.

According to Woody Allen, it is his second favourite organ and it absorbs more than 25% of the energy that our bodies generate. But why? For what purposes did the human brain evolve and why does it take so much of our physiological resources?
