The trust game: Measuring social interaction
If trust is a two-way street, then researchers at Baylor College of Medicine have mapped where in the brain that trust is formulated and how the decision to trust shifts with experience.
In a report in this week's Science, Dr. P. Read Montague Jr. and colleagues at the BCM Human Neuroimaging Laboratory and California Institute of Technology describe where and when trust is formed between two anonymous people interacting via functional magnetic resonance imaging machines more than 1,500 miles apart.

Legendary Siberian tiger, Olga, killed by poachers
Olga, the first Siberian tiger ever fitted with a radio-collar, is dead, according to officials from the Bronx Zoo-based Wildlife Conservation Society, who have been tracking the big cat for the past 13 years. The 14-year-old tiger, missing since January, is presumed killed by poachers who destroyed her radio collar.

Ecologist plays critical role in first global ecosystem study
Up to 60 percent of "ecosystem services" that support life on earth, such as food, water and climate regulation, are crumbling at an unsustainable rate, members of the Millennium Ecosystem Assessment (MA) project report here today (March 30). Designed to assist global policy-makers, MA is the first international study to appraise the status of Earth's diverse ecosystems and their associated impact on human well-being.

Carrots of color
In a Texas A&M University processing room, yellow carrots were stacked up against maroon, red and orange carrots for strenuous tests to see which would make it to the next step in breeding. Dr. Leonard Pike, Texas Agricultural Experiment Station plant breeder, appreciates the novelty of colored carrots, but he's also interested in the phytochemicals packed in each carrot. He hopes to breed one carrot with all the good compounds, regardless of color.

Changes in Earth's tilt control when glacial cycles end
Scientists have long debated what causes glacial/interglacial cycles, which have occurred most recently at intervals of about 100,000 years. A new study reported in the March 24 issue of Nature finds that these glacial cycles are paced by variations in the tilt of Earth's axis, and that glaciations end when Earth's tilt is large.

'You can't buy conservation,' suggests survey of Africa's rain forest parks
Economic assistance to areas surrounding Africa's rain forest parks does not, as currently applied, contribute to their health, suggests an extensive survey of park scientists and managers. Rather, the survey found the most successful parks are those with public support and strong law enforcement. The survey's authors also said that their findings indicate that careful ecological and compliance monitoring and stable long-term funding are key to park success.

Underwater robot launched from Bermuda to cross Gulf Stream
A small autonomous underwater vehicle, or AUV, named Spray was launched yesterday about 12 miles southeast of Bermuda. The two-meter-(6-foot)-long orange glider with a four-foot wingspan will slowly make its way northwest, crossing the Gulf Stream and reaching the continental shelf on the other side before turning around and heading back to Bermuda, where it will be recovered in July.

Elephants imitate sounds as a form of social communication
Elephants learn to imitate sounds that are not typical of their species, the first known example after humans of vocal learning in a non-primate terrestrial mammal. The discovery, reported in today's Nature, further supports the idea that vocal learning is important for maintaining individual social relationships among animals that separate and reunite over time, like dolphins and whales, some birds, and bats.

Octopuses occasionally stroll around on two arms, UC Berkeley biologists report
In an eerie reprise of what it may have been like when humans first raised their arms and walked on two feet, films taken by a UC Berkeley biologist show that octopuses sometimes pick up six of their arms and scoot along on the outer ends of the other two. One Indonesian octopus resembles a tiptoeing coconut, while a second looks like algae scooting along on conveyor belts.
