Butterfly migration could be largest known
Millions of painted lady butterflies that fluttered into California's Central Valley in the last week of March could be just the advance guard of one of the largest migrations of the species on record, said Arthur Shapiro, a professor and an expert on butterflies at UC Davis.
Research team recreates ancient underwater concrete technology
A University of Colorado at Boulder professor and his colleagues have taken a page from the writings of an ancient Roman architect and built an underwater concrete pier in the manner of those set in the Mediterranean Sea 2,000 years ago.

Endangered Species Act provisions appear to benefit imperiled organisms
An analysis of the conservation status of 1095 species that have been protected under the US Endangered Species Act (ESA) indicates that those that have been given more protection under the act are more likely to be improving in status and less likely to be declining than species given less protection.
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.
