Crayfish Brain May Offer Rare Insight Into Human Decision-making

Crayfish make surprisingly complex, cost-benefit
calculations, finds a University of Maryland study, opening the door to a new line of research that may help unravel the cellular brain activity involved in human decisions. The Maryland researchers concluded that crayfish make an excellent, practical model for identifying the specific neural circuitry and neurochemistry of decision-making. Currently, there's no direct way to do this in humans or other primates.

A 110-foot Concrete Bridge Withstands 8.0 Earthquake Simulation

After a succession of eight separate
earthquake simulations, a 110-foot long, 200-ton concrete bridge model at the University of Nevada, Reno, withstood a powerful jolting, three times the acceleration of the disastrous 1994 magnitude 6.9 Northridge, Calif., earthquake, and survived in good condition.

Numerous studies are documenting the growing effects of climate change, carbon dioxide, pollution and other human-related phenomena on the world's oceans. But most of those have studied single, isolated sources of pollution and other influences.

Aircraft Cause Precipitation, Hole-punch Clouds

As turboprop and jet aircraft climb or
descend under certain atmospheric conditions, they can inadvertently seed mid-level clouds and cause narrow bands of snow or rain to develop and fall to the ground, new research finds. Through this seeding process, they leave behind unusual "hole-punch clouds."

Luís Amaral, a professor at
Northwestern University, combined his love of soccer with his research team's computational skills to measure and rank the success of soccer players based on an objective measure of performance instead of opinion. The results of the study will be published June 16, 2010, in PLoS ONE, a journal published by the Public Library of Science.

Carbon Dioxide is the Missing Link to Past Global Climate Changes

Carbon dioxide
(CO2) is the missing ingredient in explaining the advent of ice ages in the Northern Hemisphere and why those cold epochs have caused changes in the tropics for the past 2.7 million years. In a paper in the journal Science, Brown University geologist Timothy Herbert and others analyzed ocean sediment cores and found a definitive link between ice ages and ocean surface temperatures in the tropics. They believe CO2 explains the link.
