A fruit fly starts buzzing around food at a picnic, so you wave your hand over the insect and shoo it away. But when the insect flees the scene, is it doing so because it is actually afraid? Using fruit flies to study the basic components of emotion, a new Caltech study reports that a fly's response to a shadowy overhead stimulus might be analogous to a negative emotional state such as fear—a finding that could one day help us understand the neural circuitry involved in human emotion. 

A family with Cornell University roots nearly 100 years old is helping the school's College of Agriculture and Life Sciences promote safe, high-quality foods well into the 21st century.

Quantum computers are in theory capable of simulating the interactions of molecules at a level of detail far beyond the capabilities of even the largest supercomputers today. Such simulations could revolutionize chemistry, biology and materials science, but the development of quantum computers has been limited by the ability to increase the number of quantum bits, or qubits, that encode, store and access large amounts of data.

Berkeley researchers develop breakthrough technique for non-invasive nano-scale imaging.

One of the barriers to using graphene at a commercial scale could be overcome using a method demonstrated by researchers at the Department of Energy’s Oak Ridge National Laboratory.

Since lasers were invented in 1960, they have penetrated countless scientific, industrial and recreational fields: from eye surgery to DVD players, from cutting steel to triggering ignition in missile stages.

Flushing wet wipes down the toilet might not be such a good idea.

Whether a close-up of a leafcutter ant, or a micrograph of the neurons derived from marmoset stem cells, or an MRI of the hidden pathways in the human brain, submissions to University of Wisconsin-Madison’s 2015 Cool Science Image Contest continue to put science and nature on eye-catching display.

Can't resist finishing that burger? Researchers are developing a compound that could help control appetite.

Losses of managed honey bee colonies were 23.1 percent for the 2014-2015 winter but summer losses exceeded winter numbers for the first time, making annual losses for the year 42.1 percent, according to preliminary results of the annual survey conducted by the Bee Informed Partnership (http://beeinformed.org), the U.S. Department of Agriculture (USDA) and the Apiary Inspectors of America.

DART co-inventor discusses the crazy things found on paper money since company first started looking at currency.

New technique developed at Brookhaven Lab makes self-assembly 1,000 times faster and could be used for industrial-scale solar panels and electronics.
