Research explores how grape pests sniff out berries

Female grape berry moths are the biggest insect threat to wine grapes in the eastern U.S. The moths lay their eggs on grapes and, once hatched, the larvae penetrate the skin, then eat and damage the fruit. But no one is quite ...

Fusion by strong lasers

Nuclear physics usually involves high energies, as illustrated by experiments to master controlled nuclear fusion. One of the problems is how to overcome the strong electrical repulsion between atomic nuclei which requires ...

Researchers measure wake of supersonic projectiles

Imaging technology has vastly improved over the past 30 years. It's been about that long since the flow coming off of the base of projectiles, such as ballistic missiles, has been measured. Researchers in the Department of ...

Chemists observe 'spooky' quantum tunneling

A molecule of ammonia, NH3, typically exists as an umbrella shape, with three hydrogen atoms fanned out in a nonplanar arrangement around a central nitrogen atom. This umbrella structure is very stable and would normally ...

Experiment measures velocity in 3-D

Many of today's scientific processes are simulated using computer-driven mathematical models. But for a model to accurately predict how air flow behaves at high speeds, for example, scientists need supplemental real life ...

The secret to sneaky float serves

A research team led by the University of Tsukuba studied the aerodynamics of a volleyball using a wind tunnel and hitting robot. They found that no matter the orientation of a standard ball, the pattern of panels presents ...
