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 ...

Plan B for cholesterol transport

Cholesterol is a vital cell building block in humans and animals, and an integral part of the so-called cell membrane. This boundary layer separates the interior of the cell from the neighboring cells and the surrounding ...

Accelerating development of STT-MRAM

Researchers at the Center for Innovative Integrated Electronic Systems (CIES) at Tohoku University have successfully observed microscopic chemical bonding states in ultrathin MgO—an important determinant in STT-MRAM performance. ...

New protein-sensing mechanism discovered

In a stunning discovery, molecular biologists from the University of Konstanz and ETH Zurich have been able to demonstrate that the nascent polypeptide-associated complex (NAC) senses newly synthesized proteins upon birth ...
