Neural network helps design brand new proteins

With their intricate arrangements and dynamic functionalities, proteins perform a plethora of biological tasks by employing unique arrangements of simple building blocks where geometry is key. Translating this nearly limitless ...

Enhanced arsenic detection in water, food, soil

It is a cruel paradox that on a planet with a surface mostly covered by water, hundreds of millions of people don't have access to clean drinking water. As for the pollution of potable and natural water sources, one of the ...

New type of bolometer detector for far-infrared telescopes

To study how stars and planets are born we have to look at star cradles hidden in cool clouds of dust. Far-infrared telescopes are able to pierce through those clouds. Conventionally, niobium nitride bolometers are used as ...

Low-cost disease diagnosis by mapping heart sounds

Aortic valve stenosis occurs when the aortic valve narrows, constricting blood flow from the heart through the artery and to the entire body. In severe cases, it can lead to heart failure. Identifying the condition can be ...

Harvesting resources on Mars with plasmas

An international team of researchers came up with a plasma-based way to produce and separate oxygen within the Martian environment. It's a complementary approach to NASA's Mars Oxygen In-Situ Resource Utilization Experiment, ...

Density-near-zero acoustical metamaterial made in China

When a sound wave hits an obstacle and is scattered, the signal may be lost or degraded. But what if you could guide the signal around that obstacle, as if the interfering barrier didn't even exist? Recently, researchers ...

Simulations improve understanding of crystalline HMX explosives

Computer simulations exploring the effects of shock waves on crystalline HMX, performed by Ryan Austin, a staff scientist in Engineering's Computational Engineering Division, and a team of LLNL researchers, are featured on ...

New electronic paper could make inexpensive electronic displays

Researchers from the University of Tokyo have revamped an old e-paper concept to make an inexpensive handwriting-enabled e-paper well suited to large displays like whiteboards. They describe the e-paper in the Journal of ...

The microscopic topography of ink on paper

A team of Finnish scientists has found a new way to examine the ancient art of putting ink to paper in unprecedented 3-D detail. The technique could improve scientists' understanding of how ink sticks to paper and ultimately ...
