Accurate protein structure prediction now accessible to all

Posted: 15 Jul 2021 11:23 AM PDT

Protein design researchers have created a freely available method, RoseTTAFold, to provide access to highly accurate protein structure prediction. Scientists around the world are using it to build protein models to accelerate their research. The tool uses deep learning to quickly predict protein structures based on limited information, thereby compressing the time for what would have taken years of lab work on just one protein. Predicting intricate shapes of proteins vital to specific biological processes could speed treatment development for many diseases.

Scientists take snapshots of ultrafast switching in a quantum electronic device

Posted: 15 Jul 2021 11:23 AM PDT

Scientist demonstrated a new way of observing atoms as they move in a tiny quantum electronic switch as it operates. Along the way, they discovered a new material state that could pave the way for faster, more energy-efficient computing.

Unlocking efficient light-energy conversion with stable coordination nanosheets

Posted: 15 Jul 2021 09:45 AM PDT

Two-dimensional 'nanosheets' made of bonds between metal atoms and organic molecules are attractive candidates for photoelectric conversion, but get corroded easily. In a new study, scientists present a new nanosheet design using iron and benzene hexathiol that exhibits record stability to air exposure for 60 days, signaling the commercial optoelectronic applications of these 2D materials in the future.

Hollow nano-objects made of DNA could trap viruses and render them harmless

Posted: 15 Jul 2021 07:30 AM PDT

To date, there are no effective antidotes against most virus infections. Scientists have now developed a new approach: they engulf and neutralize viruses with nano-capsules tailored from genetic material using the DNA origami method. The strategy has already been tested against hepatitis and adeno-associated viruses in cell cultures. It may also prove successful against corona viruses.

Fluorescence lighting helps detect impurities in water

Posted: 15 Jul 2021 06:08 AM PDT

Shining a beam of light into potentially contaminated water samples may hold the key to real-time detection of hydrocarbons and pesticides in water. Researchers are testing the use of fluorescence to monitor water quality. The results, they say, show great promise.

Repairs using light signals

Posted: 15 Jul 2021 06:08 AM PDT

Repairing complex electrical appliances is time consuming and rarely cost-effective. The working group has now developed a smart microparticle that enables defective components in these appliances to be identified more quickly and easily by using light signals. In the long-term, this could make repairs easier and extend the operating life of devices.
