Creating an artificial protein shell to combat COVID-19

During the first COVID-19 wave, when Saumitra Das and colleagues were sequencing thousands of samples every day to check for SARS-CoV-2 variants as part of INSACOG, the Government of India's genome surveillance initiative, ...

Virus multiplication in 3-D

For viruses to multiply, they usually need the support of the cells they infect. In many cases, only in their host's nucleus can they find the machines, enzymes and building blocks with which they can multiply their genetic ...

Understanding color at a nanoscale

Some of the most vibrantly colored creatures in the animal kingdom don't owe their amazing colors to pigment. Instead, they cover themselves with microscopic structures that fine tune the way they reflect light.

Printable, colorful camouflage with polymers

In nature, colors can serve as a form of communication, but they can also hide animals and plants, camouflaging them from sight. Researchers now report in ACS Applied Materials & Interfaces that they have developed polymers ...

Method speeds up time to analyze complex microscopic images

Cryo-electron tomography permits researchers to study in detail the microscopic structures inside of cells. Researchers who typically required a week of effort to dissect the 3-D structure of a single cell will now be able ...

Experiments may help assess risks posed by falling space rocks

Four years ago, a brilliant fireball streaked across the dawn sky over Russia, then fractured with the force of about 500,000 tons of TNT. The shock wave blew out windows and damaged thousands of buildings across several ...
