Breaking COVID-19's 'clutch' to stop its spread

The virus that causes COVID-19 uses a clutch-like shifter to enable transcription of one RNA string into multiple proteins, and therein lies a vulnerability. A proof-of-concept study shows it's possible to eliminate that shifter with an RNA-binding compound linked to a 'trash this' signal.

Passive email rudeness may create problems for employees' sleep, which further puts them in a negative emotional state the next morning, thus creating a vicious cycle.

The surprising organization of avian brains

Some birds can perform amazing cognitive feats - even though their forebrains seem to just consist of lumps of grey cells, while mammalian forebrains harbour a highly complex neocortex. A study reveals for the first time amazing similarities between the neocortex of mammals and sensory brain areas of birds: both are arranged in horizontal layers and vertical columns.

Theoretically, two layers are better than one for solar-cell efficiency

Solar cells have come a long way, but inexpensive, thin film solar cells are still far behind more expensive, crystalline solar cells in efficiency. Now, a team of researchers suggests that using two thin films of different materials may be the way to go to create affordable, thin film cells with about 34% efficiency.
