Scientists have transformed RNA, a biological molecule present in all living cells, into a biosensor that can detect tiny chemicals relevant to human health. Research by scientists centers on RNA, a ...

A team of scientists just discovered the longest organic molecules yet seen on Mars ... or they are the organic remnants of an ancient martian biology,” said Daniel Glavin, a senior scientist ...

Scientists find the protein IL-17 that fights infection also acts on the brain, inducing anxiety or sociability. This adds to evidence that immune molecules can influence behavior during illness.

In a single cell, around 1,000 RNAs, proteins and other molecules can be exchanged between the nucleus and the cytoplasm each second 2. This exchange is regulated by a large protein complex called ...

Scientists probed an existing rock sample inside Curiosity's Sample Analysis at Mars (SAM) mini-lab and found the molecules decane, undecane, and dodecane. These compounds, which are made up of 10 ...
