Probing proteins in single cells

Different cells make different proteins, and knowledge of these differences could greatly enhance scientists' understanding of the roles of individual cells in healthy tissues and in disease. But obtaining enough protein ...

Extreme environments provide clues to extraterrestrial life

Over the past decade, the NASA Astrobiology Institute funded Michigan State University geomicrobiologist Matt Schrenk's lab to study life in the extreme environment of groundwater in a highly alkaline aquifer near Lower Lake, ...

Fish are being increasingly exposed to endocrine disrupters

Microplastics, owing to their chemical properties, can carry micropollutants into a fish's digestive system where they are subsequently released through the action of its gastric and intestinal fluids. EPFL scientists, working ...

Some of the world's oldest rubies linked to early life

While analyzing some of the world's oldest colored gemstones, researchers from the University of Waterloo discovered carbon residue that was once ancient life, encased in a 2.5 billion-year-old ruby.

Warm milk makes you sleepy—peptides could explain why

According to time-honored advice, drinking a glass of warm milk at bedtime will encourage a good night's rest. Milk's sleep-enhancing properties are commonly ascribed to tryptophan, but scientists have also discovered a mixture ...

Improved fluorescent amino acids for cellular imaging

New research conducted by researchers in the lab of Penn's E. James Petersson in collaboration with Oregon State University and the University of Washington describes how proteins in living cells can be engineered to include ...
