How bacteria recognize viral invasion and activate immune defenses

There's no organism on Earth that lives free of threat—including bacteria. Predatory viruses known as phages are among their most dire foes, infiltrating their cells to replicate and take over. Bacteria have evolved an ...

Fatty acid factory filmed at work

Humans generally ingest most of their required fatty acids through their diet. Still, fatty acid biosynthesis is a vital metabolic pathway. For yeasts and bacteria, it is even indispensable.

New ammonia reaction could offer a sustainable source of nitrogen

A big goal in chemistry is to find a simple way to produce amines from ammonia and unsaturated hydrocarbons. Catalytic addition to activate and transfer ammonia would not give rise to any waste. Hence, the process would be ...

Scientists close the cycle on recycling mixed plastics

Little of the mixed consumer plastics thrown away or placed in recycle bins actually ends up being recycled. Nearly 90% is buried in landfills or incinerated at commercial facilities that generate greenhouse gases and airborne ...

An electrical switch to control chemical reactions

New pharmaceuticals, cleaner fuels, biodegradable plastics: in order to meet society's needs, chemists have to develop new synthesis methods to obtain new products that do not exist in their natural state.
