The question of the causes of species extinction confronts science with complex tasks.

A combined experimental and computational study shows promising results for a new class of catalysts producing ammonia under mild conditions.

Researchers have developed an innovative technique to track microbes and understand the various ways they process soil carbon, findings that add to our knowledge of how bacteria contribute to the global carbon cycle.

Methane, a powerful greenhouse gas, can be captured and transformed into protein-rich feed for farmed fish -- an increasingly important food sector. A new analysis shows how to make the approach more cost-effective than current fish feeds.

Obesity, diabetes and gastrointestinal cancer are frequently linked to an unhealthy diet. However, the molecular mechanisms responsible for this are not fully understood. Researchers have gained some new insights that help to better understand this connection. These findings provide an important basis for the development of non-invasive therapies.

Phages are viruses that infect bacteria and can also be used to treat human infections. However, as with antibiotics, bacteria can readily evolve resistance to phage attack, highlighting a key limitation to the use of phages as therapeutics. Now, researchers have shown that the naturally occurring phage A1-1 kills Shigella flexneri, a major cause of dysentery in sub-Saharan Africa and southern Asia and selects for phage-resistant mutants with reduced virulence.

Puppyhood dietary factors may affect the onset of canine allergy and atopy related skin symptoms in adulthood, according to a new study.
