The molecules, while not a direct sign of life, still signal the existence of complex chemistry on the Red Planet.

Three long-chain alkanes detected by Nasa’s Curiosity rover could be chemical biosignatures that point to a history of past ...

This important study shows that the Nora virus, a natural Drosophila pathogen that also persistently infects many laboratory fly stocks, infects intestinal stem cells (ISCs), leading to a shorter life ...

Abiotic stresses such as heat, drought, salinity, and intense light significantly impact plant productivity in varying ...

How plants perceive and respond to heat stress via chloroplast is obscure. Here, the authors present evidence that an RNA editing component undergoes heat-dependent condensation, which in turn ...

Though this discovery doesn’t constitute definitive proof of life, the complexity of these molecules is significant. The ...

A discovery in the deserts of Namibia, Oman, and Saudi Arabia has opened new doors in the world of geomicrobiology.

Researchers caution that the molecules could be of abiotic or biological origin, and do not represent definitive proof of ...

The word comes from the Greek “phaino” (to show or appear) and “logos” (to study). Phenology works because certain events ...

A project that aims to use kelp extracts to manage nutrients more efficiently is underway with a partnership of experts ...

Mysterious micro-burrows in desert marble and limestone were probably made by microbes that lived millions of years ago.

Experts have found long carbon chains, containing up to 12 consecutive atoms, in samples of Martian rock which date back ...
