Coffee linked to slower biological ageing among those with severe mental illness
New research from King’s College London finds that coffee consumption within the NHS recommended limit is linked to longer telomere lengths – a marker of biological ageing – among people with bipolar disorder and schizophrenia. The effect is comparable to roughly five years younger biological age.

Closest Temperate World Orbiting Quiet Star Discovered
A temperate Earth-sized planet has been discovered only 11 light-years from the Solar System by a team using ESO’s unique planet-hunting HARPS instrument. The new world has the designation Ross 128 b and is now the second-closest temperate planet to be detected after Proxima b. It is also the closest planet to be…

The Achilles Heel of the Coronavirus
SARS-CoV-2 is critically dependent on a special mechanism for the production of its proteins. A collaborative team led by a research group at ETH Zurich obtained molecular insights into this process and demonstrated that it can be inhibited by chemical compounds, thereby significantly reducing viral replication in…

Sampling at negative temperature
Summary : Inspired by the definition of temperature in statistical mechanics and the possibility for it to be below zero, we try sampling LLaMA at T = − 0.001 T=-0.001 T = − 0.001 . The results are maximally weird.
