Saturn's surprise: NASA discovered an energy source and a basic molecule for life on Enceladus

In the new study, evidence for additional sources of chemical energy, much stronger and more diverse than methane production, was discovered: a group of organic compounds was found that were oxidized, and this points to many chemical pathways for the existence of potential life in the subsurface ocean of Enceladus, because oxidation helps to release chemical energy.

Survive with 0% battery: an immune system that drains the cell of energy has been discovered

The new system was discovered in bacteria - but is also used in corals, bees and others

Professor Hermona Sorek, one of the world's leading researchers of gene expression in the brain, was able to find, in collaboration with her research colleagues, a molecular mechanism that occurs in the brains of Alzheimer's patients, which does not occur in men and which explains the acceleration of cognitive deterioration in Alzheimer's patients

For the past hundred years, the chemical trichloroethylene [TCE] has been used in decaffeinated coffee, metal cleaners, and dry-cleaned clothes. The substance itself is known to be a carcinogen, it is associated with miscarriages, congenital heart disease and a fivefold increase in the incidence of Parkinson's disease

In the picture: an illustration of the arrangement of water molecules at temperatures around the freezing point, arranged around a single reference molecule. The white area shows the orderly and directional organization of the water density in the form of an "oyster", which results from the properties of the bonds between the hydrogen molecules. The orange color shows a "volume increase area", which a water molecule cannot penetrate, due to its structural characteristics. Source: IBM.

In the study, the scientists examined collisions that occur between the molecules. Collisions of atoms have been studied in the past, but atoms - according to classical physics - are spherical, while molecules have an elongated structure. The structure of a colliding body affects the way it will move after the collision. Will elongated molecules behave differently from spherical atoms? And is knowing their shape enough to predict the outcome of the collision? Illustration: pixabay.com.
