Glaciers look still — but in reality they are constantly moving as they slowly carry ice from high mountains to the lower reaches. A new study has reported that glaciers in the Zanskar region of Ladakh are now moving more slowly than they did 30 years ago, offering new clues about how climate change is…

The story so far: Theoretical physicist Deepak Dhar has been awarded the Dirac Medal for his contributions to statistical physics — an honour he is sharing with three other physicists, Bernard Derrida, Marc Mézard, and Haim Sompolinsky. The Dirac Medal is awarded by the International Centre for Theoretical Physics (ICTP) in Trieste, Italy, on the…

As the immune system ages, it enters a state of chronic, low-grade inflammation called ‘inflammaging’. In the brain, inflammaging is especially damaging. Immune cells that normally clear toxic amyloid-beta, a protein that can clump together to form the plaques characteristic of Alzheimer’s disease, instead become dysfunctional, fuelling the neuroinflammation that drives the disease. So a…

When daytime photons, which are rich in blue light, enter the retina, they ‘activate’ cells containing melanopsin. | Photo Credit: Ron Lach/Pexels — Sahitya Agrawal, Raxaul A: The brain’s biological clock is a network of genes and proteins whose concentrations rise and fall in a roughly daily cycle. There is a cluster of neurons in…

The findings of a new study imply that genome-wide association studies — an increasingly popular kind of study that looks for the genetic variants linked to diseases — may be missing a significant fraction of heritable variation because that variation is not in the sequence Source link
