Rapid crevasse growth on Greenland Ice Sheet
Research shows that crevasses on Greenland’s Ice Sheet are growing at an alarming rate, potentially accelerating ice loss and sea level rise. The study, which used advanced digital elevation models to document crevasse volume changes from 2016 to 2021, underscores the need for continued monitoring to refine predictions of future ice sheet behaviour.

Squid pigments could transform solar technology
Researchers have discovered that pigments in squid chromatophores can convert light into electricity, potentially revolutionizing solar technology. The study found that these pigments, when exposed to sunlight, generate a charge that could be harnessed for energy.

Mesozoic mammals likely sported dark coats of fur
A study in Science by a team of paleontologists and biologists has found that mammals from the Mesozoic era likely had dark fur, an adaptation that possibly helped them avoid predators such as dinosaurs. By examining melanosome patterns in fossils, researchers developed a model indicating these mammals were small and nocturnal, akin to modern moles and voles.

Genes that influence brain aging
Scientists have identified 64 genes that influence the rate of brain aging, using brain scans and genetic data from nearly 39,000 UK Biobank participants. The study also highlights 13 potential drugs that target these genes and have been explored for anti-aging effects. “The findings are significant because they could pave the way for new treatments to keep the brain healthier longer,” says neuroscientist Agustín Ibáñez.
