The new technology may help answer outstanding questions about the immune system, cancer, Alzheimer’s, and more.
(University of Sheffield) Radiocarbon dating is set to become more accurate than ever after an international team of scientists improved the technique for assessing the age of historical objects.
(University of Sheffield) Scientists from the University of Sheffield have used mathematical modelling to understand why flocks of long-tailed tits segregate themselves into different parts of the landscape.
Modelling the predicted movements of pervasive sap-sucking tiny insects before they infest banana crops has the potential to become a key tactic in the fight against a devastating virus, according to new research. Banana bunchy top virus (BBTV) is an aphid-transmitted banana disease that has been in Australia since 1913. Researchers have designed a model that tracked the probability of a banana plant being infected by aphids that carried the disease.
(University of Leeds) Glaciers in the Southern Alps of New Zealand have lost more ice mass since pre-industrial times than remains today, according to a new study led by the University of Leeds. The study mapped Southern Alps ice loss from the end of the Little Ice Age — roughly 400 years ago — to 2019. It found that relative to recent decades, the Southern Alps lost up to 77% of their total Little Ice Age glacier volume.
(Virginia Tech) D. Sarah Stamps, an assistant professor in the Department of Geosciences in the College of Science, has received a five-year Faculty Early Career Development (CAREER) Program grant worth $625,000 from the National Science Foundation (NSF) to investigate the role of volcanism in early phase continental rifting — the process in which two plates move apart and stretch the continental crust — at the Natron Rift in Tanzania.

(Cell Press) The Y chromosome has shrunken drastically over 200 million years of evolution. Even those who study it have used the word “wimpy” to describe it, and yet it continues to stick around. An Opinion paper publishing on August 6, 2020 in the journal Trends in Genetics outlines a new theory–called the ‘persistent Y hypothesis’–to explain why the Y chromosome may be more resilient than it first appears.
(Virginia Tech) Specifically, he pointed out that oilfield brine has much different properties, like density and viscosity, than pure water, and these differences affect the processes that cause fluid pressure to trigger earthquakes.
My views on climate change—and, more generally, on humanity’s future—have never been stable. Depending on what I’m reading, and perhaps shifts in my neural weather, I ricochet between optimism and dread. Last spring I was feeling pretty glum about, well, everything when iconoclastic…
