Phys.org / Chromatin tracking reveals two motion modes that help control gene expression
Gene expression is controlled, in part, by the interactions between genes and regulatory elements located along the genome. Those interactions depend on the ability of chromatin—a mix of DNA and proteins—to move around within ...
Phys.org / A silent robot shadows sperm whales by listening to their clicks
An autonomous underwater glider is giving us a new and effective way to track sperm whales by tuning into their clicks and silently following them. To study these large oceanic predators, researchers need to monitor their ...
Phys.org / A simple filter swap could advance marine eDNA biomonitoring
Researchers at Aarhus University have demonstrated that a simple adjustment to water filtration methods can dramatically improve the detection of marine animal DNA when using advanced, PCR-free sequencing. This methodological ...
Phys.org / Saudi Arabia's water problem has a surprising solution: Its own wastewater
More than two-thirds of Saudi Arabia's irrigation water and a third of the country's drinking water comes from groundwater, yet aquifers are being depleted faster than they recharge. At the same time, sewage treatment generates ...
Phys.org / Hostage‑taking by rogue states is on the rise: New research provides fresh ways to tackle it
Hostage-taking by nation-states is emerging as an overlooked consequence of the more unstable and dangerous world that's been created by the fracturing rules-based order. In an increasingly might-is-right system of international ...
Medical Xpress / Study finds bariatric surgery less costly than GLP-1 drugs over time
A new real-world analysis of more than 90,000 patients with obesity and type 2 diabetes finds metabolic and bariatric surgery costs significantly less than weekly injections of GLP-1 drugs over a two-year period, according ...
