Phys.org / Where was Baltica 616 million years ago? Paleomagnetic data offer revised answer
About 600 million years ago, the continents wandered Earth, yet to settle into their current positions. Their locations during the Ediacaran (as this time is called) have been tough for scientists to pin down. Earth's magnetic ...
Phys.org / 'Atomic snapshots' of proofreading enzyme could lead to better COVID-19 drugs
The closest-ever detailed look at a key enzyme inside the virus that causes COVID-19 could lead to more effective treatment of the disease. Nucleotide analogs are a common type of antiviral medication that mimic the genetic ...
Medical Xpress / Fish reveal four distinct sleep states, including three with eye movements
Humans and other mammals cycle through distinct sleep phases. One of them is easily recognized by the darting motion of the eyes behind closed lids, giving it its name: REM (rapid eye movement) sleep. This is the state in ...
Medical Xpress / RNA blood markers may reveal illness trajectory and treatment success within days
Scientists are developing a test which could one day be used to predict how a patient's illness will progress, and even how well they will respond to treatment. The international team, led by researchers at Imperial College ...
Phys.org / Cryo-EM imaging reveals how the body stops bleeding
For the first time, scientists at University of Leeds reveal a complex mechanism behind blood clotting. The findings, published in Science Advances, visualize a key component of blood clotting—platelet myosin—and how it is ...
Phys.org / Mathematical framework solves asteroid route planning exactly for first time
A new publication from Bielefeld University sets a benchmark in optimization research. Together with an international team, Professor Michael Römer from the Faculty of Business Administration and Economics has developed a ...
Medical Xpress / Hantavirus not like COVID: doctor treating patient in Netherlands
The hantavirus that has broken out on the cruise ship MV Hondius is much less transmissible than COVID, the head of the Dutch unit treating one of the patients told AFP Thursday.
Medical Xpress / What lies behind hereditary heart rhythm disorders

Medical Xpress / Over half of parents in England are pestered by their children to buy junk food while food shopping, survey suggests
A study using a nationally representative survey of parents in England, presented at the European Congress on Obesity (ECO 2026, Istanbul, Turkey, 12–15 May), reveals that over half (58%) of parents are frequently pestered ...
Phys.org / Burned stone, child's bones, and lost jewelry hint at prehistoric mining camp high in the Pyrenees
In the past, scientists thought that prehistoric peoples only traveled briefly through high-altitude mountain areas, rather than staying to take advantage of their resources. But new evidence suggests that, starting about ...
Phys.org / Decades of deep sea mining research show threat to seafloor creatures
There's increasing interest in deep-sea mining, but the impacts that this will have on the animals that live in the depths isn't fully understood. A new review led by our scientists is giving us our first insight into how ...
Medical Xpress / AI-generated images of depression depict more stereotypes and arouse greater stigmatization, study suggests
Images generated using artificial intelligence (AI) depict more stereotypes and stigmas around depression than images used by the media to illustrate the disease. This is the main conclusion of a study on the perception held ...
