Scientists at the University of Bonn have discovered that spiders experience distinct stages of sleep, including a REM-like state that shares surprising similarities with human sleep. During this stage, the spiders move their eyes and twitch their muscles, behaviors also associated with REM (rapid eye movement) sleep in humans and…
Some people have the brain changes associated with Alzheimer’s disease but never develop dementia. While others experience worsening memory and thinking problems, these individuals remain mentally sharp despite signs of the disease in their brains. Scientists have long struggled to explain why. Now, researchers at the Netherlands Institute for Neuroscience…
Seven studies from Mayo Clinic are revealing new details about senescent cells, often called “zombie” cells because they stop dividing but remain active in the body. These aging cells release inflammatory substances that can contribute to diseases associated with growing older. The research, published in Nature journals, was conducted by…
An archaeological site in the Jordan Valley is rewriting the timeline of early human migration. New research shows that ‘Ubeidiya is at least 1.9 million years old, placing humans in the region hundreds of thousands of years earlier than previously believed. The revised dating makes ‘Ubeidiya, alongside Dmanisi in Georgia,…
New research suggests that exercising just once or twice a week may be enough to maintain some of the blood pressure benefits gained from regular physical activity, at least over a short period. However, people who continue exercising three times weekly may experience larger and more sustained improvements. The findings,…
Scientists from the University of Oxford, Newcastle University, and Cambridge University Hospitals NHS Foundation Trust have uncovered a previously unexplained cause of inflammatory bowel disease (IBD). The discovery could change how doctors understand, diagnose, and treat certain forms of the condition. The findings indicate that IBD is not simply one…
Exercise does more than make the heart stronger. New research suggests it also physically reshapes the nerves that control the heart, revealing an unexpected difference between the left and right sides of the body. Scientists at the University of Bristol (UK) discovered that moderate aerobic exercise changes the structure of…
An international research team has revisited one of the oldest precisely dated records of a total solar eclipse, uncovering new details about how Earth’s rotation has changed over thousands of years. By combining historical geography with modern astronomical calculations, the scientists reconstructed an eclipse that occurred in 709 BCE and…
Scientists exploring the forests of Yunnan, China, have discovered an extraordinary giant fungus that is challenging previous assumptions about how large certain fungi can grow. The newly identified species, Dianjunus rex, produces upright reproductive structures that can reach 50 cm (20 inches) in height and weigh as much as 2.2…
Scientists have developed and tested the first three-dimensional thermal invisibility cloak, a device that can conceal objects from infrared cameras while protecting them from extreme temperatures. The breakthrough could lead to new ways to cool microchips, safeguard delicate electronics, and prevent equipment from being detected through its thermal signature. The…
Tiny magnetic structures called skyrmions could help pave the way for a new generation of computers that process information more like the human brain while using far less electricity. Although most people have never heard of skyrmions, these microscopic magnetic vortices may eventually play an important role in how computers…
A shipwreck off the coast of Turkey is the oldest shipwreck in the world, our team of archaeologists believes. There’s little left of the ship itself but based on clues from its cargo – including pottery vessels – a research team I was part of has tentatively dated the wreck…
An artificial intelligence model called REDMOD can identify extremely subtle changes in pancreatic tissue that may signal cancer long before the disease becomes visible to doctors or conventional imaging technology.
