Johns Hopkins scientists have uncovered hidden warning signs of Alzheimer’s disease that may appear up to a decade before memory loss begins. Brain scans revealed that two regions involved in memory and emotion start shrinking before the hippocampus, the area doctors typically
A groundbreaking drone survey has revealed a startling split in the fate of New Zealand's endangered Erect-crested penguins. While one population has remained stable for decades, another has declined by more than 40%, apparently due to a combination of predators, worsening
Dinosaurs may have been snacking on seaweed and other ocean foods more than 100 million years ago, according to surprising new evidence hidden in their fossilized teeth. Researchers discovered chemical signatures suggesting that coastal dinosaurs and other prehistoric animals
Scientists have discovered how to use flashes of laser light to organize tiny electrical regions inside a crystal, solving a decades-old mystery about how the material behaves. The laser-induced alignment lasts just a trillionth of a second, but the breakthrough could open the
ESA’s Euclid space telescope has discovered 31 ancient quasars, including two record-breaking objects that shone with the brightness of a trillion Suns when the Universe was just 670 million years old. Powered by supermassive black holes, these extraordinary cosmic beacons
On April 10, 2019, the Event Horizon Telescope (EHT) Collaboration revealed the first picture of a black hole. The object is at the center of a galaxy known as M87, about 55 million light-years away.
Scientists have uncovered a hidden warning sign in routine heart scans that could predict sudden cardiac death before it strikes. The AI-powered discovery outperformed conventional screening methods, potentially revealing thousands of people at risk of a fatal heart malfunction
The advance of urbanization in the São Paulo Metropolitan Area in Brazil is causing the collapse of food webs in local streams. A study published in August in the journal Nature Cities reveals that the impact of the metropolis goes far beyond a simple reduction in species.
Since 2022, astronomers have been puzzling over a new kind of cosmic object called long-period radio transients. These are objects that emit bright flashes of radio waves into space every few minutes to every few hours. Some have been traced back to binary systems consisting of
Today, Old Dongola is an abandoned settlement on the banks of the Nile in northern Sudan. Hundreds of years ago, however, this place looked very different.
NASA's Voyager 1 is about to become humanity's first object to reach one light-day from Earth as it pushes ever deeper into interstellar space.
Thanks to the gravitational lensing caused by a massive galaxy cluster and high-resolution images from the James Webb Space Telescope (JWST), astronomers discovered an exploding star when the universe was 4.9 billion years old. The discovery paper, posted to the arXiv preprint
Earth is approximately 4.5 billion years old, according to estimates. However, rocks dating back to the planet's earliest days are extremely rare. Hence the excitement over the discovery in northern China of some of the oldest known rocks on Earth, dating back 3.95 billion
"It isn’t clear that ice baths really are the best way to recover post exercise"
Lake Baikal in Siberia holds around 20% of the world's surface freshwater, making it the most voluminous freshwater lake (Lake Superior on the United States–Canada border is the largest by surface area). This makes the lake one of the most important environments for
Leaving Madagascar with smaller pollinators The post Giant, Fruit-Eating Bats Are Shrinking appeared first on Nautilus .
How unequal were prehistoric societies? And how can archaeologists measure wealth in cultures that left behind no written records, no tax registers and no census data?
The images are part of Euclid’s first major data release
In propulsion system design, engineers have long faced a trade-off between solid and liquid rocket fuels. Each has advantages and disadvantages, and in an effort to try to min/max the efficacy of different types of fuel, researchers have long placed an emphasis on a hybrid
A landmark study proposes a new way to identify people whose excess body fat is affecting their health
There was a time when Earth didn’t have plate tectonics The post A Chemical Fingerprint in Ancient Rocks Suggests Plate Tectonics Began 2.5 Billion Years Ago appeared first on Nautilus .
A simple change to your daily routine could make a surprising difference in how you feel, both physically and mentally. University of Missouri researchers found that older adults who followed consistent daily schedules reported less physical pain and fewer symptoms of
Scientists have developed a promising new fiber supplement that improves gut health in people with irritable bowel syndrome (IBS) without worsening bloating, pain, or other digestive symptoms. The specially designed blend also improved gut-related anxiety and produced
Stanford researchers have discovered that hidden patterns of brain activity can predict Alzheimer’s risk years before memory problems appear, potentially offering an earlier warning than traditional biomarkers. The same patterns also reveal which brains are unusually resistant
A new study suggests that the right kind of exercise could help protect young adults from early knee osteoarthritis following ACL surgery. Researchers found that a four-month supervised rehabilitation program improved pain, muscle strength, and quality of life without damaging
In his Alaskan community, fisherman Bob Candopoulos has long welcomed tourists to his business that's showcased by a sign featuring a king salmon.
Screwworm, which can devastate livestock, was eliminated from the U.S. in 1966. Now they’re back and the same old technique won’t be enough to get rid of them
Astronomers have uncovered a potentially enormous new dwarf planet beyond Pluto, hidden for years in one of the most crowded regions of the night sky. The discovery of 2026 ED138 could expand the solar system's official dwarf planet family and hints that more mysterious worlds
Scientists have developed an efficient method to transform used coffee grounds into a potential source of biodiesel while preserving the leftover material for other renewable fuels and valuable chemicals. The discovery could turn millions of tons of discarded coffee waste into
California was bracing Friday for a storm series packing heavy rain and surf that could once again flood coastal communities and potentially send monster waves pounding shores.
