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.
SpaceX said its Starship spacecraft was "healthy" as it orbited the Earth and on track to return Saturday to its Texas launch site, where Elon Musk's company was planning to "catch" the vehicle for the first time.
Some people are excellent at visualizing scenes and images in their head, while others can’t do it at all
SpaceX's attempt to recover its entire Starship back at the launch pad was thwarted when the booster fell into the Gulf of Mexico and exploded Friday, but the spacecraft still soared into orbit in its boldest test yet.
Yale researchers have discovered that certain prescription drugs, healthy diets, and exercise can measurably slow biological aging, while popular anti-aging supplements appear largely ineffective. Their analysis of 51 studies could transform how scientists evaluate anti-aging
A 5,000-year-old mystery surrounding the tombs of Egypt’s first kings has taken a disturbing turn. Scientists reexamining 46 ancient skulls discovered evidence of potentially fatal head injuries in 18, suggesting that at least 39% of those studied may have been deliberately
A study published in Frontiers in Sustainable Food Systems reveals that, although partnerships and institutional collaboration feature prominently in climate-oriented agricultural research, their relationship with the scaling of innovations is rarely explicitly documented. The
Smiling may not always make you happier, and new research suggests that forcing yourself to smile repeatedly could actually make you feel worse. In a University of Florida study involving more than 1,100 participants, researchers discovered that while a single artificial smile
Power electronic devices help control the flow of electricity and convert it into forms needed by different machines, such as electric vehicles, renewable energy systems and industrial equipment. Some electrical energy is lost as heat during this process, reducing efficiency
Scientists have captured electrons making seemingly impossible jumps across forbidden energy gaps in graphene, with some transitions occurring at a remarkable 100% probability. The breakthrough offers an unprecedented look at quantum behavior and could help unlock a new
National ground stops of this kind are exceedingly rare
