The idea of having living fungi cover your body might not be the most appealing thing in the world. But what if it was part of a clothing fabric that could change color, protect you from UV rays and even repair its own tears? Those are just some of the possibilities of a new
SpaceX's Starship super-rocket deployed operational next-generation Starlink satellites for the first time during its 13th flight test, which addressed snags that arose in the previous test.
Insect wings are bristling with senses, feeling the wind blowing and even tasting potential mates, but little was known about whether moth wings are equipped with a sense of smell. Sonja Bisch-Knaden and Bill Hansson from the Max Planck Institute for Chemical Ecology, Germany,
Lithium in drinking water is a widespread and persistent source of human exposure across Tribal communities in the Western United States, according to a new study from Columbia University Mailman School of Public Health. The findings document substantial regional variation in
Lake fly larvae plunge more than 200 meters into Lake Malawi each day to hide from predators, using tiny air sacs to control their depth. A rubber-like material called resilin lets them expand or shrink the sacs by changing their pH. Their toughness challenges a popular
When you pick up a gallon (3.8 liters) of milk at the store, the nutrients it contains may depend on both what's on the label and the time of year. A new study reports that omega-3 fatty acids are highest in milk labeled as organic grass-fed and lowest in conventionally
The actions of big business shape public health, so local authorities need to carefully consider how to govern their relationships with them.
Dreams are not random mental noise. A large study of more than 3,700 dream and waking reports found that what we experience during sleep is shaped by both our personalities and the world around us. Rather than simply replaying daily events, the dreaming brain mixes memories,
The way to make a plant grow more may be to take something away. Trimming a section off a plant gene raised rice harvests by up to 25% in new tests by University of Chicago scientists. The plants also showed a better tolerance for drought and heat.
In the increasingly polarized political realm, moderates may be viewed as disloyal by both conservatives and liberals when the opposing side seems threatening, according to research published in the Journal of Experimental Psychology.
Researchers scanned the ears of hundreds of marine mammals to deduce when pinnipeds evolved to hear well in both air and water.
Unsweetened sparkling water may offer a tooth-friendlier alternative to sugary soda, according to a small preliminary study tracking how different drinks change mouth acidity. Soda caused the strongest and longest drop in salivary pH, while sparkling water produced only a
Animals are constantly moving to find food, water, suitable habitats, mates and safe places to rest. Because moving requires substantial energy, animals often rely on various biological and behavioral strategies to reduce unnecessary costs while seeking available resources.
Early humans in England crafted a rare piece of elephant bone into a reusable hammer for sharpening stone tools nearly 500,000 years ago. The extraordinary find reveals that ancient toolmakers were resourceful, skilled, and capable of surprisingly advanced planning.
Black holes represent some of the most extreme environments in the universe. They are the sources of the strongest gravitational fields, allowing us to test Einstein's theory of general relativity to an extent impossible with small objects. But we are also reaching the limit of
There are countless cultures and societies around the world, spanning thousands of years. One thing they all have in common is that death is a part of everybody's life. Examining how different societies commemorate their dead can give archaeologists and anthropologists insight
Searching for extraterrestrial intelligence has so far primarily meant focusing on one particular type of signal—and that signal has normally been based on our own current cutting-edge technology. But what if that's the wrong way to look for signs of alien intelligence? What if
A new study published in Nature Physics reports the first direct experimental evidence of a Floquet topological state, a novel light-induced phase of matter that, until now, has existed only on paper and in simulations. Topological insulators can conduct electricity along their
It’s a key step in saving them from extinction The post Koalas Are Getting a Vaccine to Help With Their STD Problem appeared first on Nautilus .
One of the challenges of searching for technosignatures (i.e., signs that intelligent life somewhere in the universe has created technology) is understanding what to look for. Technology is a very broad area, and different types would show up as different features. One of the
The need for a national deer management strategy to manage the decline of native forests is highlighted in a new research paper published today in the New Zealand Journal of Ecology. Led by Te Whare Wānanga o Waitaha | University of Canterbury (UC) Emeritus Professor David
A new study has found that mass shootings and deaths by suicide in the United States share seasonal patterns, reaching their highest levels during summer months. Analyzing national data spanning 2014–2021, researchers observed consistent summertime peaks in both mass shootings
Magnetoreception is one of the most controversial animal senses. And several bee species might have it
Young Jupiter’s powerful magnetic field may have created a safe zone where several large moons could survive. Saturn lacked this protection, possibly explaining why Titan stands almost alone among its largest moons.
A virtual reality (VR) platform has given researchers new insights into how artificial light at night alters the way coral reef fish respond to predators. The study brings together, for the first time, the metabolic expertise of the University of Glasgow with an innovative

Eating within a shorter daily window may help protect certain thinking skills as people age. In a small six-month trial, older women who limited eating to about 8 to 9 hours a day performed better on planning and problem-solving tests than those who ate over 12 hours. Both
A controlled mouse study has provided direct evidence that inherited genetics can steer how cancer begins and evolves after DNA damage. The discovery could eventually help doctors better predict cancer risk and tailor screening and treatments to each patient.
NASA astronaut Chris Williams and two Roscosmos cosmonauts are back on Earth after spending 241 days aboard the International Space Station. Their journey covered more than 102 million miles and included 3,856 trips around the planet.
A U.S.-Russian space crew landed safely in the steppes of Kazakhstan on Sunday after an eight-month stint on the International Space Station.
The gigantic wildfire ravaging southwestern France has created an extremely dangerous "pyrocumulonimbus"—a phenomenon never before seen in the country—the spokesman for the country's National Firefighters Federation of France (FNSPF) told AFP.
On a boat off the coast of California, Sara Lesser gazes wistfully at dozens of dolphins playing in the vessel's wake. This summer, extreme heat is making such a scene increasingly rare.
Firefighters battled massive blazes tearing through forests across France and Spain on Monday, as authorities warned of a fresh heat wave set to engulf the scorched French wine-growing region around the major city of Bordeaux.
The fossilized spines of saber-toothed cats in the La Brea Tar Pits reveal evidence of an unexpectedly high prevalence of rare spinal nerve tumors, suggesting that the species became inbred just before extinction. These tumors, which cause significant pain and reduced limb
Remains pulled from the La Brea Tar Pits revealed deformed vertebrae and rare tumors, possible signs of inbreeding among now-extinct saber-toothed cats.
The northern highlands of Ethiopia are among Africa's oldest agricultural landscapes. Some of the world's most important crops originated here, particularly pulses and grains, including teff. Yet another crop has a less well-known history in Ethiopia's Tigray region: the
Imagine holding one of our most precise quantum devices at a fixed position outside a black hole. A Josephson junction—two superconductors separated by an ultrathin barrier—can turn a voltage into a quantum oscillation with extraordinary precision. Would intense gravity change
Northern Eurasia contains about 20% of the world's forests and plays a crucial role in mitigating climate change by absorbing atmospheric carbon dioxide, thereby acting as a major carbon sink. However, understanding the region's carbon sink is challenging because it is
Many molecules exist in two mirror-image forms—like left and right hands—that look identical but can behave very differently, especially in biological systems and pharmaceuticals. Distinguishing between these enantiomers (also called chiral molecules) is a longstanding
When an adult refuses to let an injustice pass—stands up to a bully or asserts their rights—we call it principle. When a 15-year-old retaliates to an insult thrown in a school corridor, risking detention, we call it a failure to think ahead. It's easy to ascribe this to a
By analyzing the data from NASA's Fermi gamma-ray space telescope, Chinese astronomers have investigated a recently identified millisecond pulsar known as PSR J0435+3233. As a result, they found that the pulsar exhibits gamma-ray pulsations. The discovery was detailed in a
In nature, the rarest ingredient can be the one that holds everything together. In a new article published in Trends in Ecology & Evolution, Dr. Erika C. Freeman of the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) in Berlin argues that a handful of scarce
The laws of thermodynamics state that heat naturally flows from hotter systems or regions to colder systems or regions until a state of thermal equilibrium is reached. This simple principle underpins the operation of numerous technologies, ranging from refrigerators to power
