On the strictly protected island of Golem Grad in North Macedonia, the tortoises are destroying their own population. During prolonged courtship, aggressive males are exhausting the females and frequently pushing them off the cliffs. Consequently, there are now one hundred
Astronomers have employed the upgraded Giant Metrewave Radio Telescope (uGMRT) and the MeerKAT radio telescope to observe a galaxy cluster known as RXCJ0232–4420. Results of the new observations, published April 29 on the arXiv pre-print server, deliver important insights into
A University of Florida study has made a key discovery in understanding a disease that for over a century has plagued the white button mushroom—a nutrient-dense vegetable that is valued for its versatility and health benefits. The study is published in the journal
A key Atlantic Ocean current system that helps regulate the planet's climate could weaken more than expected by 2100, with potentially devastating consequences worldwide, a new study has found.
There is an old adage that goes, "you are what you eat," meaning that the food you consume helps build your body and fuel your mind. The same is true now as it ever was. When it comes to early humans, studying what they ate and how they obtained high-quality food, such as meat,
A global report into the chocolate industry has found that while some companies are improving their sustainability practices, many retailers are still failing to ensure transparent and accountable cocoa supply chains that would protect cocoa farming communities.
The Swedish government recently announced it was moving from the classroom use of digital devices back to physical books. It cited concerns over declining test scores and increasing screen time.
Until now, studying the genetic processes in cells required destroying them—making it impossible to observe these processes over extended periods of time. A team from the Technical University of Munich (TUM) and Helmholtz Munich has developed a new method to repeatedly obtain
Some clinicians are pushing to broaden testosterone use, but there is debate about its benefits and risks
A team at the University of Hong Kong has developed a new “super steel” that can survive the harsh conditions needed to make green hydrogen from seawater. The material uses an unexpected double-protection mechanism that resists corrosion far better than conventional stainless
Scientists at the University of Rochester pulled off a remarkable experiment: they transferred a longevity-related gene from the famously long-lived naked mole rat into mice, and the mice ended up healthier and lived longer. The special gene boosts production of a substance
Scientists have uncovered a striking brain difference linked to psychopathy: people with psychopathic traits were found to have a striatum — a brain region tied to reward, motivation, and decision-making — that was about 10% larger on average than those without such traits.
Scientists long assumed Venus’s harsh environment would quickly destroy artifacts from probe missions. But a new study makes a compelling case to the contrary
Here are some of the most fascinating facts about animal moms, from naked mole rats to giraffes and octopuses
India faces challenging heat waves each year, but few places endure conditions as searing as the country's western desert salt pans, where workers rely on simple techniques to survive almost unbearable temperatures.
Scientists have uncovered a hidden “stop-scratching” signal in the nervous system that tells your brain when enough scratching is enough. The discovery centers on a molecule called TRPV4, which acts like part of an internal braking system for itch relief. In experiments
Minuscule silicon wafers propelled by lasers could be used to steer light sails, helping them travel beyond the solar system
A colossal underwater volcano in the South Pacific may have revealed a surprising new weapon against climate change. After the 2022 eruption of Hunga Tonga–Hunga Ha’apai, scientists detected enormous amounts of formaldehyde in the atmosphere — a telltale sign that methane, one
Scientists have uncovered strong evidence that a major Atlantic Ocean current system tied to global climate is weakening. The slowdown has been detected across a vast region of the North Atlantic over nearly two decades. Since this ocean circulation helps regulate weather and
Scientists have uncovered a hidden Antarctic threat that could accelerate global sea level rise far faster than expected. Deep beneath floating ice shelves, long channels carved into the ice appear to trap warmer ocean water, dramatically speeding up melting from below. Even
Rebooting the gut microbiome with bacteria from youth may help stop aging-related liver damage and even prevent liver cancer, according to new research in mice. Older mice that received their own preserved youthful microbiome showed less inflammation, reduced DNA damage, and no
Researchers have developed a stem cell-based model of the human intestine that may transform how new IBD treatments are discovered. After testing thousands of compounds, they identified glycyrrhizin — a natural substance found in black licorice — as a promising
Many grocery shoppers know the routine: bring fruit and vegetables home, rinse them, dry them and hope they stay fresh long enough to be eaten. But fresh produce is delicate. Grapes shrivel, apple slices brown and berries can spoil quickly.
Scientists have taken a major step toward ultra-secure quantum communication by demonstrating a remarkably stable quantum encryption system that worked across more than 120 kilometers of optical fiber. Using tiny semiconductor quantum dots that emit single particles of light on
"When people think of extremists, they tend to think of neo-Nazis," said Francesco Campisi, a lecturer at Université de Montréal's School of Criminology. "But there are many other fringe groups that may not be violent yet can give rise to extremism."
A major obstacle may be standing in the way of the next generation of ultra-tiny computer chips. Researchers discovered that many promising 2D materials lose their advantages because an invisible atomic-scale gap forms when they are combined with insulating layers. That tiny
A single scoop of water from an Irish river has revealed evidence not only of Ireland's only frog species—as expected—but also signs of the dreaded B. dendrobatidis fungus, marking the first time this devastating amphibian disease has been spotted in the country and exposing a
New research from the Durham University Management and Marketing Department shows that misunderstandings between investors and founders are a major reason why social innovation ventures fail to grow. In many cases, they collapse altogether.
The mountain bongo has become the "ghost of the forest," hard to spot amid the dense shrubs due to its ability to camouflage.
Engineered microorganisms are widely used in industrial biotechnology and biopharmaceutical applications, including the production of biofuels, sustainable chemicals, and therapeutic compounds. However, concerns remain regarding the unintended environmental release and
How are cold air masses advancing in the United States connected to fertilizers carried by "flying rivers" from Africa that nourish the soils of the Brazilian Amazon? An article published in Geophysical Research Letters reveals an atmospheric connection between these distant
