Deer keds—biting flies found across Europe, Asia, Africa and the Americas—use their eyes and flight to locate a host, typically deer, but occasionally humans or other mammals. Once they land, however, they shed their wings permanently and spend the rest of their lives crawling
Life exists because elements combine to form complex organic molecules. Astrochemistry studies this process, trying to understand how nature creates carbon-based molecules critical for life. One source for these types of molecules is the outflows emitted by protostars.
"Biodegradable" has become one of the most reassuring words in modern packaging. It appears on coffee cups, shopping bags and food containers, implying a promise: this product is better for the environment because nature will eventually take care of it.
Even though sugars are often framed as simple sources of energy, they also serve as structurally complex and functionally diverse molecules that mediate interactions between organisms. Among these, β-1,2-glucans, which are a class of glucose-based polymers, stand out for their
Scientists have uncovered how the interplay between cell shape and mechanical stress influences the orientation of stomata (microscopic pores on the leaf surface) during early plant development.
Supermassive black holes are the largest known black holes in the universe, sitting at the center of most large galaxies. They are sometimes described as cosmic monsters because they feed on surrounding gas and dust when they are active, as well as destroy anything that gets
How was iron produced 2,000 years ago in Senegal? A recent study at the Didé West 1 archaeological site, in the Falémé Valley in eastern Senegal, sheds light on an ancient iron production technique.
Discovering new catalysts is one of the central challenges in developing clean-energy technologies such as green hydrogen production. Yet catalyst discovery has traditionally remained confined within individual material families, limiting researchers' ability to transfer
Legal reforms designed to curb the abusive use of "SLAPPs" are insufficient to stop the rich and powerful trying to block freedom of speech, a new study warns. Measures in the U.S., U.K. and the EU to stop strategic lawsuits against public participation do not address the
Ancient Egyptians are often depicted wearing black eyeliner, known as kohl, which was stored in small containers. While kohl containers are typically found throughout Egypt and Sudan (Nubia), their presence beyond these areas is limited to only a handful of examples.
Scientists at Scripps Research have uncovered a molecular “switch” that appears to fuel the damaging brain inflammation seen in Alzheimer’s disease. They found that a protein called STING becomes chemically altered in a way that keeps the brain’s immune system stuck in
Melanoma may not become steadily more dangerous with age as scientists once assumed. In a surprising discovery, researchers found that cancer spread was lowest in young mice, surged in middle-aged mice, and then dropped again in very old mice. The key appears to be a special
Great apes appear to build friendships much like humans do. By studying grooming behavior, researchers discovered that chimpanzees and bonobos form close inner circles along with wider networks of weaker social connections. Chimpanzees focus on a few trusted partners and become
Millions of people in central Africa rely on wild meat for their nutrition, especially in rural areas around the Congo rainforest, the second largest tropical rainforest in the world. Here, meat from domestic animals is scarce due to poor national transport infrastructure,
Scientists have developed a solar desalination system that turns seawater into drinking water without creating environmentally damaging brine. Special laser-textured metal panels use sunlight to evaporate water while automatically moving salt deposits away from the working
Many soybean farmers use seeds treated with fungicides to ward off disease, but the profits from these increased yields might not offset the cost of the treatment in most cases, according to a study published in Scientific Reports by researchers at Penn State.
Researchers have developed a compact quantum detector that makes terahertz radiation much easier to detect. A specially designed metasurface funnels incoming energy into tiny active regions, greatly strengthening the electrical signal produced. The approach boosted efficiency
In a major advancement for decentralized health care and environmental monitoring, researchers at Kumamoto University have successfully developed a palm-sized, battery-powered spectrophotometer that matches the performance of massive commercial laboratory equipment. Published
Astronomers using the James Webb Space Telescope (JWST) have discovered a stellar bar in GN20, a massive galaxy seen just 1.5 billion years after the Big Bang. The new paper was submitted to the preprint server arXiv on May 14.
Few creatures inspire as much universal dislike as ticks. Though small, these parasites have an enormous impact on human and animal health. Each year, ticks spread viruses and bacteria that infect people, livestock, wildlife, and pets around the world. Scientists at the
France's weather service warned Saturday that strong storms could mark the end of a record-breaking heat wave blamed for a number of deaths across northern Europe.
‘Penguin’ decays from CERN’s latest Large Hadron Collider experiment hint at weird new physics
Daraxonrasib, which nearly doubled patients' survival time, fights the disease in a new way. It bear-hugs a cancer protein that drives cell growth.
A surprising new discovery suggests that tiny microbes living inside fish may be helping shape the chemistry of the world’s oceans. Scientists found evidence that bacteria in the guts of marine fish work alongside their hosts to produce calcium carbonate, a mineral that plays
Harwati clasped her hands and offered a prayer on the edge of a sludge lake on the Indonesian island of Java, as dozen of residents gathered to mark two decades since mud volcano eruptions began displacing thousands.
Scientists have uncovered a surprising navigation system in pigeons: iron-filled immune cells in the liver that may act like tiny magnetic sensors. Birds deprived of these cells struggled to find their way home under overcast skies, indicating they rely on Earth’s magnetic
Mosquito repellents are key to protecting ourselves from mosquito bites and the pathogens they might carry. The most widely used active ingredient in insect repellents is N,N-diethyl-meta-toluamide, commonly known as DEET.
Australian researchers have trained lab-grown brain cells on a silicon computer chip to play the nineties shooter game "Doom" and say they are just scratching the surface of what the neurons could be capable of doing.
Reports of an explosion from people across New England on Saturday afternoon sent police agencies and others scrambling to understand what caused a double boom that shook buildings in Massachusetts and Rhode Island.
Perhaps nothing better illustrates the flamingo's status as a newcomer to the Venetian Lagoon than the fact that the local dialect has no word for them.
It's not clear why the National Science Foundation may be limiting funding to certain U.S. universities
Losing weight may involve rewiring the gut and the brain at the same time. In a study of obese adults, an intermittent fasting-style diet led to significant weight loss, healthier metabolic markers, and notable shifts in gut bacteria. Brain scans also revealed changes in
A new study suggests fish oil may help reduce insulin resistance even in people who aren't obese. In diabetic rats, omega-3 supplementation improved blood sugar levels, cholesterol, and inflammation by shifting immune cells into a more anti-inflammatory mode.
A new race to the moon is emerging between the United States and China. Unlike fifty years ago, the goal is no longer just about landing and leaving, but establishing a base that allows for a sustainable presence and extended stays on the surface of our natural satellite. The
