Cancer immunotherapy has been a game-changer, but many tumors still find ways to slip past the immune system. New research reveals a hidden trick: cancer cells can package the immune-blocking protein PD-L1 into tiny particles that circulate through the body and weaken
When astronomers look out into the cosmos, they see supermassive black holes (SMBH) in two different states. In one state, they're dormant. They're actively accreting only a tiny amount of matter and emit only faint, weak radiation. In the other, they're more actively accreting
New U.S. dietary guidelines promote eating full-fat foods and meats. But experts say nuts and seed oils are better sources of the two crucial fats we need.
A massive international study of more than 3,100 long COVID patients uncovered a striking divide in how brain-related symptoms are reported around the world. In the U.S., the vast majority of non-hospitalized patients described brain fog, depression, and anxiety, while far

Using various space telescopes and ground-based facilities, astronomers have performed X-ray and radio observations of an accreting millisecond X-ray pulsar known as MAXI J1957+032. Results of the observational campaign, published on the arXiv preprint server and forthcoming
Charge density waves (CDWs) are ordered, crystal-like patterns in the arrangement of electrons that spontaneously form inside some solid materials. These patterns can change how electricity flows through materials, in some cases prompting the emergence of superconductivity or
A comic about humanity’s love letter to interstellar space The post Ann Druyan on How NASA’s Golden Records Got Made appeared first on Nautilus .
Where your body stores fat may matter just as much as how much you carry—especially for your brain. Using advanced MRI scans and data from nearly 26,000 people, researchers identified two surprising fat patterns tied to faster brain aging, cognitive decline, and higher
A new species of amphibian that lived 150 million years ago has been discovered in Portugal. The tiny animal was one of the earliest species belonging to a mysterious group of amphibians that lived from the time of the dinosaurs right up until the last Ice Age.
Mangrove forests play an important role in the global carbon cycle, particularly within the marine carbon system. Growing along tropical and subtropical coastlines, these salt-tolerant trees are among nature's most efficient "blue carbon" sinks, capturing and burying vast

Brazil has declared the acai berry a national fruit, a move to stamp its ownership on the popular "superfood" as concerns grow about foreign companies staking claims to the Amazon's biological riches.
Australian authorities have sparked a backlash by killing a group of dingoes linked to the death of a young Canadian woman on an island in the country's east.
Thailand has given a contraceptive vaccine to wild elephants for the first time in an effort to control their ballooning population, a conservation official said on Wednesday.
A volcano in Russia's far east on Wednesday spewed ash several kilometers into the sky, authorities said, putting on a spectacular display in its latest eruption.
Using a superconducting quantum computer, physicists created a large and complex version of an odd quantum material that has a repeating structure in time
Drinking tea, particularly green tea, is linked to better heart health, improved metabolism, and lower risks of chronic diseases like diabetes and cancer. It may also help protect the brain and preserve muscle strength as people age. However, processed teas—such as bottled and
Mark Thomson, the new head of Europe's physics laboratory CERN, voiced confidence Tuesday about raising the billions of dollars needed to build by far the world's biggest particle accelerator.
A NASA research plane malfunctioned and had to touch down in Texas without landing gear on Tuesday, sliding across the runway on its belly and sending plumes of flame behind it, a video posted to social media showed.
A 77-pound mountain lion set off a scramble Tuesday as it wandered through San Francisco's wealthy Pacific Heights neighborhood before finally being captured as onlookers safely peered from their home windows or stood across the street.
AI may learn better when it’s allowed to talk to itself. Researchers showed that internal “mumbling,” combined with short-term memory, helps AI adapt to new tasks, switch goals, and handle complex challenges more easily. This approach boosts learning efficiency while using far
Research in the Journal of Applied Ecology has identified threats to endangered plants in an urban area, generating information that can be used to guide effective conservation strategies across major cities. Investigators in Germany analyzed data on 1,231 populations of 201
A repeating fast radio burst has just given up one of its biggest secrets. Long-term observations revealed a rare signal flare caused by plasma likely ejected from a nearby companion star. This shows the burst source isn’t alone, but part of a binary system. The finding
For the first time, astronomers have captured radio signals from a rare exploding star, exposing what happened in the years leading up to its death. The radio waves reveal that the star violently shed huge amounts of material shortly before it exploded, likely due to
What looked like a pearl necklace on a tiny spider turned out to be parasitic mite larvae. Scientists identified the mites as a new species, marking the first record of its family in Brazil. The larvae attach to juvenile spiders and feed on lymph through a weak spot in the
Donkeys are an unassuming yet ubiquitous presence in northern Namibia. They traverse sandy village roads, pull carts stacked with firewood, and graze freely along the northern edge of Etosha National Park.
A sweeping scientific review highlights wild blueberries as a standout food for cardiometabolic health. The strongest evidence shows improvements in blood vessel function, with encouraging signs for blood pressure, cholesterol, blood sugar, gut health, and cognition.
A common parasite long thought to lie dormant is actually much more active and complex. Researchers found that Toxoplasma gondii cysts contain multiple parasite subtypes, not just one sleeping form. Some are primed to reactivate and cause disease, which helps explain why
Human-induced climate change made the intense early January heat wave in Australia five times more likely, according to a new analysis by World Weather Attribution.
Recent research has demonstrated that a rhodium (Rh) cluster of an optimal, intermediate size—neither too small nor too large—exhibits the highest catalytic activity in hydroformylation reactions. Similar to the concept of finding the "just right" balance, the study identifies
There's a bright side to every situation. In 2032, the moon itself might have a particularly bright side if it is blasted by a 60-meter-wide asteroid. The chances of such an event are still relatively small (only around 4%) but are non-negligible. And scientists are starting to
Artificial intelligence is reshaping how companies operate, but it may not translate into more job creation, according to new research.
When Apollo 13 looped around the moon in April 1970, more than 40 million people around the world watched the United States recover from a potential catastrophe. An oxygen tank explosion turned a planned landing into an urgent exercise in problem-solving, and the three
Engineering can create weapons systems or systems for defense and well-being. But can engineering create peace? In a Perspective, Guru Madhavan and colleagues propose an expansive mode of engineering practice that seeks to reduce conflict. The work is published in PNAS Nexus.
Gifu University scientists have uncovered how a brain-specific enzyme reshapes protein-linked sugar chains to facilitate the formation of complex glycans essential for normal brain function. These insights could inform future research into glycan-related brain disorders and
Shortly after her arrival last fall, Amelia Gray met Hudson, and the pair hit it off immediately. They touched their noses together in greeting and chuffed—a soft, breathy, snorting sound that signals affection or reassurance. Amelia Gray rolled on her back, gently pawing at
EPFL professor Robert West and invited professor Ágnes Horvát discuss how the rise of AI is transforming the dissemination and production of scientific knowledge.
Moths move significantly less when exposed to artificial nighttime light, new research shows. Moths' attraction to artificial light, such as streetlights, is common knowledge and has been much studied. But, as many people will have observed, moths may also remain still if they
