Good news, everyone!

A protein lurking around in the blood can help with the accurate diagnosis of Alzheimer's disease. In a recent study, researchers from Spain investigated how blood-based biomarkers, such as a protein called p-tau217, affect both the clinical diagnosis of Alzheimer's and neurologists' confidence in their diagnosis.

Hydrogen fuel is a promising alternative to fossil fuels that only emits water vapor when used and could thus help to lower greenhouse gas emissions on Earth. In the future, it could potentially be used to fuel heavy-duty transport vehicles, such as trucks, trains, and ships, as well as industrial heating and decentralized power generation systems.

Researchers in Belgium have unveiled a striking chemical reaction in which ripples along a frozen reaction front resemble the rays of a shining star. Publishing their results in Physical Review Letters, Anne De Wit and colleagues at the Université Libre de Bruxelles have shed new light on the patterns that emerge in reaction–diffusion systems, offering fresh insight into how similar structures arise in the natural world.

Researchers at the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) have used long-term data from the Spree River to discover that aquatic plants can compensate for declining water levels in a drier climate. In recent summers, the growth of aquatic plants in the lower part of the Spree has led to an increase in water levels compared to previous years, thus compensating for the declining discharge.

Staying fit and active has long been associated with better heart and overall health. It might also improve the chances of survival for people with some forms of cancer. A study published in the journal JAMA Network Open reports that staying active is linked to longer survival after a cancer diagnosis, including in people with bladder, kidney and lung cancers.

The Baltic Sea is one of the world's most oxygen-depleted major bodies of water. The reason is excessive concentrations of phosphorus, an element essential for life—and an important ingredient in fertilizer. New research shows a way to possibly convert this problem into a resource that reduces Europe's dependency on phosphate mining while revitalizing the Baltic ecosystem.

A paper written by University of Florida Computer & Information Science & Engineering, or CISE, Professor Sumit Kumar Jha, Ph.D., contains so many science fiction terms, you'd be forgiven for thinking it's a Hollywood script: Nullspace steering. Red teaming. Jailbreaking the matrix. But Jha's work is decidedly focused on real life, most notably strengthening the security measures built into AI tools to ensure they are safe for all to use.

Many Canadians say they care about ethical products. They want coffee that supports farmers, chocolate made without child labor and everyday goods that are better for the environment.

People have long given up on the search for the Fountain of Youth, a mythical spring that could reverse aging. But for some scientists, the hunt has not ended—it's just moved to a different place. These modern-day Ponce de Leóns are investigating whether gut microbes hold the secret to aging well.

In the journal Antiquity, Dr. Shokouh Khosravi published preliminary findings of the largest known corpus of prehistoric seal impressions in the entire ancient world. The corpus, made up of over 7,000 seal impressions, more than 200 clay figurines, clay tokens, and two cylinder seals, dates back to 5,000 years ago and speaks to the fact that Tapeh Tyalineh was likely an important center involved in extensive commercial exchange, necessitating a large administrative system that likely left behind these seals.

Publicly funded research underpins much of daily life, from policy decisions to innovation and public debate. When research remains inaccessible, its value is diminished. Australia has made real progress on open access to research. In 2024, around 59% of papers authored by researchers in Australia were freely available online.

Reservoir computing is a promising machine learning-based approach for the analysis of data that changes over time, such as weather patterns, recorded speech or stock market trends. Classical reservoir computing techniques are known to perform best at the "edge of chaos," or in simpler terms, at a "sweet spot" in which the behavior of systems is neither entirely predictable (i.e., order) nor completely unpredictable (i.e., chaos).

A new study from the Advocate Aurora Research Institute published in Hospital Pediatrics provides guidance for families and physicians caring for infants and young children hospitalized with a febrile urinary tract infection (UTI), one of the most common infections in early childhood.

When we think of ice on Mars, we typically think of the poles, where we can see it visibly through probes and even ground-based telescopes. But the poles are hard to access, and even more so given the restrictions on exploration there due to potential biological contamination. Scientists have long hoped to find water closer to the equator, making it more accessible to human explorers. There are parts of the mid-latitudes of Mars that appear to be glaciers covered by thick layers of dust and rock.

Online chat service Discord has announced it will begin testing age verification for some users, joining a growing list of platforms trying to work out who is actually behind the screen.

The financial industry is entering a new era, with AI and new regulations on accessing data transforming how finance works. These changes are giving people more options to manage their money in new ways—taking us closer to totally cashless transactions.

Picture this: A group of girls are sitting at a table in the lunchroom when a boy walks by. One girl turns to another girl and laughingly says, "Oh, isn't that your boyfriend? You should go kiss him!"

Archaeologists have discovered a tomb more than a thousand years old in Panama containing human remains alongside gold and ceramic artifacts, the lead researcher told AFP on Friday.

Scientists at McGill University and the Rosalind and Morris Goodman Cancer Institute have developed a new way to deliver cancer immunotherapy that caused fewer side effects compared to standard treatment in a preclinical study. The work is published in the journal Proceedings of the National Academy of Sciences.

People with ulcerative colitis (UC), a chronic inflammatory bowel disease, are up to four times more likely to develop colorectal cancer than the general population. Low-grade dysplasia (LGD)—abnormal or precancerous lesions—can be an early warning sign, but only a fraction of UC-LGD cases progress to cancer. This makes it challenging for clinicians and patients to make informed care decisions, ranging from continued surveillance to preventative surgery.

The laser you see in the photo above may one day enhance images taken by the most powerful microscopes in biology. This advancement, detailed in a paper published in eLife from scientists at Columbia's Zuckerman Institute with the Maxson lab at Cornell University, could revolutionize research into the molecules that allow the brain to function properly and underlie diseases.

Magnetic resonance imaging (MRI) is one of medicine's most powerful diagnostic tools. But certain tissues deep inside the body—including brain regions and delicate structures of the eye and orbit that are of particular relevance for ophthalmology—are difficult to image clearly. The problem is not the scanner itself, but the hardware that sends and receives radio signals.

Smartphone cameras are becoming smaller, yet photos are becoming sharper. Korean researchers have elevated the limits of next-generation smartphone cameras by developing a new image sensor technology that can accurately represent colors regardless of the angle at which light enters. The team achieved this by utilizing a "metamaterial" that designs the movement of light through structures too small to be seen with the naked eye.

Scientists say they have drilled deeper than ever beneath the West Antarctic Ice Sheet, peering back millions of years to reveal signs it was once, at least in part, open ocean.

Humans tend to fear bed bugs, and rightly so. The bloodsuckers are tough to get rid of once they've entered a home. But new research has, for the first time, identified one thing the bugs seem to fear—water and wet surfaces.

Parenting can be hard and can feel especially overwhelming when children have strong emotions, such as anger, frustration or excitement, that they are not always able to regulate on their own.

Globally, nearly 7,000 coal mines, more than 2,400 coal-fired power plants and hundreds of coal rail networks, trucks and port terminals all make up the world's coal industry. When coal is phased out and green energy phased in, these coal assets can either be abandoned or turned into something that is useful for communities.

A study from an international team of experts in veterinary medicine, human medicine and genomics provides the first large-scale genetic map of feline cancer, revealing that cats may hold the key to understanding several human cancers.

For adults with asthma, having fans, air purifiers or other ventilation and exhaust systems—especially in kitchens and bathrooms—is one of the best ways to reduce the risk of flare-ups at home.

More than 150 giant tortoises have been reintroduced to Floreana Island in Ecuador's famed Galapagos archipelago where they disappeared more than a century ago, the environment ministry said Friday.

Deep in the folds of the intestine, in microscopic pockets called crypts, a quiet surveillance system is always at work. Stem cells lining the gut wall are not just rebuilding tissue—they are listening and signaling. When certain strains of Escherichia coli brush past, these cells can sense a telltale molecular signature: flagellin, the protein that powers a bacterium's whip-like tail. That signal sets off a chain reaction, summoning immune cells that repair damage and help restore the gut's protective barrier.

Eyes are said to be the mirror of the soul. Eyes and gaze direction guide attention, evoke emotions and activate the brain's social perception mechanisms. Researchers at Tampere University and the University of Bremen conducted a study examining how people perceive the minds of humanoid robots. Mind perception refers to the way humans detect and infer that other people, beings or even objects possess consciousness, emotions and cognitive states.

When you turn on a faucet, charge an electric vehicle or use products made with clean hydrogen, you may not realize that membranes—ultrathin films perforated with pores too small to see—make these modern processes possible. They purify water, recover valuable minerals and help power emerging clean-energy technologies. But despite their enormous importance, researchers still don't fully understand how water and ions move through these films at the molecular level.

Fred Hutch Cancer Center scientists reached a crucial milestone in blocking Epstein Barr virus (EBV), a pathogen estimated to infect 95% of the global population that is linked to multiple types of cancer, neurodegenerative diseases and other chronic health conditions. Using mice with human antibody genes, the research team developed new genetically human monoclonal antibodies that prevent two key antigens on the surface of the virus from binding to and entering human immune cells.

Just like each person has unique fingerprints, every CMOS chip has a distinctive "fingerprint" caused by tiny, random manufacturing variations. Engineers can leverage this unforgeable ID for authentication, to safeguard a device from attackers trying to steal private data.

Origami, the traditional Japanese art of paper folding, has received considerable attention in engineering. By applying paper-folding principles, researchers have created compact structures that are flexible, lightweight, and reconfigurable across aerospace, medicine, and robotics.

New kinds of aircraft taking to the skies could mean unfamiliar sounds overhead—and where you're hearing them might matter, according to new NASA research. NASA aeronautics has worked for years to enable new air transportation options for people and goods, and to find ways to make sure they can be safely and effectively integrated into U.S. communities. That's why the agency continues to study how people respond to aircraft noise.

When household batteries die, it's hard to know what to do with them. So they get shoved into a junk drawer or sheepishly thrown into the trash.

Researchers at the University of Maryland and Tilburg University in the Netherlands have produced an AI-driven innovation to reshape how marketers place digital ads. AdGazer, a predictive tool, evaluates both an advertisement and the media environment around it to forecast how much attention viewers will give. The result, they say, is smarter, more effective ad placement.

A University of Hawaiʻi at Mānoa student-led team has developed a new algorithm to help scientists determine direction in complex two-dimensional (2D) data, with potential applications ranging from particle physics to machine learning. The research was published in AIP Advances.

While the statement, "Humanoid robots are coming," might cause anxiety for some, for one Georgia Tech research team, working with humanlike robots couldn't be more exciting. The researchers have developed a new "thinking" technology for two-legged robots, increasing their balance and agility.

One night in 2010, Mohit Gupta decided to try something before leaving the lab. Then a Ph.D. student at Carnegie Mellon University, Gupta was in the final days of an internship at a manufacturing company in Boston. He'd spent months developing a system that used cameras and light sources to create 3D images of small objects. "I wanted to stress test it, just for fun," said Gupta, who would begin his postdoctoral research at Columbia Engineering a few months later.

Nvidia is on the cusp of investing $30 billion in OpenAI, scaling back a plan to pump $100 billion into the ChatGPT maker, the Financial Times reported Thursday.
