An international study finds that older adults who have strong beliefs about how other seniors should behave also report having more memory problems themselves. The study suggests a relationship between "ageist attitudes" and memory.
Roughly 2.5–2 billion years ago, Earth's surface experienced the biggest chemical change in its history when oxygen became abundant in the atmosphere, eventually leading to the evolution of complex life forms such as plants and animals that emerged half a billion years ago.
Verheij syndrome is a rare genetic disorder caused by the impairment of splicing, a critical process in RNA processing. Using the model organism Caenorhabditis elegans, researchers at the Max Planck Institute for Biology of Aging have demonstrated that this disruption affects

A favorite toy or treat can become dangerous in an instant if it gets lodged in your pet's airway. Because choking is a terrifying emergency for pets and their owners, Dr. Christine Rutter, a clinical associate professor at the Texas A&M College of Veterinary Medicine and
Biofilms—bacterial communities encased in a sticky, polymer-rich matrix—can be difficult to treat because that matrix slows antibiotics and drug-carrying particles. With help from salt, though, Yale researchers have found a way to steer these particles into some biofilms and
This year's cuttlefish season has been unlike any other. Every winter, more than 100,000 giant Australian cuttlefish can usually be found mating along the rocky coastline of Point Lowly, northeast of Whyalla, South Australia. They put on shape-shifting, colorful displays in
Dogs are known to recognize and respond to human facial expressions, but a new study shows how deeply they understand our mood
Scientists—and dog lovers—have long known that dogs are remarkably good at interpreting our laughs, frowns and tears. But the biology behind this ability has remained largely unexplored until now. In a study published in the journal iScience on Aug. 7, researchers peered inside
As artificial intelligence rapidly reshapes education and the workforce, a majority of parents and educators believe it's essential for students to develop data literacy skills, according to a new survey released today by Data Science 4 Everyone and Mathematica.
A new brain-imaging study suggests that dogs may be able to distinguish between certain negative human emotions just by looking at people’s faces.
An experimental GLP-1 pill helped people with obesity or overweight lose as much as 12.1% of their body weight in just 36 weeks. Unlike injectable drugs such as Wegovy and Ozempic, aleniglipron is a small molecule that can be taken once daily with or without food and could
As of June 2026, El Niño has officially arrived. This naturally recurring phenomenon is characterized by warmer-than-normal water temperatures in parts of the equatorial Pacific, along with changes to atmospheric and oceanic circulation patterns. Its regional effects range from

This summer has been marked by multiple outbreaks of foodborne illness, with thousands of infections and two deaths arising from cyclosporiasis and hundreds of cases of Salmonella
A little over a week ago, artificial intelligence company OpenAI announced 10 advances in mathematics and computer science made with its as-yet-unreleased model Astra. The discoveries cover a wide range of mathematical fields, including geometry, cryptography and coding theory.
Engineers have developed a strain of a common bacterial species that can feed exclusively on the three major sugars present in corn stalks. While the new multiple-sugar-consuming strain of the bacterium Pseudomonas putida is interesting in its own right, a new paper published
A late-summer monsoon in 2026 brought the Great Barrier Reef a reprieve from unfolding coral bleaching, aiding its initial recovery from recent climate-induced disturbances, according to the Australian Institute of Marine Science's (AIMS) annual survey report on the ecosystem.
Hundreds of Venus-like planets could soon help determine why some worlds become sweltering greenhouse hellscapes while others remain capable of supporting life. But before answering that question, scientists first need to know how fast those planets are spinning.

We're being promised a revolution. Artificial intelligence is said to make work both more productive and more enjoyable by freeing us from tedious tasks and allowing us to devote more time to what really matters. This is the narrative of "augmented work."
Mirrors normally reveal what is placed in front of them, even when their curvature distorts a reflection. Researchers at the University of California, Los Angeles (UCLA) have introduced a different optical concept: a "lying mirror" that hides information carried by an input
Children with attention-deficit/hyperactivity disorder (ADHD) often struggle with executive functions—tasks involving managing their time, completing their homework, turning in assignments and planning for upcoming projects. These limitations, says clinical psychologist Jenelle
Very high levels of the inherited cholesterol-related particle Lp(a) were linked to a greater risk of major cardiovascular events, particularly stroke and cardiovascular death, in a study of more than 20,000 people. Since elevated Lp(a) often flies completely under the radar, a
Meat eaters view plant-based meat as riskier and offering less value than conventional meat, regardless of how it is marketed, according to new Adelaide University research.
July also saw its second-highest air temperatures on record this year
School device use links with lower test scores and distractions abound. But reversing the entrenched pandemic pivot to screens will be hard.
New research from The University of Manchester has found that urban canals can cool their immediate surroundings by more than 2°C during heat waves.
Silver nanocatalysts have been found to switch where they perform their most important reactions depending on whether a solid oxide cell is making electricity or hydrogen. The discovery could enable smarter catalyst designs that boost clean power generation while making green
At the top and bottom of the planet, the seasons arrive on a schedule all their own. Satellite data from a mission measuring infrared energy reveal just how differently—and how dramatically—surface temperatures swing across two full years at the poles.
Russia's invasion of Ukraine in February 2022 had an almost immediate impact on global energy markets and the movement of food around the world. During the first year of the conflict, international crude oil and natural gas prices rose sharply. Disruptions to exports of wheat,

A 240-million-year-old reptile discovered in Brazil is revealing what evolution looked like just before the rise of dinosaurs and crocodiles. The small predator had unusually positioned legs that may have allowed it to move more efficiently than many earlier reptiles. Its close
The rise of the potato in the Andes appears to have left a lasting mark on human DNA. Indigenous Peruvians carry exceptionally high numbers of a starch-digestion gene, likely because people with more copies gained an evolutionary advantage once potatoes became a staple food.
Decades of selective breeding and intensive agricultural practices have reshaped cattle genetics—often at the expense of valuable diversity preserved in traditional herds—according to new research from Aberystwyth University.
An international research team partly led by the University of Ottawa reports that Petermann Glacier in northwest Greenland calved a 76.4 km² (29.5 square miles) ice island on Aug. 4, 2026, marking the glacier's largest loss of floating ice since 2012 and the largest Arctic
