Welding plastic is a critically important part of everyday engineering—especially for preventing leaks in underground water and gas pipes. For decades, engineers have understood that a properly welded joint in polyethylene pipe can be just as strong as the pipe itself, if not
In 1899, scientists began tracking avian migration by placing a small ring with an identifier around birds' ankles. Researchers then had to recapture the birds elsewhere, leaving the journey between those points a mystery. Today, GPS tags allow researchers to see every stage of
Single-use paper cups used for takeout coffee and other beverages release millions of microplastic particles when exposed to hot liquid, University of Queensland researchers have found.
Children in the postmedieval Dutch workforce worked so hard that their spines became worn and deformed, with some children affected before they even had a chance to lose their baby teeth, a new study published in the International Journal of Paleopathology finds.
A ketogenic diet outperformed Mediterranean and low-fat diets in several measures of metabolic health during a clinical trial involving people with obesity, prediabetes, and fatty liver disease. All three groups lost about 10% of their body weight, but keto reduced liver fat by
The Roman Space Telescope will spend more than a quarter of its time staring at the Milky Way’s bulge, a star-packed central region of our galaxy that may swarm with small, rocky exoplanets
Dogs and humans may have more in common when it comes to aging than scientists realized. Researchers with the Dog Aging Project found that patterns of small molecules in dogs’ blood were linked to longer or shorter lifespans in remarkably similar ways to those seen in people.
Researchers have discovered a way to turn notoriously difficult-to-recycle PVC plastic into a key ingredient used in high-performance lubricants such as engine oil. The technique could give mountains of plastic waste a valuable second life while making lubricant production more
There have been multiple high-profile alleged incidents of sexual violence against women and girls in news headlines this month. Some involve teenage boys.
Czech researchers at Charles University in Prague, led by Pavla Eliášová, have developed an advanced photocathode that helps convert the greenhouse gas carbon dioxide into pure ethanol using sunlight. The new technology solves a long-standing problem of material degradation in
Part of the challenge of finding a biomarker for mental illness is the environment’s significant influence The post I’m Part of the Team Writing the Next Bible of Psychiatry—For the First Time, the DSM Will Use Biology to Understand Mental Disorders appeared first on Nautilus .
A major new analysis challenges recent claims that the universe's expansion is slowing, finding that the evidence for cosmic acceleration remains strong. The findings preserve the leading role of dark energy, while leaving scientists with the enduring mystery of what this
People with chronic insomnia who used melatonin long term had a roughly 90% higher risk of developing heart failure over five years, according to a large preliminary study. The findings do not prove melatonin causes heart problems, but they raise new questions about the safety
Researchers have discovered that Western Australia’s iron-rich rocks can naturally generate hydrogen and that the process may be boosted to produce much larger amounts. If it can be scaled up, the vast formations beneath the Pilbara could become a major new source of
Seasonal changes have more effects on your biology and behavior than you might realize
Frequent micro-awakenings during sleep were linked to higher genetic risk for Alzheimer’s in healthy middle-aged adults who had no symptoms. The discovery raises the possibility that subtle changes during sleep could offer an early warning signal years before memory problems
Scientists have identified a protein that acts like a brake on the nervous system’s ability to repair damaged connections. Blocking AHR helped injured nerve fibers regrow and improved movement and sensation in mice with nerve or spinal cord injuries. The discovery could
As many cities developed, streams that once flowed on the surface were buried underground to make way for growing infrastructure. However, as heavier rainfall, extreme weather and aging infrastructure place growing pressure on cities, these buried streams could become part of
When an insecticide application fails to control bluegreen aphid, application conditions may not be the only cause. Research has identified resistant populations across southern Australia, confirming that repeated reliance on broad-spectrum insecticides is no longer sustainable.
Since the release of ChatGPT in 2022, artificial intelligence (AI) has dominated the cultural landscape. Uptake across various sectors, including law enforcement, quickly followed, usually with minimal foresight and little to no guardrails, like effective policies or laws, to
Tina Nyfors, who recently defended her doctoral thesis at the University of Helsinki, studied sufficiency, a way of living and a principle for organizing society to stay within environmental limits while ensuring that people have enough. Nyfors directs attention to people whose
It started with a simple message: "This is the year to do something small for something huge." Now, 17 years later, the Whitsundays region has some of the best protection in the world for migrating humpback whales.
Temperatures have warmed dramatically across the equatorial Pacific Ocean in 2026, signaling the onset of a strong and potentially historic El Niño. These events can affect weather around the world, and the intensity of recent El Niño events is raising alarm that, as global

Subterranean clover's ability to bury its seed supports pasture persistence but makes commercial seed harvesting difficult. The industry relies on aging Horwood-Bagshaw (HB) suction harvesters, which collect seed from fully dry crops after repeated tillage and raking.

In 2020, Mexico joined 150 nations committing to protect 30% of its territory by 2030 as part of the global 30x30 initiative. More than halfway through the decade, there is ongoing debate about how to effectively expand protected areas to meet that ambitious goal.
Graphene is an exceptionally useful material for creating batteries, catalysts and electronic devices. Yet producing graphene typically requires temperatures as high as 900°C (1,652°F), limiting energy efficiency and making structural control difficult. To make graphene
Restaurants that go beyond simply allowing dogs on patios by offering dedicated menu items for them can significantly boost customer traffic, spending and word-of-mouth, according to new research from Toronto Metropolitan University.
Seven Rasmussen, an astrobiologist and author of the new book Cloudy with a Chance of Starships , gives readers a tour of the astonishing science behind modern searches for alien life
Fast fashion is built on cheap, short-lived garments, especially cotton and polyester T-shirts. To sustain its profits, the industry relies on high production frequency, short product lifespan and a globalized supply chain. All these elements contribute to making the industry a
Some of nature's most important chemical reactions rely on the coupled movement of negatively and positively charged particles. These processes play central roles in photosynthesis, catalysis and biological energy conversion yet remain difficult to observe.
Does the devastating flooding unleashed by the collapse of a section of a glacier in the Nepali Himalayas signal a new kind of risk in a world warmed by climate change? Here's what scientists told AFP.
