Researchers analyzing data from more than 1.9 million people found that ADHD is associated with substantially higher rates of digestive problems. People with ADHD had nearly double the odds of constipation, 58% higher odds of irritable bowel syndrome, and more than four times the odds of encopresis.
Industrialized countries send millions of metric tonnes of used clothing, electronic equipment and other products to the Global South, along with the environmental and health costs tied to producing, consuming and disposing of those goods.
Saccharina latissima, or sugar kelp, is one of the dominant species in Maine's kelp forests, providing food, habitat and clean water to support a rich marine ecosystem. It is also the bedrock of the state's burgeoning kelp aquaculture industry, which relies on the annual harvest of reproductive tissue from the wild.
The brain undergoes dramatic changes during puberty and pregnancy, but during menopause, the organ's structure remains remarkably stable, a new study suggests. The research, published Sept. 8 in the journal Nature Communications, examined the brain's gray matter, which mostly includes the wrinkled outer surface of the organ, called the cerebral cortex. Past studies have found that the volume of gray matter shrinks markedly during puberty and pregnancy, likely reflecting a fine-tuning of neural circuits during those periods.There's also a gradual decline in gray matter during adulthood that's seen as a normal part of aging, said study co-author Sophie van't Hof, a doctoral student in psychiat...
The CL Companion is Swarovski's dedicated compact binocular, originally introduced 15 years ago, but has now been redesigned in 2026 to appeal to a wider, younger audience. RSPB research found an increase of around 1,000% in birdwatching among Gen Z in the UK since 2018, with a similar boom now happening in the US. The CL Companion sits between the pocket-size CL Pocket and full-size EL and NL ranges, making it the perfect mid-range model that combines portability with excellent optical prowess. The Companion is a grab-and-go, "take it anywhere and everywhere" binocular that is perfect for many different activities, whether that's spotting birds, scoping out your hiking trail or sweeping acr...
Two studies find signs of strange black hole binary systems
NASA’s formidable gamma-ray burst hunter is doomed to soon reenter Earth’s atmosphere, leaving a glaring gap in our view of the high-energy sky
For more than a century, pharmaceutical companies have relied on flat structures called aromatic rings, which can help drugs bind to target sites in the body. They include benzene rings and other flat, nitrogen-containing rings. But there are limits to their usefulness.
The largest hoard of Viking Age silver ever found in Finland — which contains almost 10 pounds (4.5 kilograms) of coins and jewelry — has been unearthed by a metal detectorist about 95 miles (150 kilometers) north of Helsinki. The hoard had been divided into two deposits and buried in birch-bark containers. Although the coins and jewelry likely date to between A.D. 1000 and 1050, it's unknown exactly when they were buried, Esko Tikkala, an archaeologist at the Lahti Historical Museum who excavated the hoard, told Live Science in an email.The hoard has not yet been fully cleaned, separated and counted yet, but there are thousands of pieces, Tikkala said. "There are quite a lot of coins in thi...
What do we lose when machines become our closest confidants?
Many people are familiar with melatonin, a hormone that helps ready the body for sleep. But there's another, lesser-known chemical in the brain, called orexin, that tips the scale in the other direction: waking the body up. In 1999, two scientists independently uncovered the function of orexin and published papers about it. Dr. Masashi Yanagisawa, a molecular biologist and physician now at the University of Tsukuba in Japan, came across orexin while studying the interaction of receptors and chemicals in the brain. Dr. Emmanuel Mignot, now the director of the Stanford Center for Narcolepsy, homed in on orexin while studying narcoleptic dogs. (His Chihuahua, named Watson, has narcolepsy, and h...
A quarter of a century after the Twin Towers fell, those who lived through the attacks are still seeking care for myriad illnesses, including cancers, post-traumatic stress disorder, and more
Indonesian authorities are working to repatriate five baby orangutans allegedly trafficked to India, where they were found motherless in a forest, Jakarta's forestry ministry told AFP on Friday.
Research shows that short practices of mindfulness are as good as, if not better than, long ones. Columnist David Robson takes a look at how we can incorporate these microhabits into our daily lives
A revolution in forecasting natural disasters is underway, say researchers in Switzerland who are training AI models using vast troves of NASA climate data to produce potentially lifesaving data at lightning speed.
Unconventional quantum theories may imply that time itself has a tiny fundamental uncertainty, placing an ultimate limit on how precisely any clock could measure it. The effect is far beyond current detection, but it could reveal a hidden connection between quantum mechanics, gravity, and spacetime.
A remarkably detailed study of Maria Branyas, who lived past 117, reveals that extreme longevity may involve both intense aging and powerful biological protection at the same time. Researchers found signs of advanced aging, but also low inflammation, beneficial gut bacteria, protective genetic features, and a biological age younger than her chronological age. Because she avoided major disease, the study offered a rare look at aging itself rather than the illnesses that often accompany it.
The southern region of the Democratic Republic of Congo (DRC) is known as the Copperbelt because of its rich deposits of copper and other minerals.
Researchers have shown for the first time that human heart muscle cells can regrow after a heart attack. The finding overturns the idea that damaged areas of the heart are completely incapable of regeneration. Scientists now hope to identify ways to dramatically boost this natural repair process, potentially opening a new path toward treatments for heart failure.
London has one of the lowest violent crime rates of any region in England and Wales, tops a global ranking of the best cities, and pays more in taxes than it receives back in public spending—but the public overestimates how likely Londoners are to become victims of crime, underestimates the capital's international standing, and has little idea it is the key contributor to public finances, according to a new study from the Policy Institute at King's College London.
Eating only between noon and 8 p.m. improved blood sugar control in a small study of adults with Type 1 diabetes and obesity, while avoiding an increase in serious complications. The promising findings offer the first evidence that time restricted eating could become another tool for managing the condition.
Give, eat, cook and serve are everyday English words. On TikTok, they're doing something different.
Scientists have discovered that the Moon-forming collision may have depended heavily on how hot and physically strong early Earth and Theia were. New simulations found that some impacts create the familiar disk of debris that later becomes the Moon, while others can produce an intact Moon in only about five hours. The results challenge the long-standing assumption that the enormous collision could be modeled as if both worlds behaved mostly like fluids.
Money market funds (MMFs) that grow rapidly when equity markets are soaring pose a systemic risk to global financial systems, new academic research reveals.
