Sleep app tracks link between air pollution and a bad night’s sleep

Sleep app tracks link between air pollution and a bad night’s sleep Sarah Collins Tue, 09/15/2026 - 10:00 Researchers from the University of Cambridge, Tsinghua University and the sleep technology company Sleep Cycle analysed coughing sounds from 32 cities in 12 countries over 500 days, and found that higher daily air pollution levels were strongly linked to nighttime coughing levels, even where local pollution levels were below the World Health Organization’s recommended daily exposure limit. The researchers used cough sounds passively recorded by the mobile app via the phone’s microphone. Cough sounds were counted on individual devices and pooled by city to build an unprecedented dataset o...

Nearly 10,000 patients reveal what works best for knee arthritis pain relief

A major analysis of 139 clinical trials involving nearly 10,000 people suggests that some of the simplest treatments may work best for knee osteoarthritis. Knee braces ranked highest overall for reducing pain, stiffness, and mobility problems, while water-based therapy was especially effective for pain and regular exercise consistently improved both pain and physical function. More high-tech approaches, including ultrasound, generally performed worse.

A coral reef thought dead for 60 years is teeming with life

More than 60 years after surveys suggested a deep coral reef off Benin was probably dead, scientists have found it alive. Cameras revealed healthy-looking coral patches supporting multiple fish species more than 50 meters beneath the surface. The discovery suggests West Africa’s coastal waters may contain other overlooked reefs that have yet to be documented.

South American 'Pompeii': Volcanic eruption 22 million years ago preserved a snapshot of the Andes forming

A volcanic eruption 22 million years ago froze a snapshot of the Andes in their youth, revealing a slow-and-steady formation of this formidable mountain range. The eruption, which originated from the Lauca Caldera in what is now northern Chile, blanketed the landscape in a formation known as ignimbrite. This rock is left over after a pyroclastic flow ‪—‬ a mix of rock, volcanic gas and ash that sweeps over the landscape like a broiling tsunami. Pyroclastic flow is what buried the Roman town of Pompeii after the eruption of Mount Vesuvius in A.D. 79, preserving buildings and people where they fell. Now, a new study published Sept. 11 in the journal Science Advances extrapolates the landscape ...

Marine bacteria team up to break down one of the ocean's toughest carbon-storing molecules

Deep in the ocean, brown algae and diatoms produce a complex carbohydrate molecule called fucoidan, which helps form the algae's protective outer layer. The fucoidan molecule is very difficult for microbes to break down because its chemical structure may include dozens of different linkages and branching patterns that vary from one algae species to another. This resistance to decay is one reason why fucoidan matters; when microbes struggle to break it down, fucoidan can sink deep into the ocean, carrying carbon with it and potentially storing it for long periods. This could make fucoidan an important player in the ocean’s carbon cycle.For many years, scientists knew of individual bacteria th...

How did her sister become so sick so fast?

Joan Brugge. Niles Singer/Harvard Staff Photographer Health How did her sister become so sick so fast? Joan Brugge’s decadeslong professional fight against cancer began when she tried to make sense of a tragedy Anna Lamb Harvard Staff Writer September 14, 2026 6 min read A series focused on the personal side of Harvard research and teaching. Joan Brugge was on track to graduate from Northwestern University in a few years and launch into a career teaching math when a single phone call changed the direction of her life. “I was a sophomore and I got this call from my parents, sobbing, asking could I please come home because my sister was going to be operated on,” Brugge said. It turned out that...

We now have an incredibly detailed map to help predict which areas of LA are the most at risk from 'The Big One'

Scientists have a new view of the ground under Los Angeles, and it's a bit shaky. The 3D model of the Los Angeles basin shows that downtown LA is underpinned by up to 6.2 miles (10 kilometers) of sediment, which will likely amplify shaking from any earthquake that hits the region. That's not entirely new information, but the underground map is more precise than ever before, and it should help earthquake scientists better understand which areas of the city are most vulnerable. "With this improved model of the basin, we now know the shape of the edges of the basin in a lot more detail," Elizabeth Cochran, a U.S. Geological Survey seismologist who was not involved in the study, told Live Scienc...

But Gross, author of the new book “What Happened to College,” said in an interview that he was surprised by how much things had changed in recent decades. “I didn’t realize how far it had gone,” said Gross, who is currently conducting research at the Radcliffe Insti...

Cancer is rising in younger adults. Faster biological aging may help explain why

Cancer rates are rising in adults under 55, and new research suggests accelerated biological aging may be one piece of the puzzle. Scientists found that people from more recent generations tended to have bodies that appeared biologically older than those of earlier generations at the same chronological age. Greater biological age acceleration was linked to a higher risk of early onset cancers, with specific patterns seen for lung, gastrointestinal, uterine and colorectal cancers.

Wildfire strategy doesn't need a winner—with 3 camps fighting for dominance, the system can't keep up with the risk

One of the problems with how America deals with wildfires is the belief that there is one primary strategy that can end the nation's wildfire crisis. Whether that's detecting and putting out every fire fast, increasing logging and forest thinning, or allowing fires to burn under safe conditions, the default choice today is to pour more money and effort into the star approach of the moment.

Evolutionary home advantage: Field experiment reveals adaptation to be surprisingly local

A research team from the University of Bern has shown in a large-scale field experiment that populations of the same fish species can be much more fine-tuned to their local environments than previously thought. Habitats that appear nearly identical to us can therefore make a decisive difference in evolution. This hidden diversity is not only key to understanding how biodiversity arises, but also has important implications for its conservation.
