Medical Xpress / Poor sleep may nudge the brain toward dementia, researchers find
Staring at the ceiling while the clock blinks 3am doesn't only sap energy for the next day. A large, long-running U.S. study of older adults has now linked chronic insomnia to changes inside the brain that set the stage for ...
Medical Xpress / How to keep dementia from robbing your loved ones of their sense of personhood—tips for caregivers
Every three seconds, someone in the world develops dementia. There are over 6 million people living with dementia in the U.S. and 57 million globally.
Medical Xpress / Detection is not prevention: Will drug testing drivers really make NZ roads safer?

Medical Xpress / Q&A: Odds of surviving cancer drop drastically when credit score dips
While past studies have explored how cancer patients' financial health influenced their risk of mortality, new research digs in deeper by zeroing in on objective data: credit scores.
Phys.org / Our solar system is moving faster than expected
How fast and in which direction is our solar system moving through the universe? This seemingly simple question is one of the key tests of our cosmological understanding. A research team led by astrophysicist Lukas Böhme ...
Phys.org / String theory: Scientists are trying new ways to verify the idea that could unite all of physics
In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called "Is the end in sight for theoretical physics?"
Phys.org / If the supernova standard candle is wrong, it could solve the Hubble tension
Last time I wrote about new data that overturns the standard cosmological model. Before anyone starts dusting off their fringe cosmological models, we should note what this new study doesn't overturn. It doesn't say the Big ...
Phys.org / Global companies are still committing to protect the climate, and they're investing big money in clean tech
The Trump administration has given corporations plenty of convenient excuses to retreat from their climate commitments, with its moves to withdraw from the Paris Agreement, roll back emissions regulations, and scale back ...
Phys.org / Raman quantum memory demonstrates near-unity performance
Over the past decades, quantum physicists and engineers have developed numerous technologies that harness the principles of quantum mechanics to push the boundaries of classical information science. Among these advances, ...
Phys.org / Fight over fossil fuels drawdown looms at UN climate summit
Two years after nations agreed to transition away from fossil fuels, dozens are pushing to go even further at the COP30 climate summit, setting up a showdown with oil powers.

Scientists have discovered a fern from South China that naturally forms tiny crystals containing rare earth elements (REEs). This breakthrough opens the door to a promising new way of "green mining" of these minerals called ...
Phys.org / Offsetting blue carbon benefits: Mangrove tree stems identified as previously underestimated methane source
Mangrove ecosystems rank among the most efficient "blue carbon" systems on Earth, capable of absorbing and storing vast quantities of atmospheric carbon dioxide (CO2). However, mangroves also release methane (CH4), a potent ...
