Phys.org / We can predict space weather—what if we could also stop it?
The weather on Earth can get pretty messy sometimes. But in space, it can be wild, and the effects can be far-reaching. Solar flares, giant explosions on the sun, can send out streams of energy that block radio communications ...
Phys.org / Dynamic nanogates let longer molecules pass faster through flexible pores
A research team led by Professor Shuichi Hiraoka at the University of Tokyo and Professor Masanori Tachikawa at Yokohama City University has quantitatively analyzed how molecules pass through dynamic nanoscale pores using ...
Phys.org / Kamo'oalewa asteroid's lunar origin challenged ahead of Tianwen-2 arrival
China's Tianwen-2 sample-return mission is well on its way to its target, an asteroid called Kamo'oalewa. The spacecraft left Earth in May 2025 and should return in late 2027 with samples of a space rock that scientists had ...
Phys.org / A new capability to detect chemical weapons involves two existing methods
In the aftermath of suspected chemical attacks, investigators from the Organization for the Prohibition of Chemical Weapons (OPCW) step in to collect chemical, environmental, and biomedical samples. Thorough forensic laboratory ...
Dialog / Research could pave the way for more resilient winter cereals in warmer climates
The arrival of winter marks not only a change in weather, temperature, and day length, but also a change in our activity and behavior. The social outdoor events and trips to the beach over summer soon become a distant memory, ...
Phys.org / Arctic river deltas face rising climate pressure while holding vast frozen carbon reserves
Many rivers flow into the Arctic Ocean north of the Arctic Circle—including the Lena in Siberia and the Mackenzie River in Canada. The deltas of these large and small rivers store large amounts of carbon, which is bound there ...
Phys.org / How a Richard Feynman formula could explain your dining habits in a new city
One of the dilemmas facing anyone in a new and unfamiliar city is where to dine out. You might consult guides, speak to locals, check reviews, and ultimately, try your luck. But if you're there for a while, at some point ...
Medical Xpress / Are you sleep deprived? Your spit may hold answer
Sleep loss dulls alertness and coordination, and it can produce effects similar to severe intoxication, making actions like driving incredibly risky. But there's no clinical test for determining when someone is dangerously ...
Phys.org / Overarming America: Game theory explores how fear and social pressure drive gun purchases
A Dartmouth College study is the first to map the interplay of personal choice and social networks that has led to the United States being one of the world's most heavily armed countries, with 120 firearms for every 100 people. ...
Phys.org / Thundering footsteps warn caterpillars of lethal ladybeetle attacks
Diminutive warty birch caterpillars (Falcaria bilineata), less than 1.5mm long, ardently defend their leaf tip homes from invading caterpillars by scraping and pounding the leaf to warn off potential invaders. But how might ...
Phys.org / Britain's oldest cave art may have been rediscovered in Bacon Hole cave
The oldest cave art in Britain may have been discovered, or more likely rediscovered, in a cave on the Gower Peninsula in South Wales, possibly dating back around 17,000 years.
Medical Xpress / Major surgery may accelerate memory loss in 1 in 7 older adults
Going through surgery can take a significant toll on a patient's physical health and capabilities, especially if they are elderly. A recent study found that the effects extend far beyond mobility and pain management, as the ...
