Phys.org / Each degree of warming could add a month of intolerable heat for 1 billion people
The threat that rising temperatures fueled by climate change pose to the health of older people has been dramatically underestimated, according to a U.S. modeling study published Tuesday.
Medical Xpress / What is a thought made of? Scientists look beyond neurons—and raise new questions about AI
A familiar song can bring back a memory from decades ago. A particular smell can recall a person or place. And a frightening memory can trigger a simultaneous emotional and physical response almost instantly. Computers, too, ...
Phys.org / Fifteen years of data link plastic pollution to seabird population losses
Every year, about 50 million metric tons of plastic is dumped into the environment. This waste entangles, chokes and poisons wildlife worldwide, including sable shearwaters living on the remote Australian island of Lord Howe. ...
Phys.org / Perovskite-based sensor detects ammonia leaks at concentrations as low as 1 ppm
A team led by principal researcher Myungkwan Song of the Energy & Environment Materials Research Division at the Korea Institute of Materials Science (KIMS) has developed an ultrasensitive ammonia gas sensor using an environmentally ...
Phys.org / Dice design solves board gaming's most surprisingly complex problem—who goes first?
It took nearly 15 years, researchers around the world and enough computing power to search through a universe of possibilities to answer one question: Who goes first?
Phys.org / Structural snapshots reveal key steps in switching on DNA replication
Every time a cell divides, it must accurately copy its entire genetic instruction manual. Before this process can begin, cells load their DNA-copying motor—a complex of six subunits known as the MCM2-7 helicase—onto DNA. ...
Phys.org / Does 'AI‑watermarking' mean the party is over for cheating students?
Concerns about students cheating with AI are rife in schools and universities.
Phys.org / How only a few tree species drive Amazon forest recovery
When a destroyed section of the Amazon rainforest begins to recover, nature deploys only a few tree species that can withstand poor soil conditions and blazing sun and grow rapidly, a Brazilian study has shown.
Phys.org / Building real-time control for engineered biological systems
Scientists can engineer living cells to perform useful tasks, from producing medicines and sustainable chemicals to detecting disease. Unlike traditional engineered systems, living cells are constantly changing as they grow, ...
Phys.org / Deep-learning approach rapidly predicts where metals bind within proteins
In the living world, roughly a third of all proteins we know rely on metals to function. Zinc helps enzymes break down molecules, iron helps carry oxygen in the blood, calcium helps relay signals in cells and potassium flows ...
Phys.org / An African bat overlooked for two centuries is confirmed in Europe
An African bat whose presence in Sicily had remained an unresolved zoological mystery for almost two centuries has now been documented on Pantelleria Island. A study published in Global Ecology and Conservation reports the ...
Medical Xpress / Signs of Alzheimer's disease are detectable far earlier than previously thought
A new study suggests that Alzheimer's disease may be detected by brain imaging more than seven years earlier than previously assumed. Researchers from the Department of Psychology at the University of Oslo led the study, ...
