Medical Xpress / Silver diamine fluoride treatment could halt cavities without shots, drilling or sedation
Every year, untreated tooth decay sends thousands of young U.S. children to emergency departments for dental problems doctors can't treat. Many eventually undergo surgery under general anesthesia, while others endure pain ...
Phys.org / Kids who own cellphones have poorer reading comprehension scores than those who don't, researchers find
School cellphone bans might seem like a good way to improve learning for elementary school children, but new research published in Behavioral Sciences shows that simply owning a cellphone correlates with worse reading comprehension. ...
Tech Xplore / Reconfigurable AI device preserves long-term memory while acoustic waves reset short-term signals
A research team led by professor Il Jeon of the Department of Nano Engineering and the Sungkyunkwan Advanced Institute of Nanotechnology (SAINT) at Sungkyunkwan University, including Dr. Sihyeok Kim and Dr. Jang Woo Lee, ...
Phys.org / How invasive rats rewire coral reef food webs to create winners and losers
Invasive rats on tropical islands are creating winners and losers among the tiny underwater animals near the bottom of the food chain that inhabit surrounding coral reefs. Scientists say the changes to these marine ecosystems ...
Phys.org / Dynamic 'breathing' in nanopore structures can maximize efficiency of molecule separation and diffusion
Nanoporous material-based separation technology is vital in many applications because it can precisely distinguish between and separate nearly identical chemical or biochemical molecules.
Science X / Different flint, same toolmaking strategy: How Neanderthals adjusted their effort to get the same razor-sharp results
The Neanderthal toolkits found in two Ice Age caves near Le Moustier, in southwestern France, tell a surprising story. Even though the types of rock were very different—large, high-quality flint nodules at Le Moustier and ...
Medical Xpress / Blood vessel building revealed: Cells push, anchor and pull to connect flowing channels
How do blood vessels form to reliably supply the body with oxygen and nutrients? A research team at the University of Basel has uncovered a key mechanism by which cells join to build new blood vessels.
Phys.org / A lipid switch that blocks anthrax from entering cells
Every cell carefully builds and positions thousands of proteins that allow it to sense and respond to its surroundings. Even small changes to these proteins often determine whether they work properly or are destroyed before ...
Medical Xpress / Dreams drain energy: The REM sleep paradox
The brain demands a lot of energy compared with other organs. However, it can also make do when energy supplies are scarce, flexibly processing information using what is available. How the brain resourcefully allocates this ...
Phys.org / Helical nanoparticles trigger cancer alarms and deliver gene therapy
Cancer cells survive by hiding from the immune system's surveillance. A KAIST research team has developed a new anticancer platform that makes cancer cells send out their own danger signals—prompting immune cells to attack—while ...
Phys.org / More green space alone won't beat urban heat
New research from Victoria University (VU) reveals that reducing the impact of extreme heat in urban areas requires more than simply adding green spaces—it requires a different approach to urban planning.
Phys.org / Self-cleaning nanoscale sensor could transform personalized medicine
Imagine a smart bandage that could continuously monitor an infected wound, alerting doctors when bacteria spread or when treatment begins to work. That vision is one step closer to reality with new research from Virginia ...
