Phys.org / Falling space debris poses an escalating risk as spacecraft get stronger and more heat resistant
When it comes to space debris, what goes up is coming down more often—and not safely.
Medical Xpress / Why teen health visits still lack privacy, even when most parents support it
While most parents say it's important for health care providers to speak privately with teens during checkups, far fewer are putting that belief into practice, according to a new national poll.
Phys.org / Saturday Citations: Prehistoric dentistry; sleep and aging; our photogenic sun
This week in science news: Are you a mosquito magnet? Here's why. Researchers using topological mathematics have uncovered a hidden rule in abstract art that corresponds to people's perceptions. And scientists developed a ...
Science X / Your brain has a shortcut for hard problems, and it starts by ignoring most of them
What's the best way to learn a puzzle or solve a problem? Consider a task where you must predict the weather from mysterious symbols. Should you try to interpret all the clues at once, or master them one by one? A new study ...
Medical Xpress / Weight-loss drugs tied to lower death, recurrence risk after breast cancer
New research published in JAMA Network Open suggests that there is a positive association between GLP-1 agonists—drugs commonly used to treat obesity and diabetes—and better outcomes among breast cancer patients.
Medical Xpress / How the brain switches between older and newer memories
As humans and other animals experience new things, their brains continuously update their memory of past events. These updates allow them to adapt to changing environments, all while preserving older memories that could still ...
Phys.org / Why emus can't fly: A 'time switch' in bird embryos holds the answer
Why can eagles soar through the skies while emus are bound to the earth? One secret lies in a skeletal structure called the keel, a blade-like ridge on the breastbone that anchors the flight muscles needed for powered flight. ...
Phys.org / Strange 500-million-year-old marine fossils reveal a feeding strategy that still shapes oceans today
More than 500 million years ago, during what is known as the Cambrian period, the seas and oceans on Earth were filled with a myriad of marine animals, many of which have now become extinct. This evolutionary burst in new ...
Phys.org / Common cancer protein may be therapeutic target, study finds
A protein doctors routinely use to measure how aggressively tumors are growing may also help prevent the chromosome errors that drive cancer, new research by academics at Brunel University of London suggests.
Tech Xplore / 'Touch dreaming' helps humanoid robots handle five tricky tasks with 90.9% higher success
Humanoid robots, robotic systems with a body structure that resembles that of humans, could soon assist humans with various tasks in household environments, manufacturing sites, hospitals and other settings. While some humanoid ...
Phys.org / Atomic bands in two transition metal dichalcogenides hint at long-theorized quantum state
Insulators are materials in which electrons cannot move freely. Past theoretical studies predicted the existence of an unusual insulating state dubbed obstructed atomic insulator (OAI), in which electrons are localized inside ...
Phys.org / Hidden small RNA in cholera bacterium helps determine whether it can infect humans
Scientists from St. Jude Children's Research Hospital have uncovered what gives Vibrio cholerae, the bacterium that causes cholera, the ability to colonize the human gut. The researchers found that a small RNA embedded within ...
