Phys.org / Scientists cut and rebuild molecules from the inside to create new chiral nanocarbons
Nanocarbons are molecular-scale carbon structures considered to be the building blocks for next-generation materials. Until now, scientists have built them by fusing small, flat carbon molecules together at their edges. Modifying ...
Phys.org / What is a p‑value? Expert explains the most misunderstood number in science
If you've ever tried to read a scientific paper, you've almost certainly run into a p-value. And if you found it confusing, you're in good company: Plenty of working scientists misunderstand it too.
Medical Xpress / Single patch merges multiple physiological signals for simpler health monitoring
Wearable health monitors have grown increasingly capable, but most are still limited by the fact that tracking different types of body signals requires separate sensors, each with its own circuitry and patch of skin. That ...
Phys.org / New thermodynamic framework explains pressure and edge currents in spinning active particles
Physicists from Heinrich Heine University Düsseldorf (HHU), the Technical University of Darmstadt, Sapienza University in Rome and the University of Camerino (both in Italy) have calculated the fundamental laws of thermodynamics ...
Phys.org / US residents near small rivers face disproportionately high future flood risks
An international team, including Kumamoto University and its partner institutions, has found severe flood risks and high climate-adaptation costs for U.S. small rivers.
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 ...
Dialog / AI-designed SARS-CoV-2 variants escape prevalent antibodies
While headlines warn that AI could unleash future biological threats, the technology also offers our best defense: a way to anticipate viral evolution and stress-test treatments. Rather than waiting for SARS-CoV-2 to mutate ...
Medical Xpress / Will dietary fiber help digestion? It might depend on your gut bacteria
Doctors recommend dietary fiber for healthy digestion, but to benefit from it, people not only need specific species of gut bacteria but also the right strains of those bacteria to process the starches, according to a new ...
Phys.org / Updating Darwin: Biologists are returning to an older theory to explain anomalies in evolution
Evolution is a fact of life. So much so that even the theory of evolution is evolving. Lately, a centuries-old discredited idea has been making a strong comeback. It helps us explain scientific observations that, according ...
Medical Xpress / How the heart's 'little brain' helps it function and protects it against stress
For years, scientists have known that the heart has its own network of nerves, the intrinsic cardiac nervous system (ICNS), sometimes called its "little brain." Exactly how it functions has remained something of a mystery, ...
Medical Xpress / Cyclospora boosts fears that deadlier foodborne outbreaks are ahead
The next foodborne illness outbreak could be much worse. That's the concern of food safety leaders across the U.S., who are raising alarms over federal cuts they say have made it harder to detect and stop the spread of foodborne ...
Phys.org / Humanoid classroom robots show potential as teaching assistants, not teacher replacements
A New York school district made global headlines this week for plans to trial a humanoid robot named "Sally" in high school classrooms.
