Phys.org / Salty drinking water could be increasing your blood pressure. People living in coastal areas are most at risk
When people consider what causes high blood pressure, they often think of lifestyle factors, such as eating salty foods, lack of exercise or smoking. However, an unexpected source of salt might also be raising blood pressure ...
Phys.org / Bonobos' peaceful reputation cracks after a rival group attack leaves an infant dead
Bonobos are often described as gentle apes, generally calm primates that are seen as peacemakers in the animal kingdom. But this reputation may be coming under attack as a new study published in Scientific Reports reveals ...
Phys.org / 'Ghost tunnels' guide sound waves in one direction while staying invisible to others
Acoustic metamaterials are a fast-evolving family of materials which manipulate sound waves in ever more advanced ways. Now, a team led by Changqing Xu at Nanjing Normal University in China has engineered an acoustic metamaterial, ...
Medical Xpress / Overlooked ribosomal DNA may help explain human size differences
Ribosomal RNA (rRNA), made from many copies of ribosomal DNA (rDNA), is the core component that powers ribosomes—protein-building machines in our body. It helps build proteins by linking amino acids together, and can also ...
Phys.org / JWST spots methane on a giant exoplanet, but its star may be distorting the signal
Using the James Webb Space Telescope (JWST), astronomers from Johns Hopkins University (JHU) and elsewhere have observed a giant exoplanet known as HATS-75 b. Results of the new observations, published April 8 on the arXiv ...
Phys.org / Copper blasted into a million-degree plasma strips away 22 electrons in a flash before atoms recover
When laser flashes hit matter, electrons are knocked off their orbits around the atomic nuclei. This can generate extremely hot plasmas composed of charged particles—ions and electrons. Researchers at HZDR have now observed ...
Phys.org / Sperm whale clicks follow similar rules to human speech
Sperm whales produce powerful clicks to communicate. To our ears, they sound nothing more than a series of repetitive, mechanical taps. But we could be a step closer to understanding some of their complex communication, as ...
Medical Xpress / Chloride ions do more than help neurons fire—they may also help control how genes are expressed
Chloride ions, best known for helping cells maintain fluid balance and electrical stability, may also play a more direct role in regulating brain development than previously thought. In a new study, published in the journal ...
Phys.org / Cracking a 16-year proton mystery as ultra-precise hydrogen measurements confirm a smaller-than-expected core
The simplicity of a hydrogen atom makes it an ideal model for studying atomic structure and interactions. Yet, despite the fact that its simplest form consists of only one proton and one electron, physicists have had a hard ...
Phys.org / A newly recognized pollutant is widely present in the atmosphere
A new study shows that a specific type of silicone, the so-called methylsiloxanes, is widely present in the atmosphere across diverse environments. Also, concentrations appear to be much higher than expected. According to ...
Phys.org / Volunteers discover rare space weather events using their ears
Our planet rests inside a magnetic cocoon filled with plasma—but it's not always peaceful and quiet. Activity from the sun can send waves through this space, and some of those disturbances can even reach Earth, affecting ...
Tech Xplore / Transparent cooling film cuts car cabin temperature by 6.1°C without electricity
A transparent radiative cooling film technology that dissipates heat directly to the outside without consuming electricity has been developed to reduce vehicle overheating during summer. The technology was validated through ...
