Medical Xpress / Blood pressure drug effective for treating antibiotic-resistant bacteria, study finds
Infections from antibiotic-resistant bacteria are difficult to treat and are responsible for over 2.8 million infections and more than 35,000 deaths in the U.S. each year. A new study in Nature Communications reports that ...
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 / Chernobyl's radioactive landscape is testament to nature's resilience and survival spirit
On contaminated land that is too dangerous for human life, the world's wildest horses roam free.
Medical Xpress / Researchers use statistics and math to understand how the brain works
Nothing rivals the human brain's complexity. Its 86 billion neurons and 85 billion other cells make an estimated 100 trillion connections. If the brain were a computer, it would perform an exaflop (a billion-billion) mathematical ...
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 ...
Medical Xpress / Cannabis legalization spurs innovation, but not always in ways that benefit patients or public health
Innovation in health care saves lives. But not all health innovations have enough evidence to actually benefit patients.
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 ...
Dialog / Generalized optical meta-spanners empower arbitrary light paths for multitasking optical manipulation
Have you ever wished to drive microscopic matter along an arbitrarily tailored trajectory instead of just a circle? That's exactly what we set out to achieve.
Phys.org / Wildfires used to 'go to sleep' at night. Climate change is turning them into prime burning hours
Burning time for North American wildfires is going into overtime. Flames are lasting later into the night and starting earlier in the morning because human-caused climate change is extending the hotter and drier conditions ...
