Tech Xplore / A metamaterial that bridges air and water
Have you ever tried yelling underwater? Not only is it difficult to make the noise, but it is rarely audible to those outside of the water. Sound travels differently in mediums of different densities, and that causes a high ...
Tech Xplore / Energy-efficient process delivers rare-earth element for magnets
Neodymium is a rare-earth element essential for producing the strongest permanent magnets, which are widespread in defense technologies, hard drives, medical imaging devices, electric vehicle motors, wind turbines and more. ...
Medical Xpress / Consumers pay when drugmakers delay, finds study of over-the-counter drug exclusivity rules
Policies designed to encourage drugmakers to introduce over-the-counter (OTC) versions of previously prescription-only medications may in fact harm consumers, shows a new study co-authored by a University of Massachusetts ...
Tech Xplore / New ship hull modifications to slash fuel use
Researchers at MIT have demonstrated that wedge-shaped vortex generators attached to a ship's hull can reduce drag by up to 7.5%, which reduces overall ship emissions and fuel expenses. The paper, "Net Drag Reduction in High ...
Phys.org / Chemists pioneer light-driven macrolactone synthesis for fast route to complex natural compound
Macrolactones—large ring lactones—are core components of many natural products and pharmaceutical agents. Traditional synthetic routes rely on seco acids activated with condensing reagents, often requiring harsh conditions ...
Phys.org / Death may suggest we belong to a broader whole
Shisei Tei claims he is clumsy with technology and doesn't even own a smartphone, yet he has found himself thinking a lot about what we call generative AI.
Phys.org / Hubble seeks clusters in 'Lost Galaxy'
This NASA/ESA Hubble Space Telescope image features the spiral galaxy NGC 4535, which is situated about 50 million light-years away in the constellation Virgo (the Maiden). Through a small telescope, this galaxy appears extremely ...
Tech Xplore / Google's proposed data center in orbit will face issues with space debris in an already crowded orbit
The rapid expansion of artificial intelligence and cloud services has led to a massive demand for computing power. The surge has strained data infrastructure, which requires lots of electricity to operate. A single, medium-sized ...
Medical Xpress / Newly defined benign soft tissue tumor with bony shell may mimic malignancy
It's not often that a pathologist gets to make a diagnosis that works for the patient by preventing treatment from occurring. But thanks to a Johns Hopkins Medicine doctor and his newly reported definition and classification ...
Phys.org / Natural biliverdin analog from microalgae offers safer livestock feed alternative
Humans and farm animals share a common affliction: inflammation.
Tech Xplore / Yes, the government can track your location, but usually not by spying on you directly
If you use a mobile phone with location services turned on, it is likely that data about where you live and work, where you shop for groceries, where you go to church and see your doctor, and where you traveled to over the ...
Phys.org / Visual thinking: The strategy that could help you spot misinformation and manipulated images
A fake photo of an explosion near the Pentagon once rattled the stock market. A tearful video of a frightened young "Ukrainian conscript" went viral: until exposed as staged. We may be approaching a "synthetic media tipping ...
