Absorbing excess sound to make public environments like theaters and concert halls safer for hearing and using the unwanted sound waves to create electricity is the aim of a new paper. The authors built a system of piezoelectric sensors that can be installed in walls, floors, and ceilings to absorb sound waves and collect their energy. They used computer simulations to fine-tune variables including the voltage needed to power the... Read more ›

Chemists bring fresh insight into the development of semiconductor materials that can do things their traditional silicon counterparts cannot -- harness the power of chirality, a non-superimposable mirror image. Read more ›

Far from being stiff and pointy, a coronavirus's infectious spikes are shaped like chicken drumsticks with the meaty part facing out, and the meaty part can tilt every which way on its slender stalk. A new study suggests that disabling those hinges could block infection. Read more ›

The one thing everyone knows about black holes is that absolutely everything nearby gets sucked into them. Almost everything, it turns out. Astrophysicists have now determined conclusively that energy close to the event horizon of black hole M87* is pushing outward, not inward. The researchers have also created a way to test the prediction that black holes lose rotational energy and to establish it's that energy that produces the incredibly... Read more ›

Hormonal contraceptives taken by adolescents may influence development of the brain in a way that alters the recognition of risks, a new study in rats suggests. Read more ›

The Arctic is currently warming nearly four times faster than the global average rate. The new study aimed to estimate the impact of this faster warming on how quickly the global temperature thresholds of 1.5C and 2C, set down in the Paris Agreement, are likely to be breached. Read more ›

Researchers aiming to combat rising global temperatures have developed a new 'cooling glass' that can turn down the heat indoors without electricity by drawing on the cold depths of space. The new technology, a microporous glass coating, can lower the temperature of the material beneath it by 3.5 degrees Celsius at noon, and has the potential to reduce a mid-rise apartment building's yearly carbon emissions by 10 percent.

Intratumoral therapy -- in which cancer drugs are injected directly into tumors -- is a promising treatment option for solid cancers but has shown limited success in clinical trials due to an inability to precisely deliver the drug and because most immunotherapies quickly dissipate from the site of injection. A team of researchers has developed a gel delivery system that overcomes these challenges. The gel is injectable but solidifies upon... Read more ›

Astronomers have detailed radio observations of an extraordinary aurora-like display -- occurring 40,000 km above a relatively dark and cold patch on the Sun, known as a sunspot. Read more ›

A new study has revealed that water from the Earth's surface can penetrate deep into the planet, altering the composition of the outermost region of the metallic liquid core and creating a distinct, thin layer. Illustration of silica crystals coming out from the liquid metal of the Earth's outer core due to a water-induced chemical reaction.

An intensive three-year intervention to lower the top blood pressure number to less than 120 mm Hg was more effective at preventing death, heart attack, stroke and other cardiovascular events in adults at high risk for cardiovascular disease, compared to the standard treatment target of under 140 mm Hg, according to new research.

A new study has found that one in five individuals taking Nirmatrelvir-ritonavir therapy, commonly known as Paxlovid, to treat severe symptoms of COVID-19, experienced a positive test result and shedding of live and potentially contagious virus following an initial recovery and negative test -- a phenomenon known as virologic rebound. By contrast, people not taking Paxlovid only experienced rebound about 2 percent of the time. Read more ›

In the 1800s, some of the strongest earthquakes in recorded U.S. history struck North America's continental interior. Almost two centuries later, the central and eastern United States may still be experiencing aftershocks from those events, a new study finds. Read more ›

The odds of prescribing the appropriate dose of statins -- a medicine used to lower 'bad' cholesterol levels -- increased sixfold when automated referrals were made to pharmacy services, instead of relying on traditional prescribing methods. More than 90 million people in the U.S. use statins, making it one of the most prescribed medications in the country. Despite their effectiveness in lowering cholesterol levels and the risk of cardiovascular diseases,... Read more ›

Scientists have discovered two enzymes that enable bacteria to target and break up DNA. This chemical defense likely evolved to help the organism fight off germs. The chemical riches were found within the institute's one-of-a-kind Natural Products Discovery Center collection.  Read more ›

An international team of researchers has developed a handheld, non-invasive device that can detect biomarkers for Alzheimer's and Parkinson's Diseases. The biosensor can also transmit the results wirelessly to a laptop or smartphone. The team tested the device on in vitro samples from patients and showed that it is as accurate as the state of the art method. Ultimately, researchers plan to test saliva and urine samples with the biosensor.... Read more ›

Banding together to sell fishing rights could generate economic benefits for African countries, which receive far less from access to their fisheries on the global market than other countries do from theirs. By joining forces, researchers say African fisheries would not just secure more competitive access fees, they could also protect their seas' biodiversity. Read more ›
