Fireworks may dazzle crowds with brilliant colors and loud explosions, but new research suggests their effects continue long after the show ends. Three recent studies published in American Chemical Society (ACS) journals examined what fireworks leave behind, from discarded debris and airborne particles to chemical compounds released into the atmosphere.…
Recent research from the University of Massachusetts Amherst suggests that using alcohol to cope with stress in early adulthood may have lasting effects on the brain that do not disappear with years of sobriety. The study found that these changes can begin to surface by middle age, reducing mental flexibility,…
Some people remain mentally sharp even though their brains contain the biological changes associated with Alzheimer’s disease. A new study from the Netherlands Institute for Neuroscience suggests that the answer may lie in how a rare group of brain cells, called immature neurons, responds to damage. The findings offer new…
As carbon dioxide (CO2) emissions continue to climb, interest in geoengineering is growing as governments, researchers, and environmental advocates search for ways to limit the worst effects of climate change. These large scale climate interventions could influence rainfall, agriculture, and ecosystems around the world, making their potential benefits and risks…
Scientists have developed a new way to control quantum systems that can make their behavior appear more consistent with time moving backward rather than forward. The research, published in Physical Review X, introduces quantum control protocols that reshape a system’s “arrow of time,” the concept that time naturally moves in…
Scientists have uncovered evidence that could change how doctors think about a common form of stroke and why standard preventive treatments often fail. New research suggests that lacunar ischemic stroke is not primarily caused by fatty plaque building up inside arteries, as many have assumed. Instead, the strongest link appears…
Primordial black holes have remained one of astronomy’s most intriguing ideas for decades. Now, researchers at the University of Miami believe a recent gravitational wave detection may bring scientists closer to confirming that these ancient objects are real, a breakthrough that could also help solve the enduring mystery of dark…
Bumble bees have demonstrated an impressive ability that scientists once believed was limited to humans and other animals with much larger brains. In a new study, the insects successfully completed a completely unfamiliar object manipulation task despite never being taught how to solve it. The findings challenge a long-standing belief…
Modern weight loss medications have transformed obesity treatment, helping many people lose significant amounts of weight. But these drugs often come with an important drawback: They can also reduce muscle mass. Now, researchers have uncovered a biological mechanism that may one day help address that challenge while also boosting the…
Excessive blood loss is the leading cause of death from combat injuries, making rapid bleeding control one of the biggest challenges in battlefield medicine. Researchers at KAIST, including an Army Major, have developed a next generation spray-on powder that can stop severe bleeding in about one second. The innovation could…
A leading climate scientist is pushing back against what he describes as “demonstrably incorrect” claims in a major US government climate report, arguing that it misrepresented his research and understated the role of human activity in global warming. Prof Benjamin Santer, an Honorary Professor at the University of East Anglia…
A team of physicists has overcome a major obstacle in quantum computing by dramatically increasing the lifetime of magnons, tiny magnetic waves that can carry quantum information. The researchers extended their lifespan from just a few hundred nanoseconds to as long as 18 microseconds, nearly 100 times longer than previously…
Scientists at Southwest Research Institute (SwRI) have taken a new look at Earth’s violent beginnings and found that ancient asteroid impacts may have played a key role in making the planet habitable. Their computer models suggest that repeated collisions did far more than reshape the young Earth’s surface. They also…
Scientists at the University of Glasgow are celebrating the release of a massive new catalog of gravitational wave detections that marks another major step forward for gravitational wave astronomy. The newly published Gravitational Wave Transient Catalogue-5.0 (GWTC-5) has been released online, with companion research papers submitted to Astrophysical Journal and…
