Antibiotic resistance is a problem that impacts tens of millions of people each year worldwide. According to the CDC, "more than 2.8 million antibiotic-resistant infections occur in the United States each year, and more than 35,000 people die as a result." Drug-resistant infections are threatening advances in surgery, wound healing, cancer treatment, organ transplants and many other areas of...
Brook trout are disappearing from American streams. Amphibian habitats are changing. Coral species are dying.
The American River Basin in central California expects to see increasing temperatures and a declining snowpack through the end of the 21st century. The Bureau of Reclamation released the American River Basin Study today, which also found an increased variability of fall and winter precipitation that will amplify the severity of droughts and flooding in the basin. The report is available on...
Jennifer Choy makes atom-size antennas. They bear no resemblance to the telescoping rod that transmits pop hits through a portable stereo. But functionally, they're similar. They're quantum sensors, picking up tiny electromagnetic signals and relaying them in a way we can measure.
The Rutgers New Jersey Gun Violence Research Center has gathered data to determine how common gun ownership has become in New Jersey and how gun owners store and use their weapons.
Researchers have gained important insight into how the human brain processes an object in the visual system and where in the brain this processing takes place. The study shows people perceive objects differently depending on their prior knowledge and experience with that object.
St. Jude Global and international partners launched SAFER Ukraine to help Ukrainian children with cancer and blood disorders safely continue treatment, creating a model for how organizations can respond to other crises.
A person's blood type may be linked to their risk of having an early stroke, according to a new meta-analysis. The meta-analysis included all available data from genetic studies focusing on ischemic strokes, which are caused by a blockage of blood flow to the brain, occurring in younger adults under age 60.
In the last 50 years, oxygen-deficient zones in the open ocean have increased. Scientists have attributed this development to rising global temperatures: Less oxygen dissolves in warmer water, and the tropical ocean's layers can become more stratified.
Phosphorus is one of the elements that is crucial for the construction of organisms and their metabolism. Its cycle across the environments is also one of the best understood. However, it occurred to the Czech paleontologists Peter Kraft and Michal Mergl that there could still be some white spaces on the map of our understanding of such a fundamental process. Their publication, which takes a new...
Today it only takes one and a half hours to make a superconducting particle accelerator at the Department of Energy's SLAC National Accelerator Laboratory colder than outer space.
A French-Japanese research collaboration has fabricated metal nanocomposite coatings that improve the insulating properties of window glasses. The new coating prevents a significant portion of near-infrared (NIR) and ultraviolet rays (UV) from passing through, while at the same time admitting visible light. The findings were reported in the journal Science and Technology of Advanced Materials.
Researchers hope scaled-up version could one day generate oxygen to sustain humans on MarsAn instrument the size of a lunchbox has been successfully generating breathable oxygen on Mars, doing the work of a small tree.Since February last year the Mars oxygen in-situ resource utilisation experiment, or Moxie, has been successfully making oxygen from the red planet’s carbon dioxide-rich...
New research confirms that ethnicity is a risk factor for developing kidney disease in people with Type 1 diabetes. The findings also show people of African-Caribbean heritage and living with diabetes have nearly a 60 percent greater risk of advanced kidney disease.
A new method for correcting errors in the calculations of quantum computers potentially clears a major obstacle to a powerful new realm of computing.
The risk of children being orphaned per COVID-19 death is highest in the poorest countries and those where people of reproductive age have the highest rates of non-communicable diseases, according to a new study.
A review of 22 previously published studies suggests that taking micro-breaks -- discontinuing a task for periods of 10 minutes or less -- is generally associated with reduced fatigue and increased vigor.
A new study points to possible new treatments for chronic pain with a surprising link to lung cancer. Findings of the research, conducted in laboratory mouse models, open up multiple therapeutic opportunities that could allow the world to improve chronic pain management and eclipse the opioid epidemic.
The MOXIE experiment has now produced oxygen on Mars. It is the first demonstration of in-situ resource utilization on the Red Planet, and a key step in the goal of sending humans on a Martian mission.
Researchers have documented that corals can pass mutations acquired during their lifetimes to their offspring, providing increased genetic diversity for potential evolutionary adaptation.
Romanian research shows ‘micro-breaks’ of up to 10 minutes may help to reduce fatigueIt may not be long enough to pop to the shops or head out for a run, but taking a work break of less than 10 minutes could still boost wellbeing, research suggests.The team behind the analysis say “micro-breaks” appear to reduce fatigue and help workers feel more vigorous.
