Treating antibiotic-resistant infections with peptides inspired by human saliva

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...

American River Basin Study finds increasing temperatures will impact basin through rest of 21st century

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...

Engineering atomic antennas for quantum sensing

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.

What you know changes how you see things

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.

The story of evolution written in phosphorus

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...

Developing coating materials that could make windows better insulators

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.

Nasa’s Moxie instrument successfully makes oxygen on Mars

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...

Old drugs hint at new ways to beat chronic pain

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.

Short breaks can help boost energy at work, study suggests

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.
