The first all-female spacewalk is back on, six months after a flap over spacesuits led to an embarrassing cancellation.
A federal agency has rejected an iconic Alaska tree for listing as a threatened species due to climate warming.
Researchers have developed a new non-invasive optical imaging system that promises to improve diagnosis and treatments for dry eye disease. Dry eye, which often causes irritation and blurred vision, occurs when there is instability in the inner layer of the tear film that protects the outside of the eye.
Over the last two decades, tremendous advances have been made in the field of quantum information science. Scientists are capitalizing on the strange nature of quantum mechanics to solve difficult problems in computing and communications, as well as in sensing and measuring delicate systems. One avenue of research in this field is optical quantum information processing, which uses photons—tiny...
Fish use colorful patterns to signal to each other, including advertising for mates and warding off rivals. Studying these colors, especially in small and squirmy species, sometimes entails anesthetizing and photographing the fish to obtain color measurements from digital images.

A 5-minute soak in a 40% solution of household bleach decontaminated stainless steel wires coated with chronic wasting disease (CWD) prions, according to a new study. The scientists used the wires to model knives and saws that hunters and meat processors use when handling deer, elk and moose - all of which are susceptible to CWD.
Shift work and jet lag disrupt not just sleep cycles, but feeding and digestive cycles as well. Such disruptions have been linked to risk of obesity, inflammatory bowel disease, infection, and other conditions. Now, researchers have identified an immune cell that helps set the daily rhythms of the gut. The findings open the door to new treatments for digestive ailments targeting such cells.
A team led by scientists has designed and tested a 3D-printed metamaterial that can manipulate light with nanoscale precision. Their designed optical element focuses light to discrete points in a 3D helical pattern.
The research vessel is spearheading the biggest ever scientific expedition at the North Pole.
An ingestible sensor that allows doctors to remotely monitor tuberculosis patients' intake of medication has the potential to save millions of lives and revolutionise treatment for the world's most deadly infectious disease, researchers said Friday. A randomised trial of 77 patients in California, published in the journal PLOS medicine, found that 93 percent of patients using the sensor were...
Bans on the technology have mostly focused on law enforcement, but there’s a growing movement to get it out of school, parks, and private businesses too.
A team led by scientists at the University of Washington has designed and tested a 3-D-printed metamaterial that can manipulate light with nanoscale precision. As they report in a paper published Oct. 4 in the journal Science Advances, their designed optical element focuses light to discrete points in a 3-D helical pattern.
Researchers found that aggressive breast cancers store glycogen in very large amounts, offering an explanation of how cells can change their function to evade treatment, grow and spread. Targeting an enzyme involved in this process could potentially treat or prevent metastases.
