In an era of dwindling glaciers, Southern Patagonia has managed to hold on to a surprising amount of its ice. But, a new study suggests that this protective effect might be pushed up against its limits soon. Read more ›

People who have had a stroke may be more likely to sleep too much or too little compared to those without prior stroke, according to a new study. The study does not prove that stroke causes abnormal sleep; it only shows an association. Read more ›

Researchers identified the first known microcin, a group of naturally produced antimicrobials, that targets the strains of bacteria that cause cholera. Read more ›

Astronomers have achieved a major breakthrough in solar physics by successfully producing detailed maps of the Sun's coronal magnetic fields. This milestone promises to enhance our understanding of the Sun's atmosphere and how its changing conditions lead to impacts on Earth's technology-dependent society. The corona, or the Sun's outer atmosphere, greatly influences solar winds and space weather events like solar flares and coronal mass ejections. However, the magnetic forces that... Read more ›

Researchers have developed a flexible, durable electronic prototype that can harvest energy from body heat and turn it into electricity that can be used to power small electronics, such as batteries, sensors or LEDs. This device is also resilient -- it still functions even after being pierced several times and then stretched 2,000 times. Read more ›

Atrial fibrillation, a rapid, irregular heart beat that can lead to stroke or sudden death, is three times more common than previously thought, affecting nearly 5% of the population, or 10.5 million U.S. adults, according to new estimates. Read more ›

Researchers have created microscale robots less than 1 millimeter in size that are printed as a 2D hexagonal 'metasheet' but, with a jolt of electricity, morph into preprogrammed 3D shapes and crawl. Read more ›

A new study reveals that stress-induced changes in sperm motility occur after a stressful event, rather than during it and improves sperm performance. The discovery is essential in understanding how stress impacts the reproductive process to improve fetal development outcomes. Read more ›

The team first looked at variation in data from genetic sequencing of 106,973 post-menopausal female participants in the UK Biobank study. Researchers focused on rare types of genetic changes which cause a loss of the protein, and investigated their effect on the timing of menopause. The genetic changes studied are all rare in the population, however their influence on menopause is five times greater than the impact of any previously... Read more ›

Researchers have demonstrated that bluestreak cleaner wrasse (Labroides dimidiatus) checked their body size in a mirror before choosing whether to attack fish that were slightly larger or smaller than themselves, saying it was the first time for a non-human animal to be demonstrated to possess some mental states that are elements of private self-awareness.

Neanderthal remains recently discovered in a cave in France support well-known theory of why the Neanderthals became extinct, researchers behind a new study say. Read more ›

Many clinical trials of new cancer drugs may be inappropriately excluding some people with Duffy-null phenotype, a trait found predominantly in people of African or Middle Eastern descent, researchers report in a new study. Read more ›

It's a dogma taught in every introductory biology class: Proteins are composed of combinations of 20 different amino acids, arranged into diverse sequences like words. But researchers trying to engineer biologic molecules with new functions have long felt limited by those 20 basic building blocks and strived to develop ways of putting new building blocks -- called non-canonical amino acids -- into their proteins. Now, scientists have designed a new... Read more ›

Researchers have for the first time identified degeneration-associated 'molecular markers' -- observable changes in cells and their gene-regulating networks -- that are shared by several forms of dementia that affect different regions of the brain. Critically, the research also identified markers specific to different forms of dementia, and the combined findings represent a potential paradigm shift in the search for causes, treatments and cures.

The frequency of second primary malignancies (SPMs) arising in cancer survivors following treatment with CAR T-cell therapy was statistically comparable to the frequency of SPMs following other standard-of-care therapies, according to a systematic review and meta-analysis. Read more ›

Researchers have succeeded in combining two major research fields in photonics by creating a nano-object with unique optical qualities. Since the object is a thousand times thinner than the human hair, yet very powerful, the breakthrough has great potential in the development of efficient and compact nonlinear optical devices.

Since their invention in the 1920s, jungle gyms and monkey bars have become both fixtures of playgrounds and symbols of childhood injury that anxious caretakers want removed. Anthropologists mark 100 years of the iconic playground equipment by arguing that risky play exercises a biological need passed on from apes and early humans for children to independently test and expand their physical and cognitive abilities in a context in which injury...

Most atoms are made from positively charged protons, neutral neutrons and negatively charged electrons. Positronium is an exotic atom composed of a single negative electron and a positively charged antimatter positron. It is naturally very short-lived, but researchers have now successfully cooled and slowed down samples of positronium using carefully tuned lasers. They hope this research will help others explore exotic forms of matter, and that such research might unlock... Read more ›
