Northeast Greenland is home to the 79 N Glacier -- the country's largest floating glacier tongue, but also one seriously threatened by global warming: warm water from the Atlantic is melting it from below. Experts have however now determined that the temperature of the water flowing into the glacier cavern declined from 2018 to 2021, even though the ocean has steadily warmed in the region over the past several decades....

Climate scientists and permafrost experts show that, according to new climate computer model simulations, global warming will accelerate permafrost thawing and as a result lead to an abrupt intensification of wildfires in the Subarctic and Arctic regions of northern Canada and Siberia. Read more ›

Analyzing fossils can be difficult -- especially when they're so small that they can only be seen with a microscope. Researchers have now come up with a solution. Read more ›

The tiered umbrella is one of Thailand's oldest and most sacred ornamental symbols. Constructing one of these ornate pieces, also called chatras, can take master artisans up to six months. However, researchers demonstrate a technique for constructing seven-tiered umbrellas using high-powered lasers, which dramatically reduces the production time. Employing carbon dioxide lasers, they were able to fashion umbrellas from stainless steel in a matter of days while preserving their intricate... Read more ›

A new study has revealed that despite the recent pandemic, outbreak detection efforts remain under-resourced in South and Southeast Asia, with only about half the countries reviewed having integrated pathogen genomic surveillance initiatives in their national plans. The study also identifies key priorities to enhance the preparedness of the region against future pandemics. Read more ›

Cancer incidence trends in 2021 largely returned to what they were before the COVID-19 pandemic, according to a study by researchers at the National Institutes of Health (NIH). However, there was little evidence of a rebound in incidence that would account for the decline in diagnoses in 2020, when screening and other medical care was disrupted. One exception was breast cancer, where the researchers did see an uptick in diagnoses... Read more ›

Parkinson's disease, a debilitating nervous system disorder, is treated with medications that sometimes cause impaired decision-making and poor impulse control. Now, researchers have identified a structure in the brain called the external globus pallidus which may be responsible for this side effect, paving the way for new treatments. Read more ›

With strong bactericidal properties, graphene has the potential to become a game changer in the fight against antibiotic-resistant bacteria. So far there have been no efficient ways to control these properties -- and thus no way to make use of graphene's potential in healthcare. Now researchers have solved the problem by using the same technology found in an ordinary fridge magnet. The result of which, is an ultra-thin acupuncture-like surface... Read more ›

Ammonia (NH3) can be decomposed to produce hydrogen gas without releasing CO2. The ease of transport and high hydrogen density make it valuable for the green energy industry. A drawback of using NH3 is that it requires very high temperatures for decomposition reactions. Researchers have now presented a surface protonics-assisted method for the on-demand production of green hydrogen from ammonia using an electric field and Ru/CeO2 catalyst. Read more ›

Scientists have uncovered critical differences between how innate-like T cells mature in humans and mice. Early in life, most innate-like T cells in the human thymus aren't able to use all of their immune abilities. The discovery could point to better preclinical studies and, perhaps someday, a new form of immunotherapy. Read more ›

It's almost time to dust off the Halloween decorations and adorn the house with all manner of spooky things, including the classic polyester spider webs. Scientists have made their own version of fake spider silk, but this one consists of proteins and heals wounds instead of haunting hallways. The artificial silk is strong enough to be woven into bandages that helped treat joint injuries and skin lesions in mice. Read more ›

Artificial coastlines, including human-made dikes and other engineered constructions, can help prevent erosion and protect from storms and flooding. However, ecological functions remain unprotected from many of these structures. So researchers in China have investigated the use of specialized types of cement. The team started with a limestone and clay cement that hardens underwater and then added polyacrylamide and chitosan. The two treatments were mixed into the cement to form... Read more ›
