A preclinical study shows that a specific human genetic variant of a receptor that stimulates insulin release may help individuals be more resistant to obesity. The researchers discovered that this variant behaves differently in the cell which may contribute to more efficient metabolism. Read more ›

Despite the Roman Empire's extensive military and cultural influence on the nearby Balkan peninsula, a DNA analysis of individuals who lived in the region between 1 and 1000 CE found no genetic evidence of Iron Age Italian ancestry. Instead, a new study has revealed successive waves of migrations from Western Anatolia, central and northern Europe, and the Pontic-Kazakh Steppe during the Empire's reign. Read more ›

On the highway of heat transfer, thermal energy is moved by way of quantum particles called phonons. But at the nanoscale of today's most cutting-edge semiconductors, those phonons don't remove enough heat. That's why researchers are focused on opening a new nanoscale lane on the heat transfer highway by using hybrid quasiparticles called 'polaritons.' Read more ›

A groundbreaking study suggests a class of medications used to treat type 2 diabetes may also reduce the risk of colorectal cancer (CRC). The findings support the need for clinical trials to determine whether these medications could prevent one of the deadliest types of cancers. Eventually, the medications may also show promise in warding off other types of cancer associated with obesity and diabetes. Read more ›

New research has found evidence that a novel stem cell treatment, using mRNA technology encapsulated into nanoparticles (LNP) that was successfully used to produce the COVID-19 vaccines, may boost the natural repair mechanism of the liver to regress the diseased tissue caused by either an acute or chronic liver injury. Researchers identified a specific receptor present on the stem cells which can be recognized and activated by the ligand protein... Read more ›

Comparing PET scans of more than 90 adults with and without mild cognitive impairment (MCI), researchers say relatively lower levels of the so-called 'happiness' chemical, serotonin, in parts of the brain of those with MCI may play a role in memory problems including Alzheimer's disease.

Researchers re-examined a plant fossil found decades ago in Colombia and realized that it wasn't a plant at all: it's a fossilized baby turtle. It's a rare find, because juvenile turtles' shells are soft and often don't fossilize well. Read more ›

The treatment of pancreatic cancer, an aggressive form of cancer associated with high mortality rates, is challenging owing to limited options and anticancer screening models. High mortality has been attributed to the unique tumor microenvironment (TME). Researchers have now created a pancreatic ductal adenocarcinoma (PDAC) organoid model using human-induced pluripotent stem cell (hiPSC) technology, simulating desirable TME properties. Their research findings have far-reaching consequences in the field of c Read more ›

Modern-day Ciudad Mante, Mexico, could help Tampa, Florida, plan for shifting water and electricity demands due to climate change, according to an international team of researchers. Researchers used utilities data and climate analogs -- contemporary cities with climates close to what other cities are predicted to experience in the future -- to assess how climate change may impact residential water and electricity use across 46 cities in the United States.

A new method can identify unique immune cell receptors and their location in tissue, a new study reports. The researchers predict that the method will improve the ability to identify which immune cells contribute to disease processes and open up opportunities to develop novel therapies for numerous diseases.

How heavy can an element be? An international team of researchers has found that ancient stars were capable of producing elements with atomic masses greater than 260, heavier than any element on the periodic table found naturally on Earth. The finding deepens our understanding of element formation in stars. Read more ›

Engineers have developed a bio-compatible ink that solidifies into different 3D shapes and structures by absorbing ultrasound waves. Because the material responds to sound waves rather than light, the ink can be used in deep tissues for biomedical purposes ranging from bone healing to heart valve repair. Read more ›

Scientists chipping away at one of the great challenges of metal-catalyzed C--H functionalization with a new method that uses a cobalt catalyst to differentiate between bonds in fluoroarenes, functionalizing them based on their intrinsic electronic properties. And their method is fast -- comparable in speed to those that rely on iridium. Read more ›

A study finds the greater honeyguide can learn distinct vocal signals to help people in Africa locate bee colonies. In parts of Africa, people communicate with a wild bird -- the greater honeyguide -- in order to locate bee colonies and harvest their stores of honey and beeswax. It's a rare example of cooperation between humans and wild animals, and a potential instance of cultural coevolution. Read more ›

An international consortium of geoscientists has reconstructed atmosphereric levels of CO2 going back 66 million years using proxies in the geoloogical record. Today's concenteration, 420 parts per million, is higher than it's ever been in 14 million years. Read more ›
