The health impacts of a complex protein that plays a major role in the development of Alzheimer's disease and heart conditions can be lessened by three kinds of drug inhibitors, according to scientists. Read more ›

It's no surprise that your dog can learn to sit when you say 'sit' and come when called. But a new study has made the unexpected discovery that dogs generally also know that certain words 'stand for' certain objects. When dogs hear those words, brain activity recordings suggest they activate a matching mental representation in their minds. Read more ›

Astronomers have identified what could be two of the Milky Way's earliest building blocks: Named 'Shakti' and 'Shiva', these appear to be the remnants of two galaxies that merged between 12 and 13 billion years ago with an early version of the Milky Way, contributing to our home galaxy's initial growth. The new find is the astronomical equivalent of archeologists identifying traces of an initial settlement that grew into a... Read more ›

Finding viable alternatives to traditional petroleum-based plastics and microplastics has never been more important. New research shows that their plant-based polymers biodegrade -- even at the microplastic level -- in under seven months. Read more ›

Researchers examined the developmental processes and reproduction-related behavior of 8 of the 11 families of Dermaptera (earwigs) in detail and compared with those reported in previous studies. The results confirmed that Dermaptera is a polyneopteran order, and the features such as caudal forceps and elaborate maternal care for eggs and young larvae emerged in parallel within the order during evolution.

The oldest Scandinavian bedrock was 'born' in Greenland according to a new geological study. The study helps us understand the origin of continents and why Earth is the only planet in our solar system with life. Read more ›

The dust of comets fills the space between the planets, collectively called the zodiacal cloud. Still, severe breakdown has reduced that dust in size so much that it now scatters sunlight efficiently, causing the faint glow in the night sky known as the 'zodiacal light.' It was long thought that high-speed collisions pulverized the comet ejecta, but now a team of researchers reports that heat is to blame. Read more ›

Aging may be less about specific 'aging genes' and more about how long a gene is. Many of the changes associated with aging could be occurring due to decreased expression of long genes, say researchers. A decline in the expression of long genes with age has been observed in a wide range of animals, from worms to humans, in various human cell and tissue types, and also in individuals with...

A group of coastal Alaska Native tribes in 2016 began monitoring shellfish, a traditional harvest, for deadly biotoxins because the state only tests commercial harvests. The program fills an essential gap in public health protection and has found success, with 17 tribes now in the testing network. Securing stable, long-term funding and improving public outreach could improve outcomes even further, a new study reports. Read more ›

Researchers have identified a mechanism that causes neurological problems in mice infected with SARS-CoV-2, the virus behind COVID-19. The researchers also found a treatment that helped prevent these changes. Read more ›

Artificial intelligence can spot COVID-19 in lung ultrasound images much like facial recognition software can spot a face in a crowd, new research shows. The findings boost AI-driven medical diagnostics and bring health care professionals closer to being able to quickly diagnose patients with COVID-19 and other pulmonary diseases with algorithms that comb through ultrasound images to identify signs of disease.

SARS-CoV-2, the virus that causes COVID-19, can damage the heart even without directly infecting the heart tissue, a new study has found. The research specifically looked at damage to the hearts of people with SARS-CoV2-associated acute respiratory distress syndrome (ARDS), a serious lung condition that can be fatal. But researchers said the findings could have relevance to organs beyond the heart and also to viruses other than SARS-CoV-2. Read more ›

With the rise in gestational diabetes and metabolic disorders during pregnancy, metformin is also being prescribed more frequently. Although it is known that the oral antidiabetic agent can cross the placental barrier, the impacts on the brain development of the child are largely unknown. Researchers have now been able to demonstrate in a mouse model that although metformin has positive effects in pregnant animals, it does not in the offspring. Read more ›

A group of high school students from Oakland, California, made contributions to the field of exoplanet research. Researchers worked with the students to use backpack-sized digital smart telescopes. These young citizen scientists played a role in observing and confirming the nature of a warm and dense sub-Saturn planet, known as TIC 139270665 b, orbiting a metal-rich G2 star. Read more ›
