Biomedical engineers have demonstrated that one of the most dangerous mutations found in skin cancers might moonlight as a pathway to mending a broken heart. The genetic mutation in the protein BRAF, a part of the MAPK signaling pathway that can promote cell division, is one of the most common and most aggressive found in melanoma patients. In a new study, researchers show that introducing this mutation to rat heart tissue grown in a laboratory can induce growth.
An estimated 1,600 people in the U.S. contract a serious infection from Listeria bacteria in food each year and, of those individuals, about 260 people die, according to the Centers for Disease Control and Prevention. Researchers may now better understand how the bacteria, called Listeria monocytogenes, survive and persist in fruit-packing plants by evading and surviving sanitizers.
How does loss of habitat affect the animals still living there? A genetic study of saltwater-adapted Savannah sparrows around the San Francisco Bay Area shows that the 90% loss of tidal marsh habitat has led to more interbreeding with freshwater-adapted Savannah sparrows, diminishing their genetic adaptation to saltwater, such as enlarged kidneys and larger beak. This could lessen their ability to live in a saltwater habitat.
Model predictions showed a rapid increase in microplastic accumulation and contamination across the penguins' prey organisms resulting in Galapagos penguin showing the highest level of microplastics per biomass, followed by barracuda, anchovy, sardine, herring, and predatory zooplankton.
New research revealed a daily pattern wherein humpback whales move their singing away from shore throughout the day and return to the nearshore in the evening.
Computer scientists have invented a highly effective, yet incredibly simple, algorithm to decide which items to toss from a web cache to make room for new ones.
Researchers have made a pivotal discovery in the field of cellular microscopy. The team has successfully developed Two-Color Infrared Photothermal Microscopy (2C-IPM), a novel technology designed to investigate neutral lipids within lipid droplets of living cells. This new microscopy can be used with isotope labeling, which allows for the detailed monitoring of neutral lipid synthesis within individual lipid droplets.
Chopped carrot pieces are among the most universally enjoyed foods and a snacking staple -- a mainstay of school lunchboxes, picnics and party platters year-round. Now researchers have uncovered the secret science of prepping the popular root veg and quantified the processes that make them curl up if left uneaten for too long.
Researchers grew a twisted multilayer crystal structure for the first time and measured the structure's key properties. The twisted structure could help researchers develop next-generation materials for solar cells, quantum computers, lasers and other devices.
It's time to recognize the power of healthy forests in managing global growing flood risk, and to shift towards more sustainable forestry practices and policy.
Two research groups design a plasma (an ionized gas) reactor maintained by microwaves that makes it possible to decontaminate waters with high concentrations of dye.
A team has demonstrated new mechanisms that are involved in the development of inflammatory cardiovascular diseases.
Researchers found widespread overactivation in brain activity in unmedicated children with anxiety disorders. Treatment with cognitive behavioral therapy (CBT) led to improved clinical functioning and reduced activation in many brain areas. The findings illuminate the brain mechanisms underlying the acute effects of CBT to treat one of the most common mental disorders in children.
The way trees grow together do not resemble how branches grow on a single tree, scientists have discovered.
Scientists have found a way to reprogram T cells to fight aging. After using them to eliminate specific cells in mice, the scientists discovered they lived healthier lives and didn't develop aging-associated conditions like obesity and diabetes. Just one dose provided young mice with lifelong benefits and rejuvenated older mice.
More than half (51%) of respondents in a 2023 Harris Poll survey conducted on behalf of the American Heart Association did not identify heart disease as the leading cause of death in the U.S. Heart disease has been the leading cause of death in the U.S. for 100 years. Heart disease along with stroke, which is the fifth leading cause of death, claimed more lives in 2021 in the U.S. than all forms of cancer and chronic lower respiratory disease combined.
From misinformation and invisible cyber attacks, to irresponsible AI that could cause events involving multiple deaths, expert futurists have forecast how rapid technology changes may shape our world by 2040.
Scientists have called for simple, effective steps to cut the number of people bitten by venomous snakes.
MXene nanoparticle scaffolds have been shown to stimulate muscle growth, making them a promising option to treat muscle loss and damage. Now, researchers explain the molecular mechanisms behind their positive influence on muscle regeneration. This discovery can advance MXene scaffolds, potentially improving muscle reconstruction surgeries and establishing them as a standard medical practice for muscle recovery.
A new advancement in theoretical physics could, one day, help engineers develop new kinds of computer chips that might store information for longer in very small objects.
