A team of scientists has unveiled a method for 3D printing that allows manufacturers to create custom-made objects more economically and sustainably.
Neuroscientists have identified a genetic mutation that fends off Alzheimer's disease in people at high risk and could lead to a new way to protect people from the disease.
University of Montana researchers and their partners have found a new method to generate human cartilage of the head and neck.
Biomedical engineering researchers have uncovered a previously unknown source of two key brain waves crucial for deep sleep: slow waves and sleep spindles. Traditionally believed to originate from one brain circuit linking the thalamus and cortex, the team's findings suggest that the axons in memory centers of the hippocampus play a role.
Ant species living in Boulder's foothills have shifted their habitat over the last six decades, potentially affecting local ecosystems, suggests a new study.
A changing climate may be linked to growing death and disability from stroke in regions around the world, according to a new study. Researchers found over three decades that non-optimal temperatures, those above or below temperatures associated with the lowest death rates, were increasingly linked to death and disability due to stroke. The study does not prove that climate change causes stroke. It only shows an association. The study also did not examine other risk factors such as high blood pressure and high cholesterol levels.
What we eat can impact our health as well as the environment. Many studies have looked at the impacts of diets in very general terms focused at the level of food groups. A new study explores this issue following a more nuanced dish-level approach. One of the benefits of this kind of study is that people's connections with their diets vary around the world and have strong cultural associations. Knowledge of the impacts of diets using dishes rather than broad food groups can help individuals make informed choices and those in the food industry improve their practices.
Researchers have developed a new generative artificial intelligence (AI) tool that models the infant microbiome. This 'digital twin' of the infant microbiome creates a virtual model that predicts the changing dynamics of microbial species in the gut, and how they change as the infant develops.
The size of an individual snack piece not only influences how fast a person eats it, but also how much of it they eat, according to a new study. With nearly a quarter of daily calorie intake in the United States coming from snacks, these findings may have implications for helping people better understand how eating behavior impacts calorie and sodium intake.
Researchers have created a potential alternative to traditional petroleum-based plastic that is made from carbon dioxide (CO2) and lignin, a component of wood that is a low-cost byproduct of paper manufacturing and biofuel production.
Cortisone and other related glucocorticoids are extremely effective at curbing excessive immune reactions. But previously, astonishingly little was known about how they exactly do that. Researchers have now explored the molecular mechanism of action in greater detail. As the researchers report, glucocorticoids reprogram the metabolism of immune cells, activating the body's natural 'brakes' on inflammation. These findings lay the groundwork for development of anti-inflammatory agents with fewer and less severe side effects.
Findings show a newly created drug can prevent runaway inflammation while still allowing the immune system to handle the virus, even when given late into infection.
A new technique can more effectively perform a safety check on an AI chatbot. Researchers enabled their model to prompt a chatbot to generate toxic responses, which are used to prevent the chatbot from giving hateful or harmful answers when deployed.
CAR T cell therapy has revolutionized the way certain types of cancer are treated, and the longer those CAR T cells live in a patient's body, the more effectively they respond to cancer. Now, researchers have found that a protein called FOXO1 improves the survival and function of CAR T cells, which may lead to more effective CAR T cell therapies and could potentially expand its use in difficult-to-treat cancers.
Cells contain various specialized structures -- such as the nucleus, mitochondria or peroxisomes -- known as 'organelles'. Tracing their genesis and determining their structure is fundamental to understanding cell function and the pathologies linked to their dysfunction.
A new study reveals the detailed protein structure of the TAS2R14, a bitter taste receptor that allows us to perceive bitter taste. In addition to solving the structure of this taste receptor, the researchers were also able to determine where bitter-tasting substances bind to TAS2R14 and how they activate them. The findings may lead to the development of drugs that targeting taste receptors.
The potential of quantum technology is huge but is today largely limited to the extremely cold environments of laboratories. Now, researchers have succeeded in demonstrating for the very first time how laser light can induce quantum behavior at room temperature -- and make non-magnetic materials magnetic. The breakthrough is expected to pave the way for faster and more energy-efficient computers, information transfer and data storage.
Forests could also be potential bulwarks against climate change. But, increasingly severe droughts and wildfires, invasive species, and large insect outbreaks -- all intensified by climate change -- are straining many national forests and surrounding lands in the United States. A report outlines a new approach to forest stewardship that 'braids together' Indigenous knowledge and Western science to conserve and restore more resilient forestlands.
Undertaking the majority of daily physical activity in the evening is linked to the greatest health benefits for people living with obesity, according to researchers who followed the trajectory of 30,000 people over almost 8 years.
Over 12 million people worldwide suffer from a chronic infection with the hepatitis D virus. This most severe viral liver disease is associated with a high risk of dying from liver cirrhosis and liver cancer. It is caused by the hepatitis D virus (HDV), which uses the surface proteins of the hepatitis B virus (HBV) as a vehicle to specifically enter liver cells via a protein in the cell membrane -- the bile salt transporter protein NTCP.
