The hidden role of the Milky Way in ancient Egyptian mythology
Astrophysicists shed light on the relationship between the Milky Way and the Egyptian sky-goddess Nut. The paper draws on ancient Egyptian texts and simulations to argue that the Milky Way might have shone a spotlight, as it were, on Nut’s role as the …
New 3D-printing method makes printing objects more affordable and eco-friendly
A team of scientists has unveiled a method for 3D printing that allows manufacturers to create custom-made objects more economically and sustainably.
Newly found genetic variant defends against Alzheimer’s disease
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.
New way to generate human cartilage
University of Montana researchers and their partners have found a new method to generate human cartilage of the head and neck.
New origin of deep brain waves discovered
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 …
Ants in Colorado are on the move due to climate change
Ant species living in Boulder’s foothills have shifted their habitat over the last six decades, potentially affecting local ecosystems, suggests a new study.
More than half a million global stroke deaths may be tied to climate change
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 th…
Mixed diets balance nutrition and carbon footprint
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 …
AI powered ‘digital twin’ models the infant microbiome
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, a…
Size of salty snack influences eating behavior that determines amount consumed
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 h…
Using CO2 and biomass, researchers find path to more environmentally friendly recyclable plastics
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.
How the body switches out of ‘fight’ mode
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…
New drug prevents flu-related inflammation and lung damage
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 faster, better way to prevent an AI chatbot from giving toxic responses
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.
