India’s population is genetically one of the most diverse in the world, yet it remains underrepresented in global datasets. In a study publishing in the Cell Press journal Cell, researchers analyzed genomic data from more than 2,700 people from across India, capturing genetic variation from most geographic regions, linguistic groups, and communities. They found that most modern-day Indian people’s ancestry can be traced back to Neolithic Iranian farmers, Eurasian Steppe pastoralists, and South Asian hunter-gatherers.  “This ...

Sarcopenia, which is a progressive and extensive decline in muscle mass and strength, is common with aging and estimated to affect up to 50% of people aged 80 and older. It can lead to disability and injuries from falls and is associated with a lower quality of life and an increased mortality. Apart from lifestyle changes, there is no current clinical treatment for sarcopenia. Space flight with the associated absence of gravity and limited strain on muscles causes muscle weakness, a prominent feature of sarcopenia, within a short period of time, providing a time lapse view on age-related atrophy-associated ...

About The Study: In this cross-sectional study of opioid treatment programs (OTPs), although the availability of medications for opioid use disorder (MOUD) beyond methadone increased over time, most OTPs still did not offer all 3 forms of MOUD as of 2023. Specific organizational characteristics, such as being government operated and accepting Medicare, were associated with more comprehensive MOUD offerings. Future research should evaluate why OTPs vary in their MOUD offerings.  Corresponding Author: To ...

About The Study: In this cohort study of opioid-related index health care events, race and ethnicity–based and insurance-based disparities in access to medications for opioid use disorder persisted despite efforts to expand treatment availability.

Diatoms are some of the most common algae found in the ocean. There are at least 100,000 species. Most of these tiny diatoms use photosynthesis. This means that they use sunlight, carbon dioxide and water to produce the sugar and energy they need to grow, live and reproduce. However, some diatoms are different, such as the one with the not very catchy name of Nitzschia sing1. “These algae have stopped photosynthesising and started living off kelp,” explained Finn L. Aachmann, Professor at the Department of Biotechnology and Food Science at the Norwegian University ...

A new study challenges the idea that climate change is behind the recent erratic behavior of the polar jet stream, the massive current of Arctic air that regulates weather for much of the Northern Hemisphere. Large waves in the jet stream observed since the 1990s have, in recent years, driven abnormally frigid temperatures and devastating winter storms deep into regions such as the southern United States. Scientists fear that a warming atmosphere brought on by climate change is fueling these wild undulations, causing long troughs of bitter-cold air to drop down from the Arctic. But Dartmouth researchers report in AGU Advances ...

As wildfires increasingly threaten lives, landscapes, and air quality across the U.S., a Stanford-led study published in AGU Advances June 26 finds that prescribed burns can help reduce risks. The research reveals that prescribed burns can reduce the severity of subsequent wildfires by an average of 16% and net smoke pollution by an average of 14%. “Prescribed fire is often promoted as a promising tool in theory to dampen wildfire impacts, but we show clear empirical evidence that prescribed burning works in practice,” ...

PULLMAN, Wash.—When a team of scientists led by a Washington State University researcher examined the way that more than 9,400 children grew from toddlers to pre-adolescents, two distinct trajectories emerged. For most children, their body-mass index developed along a typical path: a drop in BMI following their first year, followed by a gradual increase after age 6. Eleven percent of the children, however, showed a very different pattern. These children—whose mothers were more likely ...

The use of AI image generation models has not only gained popularity but raised concerns surrounding potential misuse when it comes to training data, including copyright-protected material. Text-to-image models have gained significant popularity due to their ability to generate diverse, realistic-looking images from just a short prompt. As these models are trained on vast datasets from various sources, there is growing concern that artists’ works, including photographs, paintings and other creative pieces, may be used in training without their consent. To protect their work from being exploited by emerging technologies, artists have turned ...

WASHINGTON, D.C.— Compared with a Mediterranean diet, dietary acid load decreased significantly on a low-fat vegan diet and was associated with weight loss, according to a randomized cross-over trial conducted by the Physicians Committee for Responsible Medicine and published in Frontiers in Nutrition.   “Eating acid-producing foods like meat, eggs, and dairy can increase the dietary acid load, or the amount of acids consumed, causing inflammation linked to weight gain,” says Hana Kahleova, MD, PhD, director ...

In general, evolution is a long, slow process of tiny changes passed down over generations, resulting in new adaptations and even new species over thousands or millions of years. But when living things are faced with dramatic shifts in the world around them, they sometimes rapidly adapt to better survive. Scientists recently found an example of evolution in real time, tucked away in the collection drawers of the Field Museum in Chicago. By comparing the skulls of chipmunks and voles from the Chicagoland area collected ...
