Lecanemab, sold as Leqembi, is a monoclonal antibody treatment for Alzheimer’s disease that targets and eliminates harmful amyloid plaques while slowing cognitive decline. Scientists from VIB and the University of Leuven have figured out exactly how it works. Their research shows that specific parts of antibodies, known as “Fc fragments,” are important in activating the brain’s immune cells, microglia, which then begin to clear these toxic deposits. This study provides the first clear explanation of how this type of therapy works, answers long-standing questions, and provides guidance for developing safer and more effective treatments for Alzheimer’s disease. The results of…

Generative artificial intelligence programs can be written fluently, but basic scientific descriptions remain difficult to accurately and consistently evaluate. Recent research shows that if you ask artificial intelligence the exact same question multiple times, it often returns completely different answers. These results are rutgers business reviewhighlighting the limitations of current automated reasoning and the continued need for human oversight. Generative artificial intelligence is a type of technology that is trained on large text databases to generate human-like sentences. Today, millions of people use these applications every day for everything from marketing to software development. The software writes in an authoritative…

Listeria monocytogenes is the third leading cause of death from a bacterial foodborne pathogen in the United States, and pregnant people bear a disproportionate share of the burden. However, the scientific models used to develop food safety policy are rarely designed specifically with pregnant people in mind. A new study published in the journal Risk Analysis aims to change that. Each year, approximately 1,250 Americans contract listeriosis, the disease caused by Listeria monocytogenes. The hospitalization rate for this disease is a staggering 86%, and approximately 14% of cases are fatal. For pregnant people, the risk is even higher. Pregnancy-related cases…

Finding effective treatments for osteosarcoma, the most common osteosarcoma in children and young adults, has puzzled medical researchers for 40 years. Now, a new study by researchers at Case Western Reserve University and University Hospitals shows some promising results. This research BMC Medicine, Researchers have discovered that a specially designed immune cell therapy called OSM CAR-T successfully attacks osteosarcoma tumors in a mouse model. According to the Osteosarcoma Institute, osteosarcoma occurs primarily in children, teens, and young adults during periods of rapid bone growth, and approximately 1,000 new cases are diagnosed each year nationwide. The cause is unknown, but is…

The smoking rate among U.S. adults will fall below 10% in 2024 for the first time in recorded history. That in itself is a big deal. It is also worth noting that everyone is starting to know about it. Reports of historic declines in smoking rates did not come from the U.S. government, which was collecting the data. Instead, the news came through an analysis of the digital journal NEJM Evidence by Israel Agak, founder and CEO of research technology company Chisquares. Typically, the U.S. government is responsible for analyzing national survey data on tobacco use and publishing the results.…

Exposure to per- and polyfluoroalkyl substances (PFAS) during childhood can affect bone development in children during adolescence, according to a new study published in . Journal of the Endocrine Society.PFAS are synthetic chemicals found in water, food, and everyday products. Many of these “permanent chemicals” remain in the environment and in the human body and can interfere with normal development, such as bone growth.”Adolescence is a critical period for building strong bones, and achieving optimal bone mass during this period can reduce the lifelong risk of fractures and osteoporosis,” said Dr. Jesse P. Buckley of the UNC Gillings School of…

Although it is widely known that obesity increases the risk of diabetes and cardiovascular disease, the negative effects on the skeleton are often overlooked. Excess body fat can impede bone metabolism, weaken bone quality, and impede fracture repair. In people with metabolic disorders, fat cells accumulate in the bone marrow, which can interfere with the activity of bone-forming cells and damage the network of blood vessels that support skeletal tissues. These changes increase the risk of fractures and reduce the body’s ability to regenerate bone after injury. Despite these clinical challenges, the biological mechanisms linking metabolic diseases and bone health…

aAfter Russia’s full-scale invasion of Ukraine in 2022, millions of people in Pakistan suffered repeated power outages after the price of liquefied natural gas soared to record highs.. A severe heat wave and gas shortage caused by record price hikes caused power outages across the country.However, people soon began to realize that there was an alternative. The falling cost of solar panels and generous government incentives to feed excess power back into the grid have made rooftop solar an attractive option.”At the time, people who could afford to invest realized that it was much cheaper, more cost-effective, and better in…

Measures of vascular health from routine blood pressure measurements may help identify adults at high risk for dementia, according to research presented at the American College of Cardiology’s Annual Scientific Sessions (ACC.26). The results of two studies that tracked patterns of arterial stiffness over time are consistent with growing evidence that uncontrolled high blood pressure accelerates the aging and stiffening of blood vessels and contributes to the development of dementia. As the population ages, the rates of dementia and age-related cognitive decline are expected to increase. At the same time, almost half of adults in the United States have high…
