A new review suggests that the menopausal transition represents a critical period for Alzheimer’s disease prevention in women, potentially shifting focus to early detection, gender-specific risk factors, and more personalized care. Expert review: Women’s midlife: The front lines of Alzheimer’s disease prevention. Image credit: izzuanroslan / Shutterstock In a recent review published in clinical research journalLisa Mosconi, Ph.D., author of Neuroscientist and women’s brain health expert, investigated how midlife hormonal changes and neuroendocrine aging influence Alzheimer’s disease (AD) risk in women and identified opportunities for gender-specific early prevention strategies. Why are women at higher risk of Alzheimer’s disease? Almost two-thirds…

The Nanomedicine and Nanotoxicology Group (GNano) at the São Carlos Physics Institute of the University of São Paulo (IFSC-USP) in Brazil has discovered a way to convert the bioceramic material hydroxyapatite into nanoparticles with enhanced intrinsic luminescence. This paves the way for the use of biocompatible and low-cost nanomaterials in biomedical imaging techniques. “We have demonstrated that incorporating carbonate groups into the hydroxyapatite structure increases the concentration of crystal defects, which is responsible for increasing the material’s intrinsic luminescence. After functionalization with citrate, which improves colloidal stability in aqueous media, these calcium phosphate nanoparticles can be used as a luminescent…

When part of the small intestine becomes diseased or dies, surgeons often have to remove the damaged tissue. This surgery, known as radical small bowel resection, can save lives. However, this has a major drawback. Many patients subsequently develop serious liver problems, including liver failure that requires long-term damage and transplantation. Currently, no drugs exist to prevent or treat this complication, which affects up to 15% of patients after surgery. Researchers at Washington University School of Medicine in St. Louis developed a new compound and tested it in mice. Their findings suggest that the drug may protect the liver while…

The first large-scale analysis of multiple types of cancer in cats has revealed genetic changes that could guide new treatments for both animals and humans. Researchers examined tumors taken from about 500 pet cats from five countries. The study involved scientists from the Wellcome Sanger Institute, Canada’s Ontario Veterinary College, the University of Bern, and other collaborators. By studying these samples, the research team identified the key genetic changes that cause cancer in cats and found that many of these changes are very similar to those seen in human cancers. Environmental risks and genetic overlap Cats often share the same…

Many teenagers looking to manage their weight are turning to artificial intelligence chatbots to create personalized diet plans. However, a new study has been published Frontiers of nutrition It has become clear that these computer-generated menus often lack basic calories and do not provide the right balance of essential nutrients. Following these flawed digital recommendations can put young people at risk of malnutrition during a period of rapid physical growth. Childhood and adolescent obesity rates are rising rapidly around the world. This condition carries immediate and long-term health risks, including an increased chance of developing type 2 diabetes, high blood…

In Japan, many older adults rely on bicycles for daily transportation, much more than older adults in Europe or the United States. Previous research has shown that people who ride bicycles tend to be more physically active and socially engaged. Cycling has long been thought to be a habit that reduces the need for long-term care and lowers the risk of death, but there is little long-term evidence validating these benefits, particularly in Japan. To better understand these effects, researchers analyzed older adults’ cycling habits across two key areas. First, they looked at how often participants cycled in 2013, and…

Recent research published in journals autism research Studies suggest that cannabidiol oil may help improve certain social behaviors and reduce anxiety in children with autism. Although the treatment did not significantly change key measures of broad social communication, the findings provide evidence that the treatment may alleviate certain daily challenges and reduce parents’ stress levels. Currently, there are no approved treatments specifically designed to help with the social difficulties associated with autism. When doctors prescribe drugs to manage related behavioral problems, the drugs often have unwanted side effects. In the absence of such safe options, parents and medical professionals are…

House Democrats on Wednesday proposed a bill through the One Big Beautiful Bill Act that would restore clean energy tax credits that Republicans canceled last year. The Energy Bill Relief Act, signed by more than half of House Democrats (122 total), aims to establish new incentives for renewable projects and protect consumers from rising electricity prices due to grid demand from large energy users such as data centers. In addition to reincreasing clean energy credits introduced in the Inflation Control Act of 2022, the sweeping bill would restore subsidies for renewable energy projects that the Trump administration ended and authorize…

A federal court’s decision to dismiss a lawsuit alleging that U.S. regulators failed to prevent widespread contamination of agricultural land with toxic PFAS chemicals is based on a “misinterpretation” of the Clean Water Act and creates “dangerous real-world consequences for public health,” watchdog groups argue in a new court filing. The appeal by Public Employees for Environmental Responsibility (PEER) is the latest move in the fight over policy issues surrounding sewage sludge pollution. In 2024, PEER sued the Environmental Protection Agency (EPA) on behalf of two Texas farming families who experienced health problems after their property was contaminated with perfluoroalkyl…

Research with full-time employed individuals reveals that narcissists’ unethical behavior is situational. When opportunities for personal gain are limited and situations require deliberation, the association between grandiose narcissism and unethical behavior disappears. The paper is personality and individual differences. Grandiose narcissism is a personality trait characterized by an exaggerated sense of self-importance, a strong desire for admiration, and a belief that one is better than others. People with high grandiose narcissism tend to believe that they are special and deserve special treatment. They seek positions of recognition and recognition and positions of influence. They may show little concern for the…
