Yesterday, a friend who lives in the Bay Area told me that I should ask people about peptide “stacks.” Peptide “stacking” is where someone takes multiple peptides, presumably for greater health benefits. So, uh…do you take peptides? what is your stack? Or is this just a Bay Area bonanza? A victory for peptide supporters An advisory committee to the Food and Drug Administration recommended yesterday that compounding pharmacies be allowed to make four peptides that are very popular but little-researched drugs…

China’s Tianwen-1 spacecraft photographed the interstellar object 3I/ATLAS as it passed close to Mars. The orbiter used high-resolution cameras to capture the comet from about 30 million kilometers (18.6 million miles) away, the China National Space Administration (CNSA) said. Tianwen-1 has been in orbit around Mars for four years and eight months, making it one of the closest probes to observe interstellar objects since its discovery (May 7, 2025). Tenbun-1 reveals comet’s tail and coma The new image shows several features that support the conclusion that 3I/ATLAS is a comet. A visible tail extends behind the object, and a cloud…

Cambridge scientists have solved the mystery of why both stimulating and blocking specific ‘switches’ in the brain can help people lose weight. The discovery could help improve the effectiveness of obesity drugs. Published today is natural metabolismStudies using mice show that the answer lies in the position of the switch. Stimulating a switch in the brainstem suppresses appetite, while blocking a switch in the hypothalamus can achieve the same effect. More than 1 billion people worldwide live with obesity, which increases the risk of diseases such as diabetes, cardiovascular disease, and cancer. Weight loss can help reduce these complications, but…

Skeletal muscle is one of the first tissues to decline as we age. This decline can lead to muscle weakness, scarring, fat accumulation inside the muscles, and loss of fast-twitch muscle fibers, which are important for quick, powerful movements. A research team led by Professor Ryuichi Tatsumi of Kyushu University’s Faculty of Agriculture has identified a molecule that may help protect and even strengthen one of the body’s key muscle repair signals. The results of this investigation were announced on July 24, 2026. scientific report. This study focuses on hepatocyte growth factor (HGF), which acts like an arousal signal in…

Passively consuming endless short-form videos creates a specific type of cognitive fatigue commonly known as brain rot. A new study reveals that this digital fatigue does not directly lead to depression, but instead sets off a predictable psychological chain reaction. The findings suggest that endless scrolling drains mental energy and can lead to burnout, which in turn increases stress and anxiety, and ultimately leads to symptoms of depression. This study psychological report. In recent years, social media interactions have shifted from active communication to passive observation. The algorithm-driven platform provides users with a constant supply of highly stimulating short videos.…

A new oral antiviral drug candidate, administered before or after direct contact or airborne infection with canine distemper virus, which causes measles-like disease in ferrets, blocks transmission of the virus and reduces clinical symptoms, according to research published in the same journal. natural microbiology By researchers at Georgia State University’s Center for Translational Antiviral Research (CTAR). This study investigated whether prophylactic (just before or after exposure) administration of the recently developed clinical candidate GHP-88310 (described in Science Advances), a broad-spectrum inhibitor of viral polymerases, prevents viral transmission through close contact or airborne transmission. This result indicates that GHP-88310 efficiently blocks…

Ahead of World Drowning Prevention Day on 25 July, the World Health Organization (WHO) is launching a new technology package to help governments and communities implement seven proven measures to reduce drowning. Nearly 300,000 people drown every year around the world, and drowning remains one of the 10 leading causes of death for children aged 5-14. Many of these deaths occur in rivers, lakes, wells, household water storage containers, and swimming pools. More than 90% of drownings occur in low- and middle-income countries. Climate change is increasing the risk of drowning. Extreme weather events such as floods, storms and heat…

Researchers in Sweden are studying how the country’s mineral resources could support cleaner production of rare earth elements (REEs) and the powerful magnets made from them. As part of his research field on sustainable materials and material flows, Martin Thalberg is investigating whether Swedish mineral deposits could form the basis of a more sustainable magnet industry. Many of the materials needed for clean energy systems and advanced technologies are still produced through processes that have significant environmental costs. For example, rare earth magnets are mainly manufactured in China, where environmental regulations and industrial standards are different from those in Sweden.…

A new study by Dallas-based researchers finds that nearly all of the region’s waterways are contaminated with microplastics.A report from the Texas Center for Environmental Research and Policy urges policymakers to take steps to regulate waste that ends up in the state’s waters.”Today’s report finds that microplastics are an almost invisible constant in Texas’ waterways,” Ian Seamans, an environmental advocate with Texas City Hall, said at a press conference Thursday. “So whether you’re fishing on the Gulf Coast, swimming in the Hill Country, or paddling, for example, on White Rock Lake here in Dallas, microplastics can be present there as…

New research published in positive psychology journal It suggests that collective well-being depends more on building supportive communities than simply on individuals pursuing personal pleasure. This research provides evidence that a communitarian approach that fosters an environment in which societies care for others can be highly effective in increasing national well-being. Understanding the factors associated with improved well-being is a major goal of social science and public policy. Ewa Parikot, a postdoctoral researcher at the Macropsychology Laboratory at the Institute of Psychology of the Polish Academy of Sciences, pointed out that there can be a disconnect between individual happiness and…
