New research suggests how coffee is made may be just as important as how much people drink, showing that filtered and instant coffee have very different associations with biological aging. Study: Discrepancies in the biological aging of instant and filter coffee: evidence from the UK Biobank. Image credit: Rabizo Anatolii / Shutterstock In a recent study published in npj food scienceresearchers evaluated the cross-sectional association between coffee consumption and biological aging. Aging is a complex process characterized by a gradual decline in function. Given the unprecedented rate of aging worldwide, identifying approaches to slow biological aging remains a critical challenge.…
Researchers at Dresden-Rossendorf-Helmholtzzentrum (HZDR) are testing two technologies designed to destroy per- and polyfluoroalkyl substances (PFAS), a vast group of industrial chemicals known to resist natural and conventional degradation processes. The first approach uses hydrodynamic cavitation to create and collapse small vapor bubbles in contaminated water. The second combines cold atmospheric plasma with gas dispersion. Analysis carried out by experts at the Helmholtz Center for Environmental Research (UFZ) confirmed that PFAS molecules were broken down and fluoride was released during treatment. If the technology is fully developed for commercial use, it could allow industry to treat contaminated wastewater before it…
Researchers have discovered a clue as to why immune checkpoint inhibitors – cancer treatments that release the immune “brakes” that tumors exploit to evade attack – have limited effectiveness in some brain tumors. The KAIST research team has discovered that the antitumor effects of anti-CTLA-4 therapy depend not on T cells alone, but on the response of B cells and antibodies that begin in tumor-draining lymph nodes, opening a new avenue for the treatment of intractable brain tumors. KAIST (Chairman Bae Choong-sik) announced on July 19 that a research team led by Professor Heung Gyu Lee of the School of…
Artificial intelligence is rapidly improving scientists’ ability to detect chemicals in the environment and the human body. The New Perspective article argues that the next major step is not simply to identify more chemicals, but to determine which exposures are most likely to disrupt biological systems and contribute to disease. Published in Artificial intelligence and environmentarticle describes the transition to functional chemistry exposomics, a new approach that combines high-resolution mass spectrometry, artificial intelligence, toxicology databases, and biological response data. Exposomics examines the total range of environmental exposures experienced throughout a person’s life. Modern analytical instruments can detect thousands of chemical…
A placebo-controlled trial tested whether correcting vitamin D deficiency could reduce persistent endometriosis symptoms in women already on hormone therapy, with results that cast doubt on hopes for simple add-on treatment. Study: Supplemental vitamin D supplementation in women receiving dienogest therapy for endometriosis: a randomized controlled trial. Image credit: Orawan Patarawimonchai / Shutterstock A recent randomized controlled trial has been accepted for publication in a journal. scientific reportresearchers examined vitamin D supplementation as an adjunct to dienogest (Bellogest) therapy in women with endometriosis. After the 8-week study, participants who received vitamin D had numerically lower adjusted mean scores on pain…
Talk therapy provides lasting relief from depression, and its effects last for years after treatment ends. A new large-scale meta-analysis evaluating tens of thousands of patients tracked these mental health improvements over time, mapping exactly how long people felt better. The study was published in the journal World Psychiatry. Depression is one of the most common mental illnesses worldwide. People experiencing a depressive episode often suffer from deep sadness, loss of interest in daily activities, and changes in sleep and appetite. This disorder drains a tremendous amount of physical and emotional energy and makes basic daily life seem impossible. To…
Purchasing virtual loot boxes in video games is associated with increased rates of problem gambling and human victimization among adults who already participate in traditional gambling. The study shows that spending money on these randomized digital prizes carries behavioral risks comparable to casino table games and stronger than sports betting. The results of this study were published in the journal Addictive Behaviors. Loot boxes are virtual chests or crates found in many popular video games. Players spend real-world money to open them in hopes of receiving rare digital rewards such as character costumes, weapon designs, and special abilities. The contents…
Recent research suggests that the impact of sitting on brain health largely depends on what a person is doing while resting. Published in Alzheimer’s disease and dementiaresearch shows that passive activities like watching TV are associated with signs of brain aging, while cognitively demanding tasks like working at a desk may help preserve brain structure. These findings suggest that public health guidelines may need to go beyond simply reducing total sitting time to consider the mental involvement of our daily habits. Alzheimer’s disease and related dementias pose a major challenge to public health systems worldwide. Because the effectiveness of medical…
A recent study examining how adults in love navigate the balance between solo masturbation and intimacy with a partner identified three distinct behavioral profiles. The findings suggest that a person’s motivations, attitudes toward solo sex, and the subjective pleasure they experience all determine how these two forms of intimacy coexist. The study was published in the International Journal of Sexual Health. Historically, solitary sexual behavior has been treated as a secondary indicator in relationship science. Many people believe that high rates of masturbation in a relationship indicate underlying love troubles. Researchers classify this idea as a compensatory model of sexuality.…
Researchers at the University of Hong Kong’s LKS School of Medicine (HKUMed) have developed an artificial intelligence tool that could help predict serious cardiovascular problems years before symptoms appear. The system, known as CardiOmicScore, uses information from a single blood test to estimate a person’s future risk for six major cardiovascular diseases (CVD): coronary artery disease, stroke, heart failure, atrial fibrillation, peripheral artery disease, and venous thromboembolism. The model was able to detect warning signals 15 years before clinical symptoms develop in high-risk people. The survey results are nature communications. Blood test to understand your current health condition Cardiovascular disease…
