Reclaimed derogatory language is often seen as an empowering tool for marginalized groups to take back control of harmful language. But new research published in the European Journal of Social Psychology suggests that hearing recycled homophobic remarks can actually cause unintended harm. Research shows that exposure to recycled slurs desensitizes some straight listeners to standard hate speech and worsens the mood of gay people. Hate speech includes abusive or threatening words directed at individuals based on aspects of their identity, such as race or sexual orientation. Sociologists and psychologists have recognized that this type of language causes psychological distress in…

In the most aggressive forms of leukemia, blood cell factories in the bone marrow malfunction. Rather than dividing and proliferating at their normal prolific pace, producing hundreds of billions of new cells every day, some progenitor cells stall at an immature stage. they never end. They are never what they should be. Since these are progenitor cells, they don’t actually have any function, they just expand or collapse the bone marrow. ” Raquel Espin-Palazon, Associate Professor of Genetics, Developmental and Cell Biology, Iowa State University A new discovery by a research team led by Espin Parazon identifies two essential components…

Improving diets is one of the world’s biggest public health and environmental challenges. More than 2.5 billion adults are currently overweight or obese, 88% of countries with available data face a severe burden of two or more types of malnutrition, and food systems account for a quarter to a third of global greenhouse gas emissions. Published in natural foodthis study introduces MATILDA (Micro-Macro Assessment Tool for Identifying Low-Impact Dietary Behaviors), a global database that combines individual dietary surveys with country-level food supply chain and population data. Covering 165 countries, it provides a globally harmonized picture of how the nutritional quality…

Chimeric antigen receptor (CAR)-T cell therapy, which reprograms an individual’s immune cells to seek out and destroy specific cancer cells, has revolutionized the treatment of blood cancers such as lymphoma. However, for some patients, this treatment can cause serious side effects. A new study led by researchers at the Massachusetts General Brigham Cancer Institute, the Broad Institute of Massachusetts Institute of Technology and Harvard University, and the Dana-Farber Cancer Institute shows that a patient’s genetic genetic makeup can influence whether they benefit from CAR T-cell therapy or experience toxicity from the treatment. The result is scientific immunology. “These findings have…

The abnormal behavior of cells in pre-eclamptic mothers and their babies could represent a new therapeutic target for the condition, new UCL-led research has found. Preeclampsia is a leading cause of maternal and fetal death, affecting 2-4% of pregnancies worldwide. This disease causes the mother’s blood pressure to become too high, which affects blood flow to the baby and can cause symptoms such as swelling, headaches, blurred vision, and pain under the ribs. If left untreated, it can harm the mother’s health, slow the baby’s growth, and in severe cases can be life-threatening. However, there is currently no cure. Now,…

For more than a century, scientists have been trying to reconstruct human evolution using a variety of evidence, including fossils, genetic variation between populations, and ancient DNA. Building on these approaches, researchers are increasingly using large population biobanks to investigate how natural selection continues to shape the genomes of living populations. In the new study, researchers analyzed genomic data from more than 72,000 Han Taiwanese Taiwanese Biobank participants by comparing allele frequencies across adult age groups. This analytical framework allowed us to identify genomic hallmarks of ongoing natural selection and reveal disease-associated genetic variations that might otherwise go undetected. Published…

For millions of Americans, where you live is quietly becoming one of the biggest predictors of how long you will live. In rural areas across the country, healthcare systems are undergoing rapid and irreversible changes. Since 2005, more than 200 local hospitals have closed, and many more are at risk of closure. The White House Rural Health Transformation Program, led by Dr. Mehmet Oz and the Centers for Medicare and Medicaid Services (CMS), has warned that the country is entering an era in which life expectancy is predicted by ZIP code. The health disparities faced by rural Americans are well…

Researchers have developed a wearable patch that can detect hazards in the environment, such as dangerous gases or heavy metals in water, and notify the wearer by vibrating the skin. The researchers also extended their work to create “e-skins” for robotic devices that allow robots to detect and avoid hazards in the environment. We already have sensors that can detect environmental hazards and send notifications to your phone, but we wanted to improve on that. This work had two goals. First, they wanted to miniaturize the sensor and incorporate it into a wearable patch to identify potential risks to…

WASHINGTON — A Food and Drug Administration advisory committee recommended Friday that compounding pharmacies be allowed to make the peptide epitalon, but narrowly voted against recommending that they make emideltide. The vote follows the committee’s decision Thursday to recommend allowing pharmacies to manufacture four other peptides, bringing Health Secretary Robert F. Kennedy Jr. one step closer to his mission to make these unapproved compounds more accessible to Americans. Peptides, short-chain amino acids, are becoming increasingly popular in the United States with support from social media influencers. The two-day conference highlighted broader tensions between the “Make America Back to Health” movement…

Skeletal muscle often begins to deteriorate relatively early in the aging process. Over time, this can cause muscle weakness, increased scarring, accumulation of fat within muscle tissue, and a decrease in fast-twitch muscle fibers that support quick, powerful movements. Researchers led by Professor Ryuichi Tatsumi of Kyushu University’s Faculty of Agriculture have identified a molecule that can protect and enhance key signals involved in muscle repair. The results will be announced on July 24, 2026. scientific report. How the body activates muscle repair The study focuses on hepatocyte growth factor (HGF), a protein that helps initiate skeletal muscle repair. Under…
