New research suggests that native bee species that nest inside plant stems may face the greatest immediate threat from rising temperatures linked to climate change. In contrast, bees that nest underground appear to be better equipped to avoid dangerous heat. This study nature communicationsinvestigated the heat tolerance of 95 native bee species found across mainland eastern Australia, from the tropical north to the cool south. A team of researchers from Macquarie University, the University of Sydney, La Trobe University, Flinders University, the University of Wollongong, the University of Adelaide and the University of Queensland investigated how heat tolerance has evolved…

Most Americans hate data centers. Recent polls have found that Democrats and Republicans alike oppose the installation in their neighborhoods, and hundreds of communities across the country are protesting, citing concerns about noise, water pollution and utility costs. Many politicians have spent years courting technology companies and now vow to protect voters from their advances. In just the last month, policymakers in New York, Texas, Pennsylvania and Utah have proposed restrictions on facilities. For AI startups and other companies competing to secure more computing power, the question seems not to be which projects will face opposition and which ones will…

Daniel is responsible for the interface between the healthcare industry and the federal government. He reports on corporate influence in government, the health impacts of federal policy, and health care policy. Sensitive information can be sent via Signal (danielp.100).WASHINGTON — Senate Democrats have launched an investigation into the Trump administration’s review of federal vaccine policy and are asking the agency to turn over records by next week. In a letter to Health Secretary Robert F. Kennedy Jr. seen by STAT, Democrats Ron Wyden of Oregon and Maggie Hassan of New Hampshire on the Senate Finance Committee criticized changes Kennedy made…

A large study suggests that some common food preservatives may be putting your heart health at risk. A large study of 112,395 people tracked their diets in incredible detail, including the specific food additives participants ingested. Researchers have identified eight commonly used food preservatives that are associated with increased risk of high blood pressure and cardiovascular disease. The strongest association was seen in people who ingested the highest amounts of preservatives, suggesting that greater exposure may pose greater health risks.People who regularly consume foods containing common preservatives may be at increased risk of developing high blood pressure and cardiovascular disease,…

Mayo Clinic researchers have discovered a previously unknown mechanism by which the kidneys help maintain water balance in the body. This discovery could ultimately lead to better treatments for polycystic kidney disease (PKD) and other conditions. The study, led by Mayo Clinic nephrologist Dr. Fuad Chebib, clinical research journal. Scientists have long believed that the body’s ability to concentrate urine and avoid dehydration depends primarily on the hormone vasopressin. New research reveals that the kidneys also have another pathway to regulate water that functions independently of vasopressin. “The kidney’s ability to regulate water is one of the most fundamental processes…

Once viewed primarily as a fertility disorder, PCOS is being reframed as a systemic endocrine and metabolic disease, opening the door to earlier diagnosis, more accurate risk profiling, and more personalized care. Pathophysiology of PCOS/PMOS. PCOS/PMOS is a complex syndrome involving multiple feedback loops in the anterior pituitary gland, liver, pancreas, and ovaries, ultimately leading to a hyperandrogenic state. In the pituitary gland, LH is released in greater amounts than FSH and stimulates the membranous cells of the ovary to increase androgen production. Androgens then stimulate the pituitary gland to release LH and FSH. Increased androgens also act on the…

From gait speed and DNA methylation to AI scans and clinical texts, a major review maps how scientists measure aging and why the field needs stronger evidence before these tools can guide patient care. Distinction between CA and BA and progression of the epigenetic clock over multiple generations. (a) Chronological age reflects a fixed time scale, whereas biological age reflects cellular and physiological decline. (B) First generation clocks (Horvath, Hannum, etc.) were trained to predict chronological age. Second generation clocks (PhenoAge, GrimAge, etc.) focus on phenotypic health and mortality risk. Third generation clocks (such as DunedinPACE) measure the current rate…

A global modeling study has warned that increased aircraft NOx emissions could sharply increase the health burden on the aviation industry, despite the industry’s focus on carbon-neutral flight. Research: Impact of increasing aircraft emissions on global air quality and human health. Image credit: ChatGPT / OpenAI Researchers quantified the current and future global health impacts of aviation-related air pollution by modeling aircraft emissions under multiple scenarios and estimating the impact on mortality. This research was published as a “paper” in a journal Communication Earth and Environment The authors are Flávio DA Quadros, Rick Nelen, Mirjam Snellen, and Irene C. Dedoussi,…

A new review maps how microbial signals from the gut disrupt appetite control, insulin sensitivity, inflammation and pancreatic function, suggesting a more targeted future in the treatment of metabolic diseases. Article: The microbiota-gut-brain axis: new mechanisms and therapeutic frontiers in obesity and type 2 diabetes. Image credit: Kateryna Kon / Shutterstock Review research paper. Available as a journal press article npj biofilm and microbiome, describe how gut microbial messengers contribute to the pathophysiology of obesity and type 2 diabetes via the microbiota-gut-brain axis. background The microbiota-gut-brain axis is a bidirectional communication network between the gut microbiota and the central nervous…

A study led by the University of California, Riverside that included more than 3,200 emergency department (ED) patients across the United States found that although influenza vaccination awareness is widespread, most adults presenting to the emergency department are not up to date on their annual influenza vaccination. The survey results are Emergency Medicine Journalsuggesting that EDs may play an important role in increasing vaccination rates, especially among medically underserved populations. Led by Dr. Robert Rodriguez, professor of medicine at UCR, researchers surveyed 3,285 adult patients at 10 emergency departments in eight U.S. cities from April to December 2024. Almost all…
