The advent of mRNA vaccines against SARS-CoV-2 in 2020 changed the course of the COVID-19 pandemic. This Nobel Prize-winning technology is now being applied in the fight against cancer, with mRNA vaccines being tested in clinical trials against melanoma, small cell lung cancer and bladder cancer, among others, opening the door to new ways to prevent and treat the disease. Scientists hypothesized that mRNA vaccination requires one specific immune cell subtype to activate the immune system. But researchers at Washington University School of Medicine in St. Louis have shown in a new study in mice that even in the absence…
New research led by the University of Warwick shows that forests were already growing across Doggerland, now submerged under the North Sea, much earlier than scientists previously thought. The discovery suggests that this lost landscape may have served as a welcome haven for plants, animals, and perhaps humans, long before forests became commonplace in Britain and across northern Europe. This research Proceedings of the National Academy of Sciences (PNAS)used deposited ancient DNA to discover evidence of temperate trees such as oak, elm and hazel that are more than 16,000 years old. The researchers also detected DNA from a genus of…
A study in Brazil found that people with good cardiorespiratory fitness tended to have lower levels of trait anxiety. They also tended to be more resilient in situations of emotional stress. The paper was published in Acta Psychologica. Cardiorespiratory fitness is the ability of the heart, blood vessels, lungs, and muscles to efficiently supply and use oxygen during sustained physical activity. This reflects how well your body can perform activities such as walking, running, cycling, and swimming for long periods of time without becoming unduly fatigued. People with good cardiorespiratory fitness can usually exercise for longer periods of time and…
○last month’s versionoil prices bounced around like a lie detector. The joint U.S.-Israeli attack on Iran, which began in February, triggered the biggest one-month price increase in oil history. The price of Brent crude oil rose and fell sharply each time a war broke out. Important points Due to the Iran war, oil price fluctuations have recently intensified around the world. Global financial institutions have consistently identified rising oil prices as the main driver of inflation. Risks of dependence on other countries’ oil have led some countries to expand their use of renewable energy Just as Russian President Vladimir Putin…
Vince Lahey of Carefree, Arizona, embraces chatbots. From big tech products to “shady” products, they offer “someone with whom you can share more secrets than a therapist.” He particularly likes the app for feedback and support, but it can also cause him to get reprimanded and get into fights with his ex-wife. “It made me want to share more,” Lahey said. “I don’t care about their perception of me.” There are many people like Lahey. Demand for mental health care is increasing. The number of self-reported days with poor mental health has increased by 25% since the 1990s, a study…
Millions of people applying for Medicaid in the coming years will need to prove they have worked, attended school or volunteered for at least a month to obtain or maintain health insurance through the government program. But Republican lawmakers in some states don’t think the new rules, part of the GOP’s One Big Beautiful Bill Act, signed by President Donald Trump last July, go far enough. Indiana is at the forefront of this movement, enacting a new law that requires applicants to prove they have worked or participated in similar activities for three consecutive months in order to receive benefits.…
Cancer risk increases with age and is often more aggressive and difficult to treat in older people. However, less than 10% of mouse studies use older animals, and most rely on mice roughly equivalent to humans in their early 20s. This discrepancy is one potential reason why many anticancer drugs that have shown promise in preclinical models continue to fail in human trials.New research from Fox Chase Cancer Center presented at the American Association for Cancer Research annual meeting suggests that melanoma behaves differently with age. The data showed that cancer spread was lowest in young mice, peaked in middle-aged…
The FDA should strengthen the evidence needed to approve drugs under the accelerated pathway and increase transparency around regulatory decisions, according to a report (PDF) from a prominent industry and government watchdog. In the same report, the Institute for Clinical and Economic Review (ICER) also recommends that advisory committees review medicines scheduled for accelerated approval and that pathways more clearly explain the benefits and risks associated with the use of approved medicines within that scope. “The goal of the accelerated approval pathway has always been to give patients access to innovative treatments faster,” Sara Emond, CEO of ICER, said in…
The number of babies born in the United States fell again last year. There will be 3.6 million births in 2025, a 1% decrease from 2024, according to new data from the Centers for Disease Control and Prevention. The birth rate has fallen to 53.1 births per 1,000 women aged 15 to 44, a 23% decrease since 2007. The Trump administration has said it wants to reverse this trend. President Donald Trump has called for a “new baby boom,” and aides are seeking proposals from outside advocates and policy groups on everything from maternity benefits to expanded birth planning. The…
Developmental dysplasia of the hip (DDH) is a polygenetic disease that increases the risk of hip osteoarthritis. A new multi-ethnic study has found that variations in three genes related to collagen and bone formation are associated with DDH. Other downstream genes are also associated with hip osteoarthritis. These findings point to possible mechanisms behind DDH and potential targets for new treatments for hip osteoarthritis. Developmental dysplasia of the hip (DDH) is a disorder of the hip joint that affects posture and movement. Symptoms of DDH can appear as early as a few weeks after birth and can range in severity…
