T cells are the immune system’s elite fighting force, seeking out and destroying diseased cells. However, in long-term operations against chronic diseases such as viral infections and cancer, the body requires a steady supply of these killing squads. How and where these murder squads are generated is a mystery. This prompted a team of scientists from Weill Cornell Medicine and Memorial Sloan Kettering Cancer Center (MSK) to dig deeper. They discovered that a small subset of T cells called stem T cells are responsible for generating and continually recruiting new T cells in chronic diseases. Importantly, these rare stem T…

Scientists at the University of California, San Diego have uncovered how genetic mutations cause a rare group of inherited neuromuscular disorders and identified promising new strategies to correct them, including potential new uses for existing antidepressants. This study naturefor the first time revealed the structural mechanisms underlying congenital myasthenic syndromes (CMS), a family of genetic disorders that weaken communication between nerves and muscles. The findings provide a roadmap for developing precision medicine tailored to each patient’s specific genetic mutations. CMS affects children from birth or early childhood and can cause severe muscle weakness, difficulty walking, breathing problems and, in the…

Researchers from VIB and the University of Leuven, in collaboration with international partners, have revealed how fatty liver disease drives the most aggressive form of metastatic colorectal cancer. Research results published in major journals natureIn addition to explaining why some patients face dramatically poor outcomes, we highlight that metabolic conditions such as fatty liver disease can directly influence cancer progression, paving the way for more precise treatments tailored to a patient’s metabolic health. Colorectal cancer (CRC) remains one of the leading causes of cancer-related deaths worldwide, accounting for nearly 1 in 10 people diagnosed with cancer, and is now the…

A team led by researchers from the German Cancer Research Center (DKFZ) and the HI-STEM Stem Cell Institute has discovered a promising new approach to treating advanced colorectal cancer. This study natureidentifying key markers for particularly aggressive and treatment-resistant colorectal cancer cells. At the same time, researchers used mini-tumours and mouse models to demonstrate that already approved drugs targeting this marker can specifically attack cells that initiate metastases, and that their efficacy is significantly increased when combined with standard treatments. Colorectal cancer is one of the leading causes of cancer-related deaths worldwide. The situation is particularly critical in the case…

Two studies on cultural closeness found that people in culturally close U.S. states were more likely to support racial stereotypes and right-wing authoritarianism, and had a higher desire for certainty. This study also reported associations between cultural closeness and personality traits such as openness, extraversion, and conscientiousness, but these relationships depended on how cultural closeness was assessed. The paper is Personality and Social Psychology Bulletin. Cultural closeness refers to the degree to which a society has strong social norms and expects people to adhere to them. Rigid cultures typically have strict rules about acceptable behavior and relatively little tolerance for…

Evernorth announces a new specialty pharmacy program powered by AI to support a better experience for patients with complex conditions. The program, called Pharmacy Forward, aims to leverage technology to drive more coordinated, connected care and provide personalized support in real-time. Evernorth will begin the program with Acredo specialty pharmacy customers and will invest $100 million in the project through 2028. The goal is to speed prescription processing and service response while allowing medical teams to spend more time on clinical and patient care, the company said in a statement. “Patients navigating complex health conditions often require comprehensive expert support…

A new clinical trial led by researchers at University College London (UCL) has found that 10 weeks of cognitive rehabilitation can help people with long-term coronavirus symptoms, such as brain fog, achieve their goals of returning to work or hobbies. This is the first treatment to have a clinically meaningful and durable effect on the cognitive impairment associated with long-term COVID-19 infection. The treatment, delivered over an hour-long one-on-one video call, saw therapists help people with long-term COVID-19 to develop strategies to achieve their rehabilitation goals, with results that lasted at least six months for most participants, according to the…

With severe diseases of the aortic valve, choosing a new heart valve is especially difficult for young women who want to become pregnant. A new Swedish registry study by Karolinska Institutet shows that biological aortic valves lead to better pregnancy and birth outcomes, even though they often require additional surgery than mechanical valves. The study was published in the Journal of the American College of Cardiology (JACC).In cases of severe aortic valve disease, even young women may need surgery to replace the valve. There are two main options. Although mechanical valves are very durable, they require lifelong treatment with blood-thinning…

The National Park Service will set off more than 850,000 fireworks into the skies over Washington on Saturday to commemorate the nation’s 250th anniversary, illuminating the nation’s capital with a blast of patriotic light. Then the fallout occurs. Scientists have well-documented the soot and heavy metal pollution that can spike dramatically after fireworks displays, and experts say the world record-setting number of fireworks scheduled for July 4 means a similarly large pollution spike. According to the National Park Service, only 7,000 fireworks were set off in Washington last year. Multiplying this by 120 also means that water pollutants such as…

Belief in karma leads people to justify the misfortunes of others, but it also makes them more willing to donate money to those in need. New research shows that thinking about karmic rewards primarily increases generosity when the recipient of help is seen as a blameless victim of the situation. These findings were published in the journal Personality and Social Psychology Bulletin. Karma is a concept of cause and effect originating from Asian religious traditions. It suggests that cosmic forces ensure that good behavior is ultimately rewarded and bad behavior punished. This principle exists as a fundamental belief in Hinduism…
