Consider two seemingly unrelated medical puzzles. First: Every day, our bodies generate hundreds of billions of new cells, many of which mutate. If cancer arises from cell mutations, why don’t we all get the disease all the time?Second, severe autoimmune diseases such as lupus and multiple sclerosis often develop without warning. No one knows what triggers them. A new study from Cold Spring Harbor Laboratory (CSHL) shows that naturesuggesting that the two puzzles may be directly connected. This research has revealed that our immune systems are pre-equipped with antibodies that fight tumors and attack the brain. ”Patients with autoimmune diseases…

You can contact Helen on Signal at hbranswell.01.Staff at the Centers for Disease Control and Prevention met on Wednesday, with many expecting an announcement by the Trump administration of the selection of a new leader for the beleaguered agency. But instead, acting director Jay Bhattacharyya said a permanent director is likely to be named by Thursday. A transcript of the hour-plus all-hands meeting obtained by STAT revealed that staff members asked Bhattacharyya tough questions. Mr. Bhattacharya scored…

A new report shows that Iowa has higher rates of more than a dozen types of cancer associated with pesticides and pollutants than other regions, and researchers say pesticide exposure alone can rival the risks of smoking. Iowa has the second highest cancer rate in the nation. Only 1 of 3 states with cancer on the riseaccording to the National Institutes of Health. For many types of cancer, the state’s numbers are well below the national average. For example, the prostate cancer incidence rate in Iowa is 129 per 100,000 people, while the U.S. average is 116 per 100,000. The…

Over the past two decades, psychological distress has increased among teenagers, especially adolescent girls, around the world. Recent research published in Journal of Child Psychology and Psychiatry Paradoxically, countries with higher levels of gender equality are found to have wider disparities in mental health between boys and girls. Researchers link this widening gap to the double burden of increased academic pressure and expectations placed on young women. Adolescence is a sensitive period of brain development and social growth. Mental health problems that begin during these formative years often continue into adulthood. Around the world, mental health indicators among teenagers have…

The heart needs oxygen. A heart attack is the most dramatic example of this starvation, when the coronary arteries become clogged and starve the muscles of oxygen they need to keep beating. Less sudden heart failure means that the heart is unable to pump enough blood around the body due to a lag in oxygen consumption levels. Determining how much oxygen the heart is using or not using can help detect heart failure. This is important in planning treatment in the early stages of heart failure, which affects one in four Americans during their lifetime. Other ways to reach a…

Many patients with an aggressive blood cancer called diffuse large B-cell lymphoma are cured with the current gold standard treatment: a combination of antibodies designed to wipe out cancerous B cells and four chemotherapy drugs. However, this treatment fails in about three out of 10 patients, and the powerful chemotherapy can cause heart damage, a significant risk for older patients, who make up the majority of those diagnosed. Despite these risks, clinicians are often reluctant to try new treatment regimens that may be less toxic because there is no reliable way to predict whether a patient’s cancer will respond. A…

Small cell lung cancer (SCLC) is one of the most aggressive types of lung cancer, with a 5-year survival rate of only 5%. People often respond well to chemotherapy initially, but the effects are usually short-lived. Most patients experience a relapse, followed by rapid disease progression. Because of this pattern, understanding the biology behind SCLC is important to prolong treatment efficacy, prevent recurrence, and improve long-term outcomes. A research team led by Professor Silvia von Karstedt (Translational Genomics, CECAD Aging Research Cluster of Excellence, Cologne Center for Molecular Medicine — CMMC) has identified a previously unknown process that may explain…

Most people don’t think twice about the sponge next to their sink, but new research suggests it’s responsible for more pollution than expected.Scientists have found that daily dishwashing can release tiny plastic particles from sponges, with some types releasing far more plastic particles than others. At the same time, the study points to a larger factor in the environmental impact: the amount of water used during washing. Taken together, these findings shift the focus from just what we use to how we use it.Worn sponge in sinkAcross the volunteer kitchens, three common sponge designs returned from daily use,…

New research published in Social science and medicine Evidence shows that access to high-speed rail networks significantly improves cognitive health in middle-aged and older adults. The findings suggest that large-scale transportation infrastructure can act as an unexpected tool for public health, providing psychological well-being benefits alongside pure economic efficiency. By reducing depression, reducing air pollution, and increasing personal incomes, high-speed rail appears to offer a unique path to healthier aging. As the global population continues to age, cognitive decline has become a major public health issue. Declining mental capacity not only affects a person’s daily life but also imposes a…

The macroscopic star γ Cas in the constellation Cassiopeia has confounded astronomers for decades. It produces X-rays that are much more powerful and hot than what scientists would expect from a typical massive star. New observations using the Resolve instrument aboard Japan’s XRISM space telescope now link these emissions to white dwarfs orbiting the star. The discovery also confirms a long-predicted type of binary star system that has not been clearly identified. The results of the study, led by researchers at the University of Liège, astronomy and astrophysics. What is so rare about gamma casiopeias? Gamma Cassiopeiae was the first…
