Astronomers have long believed that the Milky Way is filled with neutron stars, the ultra-dense remnants left behind when massive stars explode. The problem is that most of these objects are invisible. New research published in astronomy and astrophysics It suggests that NASA’s upcoming Nancy Grace Roman Space Telescope may eventually be able to discover some of them. Using advanced simulations of the Milky Way and Roman’s predictions of future observations, researchers discovered that the space telescope can detect and study dozens of isolated neutron stars through a phenomenon known as gravitational microlensing. “Most neutron stars are relatively faint and…

Every night around the world, thousands of automated aerial cameras monitor flashes of light that streak the atmosphere. I’m one of the scientists studying these meteors and what they can reveal about our solar system. Popular movies and breaking news usually focus on giant asteroids that could threaten Earth. Every few months, we also hear about another large space rock passing nearby. But the much smaller particles that continually enter Earth’s atmosphere every day can tell scientists an equally interesting story. My planetary science colleagues and I analyze images from a camera network of the night sky to study debris…

Researchers have introduced a new diagnostic method that can more sensitively detect gene fusions in the most common childhood cancer, B-cell acute lymphoblastic leukemia (B-ALL), compared to other publicly available fusion detection algorithms. This tool is explained in detail in the following article: Molecular Diagnostic Journalis published by Elsevier and enables higher diagnostic yields from low-coverage, low-cost sequencing. Current treatments for B-ALL are categorized according to risk level depending on age, white blood cell count, response to treatment, central nervous system status, and genomic subtype. Pediatric B-ALL is primarily caused by chromosomal abnormalities or structural mutations, which usually result in…

A large-scale Swedish study that followed people for nearly 50 years has revealed some surprising realities about aging and physical performance. Researchers have found that physical strength, muscle strength, and muscular endurance begin to decline around age 35. But the findings also carry an encouraging message: Even if you become active later in life, you can still significantly improve your physical performance. The study was conducted at Karolinska Institutet as part of the Swedish Study on Physical Activity and Fitness (SPAF). Scientists followed hundreds of randomly selected men and women in Sweden between the ages of 16 and 63 and…

Researchers at A*STAR Genome Institute of Singapore (A*STAR GIS) have developed a new method called ‘sm-PORE-cupine’ to study individual RNA molecules and reveal how their structure influences gene regulation, a fundamental process that influences cell function in health and disease. RNA is best known for carrying genetic instructions from DNA to make proteins. But RNA does more than just function as a messenger. Like a thread that can bend, fold, and interact with other molecules, RNA can assume different shapes that influence its behavior inside the cell. These shapes can influence the efficiency of protein production, the duration of RNA…

A healthy brain may help protect thinking and memory from the early effects of Alzheimer’s disease, a new study has found. Dementia is now the leading cause of death in Australia, with Alzheimer’s disease being the most common condition, accounting for over 70% of cases. Alzheimer’s disease is a progressive brain disease that causes a gradual decline in cognitive abilities, leading to impaired memory and thinking skills. However, some people maintain high levels of cognitive function despite early signs of disease in their brains. Specifically, some older adults have brain lesions associated with Alzheimer’s disease but do not have noticeable…

Blood tests to detect potential signs of prostate cancer are likely to reduce the risk of death from prostate cancer, a new Cochrane review found. This is a change from an earlier version of the review, which found insufficient evidence that screening reduces deaths from prostate cancer. Prostate cancer is one of the most common cancers in men. Early detection through screening has long been debated, and experts disagree on whether its benefits outweigh the risks of overdiagnosis and overtreatment. Small but significant benefits The study team analyzed data from six trials involving approximately 800,000 participants in Europe and North…

As the prevalence of Parkinson’s disease rises worldwide, researchers are questioning whether targeted supplements can impact inflammation, oxidative stress, mitochondria, and the gut microbiome, but current evidence remains promising, controversial, and far from conclusive. Review: Dietary Supplements for Parkinson’s Disease: Current State of the Science. Image credit: Peterschreiber.media / Shutterstock In a recent review published in Parkinson’s disease journalour group evaluated the disease-modifying potential of nutritional supplements in Parkinson’s disease through evidence from human clinical trials. This review focused on clinical outcomes and biomarker-based evidence as surrogate measures of disease modification, rather than conclusive evidence to supplement slowing disease progression.…

The incidence of colorectal cancer is decreasing among older adults, primarily due to increased screening. But researchers are seeing an alarming change in younger people, with more cases now occurring in adults under 50, including people in their 30s. A new national study conducted in Switzerland found that while the number of diagnoses in this age group has steadily increased in recent decades, younger patients are more likely to receive a terminal diagnosis. The study was led by scientists from the University of Geneva (UNIGE) and the University Hospitals of Geneva (HUG). Published in european cancer journalThe study analyzed approximately…

A large-scale study maps sleep duration against multi-organ aging clocks and reveals why the healthiest biological aging profiles are clustered around the well-known 6-8 hour sleep window. Research: Sleep graphs of the biological aging clock in midlife and late life. Image credit: Gorodenkoff / Shutterstock In a recent study published in the journal natureIn , researchers from the MULTI consortium describe the development and potential of the Sleep Chart, a comprehensive framework developed using large-scale population data to assess the correlation between self-reported sleep duration and 23 biological aging clocks. Results of this study revealed a U-shaped relationship between sleep…
