Repeated weight gain and loss can not only derail diets but also accelerate muscle loss in middle-aged people, a new University of California, San Francisco study finds, as weight-loss drugs revolutionize obesity treatment. In a study published on July 21, Radiologyresearchers found that even though both groups finished the study with about the same total body weight as they started, those whose weight fluctuated repeatedly lost significantly more thigh muscle over four years than those whose weight remained relatively stable. “When people’s weight changed cyclically, they lost a lot of muscle along with fat, and the muscle never came back,”…

The Pulmonary Embolism Reporting and Data System (PE-RADSTM) framework for diagnosing and classifying acute pulmonary embolism using CT and magnetic resonance (MR) angiography was announced today. RadiologyJournal of the Radiological Society of North America (RSNA). Developed by the American College of Radiology (ACR) in collaboration with representatives from six other major medical groups, PE-RADS aims to streamline communication and patient care for potentially life-threatening diseases. Timely and accurate assessment of acute pulmonary embolism is essential. Blood vessels in the lungs can suddenly become blocked, reducing blood flow and putting strain on the heart, which can be fatal if untreated. Common…

City of Hope®, one of the nation’s largest and most advanced cancer research and treatment institutions, home to a national medical center ranked among the nation’s top cancer centers by U.S. News & World Report, has launched an innovative Phase 2 clinical trial aimed at mapping how tumors change when they begin to resist immunotherapy, a treatment that improves the immune system’s ability to fight disease. This study will focus on advanced non-small cell lung cancer (NSCLC), the most common type of lung cancer, accounting for 87% of cases. The six-year IMMUNO-BIOMAP trial, which aims to enroll 535 patients with…

A study examining the association between emotional attachment, mentalizing ability, and hypersexual behavior found that among people with high sexual desire, attachment anxiety and avoidance (i.e., attachment anxiety) were associated with hypersexual behavior. People with higher mentalizing abilities were less likely to engage in excessive sexual behavior. The paper was published in. Journal of Sex Research. Mentalization is the ability to understand one’s own and others’ actions in terms of their underlying thoughts, feelings, intentions, and desires. This ability develops through early attachment relationships in which caregivers help children recognize, label, and regulate their internal states. However, because caregivers tend…

Seizures travel through the brain within seconds, making it difficult to capture them in detail. To overcome this challenge, researchers developed a new high-resolution light-sheet imaging system that is fast enough to image seizure propagation in 3D within the brain of larval zebrafish. We have developed a light-sheet microscope that corrects for aberrations, a flaw in the way microscopes form images, in real time and enables rapid volumetric imaging. While most imaging of seizure events in zebrafish captures only 2D images, our system allows for 3D high-resolution imaging in larger volumes than previously possible. ” Peter Kner, Research…

Scientists have developed a predictive technique that can reveal the strength of the sun’s next cycle as much as seven years before it reaches its maximum. The method focuses on the number of sunspots present during the newly identified “switch-off” phase of the solar cycle. At this point, the Sun’s harshest space weather appears to end abruptly. Researchers have already used this approach to make early estimates of solar cycle 26. Early predictions suggest that Period 26 could be moderate, with around 100 to 120 sunspots. That means it could be comparable to, or even weaker than, the current solar…

Astronomers have reached a major turning point in the search for extraterrestrial life by detecting an atmosphere around a rocky, Earth-like planet located in the habitable zone of another star. The discovery provides the strongest evidence yet that planets with broadly Earth-like temperatures and rock compositions exist outside the solar system and may also harbor conditions that could support life. “Atmospheres are essential for planets to support life as we know it,” said lead author Colin Cherubim, who recently completed his Ph.D. in Earth and Planetary Sciences from Harvard University. “This is the first time that we have discovered the…

The world’s largest sand island, Kgari is famous for its impressive freshwater lake. But new research from the University of Adelaide suggests that even the island’s largest and deepest lakes could disappear under certain climate conditions. By examining ancient layers of lake sediment, researchers found evidence that some lakes dried up about 7,500 years ago. This period, known as the Middle Holocene, arrived several thousand years after the last ice age and was generally wetter than today. Dry ancient lake in a humid climate “Our study shows that some of Kgari’s deepest lakes dried up around 7,500 years ago, long…

Karoo Health, a values-based cardiology company, has secured $16.2 million in a Series A funding round to strengthen its partnerships with health plans and cardiac practices. Allumia Ventures and 7wire Ventures co-led the round, with participation from First Trust Capital Partners, LLC, SpringRock Ventures, Hyde Park Angels (HPA) and other major investors. According to the company, Karoo Health has developed an artificial intelligence-native cardiovascular platform designed to connect payers, healthcare providers, and patients through integrated data and workflow layers that support early risk detection and improved overall cardiovascular disease outcomes. “The challenge in cardiovascular care today is not a lack…

Ancient DNA is revealing new details about the people who lived at Shimao, one of China’s most important Late Neolithic settlements. The survey results are naturerevealing the origins, family relationships, and social organization of populations. They also identified genetic links to communities further south and provided evidence that mass burials associated with human sacrifice at the site included primarily men. The project was led by Professor Qiaomei Fu from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP), Chinese Academy of Sciences. Researchers from the Shaanxi Academy of Archeology and several other institutions also contributed to the study. Over a period…
