Researchers at the Salk Institute for Biological Studies, UNC Lineberger Comprehensive Cancer Center, and University of California, San Diego have identified a new genetic mechanism that influences how key immune cells decide their fate. These cells, known as CD8 “killer” T cells, either develop into durable defense cells that provide lasting protection or fall into a debilitating state known as fatigue. The study found that switching off just two genes could restore the tumor-attacking ability of exhausted T cells. This study natureprovides a framework that may allow scientists to intentionally program T cells to maintain both long-term immune memory and…

Researchers at Memorial Sloan Kettering Cancer Center (MSK) have made an important discovery about how genetic mutations in breast cancer patients interact to promote resistance to certain drugs called CDK4/6 inhibitors. This discovery is naturepropose a new strategy to predict and prevent resistance to specific therapies based on a tumor’s genetic profile. This represents a major advance in understanding and predicting cancer behavior in response to treatment. ” Pedram Razavi, MD, Physician Scientist, Memorial Sloan Kettering Cancer Center Razavi co-led the study with physician and scientist Sarat Chandarlapati, MD. The study’s lead author was Dr. Anton Safonov, a…

Humans and animals share a remarkable ability to sense when others are suffering and respond with comforting actions. However, the motivation for doing so and why it sometimes fails is poorly understood. UCLA Health researchers seek to better understand this in a new study published in Nature, uncovering brain circuits in mice that link two seemingly disparate social behaviors: caring for vulnerable offspring and comforting a suffering peer. The discovery provides the first direct neurological evidence for the long-standing evolutionary hypothesis that the biological urge to help others may have its origins in ancient mechanisms of parental care. why is…

Diabetic macrovascular complications are the main cause of death and disability in diabetic patients, and vascular calcification is one of its important pathological mechanisms. Calcification of atherosclerotic plaques can cause vessel wall stiffness and decreased compliance, which can induce atherosclerotic plaque rupture, thereby increasing the risk of acute cardiovascular events. Compared with non-diabetic patients, diabetic patients have atherosclerotic plaques in their coronary arteries, with larger necrotic cores and extensive calcification. Vascular calcification is an active process that involves osteoblast differentiation and vascular smooth muscle cell (VSMC) mineralization. However, the molecular mechanisms underlying vascular calcification in diabetic atherosclerotic plaques are not…

A September 2025 White House briefing in which women expressed concerns about acetaminophen use during pregnancy and touted the drug leucovorin as a potential autism treatment led to a radical change in how doctors across the country prescribe these drugs, according to a new study. The study shows that after the September 22, 2025 briefing, orders for acetaminophen for pregnant women in the emergency room decreased significantly, while prescriptions for leucovorin for children increased dramatically. The study was authored by researchers from the Brown University School of Public Health and Brigham General, Massachusetts. Lancet. According to the authors, the changes…

Scientists have discovered that electrons can be propelled through solar materials at nearly the fastest speeds allowed by nature. This is a result that challenges long-accepted ideas about how solar energy systems work. The discovery could open new avenues for designing technologies that more efficiently capture sunlight and convert it into electricity. Researchers at the University of Cambridge observed the separation of charges during a single molecular vibration in a laboratory experiment that tracked an event lasting just 18 femtoseconds (less than one quintillionth of a second). “We intentionally designed a system that, according to conventional theory, should not transfer…

Specialist palliative care can save up to £8,000 per person and improve quality of life. The new study, published by researchers from the National Institute for Health Research’s (NIHR) Palliative and End-of-Life Care Policy Research Unit at King’s College London, Hull York Medical School, the University of Hull and the University of Leeds, looked at two methods of care for people living at home and those in acute hospital settings. In addition to significantly reducing overall per capita care costs, specialist palliative care provided at home or in hospital has been found to be associated with improved quality of life…

A new technology has been developed to suppress immune rejection, the biggest challenge in organ transplantation, without causing systemic side effects. A research team from Pohang University of Science and Technology (POSTECH) and Ewha Womans University has developed an “immune shield” technology that uses mussel-derived adhesive proteins to spray immunosuppressants directly onto organ surfaces. These research results have recently controlled release journalan international journal in the field of pharmacology and drug delivery. Organ transplantation is the most effective treatment for restoring organs damaged by accident or disease. However, there is a severe global shortage of transplantable organs. Although xenotransplantation (transplanting…

Researchers at Cornell University have used high-resolution 3D imaging to identify atomic-scale defects in computer chips for the first time. These small defects can interfere with chip performance and are a major concern for modern electronics. This new imaging technology was developed through collaboration with Taiwan Semiconductor Manufacturing Company (TSMC) and Advanced Semiconductor Materials (ASM). The discovery could have implications for many areas of technology, as computer chips power devices ranging from smartphones and cars to AI data centers and quantum computers. The results of this survey were announced on February 23rd. nature communications. PhD student Sheikh Karapetian served as…

As the brain develops, neurons grow long extensions known as axons. These structures connect different areas of the brain and send signals both within the brain and throughout the body. To establish these connections, axons must travel along very specific routes within brain tissue. Their journey depends not only on the physical properties of their surrounding environment, but also on chemical signals. Until now, scientists did not fully understand how these two types of guidance work together. An international team of researchers has discovered that the stiffness of brain tissue can control the production of key signaling molecules. The survey…
