A recent study published in Nature explores how cancer cells interact with their environment. Researchers analyzed over 100 tumor samples from six different types of cancer. They aimed to uncover how these cells behave in distinct areas of the tumor, focusing on their interactions, metabolic activities, and immune responses. Challenges…

Patients can generally continue taking glucagon-like peptide-1 (GLP-1) receptor agonists before elective surgeries and gastrointestinal endoscopies, according to new guidance from five leading medical societies. These include the American Society for Metabolic and Bariatric Surgery (ASMBS), the American Society of Anesthesiologists (ASA), the American Gastroenterological Association (AGA), the International Society…

A recent observational study published in BMJ Mental Health indicates that lifetime cannabis use may lead to changes in brain structure and function in older adults. However, a genetic analysis of the same data suggests these associations may not be causal. Researchers caution that other unidentified factors could explain these…

Research published in the British Journal of Sports Medicine suggests that exercising just once or twice a week—known as the “weekend warrior” approach—can significantly reduce the risk of cognitive decline, potentially as effectively as more frequent workouts. This finding could be beneficial for busy individuals. Identifying risk factors for dementia…

Stem cells are unique in their ability to divide indefinitely, making them a focus for scientists seeking to extend human lifespans and repair damaged tissues. Pluripotent stem cells can develop into any of the body’s three main tissue types: endoderm (including intestines and lungs), mesoderm (muscle and heart), and ectoderm…

Mechanical engineers at the University of Texas at Dallas (UT Dallas) have developed a 3D-printed femur to assist doctors in preparing for surgeries that repair bones and treat bone tumors. This innovation was created in collaboration with orthopedic surgeons from UT Southwestern Medical Center. The engineers published their initial study…

The Skin Aging and Challenges 2024 conference will take place on November 5-6 at the Corinthia Palace in Malta. This event will gather top scientists and researchers to discuss the latest developments in skin health, anti-aging, and cellular rejuvenation. Key topics will include cellular senescence, mitochondrial function, the influence of…

Malaria claims over 600,000 lives each year, and with climate change, the disease’s range is expanding. Although some drugs can prevent and treat malaria, resistance to these medications is increasing. Researchers at the University of Utah Health have identified a new target for antimalarial drugs: a protein called DMT1. This…

A groundbreaking study from Arizona State University (ASU) has examined cancer prevalence among various vertebrate species, revealing significant patterns that challenge existing theories in evolutionary biology. Researchers analyzed over 16,000 necropsy records from 292 species, providing fresh perspectives on how cancer evolves in multicellular organisms. The research contests Peto’s paradox,…

A new study reveals that a genetic signature in newborns can predict neonatal sepsis before any symptoms appear. This research, conducted by teams from the University of British Columbia (UBC) and Simon Fraser University (SFU), alongside the Medical Research Council (MRC) Unit in The Gambia, could lead to earlier diagnoses,…
