Scientists say they may finally have uncovered why so many people struggle to give up alcohol. A new study suggests the brain physically adapts to rely on drinking as a way to ease stress and anxiety—creating a powerful cycle that makes quitting extremely difficult. Researchers at Scripps Research in California identified a specific cluster of brain cells that becomes more …

Osteoporosis is a major cause of fractures, disability and loss of independence in older adults. Smoking weakens the bones by disrupting their natural remodeling process and slowing healing. The earlier you adopt bone-healthy habits, the stronger and more resilient your skeleton will be. Staying active and independent well into the future starts with strong bones. Your skeleton does more than …

A40-PO polymersome preparation and characterization P[(OEG)10MA]20-PDPA120 and angiopep2-P[(OEG)10MA]20-PDPA120 copolymers were synthesized via atom transfer radical polymerization (ATRP) as previously reported.33 A40-POs were formulated adhering to the film-rehydration method, whereby P[(OEG)10MA]20-PDPA120 and a 1.88% molar ratio of angiopep2-P[(OEG)10MA]20-PDPA120 were dissolved in a mixture of methanol and chloroform (v/v, 3:1). The mixture was left to evaporate, allowing the organic solvent to completely …

Even though many years have passed since the start of the COVID-19 pandemic, the effects of infection with SARS-CoV-2 are not completely understood. This is especially true for Long COVID, a chronic condition that can develop after COVID-19 that causes a variety of lasting symptoms. Among the most common and debilitating of these is cognitive impairment, often referred to as …

In a groundbreaking study set to redefine our understanding of hereditary health and exercise science, researchers from Nanjing University and Nanjing Medical University have unveiled pivotal evidence that paternal exercise can profoundly influence the endurance and metabolic health of offspring. Published in Cell Metabolism, this research elucidates the critical role of sperm microRNAs as mediators of epigenetic inheritance, effectively transmitting …

Summary: Scientists have shown that neurons don’t rely solely on sugar for energy — they can also burn fat. When energy demand spikes, neurons even create their own fats by recycling parts of themselves, a process dependent on a key protein called DDHD2. In Hereditary Spastic Paraplegia 54 (HSP54), DDHD2 malfunctions, cutting off this energy source and impairing neuron function. …

Summary: Scientists have developed a powerful new imaging method that reveals how immune cells in the eye behave long before visible damage occurs in diabetic retinopathy. Using a combination of a head-fixation device, contact lenses, and a custom objective lens, researchers were able to capture live, high-resolution images of microglia activity in diabetic mice. They found that microglia—the retina’s immune …

Today the Centers for Disease Control and Prevention (CDC) said it is now applying individual-based decision-making to COVID-19 vaccination instead of making routine recommendations on use. The CDC also recommended that toddlers receive the varicella (chickenpox) vaccine as a standalone immunization rather than in combination with measles, mumps, and rubella vaccination.  “Informed consent is back,” said Acting Director of the …
