New research reveals that metformin’s power may start in the brain, reshaping our understanding of blood sugar control and healthy aging. buff.ly/FpkUdyU

There has always been a dream that there could be a pill to replace exercise. New research suggests a molecule called betaine, naturally produced by the kidneys, may do just that. buff.ly/UBfcVjF

Loss of appetite, whether from restrictive eating disorders in childhood or illness-driven wasting in adulthood, can trigger lasting, structural changes in the brain. buff.ly/Y4c4kbI

A fundamental discovery is overturning decades of molecular biology. Thousands of previously “invisible” microproteins—tiny chains of fewer than 100 amino acids—can profoundly change human biology when mutated. buff.ly/19EBLaA

Anyone who has shivered through winter knows how powerfully the body responds to cold. But what if simply remembering the cold could trigger the same effect? buff.ly/SjLxzTa

There are moments when the world seems to fall away: the hush of a forest after rain, the sweep of a symphony, the infinite sprawl of stars overhead. Neuroscience, at last, is beginning to map what happens in the brain. buff.ly/c3GZ6Wp

Imagine hearing a sound that once signaled danger. Your body tenses. This tension is the legacy of how fear learning shapes the brain. The process of extinction is the attempt to undo that learning, replacing it with new knowledge. buff.ly/0iDYvb0

Depression affects millions worldwide, yet its root cause has long remained elusive. Behind its lived experience lies a biological mystery: Why does the brain, an organ built to adapt and survive, sometimes disrupt its own careful harmony? buff.ly/Tve0V1U

Aging and inflammation are deeply interconnected processes shaping much of the human experience. New scientific findings reveal that healthy aging may be possible by managing chronic inflammation—a phenomenon now called “inflammaging.” buff.ly/CsbVXsv

In less than a decade, bispecific antibodies have become frontline therapeutics. With more than 2,000 clinical trials in oncology underway and U.S. cancer drug spending projected to hit $440 billion by 2029, the race is on to harness these molecules. buff.ly/kijzjtu

For centuries, we’ve thought of these changes as part of the "genetic lottery," something we can't control. Now, a significant study published in Nature Communications provides some of the clearest answers yet. buff.ly/Ea3O6Ux

Emerging research shows that when one partner in a couple has a psychiatric disorder, the risk of similar conditions rises sharply for the other partner and their children. These disorders frequently cluster within couples and families worldwide. buff.ly/5EeACOS

Transfer RNA, once considered merely a cellular courier, has now been shown to play a critical role in building one of the cell’s most complex machines—a discovery that could redefine our understanding of gene regulation and disease intervention. buff.ly/SPrbZsA

A new study in Science Advances suggests engineered bispecific antibodies could transform the way we treat one of the world’s most widespread yet underappreciated viral threats. buff.ly/ilCwg9n

New clinical evidence points to a potential breakthrough: a therapy that may not just slow but actually reverse muscle loss in boys with Duchenne muscular dystrophy. buff.ly/Si1fRN1

Parrots don't copy movements. They seem to be using a form of learning thought unique to humans: the ability to observe and copy interactions between others without direct instruction. buff.ly/jRDNsAH

A single one-time gene therapy could free patients with α-thalassemia, a rare and debilitating blood disorder, from the burden of lifelong transfusions. buff.ly/nxmus4X

Long-term remission in multiple myeloma—a blood cancer once considered incurable—is finally becoming a reality. A single infusion of immunotherapy has kept patients healthy for more than five years. buff.ly/ePMJvlu

New data from a gene therapy trial provide the first credible evidence that the progression of Huntington’s disease may be slowed by a single, targeted intervention. buff.ly/Uim6aGy

Cravings feel immediate, even irresistible. Yet behind this lies a mystery: How does the brain transform the feeling of want into the act of consumption? buff.ly/sybOg96
