Cells rely on a natural cleanup system to prevent damaged materials from accumulating inside them. Known as autophagy, this process collects defective proteins and other cellular waste, packages them into specialized compartments, and breaks them down into basic molecular components that can be reused. This recycling system helps protect cells…
A furry predator that lived 165 million years ago is offering scientists an unexpected glimpse into the evolution of mammals. Known as Megacauda sungei, this ancient hunter measured only about half a meter (20 inches) from nose to tail, yet it was remarkably large compared with most of its Jurassic…
Scientists have reconstructed a remarkably detailed family tree of cells in a developing mouse embryo, tracing their origins back to the moment a fertilized egg first divided into two cells. Using an innovative DNA recording technology, the researchers followed how those early cells multiplied, developed specialized roles, and eventually helped…
A particle does not have to pass through a magnetic field to be influenced by it. That surprising feature of quantum physics has now been recreated by researchers at the University of Oxford, who used a hybrid quantum computer to demonstrate how an invisible magnetic influence can bring a simulated…
Feeling overwhelmed by stress or struggling to adjust when things go wrong? Everyday habits such as eating a nutritious breakfast, getting regular exercise, and sleeping enough may play an important role in how well your mind handles difficult situations. New research from Binghamton University suggests that these healthy routines are…
Scientists have spent decades studying the brain’s cells, connections, genes, and proteins. Yet another essential part of brain biology has received far less attention: lipids. These fatty molecules make up the membranes surrounding neurons, contribute to the myelin insulation that protects nerve fibers, and play important roles in communication between…
Scientists have discovered a surprising ability of light that allows it to develop spinning patterns as it moves through empty space, without relying on special lenses, mirrors, or materials. The finding reveals that light possesses a hidden geometric structure that can influence its behavior in ways researchers previously thought were…
Scientists have developed a way to coat mitochondria, the tiny structures that produce energy inside our cells, with advanced materials without interfering with their function. The achievement could eventually help researchers develop new approaches to treating diseases caused by malfunctioning mitochondria. The research was conducted by IRCCS Fondazione Istituto Neurologico…
The FDA has approved the first drug designed to directly treat Alexander disease, an extremely rare neurological disorder that progressively damages the nervous system and can be fatal. The treatment, called Zanvastro, represents a major advance for patients who previously had no options beyond managing their symptoms. Alexander disease can…
Just two weeks after reaching orbit, Europe’s new Copernicus Sentinel-3C satellite has delivered its first spectacular images of Earth, revealing everything from the snow-covered Alps to the frozen Arctic and the brilliant turquoise waters of the Caribbean. But the satellite is doing much more than taking beautiful pictures. Its instruments…
The real problem with smartphone use may not be how many hours people spend staring at their screens. What they do during that time could be even more important. Researchers at Semmelweis University have found that problematic smartphone use is closely associated with poor self-control and a strong fear of…
The calorie count printed on a food package might seem like a straightforward measure of how much energy you will get from eating it. But the number on the label does not necessarily match the calories your body actually absorbs. One reason is that digestion involves more than just breaking…
More than 2 billion years ago, Earth underwent a dramatic transformation as oxygen began building up in its atmosphere. But that change left scientists with a major mystery: How did the planet maintain enough oxygen to remain habitable over millions of years? Researchers have now uncovered evidence that the answer…
Octopuses, squid, and cuttlefish possess some of the most sophisticated nervous systems in the animal kingdom, giving them remarkable abilities such as solving problems and rapidly changing their appearance to blend into their surroundings. But how did these extraordinary capabilities evolve? Scientists have uncovered a surprising clue that may lie…
Popular GLP-1 medications used for weight loss and type 2 diabetes (such as Ozempic, Wegovy, Mounjaro, Zepbound, Victoza, and Trulicity) have been linked to an unexpected problem involving fingernails. A multinational study found that people taking these drugs were more than four times as likely to report nail detachment, a…
What if some of the changes we associate with aging begin with the loss of a single protein deep inside the brain? Scientists investigating that possibility found that restoring a protein called Menin in older mice improved memory, balance, bone mass, and skin thickness in just 30 days. Even more…
