Play is widespread, but far from ubiquitous, across the animal kingdom. Especially common in mammals, play is also known to occur in taxa as diverse as birds, fish, octopuses, and even insects. But what is its function, given that natural selection never selects fun for its own sake? One prominent hypothesis is that play is beneficial to individuals because it allows them to practice skills needed later in life. Now, a study in Frontiers in Ethology has shown that male baby chickens play far more than females. This result is of interest given that domestic ...

Medical College of Georgia scientists report that a gene previously implicated in the development of atherosclerotic lesions in coronary arteries could be key to understanding why many people don’t benefit from the most used therapy for neovascular age-related macular degeneration (AMD), a leading cause of blindness. AMD is a condition characterized by abnormal blood vessel growth in the back of the eye. It is highly prevalent in the elderly and people with diabetes, obesity, and many other chronic metabolic diseases. Excessive vascular growth damages the macula, the part of the eye that translates light into image signals. Anti-VEGF therapy, which blocks vascular ...

Osaka, Japan – It might start simply, with a cough or sneeze…but in some cases, the flu virus can make its way to your brain, causing serious symptoms or even death through a disease known as influenza-associated encephalopathy (IAE). Now, in a study published in Acta Neuropathologica, researchers have revealed that IAE may be caused by the virus entering the brain through a specific cell type, and have identified possible treatment strategies. Although IAE is increasingly common, surprisingly little is known about ...
