Six major hurricanes that engulfed the Atlantic Basin in 2017 were a devastating reminder of the vulnerability of coastal communities, where more than half the U.S. population resides.

Concerns about biodiversity tend to focus on the loss of species from ecosystems, but a new study suggests that the loss of variation within species can also have important ecological consequences.

Researchers at Washington University School of Medicine in St. Louis have identified a way to prevent fat cells from growing larger, a process that leads to weight gain and obesity. By activating a pathway in fat cells in mice, the researchers found they could feed the animals a high-fat diet without making them obese.

La agricultura es el motor económico que impulsa las Grandes Llanuras, la vasta extensión de praderas sin árboles que cubre partes de 10 estados y donde la próxima sequía puede aparecer sin advertencia. Ahora hay una nueva y poderosa herramienta para ayudar a proporcionar a agricultores y ganaderos en los áridos estados del oeste de los Estados Unidos indicios tempranos de sequías que se aproximan.

When signals between the brain and one eye go awry, input from the other eye can become predominant, a condition called amblyopia or “lazy eye.” Amblyopia is common and it is typically treated by forcing the less dominant eye to adapt, either through lab-based training or wearing an eyepatch. But new research suggests that people may be able to use wearable augmented-reality technology to reduce this visual discrepancy as they go about everyday activities.
