Major cities on the U.S. Atlantic coast are sinking, in some cases as much as 5 millimeters per year – a decline at the ocean’s edge that well outpaces global sea level rise, confirms new research from Virginia Tech and the U.S. Geological Survey. Particularly hard hit population centers such as New York City and Long Island, Baltimore, and Virginia Beach and Norfolk are seeing areas of rapid “subsidence,” or sinking land, alongside more slowly sinking or relatively stable ground, increasing the risk to roadways, runways, building foundations, rail lines, and pipelines, according to a study published today in the Proceedings of the National Academies of Sciences.
Frequent insulin injections are an unpleasant, albeit necessary reality for many patients with type 1 diabetes. However, new technology could create a different reality for these patients by treating the disease in one fell swoop.
Using lab-made cells, Harvard Med researchers identify how the immune system neutralizes herpesvirus. Study maps, for the first time, the maneuvers used by virus and host in the cell nucleus. Findings could inform design of new treatments for herpes and other viruses that replicate in the same way.
It’s fairly well-known that a drought in southern California in the mid-1970s led to a ban on filling backyard swimming pools, and these empty pools became playgrounds for freestyle skateboarders in the greater Los Angeles area.
Living through a historic pandemic while handling the stress of the first year of college sent one-third of students in a new study into clinical depression. That’s double the percentage seen in previous years of the same study.

In a groundbreaking study, a team of Georgia Tech researchers has unveiled a remarkable discovery: the identification of novel bacterial proteins that play a vital role in the formation and stability of methane clathrates, which trap gigatons of greenhouse gas beneath the seafloor. These newfound proteins not only suppress methane clathrate growth as effectively as toxic chemicals used in drilling but also prove to be eco-friendly and scalable. This innovative breakthrough not only promises to enhance environmental safety in natural gas transportation but also sheds light on the potential for similar biomolecules to support life beyond Earth.
