Trump Is Campaigning on a Platform of Abject Failure

President Trump has laid out his case for reelection. In a series of speeches over the past several days, the president has spelled out, or at least gestured toward, the major themes of his coming campaign. There will be other themes, to be sure—mostly, one presumes, attacks on Joe Biden—but the president's recent speeches in Tulsa, in Phoenix, and at Mount Rushmore all outline what appear to be

Pink Ice in the Alps Could Signal Acceleration of Climate Change

For decades, climate scientists have been tracking troubling changes in glaciers around the world.

Norovirus has two alternative capsid structures which change before infection

Human noroviruses are a major cause of gastroenteritis outbreaks worldwide. They cause approximately 200,000 deaths each year in developing countries. However, no effective vaccine or antiviral agent for noroviruses yet exists because cell culture methods to produce noroviruses are very limited and there is a lack of the viral structural knowledge about the virus.

Scientists synthesize novel artificial molecules that mimic a cell membrane protein

In higher organisms, cells and organelles are surrounded by a membrane, which plays a crucial role in not just creating a barrier from the external environment but also mediating exchange of fluids, electrolytes, proteins, and other useful material.
