Multiple Sclerosis: Cell-Catching Implant Helps Identify Successful Treatment in Mice
University of Michigan

A sponge-like implant in mice helped guide a treatment that slowed or stopped a degenerative condition similar to multiple sclerosis in humans. It also gave University of Michigan researchers a first look at how primary progressive multiple sclerosis, the fastest-progressing version of the disease, attacks the central nervous system early on.

HIV Protein Switch May Help Virus Squeeze into Host Cell Nucleus
Pittsburgh Supercomputing Center

How the HIV inserts its capsid into the host cell’s nuclear pore is a puzzle and a therapeutic target. Simulations on the Pittsburgh Supercomputing Center’s Bridges-2 system by a University of Pittsburgh team revealed how changes in the shape of the HIV-1 capsid protein may help the capsid be more flexible.

People Prefer Meat Alternatives if They Are Significantly Cheaper Than Real Meat, Study Shows
Martin-Luther-Universität Halle-Wittenberg

Only a few people fundamentally oppose eating plant-based meat alternatives, a recent survey of 2,100 customers in the US shows. According to the results, the price of meat alternatives is the most decisive factor for their acceptance, while similarity to meat did not matter that much.

Q&A: How Rate of CO2 Rise Can Affect a Global Ocean Current
University of Washington

How fast the level of atmospheric carbon dioxide — and with it, the temperature — goes up matters for the ability of humans and ecosystems to adjust. A slower increase gives humans time to move away from low-lying coasts and animals time to move to new habitats. It turns out the rate of that increase matters for non-living systems, too.
