Adding pink seaweed to cow feed eliminates their methane emissions

One of the major contributors to greenhouse gases is the methane that cows belch up as they break down cellulose, but five years ago, research from Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO) found that adding small amounts of a pink seaweed called Asparagopsis to cows' diets eliminated the gut microbes responsible for ...

A deep dive into how parasites hijack our behavior and how we evolved to resist them

On Slate Star Codex (previously), Scott Alexander breaks down Invisible Designers: Brain Evolution Through the Lens of Parasite Manipulation, Marco Del Giudice's Quarterly Review of Biology paper that examines the measures that parasites take to influence their hosts' behaviors, and the countermeasures that hosts evolve to combat them.

Snail slime inspires new super-strong reversible glue

Snail slime -- called an epiphragm -- is an incredibly strong yet reversible adhesive. Now, University of Pennsylvania scientists have developed a new kind of glue that employs the same mechanism as the epiphragm. The new material dries like superglue but once wet, it loses its adhesion. For years, scientists have explored adhesions inspired by nature ...

Breakthrough programmable computer made from DNA running chemical software

For more than two decades, researchers have explored using DNA as a chemical computer. Until now though, DNA computers have only been capable of solving whatever mathematical problem they were built to tackle. Now though, researchers have demonstrated a more general-purpose DNA computer that can run a variety of chemical "programs." From Caltech:
