“#OPTN-ATG9 interaction accelerates autophagic degradation of ubiquitin-labeled mitochondria” Damaged mitochondria are selectively eliminated via autophagy called mitophagy. In mammalian cells, ubiquitin chains on the damaged mitochondria play critical roles to induce mitophagy. Researchers at Tokyo Metropolitan Institute of Medical Science (TMIMS) discovered that the critical autophagy adaptor OPTN (optineurin) interacts with ATG9A, the leucine zipper…

“#Study suggests less costly approach to pandemic economic stimulus” In late March, as the COVID-19 coronavirus began spreading swiftly throughout the United States, Congress passed a $2 trillion economic stimulus measure that included one-time direct payments to taxpayers, relief for small businesses, and expansion of unemployment insurance, among other provisions. It was the largest economic…
“#Doing more with less: Sperm without a fully active tail move faster and more efficiently, new study finds” Credit: CC0 Public Domain Sperm cells moving their long tail to swim through the body in search of an egg is a familiar image, but a fully ‘powered’ tail may not be the key to success, according…
“#Languages will change significantly on interstellar flights” Artist’s impression of a cylindrical spacecraft’s interior.
