Artificial cell membrane channels composed of DNA can be opened and locked with a key
Just as countries import a vast array of consumer goods across national borders, so living cells are engaged in a lively import-export business. Their ports of entry are sophisticated transport channels embedded in a cell's protective membrane. Regulating what kinds of cargo can pass through the borderlands formed by the cell's two-layer membrane is essential for proper functioning and survival.
Research documents domestic cattle genetics in modern bison herds
A new study published in the journal Scientific Reports has revealed the strongest evidence to date that all bison in North America carry multiple small, but clearly identifiable, regions of DNA that originated from domestic cattle.
Machine learning framework IDs targets for improving catalysts
Chemists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a new machine-learning (ML) framework that can zero in on which steps of a multistep chemical conversion should be tweaked to improve productivity. The approach could help guide the design of catalysts—chemical "dealmakers" that speed up reactions.
Strong solar flare erupts from sun
