Scientists have mimicked the taste receptors on a human tongue to distinguish between more than 30 different kinds of whiskey, The Verge reports.

How it works: The "tongues" are tubes of fluorescent liquid which either glow brighter or become dimmer when they come into contact with a drop of whiskey. Each tube mimics a different taste receptor on the human tongue — sweet, salty, bitter, sour and more. The scientists measure the degree to which each whiskey changes the tubes to identify the type of whiskey being tested.

What's new: This "tongue" method allows scientists to test the overall mixture instead of trying to discern its identity by separating its parts by weight, which is usually how mixtures are identified.

Why it matters: The research team, based at Heidelberg University in Germany, says the technology might eventually be used to distinguish between fake and real drugs.

Why it matters: Several major businesses paused or pulled political donations following the events of Jan. 6, when pro-Trump rioters, riled up by former President Trump, stormed the Capitol on the day it was to certify the election results.

Minority Mitch still setting Senate agenda

Chuck Schumer may be majority leader, yet in many ways, Mitch McConnell is still running the Senate show — and his counterpart is about done with it.

Why it matters: McConnell rolled over Democrats unapologetically, and kept tight control over his fellow Republicans, while in the majority. But he's showing equal skill as minority leader, using political jiujitsu to convert a perceived weakness into strength.
