Carlos del Rio, executive associate dean at the Emory School of Medicine, told POLITICO the CDC guidelines do not make sense because individuals who have been in close contact with a confirmed case of Covid-19 for at least 15 minutes could potentially be infected and should be tested.

New York Gov. Andrew Cuomo slammed the change as “political propaganda.” Officials in several other states, including California, Connecticut and Washington, said Wednesday that they would not alter their testing approach to match the new CDC guidelines.

"Suggesting that people without symptoms, who have known exposure to COVID-positive individuals, do not need testing is a recipe for community spread and more spikes in coronavirus," American Medical Association President Susan Bailey said.

The abrupt — and unannounced — changes have already intensified scrutiny of the CDC's independence, and the administration's broader coronavirus response ahead of the November election.

experts are cautioning against going overboard with the “good vibes only” trend. Too much forced positivity is not just unhelpful, they say — it’s toxic

people who habitually avoid acknowledging challenging emotions can end up feeling worse.

"Culturally, we encourage boys and men to adhere to rigid notions of masculinity that emphasize stoicism, self-sufficiency, and control. Men lose their emotional voices early in their lives."

Scientists think the universe is flat, but new observations suggest that we might actually be living in a gigantic sphere. Whoa.

In current quantum field theory, causality is typically defined by the vanishing of field commutators for spacelike separations. Two researchers at the University of Massachusetts and Universidade Federal Rural in Rio de Janeiro have recently carried out a study discussing and synthesizing some of the key aspects of causality in quantum field theory. Their paper, published in Physical Review Letters, is the result of their investigation of a theory of quantum gravity commonly referred to as "quadratic gravity."

One of the great counterintuitive puzzles of quantum mechanics is wave-particle duality. This is the phenomenon in which objects behave both like particles and like waves. Numerous experiments have shown that a single particle—an electron or a photon, for example—can interfere with itself, like a wave. The double slit experiment, in which a particle passes…

"The President of the United States is sabotaging a basic service that hundreds of millions of people rely upon, cutting a critical lifeline for rural economies and for delivery of medicines, because he wants to deprive Americans of their fundamental right to vote safely during the most catastrophic public health crisis in over 100 years," Andrew Bates, a spokesperson for Joe Biden's campaign, said in a statement reacting to Trump's comments.
