A graph of Covid rates. It's more complex than can be described here, but the important bit is that the rates have gone up a lot since late July, nearly to the heights of last winter.

Hey, so...Covid rates have gotten real high. Maybe change your behavior to fit this new risk profile? Stop eating indoors at restaurants, mask on mass transit, that kind of thing?

“There is a cult of ignorance in the United States, and there has always been. The strain of anti-intellectualism has been…nurtured by the false notion that democracy means that 'my ignorance is just as good as your knowledge.'”

Reading University research shows turbulent flights to increase University of Reading research shows that clear-air turbulence, which is invisible to aircraft, is set to get worse.

Our new study finds that the upper atmosphere is becoming more sheared and less stratified because of climate change. Both these changes are making the atmosphere less stable and more conducive to turbulence.

Improving Oversight of Federal Grantmaking By the authority vested in me as President by the Constitution and the laws of the United States of America, and to improve the process of Federal

This is a shocking executive order that undermines the very idea of open inquiry. It turns federal grants into dispensations, subject to arbitrary and capricious withdrawal should the recipient say or believe the wrong things.

Actually, the best protection is to *combine* vaccines with N95-wearing, indoor space ventilation and indoor air filtration.

All of those things will reduce your risk of developing Long COVID, which can damage your heart, brain and other organs.

Dr. Woodrum’s story is inspirational. It reminded me why space is worth exploring: love.

5 big unanswered questions about the origin of life Somewhere, at some point in the history of our Universe, life arose. We're evidence of that here on Earth, but many big puzzles remain.

5 big unanswered questions about the origin of life

It's 2025, and Earth is still the only example we have of a planet inhabited by life.

Here are 5 big questions we're seeking to answer about how it came to be, as well as finding life elsewhere.

A field of galaxies scattered across the deep black of space. It is filled with galaxies of many shapes, sizes and colors, as well as the multi-colored points of stars. To the lower left is a region filled with the hundreds of golden glittering gems of a distant galaxy cluster. In the foreground, below and left of center, two blue spiral galaxies look like eyes to the left of the entangled mass of a triple merger. A few bright blue points of foreground stars pierce the glittering tapestry.

A field of galaxies scattered across the black of space. It is filled with galaxies of many shapes, sizes and colors, as well as the bright multi-colored points of stars. The image focuses on a collection of interacting galaxies connected by delicate streams of stars. Like spider silk, these stellar bridges link the large elliptical to the few larger galaxies beneath.

A tapestry of glowing tan and pink gas clouds with dark dust lanes. In the lower right, the Trifid Nebula resembles a small flower in space. Its pink gas petals are surrounded by blue gas, and streaked with dark veins of dust. To the upper left, the larger Lagoon Nebula stretches wide like a churning sea of magenta gas, with bright blue, knotted clumps sprinkled throughout

Dense cluster of bright blue stars shining like beacons against wispy nebula cloud of orange and blue. The background is filled with countless smaller stars.

New model helps to figure out which distant planets may host life As NASA rolls out more powerful telescopes in the future, scientists will need a way to determine where to point them. A new approach could help.
