A visual celebration of the home planet, starting with a view from Earth as seen from Saturn — 870 million miles away — and zooming in close
In this image, acquired by the Cassini spacecraft just this past April 12th, the rings of Saturn dominate the view. But see that little white dot? That’s home — 870 million miles away.
On the morning of the first Earth Day, on April 20th, 1970, a friend and I boarded the IRT subway line in Brooklyn and headed for Manhatta ...read more
As the March for Science has drawn near, scientists and science-lovers across the country have pontificated at length on why they are—or aren’t—marching. But while today’s 400-plus demonstrations around the nation will hopefully resonate with lawmakers, it takes more than rallies to accomplish lasting change. The following is a guest post from Dr. Kira Krend, a biology teacher in Honolulu, HI, on her March for Science—one that she does ever ...read more
Is climate change playing any role in an apparent lengthening of the hurricane season?

It’s way early for hurricane season to start, but that’s precisely what happened yesterday with the formation of Tropical Storm Arlene in the far northern Atlantic. ...read more
The animation, based on data from a NASA airborne observatory, show just how much the state’s snowpack has grown
Snow water equivalent — the water content of snow — in California’s Tuolumne River Basin, as seen in an animation comparing 2015 and 2017. Lighter blue indicates less snow, deeper blue is more snow (see color bar at left). The 2017 snow water equivalent was 21 times greater than 2015, which was the lowest snowpack on record.

A new article posted on preprint site bioRxiv has generated a lot of interest among neuroscientists on Twitter. The article reports the existence of ‘functional connectivity‘ between surgically disconnected distant brain regions using fMRI, something that in theory shouldn’t be possible.
This is big news, if true, because it suggests that fMRI functional connectivity isn’t entirely a reflection of actual signalling between brain areas. Rather, something else must be able ...read more
