Watch: Animation of satellite images shows smoke from the Brian Head fire drifting across much of Utah and beyond
Super dry conditions and winds gusting to more than 40 miles per hour yesterday have fanned Utah’s Brian Head wildfire, reportedly sending flames shooting 100 feet into the air.
Those flames lofted giant plumes of smoke that were easily seen by the GOES-West weather satellite. You can see it happening in the animation above, which I created using imagery acquired by the satellit
The “hardness” of drugs is a concept that makes intuitive sense, but is difficult to put into precise terms. “Hard” drugs are those which are viewed as more addictive, more potent and more toxic than the comparatively benign “soft” variety. The concept has a normative aspect: “hard” drugs are bad, and you should avoid them, even if you use soft drugs.
In the new paper, Slovakian researchers Peter Janik et al.

Using a special interferometer and data from the 1990s, two Canadian researchers say that they can explain why the sky seems so much brighter
The origin of this proverb traces back centuries, but time has hardly tarnished its relevance. It’s a warning every generation would do well to heed: Mismanaging precious commodities today will lead to an impoverished future. It’s so simple. It’s so true. It’s so often ignored.
Case-in-point: global industrial fishing operations. Over the past decade, fishing fleets simply threw away more than 10 percent—enough to fill 4,500 Olympic-sized swimming pools—of the wo
A dramatically detailed animation from the new GOES-16 satellite shows Hurricane Dora swirling in the Pacific
Click on the screenshot above and say hello to Dora, the first storm of 2017 in the Western Hemisphere to reach hurricane strength.
The imagery that went into the animation comes from NOAA’s new GOES-16 weather satellite. This is the first hurricane that the satellite has tracked since it was launched in November of 2016.
As I’m writing this late on the afternoon of Monday, June 26th, Dora is a Category 1 hurricane
Before I get into the details, you might be wondering how images of far away planets fit in a blog dedicated in large measure to the science of our planet. That word, ‘planet,’ get
Here’s a few observations on essays and on marking them.
1. Marking Essays is Subjective
This is a bit of a truism: it’s fairly obvious that not everyone will agree on how to grade an essay down to the exact mark. Unlike with, say, a multiple-choice exam, marking an essay is not a mechanical process. But it’s easy to forget this when the marks are there in black and white (or r
Humans seem obsessed with melody and rhythm. But when did it begin in hominin history? What purpose does it fulfill? And does music have a dark side?
The first bands started gigging at least tens of thousands of years. Archaeologists have found 40,000-year-old flutes carved from bird bones. The
This idea that “sex sells” has hung around for more than a century, and by this point it’s almost accepted as a doctrine. And those are exactly the types of claims researchers love putting to the test.

Summer is finally here in the Northern Hemisphere. The days are long, the weather is warm, and the water is inviting. It’s also time for o
That’s exactly the case for MACS 2129-1, a galaxy lensed by a massive foreground galaxy cluster. Using the Hubble Space Telescope, astronomers have managed to catch a glimpse of this unusual object, which appears to be an old, “dead” galaxy that’s already stopped making new stars just a few billion years after the Big Bang. Not only is this galaxy finished with its
So what’s the reason?
Biologists have been asking that question for quite some time, and their hypotheses are perhaps just as varied as the eggs themselves. Scientists in the past have concluded that cliff-dwelling birds lay
Researchers from the University of Central Florida and National Taiwan University designed an anti-reflective coating that was inspired by moth eyes. The coating reflects about 10 times less light than the best anti-glare technique in commercial use.

Phoenix was projected to reach of 120 degrees Fahrenheit, a near-record for the desert city, and hot enough that small planes cannot generate enough lift to fly. Phoenix and other cities have experienced similar conditions before, but only rarely—for now. The grounded passengers got to sit inside an air-conditioned terminal, at least. But in other parts of the world where temperatures are set to soar regularly above 1

Scientists have tracked exchange and trade through the archaeological record, starting in Upper Paleolithic when groups of hunters traded for the best flint weapons and other tools. First, people bartered, making direct deals between two parties of desirable obj
