Now, a new study confirms that this event
Here's the good news, such as it is, for the climate: American coal consumption plunged last year, reaching its lowest level since 1975, as electrical utilities switched to cheaper natural gas and renewables. Over the past decade and a half, coal's collapse has saved tens of thousands of lives nationwide, according to new research, and cut national greenhouse-gas emissions by more than 10 percent
It is well known that the size, shape and structure of organisms can evolve at different speeds, ranging from fast-evolving adaptive radiations to living fossils such as cichlids or coelacanths, respectively.
Astronomers using data from NASA's Transiting Exoplanet Survey Satellite (TESS) have shown that Alpha Draconis, a well-studied star visible to the naked eye, and its fainter companion star regularly eclipse each other. While astronomers previously knew this was a binary system, the mutual eclipses came as a complete surprise.
Classical physics is characterized by the precision of its equations describing the evolution of the world as determined by the initial conditions of the Big Bang—meaning there is no room for chance. Yet our day-to-day experience and intuition are struck by this deterministic vision of the world: has everything really been written in advance? Is randomness nothing more than an illusion? A physicis

UC San Diego researchers studied nearly 900 vertebrate species and found that bats have unusual gut microbiomes that more closely resemble those of birds than other mammals, raising questions about how evolutionary pressures change the gut microbiome.
Gut bacteria help us fight disease and digest food, but not all animals rely on their microbiomes the way we do. A new study comparing the guts of mammals, birds, reptiles, and amphibians shows that birds and bats have unusual microbiomes — probably because they both can fly.
Empathy is defined as the act of recognizing, understanding, and being sensitive to the feelings and experiences of others. Sharing a story about young elephants at a nature preserve, William Shatner argues that empathy is a learned skill, not an inherited trait.

3D Exploded Star A team of astronomers from the Space Telescope Science Institute (STScI), Caltech and Harvard have combined data from three different NASA observatories — the Chandra X-ray Observatory as well as the Hubble and Spitzer space telescopes — to create a 3-D visualization of the Crab Nebula, the remains of a star that exploded in a supernova thousands of light years away. The team is
Here's a strong line from Ricky Gervais's monologue at last night's Golden Globes : "Apple roared into the TV game with The Morning Show , a superb drama about the importance of dignity and doing the right thing, made by a company that runs sweatshops in China." Simple, sharp, speaking truth to power, and nailing an obvious hypocrisy: check, check, check, check. But then Gervais went on to tear i
How can two species look almost exactly the same despite evolving separately for 140 million years? A new study sheds light on a group of sand-dwelling worm species that have hardly changed in appearance since the age of dinosaurs, making them one of the most extreme cases known of slow morphological evolution, also called stasis.

X-ray bursts are highly energetic releases of radiation from the surfaces of neutron stars, triggered by the explosive burning of material accumulated on the surface. It's the same type of burning that happens in the cores of ordinary stars like the sun, but in this case, happening on the surface. Thus, unlike the sun, where it takes hundreds of thousands of years for this radiation to escape—and
Our first child was born at the end of August. I am not a young parent; I was born in 1974, and in the span of this one generation, global carbon levels rose by nearly twice as much as in all of human history before. I teach environmental law, so naturally people get around to asking whether my wife and I struggled with what it means to bring a child onto this troubled planet, and whether it is a
Scientists at the Columbia Center for Children's Environmental Health (CCCEH) have uncovered a link between prenatal exposure to phthalates–a ubiquitous group of plasticizers and odor-enhancing chemicals–and deficits in motor function in girls.
