Genetic material from 161 modern breeds helped a team of researchers at the National Human Genome Research Institute (NHGRI) of the National Institutes of Health assemble the most comprehensive evolutionary tree of dogs. The results are published in the journal Cell Reports. Representatives from each of the 23 clades of …

If you’re looking for an Earth-like planet with an atmosphere, you need only go outside. Alternatively, you could travel some 39 light-years toward the constellation Vela. That’s where astronomers have discovered an exoplanet called GJ 1132b, which appears to have an atmosphere. While it might not be particularly hospitable to …

Paleontologists have unearthed the remains of a previously unknown slug-like creature that lived during the Early Ordovician epoch, 478 million years ago. The discovery, reported in the journal Nature, sheds new light on the earliest stages in the evolution of mollusks, a group of invertebrates that includes clams, snails and …

Astronomers announced several months ago that there is most likely a small Earth-like planet in orbit of Proxima Centauri. That’s a big deal because Proxima Centauri happens to be the closest star to Earth, at just a bit over four light years away. That’s still an insurmountable distance for human …

A team of researchers at Washington University in St. Louis has taken images of a laser pulse generating an optical Mach cone: the equivalent of a sonic boom, but for light. To make an optical Mach cone, a pulse of light would need to be traveling faster than the waves …

Anyone who knows me knows that I’m a big fan of reading Google patents — or, when I’m feeling lazy, reading Bill Slawski’s analysis of them over on his blog, SEO By The Sea. I also have a particular interest in those involving entities, as they are (to me at least) …

A new analysis of Chusang, an archeological site on the high-altitude Tibetan Plateau, suggests that permanent residents may have set up camp thousands of years sooner than previously thought. These fossilized human footprints near Chusang, Tibet, were made between 13,000-7,400 years ago, according to a new analysis. Image credit: Mark …
