Millions of years ago, our ancestors, like us today, had to contend with viruses. No doubt the infections were unpleasant for them at the time, but their suffering wasn’t for naught — some of those viruses left traces in our DNA. And, according to scientists at the Francis Crick Institute, these remnants may aid the body’s immune response to cancer today. Discovering Ancient VirusesWhile studying lung cancer in mice and in human tumor samples, the team found that immunotherapy treatment se ...read more
A mainstay of the December night sky, the Geminids meteor shower first appeared in the mid-1800s, and it’s grown more impressive in the ensuing years. It now features up to 120 meteorites an hour given clear skies. A new study may have found that the shower originated in some type of catastrophic collision. This differentiates it from most showers, which come from icy comets that pass close to the sun, that then melts and releases particles.Read More: The Asteroids We Should Watch Out ForAn As ...read more
Take one look at a fossilized Archaeopteryx, and you’re bound to be confused.

The mix of traits is so strange that even paleontologists have struggled to classify the creature.Having been described as both a birdish dinosaur and a dinosaur-like bird, Archaeopteryx, whose name translates to “old wing,” is best understood as one of many transitional forms that brid ...read more
Alcohol use disorder, the medical diagnosis for alcoholism, affects about 10 percent of the U.S. population, or 29.5 million people. Yet, doctors wanting to treat this condition have only a handful of medications at their disposal, including such drugs as disulfiram, Acamprosate and naltrexone.Disulfiram makes people violently ill if they drink. Acamprosate is powerfully tranquilizing. And naltrexone suppresses the opioid system, which can reduce cravings in both alcoholics and opiate users. Sti ...read more
Within rocks found in the Lower Cretaceous Wessex Formation dating between 66 and 145 million years, paleontologists excavated a new species of ankylosaur on the Isle of Wight. The previously unknown giant reptile was dubbed Vectipelta barretti and is the first armored dinosaur found on the British island in over a century. The find shines light on the diversity of the ankylosaur fauna during the early Cretaceous period in England, which was published this month in the Journal of Systematic P ...read more
