Scientists have discovered a new species of tiny tyrannosaur that lived some 95 million years ago in what’s now Utah. The find helps fill a frustrating gap in the fossil record at a critical time when tyrannosaurs were evolving from small, speedy hunters, into the bone-crushing apex predators we know so well.
The new dinosaur has been dubbed Moros intrepidus, and its name means “harbinger of doom.” The creature, known only from a leg bone and some various teeth, weighed u ...read more
Nearly 66 million years ago, most living things on Earth died. Most researchers agree that the prime culprit was an asteroid that struck Mexico’s Yucatan Peninsula, leading to the mass extinction that took out most of the dinosaurs. But in a new research published Thursday, two independent research groups are making the case that enormous volcanic eruptions in India likely contributed to the demise of life, too.
The findings shed light on not only one of the most famou ...read more
Far from Earth, a tiny spacecraft is going to punch an asteroid tonight.
Hayabusa2 is swooping close to Ryugu today to collect asteroid dust. The JAXA spacecraft has spent the last day leaving its usual orbit around the asteroid to zoom in close. In just few hours, it will be close enough to touch Ryugu.
But it won’t stay long. The touchdown is more of a quick tag, and Hayabusa2 will stay just long enough to fire a tiny bullet into the asteroid’s surface, in order to stir up mater ...read more
Researchers have synthesized new ingredients for the blueprint of life. Steven Benner, a pioneer in the field of synthetic biology, and his team created four new DNA letters, according a study out today in the journal Science. The new eight-letter genetic system, dubbed “hachimoji” (hachi meaning eight in Japanese and moji meaning letter), doubles the number of building blocks for life.
“A lot of people have hinted ...that the natural letters aren't the only sol ...read more
The Israeli spacecraft Beresheet launched is set to launch this evening on a trip to the moon, where it hopes to touch down in two months. This will be the first attempt at a lunar landing by a private company, and it's also the first launch by an Israeli spacecraft. Beresheet will take off from from Cape Canaveral on one of SpaceX’s Falcon 9 rockets at 8:45 Eastern time tonight.
Small Craft, Big Expectations
Beresheet’s creators are Israel Aerospace Industries and th ...read more
