The powerful jaws of tyrannosaurus rex snapped together with such force that they would splinter the bones of the dinosaur’s prey. But to gain such a powerful bite, the king of the dinosaur had to make an evolutionary trade-off: It had to settle for smaller eyes. Based on an analysis of 410 fossilized reptile specimens …
Not just tiny arms: T. rex also had super small eyes to accommodate its big bite Read More »

The asteroid appeared to be shooting off swarms of marble-sized …

Photo: David Taylor/Science Photo Library (PA) Antarctica is home to 90% of the world’s freshwater, trapped in the continent’s massive ice sheets—and the stability of much of that ice is seriously at risk from global warming. Two studies published in the journal Nature this week take a look at how climate change is shaking up …

NEW YORK – Between after-school sports and parents working long hours, is the family dinner becoming more obsolete? Three in five Americans believe every dinner should be a “family dinner” — and just as many wish they could eat more often with their family. In a poll of 2,000 US adults, the average person says …
Earth and its Moon are unique in the Solar System. Earth is the only planet with just one moon, and that Moon is pretty influential. In fact, without the Moon, life on Earth may not have emerged, some research suggests. Couple that with a size ratio unlike any other planet-moon system we’ve seen – the …
Betelgeuse first drew attention in late 2019 when the star, which glitters like a red gem in the upper-right shoulder of Orion, experienced an unexpected darkening. The supergiant continued to grow sun in 2020. Some scientists speculated that the star would explode as a supernova, and they’ve been trying to determine what happened to it …

Betelgeuse, a red supergiant star, appears as a brilliant, ruby-red, twinkling spot of light in the upper right shoulder of the winter constellation Orion the Hunter. However, when viewed close up, astronomers know that it is a seething monster with a 400-day-long heartbeat of regular pulsations. This aging star is classified as a supergiant because …
A team of scientists from Georgia Tech say they’ve built a robot that can move without anything to push against – a discovery that seems to violate the law of conservation momentum. The researchers were able to generate momentum without a surface to push off from by building a robot isolated from outside influences and …
