Not just tiny arms: T. rex also had super small eyes to accommodate its big bite

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 …

‘Family dinner’ a thing of the past? Average person spends just 3 meals a week with loved ones

NEW YORK – Between after-school sports and parents working long hours, is the family dinner becoming more obsolete?

The Moon Stole Something From Deep Inside Earth Eons Ago, and Scientists Can Prove It: ScienceAlert

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 star had an unprecedented massive eruption

Betelgeuse star had an unprecedented massive eruption

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 …

Hubble Sees Red Supergiant Star Betelgeuse Recovering After Never-Seen-Before Titanic Eruption

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 …

Scientists claim to have physics-defying curved space robot • The Register

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 …
