The fearsome family of dinosaurs topped by Tyrannosaurus rex began with a miniature version of the tyrant that was only the size of a human being.
The new find from China was made public Thursday in a press conference and is already rewriting T. rex’s evolutionary story. It’d long been thought that the multiton dinosaur’s massive skull, dinky arms, and runner’s legs evolved as a set of compromises necessitated by its increasingly massive size. The new Raptorex kriegsteini proves that the T. rex’s distinctive features predated its scaling up.
First-Gen T. Rex Was No Bigger Than You
Planck telescope's first glimpse
The European telescope sent far from Earth to study the oldest light in the Universe has returned its first images.
The Planck observatory, launched in May, is surveying radiation that first swept out across space just 380,000 years after the Big Bang. The light holds details about the age, contents and evolution of the cosmos.
Color-blindness Cured by Gene Injection in Monkeys
A simple injection of cells has cured monkeys of color-blindness—giving a green light to future research into improving human vision with gene therapy, a new study says.
Calling the procedure his gene therapy "dream," researcher Jay Neitz said that "ultimately this could be a tool that could cure all sorts of eye diseases."
Earth-like planet discovered outside solar system
Astronomers have discovered an Earth-like planet outside the Solar System, 'shortening' the odds that alien life could exist. A new study of the planet, which orbits a star 500 light years away, has shown that its density is similar to Earth's, indicating it is a solid rocky world.
Known as COROT-7b, it was discovered in February this year by the European space telescope COROT, which had been tracking the star it circles.
First Genetic Link Between Reptile And Human Heart Evolution Found
Scientists at the Gladstone Institute of Cardiovascular Disease (GICD) have traced the evolution of the four-chambered human heart to a common genetic factor linked to the development of hearts in turtles and other reptiles.
Galaxy's 'cannibalism' revealed
The vast Andromeda galaxy appears to have expanded by digesting stars from other galaxies, research has shown. When an international team of scientists mapped Andromeda, they discovered stars that they said were "remnants of dwarf galaxies".
The astronomers report their findings in the journal Nature.This consumption of stars has been suggested previously, but the team's ultra-deep survey has provided detailed images to show that it took place.
Scientists identify coldest place on earth

A team of American and Australian scientists identified Ridge A from satellite imagery and climate models during an exhaustive search for the best observatory site in the world.
