Science Glance
A mummified wolf pup and caribou believed to have walked Earth over 50,000 years ago were discovered with tissue and fur intact — a remarkable find, Canadian authorities say.
The caribou was found at the site of a 80,000-year-old volcanic ash bed and officials believe it's among the oldest mummified mammal tissue in the world, according to a release.
The head, two front limbs and torso of the caribou were intact. The wolf pup was found with a complete body.
Scientists have discovered an atom filled with atoms. The atom's electrons orbit at such a great distance that there's room for other atoms.
The atoms within the "giant atom" form weak bonds, produ cing a new exotic state of matter -- what scientists have dubbed "Rydberg polarons."
The discovery combines a pair of atomic phenomenon, both of which can only be studied under extremely cold conditions: Bose-Einstein condensates and Rydberg atoms.
For the first time, researchers have used the cloning method that produced Dolly the sheep to create two healthy monkeys, bringing science an important step closer to being able to do the same with humans.
Since Dolly's birth in 1996, scientists have cloned nearly two dozen kinds of mammals, including dogs, cats, pigs, cows and polo ponies, and have also created human embryos with this method. But until now, they have been unable to make babies this way in primates, the category that includes monkeys, apes and people.
Former NASA astronaut Bruce McCandless, the first person to fly untethered in space, died this week at 80 years old, the agency said Friday.
McCandless, who died Thursday, became the first astronaut to fly in space without being harnessed to a space vessel on Feb. 7, 1984, while on a mission aboard the space shuttle Challenger. Other astronauts on the mission used a 70mm camera to capture the moment in a now-iconic photograph, NASA said in a release.
NASA's Cassini spacecraft disintegrated in the skies above Saturn on Friday in a final, fateful blaze of cosmic glory, following a remarkable journey of 20 years.
Confirmation of Cassini's expected demise came about 7:55 a.m. EDT. That's when radio signals from the spacecraft — its last scientific gifts to Earth — came to an abrupt halt. The radio waves went flat, and the spacecraft fell silent.
An enormous black hole one hundred thousand times more massive than the sun has been found hiding in a toxic gas cloud wafting around near the heart of the Milky Way.
If the discovery is confirmed, the invisible behemoth will rank as the second largest black hole ever seen in the Milky Way after the supermassive black hole known as Sagittarius A* that is anchored at the very centre of the galaxy.
Astronaut Peggy Whitson is home safe after spending a record 288 days on the International Space Station.
Whitson touched down in Kazakhstan at 9:21 p.m. EDT on Saturday aboard a Soyuz capsule. Whitson was joined for the trip home by NASA colleague Jack Fischer and cosmonaut Fyodor Yurchikin of Roscosmos.
