![]() The experiment, which was years in the making, could have implications for fertility treatments and even prevent endangered animals from going extinct - but thorny legal and ethical issues remain around these advances in genetic engineering. Skin cells collected from the tails of male mice were used to generate eggs that were implanted in female mice and resulted in healthy pups with different shades of fur. Scientists were able to create mice from two biologically male parents for the first time. The finding adds more evidence that meteorites carried the building blocks of life to Earth. Meanwhile, scientists studying samples returned from the near-Earth asteroid Ryugu discovered vitamin B3 and an RNA compound called uracil. When the interstellar comet was warmed by the sun’s searing heat, hydrogen trapped inside of it began to escape, propelling the reddish pancake-shaped rock. Now, researchers think they know what caused ‘Oumuamua to go zipping around our sun. Meanwhile, a couple who decided to renovate their apartment kitchen in northern England was surprised to find centuries-old murals depicting a biblical scene.Īn interstellar visitor was observed in our solar system for the first time in 2017.Ībout the size of an asteroid, the mystery object kind of moved like a comet, but it also accelerated - some even thought it was an extraterrestrial spacecraft. Over time, the skies in the paintings became whiter as pollution influenced the light the artists captured. The study team tracked changes in the skylines of the cityscapes, watching as air pollution created by industrial manufacturing increased. Now, researchers have uncovered the scientific cause behind the inspiring “smoke” the artist chased during his London trips: atmospheric change.Ĭlimate scientists studied over 100 works from Monet and British painter Joseph Mallord William Turner, who was active before the Impressionist artist. Impressionist painter Claude Monet was known for the dreamy haze that drifts across many of his works. If you think that’s wild, that’s not the only news in 3D printing: An aerospace startup has fabricated a rocket that had a picturesque night launch this week - but it ultimately failed to reach orbit. Years of work went into the method that resulted in a single slice of cake - a confection that would make Willy Wonka proud. The lasers cooked the different layers of the cheesecake as it printed. They are all subjective and all controversial with some countries feeling that their wonder should be included on the list.The researchers also uncovered a bit of Beethoven’s secret family history hiding in his DNA.Ĭraving a tasty slice of cheesecake filled with all of your favorite flavors? There’s a 3D printer for that.Įngineers at Columbia University assembled and cooked a seven-ingredient vegan cheesecake, including hazelnut spread and strawberry jam, using a 3D-printing machine and laser technology. CNN, USA Today and the BBC have all polled their own 7 Wonders of the World with very different outcomes. There are dozens of 7 Wonders of the World lists from the Industrial wonders of the world (We’ve been to all of them too!) to the 7 Wonders Cities of the World.
