Using DNA collected from the remains of frozen woolly mammoth, scientists will try and bring back the extinct creatures. Well, sort of... It may take about six years and the animal will be a new, not exact version of the woolly mammoth that walked the planet about 4000 years ago.The elephant is a relative of the woolly mammoth. Using DNA collected from teeth, tusks, hair of the woolly mammoth, scientists plan to add elephant DNA and place a seeded embryo into an Asian elephant to carry until birth. More like an elephant, the new creature would be able to live in colder climates, thanks to the DNA from the woolly mammoth.

Scientists in Germany and New Zealand are training cows to use a "toilet" to urinate. So far, 11 out of 16 calves have successfully been potty-trained. Why train cows to use a specific area, a fenced in area with artificial grass? It is believed that the "mooloo"", as the area has been called, can help the environment. It is estimated that cows urinate about 8 gallons a day! That's a lot of nitrogen that turns to ammonia that is harmful to water supplies.If cows can also be trained to do ALL their bathroom needs in a mooloo, the manure can be harvested to create energy.

Did you know that there is a space cemetery? Actually the place is called Point Nemo (meaning "no one" in Latin). Located in a remote area of the Pacific Ocean, and about 1400 miles from the closest island, it is here where scientists direct space trash. Since 1971, approximately 260 pieces of space crafts, including the Russian space station Mir and a Chinese space station called Tiangong-1, have been sent. Much of the space trash disintegrates on entry but still lots of pieces reach the "space cemetery".
