Scientists have found the oldest sample of animal sperm, concealed in a 100 million-year-old piece of amber. Paleontologists discovered the sample in the reproductive tract of an ancient female crustacean encased in resin — one of several samples of ostracods from Myanmar. The previously unknown species of crustacean, now named Myanmarcypris hui, resembles a modern…… MORE

If we make it to Mars, we’re not going to be able to bring everything humankind needs to stay for an extended period of time — or to construct colonies on the red planet. In order to build shelters and manufacture tools, astronauts may only need to bring one key ingredient — with minerals in…… MORE
For the first time, a planet has been discovered orbiting a white dwarf, also known as a dead star. This exoplanet, a planet outside of our solar system, is the size of Jupiter and it’s known as WD 1586 b. This giant exoplanet zips around the star remnant, which is about the size of Earth,…… MORE
The asteroid strike that doomed the dinosaurs is an event that many people are aware of. It wiped out more than three-quarters of all life on Earth 66 million years ago. But it was only one of the Big Five mass extinctions the planet has experienced since living organisms evolved 3.5 billion years ago, and…… MORE

At an ABC town hall in the crucial swing state of Pennsylvania, the President hit back at a question over his remarks to renowned journalist Bob Woodward that…… MORE
Scientists have successfully created animal surrogate fathers that carry only the genes of donor animals — nicknamed “super dads” — in a step forward for gene editing with potential implications for global food production. Researchers from universities in the United States and United Kingdom produced male pigs, goats, cows and mice whose sperm carry the…… MORE
