At Live Science, we delve into science news from around the world every day — and some of those stories can get a little weird. Here are some of the strangest science news articles from this week.
Is the lost city of Atlantis in Spain? A U.K.-based company used satellite images to discover the ruins of what may be Atlantis in Spain. But archaeologists are doubtful: First, Atlantis may not even exist — it's likely that Plato wrote about as an allegory to describe an advanced yet corrupt society. Second, the company claims the ruins date to about 12,000 years ago, but hunters and gatherers lived in Spain at that time, not an advanced maritime city like Atlantis.
How did Knickers, a beast who is 6 feet, 4 inches (194 centimeters) tall at the shoulders, get so big? It's possible that the steer (a male cattle that's been neutered) has a mutation in his growth hormone, an growth biologist told Live Science.
The International Space Station found an unwelcome surprise lurking in its toilets: Four species of previously unknown antibiotic-resistant bacteria. Luckily, these strains aren't virulent. But there is a 79 percent chance they could evolve into something dangerous, so researchers are keeping a close eye on them.
Scientists have figured out how to grow tiny placentas in the lab. These miniorgans are so accurate, they're helping researchers learn how the placenta acts during the first few weeks of pregnancy. In fact, these miniplacentas even secrete hormones that are capable of getting a positive result on an over-the-counter pregnancy test.
A Seattle-based company has combined aspects of a plane, blimp and helicopter to make a plimp airship. This aircraft zooms around by using helium as well as gas-electric hybrid engines and rotational wings with propellers. And, in the case of an engine failure, the plimp airship is able to safely float down, thanks to that helium.
A Nov. 11 seismic event has mystified geologists. The weird occurrence began off the coast of Mayotte, near Madagascar and then circled the entire world, according to National Geographic. Unlike an earthquake, which has many frequencies, this hum rang at a single ultra-low frequency. And it had big effects: Mayotte slid 2.4 inches (6 centimeters) to the east and 1.2 inches (3 cm) to the south.
Neanderthals and the ancestors of modern humans shacked up way more often than was previously realized. It turns out that Neanderthal ancestry is 12 to 20 percent higher in modern East Asians compared with modern Europeans, suggesting that these different species were interbreeding in the Middle East, as well as Europe and East Asia.
