Here's a video look at fossil pieces of Dreadnoughtus, the huge sauropod dinosaur found in Argentina recently.

If your buzz from Valentine's Day hasn't worn off just yet, here's news that will do just that. The folks at MinuteEarth this week look at how rare monogamy actually is among the sexes of Earth's species.

Author Helen Yoest shares insights from her book Plants with Benefits in this interview. After reading this, head to the nearest produce section and select just the right ingredients to make a memorable Valentine's Day.

Only the edge of the frill on back of the skull was visible when Currie first came upon it, but eventually he dug out a nearly complete, articulated specimen. The only bones missing were the dinosaur's front legs.
Currie is professor of Dinosaur Paleobiology at the University of Alberta, in Edmonton, and now, after three long years of lab preparation, he and his staff are proudly showing off their prize dinosaur and getting it ready to put on display at the U of A Museums’ Galleries starting February 6th. "Baby" as the dinosaur is affectionately called, is the most complete baby ceratopsian dinosaur in the world.

But this week surgeons at University Hospital Leuven in Belgium announced the discovery of a new ligament in the knee. Called the anterolateral ligament (ALL) the newly discovered body part attaches between the lower end of the femur and the head of the tibia, reinforcing the connection between the two bones. The unknown ligament came to light as the doctors investigated the causes of difficulties patients suffered during rehabilitation from ACL tears, a common injury among some athletes.
Interestingly, it was a paper written by a French surgeon in the 19th century that led the doctors to the ligament. The author of an 1879 paper postulated the ALL's existence but it took until now for it to be actually located. The two doctors who discovered it say the ligament exists in about 97 percent of all patients.

But headlines today just add more fuel to the King Tut woe fire (so to speak). Tests done on a small fragment of Tut's mummy that is held in Great Britain show that his mummy caught fire. And that fire, researchers believe, occurred after Tut was mummified and entombed in his sarcophagus through spontaneous combustion from the mixture of embalming oils, wrapping fabric and oxygen. A virtual autopsy done as part of this research also concludes that Tut died from being run over by a chariot. All in all, not a very good day of news for young King Tut.
For a long time, scientists have known a major volcano complex was under the Pacific Ocean off the coast of Japan. But upon further inspection, they've discovered it's one huge volcano, measuring 280 miles by 400 miles across. You can read more about this huge discovery right here.
Courtesy Welome ImagesResearchers from the University of Amsterdam have found that nanomachines work more efficiently when water is added as a "lubricant". Nanomachines are structures just one molecule in size (a few dozen atoms or so) that do work. When researchers added a small amount of water to the solvent that surrounded the nanomachines, the machines moved much faster.
Discovering how to optimize these tiny machines is important for the development of things like molecular computers and surfaces that can change properties.
Researchers are developing nanobots that can destroy plaque build-up in arteries. These nanobots have a magnetic core, which allows physicians to track their position in the bloodstream in real-time. The physicians can then control the bots' movements and plaque destruction via a remote monitor, like an MRI.
This means that, in the future, plaque build-up could be removed without surgery, or other invasive medical procedures. Pretty cool!
