Rescuing Eggs from Dead Sharks Yields Live Sharks, Hope for Endangered Species

The Guardian – All of this work has culminated in our recent publication of a paper in the journal of Ocean and Coastal Management, detailing the project. To date, a total of 689 eggcases have been recovered from dead sharks at the market; of these, 278 have developed and hatched out successfully with 237 S. canicula and 41 S. stellarisreleased back into the wild. A further four S. stellariswere retained by the aquarium for educational display purposes. | go to source

Bloodless Star Trek Surgery Possible Thanks to Molecular Surgery

Dang it, Jim, I’m a doctor, not a butcher!  That’s what Dr. McCoy of Star Trek might say if he had to do surgery in the 21st century.  Well, soon, Dr. McCoy might feel right at home, as the potential for ‘bloodless’ surgery might now be possible thanks to molecular surgery.

‘Molecular surgery’ reshapes living tissue with electricity but no incisions – Science Daily
American Chemical Society – Traditional surgery to reshape a nose or ear entails cutting, sometimes followed by long recovery times and scars. Now, researchers have developed a ‘molecular surgery’ process using tiny needles, electric current and 3D molds to quickly reshape living tissue with no incisions, scarring or recovery time. It shows promise as a noninvasive alternative to laser eye surgery. The researchers will present their results today at the American Chemical Society (ACS) Spring 2019 National Meeting & Exposition.  “We envision this new technique as a low-cost office procedure done under local anesthesia,” says Michael Hill, Ph.D., one of the project’s principal investigators, who will discuss the work at the meeting. “The whole process would take about five minutes. | go to source

Artificial Joy, Scientific Fake Facts

Joy is a Spark, Literally, and Scientists Can Deliver it to You
PG Newser – If you want to be happy, if that’s all you want, and you don’t care why, and you don’t care how, try new spark joy, though it’s not been officially named spark joy, even though that would be a great name for it.  Researchers that haven’t  been identified in the Discover Magazine article have figured out how to make you happy with just a spark, and there’s video proof to boot.
Discover Magazine – Researchers say they’ve found a remarkably specific means of triggering the electrical fireworks that add up to happiness in our brains. By electrically stimulating a brain region known as the cingulum, scientists created spontaneous laughter and a sense of calm and joy in three different patients. | Get the Full Story

Quantum experiment suggests there really are ‘alternative facts’

NewScientist – There are no objective facts in the world. This isn’t a statement about fake news. Rather, it is the implication of an experiment that suggests the nature of reality depends on who is looking. The work is rooted in thought experiments about the nature of quantum mechanics, but this is the first time one has been done in the lab, with potentially profound implications. “I am very excited about it,” says theorist Carlo Rovelli at Aix-Marseille University in France. | Get the Full Story […] | go to source
