Elephants in Mozambique have evolved without tusks, likely as a response to poaching, a study in Science suggests. Poaching led to a huge drop in the numbers of tusked elephants, resulting in more female elephants showing mutations in a pair of tooth genes that are responsible for them being tuskless.
A technical high school in Massachusetts recently reopened its on-campus restaurant, Skyline Bistro, to the public. Kevin Layton, chef instructor/department head, says the school's culinary students also are being recruited by local restaurants due to workforce shortages, and he hopes students will be ready by next month to begin to help fill those gaps.
A ruby that dates back 2.5 billion years contains graphite, a form of carbon that could be a part of microbial life, a study in Ore Geology Reviews suggests. "Based on the increased amount of carbon-12 in this graphite, we concluded that the carbon atoms were once ancient life, most likely dead microorganisms such as cyanobacteria," said Chris Yakymchuk, the study's author.
Scientists put an implant in the brain of a woman who lost her sight 16 years ago and restored some of her vision, according to findings reported in The Journal of Clinical Investigation. The woman can see shapes with the help of a special visual prosthesis in conjunction with the implant in her visual cortex.
Paleontologists found the fossil remains of about 80 dinosaurs in a single site in Argentina, suggesting that the long-necked sauropods were part of a herd. The site, studied over the course of 15 years, yielded fossils of many different age groups, as well as 100 eggs, of the Mussaurus patagonicus, which are described in Scientific Reports.
To make shapeshifting of materials possible for a number of different uses, researchers used the anglepoise lamp as inspiration to create material made of interlocking blocks that can be manipulated into any shape, according to a study in Proceedings of the National Academy of Sciences. In another study, in Physical Review Letters, physicists were able to change a liquid crystal's flat surface by introducing a bumpy surface nearby, without using any kind of outside stimulus.
The NIH has awarded Johns Hopkins Medicine a grant of close to $4 million to study the health affects of psilocybin to treat people addicted to tobacco. Johns Hopkins researchers will work alongside teams from the University of Alabama at Birmingham and New York University on the project.
Automotive students at a Kansas high school received a donated Ford Focus to work on. Lori Schmitt, an automotive teacher, says students will learn to repair real-world "bugs in the vehicle" that might happen when people drive their cars.
A tiny, well-preserved crab that dates back roughly 100 million years to the time of dinosaurs has been found encased in amber with all its features visible. "The specimen is spectacular, it is one of a kind. It's absolutely complete and is not missing a single hair on the body, which is remarkable," said Javier Luque, lead author of the study on the find in Science Advances.
The City of Frankfort, Ky., donated a previously used ambulance to the Franklin County Career and Technical Center for students in the EMT program to practice on. The EMT program started three years ago, and the number of students rose from four last year to 12 this year.
