Students at a Connecticut high school are preparing for careers in manufacturing through a statewide pilot program. Manufacturing teacher Eric Soucie says students learned the basics, including safety practices, and then completed their first project -- constructing simple shop tools.
Sun bears communicate by mimicking each other's facial expressions, a practice long thought to occur only in species with complex social systems, a study published in Scientific Reports suggests. "Other primates and dogs are known to mimic each other, but only great apes and humans were previously known to show such complexity in their facial mimicry," said study co-author Marina Davila-Ross.
Construction students at a Georgia high school recently learned about the trade firsthand during a visit to the building site of a new emergency department addition at a nearby medical center. The goal was to demonstrate a potential career path for students.
Students at 12 high schools in Hawaii are learning about careers in the restaurant industry through the Hawaii ProStart curriculum. Students who participate are encouraged to seek internships in restaurants, as well as earn industry certifications.
Seventh-graders at a Wisconsin school toured two local businesses as part of a career exploration event organized by the school district, local chamber of commerce and Junior Achievement. One group of students received a tour of a bank and then went to a medical office, where they viewed splinting and ultrasound machines and tried suturing pigs' feet.
Genetic databases aren't ethnically diverse, with most participants in genome-wide association studies being of European descent, according to a commentary published in Cell. The NIH All of Us program and private DNA database companies such as 23andMe are working to diversify the data available by increasing the number of participants from underrepresented groups.
Chinese researchers have uncovered more than 4,300 well-preserved fossils at a site along the Danshui River in China that dates back 518 million years. The fossils include many organisms never seen before, according to findings published in Science.
A healthy baby monkey has been born using sperm developed from frozen immature testicular tissue in a procedure that may one day help prepubescent boys whose future fertility is compromised by cancer treatments, according to findings published in Science. Researchers removed testicular tissue from rhesus macaques that hadn't yet reached sexual maturity, froze it and then grafted it back when the monkeys had matured, resulting in viable sperm recovered up to 12 months later.
An abundance of carbon monoxide in an exoplanet's atmosphere could indicate the presence of life, much like there was on Earth 3 billion years ago, when there wasn't much oxygen but microbial life thrived, according to a study published in The Astrophysical Journal. "Given the different astrophysical context for these planets, we should not be surprised to find microbial biospheres promoting high levels of carbon monoxide," said Edward Schwieterman, the study's lead author.
