High-school students at an Oklahoma school recently built a walking bridge that connects the school's parking lot to the building. The existing bridge was more than 20 years old and the district was concerned about its safety.
Nearly 25% of the ice sheet in West Antarctica is now thought to be unstable, according to an examination of satellite data published in Geophysical Research Letters. "Using this unique dataset, we've been able to identify the parts of Antarctica that are undergoing rapid, sustained thinning -- regions that are changing faster than we would expect due to normal weather patterns," said researcher Malcolm McMillan.
A Virginia metal fabrication and industrial maintenance firm is offering career and technical scholarships to area high-school graduates. The scholarships are open to students studying to work in fields such as carpentry, electrical, HVAC and machining.
Welding students at a Texas high school recently built a custom, mobile hunting blind trailer that will make it possible for a military veteran who is disabled to hunt. The structure was designed to accommodate the veteran's wheelchair.
Students at an Arizona high school are learning to design and build through a precision manufacturing course. The career-focused course has expanded enrollment from about 40 students when it first launched to 282 today.
Okaloosa Technical College HVAC instructor Billy Mosteferis is using a $500 grant from WEAR and Hill-Kelly Dodge Chrysler Jeep Ram's "Pay it Forward to Education" promotion to buy service wrenches for students who complete 500 hours of their first program. Students from the college should not have trouble finding work -- Mosteferis said he gets requests for employees twice a week or more.
DNA in pitch from pieces of birch bark that were chewed like modern chewing gum and date back approximately 10,000 years is helping researchers learn about the movements of ancient Scandinavians. The DNA found by the scientists, which contains information about three people, is the oldest DNA found in that area of the world, according to findings published in Communications Biology.
The universe may not be as old as once thought, a study to be published in The Astrophysical Journal suggests. Some researchers have pegged the age of the universe at between 12.5 billion and 13 billion years old rather than 13.8 billion, and "the discrepancy suggests that there's something in the cosmological model that we're not understanding right," says study co-author Adam Riess.
B cells in mice have been modified with CRISPR-Cas9 to make them express antibodies against respiratory syncytial virus, a study published in Science Immunology says. Scientists hope their research can lead to vaccines for such difficult-to-treat viruses as RSV, flu, Epstein-Barr virus and HIV.
