Caribous are the mammals that migrate the farthest, traveling about 1,352 kilometers, according to findings in Scientific Reports. Coming in second, researchers say, are reindeer, followed, in order, by gray wolves, mule deer and Tibetan antelopes.
Some high-school students in New York state will learn welding skills using virtual reality that simulates real-world welding equipment. Three districts will use the virtual reality welder, which costs $18,500 -- a less expensive and safer option than other equipment -- according to officials.
Charitable efforts are underway to plant trees as part of a push to address climate change, but research suggests that the environmental impact of forested lands can be complex. "We shouldn't see this, or any other nature-based climate change solution, as a silver bullet," said geography professor Christopher Williams, noting that it's critical to reduce the use of fossil fuels.
A beetle found encased in a 99-million-year-old piece of amber along with ancient pollen is helping scientists learn more about the evolution of pollination, according to findings published in Proceedings of the National Academy of Sciences. "[T]his specimen perfectly illustrates the cooperative evolution of plants and animals during this time period, during which a true exposition of flowering plants occurred," says study author David Dilcher.
Examination of proteins taken from a tooth fossil belonging to an ape that lived about 1.9 million years ago suggests a close link between Gigantopithecus blacki and modern orangutans, according to findings published in Nature. "We were surprised to find any proteins this old at all, especially in a fossil from a subtropical environment," says study author Frido Welker.
Students at a Minnesota high school recently learned about careers in manufacturing from five companies and an area community college. The career fair was the first in a series, with other planned events focusing on jobs in construction, transportation and technology.
High-school seniors in Tennessee are part of an inaugural pre-apprenticeship program in the state. The program launched in partnership with schools, a community college and an area company where students will work.
Repurposing old battlefields and other former military spaces can provide benefits to the environment and all who use them, write Todd Lookingbill and Peter Smallwood of the University of Richmond. "[G]iven the scale of threats to natural habitats around the world, conservationists cannot ignore opportunities to cultivate and preserve natural places -- even those that arise from the horrors of war," they write.
Some high-schoolers recently learned about educational and career opportunities in STEM fields -- such as welding, electrical engineering and renewable energy -- at a Monroe, Mich., community college's X-TECH event. The career fair, which spotlights subjects taught at the college, offered students a chance to engage in virtual welding and other hands-on demonstrations.
Data collected by the Curiosity rover show oxygen levels fluctuating seasonally at the Gale Crater by unusual amounts, according to findings published in the Journal of Geophysical Research: Planets. "We're struggling to explain this," said study author Melissa Trainer.
