Automotive students at an Iowa high school are working on vehicles owned by area nonprofit organizations. The work, performed for free, includes diagnostic scans, tire rotations, oil changes and other maintenance.
Scientists were surprised to find that juvenile tiger sharks dine on land-based birds fairly regularly, possibly because of the birds' migration patterns, a study published in Ecology suggests. Birds showing up in the tiger sharks' bellies included brown thrashers, marsh wrens and swamp sparrows.
An Ohio high school recently started an integrated production technologies course as part of its plan to prepare students for college, career or the armed forces. Plans call for expanding the program to include internships with area manufacturers.
A school district in Texas recently held a "Hiring Day" event to introduce students who are not enrolling in college to potential career paths. The business community -- particularly manufacturers -- also encouraged the event, saying they were struggling to find qualified employees.
Warming global temperatures may result in a sea level rise of more than two meters by 2100 if nothing is done to control carbon emissions, a study published in the Proceedings of the National Academy of Sciences suggests. A sea level increase of that magnitude could displace nearly 200 million people as flooding affects such major cities as New York, Miami, Shanghai and Mumbai.
The majority of Anthropocene Working Group members voted to designate the Anthropocene as a new geological epoch, one that is marked by the influence of human activity and that started sometime in the mid-20th century. After the working group makes a formal proposal, the epoch will still have to be considered by other groups in the International Commission on Stratigraphy and the International Union of Geological Sciences.
Genetically engineered fruit flies were used to screen a customized combination of cancer drugs before it was given to a terminally ill patient with colon cancer, according to a study published in Science Advances. The screened drugs helped shrink the patient's tumors significantly, and researchers say the method may lead to more effective treatments.
Fossils of fungus found in the Canadian Arctic may be the oldest ever found on Earth, dating back up to a billion years, according to findings published in Nature. The fungi's advanced age is about 500 million years older than the previous fungus record-holder.
A sauropod that lived about 200 million years ago started life on four legs but eventually grew to walk on two in adulthood, according to findings published in Scientific Reports. Researchers used computer simulations to observe how the creature's center of gravity moved over its lifetime to allow it to become bipedal.
The Puyallup Tribe of Indians is funding the first year of a partnership with Washington State University that aims to establish treatment plan standards and evaluate the use of medicinal cannabis as an opioid alternative. Attempts to procure federal funding for such research have been complicated by legal constraints.
