Agriculture students at an Iowa high school recently assisted in the construction of a bioretention cell on their campus. The green infrastructure project, in collaboration with the Department of Agriculture In Land Stewardship, was aimed at improving stormwater management on the campus.
Poison dart frogs with yellow stripes are more effective at fending off bird attacks, but those with white stripes have developed ways to enhance their survivability, say researchers in the Proceedings of the National Academy of Science. The frogs with white stripes appear to have changed their behavior to be more evasive than those with yellow stripes, say the researchers.
Images of dunes on Mars have been captured by the European Space Agency's ESA-Roscosmos ExoMars Trace Gas Orbiter's Colour and Stereo Surface Imaging System. The dunes look like ribbons of white shot through with dark patches, which are caused when gas mixed with sand bursts from cracks in the thin layer of carbon dioxide ice covering the dunes during springtime defrosting, researchers say.
Vikings likely hunted a subspecies of walrus to extinction in Iceland about 700 years ago, according to findings published in Molecular Biology and Evolution. Researchers say they suspect the walruses were hunted for their ivory tusks, which were highly valued during that time period.
The University of Wisconsin-Madison has received a $1.8 million grant from the Foundation for Food and Agriculture Research and the Crops of the Future Collaborative to study genes in corn linked to drought tolerance. "I am pleased that we can contribute our expertise in corn genetics to understand the fundamental biological mechanisms that make the plant more resilient," said the university's Kate VandenBosch.
National Science and Technology Council chairman Kelvin Droegemeier has released an open letter to US scientists, outlining the council's plans to bolster the government's policies regarding research security, and he's embarking on a nationwide listening tour of universities to gather feedback directly from scientists. "This is an opportunity to reaffirm the fundamental principles of research, which requires ethical behavior, honesty and integrity," he wrote.
State and local leaders in California recently toured career and technical education programs in the Merced Unified district, including what is believed to be the largest high-school agriculture education program in the nation. Superintendent Alan Peterson says the programs help to prepare students for college and career.
Officials in a Colorado district are preparing to open a new Career and Technical Education Center. Officials recently discussed courses to offer at the new center, including in the fields of construction and skilled trades, advanced manufacturing, computer science, health care and automotive repair.
Students at an Indiana career center are preparing for future careers through the center's welding program. Students learn about several aspects of welding, including shielded metal, gas metal arc and oxy-fuel and learn to work with materials flat, vertical, horizontal and overhead.
Students enrolled in an agriculture mechanics course at an Illinois high school are among those who will get hands-on experience working on about 40 donated engines -- worth about $23,000. The John Deere equipment, officials say, will be put to good use at a number of schools, training students to work on two-cylinder, diesel, tractor or combine engines.
