A Minnesota school district has expanded STEM teaching strategies -- problem solving, critical thinking and inquiry-based learning -- to all three of its elementary schools. The district has a three-year professional development plan to incorporate the instructional style that includes staff development meetings and guidance from teacher leaders.
High-school students competed in teams during the recent Tiny Home Build-A-Thon, as part of the 37th Annual Southern Oregon Home Show. The students volunteered their time on the project, which will provide houses to people who are homeless.
A massive stream of stars that formed as a cluster in our galaxy about a billion years ago has been discovered moving through the Milky Way, according to data from the European Space Agency spacecraft Gaia. "Astronomers have been looking at, and through, this new stream for a long time, as it covers most of the night sky, but only now realize it is there, and it is huge, and shockingly close to the sun," says Joao Alves, an author of a study published in Astronomy & Astrophysics.
A Nebraska high school is offering juniors and seniors the opportunity to take free college courses in nine career pathways, including business, health and manufacturing. The program is intended to help students prepare for potential careers locally.
Eight students from two high schools in Maryland recently worked to build three different custom bicycles for children with special needs. The effort was part of Northrop Grumman's engineering week and included support from Volunteers for Medical Engineering.
A high school in Kansas launched an agricultural pathway program this school year that includes an introduction to agriculture, animal science, veterinary science and agribusiness. In one project, students will incubate chicken eggs for a contact in the poultry industry.
If a lake does exist beneath the ice in Mars' south pole, a chamber of magma would need to underlie it to keep the lake liquid, a study published in Geophysical Research Letters suggests. "We tried to do our due diligence and think of all sorts of alternative factors that could raise the temperature," said planetary scientist Michael Sori, noting a discarded theory regarding dust mixed into the ice cap to improve its insulating capabilities.
Early humans hunted small game such as monkeys and squirrels about 45,000 years ago in the rainforests of what is now Sri Lanka, according to findings published in Nature Communications. Researchers examined tooth and bone fragments, which may have been used as cutting and stabbing tools, to learn how humans adapted to the challenging environment.
Amateur archaeologists known as mudlarkers found a Neolithic skull fragment as they searched for artifacts along England's Thames River. The skull dates back 5,600 years and likely belonged to a farmer, a Museum of London curator says.
The National Institute of Allergy and Infectious Diseases has awarded a $3.34 million grant to Case Western Reserve University pharmacology professor Edward Yu, who is studying antibiotic-resistant bacteria. Yu is looking specifically at B. multivorans, which can cause serious infections in people with compromised immune systems along with lung disease.
