The skeletons of two boys, ages 10 and 12, found head-to-head in a 34,000-year-old grave near Vladimir, Russia, were buried with a number of treasures, including mammoth ivory beads, armbands, fox teeth, deer antlers, carved art and ivory mammoth spears, according to findings published online in Antiquity. Also buried at the Sunghir site were several men and women, but their graves were less extravagantly adorned, researchers said.
Scientists have developed a method to determine how 2D thin sheets of materials such as graphene react when heated. The 2D semiconductors are placed in sheets just a single atom thick and behave like plastics when the temperature rises, according to a description of the technique published in Physical Review Letters.
Some genes remain functional and even become more active following an individual's death, and researchers think this could be helpful for forensic science, according to findings published in Nature Communications. "We conclude there is a signature or a fingerprint in the pattern of gene expression after death that could eventually be used in forensic science, but we don't pretend we have now a method that can be used in the field," said study author Roderic Guigo.
There could be a type of universe much different from our own that could support life, according to a study published on arXiv.org. Researchers say this universe could have come together without the weak force, one of the four fundamental forces believed to be necessary for universes to exist.
Beginning in the fall, about 12 students from a New Hampshire school district will earn dual high-school and college credits for a manufacturing course at Great Bay Community College. Students enrolled in the program will work toward earning an Advanced Composite Certificate.
Middle-school students in a Kentucky district recently designed and created shoe soles with the help of high-school mentors during a two-day workshop. The workshop was designed to help engage students in science, technology, engineering and math.
An Iowa community college is helping to start a program designed to address a shortage of manufacturing workers in the area. The 16-week program will teach skills such as taking basic measurements, cutting raw materials and reading blueprints.
In Delaware, more students are choosing to pursue careers as physician assistants instead of doctors. National data show that physician assistants are among the fastest-growing occupations in the US.
A welder and owner of Arnold Quality Metal Works in Logan, Utah, was commissioned to make a rose-themed sculpture ahead of Valentine's Day. Zach Arnold says that being a welder allows him to combine art and science.
