Researchers attached tiny video cameras with microphones to gentoo penguins in Antarctica to better understand their behaviors and calls, per a study published in Nature. One call resulted in the rapid gathering of a group of penguins that then dove underwater, and researchers hope to learn more about the calls and behaviors by attaching cameras to more penguins in the same group.
The clay used to create the 2,200-year-old terra-cotta army in China is providing insights into how the statues were created, according to findings published in Antiquity. The clay pastes prepared in three forms were mixed at one location, then passed to special workshops where the figures were actually constructed using clay recipes with unique signatures.
Cyanobacteria can surround a green laser beam in murky seawater and carry its light farther than expected, a study published in Physical Review Letters suggests. The Synechococcus cyanobacteria create a fiber around the beam, acting as a waveguide and allowing the light to travel a bit farther, researchers say.
Unique sugars called oligosaccharides help some women's breast milk kill dangerous bacteria, according to findings presented at the American Chemical Society's annual meeting. Researchers applied oligosaccharides from breast milk of five women to group B strep cultures, and one sample killed the strep colony, while the others showed varying degrees of bacteria-fighting ability.
The NIH has awarded a $2.2 million grant to the University of Alabama at Birmingham's Translational Research for Injury Prevention Laboratory to study distracted driving by teenagers. "What we need to know more about is the relationship between young age and low driving experience to driving attention," says the university's Despina Stavrinos, who is leading the research.
Biotech firm Exscien, based in Louisville, Ky., has been awarded a $3.7 million grant from the National Heart, Lung, and Blood Institute to develop heart failure treatments. The study will focus on how a proprietary protein affects heart disease.
Roane State Community College in Tennessee partnered recently with Verizon Innovative Learning to hold a summer camp for middle-school girls. The camp provided hands-on experiences in science, technology, engineering and math, including lessons on coding, 3D design and entrepreneurship.
An Oklahoma high school's internship program provides students with hands-on experiences and helps prepare them for college and career. The school connects senior students with local organizations for internships that count as credit in a student's elective coursework.
Students at two schools in Austin, Texas, will be able to earn associate degrees in cybersecurity and computer science or health science while in high school. Through the Career Launch program, students will be matched with professional mentors.
