High-school welding students in New York state designed and built a metal bike rack that they donated to their local parks department. Students built the bike rack at the SkillsUSA New York State competition held earlier this year.
Research suggests that nearly half of the world's population will be exposed to deadly heat waves by 2100, even if efforts are made to curb climate change. The study, led by geography professor Camilo Mora of the University of Hawaii at Manoa, found that nearly three-quarters of the population could be exposed to these heat waves if emissions continue to increase at the current pace.
A "disturbance map" from the recently launched Silent Forest project highlights degraded areas of the Amazon where tree density has thinned and biodiversity is at risk. "The data visualization from scientific studies is an important step in the struggle for forest conservation," said Thiago Medaglia, coordinator of the Silent Forest platform.
The Amazon River basin may have been submerged in ocean water at least twice millions of years ago, and that flooding may have contributed to the vast diversity in the area's ecosystem, according to an analysis of sediment cores published in Science Advances. Researchers suggest the Amazon region was flooded about 18 million years ago and then again 14 million years ago.
If all goes as planned, NASA's proposed Europa Clipper mission will fly by Jupiter's moon up to 45 times at various altitudes to study its potential habitability. The mission is supposed to launch by 2022, but that might be pushed back due to budget concerns.
New equipment and technology are making it easier to explore, and eventually mine, the deep-sea floor, long inaccessible but rich in minerals and other resources desired by countries around the world, says University of Southampton Natural and Environmental Sciences Dean Rachel Mills. "The rules for exploitation are yet to be agreed, but contractors will have to demonstrate they have assessed the environmental impact of mining and that plans are in place to manage the effects," she writes.
Viruses that have been genetically modified using the CRISPR-Cas9 gene-editing system have shown promise in defeating antibiotic-resistant bacteria, a presentation at CRISPR 2017 suggests. Several companies are studying bacteriophages and may be ready to start clinical trials next year.
Parkinson's disease could be an autoimmune disorder, which would open up new avenues for treatment, according to findings published in Nature. The study suggests that antigens are displayed by neurons that produce dopamine in Parkinson's patients.
The Max and Minnie Tomerlin Voelcker Fund has provided the University of Texas Health Science Center at San Antonio a total of over $2.3 million for a number of studies focusing on cancer and heart disease. In addition to five individual researchers who received $450,000 each via Young Investigator Awards, the center received $75,000 to study anticancer drugs.
Two high schools in Atlanta are expanding their International Baccalaureate offerings to include the International Baccalaureate Career-related Program. The program, for high-school juniors and seniors, supports career exploration in audio visual technology and film, computer programming, and web and digital design.
