The destructive wildfires in Australia during 2019 and 2020 had wide-ranging effects, according to a pair of studies in Nature. One study suggests that the fires released substantially more carbon dioxide than scientists originally estimated, while the other found that the ash fed huge blooms of phytoplankton that captured large amounts of the CO2.
An Ohio school district has converted its solar array space to become the home of the Northwest Scioto County Career and Technical Center FFA chapter's first sheep flock and on-school farm. The flock supports vegetation management and is used in animal science classes.
An average of 4.9 million metric tons of carbon dioxide equivalent is being released annually in New England and New York as a result of forest loss in the region, according to a new study. The impact is greater when accounting for lost capacity for carbon sequestration. Clark University geography professor Christopher Williams was lead author for the study, which involved reviewing satellite images and field plots from the US Forest Service.
Forecasting the extent of Arctic sea ice is getting a boost from artificial intelligence in a process detailed in Nature Communications. IceNet, created by the British Antarctic Survey, can forecast the amount of sea ice two months ahead with about 95% accuracy, much more quickly than the current leading method, researchers say.
NASA has extended Mark Vande Hei's International Space Station mission to next March, which will give him 353 days on the research spacecraft, breaking the 340-day record for an American astronaut currently held by Scott Kelly. Vande Hei says the experience will help scientists learn more about how long-term spaceflight affects the human body.
A mother spider protecting her egg sac roughly 99 million years ago became trapped in amber and is among amber finds from that time period described in Proceedings of the Royal Society B: Biological Sciences. Another amber piece holds just-hatched Lagonomegopidae spiders, which are now extinct, with a leg fragment from their mother, and researchers say these discoveries indicate how the creatures cared for their young.
Sixth-graders in New Mexico's Las Cruces Public Schools recently participated in a Mars mission simulation, including a mock shuttle flight, at the Challenger Learning Center. The field trip to the center, which has reopened following a pandemic-related closure, offered a hands-on experience with science, said teacher Luis Torres.
The Career Ready Practices Training program in North Dakota this month will help to train teachers to support students' career pathways. The move, to help teachers measure students' abilities in five soft skills, comes amid a shortage of workers in the skilled trades.
Manufacturing output grew 0.2% in August, less than expected due to the effects of Hurricane Ida, and total industrial production rose 0.4%, the Federal Reserve reports. Other data shows that manufacturers are facing high prices for processed goods for intermediate demand and a record number of job vacancies.
An $11.5 million NIH grant will allow scientists at Arkansas Children's Research Institute and the University of Arkansas for Medical Sciences to better understand the causes and implications of obesity in childhood. "Our goal is a future where parents don't have to worry about their child developing any of the countless complications children face because of obesity," said principal investigator Judith Weber.
