Higher temperatures can exacerbate century-to-century climate variability, a study has found. Researchers reviewed data from the last interglacial period, from 130,000 to 115,000 years ago, to reach their conclusions.
A group of fifth- and sixth-graders recently learned about environmental science and watershed pollution through a hands-on project to build a rain garden at their school in Connecticut. Students used water-tolerant plants, peat moss and mulch to capture and filter rainwater run-off from a roof and parking lot before it drained into other waterways on the way to Long Island Sound.
The destructive eruption of Mount Vesuvius, long thought to have occurred on Aug. 24 in A.D. 79, may actually have happened almost two months later, according to an inscription found by archaeologists in Italy. The charcoal inscription, referring to the 16th day before the "calends" of November, equating to Oct. 17 on the modern calendar, was written on remains in Pompeii recently excavated by researchers.
A study using spatial awareness tasks and math problems found no evidence for "the stereotype threat," in which a woman's performance might be affected when she is aware of negative stereotypes -- such as the idea that women are bad at math. "This study -- and other emerging research -- therefore calls into question how well the theory of stereotype threat can explain gender differences in mathematical performance," said the study's author, Charlotte Pennington, from the University of the West of England.
A Kentucky high school recently constructed an "Innovation Zone" that will house the school's expanding computer-aided design and engineering program. Innovation Zone instructor Carl Owens says the courses prepare students for jobs in the skilled trades through hands-on learning.
Students at the Community College of Philadelphia will more easily be able to enroll in Rutgers University-Camden under a dual-admission agreement expected to be signed this week. Under the agreement, students who earn an associate degree and meet certain requirements will be able to enroll in the four-year university as juniors.
Scientists will debate the merits of four potential landing sites for NASA's Mars 2020 rover during a three-day workshop this week before recommending where the rover will land and collect samples that may end up being the first brought back to Earth. The sites under consideration are Columbia Hills, Jezero Crater, Northeast Syrtis and Midway.
Generations of male mice exhibited learning and behavioral problems linked to nicotine exposure in their fathers and grandfathers, according to findings published in PLOS Biology. "Our study shows that paternal nicotine exposure can be deleterious for the offspring in multiple generations," said study leader Pradeep Bhide.
Arthropod populations in Puerto Rico's Luquillo rainforest have declined sharply, and warmer temperatures may be the cause, according to findings published in Proceedings of the National Academy of Sciences. Researchers first collected information on arthropods in the rainforest in 1976 and compared it to data collected in 2012, finding a decline of up to 99%, while temperatures recorded during the period climbed by 2 degrees Celsius, or 3.6 degrees Fahrenheit.
Billionaire Stephen Schwarzman has donated $350 million to MIT for its planned College of Computing. The $1 billion interdisciplinary college will focus on artificial intelligence research across non-technology fields.
