The 2011 Bonn Challenge is securing national commitments to restore hundreds of thousands of square miles of tropical forests globally, an encouraging development, write Matthew Fagan, Leighton Reid and Margaret Buck Holland. However, a closer look reveals that "some reforestation efforts provide only limited benefits, and studies have shown that maintaining these forests for decades is critical to maximize the economic and ecological benefits of establishing them."
Air New Zealand will test ST Engineering's drone system to inspect aircraft at its maintenance facility in Singapore. The system is designed to fly around the aircraft to produce images that are processed with algorithms that detect and classify defects.
Preventive maintenance tasks should not be pushed aside by "emergency" work, writes Glyn Thorman, and if a scheduled job does not seem important enough to compete for precedence, the maintenance schedule should be re-examined. "The bottom line," he says, "is that if the PM control process says to do a PM monthly, either do it monthly or change the process" instead of trying to convince a supervisor that it wasn't necessary.
Lightyear says the photovoltaic cells on its prototype One EV car add as much as 12,500 miles annually to its range, which comes to a claimed 450 miles per charge. The company credits the performance to a smallish battery that's more easily recharged by the PV cells, which can also be recharged quickly from any power outlet.
First-generation college student and Society of Hispanic Professional Engineers member Crysthal Alvarez served as the student commencement speaker at this month's commencement ceremony for the University of California at Riverside's Marlan and Rosemary Bourns College of Engineering. Alvarez received a Top Honors Award at the UC LEADS Research Symposium for her transparent cranial implant research and served as external outreach chair for the school's SHPE chapter.
NASA Solar System Ambassador and biologist Elizabeth Garcia helps promote STEM education in the Ukiah, Calif., area through events such as Bounce to the Stars and school field trips. In her work, Garcia said she hopes "to inspire the next generation of scientists and engineers and curiosity seekers, and hopefully future mission specialists."
Los Angeles is leading the nation in STEM job growth, with an increase of 8.2% in available jobs from 2014 to 2018, according to CBRE data. Seattle is second in the same category, climbing 8.1% during the period.
Growing global food and non-food commodity demand is negatively affecting primate populations and could lead to their extinction, according to a study. The study's authors recommend changing consumer habits and the establishment of an international environmental improvement fund to aid forests.
A study by University of Illinois researchers indicates that phenolic compounds in cocoa bean shells have strong effects on the fat and immune cells of mice, which could lead to solutions for the chronic inflammation and insulin resistance found alongside obesity. "The objectives of the study were to test whether the bioactive compounds in the cocoa shells were efficacious against macrophages - the inflammatory cells - at eliminating or reducing the biomarkers of inflammation," professor Elvira Gonzalez de Mejia explained.
A study from the National Academy of Sciences found 43% of women and 23% of men leave full-time work in science, technology, engineering and math fields when they become parents. Businesses can help offset child care costs or provide on-site care to keep parents working.
