| More fresh air in classrooms means fewer absences  | If you suspect that opening windows to let in fresh air might be good for you, a new study has confirmed your hunch. Analyzing extensive data on ventilation rates collected from more than 150 classrooms in California over two years, the researchers found that bringing classroom ventilation rates up to the state-mandated standard may reduce student absences due to illness by approximately 3.4 percent. | Read More »  U.S. Clean Air Act increased Atlanta rainfall  | The Clean Air Act of 1970 caused a rebound in rainfall for a US city. Scientists analyzed summer rainfall data from nine weather stations in the Atlanta metropolitan area from 1948 to 2009. They discovered that precipitation increased markedly in the late 1970s as pollution decreased following passage of the Clean Air Act of 1970. | Read More » Formula-feeding linked to metabolic stress and increased risk of later disease  | New evidence from research suggests that infants fed formula, rather than breast milk, experience metabolic stress that could play a part in the long-recognized link between formula-feeding and an increased risk of obesity, type 2 diabetes and other conditions in adult life. | Read More » Increased NMR/MRI sensitivity through hyperpolarization of nuclei in diamond  | Researchers have demonstrated the first magnetically-controlled nearly complete hyperpolarization of the spins of carbon-13 nuclei located near synthetic defects in diamond crystals. This spin hyperpolarization, which can be carried out with refrigerator-style magnets at room temperature, enhances NMR/MRI sensitivity by many orders of magnitude. | Read More » Scientists map the wiring of the biological clock  | Biologists have discovered a crucial part of the biological clock: the wiring that sets its accuracy to within a few minutes out of the 1440 minutes per day. This wiring uses the neurotransmitter, GABA, to connect the individual cells of the biological clock in a fast network that changes strength with time of day. | Read More » New scorpion species adds to the remarkable biodiversity of the Ecuadorian Andes  | A new large-tail scorpion species has been discovered in the Ecuadorian Andes. The 5 cm long, reddish brown Tityus (Atreus) crassicauda could be only a tiny part of an avalanche of future discoveries in the region, considered by many as the "epicenter" of global diversity. | Read More » Stars don't obliterate their planets (very often)  | Stars have an alluring pull on planets, especially those in a class called hot Jupiters, which are gas giants that form farther from their stars before migrating inward and heating up. Now, a new study using data from NASA's Kepler Space Telescope shows that hot Jupiters, despite their close-in orbits, are not regularly consumed by their stars. Instead, the planets remain in fairly stable orbits for billions of years, until the day comes when they may ultimately get eaten. | Read More » | |
