Dual-Layer Solar Cell Sets Record for Efficiently Generating Power
A solar cell developed by UCLA Engineering researchers converts 22.4 percent of incoming energy from the sun, a record for this type of cell.
A new way to remove ice buildup without power or chemicals
From airplane wings to overhead powerlines to the giant blades of wind turbines, a buildup of ice can cause problems ranging from impaired performance all the way to catastrophic failure. But preventing that buildup usually requires energy-intensive heating systems or chemical sprays that are environmentally harmful. Now, MIT researchers have developed a completely passive, solar-powered way of combating ice buildup.
Prehistoric Vegetation Helps Predict Future Ecosystems
An international research team found that planet warming drove major changes in vegetation and future warming may drive similarly dramatic changes around the world.
Genetics and pollution drive severity of asthma symptoms
Asthma patients, with a specific genetic profile, exhibit more intense symptoms following exposure to traffic pollution, according to researchers at the National Institutes of Health and collaborators. The study appeared online in Scientific Reports.
Most Land-Based Ecosystems Worldwide Risk ‘Major Transformation’ Due to Climate Change
Researchers compiled and evaluated pollen and plant-fossil records from nearly 600 sites worldwide for their study of vegetation change.
