WASHINGTON (Reuters) – When the fin whale gets ready to eat, Earth’s second-largest animal opens its mouth so wide that it can gulp an amount of water larger than the volume of its own body as it filters out meals of tiny fish and shrimp-like krill.
Scientists at the Southwest Research Institute say they have visually captured the sound waves created by lightning. Lightning strikes Earth an estimated 100 times per second – or more than eight million times a day. The United States alone receives as many as 20 million strikes per year from perhaps 100,000 thunderstorms. Lightning is a [...] —> Read More

Diagnosing a heart attack can require multiple tests using expensive equipment. But not everyone has access to such techniques, especially in remote or low-income areas. Now scientists have developed a simple, thermometer-like device that could help doctors diagnose heart attacks with minimal materials and cost. —> Read More
Conventional silicon-based computing, which has advanced by leaps and bounds in recent decades, is pushing against its practical limits. DNA computing could help take the digital era to the next level. Scientists are now reporting progress toward that goal with the development of a novel DNA-based GPS. —> Read More
NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured these images of a significant solar flare as seen in the bright flash on the left peaking at 6:11 p.m. EDT on May 5, 2015.
A research team has developed an inkjet printing technology to produce kesterite thin film absorbers. Based on the inkjet-printed absorbers, solar cells with total area conversion efficiency of up to 6.4 percent have been achieved. Although this is lower than the efficiency records for this material class, the inkjet printing minimizes waste and has huge advantages for industrial production. —> Read More
