Asteroid impact sulfur release less lethal in dinosaur extinction

Sciencedaily.com 

Previous studies have posited that the mass extinction that wiped the dinosaurs off the face of the Earth was caused by the release of large volumes of sulfur from rocks within the Chicxulub impact crater 66 million years ago. A new study questions this scenario. Using groundbreaking empirical measurements of sulfur within the related Cretaceous-Paleogene (K-Pg) boundary layer, the international team has demonstrated that the role of sulfur during the extinction has been overestimated.

Thin lenses have a bright future

Sciencedaily.com 

Paper-thin optical lenses simple enough to mass produce like microchips could enable a new generation of compact optical devices. Researchers have fabricated and tested flat lenses called Fresnel zone plates (FZPs), but did so for the first time using only common semiconductor manufacturing equipment, the i-line stepper, for the first time. These flat lenses currently lack the efficiency of in-production lenses, but have the potential to reshape optics for industries ranging from astronomy to health care and consumer electronics.

Biochar reduces the risks of DDT-contaminated soil

Sciencedaily.com 

DDT soil pollution is still a major problem in many parts of the world. Researchers have developed a new method to manage ecological risks from the toxin by binding it with biochar. When they mixed biochar into contaminated soil at a former tree nursery, DDT uptake by earthworms in the soil was halved. This method may enable the growing of certain crops on land that is currently considered unusable due to the environmental risks.
