Geologists at UC Santa Cruz have now taken a close look at the structure and chemistry of glacial polish and […]

Researchers at the University of California, Riverside have developed transgenic mosquitoes that stably express the Cas9 enzyme in their germline. The addition of Cas9 will enable the use of the CRISPR gene editing tool to make efficient, targeted changes to the mosquitoes’ DNA. As proof of concept, the researchers used the system to disrupt cuticle, […]

An asteroid, also known as the Chicxulub Impactor, hit Earth some 66 million years ago, causing a crater 180 km wide. The impact of the asteroid heated organic matter in rocks and ejected it into the atmosphere, forming soot in the stratosphere. Soot is a strong, light-absorbing aerosol that caused global climate changes that triggered […]
