DNA 'barcodes' help researchers pinpoint gold nanoparticles that can strike cancer at its power source

Living by the sea in the tropics means being exposed to some of nature's most powerful forces. Hurricanes can bring storm surges, flooding and destructive waves that threaten homes, infrastructure and livelihoods.

Until now, it has been technically nearly impossible to rotate highly sensitive samples in all directions under a microscope without making contact. Researchers at the Karlsruhe Institute of Technology (KIT) have developed a new laser-based technique that allows microscopic samples such as cells to be rotated contact-free in all three spatial directions. The laser creates tiny temperature differences in the liquid, which trigger gentle fluid flows that move the sample. This protects delicate sam

Innovators who are working on ways to pull carbon dioxide out of the atmosphere to fight climate change are having a tough time lately.

Throughout history, most of the world's genomic research has relied on DNA data from people of European ancestry.
