Understanding how ice crystals form in clouds
How ice forms on the surfaces of mineral dust particles in the atmosphere has been revealed by a team from the LCN and the Karlsruhe Institute of Technology (KIT) in Germany. More than 90% of precipitation over land relies on the formation of ice crystals on airborne...
Beyond the DNA double helix: From twofold to fourfold DNA
Watson and Crick proposed the DNA double-helix structure over 60 years ago, but DNA is not always arranged in a double helix, also forming other structures. One such structure is fourfold DNA, which is found near DNA-encoded genes that are key in causing cancer. By...
Nano-antennas assist in improving spatial resolution of terahertz microscopy
A team lead by a LCN researcher has demonstrated a detector for terahertz waves with integrated optical nano-antennas. The detector enables enhanced spatial resolution in terahertz microscopy. Similar to more commonly used infra-red waves and X-rays, terahertz waves...
