Scientists identify new catalytic process to create pharmaceuticals with less chemical waste

Much like two children in the back seat of a car, it can be challenging to get two catalysts to cooperate for the greater good. Now Northwestern University chemists have gotten two catalysts to work together on the same task -- something easily done by nature but a difficult thing to do in the laboratory.The findings, published by the journal Nature Chemistry, will allow medicinal chemists to invent new reactions and produce valuable bioactive compounds faster with less impact on the environment.

Scientists develop carbon based nanoscale to detect single DNA molecules

Researchers at the University of Pennsylvania have developed a new, carbon-based nanoscale platform to electrically detect single DNA molecules.Using electric fields, the tiny DNA strands are pushed through nanoscale-sized, atomically thin pores in a graphene nanopore platform that ultimately may be important for fast electronic sequencing of the four chemical bases of DNA based on their unique electrical signature.The pores, burned into graphene membranes using electron beam technology, provide Penn physicists with electronic measurements of the translocation of DNA.

Scientists discover repair mechanism of photolyase in sun damaged DNA

Researchers have long known that humans lack a key enzyme one possessed by most of the animal kingdom and even plants that reverses severe sun damage.For the first time, researchers have witnessed how this enzyme works at the atomic level to repair sun-damaged DNA.The discovery holds promise for future sunburn remedies and skin cancer prevention.

Replacing hydrogen with deuterium increases stability, shelf life of fluorescent probes: Research

By swapping out one specific hydrogen atom for an isotope twice as heavy, researchers have increased the shelf life and detection ability of fluorescent probes that are essential to studying a variety of inflammatory diseases, including cancer and atherosclerosis. The probes detect and measure reactive oxygen species, which play an important role in disease processes.
