Researchers quantify Cas9-caused off-target mutagenesis in mice Posted: 19 Oct 2019 12:40 PM PDT Scientists are finding new ways to improve the use of the CRISPR enzyme Cas9 and reduce the chances of off-target mutations in laboratory mice, according to new results. The findings will help scientists contextualize a common concern related to gene editing and identify new strategies to improve its precision. |
Novel nanoprobes show promise for optical monitoring of neural activity Posted: 18 Oct 2019 03:10 PM PDT Researchers have developed ultrasensitive nanoscale optical probes to monitor the bioelectric activity of neurons and other excitable cells. This novel readout technology could enable scientists to study how neural circuits function at an unprecedented scale by monitoring large numbers of individual neurons simultaneously. It could also lead to high-bandwidth brain-machine interfaces with dramatically enhanced precision and functionality. |
'Flamenco dancing' molecule could lead to better-protecting sunscreen Posted: 18 Oct 2019 05:06 AM PDT A molecule that protects plants from overexposure to harmful sunlight thanks to its flamenco-style twist could form the basis for a new longer-lasting sunscreen, chemists have found. |
Posted: 18 Oct 2019 05:06 AM PDT It is crucial for photovoltaics and other technical applications, how efficiently energy spreads in a small volume. With new methods, the path of energy in the nanometer range can now be followed precisely. |
Scientists recalculate the optimum binding energy for heterogeneous catalysis Posted: 17 Oct 2019 06:15 PM PDT In a discovery that could lead to the development of novel catalysts that do not rely on expensive rare metals, scientists have shown that the optimal binding energy can deviate from traditional calculations, which are based on equilibrium thermodynamics, at high reaction rates. This means that reconsidering the design of catalysts using the new calculations may be necessary to achieve the best rates. |
