Shedding light on how the human eye perceives brightness Posted: 18 Aug 2019 07:16 AM PDT Scientists are shedding new light on the importance of light-sensing cells in the retina that process visual information. The researchers isolated the functions of melanopsin cells and demonstrated their crucial role in the perception of visual environment. This ushers in a new understanding of the biology of the eye and how visual information is processed. |
Wearable sensors detect what's in your sweat Posted: 16 Aug 2019 04:14 PM PDT A team of scientists is developing wearable skin sensors that can detect what's in your sweat. In a new article, the team describes a sensor design that can be rapidly manufactured using a ''roll-to-roll'' processing technique that essentially prints the sensors onto a sheet of plastic like words on a newspaper. The sensors can provide real-time measurements of sweat rate, and electrolytes and metabolites in sweat. |
Superconductors: Unraveling the stripe order mystery Posted: 16 Aug 2019 04:14 PM PDT Researchers have shed new light on how superconductivity and charge order can exist adjacent to one another. |
Identification of genes responsible for sex-related differences in cancer aggressiveness Posted: 16 Aug 2019 06:24 AM PDT An understanding of the molecular basis of differences in the incidence and survival of cancer between men and women may allow the discovery of specific and more effective treatments. The study compares the brain tumours of male and female flies at the molecular level and identifies proteins responsible for the different degree of aggressiveness. |
Unlocking the nanoscale world on standard biology lab equipment Posted: 16 Aug 2019 04:55 AM PDT Standard optical microscopes can image cells and bacteria but not their nanoscale features which are blurred by a physical effect called diffraction. Now, researchers report a simple way to bypass diffraction limitations using standard optical imaging tools. |
Optofluidic chip with nanopore 'smart gate' developed for single molecule analysis Posted: 16 Aug 2019 04:55 AM PDT A new chip-based platform integrates nanopores and optofluidic technology with a feedback-control circuit to enable an unprecedented level of control over individual molecules and particles on a chip for high-throughput analysis. |
