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. |
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. |
Pores for thought: Ion channel study beckons first whole-brain simulation Posted: 15 Aug 2019 05:13 AM PDT Voltage-gated ion channels at the surface of neurons and muscle cells control your every thought, movement; the very beating of your heart. For the first time, researchers have mapped the behavior of the largest family of these channels. Their pioneering work will power virtual drug discovery -- and, they hope, the first whole-brain simulation. |
