Color vision, ocular color detection is achieved with complicated neural mechanisms in the eyes. Researchers from the Osaka City University in Japan have found color detection with a simplest mechanism in the fish pineal organ, an extraocular photosensitive organ on the brain surface.
Japanese researchers developed a system that can automatically image single molecules within living cells. This system employs learning via neural networks to focus appropriately on samples, search automatically for cells, image fluorescently labeled single molecules, and track their movements. With this system, the team achieved the automated determination of pharmacological parameters and quantitative characterization of the effects of ligands and inhibitors on a target, which has potentially profound implications for biological and medical sciences.
Watching the movement of every cell in an adult animal all at once, the Prakash lab discovered ultra-fast cellular contractions. This research suggests a new role for cellular contractions in tissue cohesion, which could be the basis of a new material.
Discoveries about the neurological processes by which flies stay steady in flight by researchers at Case Western Reserve University could help humans build more responsive drones or better-balanced robots.
Inspired by the visual system of the mantis shrimp-researchers have created a new type of camera that could greatly improve the ability of cars to spot hazards in challenging imaging conditions.
How the light-sensitive part of the biomolecule phytochrome changes from a light-adapted state to a dark-adapted state has been investigated by researchers at Ruhr-Universität Bochum and Philipps-Universität Marburg. So far, the structures of only a few light-sensitive biomolecules are known -- and only for the final states in light and darkness, but not for the intermediate steps. Using various spectroscopic methods, the Bochum-Marburg team has now succeeded in gaining new insights into dynamic structural changes.
Published today in The Journal of Experimental Biology, a UC Riverside-led research team shows that mouth injuries caused by hook removal after catch-and-release fishing hamper the ability of fish to capture prey. The results add to a growing body of literature raising questions about the practice of catch-and release fishing, which is viewed by many as a way to conserve at-risk fish species.
Northwestern University and Washington University School of Medicine researchers have developed the first example of a bioelectronic medicine: an implantable, biodegradable wireless device that speeds nerve regeneration and improves healing of a damaged nerve. Their device delivered pulses of electricity to damaged nerves in rats after a surgical repair process, accelerating the regrowth of nerves and enhancing the recovery of muscle strength and control. The device is the size of a dime and the thickness of a sheet of paper.
Lab-on-a-chip devices harness electrical signals to measure glucose, tell apart blood type and detect viruses or cancer. But biological samples need hafnium oxide for protection from the electric fields.
Researchers at Tokyo University of Agriculture and Technology (TUAT) have developed a simple technique that allows detection of two independent microRNAs as an early diagnosis marker of Small Cell Lung Cancer (SCLC) , which is very aggressive. In this technique, they combined nanopore and DNA computing technologies as rapid and label-free detection. This method, therefore, could help to identify SCLC in the early stage.
