A team of scientists led by researchers at UC Santa Barbara has discovered that multiple opsin proteins, known for decades to be required for vision, also function as taste receptors. [36] There are an estimated 20,000 to 30,000 proteins at work in cells, where they carry out numerable functions, says computational molecular biologist Roman Sloutsky at the University of Massachusetts Amherst. [35] Are we alone in the universe? It comes down to whether intelligence is a probable outcome of natural selection, or an improbable fluke. [34] Reconstructing evolutionary branches is tricky, especially when many species share a similar type of protein that might have evolved to perform somewhat different functions. [33] Researchers from the The fight against global antibiotic resistance has taken a major step forward with scientists discovering a concept for fabricating nanomeshes as an effective drug delivery system for antibiotics. [30] The solution consisting of colloidal quantum dots is inkjet-printed, creating active photosensitive layer of the photodetector. [29] I'm part of a group of nanotechnology and neuroscience researchers at the University of Washington investigating how quantum dots behave in the brain. [28] Nanotechnology may provide an effective treatment for Parkinson's disease, a team of researchers suggests. [27] Recent research from Kumamoto University in Japan has revealed that polyoxometalates (POMs), typically used for catalysis, electrochemistry, and photochemistry, may also be used in a technique for analyzing quantum dot (QD) photoluminescence (PL) emission mechanisms.
