Bioengineers and cognitive scientists have developed the first portable, 64-channel wearable brain activity monitoring system that's comparable to state-of-the-art equipment found in research laboratories.
Scientists have discovered that a metabolic pathway previously only suggested to be functional in photosynthetic organisms is actually a major pathway and can enable efficient conversion of carbon dioxide to organic compounds.
Biophysicists have developed a hypothesis to explain the function of a light-driven protein which pumps sodium ions across a cell membrane, and they have revealed the key structural feature of these pumps. The scientists see these sodium pumps as being highly promising tools in using light signals to control nerve cells - which is exactly what is involved in the new scientific field of optogenetics.
Thanks to a new method for making interspecies yeast hybrids in the lab, the makers of beer, wine, biofuels and other products that depend on yeasts may soon have many more strains of the microorganism to work with.
Chemical engineers and neuroscientists have developed a new way to classify neurons by labeling and imaging the proteins found in each cell. This type of imaging offers clues to each neuron's function and should help in mapping the human brain, the researchers say.
Researchers have developed a method to efficiently turn human stem cells into retinal ganglion cells, the type of nerve cells located within the retina that transmit visual signals from the eye to the brain. Death and dysfunction of these cells cause vision loss in conditions like glaucoma and multiple sclerosis.
