Researchers Discover ‘Insulin-Producing’ Viruses

Added: 23.02.2018 12:44 | 5 views | 0 comments

An international team of scientists led by Harvard Medical School’s Joslin Diabetes Center has identified four viruses that can produce insulin-like hormones. Reported in the Proceedings of the National Academy of Sciences, the discovery brings new possibilities for revealing biological mechanisms that may cause disease. By analyzing large research databases that hold viral genomic sequences, [...]

Scientists Develop Nanowiring for Optical Control of Neuron Activation

Added: 23.02.2018 10:30 | 14 views | 0 comments

Researchers have designed silicon nanowires that allow modulation neuronal activity using light, allowing manipulation of specific neural circuits without genetic engineering for the first time. Modern technologies have revolutionized our understanding of the neural basis of human cognition. Nevertheless, fundamental aspects of the brain remain obscure as scientists have been limited in their ability to [...]

In living color: Seeing cells from outside the body with synthetic bioluminescence

Added: 23.02.2018 1:30 | 4 views | 0 comments

Glowing creatures like fireflies and jellyfish are captivating to look at but also a boon for science, as their bioluminescent molecules contribute to visualizing a host of biological processes. Now, scientists have supercharged these molecules, making them hundreds of times brighter in deep tissues and allowing for imaging of cells from outside the body. The bioengineered light source was used to track cancer cells in mice and brain-cell activity in monkeys, but its applications extend beyond the lab.

Loops, loops, and more loops: This is how your DNA gets organized

Added: 23.02.2018 1:30 | 5 views | 0 comments

A living cell is able to neatly package a big jumble of DNA into chromosomes while preparing for cell division. For over a century, scientists have been puzzled for decades on how the process works. Researchers now managed for the first time to isolate and film the process, and witnessed -- in real time -- how a single protein complex called condensin reels in DNA to extrude a loop.

How bats carry viruses without getting sick

Added: 23.02.2018 1:30 | 2 views | 0 comments

Bats are known to harbor highly pathogenic viruses like Ebola or Marburg and yet they do not show clinical signs of disease. Scientists find that in bats, an antiviral immune pathway called the STING-interferon pathway is dampened, and bats can maintain just enough defense against illness without triggering a heightened immune reaction.

A look at the space between mouse brain cells

Added: 23.02.2018 1:30 | 3 views | 0 comments

Between the brain's neurons and glial cells is a critical but understudied structure that's been called neuroscience's final frontier: the extracellular space. With a new imaging paradigm, scientists can now see into and study this complex fluid-filled matrix.
