guardian: Genetically engineered 'Magneto' protein remotely controls brain and behaviour

 “Badass” new method uses a magnetised protein to activate brain cells rapidly, reversibly, and non-invasively. Researchers in the United States have developed a new method for controlling the brain circuits associated with complex animal behaviours, using genetic engineering to create a magnetised protein that activates specific groups of nerve cells from a distance. more...

nature: Reversal of biological clock restores vision in old mice

Researchers have restored vision in old mice and in mice with damaged retinal nerves by resetting some of the thousands of chemical marks that accumulate on DNA as cells age. The work, published on 2 December in Nature1, suggests a new approach to reversing age-related decline, by reprogramming some cells to a ‘younger’ state in which they are better able to repair or replace damaged tissue.  more...

NASA at Mars: 20 years of 24/7 exploration


No one under 20 has experienced a day without NASA at Mars. The Pathfinder mission, carrying the Sojourner rover, landed on Mars on July 4, 1997. In the 20 years since Pathfinder's touchdown, eight other NASA landers and orbiters have arrived successfully, and not a day has passed without the United States having at least one active robot on Mars or in orbit around Mars.

the guardian: Rosetta mission ends with touchdown on comet 67P - as it happened




And this seems like a good place to end the coverage today. The final, final images have just been shown. We know that science data was flowing back to Earth from Rosetta until the final moment of touch down. We know that it is going to take years to fully analyse all the data. [more...]

nieman lab: A group of researchers is trying to help science journalists parse academic articles on deadline

The tool is called Science Surveryor, and it’s being developed at Columbia and Stanford to help journalists find context and background information on tight deadlines. [more...]
