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...]

eLife: Geological and taphonomic context for the new hominin species Homo naledi from the Dinaledi Chamber, South Africa

We describe the physical context of the Dinaledi Chamber within the Rising Star cave, South Africa, which contains the fossils of Homo naledi. Approximately 1550 specimens of hominin remains have been recovered from at least 15 individuals, representing a small portion of the total fossil content. Macro-vertebrate fossils are exclusively H. naledi, and occur within clay-rich sediments derived from in situ weathering, and exogenous clay and silt, which entered the chamber through fractures that prevented passage of coarser-grained material.

spiegel online: Geheimnis des Alterns: Was den Grönlandwal 200 Jahre leben lässt

Grönlandwale können über 200 Jahre alt werden und bekommen keinen Krebs. Genanalysen zeigen, was sie so widerstandsfähig macht. Nun hoffen Forscher, dass irgendwann auch der Mensch von den Erkenntnissen profitieren kann. [mehr...]
