Little-known protein appears to play important role in obesity and metabolic diseaseWith unexpected findings about a protein that's highly expressed in fat tissue, scientists have opened the door to critical new understandings about obesity and metabolism. The discovery could lead to new approaches for addressing obesity and potentially many other diseases.Genetic discovery holds implications for better immunity, longer lifeWrinkles on the skin of a microscopic worm might provide the key to a longer, healthier life for humans. Working with Caenorhabditis elegans, a transparent nematode found in soil, researchers found that the nervous system controls the tiny worm's cuticle, a skin-like exterior barrier, in response to bacterial infections.Highest-energy light from a gamma-ray burst everResearchers have observed a gamma-ray burst with an afterglow that featured the highest energy photons -- a trillion times more energetic than visible light -- ever detected in a burst.The difference between an expert's brain and a novice'sIn learning new tasks, neuron networks in the brain of mice become more refined and selective. Charting changes in neural activity can help inform the design of better computational models for understanding decision making and cognition.Amazon deforestation and number of fires show summer of 2019 not a 'normal' yearThe perceived scale of the Amazon blazes received global attention this summer. However, international concerns raised at the time were countered by the Brazilian Government, which claimed the fire situation in August was 'normal' and 'below the historical average'. A new report finds that the number of active fires in August was actually three times higher than in 2018 and the highest number since 2010.Link between inflammation and mental sluggishness shown in new studyScientists have uncovered a possible explanation for the mental sluggishness that often accompanies illness.Ketogenic diet helps tame flu virusA high-fat, low-carbohydrate diet like the Keto regimen has its fans, but influenza apparently isn't one of them. Mice fed a ketogenic diet were better able to combat the flu virus than mice fed food high in carbohydrates, according to a new study.NASA's Mars 2020 will hunt for microscopic fossilsScientists with NASA's Mars 2020 rover have discovered what may be one of the best places to look for signs of ancient life in Jezero Crater, where the rover will land on Feb. 18, 2021.

Fractured ice sheets on Mars
Where the two hemispheres of Mars meet, the planet is covered in broken-up terrain: a sign that slow-but-steady flows of icy material once forged their way through the landscape, carving out a fractured web of valleys, cliffs and isolated mounds of rock.Quick reference: ESA's vision and goals for Space19+

The satellite is being moved on its multi-purpose trolley under the supervision of Airbus staff and with the support of the spaceport team.

The first spacewalk to service the Alpha Magnetic Spectrometer (AMS) could not have gone better. Lead spacewalker ESA astronaut Luca Parmitano is imaged here hitching a ride on the International Space Station’s 16-metre long robotic arm to kick off the first of four ventures to service the particle physics detector on 15 November.
While all spacewalks are a carefully planned and detailed affair, the four spacewalks for AMS are exceptionally difficult as the bus-sized dark matter detector was never designed to be maintained in space. But after three successful years of delivering ground breaking science, the decision was made to extend its lifetime.

If a sci-fi spaceship does not come with hyperdrive then it is usually fitted with hibernation capsules instead. In movies from 2001: A Space Odyssey to Event Horizon, Alien to Passengers, fictional astronauts get put into ‘suspended animation’ to cross the vastness of space. Now ESA has investigated how real life crew hibernation would impact space mission design.
