Curiosity rover collects fourth scoop of Martian soil

23.10.2012, Science Daily

NASA's Mars rover Curiosity shook a scoopful of dusty sand inside its sample-handling mechanism on Sol 75 (Oct. 21, 2012) as the third scrubbing of interior surfaces of the mechanism. The rover team is instructing the rover to deliver a sieved sample from this scoopful -- the mission's fourth -- onto Curiosity's observation tray on Oct. 22 and plans to analyze another sample from the same scoopful with the Chemistry and Mineralogy (CheMin) instrument this week.

For the first time: Meanders in the Lab

07.10.2012, Journal of Geophysical Research

A team from Utrecht University in the Netherlands succeeded for the first time to produce an actively meandering river in a flume experiment. While it is relatively easy to produce braided channels in the lab, meandering streams are notoriously hard to produce. The Utrecht team's innovation includes a special sand mixture and a new way of feeding the upper end of the model river.


New cure to improve condition of progeria patients
