Physicists Create a Bizarre βWigner Crystalβ Made Purely of Electrons
n 1934, Eugene Wigner, a pioneer of quantum mechanics, theorized a strange kind of matter β a crystal made from electrons. The idea was simple; proving it wasnβt. Physicists tried many tricks over eight decades to nudge electrons into forming these so-called Wigner crystals, with limited success. In June, however, two independent groups of physicists reported in Nature the most direct experimental observations of Wigner crystals yet.

Expert help needed to decode a rare piece of space history: the Lunokhod data tapes
Between 1970 and 1973, the Soviet space program achieved an amazing feat: landing and driving the first remote-controlled roving robots on the Moon called Lunokhod-1 and -2.
Their data and images have been published only partially and with great quality losses due to analog duplication, and a large fraction is thought to be lost.
It has now emerged that a set of tapes still exists.
Expert help is now needed to decode the images and data stored on these tapes in analog form.

Nuclear Fusion Revolution

Scientists at the National Ignition Facility, part of the Lawrence Livermore National Laboratory, announced that they had produced about 10 quadrillion watts of fusion power after blasting a hydrogen capsule with an array of laser beams. The burst lasted only a fraction of a second. But it offered significant new evidence that harnessing fusion energy could one day be feasible.
