Ancient Lava Reveals Earth's Magnetic Field Really Does Have a Cycle of 200M Years
We know that Earth's magnetic field is always shifting in its direction and its strength. Just how quickly these changes are happening is of great interest, considering this planetary feature keeps us all protected from violent cosmic radiation.

Physicists Create a Bizarre ‘Wigner Crystal’ Made Purely of Electrons
n 1934, Eugene Wigner, a pioneer of quantum mechanics, theorized a strange kind of matter — a crystal made from electrons. The idea was simple; proving it wasn’t. 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
It’s been hyped for decades. But scientific progress — and commercial competition — may soon produce a truly groundbreaking clean-energy technology.
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.

Sand bubbler crabs (or sand-bubblers) are crabs of the genera Scopimera and Dotilla in the family Dotillidae. They are small crabs that live on sandy beaches in the tropical Indo-Pacific. They feed by filtering sand through their mouthparts, leaving behind balls of sand that are disintegrated by the incoming high tide.
Basically, the tiny balls are a byproduct of the crabs' snacking. They don't eat the sand, but they do feed it through the bottom of an adapted mouth of sorts, filtering out all of the micronutrients that the high tide has brought in and dumped on the beach since their last feeding session.
In each burrow, the crab waits out the high tide in a bubble of air.
