Scientists uncovered a new state of matter that could lead us to many exciting new forms of quantum computing and teleportation.
A genus of Queensland marsupial lion that, in its heyday, would have had other animals “shaking in their boots”, is reclassified to be entirely new.

Researchers have recently discovered two of the genes that govern this weird-looking salamander’s ability to regenerate limbs, eyes, and even its brain.
Everybody feels negative emotions once in a while, but these emotions have a stronger effect on your health than you may realize. Every time you think about regrets, experience resentment or replay bad memories in your head, your body suffers just as much as your mind. That’s why harboring negative emotions can lead to devastating long-term disease.
But there is one simple solution: forgiveness. Trouble is, our culture seems to perceive forgiveness as a sign of weakness, submission, or both. This makes it harder to actually do the work to forgive people who’ve done you harm.
Turbulence is everywhere—it rattles our planes and makes tiny whirlpools in our bathtubs—but it is one of the least understood phenomena in classical physics.
Turbulence occurs when an ordered fluid flow breaks into small vortices, which interact with each other and break into even smaller vortices, which interact with each other and so-on, becoming the chaotic maelstrom of disorder that makes white water rafting so much fun.
But the mechanics of that descent into chaos have puzzled scientists for centuries.
Betelgeuse has been the center of significant media attention lately. The red supergiant is nearing the end of its life, and when a star over 10 times the mass of the Sun dies, it goes out in spectacular fashion. With its brightness recently dipping to the lowest point in the last hundred years, many space enthusiasts are excited that Betelgeuse may soon go supernova, exploding in a dazzling display that could be visible even in daylight.
While the famous star in Orion’s shoulder will likely meet its demise within the next million years—practically couple days in cosmic time—scientists maintain that its dimming is due to the star pulsating. The phenomenon is relatively common among red supergiants, and Betelgeuse has been known for decades to be in this group.
Coincidentally, researchers at UC Santa Barbara have already made predictions about the brightness of the supernova that would result when a pulsating star like Betelgeuse explodes.
Scientists at the University of Sussex have measured a property of the neutron—a fundamental particle in the universe—more precisely than ever before. Their research is part of an investigation into why there is matter left over in the universe, that is, why all the antimatter created in the Big Bang didn’t just cancel out the matter.
The team—which included the Science and Technology Facilities Council’s (STFC) Rutherford Appleton Laboratory in the UK, the Paul Scherrer Institute (PSI) in Switzerland, and a number of other institutions—was looking into whether or not the neutron acts like an “electric compass.” Neutrons are believed to be slightly asymmetrical in shape, being slightly positive at one end and slightly negative at the other—a bit like the electrical equivalent of a bar magnet. This is the so-called “electric dipole moment” (EDM), and is what the team was looking for.
This is an important piece of the puzzle in the mystery of why matter remains in the Universe, because scientific theories about why there is matter left over also predict that neutrons have the “electric compass” property, to a greater or lesser extent. Measuring it then it helps scientists to get closer to the truth about why matter remains.
