Scientists create a rare fifth form of matter in space for the first time ever

For a few minutes on Jan. 23, 2017, the coldest spot in the known universe was a tiny microchip hovering 150 miles over Kiruna, Sweden.

The chip was small — about the size of a postage stamp — and loaded with thousands of tightly-packed rubidium-87 atoms. Scientists launched that chip into space aboard an unpiloted, 40-foot-long (12 meters) rocket, then bombarded it with lasers until the atoms inside it cooled to minus 459.67 degrees Fahrenheit (minus 273.15 degrees Celsius) — a fraction of a fraction of a degree above absolute zero, the coldest possible temperature in nature.

Could ‘solid’ light compute previously unsolvable problems?

solid light

Princeton University researchers have begun crystallizing light as part of an effort to answer fundamental questions about the physics of matter. The researchers are not shining light through crystal – they are transforming light intocrystal.

Scientists discover a way to create matter from light

light

Scientists discovered a technique that should produce electrons and positrons by colliding two sets of super-energetic photons.

For a long time, scientists have theorized that you can create matter from light by colliding photons. Proving that theory has been a different story — you need the right high-energy particles to even think of trying. However, it looks like that once-impossible dream is close to becoming reality.

Brain’s ‘Fairness’ Spot Found

brain-unfair 3214

At some point in our lives, we’ve all cried “It’s not fair!” In fact, it’s human nature for us to dislike unequal situations, and we often try to avoid or remedy them. Now, scientists have identified the first evidence of this behavior’s neurological underpinnings in the human brain.

The results show that the brain’s reward center responds to unequal situations involving money in a way that indicates people prefer a level playing field, and may suggest why we care about the circumstances of others in the first place…

New Telescope To Attempt To Catalog Entire Night Sky

New Telescope To Attempt To Catalog Entire Night Sky 

The Large Synoptic Survey Telescope (LSST) is “a proposed ground-based 6.7 meter effective diameter (8.4 meter primary mirror), 10 square-degree-field telescope that will provide digital imaging of faint astronomical objects across the entire sky, night after night.” What’s that mean? Well, it means, if it’s built, we’ll have a telescope attempting to catalog the entire night sky into an absolutely massive 150 petabyte database. Awesome!
