Entangled matter wave interferometer. Now with double dread

View of entangled atoms inside the interferometer. Credit: Stephen Burroughs, Thompson Group / JILA The team of researchers James K. Einstein originally referred to entanglement as creating a frightening action at a distance – the strange effect of quantum mechanics in which what happens to one atom in one way affects another atom elsewhere. Entanglement …

The discovery could significantly narrow the search for space creatures

Illustration of a red dwarf star orbiting a hypothetical exoplanet. Red dwarfs erupt with intense flares that can strip away a nearby planet’s atmosphere over time, or make the surface inhospitable to life as we know it. Credit: NASA/ESA/STScI/G. Bacon An Earth-like planet orbiting an M dwarf—the most common type of star in the universe—appears …

Butterfly wing patterns stem from ancient ‘junk’ DNA | Cornell Chronicle

Butterfly wing patterns have a basic plan to them, which is manipulated by non-coding regulatory DNA to create the diversity of wings that can be seen in different species, according to new research. The study, “Deep regulatory symmetry of the floor plan of the butterfly wing pattern,” published as a cover story in the October …

How almost a single human hair stopped the launch of SpaceX

Crew Dragon Endurance aboard a SpaceX Falcon 9 rocket on October 1, 2022. picture: SpaceX Engineers scoff that Level 1 diminution is a four-letter word, but there’s nothing funny about UFOs and their potential to cause disaster. The accident occurred on October 5 at approximately 10:25 a.m. ET, as the SpaceX platform crew was preparing …

The world’s oldest known star map was found hidden in a medieval manuscript

More than 2,100 years ago, the Greek astronomer Hipparchus mapped stars – and for a long time, this was considered the first human attempt to assign numerical coordinates to stellar bodies. But despite its fame, the existence of the treatise was known only through the writings of another well-known ancient astronomer named Claudius Ptolemy, who …

Electrical discharge from plants may alter air quality in ways we didn’t expect

When lightning flashes above, plants on the ground may respond in kind. Scientists have long known that plants and trees can emit small, visible electrical discharges from the tips of their leaves when the plants are trapped under the electric fields of high-powered thunderstorms. These secretions, known as corona, sometimes appear as faint blue sparks …

NASA’s Mars rover Curiosity arrives at an interesting salty location after a treacherous journey

After a treacherous journey, NASA’s Curiosity Mars probe has reached an area believed to have formed billions of years ago when the waters of the Red Planet vanished. This area of ​​Mount Sharp, Curiosity’s Martian land, is rich in salt minerals that scientists believe were left over when streams and ponds dried up. As such, …

A monster black hole has been detected nearby causing it to go about its business silently

Black holes are among the most amazing and mysterious things in the known universe. These giant gravitational planets form when massive stars undergo gravitational collapse at the end of their lives and shed their outer layers in a supernova explosion. Meanwhile, the stellar remnant becomes so dense that the curvature of spacetime becomes infinite in …
