Stars memorize rebirth of our home galaxy

The Milky Way galaxy has died once before and we are now in what is considered its second life. Calculations by Masafumi Noguchi (Tohoku University) have revealed previously unknown details about the Milky Way. These were published in the July 26 edition of Nature. |SOURCE| Stars formed in two different epochs through different mechanisms. There [...] Read more

Shape-shifting material can morph, reverse itself using heat, light

A new material developed by University of Colorado Boulder engineers can transform into complex, pre-programmed shapes via light and temperature stimuli, allowing a literal square peg to morph and fit into a round hole before fully reverting to its original form. |SOURCE| The controllable shape-shifting material, described today in the journal [...] Read more

World's smallest transistor switches current with a single atom in solid state

At Karlsruhe Institute of Technology (KIT), physicist Professor Thomas Schimmel and his team have developed a single-atom transistor, the smallest transistor worldwide. This quantum electronics component switches electrical current by controlled repositioning of a single atom, now also in the solid state in a gel electrolyte. The single-atom [...] Read more

These Swirls of Light Could Be Signs of a Previous Universe Existing Before Ours

If our Universe happened to be locked in an eternal heartbeat of expansion and collapse, black holes would leave an impression. And it could look just like a number of swirls recently detected in the faint echo of light at the edge of space. |SOURCE| It's hardly the smoking gun for what's called the conformal cyclic cosmology (CCC) model, [...] Read more
