A Cracked Piece of Metal Healed Itself in an Experiment That Stunned Scientists

Posted by in category: engineering

File this under ‘That’s not supposed to happen!’: Scientists observed a metal healing itself, something never seen before. If this process can be fully understood and controlled, we could be at the start of a whole new era of engineering.

A team from Sandia National Laboratories and Texas A&M University was testing the resilience of the metal, using a specialized transmission electron microscope technique to pull the ends of the metal 200 times every second. They then observed the self-healing at ultra-small scales in a 40-nanometer-thick piece of platinum suspended in a vacuum.

Cracks caused by the kind of strain described above are known as fatigue damage: repeated stress and motion that causes microscopic breaks, eventually causing machines or structures to break. Amazingly, after about 40 minutes of observation, the crack in the platinum started to fuse back together and mend itself before starting again in a different direction.

Unusual type of stellar object discovered beaming out radio waves

Posted by in category: cosmology

Astronomers have discovered a new type of stellar object that could change their understanding of extreme celestial bodies in the universe.

Initially, Curtin University doctoral student Tyrone O’Doherty spotted a spinning celestial space object in March 2018. The unfamiliar object released giant bursts of energy and beamed out radiation three times per hour.

In those moments, it became the brightest source of radio waves viewable from Earth through radio telescopes, acting like a celestial lighthouse.
