Nano-watermark sorts fakes from genuines

Nanoga, an EPFL-based startup, has developed a technique to put a nanoscopic watermark onto glass or ceramic. Products with this watermark, which is invisible to the naked eye and only shows up under ultraviolet light, are ...

A star is about to go 2.5% the speed of light past a black hole

Since it was first discovered in 1974, astronomers have been dying to get a better look at the Supermassive Black Hole (SBH) at the center of our galaxy. Known as Sagittarius A*, scientists have only been able to gauge the ...

Robots come to each other's aid when they get the signal

Sometimes all it takes to get help from someone is to wave at them, or point. Now the same is true for robots. Researchers at KTH Royal Institute of Technology in Sweden have completed work on an EU project aimed at enabling ...

Chemists establish fundamentals of ferroelectric materials

Ferromagnetic materials, like compass needles, are useful because their magnetic polarization makes them rotate to align with magnetic fields. Ferroelectric materials behave in a similar way but with electric, rather than ...

DSCOVR is the linchpin of next-generation space weather forecasts

NOAA's first space weather satellite, DSCOVR, has completed instrument validation and will go operational on July 27, when it will take over the role of monitoring potentially damaging space weather storms as they approach ...

Ultra-cold atoms may wade through quantum friction

Theoretical physicists studying the behavior of ultra-cold atoms have discovered a new source of friction, dispensing with a century-old paradox in the process. Their prediction, which experimenters may soon try to verify, ...
