Magnetic invisibility sounds simple in theory. Place the right materials around an object and magnetic fields flow around it as if nothing were there. Reality has been far messier. For nearly two ...

Add Yahoo as a preferred source to see more of our stories on Google. Since ancient times, people have experimented with light, cherishing shiny metals like gold and cutting gemstones to brighten ...

Rather than building stronger ocean-based structures to withstand tsunamis, it might be easier to simply make the structures disappear. A collaboration of physicists from the Centre National de la ...

A team of researchers in South Korea are developing an artificial “skin” that could allow soldiers to perfectly blend in with their surroundings. Such a cloak could make them invisible not only to ...

For nearly 20 years, physicists and engineers have chased the idea of invisibility. Early efforts focused on hiding objects from light using so-called metamaterials with extreme and often unrealistic ...

Scientists exploring a novel but highly promising avenue of cancer treatment have developed a type of "invisibility cloak" that helps engineered bacteria sneak through the body's immune defenses. The ...

WASHINGTON, April 19–Invisibility cloaks are seemingly futuristic devices capable of concealing very small objects by bending and channeling light around them. Until now, however, cloaking techniques ...

University of Utah mathematicians developed a new cloaking method, and it’s unlikely to lead to invisibility cloaks like those used by Harry Potter or Romulan spaceships in “Star Trek.” Instead, the ...

The solution published last month in the journal Physical Review Letters examines processes for linear wave disruption. The shielding concept uses rows of pillars placed in a cylindrical pattern ...

Engineers at Duke University, North Carolina, have used 3D printing to create an object that can shield against detection from microwave beams. Michelle Starr is CNET's science editor, and she hopes ...
