We already know that our memories are not always as accurate as we would like. According to a team of scientists at John Hopkins, one area where these inaccuracies manifest is in our perception of color. 

In their experiments, the team got participants to pick the “best” color from a wheel of 180 colors, to represent categories like pink, green and blue. They were then shown a color square for a … Read More → "Studies show that you can’t remember colors as well as you think"

Two years back, YouTuber Styropyro, also known as ‘The DIY Laser Guy, caught the internet’s attention with his homemade ‘lightsaber’. 

The three-watt mechanism dwarfs in comparison to his latest innovation–a 40-watt ‘laser shotgun’. 

Styropyro demonstrates the power of the contraption in the video below, by testing the ray on objects such as balloons, a ping-pong ball, flash paper and wood.

Narrowing the gap between smartphone photographers and studio photographers is the novel ‘Tric’–the world’s first wireless flash trigger. 

This system comprises two components–a physical unit that you connect to your speedlight or strobe, and the ‘Tric’ camera app that instructs the unit to trigger the flash each time you activate the shutter on your iPhone.

The holographic technology that we’ve seen from Star Wars might become a reality sooner rather than later. 

Introducing the Bleen, a 3D projection system that works without the bulky 3D glasses, using large-scale 3D reconstruction to create a moving holographic image. Simply place the device in a living room, office or gallery and watch holographic images up to a height of eight feet in realistic optical presence and spatial … Read More → "This holographic 3D projector may be the future of home entertainment"

Taylor toggles another switch, energizing the vacuum pumps.

He and Brinsmead and Phaneuf watch the gauge as the air is sucked out of the reaction chamber and the pressure decreases to the equivalent of 100,000 feet above sea level . . . then the space station’s orbit . . . then the surface of the moon.

A researcher at Massachusetts General Hospital has successfully grown the world’s first biolimb, The Washington Post reports. It’s a rat’s forearm and hand, and it looks a little smaller than an adult human’s thumb. Researchers are hopeful this could be the first step toward growing fully functional limbs in labs.

“We’re focusing on the forearm and hand to use it as a model system and proof of principle,” Harald Ott, the researcher who grew the limb, told New Scientist. “But the techniques … Read More → "Researchers have grown a partially functioning rat limb in a lab"

It sounds like something out of a science fiction novel, but now we have a substance that could one day allow doctors to activate different parts of your brain using nanoparticles and magnetic fields. It’s even possible that this area of research could one day make our brains programmable.

When people lose limbs, they often report feeling pain in the limb that’s no longer there. Phantom sensations also seem to extend to people who lose their eyes, according to a new study. And the symptoms include seeing ghosts.

As many as 60 percent of patients experience phantom eye syndrome, a group of researchers report in the journal Opthalmology. Some patients who had an eye removed due … Read More → "People with no eyes still see ghosts"

For the last few weeks since its launch, the experimental LightSail satellite has been orbiting Earth, unable to make ground contact thanks to a software glitch. But earlier today, the spacecraft’s handlers successfully deployed the little craft’s gigantic sail.

Following the initial launch on May 20, LightSail went offline due to a software glitch. It spent eight days … Read More → "Bill Nye’s solar-powered space-sailer has woken up"
