How to Trick Your Brain Into Seeing This Black and White Image In Full Color (Video)

bw color

Our eyes are made up of two types of cells: rod cells, which are primarily responsible for perceiving light, and cone cells, which handle color. There are three types of cones — ones that handle green wavelengths of light, ones that handle blue and ones that handle red. If you overstimulate one type of cone by flooding your vision with a bunch of that color, those cones will become temporarily unresponsive. As a result, your eyes are forced to rely on the other two types of cones,

Study: Miami and New Orleans Will Be Lost to Rising Sea Levels, No Matter What We Do

rising seas

Though a handful of people continue to deny its existence, the consequences of climate change are becoming more and more severe with each passing day. Take the issue of rising sea levels, for example. According to a new study published in the Proceedings of the National Academy of Sciences on Monday, Miami, New Orleans and a handful of other major cities are doomed to be swallowed up by rising sea levels, no matter what steps we take to try to save them. In making their projections, the researchers looked at a number of different

Video: This Scale Model of the Solar System Stretches 7 Miles Across the Desert

solar system to scale

Space is big. REALLY big. And our solar system is no exception. If you don’t include Pluto (which was demoted from planet status a few years back), one would have to travel approximately 2.8 billion miles to get from the Sun to the outermost limits of our solar system — the equivalent of traveling all the way around the Earth 112,440 times. Because of its massive size, it’s extremely difficult to show all the features of our solar system together on an accurate scale. Luckily for us, filmmakers Alex Gorosh and

Scientists Prepare to Reanimate 30,000-Year-Old Virus Found Frozen In Siberian Wastelands


Earlier this week, a team of French researchers announced plans to wake up an ancient virus that has been lying dormant in Siberia’s frozen wastelands for the last 30,000 years. The virus, known as Mollivirus sibericum, was found in the permafrost of northeastern Russia and is the fourth prehistoric virus to be discovered since 2003. While it’s unlikely that the virus will pose any serious health threats, the researchers still plan to confirm that the bug is unable to infect humans or animals before they reanimate it.

How Telling People About Your Goals Makes You Less Likely to Accomplish Them

telling people your goals

When you set yourself a new goal, it might seem like a good idea to tell others about it. But if you really want to accomplish that goal, your best bet is to keep it to yourself. To most people, that probably sounds counter-intuitive. Telling your peers about your goal should add some social pressure that gives you extra motivation to accomplish it, right? Here’s the problem: when you tell someone your goal (let’s say you want to lose 20 pounds), their

This Foldable 50-Cent Microscope Can Detect Malaria in a Single Drop of Blood

Bioengineering professor Manu Prakash is a major proponent of what he calls “frugal science”: using inexpensive materials to craft cheap versions of high-tech science equipment. Prakash’s frugal science inventions include a $5 microfluidic chemistry lab capable of testing and analyzing a wide array of substances, and a water-based computer that uses droplets suspended in a magnetic field to properly synchronize multiple operations. But perhaps the most impressive of Prakash’s inventions is the Foldscope: a foldable paper microscope that costs just 50 cents

No, The World Is NOT About to Experience A “Mini Ice Age”

You may have seen a number of headlines over the past few days announcing the imminent arrival of a “mini ice age” in the next 15 years. As the sensational story gained momentum, all sorts of outlets picked it up, from Wired and Science Alert to MarketWatch and the Huffington Post. Heck, even The Weather Channel ran a segment on it. Unfortunately, all of these predictions of a “mini ice age” are simply the result of bad science reporting. The original story was based on

Watch: SpaceX Rocket Explodes and Disintegrates Minutes After Launch

This morning, SpaceX geared up for its third attempt at recycling one of its Falcon 9 fuel rockets by landing it on a floating barge in the ocean. The first attempt was on target, but lacking in control; the second attempt was extremely close, but still failed. SpaceX’s engineers were hoping that the third time would be the charm with today’s launch. But as it turns out, they never even got a chance to try the barge landing. About two minutes after launch, SpaceX’s Dragon supply rocket

Vantablack: British Company Invents Material So Black You Can Barely See It

British technology company Surrey NanoSystems has developed a strange material that is so black it absorbs all but 0.035 percent of visual light, making it the world’s “blackest material”. According to The Independent… “It is so dark that the human eye cannot understand what it is seeing. Shapes and contours are lost, leaving nothing but an apparent abyss.”   The material, which is being call “Vantablack”, is a coating that is made by packing carbon nanotubes side by side. Each nanotube

This 3-Cent Droplet Lens Turns Your Smartphone Into A Powerful Microscope

pdms lens

Researchers from the University of Houston have developed an optical lens that can magnify images up to 120 times when attached to the average smartphone. The droplet-shaped lenses, which are made of a polymer called polydimethylsiloxane (PDMS), are extremely inexpensive — the researchers estimate that it would cost just 3 cents a piece to produce them in bulk. Yu-Long Song is one of the scientists who worked on the lens. “Nearly everyone has a smartphone,” Sung said. “Instead of using a $30 or $50 attachment that students might
