What Color Is This Dress? Science Answers

By Lisa Raffensperger | February 27, 2015 10:28 am

It’s Friday on the Internet, and we’re all abuzz with the latest meme  but, happily, for once it’s a meme with some fascinating science behind it.

The question at hand, if you haven’t been asked it already, is what color is this dress, below? The results are remarkably divided. An informal Buzzfeed poll indicates that about 75 percent of people perceive it to be white and gold.

‘Antifreeze’ Protein, Borrowed From Ticks, Could Battle Frostbite

If you live in a cold climate, some days any exposed skin is at risk of frostbite. But if we had antifreeze coursing through our veins, we’d be resistant to winter’s bite.

And that’s not as crazy as it sounds. Scientists have recently demonstrated that mice, genetically engineered to produce an antifreeze protein, are better able to fight off frostbite. Although other animals have this survival skill, it’s the first time it’s been replicated in a mammal. Read More

Just Based on DNA, Scientists Can Construct an Image of Your Face

Putting pencil to paper has been the tried-and-true method to illustrate the faces of wanted criminals, but new technology is changing this traditional approach. DNA, rather than an artist’s skill, is an emerging tool to recreate the face behind a crime.

The new forensic technique is called DNA phenotyping. It relies on DNA, found for instance in a drop of blood, to create a simulated face based upon genetic markers. Although the science still has room to grow, start-up companies in the United States are already producing DNA-based sketches to assist police departments in criminal investigations. Read More

X-Rays of Buddhist Statue Reveal Mummified Monk

It’s not surprising that Southeast Asia is home to countless ancient Buddha statues, but when one of those statues contains a mummified monk, that is certainly a surprise.

A mummified monk is exactly what researchers at the Netherland’s Meander Medical Center found when they placed a 1,000-year-old Chinese Buddha statue inside a CT scanner. Researchers believe the statue contains the body of a Buddhist master named Liuquan, who may have practiced the tradition of “self-mummification” to reach his final resting place.

Scientists Find the Quietest and Noisiest Places in the U.S.

Humans love to make a racket. From our car horns to jackhammers, noise is a constant companion wherever people come together to live, work and play.

So where can a person go to find some peace and quiet?

Thanks to data gathered by the National Park Service, it’s now easy to find the nation’s sanctuaries of silence. Researchers conducted more than 1.5 million hours of acoustical monitoring at 546 different sites to construct a map (above) that shows the average noise levels throughout the U.S. on a typical summer day. The basic takeaway: The further you head west, the quieter life gets. Read More

Genetically Modified Non-Browning Apples Are Approved in the U.S.

It’s a small victory for fruit-salad enthusiasts: The U.S. Department of Agriculture last week approved genetically modified apples that don’t brown when exposed to air.

The approval allows trees bearing this type of fruit, called Arctic apples, to be planted on U.S. soil and, once the FDA agrees, the produce could be sold in stores within a few years. Read More

Zoom Contact Lens Magnifies Objects at the Wink of an Eye

Swedish optics researchers are developing contact lenses that can zoom in on an object with the blink of an eye.

The prototype lenses, unveiled Friday at the American Association for the Advancement of Science annual meeting, can magnify objects up to 2.8 times and could someday be useful for patients with macular degeneration, a major cause of blindness and visual impairment in older adults.

A simple wink activates the telescopic lens, which could help people read and recognize faces more easily. Read More

Mysterious Clouds in Mars’ Atmosphere Baffle Scientists

Enormous cloud-like plumes reaching 160 miles above the surface of Mars have left scientists baffled. This is way beyond Mars’ normal weather, reaching into the exosphere where the atmosphere merges with interplanetary space. None of the conventional explanations for such clouds make sense – neither water or carbon dioxide ice nor dust storms nor auroral light emissions usually hit such heights.

These “mystery clouds” came as a surprise, in particular when considering they were first spotted by a string of amateur astronomers in 2012. After all, an international fleet of five orbiters and two rovers is currently operating on and around Mars, and one may be excused thinking the red planet has little left to hide and its exploration has become routine.

A survey of images from the Hubble Space Telescope and amateur astronomers revealed massive clouds had been seen on Mars before, but none as prominent as the 2012 observations.

So what caused these clouds? An international team of scientists led by Agustin Sánchez-Lavega has now published an investigation in the journal Nature.

LED Skylight Authentically Recreates the Sun’s Rays

Sunlight is a key factor architects take into account in their designs, but in most cases, they’re pretty much at the mercy of Mother Nature to provide it. However a new innovation may be set to change that.

An Italian company called CoeLux has developed an LED light that impeccably recreates the appearance of sunlight — so well that both human brains and cameras can’t tell the difference. Designers captured the color temperature and intensity of sunlight by recreating the same natural conditions that exist in Earth’s atmosphere, but on a nano scale. Read More
