Scientists Made This Entire Mouse Transparent Using Detergent

Last year, scientists did the wacky and cool thing of making a mouse brain transparent. Now they've gone and done it to an entire mouse by pumping detergent through its veins. The transparent mouse looks like gross rodent jello (yes, there is a photo), but it's also an incredible new way to study what intact organs… » 7/31/14 5:19pm Yesterday 5:19pm

There Are Cells Inside Teeth That Can Turn Back Into Stem Cells

Inside each of our hard, calcified teeth is a small population of living stem cells that can differentiate into many types of tissue. The origin of those stem cells has long been unknown, but scientists may now have a completely surprising answer: Cells of the nervous system can migrate into the middle of a tooth and… » 7/31/14 2:10pm Yesterday 2:10pm

The Plan to Save Bluefin Tuna By Using Science to Farm It On Land

The bluefin tuna is a magnificent creature. A silvery torpedo, it grows as big as 1,000 pounds, swims as fast as cars, and survives the cold waters of the ocean, weirdly enough, as warm-blooded fish. Oh, it also happens to be pretty tasty as sushi. Thanks to our growing sushi appetites, the bluefin tuna seems likely… » 7/30/14 6:47pm Wednesday 6:47pm

This 1D Graphene Switches from Conductor to Insulator When It Stretches

You've heard all about the wonder properties of graphene, so come meet its one dimensional cousin, carbyne. A chain of single carbon atoms to graphene's two-dimensional layer of atoms, carbyne has some pretty amazing properties of its own. By one measure, it's the strongest material in the world (over graphene!), and… » 7/30/14 5:31pm Wednesday 5:31pm

One Super Common Bacteria Is Wasting Labs Millions in Research Money

Unless you're a biologist, the bacterium Mycoplasma probably will not strike fear in your heart. Our mouths are teeming with this tiny and usually harmless microbe. But when Mycoplasma finds its way into a petri dish of cells, it becomes a big and expensive headache. A new study finds that 11% of samples in… » 7/30/14 2:54pm Wednesday 2:54pm

OKCupid's Experiments Are Like a 2014 Version of This Old Romcom

OKCupid announced yesterday it had been messing with us—far more intrusively than Facebook had been. Among other things, the online dating site deliberately told some users they were great matches when they were in fact awful matches and vice versa. The whole scenario recalled for me, of all things, a 1998 romcom… » 7/29/14 8:00pm Tuesday 8:00pm

The Moon Might Be Littered With Fossils From Ancient Earth

Earth is an unforgiving place. Volcanoes erupt, rivers erode, continents break up—it's a small miracle every time a millions-of-years-old creature is found fossilized in rock. By comparison, the moon is dead and lifeless; astronaut footprints will be preserved forever in moon dust. So it's the moon that could hold the… » 7/29/14 4:18pm Tuesday 4:18pm

Why Russia Was Studying Space Lizard Sex In the First Place

For a brief moment, the internet was captivated by the thought of geckos copulating madly in a lost Russian satellite. Russia has since regained control of its lizard-sex orbiter, but the whole episode has gifted us an opportunity to consider a topic of extremely legitimate scientific interest. Namely, lizard sex in… » 7/29/14 12:27pm Tuesday 12:27pm

These Scarves Are Printed With the Outlines of Cities Aglow at Night

We've all seen the glowing fingerprints of cities after dark: Manhattan as an orderly grid, London a sprawling mess bisected by the winding Thames, the ring of Paris's arrondissements. The patterns are recognizable but abstract, just right on a silk scarf that lets you subtly broadcast your city allegiances. » 7/25/14 4:20pm 7/25/14 4:20pm

Bad Cell Phone Calls Could Actually Be Tracked to Detect Rainfall

Despite the many wonders of our modern cell phones, using them to call a real live human can kind of suck. The sound is fuzzy, the calls drop randomly, and a simple rainstorm can make it all even worse. But there is surprising upside to all this: we can monitor the quality of cell phone calls to track rain and floods… » 7/25/14 3:23pm 7/25/14 3:23pm

The 5 Massive New Telescopes That Will Change Astronomy Forever

The biggest building boom in the history of astronomy is upon us. In Chile and Hawaii and in space, astronomers are getting powerful telescopes that dwarf the current state-of-the-art instruments. When the mountain blasting and the mirror polishing are all done, we will have the clearest and most detailed views of… » 7/25/14 9:00am 7/25/14 9:00am

A Display-Tweaking Algorithm Could Let You Ditch Glasses and Contacts

I spend too much of my waking life staring at screens. If you're reading this, you probably do, too. So instead of putting things on or in front of our imperfect eyeballs to correct and protect them, how about rethinking the screens we're staring at? Researchers at Berkeley, MIT, and Microsoft have developed a… » 7/24/14 2:14pm 7/24/14 2:14pm

The Ice-Diving Robot That Could Look for Alien Life on Jupiter's Moon

The search for extraterrestrial life begins, often enough, on Earth. In this case, it's an Alaskan glacier, where the robot VALKYRIE is proving its ice-chomping abilities in a field test. VALKYRIE is supposed to one day land on Jupiter's moon, Europa, where it will drill through miles of ice to reach the liquid oceans… » 7/23/14 5:59pm 7/23/14 5:59pm

How to Turn An Old Satellite Dish Into a Working Radio Telescope

Radio telescopes, which you may remember Jodie Foster intently listening to for signs of alien life in Contact, pluck out radio waves from far away space. Ordinary communications satellite dishes also pick up radio waves, but of manmade origin. So hmm, how easily can you convert one into another? It's totally… » 7/23/14 4:21pm 7/23/14 4:21pm

The Lattice of Tubes Covering This Building Are a Natural AC System

If you have ever sweated through a summer in the city, you can thank those skyscrapers all around. Tall buildings trap heat that create urban heat islands. But what if you could create a building that cools the city instead? A building skin made of a series of tubes with evaporating rainwater can do just that. » 7/22/14 3:48pm 7/22/14 3:48pm
