You have an excellent supply of stem cells right behind your eye

As we age, vision problems are unavoidable. Age-related macular degeneration breaks down a thin layer of cells in the back of your eye — the retinal pigment epithelium (RPE) — on the way to causing vision loss. » 1/09/12 5:00pm 1/09/12 5:00pm

Black holes may have been fundamental building blocks of the early…

Most astronomers agree that at the center of every galaxy lies a supermassive black hole. But how did these gravitational monsters form? Now it seems that they may have been here since the beginning of time. » 6/15/11 1:31pm 6/15/11 1:31pm

Genetically engineered cell becomes world's first living laser

It looks like we're one step closer to having laser vision (or at least, laser-based diagnostic and therapeutic techniques). Researchers at Harvard Medical School and Massachusetts General Hospital in Boston have genetically engineered the world's first "living laser." That's right - a living cell can shoot laser… » 6/13/11 1:22pm 6/13/11 1:22pm

A mutant that kills cancer

A medical researcher has discovered that a mutant gene once believed to cause cancerous tumors is actually the perfect weapon to stop them. Weirdly, it's possible that benign tumors may be the key to stopping cancer. » 6/06/11 8:00am 6/06/11 8:00am

The Moon may have the same proportion of water as Earth does

Today, a group of scientists announced that beneath the surface of the Moon there may be as much water as we have on Earth. This revelation could change everything we know about the Moon — and pave the way for lunar colonies in the next twenty years. » 5/26/11 11:00am 5/26/11 11:00am

A tiny antenna could revolutionize solar panels

One of the big problems with current solar cells is that they aren't able to absorb infrared light — which accounts for around a third of the solar energy that hits the planet. A new type of nanomaterial, a tiny antenna, could solve that problem and make our solar panels far more efficient. » 5/06/11 10:30am 5/06/11 10:30am

Making nanomaterials just got a lot easier

Graphene is pretty cool stuff. It's the foundation of a lot of nanomaterials, and when it's only a single atom thick, it can stretch eternally in two dimensions. When it's more than one atom thick it behaves very differently, becoming graphite (which you often find in pencils). We already know a pretty easy way to … » 3/04/11 8:30am 3/04/11 8:30am

A topical gel that can reverse sudden hearing loss

In early middle age, tens of thousands of people experience an inexplicable, rapid hearing loss in one ear. Now doctors have discovered a simple topical gel that, when applied to the ear, restores hearing in over half their patients. » 11/25/10 6:30am 11/25/10 6:30am

Revolutionary eye implants have restored sight to the blind

By tucking high-tech implants inside people's eyes, researchers in Germany have given three blind people the ability to see. » 11/03/10 11:17am 11/03/10 11:17am

A cure for the common cold at last...and why it's taken this long

Learning there's no cure to the common cold is many people's first introduction to the frustrating limits of medical science. A new breakthrough could prove that old saying wrong. » 11/02/10 2:15pm 11/02/10 2:15pm

X-Ray Hackers Show Tinest Crystalline Structure Ever Seen

What does this one-micron sized object look like to you? Despite what Freud would say, that boldly thrusting little guy is a microcrystal, once classified as a powder too tiny to be imaged using X-rays. But a bunch of European X-ray fiends have rigged up a special X-ray diffractor at the European Synchrotron Radiation… » 10/04/07 8:42am 10/04/07 8:42am
