Yesterday, Stephen Hawking and Yuri Milner made the mind-blowing announcement that they want to build a fleet of interstellar spacecraft that can travel at relativistic speeds—up to 20 percent the speed of light. But it’s not just about reaching our nearest star system, Alpha Centauri, although that is the new…
Can you imagine the idea of freezing light, stopping its photons in space as if time itself seemingly stood still? You are looking at it. German scientists have actually frozen the fastest thing in the universe for an entire minute. It's a major physics breakthrough.
There are no hospitals in space. The closest E.R. is back on Earth, and astronauts can't exactly jump in a cab to get there. So what happens if the sun burps out a massive blast of radiation while an astronaut is space-amblin' by?
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.
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.
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…
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.
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.
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.
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 …
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.
By tucking high-tech implants inside people's eyes, researchers in Germany have given three blind people the ability to see.
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.
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…
Scientists at Lawrence Berkeley National Laboratory say they've developed a new manufacturing process that allows them to build a material that could goose up the power output of solar cells, reaching efficiencies of 45% compared to the 25% to 39% currently possible. It's done using a tricky process of injecting…
