Search engines have come to define how most of us interact with digital information. But, if you think about it, they’re still pretty limited. We can search for words and, in recent years, Google Images allows us to search by picture. Want to search, though, for the flavor of apple, or the notes of the song you can’t remember the name to? You’re still out of luck.
However, researchers are making headway in another kind of novel search — searching by 3-D object. And that’s only going to become more useful in a world with growing access to 3-D printers.
If you live in North America and clear skies are in the forecast, then you’re in for a treat.
A partial solar eclipse will be visible across most of North America this afternoon. Unfortunately, people who live in the far northeast will miss the show, since the sun will set before the action begins. Read More
We all know you can’t judge a book by its cover, but now paleontologists are learning you can’t judge a dinosaur by its forearms.
For over 50 years, everything archaeologists knew about the ostrich-like dinosaur Deinocheirus mirificus was based on just two giant forearms unearthed in 1965. Understandably, the dinosaur represented one of the great unsolved mysteries in paleontology. However, two recent fossil discoveries have exposed the true identity of D. mirificus, and, boy, was it a big surprise. Read More
The same cells that give Darek Fidyka his sense of smell are also helping him walk again.
The Bulgarian man, who was paralyzed after a knife attack in 2010, can walk after doctors in Poland transplanted nerve cells from his nose into his severed spinal cord. The successful operation was the first of its kind for regenerative medicine, and Fidyka is believed to be the first man to walk again after having a completely severed spinal cord. Read More
It’s well known that a stress-filled lifestyle can lead to high blood pressure, insomnia and a host of other chronic health issues. Now, you can add type 2 diabetes to that list.
Past studies have partly linked stress with the onset of diabetes, but the mechanisms behind why this happens were poorly understood. In a new study, researchers provide evidence of a direct link between psychological stress and biological dysfunction.
There’s a new tool for researchers in pursuit of a cure for Alzheimer’s disease: lab-grown brains.
For the first time, neuroscientists from Massachusetts General Hospital have grown functioning human brain cells that develop Alzheimer’s disease in a petri dish. The breakthrough offers researchers a new method to test cures and decipher the origins of the disease. Read More
Lockheed Martin Corp. on Wednesday said its engineers had made a breakthrough in the race to build a nuclear fusion reactor.
The company’s secretive research unit, Skunk Works, claims that within a decade it’ll develop and deploy a nuclear fusion reactor that’s powerful enough to light over 80,000 homes, yet small enough to fit in the back of a truck. If the company succeeds, it would mark a major milestone in mankind’s pursuit of a viable nuclear fusion power source. Read More
For sea otters, a trip to the dentist is no sweat.
The protective enamel on their teeth is more than twice as strong as humans’ enamel — but it wasn’t always this way. Long ago, scientists say in a new study, early humans’ teeth were just as strong as sea otters’ clam-crunching pearly whites. And this finding could be a key to understanding our earliest ancestors’ dietary habits. Read More
Skydiving, winning a sexy sports car or scaling Mt. Everest sure sound like extraordinary experiences that would fill us with boundless joy to last a lifetime. But a new study finds that’s not always so: extraordinary experiences can actually generate unhappy feelings as well, because others in your ordinary social group are unable to relate to your stories.
The healing powers of poop are now available in pill form — and a new study has found that just two days of the treatment can cure a dangerous infection that kills 14,000 Americans per year.
The pills take the place of fecal transplants, which have gained credibility in recent years as a method of treating Clostridium difficile infection, but which require delivery by enema or a tube down the digestive system. Scientists say the pills, which contain filtered, healthy fecal matter, offer a cheap, convenient and safer way to “make the medicine go down.” Read More
