Open wide...It's time to brush up on your dental health with the help of the Oral-B SmartSeries electric toothbrush, which gives your pearly whites the once-over and connects to your phone via Bluetooth. It's a bluetoothbrush!
Experts reckon you're supposed to brush your teeth for two minutes each session, but most people don't. To get you into the habit of brushing properly, the SmartSeries talks to your phone via Bluetooth 4.0 and shows a countdown on your phone to make sure you don't short-change your chompers. And at certain intervals, the brush vibrates … Read more
Using whole-body scans to screen for cancer presents such a catch-22, especially in kids. While traditional radiation scanners like PET and CT are good at finding cancer, they expose patients to radiation that can be harmful and even induce cancer later in life -- more so in younger patients, because their cells are still dividing quickly and because, with more years ahead of them than adults, children also have a higher chance of being exposed to more radiation down the line.
The scenario is all too typical -- you're walking down the street puffing on an e-cigarette, just wishing you could use the little metal nicotine stick to make a phone call... How handy would that be?
Well, dreams can come true.
A company called Supersmoker has come up with an e-cigarette it claims is the world's first to double as a Bluetooth headset and device that streams MP3s from a smartphone. That's right, a musical cell phone cigarette.
"Never seen before! An electronic cigarette with Bluetooth functionality," the company writes on its Web site. "… Read more
Crazy-good vision sounds like something a character in a game might possess. But a researcher at the University of California at Riverside has invented an app that promises to bestow users with the gift of super-sight -- in real life.
Aaron Seitz, a UCR professor of psychology and developer of the Ultimeyes app, along with several colleagues, just published research in the journal Current Biology indicating that baseball players who used the Ultimeyes app for 30 25-minute sessions were able to improve their vision by an average of 31 percent. That's impressive enough, but what's truly amazing is that some players saw their vision go beyond normal 20/20 to 20/7.5, meaning they could see at 20 feet what someone with normal vision couldn't see beyond 7.5 feet.
The best part of the news? While the researchers tested the app on baseball players, who can obviously benefit from being able to see a flyball clearly, anyone can download and use the app by visiting the Ultimeyes Web site, which I did. … Read more
For months, the financial news channels have put on the air self-styled experts warning that Tesla was a house of cards -- no Netflix pun intended -- fated to collapse.
Even though Tesla's stock price quadrupled in 2013, shares pulled back on worries about the potential flammability of the Model S' batteries. Separately, Tesla announced a recall of charging equipment for a software … Read more
When looking to examine the heart and blood vessels, the images scientists get from techniques like cross-sectional ultrasounds can provide limited information.
"If you're a doctor, you want to see what is going on inside the arteries and inside the heart, but most of the devices being used for this today provide only cross-sectional images," explained F. Levent Degertekin, a professor in the George W. Woodruff School of Mechanical Engineering at Georgia Tech. "If you have an artery that is totally blocked, for example, you need a system that tells you what's in front of you. You need to see the front, back, and sidewalls altogether."
Such a system may now be on the horizon, thanks to Degertekin and a team of researchers at Georgia Tech. They've developed a minuscule sensor that could travel through the bloodstream to send highly detailed 3D images back to an external sensor. … Read more
MAUNA KEA, Hawaii -- I was recently having lunch at a lovely and only slightly overpriced cafe overlooking the Pacific in the historic resort region of Kailua-Kona on the dry side of Hawaii's "Big Island" (the island itself is also named Hawaii). I hopped in a rental car and traveled 60 miles by road, ascending nearly 3 miles in elevation from the dry, breezy coast through thick clouds shedding rain and hail onto my windshield, and finally reemerged into sunshine in the last few miles of the journey as I approached the Mauna Kea observatory complex, a collection of more than a dozen advanced telescopes that arguably serve as the eyes of mankind.
As technology has advanced over the centuries, we've been able to look exponentially farther into the depths of the universe with each new generation of super-sophisticated telescopes and supporting stargazing instruments. But somewhat ironically, getting top performance out of this equipment has meant locating it in increasingly isolated and even extreme spots around the globe, like Spain's Canary Islands, Chile's Atacama Desert, or here, on top of a 13,800-foot dormant volcano in the middle of the Pacific Ocean that last erupted about 4,500 years ago. … Read more
Amanda Boxtel's doctors told her she'd never walk again. But her new 3D-printed exoskeleton says otherwise.
In 1992, Boxtel was paralyzed from the waist down in a catastrophic skiing accident. But 22 years later, thanks to a groundbreaking 3D-printed robotic suit developed by 3D Systems and EksoBionics, she's able to stand up and move around on her own. … Read more
There's a lot of talk at the Olympics about history as athletes try to outdo their predecessors on the slopes, ice, and luge tracks in Sochi. It seems that Mother Nature herself wants to get in the game too, because She's hurling a huge asteroid at our planet almost a year to the day a space rock, measuring 65 feet in diameter, slammed into Russia. The incident released the energy equivalent to 20-plus atomic bombs.
No life was lost in the February 15, 2013, ordeal, but it did cause injuries and significant property damage in the area.
This latest Earth-bound asteroid, named 2000 EM26 and known as a Potentially Hazardous Asteroid (PHA), is due to be at its closest to Earth tonight.… Read more
Brain tumors known as Glioblastoma multiform cancer (GBM) are a particularly insidious form of the disease because they just don't stay still. They travel through the brain by sliding along blood vessels and nerve passageways. This means that sometimes they move to parts of the brain where surgery is extremely difficult -- if not impossible -- or that even if the bulk of a tumor can be removed, chances are good its tendrils would still exist throughout the brain.
Scientists at Georgia Tech may have come up with a novel solution for this problem; though, it may be years before the technique can be used on humans. It involves creating artificial pathways along which cancer can travel. These pathways could route cancer to a more easily operable area, or even to a deadly drug located in a gel outside the body. … Read more
