Scientists produce laser light from human kidney cells, we get in touch with our inner Cyclops

Scientists have just created living laser light out of a human cell and some jellyfish protein, but it’s not quite as terrifying as it sounds. Developed by Malte Gather and Seok Hyun Yun at Massachusetts General Hospital, the new technique revolves around something known as green fluorescent protein (GFP) — a naturally glowing molecule found in jellyfish that can be used to illuminate living material. After genetically engineering a human kidney cell to express this protein, Gather and Yun wedged it between two mirrors in an inch-long cylinder, filled with a GFP solution. Then, they infused the system with blue light, until the cell began to emit its own pulses of bright green laser light. Researchers also noticed that the cell could regenerate any destroyed fluorescent proteins, potentially paving the way for scientists to conduct light-based therapy and medical imaging without an external laser source.

Heart-rate monitoring belt marks Bluetooth 4.0 milestone, stops to rest for Bluetooth 4.0 phones

Heart monitoring belt marks Bluetooth 4.0 milestone, stops to rest for Bluetooth 4.0 phones

Some firsts represent truly monumental achievements. Others, like the world’s first production-ready Bluetooth Low Energy heart-rate chest belt, are just a mouthful. This little black belt claims to be the very first of its kind, and promises to “spur the development of a whole new range of… health and fitness apps,” by harnessing the power of Bluetooth Low Energy to pump heart rate stats to your mobile phone. Of course, that deluge of new fitness apps will have to wait until a Bluetooth 4.0-compatible phone hits the market. In the meantime, we wouldn’t expect the black chest strap to pioneer any new fashion trends.

Cellphones Deemed "Possibly Carcinogenic" by World’s Leading Cancer Experts

The back and forth brawl between studies suggesting that cell phones do and don’t cause cancer just took a bold step toward the former camp today, with the World Health Organisation classifying cellphones as potential links to brain cancer. More »

Tokyo Opens Up to Green Curtains

Signs of summer have started to creep up on us in Japan and with last years temperatures breaking record highs, the sweaty season isn’t always so welcome. In a bid to combat the heat this year, residents in Tokyo are being encouraged to plant their own Green Curtain with local councils starting to give out free kits and seeds.

Green-Curtain

Since the nuclear incident in March many households are worried about the electricity blackouts that may be imposed over summer. Therefore, as we have blogged before, many groups and companies are stepping up efforts to conserve energy to avoid cuts in electricity in the months ahead. One area of Tokyo decided to give out full green curtain kits to 1000 residents, consisting of 2 goya seeds (a japanese bitter gourd), a 90cmx 180cm net and a guidebook. Other local governments have teamed up with NPO’s to give workshops educating the public on how simple it is to grow their own green curtain and also how effective the plants are at tackling increasing temperatures. The movement seems to be catching on and many schools and public buildings have taken on the project.

Green-Curtain-Project

Any visitor to Tokyo will note how little greenery there is in the city and despite an initiative developed in 2005 called the Tokyo Green Building Program there is a huge amount of wasted space atop buildings. The urban heat island effect contributes greatly to Tokyo’s oppressive heat and humidity each summer, according to a study by the Tokyo Metropolitan Government when the temperature of concrete rose to 55ºc the temperature on green areas was as low as 30ºc. More buildings adopting a green curtain or green roof similar to the Fukuoka Across Building, pictured below, would also have a great impact on the scenery around town, turning Tokyo into a greener concrete jungle, as well as providing relaxing areas for busy office workers to relax in between meetings.

Fukuoka-Across-Building

With Germany recently announcing it is to cease operation of all nuclear power plants by 2022, not only Japan but the world is starting to look for alternative ways to save energy and explore renewable sources. Handled correctly Japan stands to be able to take a leading role now in how it deals with its energy demands, and the role sustainable business and technology can drive the economy.

Docomo’s Updated Bike Sharing Service

Japanese mobile service provider NTT Docomo announced an update to their bike sharing scheme, called Interstreet, at the recent Wireless Japan exhibition held this week in Tokyo.

Docomo-Bikeshare-Wireless-Japan

Earlier in the year the company teamed up with Japanese company Pedal for a trial service whereby the public could locate and rent bikes from their phones. The new update includes a specifically designed app for Android users and new docking stations allowing a number of different payment methods and more bikes equipped with GPS tracking.

Docomo-Bikeshare-Wireless-Japan1

To rent the bikes users touch their Osaifu Keitai (wallet phone) enabled mobiles to the sensor pad on the machines and register their phone number and mail address on the touchscreen display. A confirmation mail is then automatically sent to the phone which users then touch to the locking mechanism. The lock automatically unlocks and the cyclist can then take the bike, the time is registered by the service and on the users phone. Those without FeliCa phones can use either a credit card or another emoney payment system.

Docomo-Bikeshare-Japan

The bikes have a holder for the Android phones mounted on the handle bars to make use of the free, specially designed app for the service, COSOADO. The app gives the user map information, highlights local attractions and shops, suggests routes and uses GPS to track where and how far the cyclists pedal. It can also display health information such as how many calories burned during the cycle and the route taken.

Docomo-Bikeshare-app

Once finished with, the bikes can be left at any of the other bike stations around the area, meaning that one way trips are also possible. Users are then charged automatically, via emoney from their registered phones, based on how long they have used the bikes for.

The health and wellness market is a growing sector globally and tying in smartphone capabilities for a more enhanced experience is an obvious update from Docomo. It would be nice if it could be tied in with a social service such as foursquare or twitter also, users could for example then compete with others for the most distance cycled or areas visited. It would have been simpler also if the whole registration process could have been done via the Android app, without having to go through the different steps each time users want to rent a bike. The key to how useful the service is though will depend on how widely it is implemented, and it would also be nice to see more initiatives made by the government for cycle lanes and paths, of which there is a distinct lack of at present in the city.

Ford car seat prototype keeps its sensors on your heart, so you can keep your eyes on the road

Chevy had the whole “Heartbeat of America” thing cornered in the 80s, but now its Ford’s turn to get in on the action. The car maker’s European research team unveiled a prototype car seat capable of monitoring a driver’s heart courtesy of six embedded electrodes, which can take measurements without coming in direct contact with skin. The technology, the latest in a recent string of health-related in-vehicle concepts from the company, can detect whether the driver is having a heart attack and transmit that information to the vehicle’s safety system. According to the researchers, the system is already highly accurate in its prototype state, making correct readings for 98 percent of drive time with 95 percent of the drivers tested. For more information on the system, check the video and press release after the break.

IBM’s Jeopardy-winning supercomputer headed to hospitals. Dr. Watson, we presume?

We always knew that Watson’s powers extended well beyond the realm of TV trivia, and now IBM has provided a little more insight into how its supercomputer could help doctors treat and diagnose their patients. Over the past few months, researchers have been stockpiling Watson’s database with information from journals and encyclopedias, in an attempt to beef up the device’s medical acumen. The idea is to eventually sync this database with a hospital’s electronic health records, allowing doctors to remotely consult Watson via cloud computing and speech-recognition technology. The system still has its kinks to work out, but during a recent demonstration for the AP, IBM’s brainchild accurately diagnosed a fictional patient with Lyme disease using only a list of symptoms. It may be another two years, however, before we see Watson in a white coat, as IBM has yet to set a price for its digitized doc. But if it’s as sharp in the lab as it was on TV, we may end up remembering Watson for a lot more than pwning Ken Jennings. Head past the break for a video from the University of Maryland School of Medicine, which, along with Columbia University, has been directly involved in IBM’s program.

Somnus Sleep Shirt watches while you sleep, won’t be creepy about it (video)

Monitoring sleep patterns usually involves a hydra of sensors that keep track of brain activity, muscle movements and heart rates, but a startup called Nyx Devices has developed a new night shirt that can evaluate the quality of a user’s slumber by analyzing only breathing patterns. The form-fitting Somnus Sleep Shirt is embedded with two sensors that keep track of a person’s overnight breathing and transmit this information to a small data recorder, which slides into the lower corner of the nightie. When a user wakes up, he or she can upload their stats to Nyx’s website, where they can generate more detailed analytics and log their caffeine and alcohol intake to find out how all those martini lunches affect their snoozing. Co-inventor Matt Bianchi, a sleep neurologist at Massachusetts General Hospital, thinks the Somnus could help patients suffering from insomnia, who often have difficulty determining how much shuteye they actually get. It’s worth noting, though, that this exclusively respiratory approach is still considered experimental and Nyx still has to conduct a few at-home tests before bringing the shirt to market next year, hopefully for less than $100. Until then, we’ll just keep tossing and turning in our Spider Man jammies. Stroll past the break for an appropriately soporific video.

Paralyzed man can stand and walk again, thanks to spinal implant

Here’s an amazing story to end your week on a high note: a 25-year-old paraplegic is now walking again, thanks to a groundbreaking procedure developed by neuroscientists at the University of Louisville, UCLA and Cal Tech. The Oregon man, Rob Summers, was paralyzed below the chest in 2006, after getting hit by a speeding car. This week, however, doctors announced that Summers can now stand up on his own and remain standing for up to four minutes. With the help of a special harness, he can even take steps on a treadmill and can move his lower extremities for the first time in years. It was all made possible by a spinal implant that emits small pulses of electricity, designed to replicate signals that the brain usually sends to coordinate movement. Prior to receiving the implant in 2009, Summers underwent two years of training on a treadmill, with a harness supporting his weight and researchers moving his legs. This week’s breakthrough comes after 30 years of research, though scientists acknowledge that this brand of epidural stimulation still needs to be tested on a broader sample of subjects before any definitive conclusions can be drawn. Summers, meanwhile, seems understandably elated. “This procedure has completely changed my life,” the former baseball player said. “To be able to pick up my foot and step down again was unbelievable, but beyond all of that my sense of well-being has changed.” We can only imagine.

Phone Oximeter saves lives, puts Journey’s lawyers on red alert (video)

We’ll be honest with you, we don’t know a lot about marketing healthcare devices to everyday people, so perhaps posting a goofy YouTube video with some re-written classic rock songs is standard practice in the industry. Whatever the case, the University of British Columbia’s Electrical & Computer Engineering in Medicine team managed to bring its Phone Oximeter to our attention, and all said, this could be a handy little device for monitoring vitals outside a hospital setting. The meter hooks up to a smartphone — an iPhone for trials, but we’re told it works with Android, Windows, and others — displaying the wearer’s blood oxygen level and heart and respiratory rates, and transmitting the readings to the hospital. The department has already done some field testing with the system, trying it out at the Vancouver General Hospital and bringing it to Uganda, where low cost medical devices and Journey spoofs are in high demand. Video probably only meant for its creators’ friends and family after the break.

[Thanks, Walter]
