Sensual Meditation

The human being is linked by his/her receptors, the senses, to the unlimited which surrounds and composes him/her. By developing one is sensuality, one develops one is capability to feel connected with the unlimited, to feel countless oneself.

Sensual Meditation is the “instruction manual” given to us to teach us how to master the balancing possibilities within the brain, by those best placed to know, those who designed the human being.

Allowing one to deprogram the Judeo~Christian inhibitions of guilt, while at the same time not falling into the ethereal mysticisms of the Eastern teachings, Sensual Meditation allows the human to discover his/her body and especially to learn how to use it to enjoy sounds, colors, smells, tastes, caresses, and mainly a sexuality felt with all one is senses, so as to knowledge the cosmic orgasm, infinite and absolute, which illuminates the mind by linking the one who reaches it with the universes he/she is composed of and composes.

Somewhere does airliner transporter level with strange sports venues?

North Carolina and Michigan State on the flight deck of the USS Carl Vinson is undoubtedly the strangest venue for any college basketball sport, but it is not the most uncommon location ever for a sporting event.

TENNIS ON A HELIPAD AT 700 FEET IN THE AIR: The most memorable points Andre Agassi and Roger Federer ever played against one another didn't come at Wimbledon, the U.S. Open or any other Grand Slam. None of that compared to the sight of the two tennis superstars trading ground strokes 700 feet above Dubai's Jumeirah beach in a February 2005 exhibition on the helipad on the roof of the seven-star Burj Al Arab hotel.

THE GREAT WALL MARATHON 26.2 MILES: Hitting the wall isn't just a figure of speech at this grueling annual marathon. A quarter of the scenic 26.2-mile route takes place on China's famed Great Wall itself, and every sprinter must climb about 3,800 stone steps to arrive at the terminate line. The line record belongs to Spaniard Salvador Calvo, who won the 2007 race in 3 hours, 23 minutes, 10 seconds.

THE CARRIER CLASSIC: Michigan State and North Carolina will pay tribute to the military by playing a basketball game on an aircraft carrier on Veteran's Day in San Diego. The two teams will don camouflage jerseys with U.S.A. on the back of them, and President Obama and thousands of military personnel will be in the viewers. If it's sunny out, the game will take place on the flight deck. If not, it will move a level below into the air plane hangar.

GOLF ON GLACIERS: Golf is hard enough in picturesque 70-degree weather, so imagine how much more difficult it is when you introduce arctic conditions. That's the challenge each March in Greenland at the World Ice Golf Championships, which is played with a fluorescent orange ball and with glaciers and icebergs replacing sand traps and water as hazards.

THE BOYS OF WINTER: The popularity of hockey in outdoor football stadiums has steadily increased since Spartan Stadium hosted Michigan and Michigan State in 2001, but the signature event has become the NHL's Winter Classic held annually on New Year's Day. And no Winter Classic has piqued the interest of fans quite as much as the sight of the Philadelphia Flyers and Boston Bruins squaring off on the field and famed Fenway Park in 2010. Bruins fans went home satisfied: Their team won 2-1 in overtime.

TWO TEAMS, ONE END ZONE: A football game between Northwestern and Illinois at Wrigley Field seemed like a natural fit in 2010, but organizers failed to take into account the lack of space between the back of one end zone and the ivy-covered outfield wall. As a result, only the other end zone could be used for offense due to safety concerns, an embarrassing gaffe for the Big Ten but one that also made the game memorable.

THE WNBA TAKES CENTER STAGE: Kicked out of Madison Square Garden as a result of the 2004 Republican National Convention, the New York Liberty seized the opportunity to find a new venue that would bring some rare mainstream attention to the WNBA. They hosted the Detroit Shock at historic Radio City Music Hall, a venue that was especially unusual because seating there allowed fans to watch the game from only one side of the court.

KING OF GRASS VS. KING OF CLAY: The above image is not a trick. Tennis stars Roger Federer and Rafael Nadal really did play a 2007 exhibition match in Mallorca, Spain, on a customized half-clay, half-grass court designed to determine which of the two players was the best all-surface player. Nadal won a tightly contested three-set match much to the delight of the Spanish fans in the crowd.

SQUASH AT GRAND CENTRAL: How do you make one of the Professional Squash Association's most significant events more attractive to spectators? Bring it to the masses. The J.P. Morgan Tournament of Champions is annually held at New York City's Grand Central Terminal in a specially constructed four-walled glass court inside Vanderbilt Hall.

DUEL IN THE DESERT: The Carrier Classic isn't the only outdoor basketball game in recent years. The Suns and Nuggets played the first outdoor game in modern NBA history in 2008 at Indian Wells Tennis Center in California, a 77-72 Denver victory marred by poor shooting, gusty winds and frigid desert temperatures.

NHL YEARLY WINTER CLASSIC: In 2001, the Michigan State hockey team put a unique twist on their game alongside in-state rival Michigan by hosting the game inside their open-air football stadium. Noting the popularity the game generated, the National Hockey League borrowed the idea and now holds the yearly Winter Classic every New Year’s Day. Last year’s game took place inside Boston’s Fenway Park (home of the Red Sox) and featured the Boston Bruins beating the Philadelphia Flyers 2-1 in overtime.

Bollywood Megastar Shah Rukh Khan votes for Sundarbans

Shah Rukh Khan & other stars from the Indian & Bangladeshi show business world will perform at the Army Stadium in Dhaka on Friday, December 10, as part of a campaign to help the Sundarbans become one of the Official New7Wonders of Nature. Khan will vote live on stage & he hopes that this will motivate people to follow his example & support the Sundarbans campaign.


The Sundarbans is the largest tidal mangrove forest in the world. The name Sundarban means "beautiful forest" in the Bengali language.

Shah Rukh Khan is a Bollywood actor, film producer & television host. The Government of India honoured him with the Padma Shri Award in 2005 for his contribution to Indian Cinema.

The wonderful world wide Sundarbans mangrove

Some images of world's largest  Mangrove of Sundarbans

Is there anything that the humble mangrove cannot do? Along with being an important source of food & fuel, mangrove forests provide wood for building houses & ships because of its firmness & resistance to rot. Mangrove forests also make a significant contribution to the preservation of the environment by preventing coastline erosion caused by waves & currents.

But there's more. Mangrove forests absorb carbon dioxide & keep it locked away in the soil, & they offer a natural habitat for crabs, shrimps & waterbirds.

From Africa to Asia to Oceania to the Americas to the Middle East, you'll find mangroves. & two of the 28 Official Finalists in the New7Wonders of Nature place considerable emphasis on their mangrove forests: The Sundarbans & Bu Tinah Island.

The Mangrove Action Project a non-governmental organization run by a global network with the goal of saving mangroves works to raise awareness of the trees & their benefits. Part of its mission is to point out that the mangrove is increasingly threatened by coastal development.

Mindful of the role of the mangrove, the Environment Agency Abu Dhabi (EAD) is promoting the tree as a buffer against extreme weather events & as a nursery to the emirate's fish stocks. Its most recent mangrove project took place in February this year, when it planted 800,000 trees. Thabit Al Abdessalaam, Director of Biodiversity Management Sector at EAD, said: "The mangrove plays an integral role in the marine ecosystem, providing a habitat for aquatic & terrestrial fauna & flora, as well as offsetting carbon emissions which help reduce the effects of climate change. It is essential that each one of us assume responsibility for the conservation of this species, as it is a treasured part of our natural heritage."

New7Wonders launches SMS voting in Bangladesh: government targets 1 billion votes for Sundarbans

Bangladesh is one of the world leaders in providing mobile telephone access for it's large population, & many of the country's mobile companies are pioneers in this field. In an advanced partnership with New7Wonders, the leading mobile provider, Teletalk Bangladesh Limited, in corporation with the nation's other mobile companies, has set up a generally available SMS voting system for the New7Wonders of Nature. Voters from Bangladesh can now contribute by sending a SMS from any mobile phone anywhere in the country. Voting for Sundarbans just needs the two letters "SB" sent to 16333, & each SMS vote counts as one vote for the Sundarbans. Voting is also possible for the remaining 27 Finalists, & each SMS vote costs BDT2.

Announcing the launch of the New7Wonders of Nature SMS voting in Bangladesh, Environment Minister Dr. Hasan Mahmud said, "There are at least 50 million active mobile SIM cards in the country, & if 20 SMS were sent through each SIM card, the Sundarbans would get one billion SMS votes to its credit".

Welcoming the launch, New7Wonders Director Jean-Paul de la Fuente says, "Bangladesh is a strong contributor in the New7Wonders of Nature campaign, & as I have viewed first-hand, Bangladeshis are excited texters so I am sure they will show their SMS support for Sundarbans in the coming weeks & months." He continues, "This partnership is unique as it brings together challenging mobile companies, with the inspiration & support of the government & the regulator, all working in unison for the national awareness & to ensure maximum access to the New7Wonders of Nature campaign for the extremely mobile-enabled Bangladesh population."












The Sundarbans delta, at the mouth of the Ganges river, is the largest mangrove forest in the world, spreading across parts of Bangladesh and West Bengal, India. The Sundarbans features a complex network of tidal waterways, mudflats and small islands of salt-tolerant mangrove forests. The area is known for its wide range of fauna, with the Royal Bengal tiger being the most famous, but also including many birds, spotted deer, crocodiles and snakes.

Does boyfriend love you? Find his method for clues

Wifey just got a new hair cut what do you guys think? I love it, Ashton Kutcher tweeted in 2009, along with a photo of a mo-hawked Demi Moore, circa G.I. Jane.

I have the buzzer ready baby, she responded.
Im just playing baby but I think youd look great with that cut.
Thank you love. How bout I shave your initials into my head.

If youre analyzing the couples relationship by their tweets (and many people are these days) dont look at the subject matter. Look at the pronouns.

James W. Pennebaker, a psychology professor at the University of Austin at Texas, has developed a method for measuring the compatibility of a couple based on words like I, you, me, & about 180 others.

He calls them function words - those small, often ignored pronouns (she, he, I), prepositions, (with, but) & articles (a, the)-that he believes are something of a window to the soul.

The way two people use function words with each other is a reflection of the patterns going on their mind, explains Pennebaker, who penned a book on the subject called, The Secret Life of Pronouns. Its a subconscious way of seeing if two people are on the same page.

While context, geographical & cultural backgrounds play a role in the way people carry on a conversation, what Pennebakers really looking out for is whether two people are adapting each others speech patterns. The more they mimic each other in the way they use words, the more sympatico they are.

In a series of studies, he found that when two people match function words in a conversation with each other-be it on email, Facebook, Twitter, or face to face- they are subconsciously connecting on a deeper level.

Its a sign theyre connecting, theyre thinking alike, he says.

In one study of a group of speed daters, Pennebaker found that those who used function words in a similar manner were three times as likely to pick each other for a date. Comparing language in writing is just as revealing. In looking at the letters of married poets Sylva Plath & Ted Hughes, Pennebaker found their language patterns matched up less & less as their marriage dissolved.

But its not just about love. Word match-ups are also a sign that two people fight well together. Based on Pennebakers analysis of Rosie ODonnell & Elizabeth Hasselbacks arguments on The View they match pound for pound on speech patterns, though not at all on beliefs.

Its more telling about whether the two people are paying attention to one another, & how engaged they are with one another, explains Pennebaker. If two people are really connected theyre having the same conversation.

Want to use his theory on your own relationships? Take a look at a recent email exchange . Do you start sentences the same way? Do you both use a lot of prepositions in your explanations?

If interpreting your romantic email exchanges grammatically feels a little too hyper-analytical (re: not cool) let Pennebaker do it for you. On his website, secretlifeofpronouns.com, you can actually copy & paste an email, Twitter or IM exchange & have it automatically analyzed for compatibility.

For my own experiment, I entered the Twitter exchange at the top of this post into Pennebakers grammar calculator. The results: Demi & Ashton are not very compatible. Their haircut banter scored a .59 on a scale of .100. Thats far below average, according to the site, which gives an average score of .84 for most online exchanges.

To be fair, my language sample was small (it works better if you enter at least a couple hundred words for each person) & the way people write on Twitter isnt exactly a good measure of how they write or speak anywhere else.

But lets take their low score at face value. Back in 2009, when this Twitter exchange transpired, their language wasnt overlapping, & by Pennebakers logic, that means they werent thinking alike, which really means they werent paying attention to each other. Most relationship experts would recommend a little affection as an antidote, a reminder of those three littler words, I love you. But if you ask Pennebaker, all that really matters is the I & You.

Third Series of Paranormal Activity Hits UK Box Office

It is debuting that at number one with takings of £55m. This horror story is based on Unexplained supernatural theme like "Forth Kind", which purports to present discovered footage of things going bump in the night, is also at the top of the US film charts.

By pre-empting the Hallowe'en weekend, it sneaks ahead of on several other horror releases. Due out this week are Demons Never Die, The Silence & a re-release of 1984 comedy classic Ghostbusters. But they face strong competition from Stephen Spielberg's blockbuster retelling of Tintin, US civil rights drama The Help early release.

Paranormal Activity 3 is strong debut knocked spy spoof Johnny English: Reborn down to second place in this week's chart.

It made £2 million over the weekend, putting it comfortably above the star-studded disaster movie Contagion, which was a new entry at number three. But on a screen-by-screen basis, little separated the two films.

Rowan Atkinson's secret agent took an average of £3,718 on each of the 552 screens it was showing on, while Contagion's receipts were £3,711 on 398 screens.

The only other new entry in this week's chart was literary adaptation We Need To Talk About Kevin, which took £492,297 to land in seventh place.

Meanwhile, The Smurfs is the longest-running hit on the chart, hanging on to 14th place in its 16th week of release, with total box office takings of £16.7 million.

Thailand Floods Could Last-VI-More-Weeks

Thailand's catastrophic floods may take up to six-weeks to recede, the prime minister said Saturday, as residents living in Bangkok's outskirts sloshed through waist high waters in some areas & the human toll from the crisis nationwide rose to 356 dead & more than 110,000 displaced.

Water bearing down on the capital from the north began spilling through Bangkok's outer districts on Friday & continued creeping in on Saturday. So far, however, most of the metropolis of 9 million people has escaped unharmed, & its two airports are operating normally.

Bangkokians are girding for the worst, though, after Prime Minister Yingluck Shinawatra this week urged all residents to move valuables to higher ground. A mild panic prompted a run on grocery stores, with many running out of bottled water. A Thai company that distributes drinking water across the city sent out an SMS to customers announcing deliveries had been halted because of the crisis.

Miracle of creator: Man surfs on backside of a big white shark !

Doug Niblack was surfing when he hit something hard & found himself footing on the back of a shark.

[It was stunning frightening just seeing the shape appear out of nothing & just being under me, he said. Looking down at his feet Doug could see the shark's dorsal fin in front of him & a full 10ft of the shark's back. & the fin coming out of the water. It was just like the movie.]

Huge comet crash closely avoided in 1883

A huge comet closely missed hitting the Earth when it passed within 5,000 miles of us in 1883.

Astronomers have been examining a photograph of the comet taken in 1883 by Mexican astronomer Jose Banilla. At the time it was hailed as the first photograph of a UFO. The object would have been 8 times the mass of Haley's comet & would have wrought untold devastation if it had hit us, may be destroy mankind!

But now scientists from the Universidad Nacional Autonoma de Mexico believe it could have been a massive comet that came close to hitting the Earth with a similar mass to the object that killed the dinosaurs.

Mexican scientists believe this photograph taken in 1883 shows a comet that came shut to hitting the earth.

Using the time that it took the object to cross the sun combined with the location of Bonilla's observatory, the report calculated that the object would be at most 8,000km away, & possibly much less.
'The only bodies in the Solar System which are enclosed by a bright murkiness are the comets, so it is accurate to suppose that the objects seen by Bonilla were small comets, believed the scientists.

As well as being shockingly close to earth, the scientists think that the comet could have had the same group as the object that wiped out the dinosaurs eight times the mass of Halley's comet.
The report's claims have been questioned, though as a comet breaking up so shut to earth should have resulted in a meteor shower, & no astronomers detected one.

A New universal charging system for electric vehicles

The worldwide infrastructure of charging stations for electric vehicles[EV] may seem overwhelming, you know what would make it even more challenging? If each station had to separately cater to each make of EV on the road think of how many different styles of mobile phone chargers are currently out there, for instance, & then picture that applying to cars. Fortunately a consortium of automakers has developed the Combined Charging System that will allow any one vehicle to charge its batteries using a variety of different charging methods.

The system was developed by Germany's Audi, BMW, Daimler, Porsche, & Volkswagen, working in partnership with America's Ford & General Motors.

It consists of a single interface on the vehicle, which is compatible with methods such as one-phase AC-charging, fast three-phase AC/DC charging at home & ultra~fast DC charging at public stations. This is intended to make EV development a less complex process, as vehicles won't need to incorporate multiple inlets, nor will their drivers need to seek out specific charging stations. Instead, all electric vehicles will be able to recharge at all stations.

The technology also features a charging communication system, along with an electrical & safety architecture, that will work with any vehicle using the system.

The Combined Charging System is being demonstrated at the 15th International VDI Congress & Exhibition [Electronic Systems for Motor Vehicles], which takes place this Wednesday & Thursday in Baden~Baden. It should be ready for deployment in the auto industry by the middle of next year.

New innovation is coming up: The Particular Brain Fold That Helps People Distinguish between Imagination and Reality

Did you actually open the refrigerator a few minutes ago, or were you just thinking about it & imagined that you did? If you can remember correctly, you might have an extra fold in your brain.

A fold in the front brain called the paracingulate sulcus, or PCS, can apparently help people more accurately remember whether something was imagined or really happened, or which person actually said something. It's one of the final structural folds to develop before birth, & its size varies greatly in the general population, according to researchers at the University of Cambridge. People with the fold were significantly better at memory tasks than people without the fold, the researchers say.

The study, which was published in the Journal of Neuroscience, involved 53 healthy adult volunteers with no reported history of cognitive difficulties, according to a Cambridge news release. & everyone thought they had a good memory before the tests.

Participants were chosen based on MRI scans that showed a clear presence or absence of the PCS fold. Then they were presented with word pairs & half-pairs — like “Laurel & Hardy” or “Laurel & ?” In the second test, they were asked to imagine the other word, & then either they or the study leader actually said the word aloud.

Then they had a memory test, where they tried to remember whether they had actually seen the second word or just imagined it, & which person said the word out loud, Cambridge says. People with a PCS remembered correctly a lot more often.

This work has implications for some mental disorders like schizophrenia, in which the line between reality & imagination is unclear to the patient. In other studies, schizophrenic patients reportedly have had reduced PCS areas, according to Jon Simons of Cambridge’s Experimental Psychology department & Behavioural & Clinical Neuroscience Institute.

What to do about this isn’t clear — because the fold happens so shortly before birth, it’s not something that can be physically changed. But understanding the PCS’ role in memory & reality perception could have some impact on drug treatments for mental disorders.

Apple founder, Steve Jobs, passed away on Wednesday [October 5]

Apple founder, Steve Jobs, passed away on Wednesday [October 5] at the age of 56, succumbing to pancreatic cancer.

The company announced his death this week. However, did not give any specific cause.

We are deeply saddened to announce that Steve Jobs passed away today, the company said in a brief statement. Steve's brilliance, passion & energy were the source of countless innovations that enrich & improve all of our lives. The world is immeasurably better because of Steve.

Jobs had been diagnosed with a rare form of pancreatic cancer called pancreatic neuroendocrine cancer. While those suffering can live as long as 20 years with the disease, it obviously wasn't the case with the Apple visionary.

His cancer eventually spread to his liver, so he was forced to have a liver transplant in 2009 & took an extended medical leave from Apple last January.

Even after a liver transplant, the cancer can recur, which may have been what happened in Jobs' case.

Jobs started Apple with a high school friend in a Silicon Valley garage in 1976, but 10 years later, he was forced out of the company. Eventually, in 1997, he returned to rescue the company he helped build. During his second stint, it grew into the most valuable technology company in the world with a market value of $351 billion.

He's responsible for inventing & masterfully marketing ever-sleeker gadgets that transformed everyday technology, from the personal computer to the iPod & iPhone.

Jobs is survived by his wife Laurene, whom he has two daughters & a son with. He also has another daughter from a previous relationship.

Young Steve Jobs
His death became a trending topic on Wednesday, drawing actions from Apple fans, as well as celebrities & political figures.

Steve was among the greatest of American innovators -- brave enough to think differently, bold enough to believe he could change the world, & talented enough to do it, said President Obama in a statement. Steve was fond of saying that he lived every day like it was his last. Because he did, he transformed our lives, redefined entire industries, & achieved one of the rarest feats in human history: he changed the way each of us sees the world.

I'm truly saddened to learn of Steve Jobs' death, said Microsoft founder, Bill Gates. Melinda & I extend our sincere condolences to his family & friends, & to everyone Steve has touched through his work. Steve & I first met nearly 30 years ago, & have been colleagues, competitors & friends over the course of more than half our lives. The world rarely sees someone who has had the profound impact Steve has had, the effects of which will be felt for many generations to come. For those of us lucky enough to get to work with him, it's been an insanely great honor. I will miss Steve immensely.

The Future Arrives Next Week

TRSF, an anthology of original science fiction stories, is in stores on October 4.



Back in May, we told you that Technology Review was planning to publish an collection of all-new near-future science fiction stories, grounded in the kinds of technological breakthroughs that we report on here every day. Now the TRSF is almost here—you can preorder a copy today, or wait till it goes on sale on newstands next Tuesday. (Digital editions will be available soon after.)

We've got an amazing selection of writers from around the world, including legends like Pat Cadigan & Joe Haldeman, current stars like Cory Doctorow & Elizabeth Bear, & emerging talents like Vandana Singh & Ma Boyong (this is Boyong's first time appearing in English).

For a full rundown of authors,visit the TRSF microsite, which also has a video describing how the cover of the TRSF was created by the iconic science fiction illustrator, Chris Foss. This is Foss's first major U.S. commission in recent years, & we've also reproduced six of his classic covers within the pages of the TRSF.

The 12 stories in the TRSF range from a light-hearted look at the (almost certainly) inevitable future of kitchen appliances talking to each other, to a more worrisome tale of a researcher fighting her company's attempts to turn therapeutic tool into a mind control technology. They all fulfill the goal of the TRSF: to showcase thought provoking science fiction that explores some of the implications of technological developments in ways that journalism cannot.

Kinect Project Merges Real & Virtual Worlds

[ Multimedia ]
High Fidelity 3-D Images Created Using KinectFusion.


New software turns the Kinect into a cheap 3-D scanner—opening up applications ranging from crime fighting to interior design.

Microsoft's Kinect Xbox controller, which lets gamers control on-screen action with their body movements, has been adapted in hundreds of interesting, useful, & occasionally bizarre ways since its release in November 2010. It's been used for robotic vision & automated home lighting. It's helped wheelchair users with their shopping. Yet these uses could look like child's play compared to the new 3-D modeling capabilities Microsoft has developed for the Kinect.

KinectFusion, a research project that lets users generate high-quality 3-D models in real time using a standard $100 Kinect, was the star of the show at Microsoft Research's 20th anniversary event held this week at its European headquarters in Cambridge, U.K. KinectFusion also includes a realistic physics engine that allows scanned objects to be manipulated in realistic ways.

The technology allows objects, people, & entire rooms to be scanned in 3-D at a fraction of the normal cost. Imagine true-to-life avatars & objects being imported into virtual environments. Or a crime scene that can be re-created within seconds. Visualizing a new sofa in your living room & other virtual interior design tricks could become remarkably simple.

"KinectFusion is a platform that allows us to rethink the ways that computers see the world," says project leader Shahram Izadi. "We have outlined some ways it could be used, but I expect there are a whole host of future applications waiting to be discovered."

3-D scanners already exist, but none of them approach KinectFusion in ease of use & speed, & even desktop versions cost around $3,000.

"In the same way that products like Microsoft Office democratized the creation of 2-D documents, with KinectFusion anyone can create 3-D content just by picking up a Kinect & scanning something in," says team member Steve Hodges.

The first public unveiling of KinectFusion at the SIGGRAPH conference in Vancouver in August triggered huge excitement. Details of how it works will be revealed in papers presented next month at the UIST Symposium in Santa Barbara, California, & ISMAR in Basel, Switzerland.

The Kinect projects a laser dot pattern into a scene & looks for distortions using an infrared camera, a technique called structured light depth sensing. This generates a "point cloud" of distances to the camera that the Kinect uses to perceive & identify objects & gestures in real time.

A KinectFusion user waves a Kinect around a scene or object. An algorithm called iterative closest point (ICP) is used to merge data from the snapshots being taken at 30 frames per second into an ever-more-detailed 3-D representation. ICP is also used to track the position & orientation of the camera by comparing new frame data with previous frames & the composite merged representation. The team describes the use of a standard computer graphics processing unit for both camera tracking & image generation as a major innovation.

While KinectFusion is generating a buzz, it is still an ongoing research project. Microsoft has not disclosed plans to release any products using the technology, or versions of the software that power the system.

"It's just stunning," says Christian Holz, of the Hasso Plattner Institute at the University of Potsdam, in Germany, who previously worked on a project that used Kinect at Microsoft Research in Redmond, Washington. "It's going to make 3-D creation available to a much wider range of people. The fact that it can not only model the real-world environment in mind-blowing fidelity, but also use the model to simulate realistic physics on top of that, opens up the possibility of a vast number of applications."

Easy Way to Boost Battery Storage

Battery binder: This microscopy image shows a silicon electrode before charging (left) and after 32 cycles. A new binder keeps the particles close together.

A stretchy binder material that's compatible with existing factories could help electric cars & portable electronics go 30 percent longer. By Katherine Bourzac

Lithium-ion battery electrodes bound together by a new highly conductive material have a much greater storage capacity—a development that could eventually increase the range of electric cars & the life of smart-phone batteries without increasing their cost. Unlike many high-capacity electrodes developed over the last few years, these can be made using the equipment already found in today's battery factories.

The key is a stretchy, highly conductive polymer binder that can be used to hold together silicon, tin, & other materials that can store a lot of energy but that are ordinarily unstable. Researchers at the Lawrence Berkeley National Laboratory painstakingly engineered this new polymer binder & used it to make a silicon anode for a rechargeable lithium-ion battery with a storage capacity 30 percent greater than those on the market today. It's also more stable over time than previously developed electrodes.

When a lithium-ion battery is charged, lithium ions are taken up by one of the electrodes, called the anode. The more lithium the anode can hold, the more energy the battery can store. Silicon is one of the most promising anode materials: it can store 10 times more lithium than graphite, which is used to make the anodes in the lithium-ion batteries on the market today. "Graphite soaks up lithium like a sponge, holding its shape, but silicon is more like a balloon," says Gao Liu, a researcher at the Berkeley Lab's Environmental Energy Technologies Division.

However, because the silicon anodes swell & shrink, changing in volume by three or four times as they're charged & discharged, the capacity of the battery fades over time. "After a few rounds of charge & discharge, pretty soon the silicon particles are not in touch with each other," which means the anode can't conduct electricity, says Liu.

One approach to the problem is to structure these anodes in a totally different way, for example growing shaggy arrays of silicon nanowires that can bend, swell, & move around as lithium enters & exits. This approach is being commercialized by Amprius, a startup in Palo Alto, California. But growing nanowires requires new processes that aren't normally used in battery manufacturing.

Today's anodes are made by painting a solvent-based slurry of graphite particles held together with a binder, a simple process that keeps costs low. The Berkeley researchers believe the key to making new battery materials like silicon work is to stick with this manufacturing process. That meant coming up with a rubbery binder that would stick to silicon particles, remain highly conductive in the harsh environment of the anode, & stretch & contract as the anode swells & deflates.

Most work on advanced batteries has focused on the active materials, but "we have pushed these materials to the limit," says Yury Gogotsi, professor of materials science & engineering at Drexel University. "Now what's limiting us are the binders."

Reading through papers on silicon battery binders, Liu noticed that researchers were making "fatal mistakes"—choosing polymers that lose their conductivity in the kinds of conditions found in an anode, for example. He worked with theoretical chemists to come up with a list of polymers with the right electrical properties for the job. Once they found one, they altered it to make it much stickier. Once they developed & characterized this new material, they were able to make silicon anodes using conventional processes, & test them in batteries.

The Berkeley group's anodes have been tested in over 650 charging cycles. They maintain a storage capacity of 1,400 milliamp hours per gram—much greater than the 300 or so stored by conventional anodes. Full batteries incorporating the anodes store about 30 percent more total energy than a commercial lithium-ion battery. Typically, battery capacity increases by about 5 percent a year, Liu notes. He says they've tested the binder in other battery anodes, including those made of tin, that have similar potential & problems, & that it should work for any such materials.

The storage capacity of these batteries is nearly as good as those made from pure silicon nanowires with no binders, says Yi Cui, professor of materials science & engineering at Stanford & one of the founders of Amprius. That's impressive, he says, considering that the binder doesn't store any lithium.

Liu's group is now collaborating with researchers at 3M on the anode research. 3M is scaling up production of silicon-based battery materials designed to not expand quite so much during charging, says Kevin Eberman, who is developing battery materials products at 3M Electronics in St. Paul, Minnesota. But to make them work, a good binder is key. The company is providing the Berkeley group with materials to test. Liu says the Berkeley group has patented the binders, & is in talks with a few companies about ways to commercialize them.
