London (CNN) — Imagine if you could paint a working light switch directly onto your wall, without any need for sockets, cables or wiring.

A group of students from the Royal College of Art (RCA) in London has made that possible by creating electrically conductive paint.

The paint acts as a form of liquid wiring. Unlike conventional wires, it can be applied to almost any surface, including paper, plastic, metal and even fabric.

The product has the appearance and consistency of runny marmite, but dries quickly when exposed to the air. Its inventors, RCA graduates Isabel Lizardi, Matt Johnson, Bibi Nelson and Becky Pilditch, call their creation “Bare Paint.” While they don’t claim to be the first group to have invented a conductive ink, they are pioneering new ways it can be used.

“We started this project in earnest in 2009,” says Matt Johnson. “We were originally interested in trying to apply electronics to the skin … so we arrived at this idea of applying them as a coating and eventually we got this idea of a conductive paint.”

The team began by investigating how electronics were being used in the body.

“In 2008 — and probably still today — there was a lot of work around electronic textiles,” says Johnson. “And though we really liked the idea of having a jumper (a piece of clothing) that has some intelligence in it, we didn’t like that it was so bulky and that once you took it off the functionality disappeared.”

Around the same time there was a lot of “extreme work” being done by people who were injecting electronics beneath the skin. For their final project, the RCA students began work on making something less intrusive, looking for a substance that could be painted onto the body. Eventually, says Johnson, “that idea transformed into the material we have now, which is very safe though it’s not specifically intended for the body anymore.”

Read: Designs that will define our future

After graduating from college, the team collaborated on a video for DJ and producer Calvin Harris. The resulting project was the “Humanthesizer,” a performance which literally brought the paint to life, with dancers whose movements triggered audio loops from Harris’s song “Ready for the Weekend.”

“Making a new material was a bit daunting for four designers,” says Johnson. The team’s solution was not to return to school to study chemistry for four years. Instead, they simply went on Wikipedia. According to Johnson, the online encyclopedia provided them with almost everything they needed to know about crafting conductive materials.

Once the paint’s formula was finalized, co-creator Isabel Lizardi says the team began to consider how it might be applied to real-world products. The first thing they launched was the paint in its raw form, which they made available to other garden-shed inventors.

Today, Bare Paint jars and pens are sold on the Internet and stocked by Radio Shack electronics stores across the United States. Projects being done by Bare Paint users include everything from interactive color wheels to homemade electric toys.

Johnson says that conductive paint opens up an enormous range of creative opportunities. As conductive paint becomes increasingly common, we can look forward to a future where billboards talk back, walls are interactive, and greeting cards come to life in our very hands.

“Devices no longer have to look high tech to be high tech,” Johnson says. “Our goal is to put interactivity onto objects you don’t expect.”

Family may exhume Todd for U.S. autopsy

(CNN) — The parents of American Shane Todd, found hanging in his Singapore apartment last June, tell CNN they may exhume their son’s body to conduct an autopsy in the United States.

Todd’s mother Mary says an exhumation may be the only way to prove “for sure” the family’s contention that he was murdered.

The Todds walked out of the Singapore inquiry into their son’s death earlier this week, saying, “We’ve lost faith in the process” and Singapore’s inquiry process was “pre-determined” to conclude their son’s death was a suicide, and that police and investigators never considered evidence that may suggest Todd was murdered.

“We told the police at the very beginning. We talked to Shane every week for three months at least, all the way up to June when he passed away, (and he said) that he was in fear for his life,” Todd’s father Rick told CNN. “You would think they would look into it. But none of that happened.”

The inquiry into the death of Todd, found hanging in his Singapore apartment on June 24, comes after Singapore’s medical examiner concluded that Todd committed suicide. State attorneys said during the hearing that Todd’s laptop shows he accessed suicide-related web pages in the months before his death, with a search in March on how to tie a hangman’s noose. But Todd’s parents — who had flown from their home in Montana to attend the hearings — claimed there was evidence that his death was a homicide.

The Todds claim their son was murdered because of sensitive knowledge he had of a project using gallium nitride (GaN) between the Institute of Microelectronics (IME) — a Singapore government-backed research agency — and the Chinese telecom giant Huawei.

GaN is material that can withstand high temperatures and can be used in power amplifiers with a range of applications from light emitting displays to radar communications.

Documents found on Todd’s laptop after his death reportedly indicate IME may have had plans with Chinese telecom giant Huawei to co-develop an amplifier using GaN. Such a device could have both military as well as civilian uses. The 31-year-old Todd had been working for 18 months at IME when he decided to quit his job and return home to the United States shortly before his death.

Employees of IME have testified that there were several meetings held with Huawei, including a meeting with their senior level employees that Todd attended, but both IME and Huawei assert no project agreement was concluded, according to testimony.

Patrick Lo, deputy executive director of research at IME and Todd’s supervisor, testified that his agency does not conduct any classified military research.

The Todds say they have evidence to show their son had been instructed to hand copy a GaN “recipe” or formula from a U.S. vendor where Todd had been sent for training.

The family says he had been left alone in a room to hand copy formulas, and say evidence from Shane’s computer shows he had handwritten “highly sensitive recipes.”

Lo denied in court that he had instructed Todd to hand copy recipes and said hand copied recipes would be inaccurate and therefore “useless.”

The Todds stood up in the middle of the inquest proceedings Tuesday and walked out in objection to a witness they were unfamiliar with — a friend and former work colleague of their son’s who testified he’d had a beer with him the night before Todd was found hanging on June 24.

“We’re getting sprung stuff at the last moment,” Rick Todd said outside court. He said the state had given them no prior notice of the witness Frenchman Luis Alejandro Andro Montes.

The Todds said they had been “told from the beginning that this will be honest and open” and pointed out that their own lawyers had just hours before been chastised by Singapore’s judge Chay Yuen Fatt for introducing last-minute documents.

Singapore Senior Counsel Tai Wei Shyong referenced Montes in his May 13 opening statement and at that same time said the state would try to bring Montes in as a witness.

Just hours before, a key witness for the Todd family, American medical examiner Dr Edward Adelstein, retracted his original assertion that Shane Todd had been strangled by a cord and hanged. Testifying via video link, Adelstein agreed with other forensic pathologists in the case including two U.S. medical examiners, who reviewed the case at Singapore’s request, that there would need to be evidence of internal neck injuries if Todd had been “garroted.”

However, Adelstein continued to assert that Todd had been murdered and speculated that he had been killed and then hanged to make it look like suicide.

“I have to assume that people who know how to kill you can do it in a way that is difficult to detect,” Adelstein added.

He did not examine Todd’s body and came to his initial conclusions on the basis of photographs taken by the family just before the funeral and Singapore’s autopsy report.

His new opinions come after the family provided him with a series of photos obtained from Singapore police and forensic officials.

Questioned about the photos by a lawyer for the state, Adelstein admitted, “The cause of death is difficult for me to say.”

Forget what you know, next-gen consoles change everything

For the better part of a decade the video game landscape remained mostly unchanged, complacent in a sea of sequels, motion controls, and downloadable content.

It’s a generation that has lasted longer than any other before it, albeit for generally good reasons. And perhaps most impressive is that though their PC gaming counterparts have long since passed them by, these aging consoles are still able to render great-looking games.

So while the sun begins to set on what will go down as a pivotal generation for video games, we look ahead to see what owning a console will be like for the foreseeable future.

And then there were two
There’s no disrespect intended here toward Nintendo, but the next great console wars will be fought by two parties, not three. Sure, Nintendo beat everyone to the punch by releasing its next-generation console an entire year early, but the
Wii U just barely catches up to the prowess of what
PlayStation 3 and
Xbox 360 had been doing all along — at least from a graphical and technical standpoint.

By no means is this a death sentence, though. Nintendo is company that needs to find itself and reposition. However that plan might play out, it most likely will not consist of picking fights with PlayStation 4 or Xbox One.

Graphics won’t define next-gen
Eye candy made a big splash at the dawn of gaming’s previous generation. That will not be the case this time around — for the most part. Sure, Xbox One and PlayStation 4 have the graphical chops that are sure to impress anyone who hasn’t experienced a high-end graphics card for the past two years. But the dramatic jaw-dropping jump from standard definition to high definition that took place eight years ago will not happen again.

Instead, next-generation gaming will be defined through a multitude of variables. Gamers want to experience interactive software in ways they never thought were possible. Perhaps that lies in the heartbeat-sensing Kinect camera or game-screen-sharing features built into PlayStation 4.

However you choose to label it is irrelevant. Games need to evolve beyond regenerative health and compelling cinematics. They need to push the envelope in new directions. The hardware is here, and the talent is ready. These are the elements that will truly define “next-gen.”

Consoles aren’t just for gamers anymore
As much as you’d like to keep these machines for yourselves, electronics manufacturers really like it when consumers outside of their intended demographic begin to take interest. That’s what happens when the Wii finds itself in senior-citizen homes and at the gym.

This really shouldn’t come as much of a shock either, though. Consoles have been slowly mutating into the all-encompassing content distribution hubs they are now for years. The biggest push, as made evident by the Xbox One’s ambitious live TV integration (and Nintendo TVii’s not-so-successful launch), is the attempt to corner the crux of the living room experience. These consoles are being designed to be the very first thing you interact with the second you sit down on your couch.

This changing focus in audience will certainly alienate some core gamers, but the truth of the matter is that consoles are not just for gamers anymore. Want a box just for gaming? Go build one.

New and used games will blur, frustrate, and confuse
Trips to the local game shop will slowly begin to go away, and digital marketplaces will soon reign supreme. We feared the worst about how the ownership of software may become fuzzy and now those fears hold a bit more weight.

While we still don’t definitively understand how both Sony and Microsoft plan on proceeding, it’s clear that the fundamental concept of buying and selling used games will be changing forever. This also means that the very psychology of consumer behavior will also evolve. Borrowing a game might be a thing of the past. Sharing games seems highly unlikely. Microsoft has gone on record claiming that there will be a way to sell a used game, but don’t expect it to resemble anything you’re accustomed to.

But before you light the torches and sharpen your trusty pitchforks, think for a second and appreciate how long this novelty has lasted. Think about other industries that have flipped out over that naughty “sharing” word. It was inevitable.

Of course there are still plenty of details that need clarification, but the message is clear. Physical media is on its way out.

Gaming voyeurism is now a thing
Maybe I’m out of touch with this trend, but I don’t really understand the joy of watching someone else play a video game. While I know plenty of gamers who feel the exact same way, it’s also tough to ignore the budding content empires that have constructed business models around the notion.

Whether or not you asked for it, the next gaming console in your living room will allow you to record and edit a highlight reel of your very own gameplay and share it with the world. All that time you spent wasting away on Facebook, Reddit and Twitter? Well, now you can continue indulging while gaming.

Get used to the cloud
A console hooked up to the Internet is nothing new. But with the architecture of these machines, titles and firmware can be automatically updated without you having to lift a finger.

As for the cloud, game saves are just the tip of the iceberg. Heck, even current consoles can sync game saves. Cloud computing in the next generation of video games will take things to a totally different level. Beyond just access to saves, games will be able to be streamed and played the way you would watch a movie on Netflix. Sony has already said PS4 owners will be able to begin playing a game as it’s being downloaded, and Microsoft has acknowledged a similar technology.

Microsoft even hinted at potentially offloading some of the computing power that Xbox One games might require, opening the door to cloud expansion within a game.

Forget about backward compatibility
Regardless of whether it’s some sort of strategic spin or crafty wording, backward compatibility, at least at its core, is soon to become a thing of the past. We’re not yet privy to how Sony will deal with it (though we’re leaning toward a Gaikai-powered streaming option), but Microsoft has definitively stated it won’t be an option.

If you want to play last generation’s video games, then hold on to that last-generation console. Or, you could always fork over the cash it’ll cost you to download these throwback titles when they inevitably make their way to your platform of choice’s online store.

This is a feature I’m quick to criticize for there being a lack of, but have grown to ultimately accept. Sure, it prevents you from reselling an old console to put toward a new one, but we forget that the very inclusion of these innards in a future system would likely increase their price anyway.

James Martin/CNET)

We’re all in this together
One of the advantages of a connected console was made abundantly clear over the last eight years. The Internet has afforded console manufacturers the luxury of treating these machines as works in progress. Sure, this doesn’t exist without some frustrations or glitches, but ultimately I think the pros outweigh the cons.

And if there’s one thing we’ve learned with how vocal the gaming community can be, it’s that these companies are becoming very receptive to what we want — and that’s a good thing. It’s now almost impossible to get away with a policy that the masses reject because they’ll simply boycott and bombard it with negativity.

Gamers are the constituents of the industry in this ever-evolving relationship, and we vote with our dollar. Besides, console manufacturers want us on their side anyway. In reality, the next war won’t be fought with gamers and their hard-earned cash, but with the other box in the living room that’s competing for your attention — your cable box.

Tiny crystal flowers bloom in a beaker

The false-colored flowers bloom almost smaller than the naked eye can see.


(Credit:
Wim L. Noorduin, Harvard SEAS)

When you think of the word “crystal,” you think, perhaps, of wedges of quartz stone, ice crystals, and salt — not organic flowing forms or flowers. But by manipulating chemical gradients in a beaker of fluid, Harvard postdoctoral fellow Wim L. Noorduin has managed to control the growth of barium carbonate crystals to form very controlled sculptures of flowers, with petals, stems, and leaves.

How the crystal forms depends on the mixture of chemicals in a solution. As the chemical gradients react, the pH can change, causing the crystals to grow away from or toward the gradient, enabling Noorduin to coax the forms into leaves radiating outward, a ling, thin stem, or the petals of the flower head.

To create the crystals, the team from Harvard’s School of Engineering and Applied Sciences dissolved barium chloride and sodium silicate in a beaker of liquid. Carbon dioxide, naturally dissolving into the liquid, sets of a reaction that precipitates the formation of barium carbonate. Additionally, it lowers the pH balance immediately around the crystals, adding a layer of silica and allowing the crystals to continue to form.

The work, said Noorduin, is meant to enhance the understanding of self assembly, which could potentially revolutionize the manufacture of tiny electronics. “For at least 200 years, people have been intrigued by how complex shapes could have evolved in nature,” he said. “This work helps to demonstrate what’s possible just through environmental, chemical changes.”

The research paper, called “Rationally Designed Complex, Hierarchical Microarchitectures,” can be read online in the journal Science.

LG to demo bendable, unbreakable smartphone screen

LG Display is preparing to demonstrate a new, flexible smartphone panel that promises to be unbreakable.

The new screen is set to pop up at the Society for Information Display’s annual exhibition, Display Week 2013. The event, which showcases display products, is taking place this week in Vancouver, Canada.

The OLED (organic light-emitting diode) technology used in the LG screen is apparently thinner, lighter, and more flexible than conventional LCD displays.

According to LG, the screen “comes at a crucial time when smart devices are being used more than ever and at increased risk for damage from drops, hits, and other accidents.”

Yoon Bu-hyun, LG’s vice president of mobile, revealed last month that the company plans to launch a smartphone with a flexible OLED screen in the fourth quarter.

But other companies are also eyeing the technology. At the Computer Electronics Show in January, Samsung demoed a flexible display technology called Youm, which it said will allow its partners to create bendable, rollable, and foldable displays.

Let your shoes do the charging

Mechanical engineering student Julian Castro models his team’s PediPower prototype shoe to run small electronics.

Jeff Fitlow/Rice University)

After researching a device that draws energy from knee movement, some mechanical engineering students at Rice University decided to see if they could get the same result from another, less intrusive wearable item: a shoe.

With help from the Movement Analysis Laboratory at Shriners Hospital for Children in Houston, the resulting PediPower shoes harness energy from the force of the heel hitting the ground. The prototype — while admittedly big, unattractive, and impractical to wear 100 percent of the time (think sleeping, showering, etc.) — demonstrates that the simple act of walking may one day power a wide range of electronics, including medical devices such as pacemakers and artificial hearts.

“Theoretically, it would be something you just wear and you don’t notice it,” student Carlos Armada said in a school news release. “That’s the end goal. If you showed someone the shoe while you’re standing still, they wouldn’t even see the device.”

The PediPower, built into the heel of the prototype shoe, hits the ground first, at which point a lever arm strikes. This turns gears in a gearbox in the shoe’s sole, which then drives an electricity-generating motor mounted on the outside of the shoe.

The shoe, which delivers almost 400 milliwatts of power during walking tests, sends the energy through wires to a belt-mounted battery pack. A voltage regulator keeps the flow steady even in the mid-stride moments of rest.

“It may be worth looking into having both the heel and the ball of the foot produce power” if the design is ever modified for a high-tech running shoe, Armada said.

The students developed PediPower for Cameron, an international, Houston-based company that forged a partnership with the Texas Heart Institute to apply its flow-equipment expertise to next-gen artificial heart pumps.

Of course, relying on a shoe to power life-sustaining medical devices would require a sophisticated and reliable storage system when the shoes are not in use. The students are optimistic that another team at Rice will turn their proof of concept into bigger and better (read: smaller and smarter) power-generating shoes.

Cell phone charged in 20 seconds?


In this image from CNN affiliate KPIX, 18-year-old Eesha Khare shows off her device that can charge phones in seconds.

(CNN) — A tiny device that can recharge cell phone batteries in as little as 30 seconds won 18-year-old Eesha Khare a major science award that will help fund her college education at Harvard University.

Khare traveled from her California home to Phoenix last week for the Intel International Science and Engineering Fair, where her invention was honored as one of two winners of Young Scientist Awards.

“I’m in a daze. I can’t believe this happened,” Khare, a senior at Lynbrook High School in Saratoga, told CNN affiliate KPIX 5.

Khare’s device, a black, rectangular type of supercapacitor just over an inch long, can charge a cell phone battery in 20 to 30 seconds, she said.

“I developed a new supercapacitor, which is basically an energy storage device which can hold a lot of energy in a small amount of volume,” she told KPIX 5. The technology may also be able to speed up charging of automobile batteries, she said.

A videotape of the award ceremony showed an ecstatic Khare trotting up to the stage when her name was announced in Phoenix, then standing with other winners as the audience at the fair applauded and confetti fell on them.

The award includes a $50,000 prize that will come in handy when Khare heads to Harvard in the fall, she told KPIX 5. With a laugh, she predicted that “I will be setting the world on fire.”

In announcing the winners of what it billed as the “world’s largest high school research competition,” Intel cited Khare for recognizing “the crucial need for energy-efficient storage devices” as the world rapidly adopts portable electronics.

The other winner of a Young Scientist Award with Khare was Henry Lin of Shreveport, Louisiana, who received a $50,000 prize for “simulating thousands of clusters of galaxies” to allow scientists to “better understand the mysteries of astrophysics: dark matter, dark energy and the balance of heating and cooling in the universe’s most massive objects,” the Intel statement said.

The top prize at the fair went to 19-year-old Ionut Budisteanu of Romania, who used “artificial intelligence to create a viable model for a low-cost, self-driving car,” according to an Intel statement. He received the Gordon E. Moore Award, named after the Intel co-founder, which includes a $75,000 prize.

According to Intel, more than 1,500 young scientists from around the world were chosen to compete in last week’s fair.

Invasive crazy ants have a taste for technology

Tawny Crazy Ant

It sounds like an old black-and-white monster movie. Crazy, tech-nesting ants invade America! That would make for a great matinee, but it’s oh so very real. Tawny crazy ants, known scientifically as Nylanderia fulva, are marching into territories once dominated by fire ants — and they’re not being very good neighbors.

While fire ants have made their sting notorious, tawny crazy ants have a propensity to infiltrate unwelcome places en masse. They’re making fire ants look positively polite. The South American native ants are attracted to electronics in particular. Once inside, they create short circuits, says University of Texas research assistant Edward LeBrun.

“When they get electrocuted, they release an alarm pheromone,” he says, adding that this attracts more ants and exacerbates the problem.

LeBrun and two colleagues published a paper about the ant issue in the Biological Invasions journal, the most awesome science journal you’ve probably never heard of. So far, the invasive species has been found in Texas, Florida, Mississippi, and Louisiana.

“When you talk to folks who live in the invaded areas, they tell you they want their fire ants back,” LeBrun says.

Tawny crazy ants don’t sting, but the huge populations spill over into the walls of houses, potted plants, crawl spaces, vehicles, and electrical equipment. That’s about the last thing you would want to find when you open up your electrical box to check your breakers.

You might want to think twice about leaving your laptop outside in crazy ant territory, but the ants are more likely to get into fixed equipment, house wiring, and even recreational vehicles.

According to the Texas AM AgriLife Research Extension, some infestations have caused several thousands of dollars in damage and remedial costs.

Controlling the ant invasion is challenging. They crowd out native ants and they don’t respond to most poison baits. Texas AM recommends clearing clutter off the ground and hiring professional pest control services.

Teen’s science project could charge phones in 20 seconds

Intel science fair winners

My high school science project looked at how row covers could help plants grow in cold weather. Not a bad idea, but not nearly as cool as high school student Eesha Khare’s science project, the creation of a supercapacitor that could potentially be used to fully charge a cell phone within 20 to 30 seconds.

Khare, an 18-year-old from California, won the Intel Foundation Young Scientist Award and $50,000 for her participation in the Intel International Science and Engineering Fair run by the Society for Science the Public. Think of it as the world’s largest science fair. Khare took home one of the top prizes for “a tiny device that fits inside cell phone batteries, allowing them to fully charge within 20-30 seconds.”

The official title of Khare’s project is “Design and Synthesis of Hydrogenated TiO2-Polyaniline Nanorods for Flexible High-Performance Supercapacitors.” Her objective reads (PDF):

With the rapid growth of portable electronics, it has become necessary to develop efficient energy-storage
technology to match this development. While batteries are currently used for energy-storage, they suffer
from long charging times and short cycle life. Electrochemical supercapacitors have attracted attention as
energy-storage devices because they bridge the gap between current alternatives of conventional
capacitors and batteries, offering higher energy density than conventional capacitors and higher power
density than batteries. Despite these advantages, supercapacitor energy density is much lower than
batteries and increasing energy density remains a key challenge in supercapacitor research. The goal of
this work was to design and synthesize a supercapacitor with increased energy density while maintaining
power density and long cycle life.

Khare’s supercapacitor can last for 10,000 charge and recharge cycles. She has used it to power an LED as a proof of concept, but envisions its future use in phones, portable electronic devices, and even
car batteries.

Curious about how she did it? Put your science hat on. “To improve supercapacitor energy density, I designed, synthesized, and characterized a novel core-shell nanorod electrode with hydrogenated TiO2 (H-TiO2) core and polyaniline shell,” she writes. Essentially, that translates to a much improved supercapacitor.

The 1,600 participants were whittled down to 3 top winners. Besides Khare, Romanian student Ionut Budisteanu came in first by using artificial intelligence to create a model for a low-cost, self-driving car. Henry Lin, a 17-year-old from Louisiana, received the same award as Khare for his project that simulated thousands of clusters of galaxies.

Khare’s work is of particular interest to the geek world. The idea of a super-fast smartphone charge is enough to make most phone owners jump for joy. Let’s hope this tech gets on the fast track to commercialization.
