Flying bicycle

A duo of British designers' passion for cycling and life-long dreams of flight has spawned one of the world's first flying bicycles -- a conventional bike that converts to an easy-to-operate aircraft that they say can soar to 4,000 feet and cover 75 miles-plus after liftoff.


Yannick Read, 42, and John Foden, 37, who met while living on the same road in Kingston upon Thames, England, quickly learned that aside from both being designers and avid cyclists, they always wanted to fly. The two decided to partner on what they saw as the next step in cycling: aviation.


"Growing up we wanted to be pilots," Read told ABCNews.com. "But training and maintenance and cost are real barriers. We wanted to create an aircraft that was as accessible, relatively speaking, as could be."


Read said he sent a long-shot email to Jim Edmondson with British paramotor manufacturer Parajet in March 2011, in which he outlined the duo's design and concept for their flying bike. To his surprise, he was quickly greeted with an enthusiastic response.


Read and Folden were encouraged to widen their concept and told they could have the Jim Edmondson's assistance and support.

A different kind of flying bicycle recently achieved liftoff in Prague. Read more here.


The duo began to pen out ideas and concepts for what eventually became the Paravelo, a combination of a para-wing and a conventional bike, which tows a trailer carrying a powerful fan. Once in an open clearing, the cyclist can unfurl the para-wing, start the fan with an electric-start motor and, within a matter of yards, be airborne.


Read and Foden began a Kickstarter campaign this week with a goal of reaching £50,000 (about $78,000) to launch what he they're calling "safe, practical and affordable personal flight."


"We built a series of prototypes, and the current one is fairly polished," he said. "The next version, with funding, would be to develop, to ruggedize it, make it more robust, the way we envision it being used -- as a bicycle Monday to Friday. You will be able to commute on the bike. Then, make use of the flying capability."


Read says the latest prototype, which he describes as the size of a flight suitcase, can fit in the trunk of a car. "It's a niche product. We're not going to see cities with these swarming through the skies," Read said. "It's an unusual and adventurous evolution for the bicycle."


But is the flying bicycle, which in the U.K. doesn't require a special license to operate and is unregulated, totally safe for the average user? Read says it is.


"It's safe because of low air speeds. You're flying about 25 miles per hour, that low speed makes it so safe," he said. "In terms of controlling, it's like controlling a little Vespa scooter."


Training for flight in the Paravelo, Read says, can be completed in as little as seven days and, he adds, the vehicle could be useful for a number of professions, including park rangers and border patrol, as well as being a great addition for the adventurous weekender.


The prototype even features a built-in tent for what read calls "flamping," or flying and camping.


As for his and Foden's crowd-funding campaign, Read sees it not just as a way to help his dream take flight, but as exploratory means to gauge reaction and interest.


"Were being up front and saying that it looks pretty, and it works," he said. "We want to show it's a robust, practical, usable machine, that won't work just the day you buy it, but for many, many years.

Waterproof Samsung Galaxy S4 Active makes some waves

Samsung's Galaxy S4 line gets another family member in the Samsung Galaxy S4 Active, a hardened, ruggedized spin off of the company's flagship model.


Waterproof to a meter below the surface and for up to 30 minutes, the Active carries on computing with Android 4.2 Jelly Bean, Samsung's TouchWiz interface, and a 1.9GHz quad-core processor, the same as its more delicate Galaxy S4 sibling.


Many of its other specs are also similar, but one that stands out is the camera, whose 8-megapixel module can take this bad boy under the waves with its brand-new aqua mode.

I love that Samsung has finally made waterproofing a feature rather than a fail-safe against damage. A lot of other rugged handsets that make the same waterproof claims stop short of turning the capability into a real benefit.

The handset's lower-caffeinated camera compared with the original GS4's may seem like a downgrade for some, but for the S4 Active's price of $199.99 on AT&T, its rugged features are a pretty fair compromise. We'll know a lot more when the phone launches on June 21 (see the teaser video above). Our team will also plan to get our hands on the Galaxy S4 Active on June 20 in London.


Since the Galaxy S4 Active arrives this summer, I have a feeling we're going to have a heck of a time testing out its aqua camera mode firsthand. Pool party, anyone?

Chemical Probe Confirms That Body Makes Its Own Rotten Egg Gas, H2S, to Benefit Health

A new study confirms directly what scientists previously knew only indirectly: The poisonous "rotten egg" gas hydrogen sulfide is generated by our body's growing cells.

Hydrogen sulfide, or H₂S, is normally toxic, but in small amounts it plays a role in cardiovascular health.

In the new study, chemists developed a chemical probe that reacts and lights up when live human cells generate hydrogen sulfide, says chemist Alexander R. Lippert, Southern Methodist University, Dallas. The discovery allows researchers to observe the process through a microscope.

The researchers captured on video the successful chemical probe at work, said Lippert, an assistant professor in the SMU Department of Chemistry.

"We made a molecular probe that, when it reacts with hydrogen sulfide, forms a fluorescent compound that can be visualized using fluorescence microscopy," Lippert said. "This is the first time that endogenously generated hydrogen sulfide has been directly visualized in a living system. This confirms a lot of hypotheses that scientists have, but no one had the tools to directly detect it in real time."

H₂S is one of several small gaseous molecules increasingly recognized as key signaling molecules in the body. For example, H₂S helps reduce high blood pressure. Scientists discovered in the past decade that cells in the human body generate small quantities of H₂S molecules, which in turn deliver information to proteins. The proteins act on the information to perform critical functions in the body.

Previously, scientists couldn't observe H₂S being generated in live cells. As a result, researchers faced challenges when studying hydrogen sulfide in living systems, Lippert said. The new discovery now provides a tool to view directly how and when hydrogen sulfide is generated, he said. Lippert and study co-author chemist Vivian S. Lin made the discovery.

Discovery provides research tool for scientists to observe H₂S in live cells

"Having the tools to do this in living systems is going to open up a lot of possibilities and experiments for scientists," Lippert said. "As a tool, this will allow researchers to ask questions that weren't possible before."

Lippert's real-time video features live human cells, taken from the lining of blood vessels and treated with the chemical probe and with a protein known to promote cell growth. Once the cells start generating H₂S, they behave like squiggly fluorescent green worms.

The researchers' scientific article, "Cell-trappable fluorescent probes for endogenous hydrogen sulfide signaling and imaging H₂O₂-dependent H₂S production," was published online in theProceedings of the National Academy of Sciences.

Lippert and Lin authored the research with Christopher J. Chang, principal investigator. Lin is a PhD candidate at the University of California at Berkeley. Chang is with the Howard Hughes Medical Institute, University of California at Berkeley. Lippert and Lin carried out the research in Chang's UC Berkeley laboratory.

Discovery can help scientists attack diseases such as cancer

H₂S -- along with nitric oxide, carbon monoxide and others in this emerging class of gaseous signaling molecules -- assists the body's large proteins.

Large proteins do much of the functional work in the body, such as digesting the food we eat and harnessing the energy in the oxygen we breathe. Their size, however, forces them to move slowly inside the cell. In contrast, H₂S and other small gaseous molecules diffuse quickly and easily across cellular membranes, enabling them to travel much faster and rapidly deliver information that mediates critical functions, such as blood pressure regulation, Lippert said.

For their experiments, Lippert and Lin placed living endothelial cells cultured from the internal lining of a blood vessel into a petri dish under a microscope.

Lippert and Lin then added a chemical solution containing an azide-functionalized organic molecule that they'd synthesized to act as a molecular probe. They gave the cells time to absorb the probe, then added a protein solution known to stimulate blood vessel formation. As the cells initiated blood vessel formation, H2S was generated. In reaction, the scientists observed a steady increase in the probe's fluorescence.

"Essentially we're observing the initial events that lead to the building of new blood vessels, a process that's active in babies as they develop, or in women during their menstruation cycles," Lippert said. "We see the cells get really bright as they start moving around and ruffling their membranes. That's the H₂S being formed. In the control group, which weren't stimulated with the growth protein, they don't get any brighter and they don't move around."

The discovery provides new insights that can help scientists attack diseases, such as cancer, by starving the nutrient supply to a tumor, Lippert said.

"When tumors grow they need a lot of blood support because they need the nutrients to support their rapid growth," he said. "If you can stop blood vessel formation you could starve the tumor and the tumor will die. So inhibiting H₂S formation might be a way to treat cancer using this method."

iPhone 6 release date and news

Apple made the screen bigger last time. Is an even bigger iPhone on the way?

When Apple unveiled the iPhone 5, the reaction was a bit muted: where previous phones were massive leaps forward, the iPhone 5 was a bit longer and a lot easier to scratch.
So what can we expect from the next iPhone, the iPhone 6 or 5S? Let's see what we can glean from the varying sources of the internet - some reliable, some not so much. But when might the iPhone 6 release date even be?
One thing is for sure, with the release of such super handsets as the Samsung Galaxy S4, Sony Xperia Z and HTC One, the next iPhone will have to seriously up its game

iPhone 6 and the iPhone 5S are two different phones

The rumour mill doesn't seem too sure whether the next iPhone is going to be the iPhone 5S or the iPhone 6. Given the iPhone's history - from the 3G onwards, there's always been a half-step S model before the next numbered iPhone - we'd bet on an iPhone 5S first and an iPhone 6 a while later.
However, in May 2013 Stuff reported it received a photo of the till system at a Vodafone UK store (which it has since removed along with the reference to Vodafone), with '4G iPhone 6' listed. Interesting.
It's been suggested that there could even be three size variants of the new iPhone - check out these mocked up images by artist Peter Zigich. He calls the handsets iPhone 6 Mini, iPhone 6 & iPhone 6 XL.
Could we see both an iPhone 5S and iPhone 6 this year? Some reports suggest a new 5S in the middle part of the year before a revamped iPhone 6 towards the end of the year or very early in 2014.

 

iPhone 6 release date

Many pundits predict a summer iPhone 6 release date. It's quite likely that Apple is moving to a two-phones-per-year upgrade cycle, but we'd bet on a springtime 5S model and a bigger, iPhone 6, update in the Autumn, probably September.
Digitimes reckons predicts a summertime reveal for Apple's next generation phones, which again fits with a WWDC unveiling. In May it became clear that US carrier Verizon introduced an iPhone 5 price cut of as much as $100 USD.
Reports in April also suggested that Foxconn has added as many as 10,000 assembly line workers per week to its Zhengzhou plant as it readies itself for the iPhone 6 release date.
But Jefferies analyst Peter Misek reckons we'll see an iPhone 5S first, with a June 2014 release for the iPhone 6. Citi's Glen Yeung also believes that we won't see an iPhone 6 or cheap iPhone until 2014.

 

iPhone 6 casing

Multiple rumours say Apple's working on plastic cases for its next iPhone, mixing plastic and metal in such a way that "the internal metal parts [are] able to be seen from outside through special design." Could these images from Apple.pro be a new iPhone 6 complete with plastic casing? The cynic inside us says no, but you never know...
It's unclear whether such cases would be for the iPhone 5S or iPhone 6, or if Apple is simply considering making cheaper iPhone 4s to sell when the iPhone 3GS reaches the end of its life.
Speaking in March 2013, a KGI analyst said it believed Apple would turn to manufacturer Pegatron to make up to 75 per cent of low cost iPhone products. Indeed, rumours in early June 2013 pointed at a $399 price point for the cheap iPhone 6.

Pretty, yes, but also horrifically scratch-prone. Will your next iPhone have a plastic back?

The iPhone 6 will finally do NFC

That's what iDownloadblog reckons, quoting Jefferies analyst Peter Misek: it'll have a better battery too, he says. Many Android phones now boast NFC.
PayPal's chief information security officer, Michael Barrett said this during a recent keynote speech: "There is going to be a fingerprint enabled phone on the market later this year," he said. "Not just one, multiple."

Could this be inside the iPhone 6?

The iPhone 6 will run iOS 7

iOS 7 has been announced at WWDC 2013. It's a radical overhaul of the OS, especially in terms of the design which has fundamentally changed and is far flatter and more Android-like. There are rounded icons, striking colours and a stark font. There are new features, of course, such as Control Center, AirDrop and iTunes Radio.
We're expecting a September or October release date for iOS 7 in line with previous releases.

 

iPhone 6 storage

We've already seen a 128GB iPad, so why not a 128GB iPhone 6? Yes, it'll cost a fortune, but high-spending early adopters love this stuff.

iPhone 6 home button

According to Business Insider, of the many iPhone 6 prototypes Apple has made, one has a giant Retina+ IGZO display and a "new form factor with no home button. Gesture control is also possibly included" - more on that shortly. Mind you, it was mooted that Apple would dump the home button in time for iPhone 5, but it never happened.

iPhone 6 screen

The Retina+ Sharp IGZO display, would have a 1080p Full HD resolution. It's also been widely reported that Apple could introduce two handset sizes as it seeks to compete with the plethora of Android devices now on the market.
Take this one with a pinch of salt, because China Times isn't always right: it reckons the codename iPhone Math, which may be a mistranslation of iPhone+, will have a 4.8-inch display. The same report suggests that Apple will release multiple handsets throughout the year over and above the iPhone 5S and 6, which seems a bit far-fetched to us.
Patents show that Apple has been thinking about magical morphing technology that can hide sensors and even cameras. Will it make it into the iPhone 6? Probably not.
Could the touch screen even be transparent? Emirates 24/7 sin't the first source we'd turn to for bone fide rumours about a new smartphone, but it claims that an ultra-sensitive transparent touchscreen will make it into iPhone 6. The site also believes the display will be made by Sharp, which wouldn't be so surprising. One thing's for sure - a potential wraparound screen is probably a pipedream.
Jefferies analyst Peter Misek also says he believes the new iPhone will have a bigger screen. Different sizes also seem rather likely to us - the word on the street after WWDC 2013 was that there would be 4.7 and 5.7-inch versions.

 

iPhone 6 processor

Not a huge surprise, this one: the current processor is a dual-core A6, and the next one will be a quad-core A7. The big sell here is more power with better efficiency, which should help battery life.
Expect to see it in the 2013 iPad first, and expect to see an improved A6 processor, the A6X, in the iPhone 5S.

iPhone 6 camera

Apple's bought camera sensors from Sony before, and this year we're going to see a new, 13-megapixel sensor that takes up less room without compromising image quality.
An Apple patent, uncovered by Apple Insider in May 2013, shows a system where an iPhone can remotely control other illuminating devices - extra flashes. It would work in a similar manner to that seen in professional photography studios. Interesting stuff.

iPhone 6 eye tracking

One thing seems certain - Apple can't ignore the massive movement towards eye-tracking tech from other vendors, especially Samsung. It seems a shoe-in that Apple will deliver some kind of motion tech within the next iPhone, probably from uMoove.

The new iPhone will have better 4G LTE

On its UK launch, just one UK network had 4G LTE: Everything Everywhere, which currently offers 4G on the 1800MHz band. In 2013, all the other big names will be coming on board, offering 4G in other frequency bands. International iPhones already work across different 4G bands to the UK, so you can expect the UK iPhone 6 (and possibly the iPhone 5S) to be more promiscuous than the iPhone 5.
By the time the iPhone 6 emerges, iOS devices should also have "nonclassified communication approval" status from the US FCC, which means they won't need to go through a lengthy approval process.

iPhone 6 Wi-Fi may be 802.11ac

Apple likes to lead Wi-Fi standards adoption - its Airport really helped make Wi-Fi mainstream - and there's a good chance we'll see ultra-fast 802.11ac Wi-Fi in Apple kit this year. It's faster than Lighting, and not very frightening.

iPhone 6 wireless charging

Wireless charging still isn't mainstream. Could Apple help give it a push? CP Tech reports that Apple has filed a patent for efficient wireless charging, but then again Apple has filed patents for pretty much anything imaginable.
The tasty bit of this particular patent is that Apple's tech wouldn't just charge one device, but multiple ones. Here are more details on the iPhone 6 wireless charging patent.
Meanwhile, a further Apple patent seems to imply that future iPhones will be able to adjust volume as you move them away from your ear.
And could the iPhone 6 really have 3D? It's unlikely, but the rumours keep on coming.
