DARPA kickstarts research into robot Viagra

Researchers at DARPA are working on robots with hugely increased power efficiency, chasing human-style actuation that would prolong battery life and significantly extend robotic runtime. The M3 Actuation program has set an ambitious 2,000-percent increase in power-transmission and application in robots, improving performance not only in areas like search & rescue and drones, but advanced prosthetic limbs and other fields.

It’s not just making more efficient motors. According to DARPA, successful teams might look at a combination of “low-loss power modulation, variable recruitment of parallel transducer elements, high-bandwidth variable impedance matching, adaptive inertial and gravitational load cancellation, and high-efficiency power transmission between joints.”

There will be two different tracks of work ongoing simultaneously, one with a more practical focus and another that will look more at the science and engineering behind actuation. The eye-candy is likely to show up in Track 1, where teams will be required to actually outfit physical robotics systems with their creations:

“Track 1 asks performer teams to develop and demonstrate high-efficiency actuation technology that will allow robots similar to the DARPA Robotics Challenge (DRC) Government Furnished Equipment (GFE) platform to have twenty times longer endurance than the DRC GFE when running on untethered battery power (currently only 10-20 minutes). Using Government Furnished Information about the GFE, M3 Actuation performers will have to build a robot that incorporates the new actuation technology” DARPA

DARPA is now inviting proposals from teams that believe they can put together something along those lines. The Maximum Mobility and Manipulation robotics program will culminate in a live competition in December 2013, followed by a second live final in December 2014.

Higgs hunt may stop short of naming “God particle”

Scientists at the Large Hadron Collider are likely to announce the most convincing evidence of the Higgs boson particle to-date at the CERN event on Wednesday, but not name it as such over an abundance of caution. Although official word isn’t expected to come until tomorrow, insiders involved in the research tell Nature that “in practice you would have to be monstrously sceptical not to be convinced by what we have now” with the evidence signal likely to be confirmed at between 4.5 and 5 sigma.

That’s just shy of the 5 sigma scientists involved in hunting for the Higgs boson have set as their goal, a figure which would mean a 0.00006-percent chance of mis-identification. Both ATLAS and CMS experiments are coming in at roughly the same point, the physicist sources claim; “without a doubt, we have a discovery,” one member of the ATLAS team said, though asked to be kept anonymous.

Meanwhile, much is being read into the fact that four of the original theorists behind the Higgs mechanism back in the 1960s have confirmed they will be present at the announcement event on Wednesday. François Englert, Carl Hagen, Peter Higgs and Gerald Guralnik will all be in attendance, but CERN head of comms James Gillies, insists “things are still evolving here … until the spokespersons of the ATLAS and CMS collaborations stand up in front of the audience, it’s premature to speculate.”

That reticence is apparently because exactly what they’ll say is still being decided. “The final decisions on what to say on Wednesday are still being made” the CMS source says.

If the Higgs boson really is identified, efforts will swing into action to see how much it matches the so-called standard model predictions, and whether it’s possible that other, hitherto unknown particles are affecting its decay rates, among other things.

NPD: Tablets To Overtake Notebooks By 2016 As The Most Popular Mobile ‘PC’

mobile PC shipments NPD

Tablets, and specifically the iPad from Apple, have been one of the big drivers for growth in mobile in the last couple of years, but figures out today from NPD indicate that their popularity is going to get even bigger: the market for tablets, its researchers predict, is set to boom from 121 million shipped tablets today to 416 million devices by 2017, when they will overtake notebooks to become the most popular mobile PC device, driven by a drop in costs and a rise in features. Overall mobile PC shipments will reach 809 million units by 2017, from 347 million today.

But over that time, the rise of tablets will remain largely a story about developed/mature markets. Regions like North America and Western Europe, along with single countries like Japan, currently account for 66 percent of all tablet shipments (and most likely sales), and that proportion, NPD predicts, will remain in the 60 percent range for the next five years. That works out to 254 million units by 2017, versus 80 million today.

NPD seems to say that this is partly due to a lack of infrastructure and available services in developing markets, but also that it is something of a self-fulfilling prophecy: vendors continue to focus on the mature markets with their new products, so that’s where they get bought: ”New entrants are tending to launch their initial products in mature markets,” Richard Shim, senior analyst at NPD DisplaySearch, notes in a statement.

The rise of tablets is also a story about the decline of notebooks. The market for these will continue to expand, but at a rate lower than the 28 percent that tablets will see: NPD says that by 2017 there will be 393 million notebooks shipped compared to 208 million today.

One takeaway from this: although Apple with its iPad line of tablets has dominated the tablet world in market and mindshare up to now, the space is far from penetrated, and that means that companies like Microsoft, Google and others still have a lot to play for.

Another is that we may continue to see a pressure on price, but that won’t necessarily mean a shortcut on features. Amazon has, by some estimates, ushered in the “death of the spec” with its Kindle Fire tablet, which pares down expensive features like cameras in favor of delivering a sub-$200 device, but NPD notes that it will be the features on those tablets — instant-on capability, battery life, portability, as well as multi-core processors, hi-res displays — that will make them a “compelling alternative” to notebooks for the mobile consumer.

Part of the reason we will see a lot of features continue to be incorporated into tablets is because of the emphasis of content on the devices. App stores are increasingly catering to tablet users. And figures from NPD itself indicate how they are becoming a major platform for traditional TV consumption. This kind of usage screams for better screens, faster processors and just generally awesome hardware.

But by the way, this is not to say notebooks are dying. Far from it — they will still account for 49 percent of the mobile PC market, NPD says, shipping 393 million units in 2017 compared to 208 million in 2012. It adds that notebook makers are also taking heed and looking to put more tablet-like features into their products — for example, becoming thinner and incorporating touch functionality.


Tablets to overtake notebooks in 2016 researchers predict

Tablet shipments will eclipse those of notebooks in just four years time, according to new research, as Apple’s iPad leads a slate storm that will overshadow traditional mobile computing. While the mobile market as a whole is expected to more than double by 2017, NPD DisplaySearch claims, that growth will be disproportionately driven by tablet sales, shipments of which are tipped to more than triple.

The research team suggests that notebook shipments will grow from 208m units this year to an estimated 393m units in 2017. Meanwhile, tablet shipments will grow from 121m this year to 416m units in the same period, with particular interest from the so-called “mature markets” of North America, Japan and Western Europe which are already showing traditional computing saturation.

“While the lines between tablet and notebook PCs are blurring, we expect mature markets to be the primary regions for tablet PC adoption” NPD DisplaySearch analyst Richard Shim says. “New entrants are tending to launch their initial products in mature markets. Services and infrastructure needed to create compelling new usage models are often better established in mature markets.”

Overall, the mobile PC market will grow from 347m units this year to in excess of 809m units by 2017. Tablet shipments will overtake those of notebooks sometime in 2016, it’s predicted.

Expedition to discover Amelia Earhart’s plane wreckage begins

Almost exactly a month ago I mentioned that researchers had concluded with a high likelihood of accuracy that famed pilot Amelia Earhart and navigator Fred Noonan had crash landed on a reef and lived for a short time on a nearby island. It is believed that the duo lived for a short time on a Pacific island called Gardner Island before succumbing to dehydration and starvation. Artifacts found on the small island led the researchers to the conclusion, but the team wants to find the wreckage of Earhart’s plane.

The researchers have set off on a $2.2 million expedition to use a torpedo-like submersible to search the depths below the reef where Earhart is believed to have crashed. The investigators believe that the wreckage of the Earhart’s Lockheed Electra aircraft lays the bottom of one of the reef walls. A second submersible equipped with cameras will be used to take photos of anything discovered in the ocean depths.

A photograph taken in October of 1937 showed what could be a strut and wheel from a Lockheed Electra sticking out of the water above the reef. We should know in short order when the team arrives and sends the remote-controlled submersible under the ocean to search for the aircraft wreckage. If the wreckage of Earhart’s plane is discovered one of the oldest and most famous mysteries in aviation history will be solved after decades.

Researchers use 3D printer, sugar, to create a fake artery network for lab-grown tissue

Researchers use 3D printer, sugar, to create a fake artery network for lab-grown tissue

Printing a chocolate heart is easy enough, but how about an actual organ? There are folks working on it, but it turns out those veins of yours aren’t exactly a breeze to replicate. Researchers at the University of Pennsylvania and MIT may have found a semi-sweet solution — dissolving a sugar lattice in a batch of living Jell-O. The research team uses a RepRap 3D printer and a custom extruder head to print a filament network composed of sucrose, glucose and dextran which is later encased in a bio-gel containing living cells. Once the confectionery paths are dissolved, they leave a network of artery-like channels in their void. Tissue living in the gel can then receive oxygen and nutrients through the hollow pipes.

The research has been promising so far, and has increased the number of functional liver cells the team has been able to maintain in artificial tissues. These results suggest the technique could have future research possibilities in developing lab-grown organs. MIT Professor Sangeeta Bhatia, who helped conduct the effort, hopes to push the group’s work further. “More work will be needed to learn how to directly connect these types of vascular networks to natural blood vessels while at the same time investigating fundamental interactions between the liver cells and the patterned vasculature. It’s an exciting future ahead.” Scientists at other labs could also get their mitts on the sweet templates since they’re stable enough to endure shipping. Head past the break for a video of the innard infrastructure.

O2 says calling just fifth most-used task on smartphones, suggests we call them ‘best buds’ instead

Galaxy Note review top

Virtually anyone who’s been a frequent smartphone user for the past few years has already suspected it, but O2 UK has provided some possible evidence in a study: calling is one of the last things we do these days. Although the number hasn’t gone down, the 12.1 minutes of time study subjects spend talking every day is just fifth-highest on the list of what they do with their smartphones. Web browsing (24.8 minutes) and social networking (17.5 minutes) dictate the largest slices of time, but the combined effect of all those apps, media playback and messaging leave voice as just 9.5 percent of the 128 minutes of daily use. The British carrier suggests the shift is more a virtue of smartphones becoming all-singing, all-dancing companions in our lives than from some disdain for human contact: about half of those asked have replaced alarm clocks and watches with their phones, while 39 percent depend on their smartphone as their main camera. There’s even 28 percent that no longer feel the need for a laptop. O2’s insights aren’t all-encompassing and don’t necessarily reflect how everyone uses their devices — they do, however, explain why we’re turning to phones that aren’t all that comfortable as phones.

New spray-on batteries could revolutionize energy storage

Renewable energy has been one of the most researched topics ever since gas and oil prices have begun to rise and people have paid attention to their effects on the environment. Making your home run on renewable energy can be quite challenging and in some instances (very) expensive, but a research team at Rice University has just discovered a way to make it a lot easier to create energy and even store it.

Imagine being able to take a bottle of substance and spray it on a wall of your house. Then the sprayed substance converts the sun’s energy into renewable solar energy and even stores it for you. Rice Universities researchers have come up with the designs to this and possibly many other types of spray-on batteries.

VITAL feel-good glass replaces pain with happy pane

Windows that make you feel happier and healthier? Working in an office might just become a more pleasurable experience if the research geeks at the German Fraunhofer institute have their way, cooking up panes with a special coating that specifically allows through wavelengths known to have a positive impact on the body’s hormonal balance. The end result, it’s claimed, is a sheet that “makes you feel as if the window is permanently open” researcher Walther Glaubitt says.

Traditional treated glass uses anti-reflective coatings for aesthetic purposes, the researchers point out, preventing reflections and allowing through the maximum amount of light to avoid needing so much artificial illumination. However, the human eye is particularly sensitive to blue light, and so the Fraunhofer tech focuses on allowing that through.

“Our biorhythms are not affected by the wavelengths that brighten a room the most, but rather by blue light,” engineer Glaubitt says. The coating they’ve given is an inorganic later, 0.1 micrometers thick, that exhibits maximum transmission at wavelengths between 450 and 500 nanometers, where the effects of blue light are at their strongest.

Shortages in blue light can lead to SAD (seasonal effectiveness disorder), issues with sleeping due to excess melatonin production, depression and other problems. Traditional methods to combat this include blue-LED “energy lights” such as the Philips model we reviewed last year.

UNIGLASS and Centrosolar Glas are planning to bring the specially-treated glass to market as “VITAL feel-good glass” in triple-glazed units, which would usually make the room feel no darker but which would prevent more blue light from making it through. In fact, while regular triple-glazing allows through 66-percent of light at the 460 nanometer wavelength – the blue area – the VITAL glazing will allow through 79-percent.

Future versions, however, will extend the coating to the outer-sides of the glass sheets, further improving transmission. In fact, it’s expected that UNIGLASS can achieve 95-percent transmission eventually.

New fuel cell keeps on going even once the fuel’s dried up

New fuel cell keeps on going even once the fuel''s dried up

Vanadium oxide seems to be the go-to guy in power storage right now. A new solid-oxide fuel cell — developed at Harvard’s School of Engineering and Applied Sciences — that can also store energy like a battery, also uses the stuff. In the new cell, by adding a VOx layer it allows the SOFC to both generate and store power. Example applications would be situations where a lightweight power source is required, with the potential to provide reserve juice should the main fuel source run out. The team who developed the cell usually work with platinum-based SOFCs, but they can’t store a charge for much more than 15 seconds. By adding the VOx, this proof of concept extended that by 14 times, with the potential for more lifespan with further development. Especially handy if you’re always running out of sugar.
