Touchscreen laptops appear to be rising in
popularity as the newest data from market research firm DisplayBank says
that touchscreen notebook shipments have jumped 51.8% during Q1 2013
compared to the previous quarter. A total of 4.57 million touchscreen
laptops were shipped during the quarter, making up 10% of all notebook
shipments during Q1 2013.
Throughout the entire Q1 2013 quarter, a total of 46 million laptops
were shipped, so 4.57 million touchscreen variants certainly isn’t a
lot, but with a healthy increase from the previous quarter, touchscreens
in laptops are becoming more popular than ever. Most likely, the number
of these kinds of laptops will only increase in the future.
Specifically, manufacturers like Lenovo, Acer and ASUS have set
higher targets for themselves to achieve over 20% of touchscreen market
share, which could be quite achievable, but it’s really only up to
consumers who want to adopt touchscreens in their laptops. We already
know Apple thinks that people don’t want them, but a 51.8% increase says otherwise.
Much of the adoption of touchscreen technology in laptops is thanks to Windows 8,
which includes a touchscreen-friendly start screen that you can swipe
and navigate around using your fingers. Of course, the new operating
system hasn’t received a lot of compliments lately, and its adoption
rate is slightly slower than what Microsoft or PC makers were expecting,
but most OEMs have added touchscreen laptops to their repertoire due in
part to Windows 8.
Plus, as laptop prices get lower and lower, touchscreen laptops will
become more affordable. Right now they’re quite on the pricey side, with
a decent machine running over $1,000, but former Intel CEO Paul
Otellini says that touchscreen laptops will break the $200 barrier in the near future, so the technology could eventually become the norm.
Millions of years of evolution has resulted in plants being the most
efficient harvesters of solar energy on the planet. Much research is
underway into ways to artificially mimic photosynthesis in devices like artificial leaves,
but researchers at the University of Georgia (UGA) are working on a
different approach that gives new meaning to the term “power plant.”
Their technology harvests energy generated through photosynthesis before
the plants can make use of it, allowing the energy to instead be used
to run low-powered electrical devices.
Photosynthesis turns light energy into chemical energy by splitting
water atoms into hydrogen and oxygen. This process produces electrons
that help create sugars that the plant uses to fuel growth and
reproduction. A team led by Ramaraja Ramasamy, assistant professor in
the UGA College of Engineering, is developing technology that would
interrupt the photosynthesis process and capture the electrons before
the plant puts them to use creating sugars.
The technology involves interrupting the pathways along which the
electrons flow by manipulating the proteins contained in thylakoids.
Thylakoids are membrane-bound compartments at the site of the light
reactions of photosynthesis that are responsible for capturing and
storing energy from sunlight.
The modified thylakoids are immobilized on a specially designed
backing of carbon nanotubes that acts as an electrical conductor to
capture the electrons and send them along a wire. The researchers say
that small-scale experiments of this system have yielded a maximum
current density that is two orders of magnitude larger than previously
reported for similar systems.
While you won’t be running your HDTV off the nearest tree anytime
soon, Ramasamy says the technology has the potential to find its way
into less power-intensive applications in the not too distant future.
"In the near term, this technology might best be used for remote
sensors or other portable electronic equipment that requires less power
to run," he said. "If we are able to leverage technologies like genetic
engineering to enhance stability of the plant photosynthetic
machineries, I'm very hopeful that this technology will be competitive
to traditional solar panels in the future."
Ramasamy and his team are already working to improve the stability
and output of the technology to get it to a stage suitable for
commercialization.
"We have discovered something very promising here, and it is
certainly worth exploring further," he said. "The electrical output we
see now is modest, but only about 30 years ago, hydrogen fuel cells were
in their infancy, and now they can power cars, buses and even
buildings."
But
Contractor, a mechanical engineer with a background in 3D
printing, envisions a much more mundane—and ultimately more
important—use for the technology. He sees a day when every kitchen has a
3D printer, and the earth’s 12 billion people feed themselves
customized, nutritionally-appropriate meals synthesized one layer at a
time, from cartridges of powder and oils they buy at the corner grocery
store. Contractor’s vision would mean the end of food waste, because the
powder his system will use is shelf-stable for up to 30 years, so that
each cartridge, whether it contains sugars, complex carbohydrates,
protein or some other basic building block, would be fully exhausted
before being returned to the store.
Ubiquitous food synthesizers
would also create new ways of producing the basic calories on which we
all rely. Since a powder is a powder, the inputs could be anything that
contain the right organic molecules. We already know that eating meat is
environmentally unsustainable, so why not get all our protein from insects?
If eating something spat out by the same kind of 3D printers that are currently being used to make everything from jet engine parts to fine art
doesn’t sound too appetizing, that’s only because you can currently
afford the good stuff, says Contractor. That might not be the case once
the world’s population reaches its peak size, probably sometime near the end of this century.
“I
think, and many economists think, that current food systems can’t
supply 12 billion people sufficiently,” says Contractor. “So we
eventually have to change our perception of what we see as food.”
There will be pizza on Mars

If
Contractor’s utopian-dystopian vision of the future of food ever comes
to pass, it will be an argument for why space research isn’t a complete
waste of money. His initial grant from NASA, under its Small Business
Innovation Research program, is for a system that can print food for
astronauts on very long space missions. For example, all the way to
Mars.
“Long distance space travel requires 15-plus years of shelf
life,” says Contractor. “The way we are working on it is, all the carbs,
proteins and macro and micro nutrients are in powder form. We take
moisture out, and in that form it will last maybe 30 years.”
Pizza
is an obvious candidate for 3D printing because it can be printed in
distinct layers, so it only requires the print head to extrude one
substance at a time. Contractor’s “pizza printer” is still at the
conceptual stage, and he will begin building it within two weeks. It
works by first “printing” a layer of dough, which is baked at the same
time it’s printed, by a heated plate at the bottom of the printer. Then
it lays down a tomato base, “which is also stored in a powdered form,
and then mixed with water and oil,” says Contractor.
Finally, the
pizza is topped with the delicious-sounding “protein layer,” which could
come from any source, including animals, milk or plants.
The prototype for Contractor’s pizza printer (captured in a video,
above) which helped him earn a grant from NASA, was a simple chocolate
printer. It’s not much to look at, nor is it the first of its kind, but at least it’s a proof of concept.
Replacing cookbooks with open-source recipes
SMRC’s prototype 3D food printer will be based on open-source hardware from the RepRap project.RepRap
Remember
grandma’s treasure box of recipes written in pencil on yellowing note
cards? In the future, we’ll all be able to trade recipes directly, as
software. Each recipe will be a set of instructions that tells the
printer which cartridge of powder to mix with which liquids, and at what
rate and how it should be sprayed, one layer at time.
This will
be possible because Contractor plans to keep the software portion of his
3D printer entirely open-source, so that anyone can look at its code,
take it apart, understand it, and tweak recipes to fit. It would of
course be possible for people to trade recipes even if this printer were
proprietary—imagine something like an app store, but for recipes—but
Contractor believes that by keeping his software open source, it will be
even more likely that people will find creative uses for his
hardware. His prototype 3D food printer also happens to be based on a
piece of open-source hardware, the second-generation RepRap 3D printer.
“One
of the major advantage of a 3D printer is that it provides personalized
nutrition,” says Contractor. “If you’re male, female, someone is
sick—they all have different dietary needs. If you can program your
needs into a 3D printer, it can print exactly the nutrients that person
requires.”

Contractor
is agnostic about the source of the food-based powders his system uses.
One vision of how 3D printing could make it possible to turn just about
any food-like starting material into an edible meal was outlined by TNO
Research, the think tank of TNO, a Dutch holding company that owns a
number of technology firms.
In TNO’s vision of a future of 3D printed meals, “alternative ingredients” for food include:
algae
duckweed
grass
lupine seeds
beet leafs
insects
From astronauts to emerging markets
While
Contractor and his team are initially focusing on applications for
long-distance space travel, his eventual goal is to turn his system for
3D printing food into a design that can be licensed to someone who wants
to turn it into a business. His company has been “quite successful in
doing that in the past,” and has created both a gadget that uses microwaves to evaluate the structural integrity of aircraft panels and a kind of metal screw that coats itself with protective sealant once it’s drilled into a sheet of metal.
Since
Contractor’s 3D food printer doesn’t even exist in prototype form, it’s
too early to address questions of cost or the healthiness (or not) of
the food it produces. But let’s hope the algae and cricket pizza turns
out to be tastier than it sounds.
Wikipedia is constantly growing, and it is written by people around the world. To illustrate this, we created a map of recent changes on Wikipedia, which displays the approximate location of unregistered users and the article that they edit.
Unregistered Wikipedia users
When an unregistered user makes a contribution to Wikipedia,
he or she is identified by his or her IP address. These IP addresses
are translated to the contributor’s approximate geographic location. A study by Fabian Kaelin in 2011 noted that unregistered users make approximately 20% of the edits on English Wikipedia [edit: likely closer to 15%, according to more recent statistics], so Wikipedia’s stream of recent changes includes many other edits that are not shown on this map.
You may see some users add non-productive or disruptive content to Wikipedia. A survey in 2007 indicated
that unregistered users are less likely to make productive edits to the
encyclopedia. Do not fear: improper edits can be removed or corrected by other users, including you!
How it works
This map listens to live feeds of Wikipedia revisions, broadcast using wikimon. We built the map using a few nice libraries and services, including d3, DataMaps, and freegeoip.net. This project was inspired by WikipediaVision’s (almost) real-time edit visualization.
Researchers with the NASA Jet
Propulsion Laboratory have undertaken a large project that will allow
them to measure the carbon footprint of megacities – those with millions
of residents, such as Los Angeles and Paris. Such an endevour is
achieved using sensors mounted in high locations above the cities, such
as a peak in the San Gabriel Mountains and a high-up level on the Eiffel
Tower that is closed to tourist traffic.
The sensors are designed to detect a variety of greenhouse gases,
including methane and carbon dioxide, augmenting other stations that are
already located in various places globally that measure greenhouse
gases. These particular sensors are designed to achieve two purposes:
monitor the specific carbon footprint effects of large cities, and as a
by-product of that information to show whether such large cities are
meeting – or are even capable of meeting – their green initiative goals.
Such measuring efforts will be intensified this year. In Los Angeles,
for example, scientists working on the project will add a dozen gas
analyzers to various rooftop locations throughout the city, as well as
to a Prius, which will be driven throughout the city and a research
aircraft to be navigated to “methane hotspots.” The data gathered from
all these sensors, both present and slated for installation, is then
analyzed using software that looks at whether levels have increased,
decreased, or are stable, as well as determining where the gases
originated from.
One of the examples given is vehicle emissions, with scientists being
able to determine (using this data) the effects of switching to green
vehicles over more traditional ones and whether its results indicate
that it is something worth pursuing or whether it needs to be further
analyzed for potential effectiveness. Reported the Associated Press,
three years ago California saw 58-percent of its carbon dioxide come
from gasoline-powered cars.
California is looking to reducing its emissions levels to a
sub-35-percent level over 1990 by the year 2030, a rather ambitious
goal. In 2010, it was responsible for producing 408 million tons of
carbon dioxide, which outranks just about every country on the planet,
putting it about on par with all of Spain. Thus far into the project,
both the United States and France have individually spent approximately
$3 million the project.
Scientists at the University of Manchester used wafers of graphene, the
discovery of which won researchers a Nobel Prize, with thin layers of other
materials to produce solar powered surfaces.
The resulting surfaces, which were paper thin and flexible, were able to
absorb sunlight to produce electricity at a level that would rival existing
solar panels.
These could be used to create a kind of “coat” on the outside of buildings to
generate power needed to run appliances inside while also carrying other
functions too, such as being able to change colour.
The researchers are now hoping to develop the technology further by producing
a paint that can be put onto the outside of buildings.
But the scientists also say the new material could also allow a new generation
of super-thin hand-held devices like mobile phones that can be powered by
sunlight.
Professor Kostya Novoselov, one of the Nobel Laureates who discovered
graphene, a type of carbon that forms sheets just one atom thick, said: “We
have been trying to go beyond graphene by combining it with other one atom
thick materials.
“What we have been doing is putting different layers of these materials one on
top of the other and what you get is a new type of material with a unique
set of properties.
“It is like a book – one page contains some information but together the book
is so much more.
“We have demonstrated that we can produce a very efficient photovoltaic
device. The fact it is flexible will hopefully make it easier to use.
“We are working on paints using this material as our next work but that is
further down the line.”
Professor Novoselov and colleagues at the University of Singapore found that
if they combined layers of graphene with single one atom thick layers of a
material known as transition metal dichalcogenides, which react to light,
they could generate electricity.
Their findings are published in the journal Science.
Professor Novoselov added: “We are taking about a new paradigm of material
science.
“We can make sandwiches of materials and produce any kind of functionality so
we can put transistors and photovoltaics to produce power for them.
“The implementations would go much further than simple solar powered cells.”
How serious
is the threat of killer robots? Well, it depends on whom you ask. Some people will tell you that the
threat is very real, and I don’t mean the guy with the tinfoil hat standing on
the street corner. A new draft of a report coming out of the U.N. Human Rights Commission
looks to negate the possible threat of the use of unmanned vehicles with the
ability to end human life without the intervention of another human being. As
you can guess the UN is anti-killer robots.
In the 22-page report,
which was released online as a PDF, the Human Rights Commission explained the
mission of the document in the following terms:
“Lethal
autonomous robotics (LARs) are weapon systems that, once activated, can select
and engage targets without further human intervention. They raise far-reaching concerns
about the protection of life during war and peace. This includes the question
of the extent to which they can be programmed to comply with the requirements
of international humanitarian law and
the standards protecting life under international human rights law. Beyond
this, their deployment may be unacceptable because no adequate system of legal accountability
can be devised, and because robots should not have the power of life and death
over human beings. The Special Rapporteur recommends that States establish national moratoria on aspects of LARs,
and calls for the establishment of a high level panel on LARs to articulate a
policy for the international community on the issue.”
So it looks
like you may just have to watch the sky’s after all.
The nearly 300-page Tallinn Manual,
which was created by an independent group of twenty international law
experts at the request of the NATO Cooperative Cyber Defense Center of
Excellence, works through a number of different cyber war scenarios,
being careful to base its legal logic on international conventions of
war that already exist. As a result, there's a clear distinction between
civilians and military combatants and a lot of clever thinking about
everything -- from what constitutes a "Cyber Attack" (Rule #30) to what
comprises a "Cyber Booby Trap" (Rule #44).
First, you’d have to determine if the cyber attack violated a state’s
sovereignty. Most cyber attacks directed against the critical
infrastructure or the command-and-control systems of another state would
meet that standard. Then, you’d have to determine whether the cyber
attack was of sufficient scope and intensity so as to constitute a “use
of force” against that sovereign state. Shutting down the power grid for
a few hours just for the lulz probably
would not be a “use of force,” but if that attack happened to cause
death, destruction, and mayhem, then it would presumably meet that
threshold and would escalate the legal situation to one of "armed
conflict." In such cases, warns the Tallinn Manual, sovereign states
should first attempt diplomacy and all other measures before engaging in
a retaliatory cyber-strike of proportional scale and scope.
But here's where it gets tricky - once we're in an "armed conflict,"
hackers could be re-classified as military targets rather than civilian
targets, opening them up to military reprisals. They could then be
targeted by whatever "kinetic force" we have available.
For now, enemy hackers in places like China can breathe easy. Most of
what passes for a cyber attack today – “acts of cyber intelligence
gathering and cyber theft” or “cyber operations that involve brief or
periodic interruption of non-essential cyber services” would not fall
into the “armed attack” category. Even cyber attacks on, say, a power
grid, would have to have catastrophic consequences before it justifies a
military lethal response. As Nick Kolakowski of Slashdot points out:
"In theory, that means a nation under cyber-attack that reaches a
certain level—the “people are dying and infrastructure is destroyed”
level—can retaliate with very real-world weapons, although the emphasis
is still on using cyber-countermeasures to block the incoming attack."
That actually opens up a big legal loophole, and that's what makes
the Tallinn Manual potentially so dangerous. Even the lead author of the
Tallinn Manual (Michael Schmitt, chairman of the international law
department at the U.S. Naval War College) admits that there's actually
very little in the manual that specifically references the word "hacker"
(and a quick check of the manual's glossary didn't turn up a single
entry for "hacker").
Theoretically, a Stuxnet-like hacker attack on a nuclear reactor that spun out of control and resulted in a Fukushima-type scenario could
immediately be classified as an act of war, putting the U.S. into
"armed conflict." Once we reach that point, anything is fair game. We're
already at the point where the U.S. Air Force is re-classifying some of its cyber tools as weapons and
preparing its own rules of engagement for dealing with the growing
cyber threat from China. It's unclear which, if any, of these
"cyber-weapons" would meet the Tallinn Manual's definitional requirement
of a cyber counter-attack.
The Tallinn Manual’s recommendations (i.e. the 95 rules) are not
binding, but they will likely be considered by the Obama Administration
as it orchestrates its responses against escalating hacker threats from
China. Rational voices would seem to tell us that the "kinetic force"
scenario could never occur, that a state like China would never let
things escalate beyond a certain point, and that the U.S. would never
begin targeting hackers around the world. Yet, the odds of a catastrophic cyber attack are no longer microscopically small.
As a result, will the day ever come when sovereign states take out
enemy hackers the same way the U.S. takes out foreign terrorists abroad,
and then hide behind the rules of international law embodied within the
Tallinn Manual?
We’ve already heard plenty about the Oculus Rift virtual reality headset,
and while we youngsters are pretty amazed by the technology, nobody has
their mind blown more than the elderly, who could only dream about such
technology back in their younger days. Recently, a 90-year-old
grandmother ended up trying out the Oculus Rift for herself, and she was
quite amazed.
Imagimind Studio developer Paul Rivot ended up grabbing an Oculus
Rift in order to play around with it and develop some games, but he took
a break from that and decided to give his grandmother a little treat,
by strapping the Oculus Rift to her head in order to experience a bit of
virtual reality herself.
The video is quite entertaining to watch, and
we can’t imagine what’s going on inside of her head, knowing that she
never grew up with such technology as the Oculus Rift, let alone 3D
video games. She even gets to the point where she thought the images
being displayed were actual images taken on-location, when in fact it’s
all 3D-rendered on a computer.
Currently, the Oculus Rift is out in the wild for developers only at
this point, and there’s no announced release date for the device,
although the company has noted that it should arrive to the general
public before the 2014 holiday season. In the meantime, it’s videos like
this that only excite us even more.
Remembering the passwords for all your sites can get frustrating.
There are only so many punctuation, number substitutes and uppercase
variations you can recall, and writing them down for all to find is
hardly an option.
Thanks to researchers at the UC Berkeley School of Information, you
may not need to type those pesky passwords in the future. Instead,
you'll only need to think them.
By measuring brainwaves with biosensor technology, researchers are
able to replace passwords with "passthoughts" for computer
authentication. A $100 headset wirelessly connects to a computer via
Bluetooth, and the device's sensor rests against the user’s forehead,
providing a electroencephalogram (EEG) signal from the brain.
Other biometric authentication systems use fingerprint or retina
scans for security, but they're often expensive and require extensive
equipment. The NeuroSky Mindset looks just like any other Bluetooth set and is more user-friendly, researchers say.
Brainwaves are also unique to each individual, so even if someone knew
your passthought, their emitted EEG signals would be different.
In a series of tests, participants completed
seven different mental tasks with the device, including imagining their
finger moving up and down and choosing a personalized secret. Simple
actions like focusing on breathing or on a thought for ten seconds
resulted in successful authentication.
The key to passthoughts, researchers found, is finding a mental task
that users won’t mind repeating on a daily basis. Most participants
found it difficult to imagine performing an action from their favorite
sport because it was unnatural to imagine movement without using their
muscles. More preferable passthoughts were those where subjects had to
count objects of a specific color or imagine singing a song.
The idea of mind-reading is pretty convenient, but if the devices
aren't accessible people will refuse to use it no matter how accurate
the system, researchers explain.
