#The HIV Self Tests the World Needs Are Here The HIV Self Testing kit from U k. startup Biosure can change the way people think about getting tested.

The test is packaged to make it easy for anyone to sample their own blood and execute a foolproof test for AIDS all in the comfort and privacy of their own home.

The device boasts being the only to be approved legally in the U k. and with a European Conformity (CE) mark.

who will have increased access to collection sites and an improved overall battery recycling experience,'says Joe Zenobio, executive director of Call2recycle Canada.'

'With more sites, a focus on education, and an opportunity to build our collection networks together,

which already automatically adapt to their user's gait, speed and the ground terrain, but still require intentional thought.

Ingvarsson said Ossur was on the way to creating prosthetics that are integrated more with their user."

Assaults on government websites are now being detected ever few seconds according to Japanese cyber defense experts.

#Wearable device provides continuous fetal monitoring The Pregsense monitor has woven sensors into an elastic harness to provide data around the clock on the status of the fetus and the mother's health in the later stages of pregnancy.

A bluetooth-enabled device attached to the monitor collects and transmits data such as the mother and baby's heart rates to a smartphone and stores it on a secure cloud-based database accessible only to expectant mothers and their physicians.

The device is the work of the Nuvo Group, led by Oren Oz. He says a smartphone app will eventually provide a visual representation of the data gathered by the wearable monitor."

"Now you can see both you and the baby, the heart and all the data. What you are going to get in the app eventually is visualization that can tell you where the hand is,

you're going to see if the baby is awake, you can hear your baby's heartbeat anytime you want and obviously everything about you as the mom, the activity,

everything about your pregnancy will be put into data, "he explained as he demonstrated the device for mother-to-be,

a strap allowing mothers to stream soothing music from a smartphone to gently stimulate the fetus.

The Pregsense strap is designed to collect data to help physicians detect symptoms that may lead to complications in pregnancy earlier."

"It's the first time that you have a huge amount of data of women and babies together about heart rate, kickings,

position for fetus etc and we will be able to analyze this data to predict about events of pregnancy,

"said Varda Shalev, a medical informatics expert and active care primary physician. She is an external consultant to the Tel aviv-based Nuvo Group.

The sensors use a patented algorithm to filter the signals it picks up into two heartbeat recordings.

The data collected is of high enough quality to be useful for clinicians and researchers.""The sophistication of the technology and the sophistication of the sensors that we had designed for that is really making

what used to be clinical data collection into passive continuous reliable home data collection, "said Professor Nathan Intrator,

The consumer version of the product, known as Ritmo Beats, is to be launched for users by the end of 2015

The clinical grade FDA-regulated device, to be teamed with a group of physicians to monitor the data

though, learning almost exclusively online in forums and emails, Lachappelle has managed to synthesize a series of robotic hands that could change industries

so it kind of works kind of like a muscle sensor in that it picks up small electric discharges and turns that into something you can actually read within software,

"he told Reuters Television. One of the most important aspects of the Anthromod design is the way in

which it's controlled by the software, which Lachappelle says is different from the types of control that exist in other robotic platforms.

as more advanced controls are created it's the software that's doing the heavy lifting,

using algorithms that make the arm easier to use.""A good example is had we actually an amputee use the wireless brainwave headset to control a hand,

and he was able to fluently control the robotic hand in right around about 10 minutes,

with some using a wireless brainwave headset, designed more for prosthetic use. Another of his tele-robotic controlled hands was created with dangerous environments in mind

One of the most impressive aspects of the arm is not the hardware itself or even the software that controls it-but the fact that it can be 3d printed for a fraction of the cost of modern prosthetics.

This allows him to make complex internal structures to the designs which would otherwise be impossible,

"he told Reuters."The full robotic arm is actually open source, and so people are now actually able to take this,

showing his handiwork-all part of his effort at making the invention open source -which means anyone can take his technology

because we this open source, we want someone that has a 3d printer, or very little printing experience, to be able to replicate this,

to be able to use this for new applications, to be able to adapt it into new situations,

former federal employees affected by data breach Hackers breached the computers of the U s. government agency that collects personnel information for federal workers in a massive cyber attack that compromised the data of about 4 million current and former employees,

ADVERTISING OPM detected new malicious activity affecting its information systems in April and the Department of Homeland Security said it concluded at the beginning of May that the agency's data had been compromised.

The breach affected OPM's IT systems and its data stored at the Department of the interior's data center,

which is shared a service center for federal agencies, a DHS official said on condition of anonymity.

whether other agencies'data had been affected. OPM had previously been the victim of another cyberattack, as have various federal government computer systems at the State department, the U s. Postal service and the White house."

"The FBI is working with our interagency partners to investigate this matter, "the bureau said in a statement."

because Americans may expect that federal computer networks are maintained with state of the art defenses.""""It's clear that a substantial improvement in our cyber databases

and defenses is perilously overdue,"Schiff added d

#Mood-changing wearable tech sets pulses racing The makers of'doppel'call it the next generation of wearable technology-one that can actually change the mood of the user.

They say the device taps in to the body's natural rhythm and gives the wearer control over how alert

instead of the current crop that often just monitor the body's activity.""Wearables currently are centered mostly around monitoring

"Bennett told Reuters. Doppel is synchronized to each individual via a smartphone app that measures their resting heart rate.

"You take your resting heart rate through your phone, and then that's the bio-data we need to set the levels that you need to either (get) calm

or to get going. It's not a lot of data, but we're using it very smartly,

and that's the approach we take, "said co-developer Jack Hooper. To control the level of doppel's pulse,

with their controlled tests showing the device can improve alertness when correctly set to the user's preference.

It uses preoperative CT (computerized tomography) scan data to create a 3d X-ray image of the patient,

This combines with the intraoperative data from Chimaera's sensing technology to guide the surgeon to the precise location of a procedure,

The real-time data generation is designed to be used in conjunction with optical wearable technology, such as Google glass. This means a surgeon can literally'see'exactly where they are within the body at any point during an operation.

Karger said it could pave the way for wireless pain management for patients using, for example, their mobile phone:"

smaller than the width of a human hair, let the scientists determine the path a mouse walks using a remote control to inject drugs

The device is mounted to the head of the mouse and is powered by a small battery, removing the need for it to be wired,

In one such experiment, mice were made to walk in circles after a drug that mimics morphine was injected into the region of the mouse's brain that controls motivation and addiction.

#Candle power to charge smartphones A power outage-it's an experience all are familiar with and everyone dreads.

the TV goes black, the computers shut down as their batteries drain. And worst of all-your smartphone dies.

This scenario was one of the inspirations for Andrew Burns of California startup Stower to develop the candle charger.

Its simplistic design is based on the principles of thermoelectrics, which have been around since the early 1800's. Light a candle, fill the device with water,

That diffusion outputs between 2-3 watts, about the same amount of power derived from a USB port-perfect for charging smartphones and tablets.

or a smartphone is infinitely greater than a vacuum cleaner and they only need tiny little bits of energy,

The company has developed also a similar device designed to charge phones over a campfire. Burns advises to keep devices off

Myriads of potential applications await within the realm of mobile devices. obile device sizes are continuing to shrink

#Scientists Create Single-Molecule Diode The idea of creating a single-molecule diode a circuit element that directs current flow was suggested first more than 40 years ago, in 1974, by researchers Arieh Aviram of IBM Thomas

and buttons and computers,"said María Luz Rodríguez-Méndez, a professor of inorganic chemistry at University of Valladolid in Spain."

A variety of screen-printed sensors"taste"electrochemical compounds in the beer to predict the brews'color index and alcoholic strength 76 percent and 86 percent of the time.

The screen-printed electrodes, made by the company Dropsens, have an array of sensors that send signals to software the"brain"that analyzes the response patterns.

The device is portable about the size of two cigarette packs, said Méndez. There are four electrodes,

The researchers taught the software to recognize the signal patterns for each of the four lager styles.

the computer can then compare new beer samples against the established, learned signal patterns. They tested each of the 25 beer samples seven times.

"The nonspecific electrodes are responsible for their wealth of data. The phenols and electrodes send electrochemical signals to the computer as they interact.

The researchers immerse the electrodes in beer and track the electrochemical signals as they turn up the voltage,

After analyzing the data with two pattern-recognition models, the electronic tongue was able to place the commercial beer sample into the correct lager category with 100 percent accuracy.

The next steps for Méndez and her team will be modifying the commercial screen-printed electrodes with nanoparticles to make the sensors respond more clearly,

Using mouse models and human airway tissue taken from both asthmatic and non-asthmatic people,

and drawing them to the vortex core. Like a tornado, what happens to the particles depends strongly on their size.

when a mixture of small microparticles (less than 1 micron) and water were introduced they rotated slowly about the vortex core.

However, larger microparticles (household flour) were drawn into the core and were seen to spin at high speeds

First Model Of Regeneration Discovered By Nonhuman Intelligence An artificial intelligence system has for the first time reverse-engineered the regeneration mechanism of planaria, small worms that can regrow body parts.

However, no such tools yet exist for mining the fast-growing mountain of published experimental data in regeneration

Lobo and Levin developed an algorithm that would use evolutionary computation to produce regulatory networks able to"evolve"to accurately predict the results of published laboratory experiments that the researchers entered into a database."

so that the head-tail patterning outcomes of simulated experiments would match the published data, "Lobo said.

The algorithm compared the resulting shape from the simulation with real published data in the database.

gradually the new networks could explain more experiments in the database comprising most of the known planarian experimental literature regarding head vs. tail regeneration.

First Regenerative Model Discovered by Artificial intelligence The researchers ultimately applied the algorithm to a combined experimental dataset of 16 key planarian regeneration experiments to determine

After 42 hours, the algorithm returned the discovered regulatory network, which correctly predicted all 16 experiments in the dataset.

and is the first regenerative model discovered by artificial intelligence, "said Levin. Lobo and Levin are trained both in computer science

and bring an unusual perspective to the field of developmental biology. Levin majored in computer science and biology at Tufts before earning his Ph d. in genetics.

Lobo earned a Ph d. in the field before joining the Levin lab. The paper represents a successful application of the growing field of"robot science

"While the artificial intelligence in this project did have to do a whole lot of computations, the outcome is a theory of

All this suggests to me that artificial intelligence can help with every aspect of science, not only data mining but also inference of meaning of the data."

What Your Clothes May Literally Say About You In the future Wearing a computer on your sleeve may be a lot cooler than a plastic watch with an Apple logo on it-researchers at the University of Pittsburgh have designed a responsive hybrid material fueled by an oscillatory chemical reactions.

They can even perform computations based on changes in the environment or movement, and respond to human vital signs.

and Steven P. Levitan, Ph d.,John A. Jurenko professor of electrical and computer engineering, integrated models for self-oscillating polymer gels and piezoelectric micro-electric-mechanical systems to devise a new

reactive material system capable of performing computations without external energy inputs, amplification or computer mediation. The studies combine Balazs'research in Belousov-Zhabotinsky (BZ) gels, a substance that oscillates in the absence of external stimuli,

"allowing the material to be used for computation. Levitan adds, however, the computations would not be general purpose,

but rather specific to pattern-matching and recognition, or other non-Boolean operations.""Imagine a group of organ pipes,

and respond accordingly, thereby performing the actual computing.""Developing so-called"materials that compute"addresses limitations inherent to the systems currently used by researchers to perform either chemical computing or oscillator-based computing.

Chemical computing systems are limited by both the lack of an internal power system and the rate of diffusion as the chemical waves spread throughout the system,

Further, oscillator-based computing has not been translated into a potentially wearable material. The hybrid BZ-PZ model,

#Eye disease Detected-Using A Smartphone Researchers at the Medical and Surgical Center for Retina have developed software that detects eye diseases such as diabetic macular edema using a smartphone.

The technology was designed for general physicians who support the health system in Mexico to detect certain abnormalities without an ophthalmologist

It's obviously better and cheaper to prevent blindness rather than try to cure it so an app on a cellphone that just needs to focus on the eye is better in all ways.

The software was developed in collaboration with biomedical engineers from the ITESM and uses the camera of the phone to detect any abnormality in the thickness of the retina."

"The idea is to detect and prevent diseases in general practice. We are not replacing the specialist,

#New GHOST Technology Leaps Out Of The Screen Nothing will make you feel like Tony Stark more than being able to change the shape of displays with your hands,

pulling objects and data out of the screen and playing with them in mid-air.

Instead, we live in a world of flat-screen displays, even though the real world is not flat,

Being able to manipulate a display and drag features into a 3-D world is the purpose of GHOST (Generic,

and manipulate physical objects through the interfaces of computers and mobile devices.""This will have all sorts of implications for the future,

from everyday interaction with mobile phones to learning with computers and design work,"says GHOST coordinator Professor Kasper Hornbaek of the University of Copenhagen."

"It not only about deforming the shape of the screen, but also the digital object you want to manipulate, maybe even in mid-air.

Through ultrasound levitation technology, for example, we can project the display out of the flat screen.

And thanks to deformable screens we can plunge our fingers into it.""This breakthrough in user interaction with technology allows us to handle objects,

and even data, in a completely new way. A surgeon, for instance, will be able to work on a virtual brain physically, with the full tactile experience,

before performing a real-life operation. Designers and artists using physical proxies such as clay can mold

and store them in the computer as they work. GHOST researchers are also working with deformable interfaces such as pads and sponges for musicians to flex to control timbre, speed and other parameters in electronic music.

which allows data in bar charts to be pulled out of the screen by fingertips. The information,

The researchers have also been working with orphees flexible mobile devices with lycra or alloy displays

These can change shape automatically to form screens to shield your fingers when you type in a pincode, for example,

or to move the display to the twists and turns of a game. And such devices can be enlarged in the hand to examine data closer

and shrunk again for storing away in a case or pocket. One of the GHOST partners

#New tiny silicon chip paves the way for light-speed computers The smallest ever'ultracompact polarisation beamsplitter'-a component used in silicon photonic chips-has been developed by engineers in the US,

the device points to a new generation of computers that can transmit information at the speed of light."

when it comes into your laptop. In that conversion, you're slowing things down. The vision is to do everything in light."

and we now communicate with each other via underwater optical fibres that transmit light particles-or photons-between almost every continent On earth.

these optical fibres still have to work with existing electronic computer chips, which means once information is delivered to your computer or router in photon form,

it has to be converted into the slower electron form in order to be processed, which slows everything down.

and computer processing speeds would skyrocket. That means less power required and longer battery life.""With all light, computing can eventually be millions of times faster,

"Menon said. Menon and his team figured out how to take current beamsplitters, which are about 100 by 100 microns in size,

"The first supercomputers using silicon photonics-already under development at companies such as Intel and IBM-will use hybrid processors that remain partly electronic,

"the press release explains.""Menon believes his beamsplitter could be used in those computers in about three years.

Data centres that require faster connections between computers also could implement the technology soon, he says."

#Solar cells that work on cloudy days just hit a record-breaking 22.1%efficiency There's been plenty of good news about solar power lately-not only are governments around the world using it more and more,

Iron tablets weren working, as they were hard to distribute and left locals with unpleasant side effects, writes Philippa Roxby for BBC Health.

the announcement comes just a few days after another group of researchers made a biodegradable computer chip out of wood."

such as A t-shirt that capable of charging your iphone. So wee pretty excited to see what the researchers do with the material next l

#Light-based computers will be even more awesome than we thought Researchers have come up with an efficient way of transporting data between computer chips using light rather than electricity.

Not only does this mean that computers will be able to transmit data much, much faster, it also means we could build machines that consume far less energy.

Wee already able to send data in the form of photons at incredible speeds through the optical fibres that make up our Internet,

but right now when this data hits our computers, it has to slow down so it can be converted into electrons

and it's responsible for making our computers so hot.""Up to 80 percent of the microprocessor power is consumed by sending data over the wires, one of the researchers,

Jelena Vuckovic from Stanford university in the US, said in a press release. But while engineers are getting very close to creating computer chips that can process light,

theye struggled to find an efficient way to transmit that light across the thousands of different connections,

and having to create a new silicon structure to replace every single wire inside just one computer could be next to impossible.

by developing an inverse design algorithm that tells them exactly how to build the silicon structures they need to perform a desired task.

Theye already used the algorithm to design a working optical circuit, and have made several copies in their lab. Reporting in Nature Photonics,

who worked on the algorithm.""The fact that we could build devices this robust on our equipment tells us that this technology will be easy to mass-produce at state-of-the-art facilities."

By designing very precise segments of silicon and pairing them together-according to the instructions of the algorithm-the team are able to create switches or conduits that control the flow of photons,

By creating an algorithm that automates the development of these complex Swiss cheese silicon structures, the team has essentially"set the stage for the next generation of even faster

and far more energy-efficient computers that use light rather than electricity for internal data transport, "as the press release explains.

The algorithm could also be used to find design solutions to many other communication problems-all a researcher needs to do is plug in their desired result,

and the algorithm will come up with a plan. We're pretty excited to see what they do with it next h

powerlines and computers-more efficient. here a big effort to understand friction and control it,

#A camera has successfully been powered using spare Wi-fi signals Researchers in the US have tweaked a regular Wi-fi router

Even better, their work didn interfere with the router's data transfer speeds. The breakthrough could help researchers overcome one of the main challenges

Researchers have known long that the electromagnetic waves broadcast by Wi-fi routers could be harnessed for energy as well as sending information,

A team from the University of Washington in the US has accomplished now this by simply changing the way a router broadcasts.

"In the past, scientists have never been able to harness enough Wi-fi signals to power anything of much use.

in order to see how much power they could get from a nearby router. They found that the resulting voltages produced by the Wi-fi signals were never high enough to cross the operating threshold of around 300 millivolts.

But they often came close. The problem, they realised, was that Wi-fi routers don continuously blast out electromagnetic waves,

they send them out on a single channel in bursts. But by programming a router to broadcast noise across a range of Wi-fi channels even

when it wasn't transmitting information, they were able to pump out enough signals that their antenna could then use to provide continuous power to electronic devices.

and camera sensors using Wi-fi signals from a distance of six and five metres respectively,

and didn interfere with data transfer speeds. The results are published over at arxiv. org. The question that needs to be answered now is how these routers interfere with other signals in the area. aving a router next door that is blasting out signals on three Wi-fi channels might not be everybody idea of neighbourly behaviour,

writes MIT Technology Review. t is worth pointing out, however, that if this kind of interference turns out to be a problem for current routers,

it is one that could be solved in future generations. The next step is further testing on these routers under a range of different conditions to make sure they really can help to provide us with regular power for our devices

while we browse the Internet. And if that the case, then it could seriously change the way we power up our homes.
