Coffee may protect the liver

Three cups of coffee a day can reduce the risk of abnormal liver enzyme levels by 25 percent, regardless of how much caffeine it contains.

If you're looking for ways to extend your lifespan, then coffee might be a good choice. Researchers at the National Cancer Institute report that it may significantly benefit liver health. Their study, published this month in Hepatology, shows that higher coffee consumption – regardless of how much caffeine it contains – results in lower levels of abnormal liver enzymes. This suggests that chemical compounds in coffee other than caffeine may help to protect the liver.

Coffee consumption is highly prevalent, with more than half of all Americans over 18 drinking on average three cups per day, according to a 2010 report from the National Coffee Association. Moreover, consumption has increased by between 1-2% each year since the 1980s. Previous studies have found that coffee may lower the risk of developing diabetes, cardiovascular disease, non-alcoholic fatty liver disease, cirrhosis and liver cancer.

"Prior research found that drinking coffee may have a possible protective effect on the liver," said lead author Dr. Qian Xiao. "However, the evidence is not clear if that benefit may extend to decaffeinated coffee."

For this study, researchers examined the coffee-drinking habits of 28,000 people, using data from a national health survey conducted from 1999-2010. 14,000 of the subjects drank coffee. Several markers were compared to determine liver function, including blood levels of four enzymes. After adjusting for age, sex, race, education, smoking, alcohol consumption and other factors, the researchers found that compared with people who drank no coffee, those who drank three cups a day were about 25 percent less likely to have abnormal liver enzyme levels. Among the 2,000 or so who drank only decaffeinated coffee, the results were similar.

Dr. Xiao concludes: "Our findings link total and decaffeinated coffee intake to lower liver enzyme levels. These data suggest that ingredients in coffee, other than caffeine, may promote liver health. Further studies are needed to identify these components."

In a related development, researchers last month sequenced the coffee genome.

Wi-Fi up to five times faster coming in 2015

Samsung Electronics has developed a new way of transmitting Wi-Fi data five times faster than was previously possible. The new technology is expected to be available in consumer devices as early as 2015.

If you've been to a cafe or other public place recently and been frustrated at the slow speed of Wi-Fi, a new breakthrough by Samsung Electronics may soon change that. Researchers at the company have this week achieved the development of 60GHz Wi-Fi allowing transfer rates of 4.6Gbps, or 575MB per second. That is 5.3 times faster than the previous maximum speed for consumer devices (866Mbps, or 108MB per second).

Today's generation of Wi-Fi uses the 2.4Ghz and 5Ghz areas of the radio spectrum. The 60GHz band is currently unlicensed and offers major potential, but previous attempts to exploit it have failed to send data over significant distances, due to path loss and weak penetration properties. Samsung has overcome these issues through a combination of millimetre-wave circuit design, a high performance modem and wide-coverage beam-forming antenna. This eliminates co-channel interference, regardless of the number of devices using the same network.

Commercialisation is expected in 2015, with Samsung planning integration into a wide variety of products – including audio visual, medical devices and telecommunications equipment. It will also help to spur the Internet of Things.

“Samsung prides itself at being of the forefront of technology innovation, and is delighted to have overcome the barriers to the commercialisation of 60GHz millimetre-wave band Wi-Fi technology,” said Paul Templeton, General Manager of Samsung Networks UK. “This breakthrough has opened the door to exciting possibilities for Samsung’s next-generation devices, and has also changed the face of the future development of Wi-Fi technology, promising innovations that were not previously within reach.”

To give an idea of the speed: a 1GB movie will take less than three seconds to transfer between devices, while uncompressed high-definition videos could easily be streamed from mobile devices to TVs in real-time without any delay.

In our digital world, are young people losing the ability to read emotions?

Children's social skills may be declining as they have less time for face-to-face interaction due to their increased use of digital media, according to a psychological study by the University of California, Los Angeles (UCLA).

UCLA scientists found that sixth-graders who went five days without even glancing at a smartphone, television or other digital screen did substantially better at reading human emotions than sixth-graders from the same school who continued to spend hours each day looking at their electronic devices.

“Many people are looking at the benefits of digital media in education, and not many are looking at the costs,” said Patricia Greenfield, a distinguished professor of psychology at UCLA College and senior author of the study. “Decreased sensitivity to emotional cues — losing the ability to understand the emotions of other people — is one of the costs. The displacement of in-person social interaction by screen interaction seems to be reducing social skills.”

Researchers studied two sets of sixth-graders from a Southern California public school: 51 who lived together for five days at the Pali Institute, a nature and science camp about 70 miles east of Los Angeles, and 54 others from the same school. The camp doesn’t allow students to use electronic devices — a policy that many students found to be challenging for the first couple of days. Most adapted quickly, however, according to camp counsellors.

At the beginning and end of the study, both groups were evaluated on their ability to recognise people’s emotions in photos and videos. The students were shown 48 pictures of faces that were happy, sad, angry or scared, and asked to identify their feelings. They also watched videos of actors interacting with one another and were instructed to describe the characters’ emotions. In one scene, students take a test and submit it to a teacher; one of the students is confident and excited, the other is anxious. In another scene, one student is saddened after being excluded from a conversation.

The children who had been at the nature camp improved significantly over the five days in their ability to read facial emotions and other non-verbal cues to emotion, compared with the students who continued to use their media devices.

Researchers tracked how many errors the students made when attempting to identify the emotions in the photos and videos. When analysing photos, for example, those at the camp made an average of 9.41 errors at the end of the study, down from 14.02 at the beginning. The students who didn’t attend the camp recorded a significantly smaller change. For the videos, the students who went to camp improved significantly, while the scores of the students who did not attend camp showed no change. The findings applied equally to both boys and girls.

“You can’t learn non-verbal emotional cues from a screen in the way you can learn it from face-to-face communication,” said Yalda Uhls, lead author and senior researcher with the UCLA’s Children’s Digital Media Center, Los Angeles. “If you’re not practicing face-to-face communication, you could be losing important social skills.”

Students participating in the study reported that they text, watch television and play video games for an average of four-and-a-half hours on a typical school day. Some surveys have found that the figure is even higher nationally. Greenfield considers the results significant, given that they occurred after only five days. The implications of the research are that people need more face-to-face interaction — and that even when people use digital media for social interaction, they’re spending less time developing social skills and learning to read non-verbal cues.

“We’ve shown a model of what more face-to-face interaction can do,” Greenfield said. “Social interaction is needed to develop skills in understanding the emotions of other people.”

Emoticons are a poor substitute for face-to-face communication, Uhls concluded: “We are social creatures. We need device-free time.”

The research will appear in the October print edition of Computers in Human Behavior and is already published online.

Robotic butlers to appear in hotels

From next week, guests at the Aloft hotel chain may feel like they are living in the future, as a new robotic butler offers its services.

 

robotic butler

 

Aloft Hotels has announced A.L.O. as the company’s first “Botlr” (robotic butler). This futuristic service will be introduced on 20th August, making Aloft the first major hotel brand to hire a robot for both front and back of house duties.

In this role, A.L.O. will be on call 24/7 as a robotic operative, assisting the human staff in delivering amenities to guest rooms. Professionally “dressed” in a custom shrink-wrapped, vinyl collared uniform and nametag, A.L.O. can modestly accept tweets as tips. It will not only free up time for employees, allowing them to create a more personalised experience for guests, but will also enhance the hotel’s image and technological features.

Brian McGuinness, Global Brand Leader: “As you can imagine, hiring for this particular position was a challenge as we were seeking a very specific set of automated skills, and one that could work – literally – around the clock. As soon as A.L.O. entered the room, we knew it was what we were looking for. A.L.O. has the work ethic of Wall-E, the humour of Rosie from The Jetsons and reminds me of my favourite childhood robot – R2-D2. We are excited to have it join our team.”

 

 

A.L.O. was developed by Silicon Valley-based Savioke – a new startup company with funding from Google Ventures – which the robotics community has been eagerly anticipating. It uses a combination of sonar wave technology, lasers and cameras to avoid people and obstacles. It can facilitate and prioritise multiple guest deliveries, communicate easily with guests and various hotel platforms, and efficiently navigate throughout the property – including the elevator, using WiFi.

Steve Cousins, CEO of Savioke: “We are thrilled to introduce our robot to the world today through our relationship with Aloft Hotels. In our early testing, all of us at Savioke have seen the look of delight on those guests who receive a room delivery from a robot. We have also seen the front desk get busy at times, and expect Botlr will be especially helpful at those times, freeing up human talent to interact with guests on a personal level.”

The first A.L.O. reports for duty next week at Aloft Cupertino, next to the Apple HQ. If successful, all 100 of the company's hotels may introduce them during 2015. In the future, Cousins predicts a huge market for service robots like A.L.O.: “There are all these places, hotels, elder care facilities, hospitals, that have a few hundred robots maybe – but no significant numbers – and we think that's just a huge opportunity.”

Five daily portions of fruit and vegetables may be enough to lower risk of early death

Eating five daily portions of fruit and vegetables is associated with a lower risk of death from any cause, particularly from cardiovascular disease – but beyond five portions appears to have no further effect, finds a new study.

 

fruit and vegetables

 

These results conflict with a recent study published in BMJ's Journal of Epidemiology and Community Health suggesting that seven or more daily portions of fruits and vegetables were linked to lowest risk of death.

There is growing evidence that increasing fruit and vegetable consumption is related to a lower risk of death from cardiovascular disease and cancer. However, the results are not entirely consistent. So a team of researchers based in China and the United States decided to examine the association between fruit and vegetable intake and risk of all-cause, cardiovascular, and cancer deaths.

They analysed the results of sixteen studies involving a total of 833,000 participants and 56,000 deaths. Differences in study design and quality were taken into account to minimise bias. Higher consumption of fruit and vegetables was significantly associated with a lower risk of death from all causes, particularly from cardiovascular diseases.

Average risk of death from all causes was reduced by 5% for each additional daily serving of fruit and vegetables, while risk of cardiovascular death was reduced by 4 percent for each additional daily serving of fruit and vegetables. But the researchers identified a threshold around five servings per day, after which the risk of death did not reduce further.

In contrast, a higher consumption of fruit and vegetables was not appreciably associated with risk of death from cancer. The researchers suggest that — as well as advice to eat adequate amounts of fruit and vegetables — the adverse effects of obesity, physical inactivity, smoking and high alcohol intake on cancer risk should be further emphasised.

Although a threshold of five servings was identified, the team reiterates the importance of regular fruit and vegetable intake, concluding that their study "provides further evidence that a higher consumption of fruits and vegetables is associated with a lower risk of mortality from all causes, particularly from cardiovascular diseases. The results support current recommendations to increase consumption of fruits and vegetables to promote health and longevity."

World's first climate-controlled city planned for Dubai

Dubai is already known for its luxury tourist experience, super-tall skyscrapers and extravagant megaprojects. Now developers have announced it will host the world's first temperature-controlled city – incorporating the largest mall, largest domed park, cultural theatres and wellness resorts. Known as the "Mall of the World", this gigantic $7bn project will encompass 50 million square feet of floorspace, taking 10 years to construct.

Intended as a year-round destination, its capacity will be large enough to accommodate 180 million visitors each year in 100 hotels and serviced apartment buildings. Glass-roofed streets, modelled on New York's Broadway and London's Oxford Street, will stretch for 7 km (4.6 miles). These will be air-conditioned in summer as temperatures soar above 40°C, but the mall and its glass dome will be open to the elements during cooler winter months. Cars will be redundant in this "integrated pedestrian city."

"The project will follow the green and environmentally friendly guidelines of the Smart Dubai model," explained Ahmad bin Byat, the chief executive of Dubai Holding. "It will be built using state-of-the-art technology to reduce energy consumption and carbon footprint, ensuring high levels of environmental sustainability and operational efficiency."

In response to concerns about another real estate bubble, he insisted there was demand for such a project: "The way things are growing I think we are barely coping with the demand ... tourism is growing in Dubai," he said in an interview with Reuters. "This is a long-term project and we are betting strongly on Dubai."

Speaking at the launch of the mall, Sheikh Mohammed said: "The growth in family and retail tourism underpins the need to enhance Dubai's tourism infrastructure as soon as possible. This project complements our plans to transform Dubai into a cultural, tourist and economic hub for the 2 billion people living in the region around us – and we are determined to achieve our vision."

Mall of the World is one of several hi-tech, futuristic cities that could set the standard for eco-city designs in the coming decades. Others include China's car-free "Great City" (planned to be finished by 2020) and the Masdar City arcology (due in 2025).

High-tech solar-powered benches coming to parks

Boston area parks will be piloting a 21st century bench upgrade through a partnership with MIT Media Lab spin-off firm, Changing Environments. “Soofa,” as the bench is termed, is a solar-powered outdoor charging station that also collects and shares location-based data like air quality and noise level.

 

soofa

 

The high-tech benches will be deployed in green spaces over the next week, including in Titus Sparrow Park in the South End, the Boston Common, and the Rose Kennedy Greenway. The Soofa debuted last week at the White House Maker Faire in Washington, D.C., where select innovators and entrepreneurs gathered to encourage robust development of new American ideas.

“Your cell phone doesn’t just make phone calls; why should our benches just be seats?” said Mayor Walsh. “We are fortunate to have talented entrepreneurs and makers in Boston thinking creatively about sustainability and the next generation of amenities for our residents.”

The Soofa will provide more seating space and will be able to charge two phones at a time, building on the functionality of the first solar-powered seat by Changing Environments, which was successfully piloted in Boston in 2013.

“We’re delighted to continue the Greenway's partnership with New Urban Mechanics and the MIT Media Lab,” said Jesse Brackenbury, Executive Director of the Rose Kennedy Greenway Conservancy. “The Soofa will allow visitors and their phones to enjoy the sun on the Greenway.”

The City of Boston is asking residents to recommend one additional City of Boston park to install the Soofa. Residents are encouraged to go online and recommend a location at bit.ly/bosbench  or tweet the location to @newurbanmechs.

In addition, the designers at Changing Environments are asking Bostonians to submit ideas for names of the Soofas in each park through Twitter to @mysoofa or via the website, soofa.co. The winners will be invited to visit designers at the MIT Media Lab and see where it all started.

“Soofa is the first step into Smart Urban Furniture. The possibilities to update the city for the mobile generation are endless and long overdue,” said Sandra Richter, Co-founder and CEO of the young startup. “So are more female-lead startups which is why we hope to be a roll-model for women all over the world to found cool companies like Nan Zhao, Jutta Friedrichs and I did.”

Soofas are also being piloted at Babson College and at the Massachusetts Institute of Technology.

Shatterproof screens to protect smartphones

Polymer scientists at the University of Akron in Ohio have developed a transparent electrode that could change the face of smartphones, literally, by making their displays shatterproof.

 

cracked smartphone screen

 

In a recently published paper, researchers show how a transparent layer of nanowire-based electrodes on a polymer surface could be extraordinarily tough and flexible, withstanding repeated scotch tape peeling and bending tests. This could revolutionise and replace conventional touchscreens, according to Yu Zhu, UA assistant professor of polymer science. Currently used coatings made of indium tin oxide (ITO) are more brittle, most likely to shatter, and increasingly costly to manufacture.

“These two pronounced factors drive the need to substitute ITO with a cost-effective and flexible conductive transparent film,” Zhu says, adding that the new film provides the same degree of transparency as ITO, yet offers greater conductivity. The novel film retains its shape and functionality after tests in which it has been bent 1,000 times. Due to its flexibility, the transparent electrode can be fabricated in economical, mass-quantity rolls.

“We expect this film to emerge on the market as a true ITO competitor,” Zhu says. “The annoying problem of cracked smartphone screens may be solved once and for all with this flexible touchscreen.”

The findings are published by the American Chemical Society’s journal ACS Nano in a study titled “A Tough and High-Performance Transparent Electrode from a Scalable and Transfer-Free Method.”

A breakthrough in real-time translated conversations

At the Code Conference in California, Microsoft has demonstrated Skype Translator – a new technology enabling cross-lingual conversations in real time. Resembling the "universal translator" from Star Trek, this feature will be available on Windows 8 by the end of 2014 as a limited beta. Microsoft has worked on machine translation for 15 years, and translating voice over Skype in real time had once been considered "a nearly impossible task." In the world of technology, however, miracles do happen. This video shows the software in action. According to CEO Satya Nadella, it does more than just automatic speech recognition, machine translation and voice synthesis: it can actually "learn" from different languages, through a brain-like neural net. When you consider that 300 million people are now connecting to Skype each month, making 2 billion minutes of conversation each day, the potential in terms of improved communication is staggering.

Floating, self-sustaining city offers solution to overcrowding and ecological impacts

AT Design Office has unveiled its proposal for a hi-tech, floating metropolis. With self-sufficient energy, food and recycling systems, it could solve problems of overcrowding and environmental degradation on land.

As the world becomes ever more crowded, polluted and depleted of resources, there are often suggestions that we must explore space and colonise other planets to ensure our survival. However, perhaps we should look closer to home. Oceans cover more than 70% of the Earth's surface and represent a new, potentially massive opportunity for civilisation.

AT Design Office – a firm of architects and urban/interior/landscape designers – was commissioned by Chinese construction firm CCCC to investigate the possibility of self-sustaining, floating cities. They have now unveiled a proposal that is capable of housing many thousands of residents in a futuristic, hexagonal arrangement of modules with areas both above and below water.

This 10 km² (4 mi²) settlement would feature vertical farms and fish hatcheries to produce its own food, a garbage and recycling centre to sustainably handle waste, along with zero-carbon and energy efficient systems driven by tidal power. World class facilities would bring new opportunities for education, recreation, employment and business. According to AT, this would create a "vibrant, diverse and sustainable social and economic platform."

All living spaces in this floating city would have 360° views of the surrounding ocean scenery. Residents would enjoy close proximity to local facilities and public services, with fast and convenient transport provided in the form of electric vehicles and submarines, eliminating air pollution and congestion. Inhabitants could visit neighbouring cities or the mainland via submarines, cruise ships and ferries.

Trees and parks are designed to weave in a continuous public green belt, above and below water. The upper areas can provide public space usable for sports and recreation in a fresh air environment. A chimney in the central hub creates natural ventilation and lighting for the underwater sections and a gravity regulation system is located at the bottom.

While it may sound like science fiction, China Transport Investment Company is taking the project seriously and may begin a small-scale trial in 2015. Technologies featured in this design are already being used to build a 31 mile bridge connecting Hong Kong, Macau and Zhuhai. As the world adapts to rising sea levels, these types of amphibious settlements could be a fairly common sight by 2100.

FDA approves the first prosthetic arm controlled by muscle electrical signals

After eight years of development, a new hi-tech bionic arm has become the first of its kind to gain regulatory approval for mass production.

 

the luke prosthetic arm

 

The DEKA Arm System is part of the $100m Revolutionising Prosthetics program launched by the Defense Advanced Research Projects Agency (DARPA). Upper-limb prosthetic technology had for many years lagged behind lower-limb technology and the program sought to address this issue. The DEKA was made possible through a combination of breakthroughs in both engineering and biology, resulting in a bionic arm that offers near-natural control. It is nicknamed "The Luke", after Star Wars' Luke Skywalker who received a robotic replacement for the hand he lost in a fight with Darth Vader.

Simultaneous control of multiple joints is enabled by miniature motors and a variety of input devices, including wireless signals generated by sensors on the user's feet. Constructed from lightweight but strong materials, the battery-powered arm system is of similar size and weight to a real limb and has six user-selectable grips.

During eight years of testing and development, 36 volunteers took part in studies to refine the arm's design. Their feedback helped engineers to create a mind-controlled device enabling amputees to perform a wide range of tasks – preparing food, using locks and keys, opening envelopes, brushing hair, using zippers and feeding themselves, all of which greatly enhances their independence and quality of life.

Similar devices are being developed around the world, but this is the first of its kind to gain approval from the U.S. Food and Drug Administration (FDA). Dr. Geoffrey Ling, Director of DARPA's Biological Technologies Office, comments in a press release: "DARPA is a place where we can bring dreams to life."

Transparent solar-powered windows made possible by quantum dot breakthrough

The superior light-emitting properties of quantum dots can be applied to solar energy, helping to more efficiently harvest sunlight.

 

solar powered windows quantum dot technology

 

A house window that doubles as a solar panel could be on the horizon, thanks to recent work by Los Alamos National Laboratory researchers in collaboration with scientists from the University of Milano-Bicocca (UNIMIB), Italy. Their project demonstrates that superior light-emitting properties of quantum dots can be applied in solar energy by helping more efficiently harvest sunlight.

Quantum dots are ultra-small nanocrystals of semiconductor matter that are synthesized with nearly atomic precision. Their emission colour can be tuned by simply varying their dimensions. Colour tunability is combined with high emission efficiencies approaching 100%. These properties have recently become the basis of a new technology – quantum dot displays – employed, for example, in the newest generation of the Kindle Fire e-reader.

A luminescent solar concentrator (LSC) is a photon management device, representing a slab of transparent material that contains highly efficient emitters such as dye molecules or quantum dots. Sunlight absorbed in the slab is re-radiated at longer wavelengths and guided towards the slab edge equipped with a solar cell.

Lead researcher Victor Klimov explained: “The LSC serves as a light-harvesting antenna – which concentrates solar radiation collected from a large area onto a much smaller solar cell – and this increases its power output.”

“LSCs are especially attractive because, in addition to gains in efficiency, they can enable new interesting concepts such as photovoltaic windows that can transform house facades into large-area energy generation units,” said his colleague, Sergio Brovelli.

To implement their concept, Los Alamos researchers created a series of cadmium selenide/cadmium sulfide (CdSe/CdS) quantum dots, which were then incorporated by the Italian team into large slabs of transparent polymer. The particles are tiny, only about 10 nanometres (nm) across. For comparison, human hairs are typically 50,000 nm wide.

Spectroscopic measurements indicated virtually no losses to re-absorption on distances of tens of centimetres. Tests using simulated solar radiation demonstrated high photon harvesting efficiencies of around 10% per absorbed photon – achievable in nearly transparent samples – perfectly suited for utilisation as photovoltaic windows.

These findings are published in Nature Photonics. According to a report earlier this year, the quantum dot and quantum dot display (QLED) markets are expected to see a 42-fold growth in the next five years, reaching $6.4 billion by 2019.

World's first marijuana vending machines are unveiled in Colorado

In a sign of the changing times, marijuana is now publicly available from vending machines in Colorado. American Green, part of Tranzbyte Corporation, has begun distributing "Zazzz Machines" containing the drug. These utilise radio-frequency identification tags (RFID) to track the products, along with biometrics to verify a customer's age. They even accept Bitcoin, a new digital currency. The first machine was unveiled on 12th April and is located at the Herbal Elements store in Avon, Colorado. A recent Gallup poll showed a clear majority of Americans (58%) in favour of marijuana being made fully legal, with growing numbers admitting to have tried it. Colorado expects to collect nearly $100 million in tax revenue from recreational marijuana use this year – about 40% more than originally forecast.

Researchers discover groundbreaking method to commercialise graphene for electronics

Graphene has the potential to usher in a new era of next generation electronic devices, including flexible displays and wearable technology.

 

graphene

 

Samsung Electronics have announced a breakthrough synthesis method to speed the commercialisation of graphene, a unique material ideally suited for electronic devices. Samsung Advanced Institute of Technology (SAIT), in partnership with Sungkyunkwan University, became the first in the world to develop this new method.

“This is one of the most significant breakthroughs in graphene research in history,” said the laboratory leaders at SAIT’s Lab. “We expect this discovery to accelerate the commercialisation of graphene, which could unlock the next era of consumer electronic technology.”

Graphene has 100 times greater electron mobility than silicon, the most widely used material in semiconductors today. It is more durable than steel and has high heat conductibility as well as flexibility, which makes it the perfect material for use in flexible displays, wearables and other next generation electronic devices.

 

graphene electronic newspaper



Through its partnership with Sungkyungkwan University’s School of Advanced Materials Science and Engineering, SAIT uncovered a new method of growing large area, single crystal wafer scale graphene. Engineers around the world have invested heavily in research for the commercialisation of graphene, but have faced many obstacles due to the challenges associated with it. In the past, researchers have found that multi-crystal synthesis – the process of synthesising small graphene particles to produce large-area graphene – deteriorated the electric and mechanical properties of the material, limiting its application range.

The new method developed by SAIT and Sungkyunkwan University synthesises large-area graphene into a single crystal on a semiconductor, maintaining its electric and mechanical properties. The new method repeatedly synthesises single crystal graphene on the current semiconductor wafer scale.

 



Over the past several decades, the growth of the semiconductor industry has been driven by the ability to grow the area of a silicon wafer, while steadily decreasing the process node. In order to commercialise graphene to displace the industry’s reliance on silicon, it is vital to develop a new method to grow a single crystal graphene into a large area.

The research results are published in Science Magazine and ScienceExpress, one of the world’s most prestigious science journals.

A battery that charges in seconds

Nanotechnology startup company, StoreDot, has unveiled a ground-breaking battery capable of charging your smartphone and other devices in under 30 seconds.

 

 

At Microsoft’s Think Next symposium in Tel Aviv, StoreDot demonstrated the prototype of its ultra-fast-charge battery for the first time. This company specialises in technology that is inspired by natural processes. They have produced "nanodots" derived from bio-organic material that, due to their size, have both increased electrode capacitance and electrolyte performance. These nanodots – described as "stable, robust spheres" – have a diameter of just 2.1 nanometres and are made of chemically synthesized peptide molecules, short chains of amino acids that form the building blocks of proteins.

StoreDot’s bio-organic devices, which include smartphone displays, provide much more efficient power consumption, and are eco-friendly. While other nanodot and quantum-dot technologies currently in use are heavy metal based, and therefore toxic, StoreDot's are biocompatible and superior to all previous discoveries in the field. Using their method, the company is hoping to synthesize new nanomaterials for use in a wide variety of applications. Nano-crystals in memory chips, for example, could triple the speed of traditional flash memory, while image sensors could be five times more sensitive.

Furthermore, the nanodots are relatively inexpensive, as they originate naturally, and utilise a basic biological mechanism of self-assembly. They can be made from a vast range of bio-organic raw materials that are readily available and environmentally friendly.

The battery seen in the video above remains in the prototype stage, with a rather bulky form factor. However, the CEO of Storedot, Doron Myersdorf, says he is confident that a smaller version can be developed and on the market by 2017.
