Self-powered Flexible Mic/Speaker is 0.1mm Thin

May 18th 2017

Man cupping his ear

Led by Nelson Sepúlveda, Associate Professor at the Michigan State University, a team of researchers who recently reported a breakthrough in ferroelectret nanogenerators (FENGs) was able to further characterize the behaviour of their thin-film FENG as a flexible acoustic transducer capable of operating both as a loudspeaker and a microphone.

Their paper "Nanogenerator-based dual-functional and self-powered thin patch loudspeaker or microphone for flexible electronics" published in Nature Communications examines the FENG's energy conversion mechanism under various sound pressure levels (SPL). Because the 0.1mm thin polypropylene ferroelectret (PPFE) includes compressible charged voids behaving as deformable dipoles in a metal-insulator-metal structure (with conductive silver layers for electrodes on the faces of the film), the alternating waves of sound pressure are faithfully transduced into alternating electrical signals. Here, rather than focus on energy generation, the study focused on reading out the analogue signal produced by the polymer-based FENG and the results are compelling.

Big data, industry 4.0 and the Internet of Things (IoT). Terms most of us associate with professional services companies, not with farming and agricultural businesses.

However, automation technologies form a critical part of modern livestock and farm management systems. Many farmers though, especially those operating small and medium sized farms, might be overlooking a critical aspect of power quality in their automated livestock farming systems.

The smart agriculture market is currently growing at a compound annual growth rate (CAGR) of 13.8 per cent and is expected to be worth $18.45 Billion by 2022, according to research firm MarketsandMarkets. The main factors driving growth include an increased adoption of technology in agriculture generally, a higher demand for food globally and assistance in monitoring livestock performance and health.

Separator Layer Can Make Lithium-ion Batteries Fireproof

April 15th 2017

batteries

Lithium-ion batteries, though being considered as the power source of choice for today’s electric vehicles, are having a significant disadvantage: They are not fireproof. Even worse, they tend to catch fire under overload and short circuit conditions which can occur as a consequence of accidents. Researchers from the Stanford University have developed a potential solution.

The reason why lithium ion batteries can start burning so easily is that the electrolytes necessary to enable the exchange of electrons between cathode and anode are flammable and highly reactive. Though battery manufacturers have tried to minimize this risk through internal protective covers or by adding flame retardants, the risk persists, acknowledged Stanford researcher Kai Liu. In addition, these measures have side effects: They reduce the energy density and ion mobility which in turns reduces the battery performances.

Smartphone Fingerprint Security Vulnerable

April 13th 2017

Smart phone

No two people are believed to have identical fingerprints, but researchers at the New York University Tandon School of Engineering and Michigan State University College of Engineering have found that partial similarities between prints are common enough that the fingerprint-based security systems used in mobile phones and other electronic devices can be more vulnerable than previously thought.

The vulnerability lies in the fact that fingerprint-based authentication systems feature small sensors that do not capture a user's full fingerprint. Instead, they scan and store partial fingerprints, and many phones allow users to enroll several different fingers in their authentication system.

Identity is confirmed when a user's fingerprint matches any one of the saved partial prints. The researchers hypothesized that there could be enough similarities among different people's partial prints that one could create a "MasterPrint."

Nasir Memon, a professor of computer science and engineering at NYU Tandon and the research team leader, explained that the MasterPrint concept bears some similarity to a hacker who attempts to crack a PIN-based system using a commonly adopted password such as 1234. "About four percent of the time, the password 1234 will be correct, which is a relatively high probability when you're just guessing."

Glove Biosensor Detects Nerve Agents

April 6th 2017

Worker contemplates nuclear waste

An international team of researchers from the University of California, San Diego and the Australia-based Commonwealth Scientific and Industrial Research Organisation (CSIRO) have devised a disposable 'lab-on-a-glove' enabling the wearer to identify health-threatening biochemical agents through a simple and secure swipe across a surface to be tested.

The researchers used tailor-made printable inks stencil-printed as serpentine patterns on regular purple nitrile powder-free exam gloves to create stretchable, yet robust conductive circuits. The thumb is used as a sample collection surface and only sports a printed stretchable carbon disk to ensure the adhesion of analyte residues.

At the tip of the index, part of an electrochemical cell is printed, immobilizing the enzyme organophosphorus hydrolase (OPH) capped with a conductive semi-solid gel matrix (covering an enzymatic OPH/Nafion layer) for analyte diffusion from the collection pad towards the OPH enzyme layer on the working electrode. The enzyme reacts to the presence of organophosphate (OP) compounds, also known as nerve agents for their high neurotoxicity.

Science Sting Exposes Corrupt Journal Publishers

March 23rd 2017

Physician and stethoscope

Spring break season is here, and, like a lot of beachgoers, science too is suffering some stings — albeit not of the jellyfish kind.

In the latest ploy, reported Wednesday, a group of researchers at the University of Wroclaw, in Poland, tried to seat a fictional scholar onto the editorial boards of 360 academic publications.

The goal: to test whether, with just a CV — full of fake scientific degrees — and a profile on Academia.edu as well as a fake university, some would accept a scholar named “Anna O. Szust” (which translates to “Anna, a Fraud” in English) as a member of their editorial boards.

And many did. The sting, reported in Nature, netted 48 journals — nearly all of which were so-called “predatory” journals. Such journals accept manuscripts without reviewing them, print them without editing them, and otherwise make a mockery of the scientific literature by pumping out low-quality work. Read more ..

Researchers from the Renmin University of China have devised a very cheap and scalable temperature sensor made out of paper and traces of gold (for the electrodes) joined by a line of inkjet printer-ready ionic ink as the thermistor.

Publishing their results in the ACS Sensors journal under the title "Ultrafast Paper Thermometers Based on a Green Sensing Ink", they detail a very simple implementation where they leverage the benefits of paper as a flexible substrate and the ionic liquid, 1-ethyl-3-methyl imidazolium bis(trifluoromethylsulfonyl)imide ([EMIm][Tf2N]) for its non-volatile and hydrophobic nature.

Transferred to regular A4 paper by pen writing or inkjet printing, the ionic liquid holds onto the paper through the capillary effect, showing no leakage during bending and folding. The electrical conductivity of the ink trace is measured between two sputtered gold electrodes (5mm wide and 1.5cm long in the experiment) connected to an external power supply.

The Quest to Crystallize Time

March 14th 2017

Taurus Molecular Cloud

Christopher Monroe spends his life poking at atoms with light. He arranges them into rings and chains and then massages them with lasers to explore their properties and make basic quantum computers. Last year, he decided to try something seemingly impossible: to create a time crystal.

The name sounds like a prop from Doctor Who, but it has roots in actual physics. Time crystals are hypothetical structures that pulse without requiring any energy—like a ticking clock that never needs winding. The pattern repeats in time in much the same way that the atoms of a crystal repeat in space. The idea was so challenging that when Nobel prizewinning physicist Frank Wilczek proposed the provocative concept in 2012, other researchers quickly proved there was no way to create time crystals.

But there was a loophole—and researchers in a separate branch of physics found a way to exploit the gap. Monroe, a physicist at the University of Maryland in College Park, and his team used chains of atoms they had constructed for other purposes to make a version of a time crystal. “I would say it sort of fell in our laps,” says Monroe.

How Plants Evolved into Carnivores

Any insect unlucky enough to land on the mouth-like leaves of an Australian pitcher plant will meet a grisly end. The plant's prey is drawn into a vessel-like ‘pitcher’ organ where a specialized cocktail of enzymes digests the victim.

Now, by studying the pitcher plant's genome—and comparing its insect-eating fluids to those of other carnivorous plants—researchers have found that meat-eating plants the world over have hit on the same deadly molecular recipe, even though they are separated by millions of years of evolution.

“We’re really looking at a classic case of convergent evolution,” says Victor Albert, a plant-genome scientist at the University of Buffalo, New York, who co-led the study. Read more ..

New Era of Exoplanet Discoveries In Store

January 24th 2017

New Earth Sized Planets

For astronomers seeking Earth twins around other stars, the exoplanet GJ 1132 b probably isn’t an identical sibling—but it may be the closest cousin yet found. It weighs in at just over one Earth mass, but circles its star in a warm orbit that could make it more like Venus than our own world. Moreover, its diameter is nearly 50 percent larger than that of Earth, suggesting it possesses a thick atmosphere. Now, after taking the closest-ever look at GJ 1132 b, a European collaboration has confirmed the presence of its atmosphere and found hints it might contain water and methane. The results are currently under review for publication in The Astrophysical Journal.

As mere discoveries of exoplanets become routine, efforts to learn more about them—their compositions, climates and histories—are moving to the fore, with studies of their atmospheres occupying center stage. Although astronomers detected the first exoplanet atmosphere more than 15 years ago, they have only managed to observe a handful ever since, mostly for very hot worlds as big as Jupiter or even larger. With their first glimpse of GJ 1132 b’s alien air, astronomers are now entering a new frontier as they examine the atmospheres of smaller, more Earth-like worlds.

The Pentagon’s research and development division, DARPA—the creative force behind the internet and GPS—retooled itself three years ago to create a new office dedicated to unraveling biology’s engineering secrets. The new Biological Technologies Office (BTO) has a mission to “harness the power of biological systems” and design new defense technology. Over the past year, with a budget of about $296 million, it has been exploring challenges including memory improvement, human–machine symbiosis and speeding up disease detection and response.

DARPA, or the Defense Advanced Research Projects Agency, is hoping for some big returns.

NASA Should Build a Superhighway in Space

January 5th 2017

Mars & Earth, Christopher Leather U Chicago

Donald Trump will take power any minute now, and we need to take advantage of the change in the White House to change NASA's focus.

Why? NASA needs to get out of the rocket business and shift its attention to a permanent space transport infrastructure, an Eisenhower-style highway in the sky. An infrastructure with:

  • Gas stations (propellant depots),
  • Rest stops and permanent housing—roomy human habitats with windows and vegetable gardens,
  • Truck stops and freight yards—logistics bases with cargo-handling equipment,
  • Trucks, SUVs, and dune buggies—Moon-and-Mars ground vehicles; plus tugs to haul loads around in space,
  • Fuel production equipment—units to turn the water of the Moon and Mars into rocket fuel, breathable oxygen, and drinkable water,
  • Units to turn the carbon dioxide in Mars' atmosphere into plastics, graphene, and carbon fiber with which 3-d printers can build more habitats, tools, and rovers—more trucks, SUVs and dune buggies.
  • Units to turn the rusty rocks lying around on the Martian surface into high strength steel for habitats. 

Why move NASA into space highway construction? Because no one else will do it. And our future in space depends on it. Our future share in a space economy that United Launch Alliance (a joint venture rocket company from Boeing and Lockheed Martin) estimates will be worth $2.7 trillion in thirty years.

Do you see dogs everywhere?

My ears perk up to the jingle jangle of metal-on-metal, hopeful that it predicts a dog and his collar, disappointed when it turns out to be keys on a belt (boring).

A person walking down the street with their arm outstretched holds the promise of a leash with a dog on the other end (sometimes it’s a stroller holding a kid. Oh well).

From a distance, my eyes play a cruel trick on me, where shopping bags are dogs and dogs are shopping bags until I get close enough and one wins out (obviously I'm rooting for the dog).

But catch any part of a tail, and I know I'm in. You could say my motto is, “dog, until proven otherwise.”

How about dogs?

Does a dog know, merely by sight, that an approaching being is a fellow dog? Before you answer, remember this: Canis familiaris is the least uniform species on the planet. Members of this species come in a wide range of body shapes and sizes from itty bitty teeny weeny to absolutely ginormos. Adult members of this species appear as tight little packages, huge weightlifters, lean ballerinas, elongated hotdogs and everything in between.

Hunting Dark Matter between the Ticks of an Atomic Clock

Dark matter is thought to make up some five sixths of all matter in the universe. Yet incredibly sophisticated projects ranging from the most powerful atom smasher ever built to vats of chilly liquid xenon have failed to find a trace of it. But now some scientists are hoping atomic clocks, the most precise timekeepers ever made, could be used to help explain this elusive phenomenon.

Many physicists believe dark matter is an invisible substance whose predicted gravitational effects on known matter would help explain a variety of cosmic mysteries, such as why galaxies can spin as fast as they do without flying apart. Despite its apparently colossal importance to the very structure of the universe, however, no one knows anything for certain about what it might be composed of or where it came from.

New Diagnosis for Parkinsons Advanes the Cause

Doctors diagnose as many as 60,000 new cases of Parkinson’s disease (PD) every year in the United States. Yet diagnosing PD with certainty can take years — long after early signs and symptoms have appeared.

The Israeli startup BioShai has a game-changing product on the horizon: PDx, the world’s first simple blood test for the early diagnosis of PD.

The test results can be combined with clinical data, providing a more accurate diagnosis to help physicians decide on the best course of treatment at a much earlier stage.

More than 10 million people worldwide are living with this chronic and progressive movement disorder caused by the malfunction and death of neurons that produce dopamine, a chemical that coordinates the brain’s control of movement and coordination.

“Having a diagnosis at an earlier stage can lead to a more precise treatment and a higher quality of life for the patient,” says BioShai CEO Jennifer Yarden, who has a PhD in medical science and formerly was responsible for clinical and commercial development of diagnostic assays and kits at Glycominds. Yarden is also CEO and cofounder of Curewize Health.

“Offering a simple and inexpensive test for the diagnosis of Parkinson’s is considered essential for the development of neuroprotective therapy,” she explains, “because by the time a patient has the many movement symptoms associated with Parkinson’s, a majority of the dopamine-producing neurons are lost or become impaired by the disease.”

Levels of highly toxic mercury contamination in Atlantic bluefin tuna are rapidly declining, according to a new study. That trend does not affect recommended limits on consumption of canned tuna, which comes mainly from other tuna species. Nor does it reflect trends in other ocean basins. But it does represent a major break in the long-standing, scary connection between tuna and mercury, a source of public concern since 1970, when a chemistry professor in New York City found excess levels of mercury in a can of tuna and spurred a nationwide recall. Tuna consumption continues to be the source of about 40 percent of the mercury contamination in the American diet. And mercury exposure from all sources remains an important issue, because it causes cognitive impairment in an estimated 300,000 to 600,000 babies born in this country each year.

Plants Can Now Be Used to Detect Explosives

Scientists at MIT have successfully bioengineered spinach to wilt if explosive material is detected in groundwater, according to a paper put out in the prestigious Journal of Nature Materials.

The research paper is titled “Nitroaromatic detection and infrared communication from wild-type plants using plant nanobionics.”

Here, we demonstrate that living spinach plants (Spinacia oleracea) can be engineered to serve as self-powered pre-concentrators and autosamplers of analytes in ambient groundwater and as infrared communication platforms that can send information to a smartphone,” the paper’s authors said their introduction.

As the plant absorbs water from the ground it will also absorb the explosive material. Thanks to deliberately created adaptations in the plant’s leaves, the plant will wilt in response to the presence of the explosive compounds.

Fixed sensors nearby will monitor the spinach using infrared technology and will pick up on the change in the plant.  

The project was funded by DARPA, the body of the U.S. military in charge of research and development. It has an annual budget of nearly $3 billion and funds a vast array of different technologies that either have or could potentially have military application. Read more ..

With this year’s approaching holiday gift season the rapidly growing “Internet of Things” or IoT—which was exploited to help shut down parts of the Web this past Friday—is about to get a lot bigger, and fast. Christmas and Hanukkah wish lists are sure to be filled with smartwatches, fitness trackers, home-monitoring cameras and other wi-fi–connected gadgets that connect to the internet to upload photos, videos and workout details to the cloud. Unfortunately these devices are also vulnerable to viruses and other malicious software (malware) that can be used to turn them into virtual weapons without their owners’ consent or knowledge.

The recent distributed denial of service (DDoS) attacks—in which tens of millions of hacked devices were exploited to jam and take down internet computer servers—is an ominous sign for the Internet of Things. A DDoS is a cyber attack in which large numbers of devices are programmed to request access to the same Web site at the same time, creating data traffic bottlenecks that cut off access to the site.

Mayaro causes a disease that is clinically indistinguishable from the mosquito-borne chikungunya virus: fever, chills, rash and the characteristic joint pain that can last longer than a year. It does matter, though, which of these viruses circulates in your body. Once there are vaccines against Mayaro and chikungunya, and drugs to treat them (so far there are none), they will likely be virus-specific.

How Israel is Saving the Honeybees

Honeybees across the world are in a sticky situation. Their numbers are dwindling dramatically due to colony collapse disorder (CCD) for reasons that are not fully understood. Yet the honeybee population in Israel is holding steady.

That’s great news at this time of year, when sweet Jewish New Year dishes push honey demand to its peak. And most importantly, bees play a crucial role in agriculture by pollinating vegetables and fruits.

Israel takes measures to ensure that its bee population declines no more than 10 percent each year, compared to 30%-50% in the United States, where the problem is so severe that Häagen-Dazs ice cream has donated $1 million to honeybee research since 2008, and President Obama initiated a national strategy to promote bee health.

Back then the safe bet was to guess that the discovery of such a planet would only come after many decades, and that when a promising new world’s misty shores materialized on the other side of our telescopes, it would prove too faraway and faint to study in any detail.

Evidently the safe bet was wrong. On Wednesday astronomers made the kind of announcement that can only occur once in human history: the discovery of the nearest potentially habitable world beyond our solar system. This world may be rocky like ours and whirls in a temperate orbit around the sun’s closest stellar neighbor, the red dwarf star Proxima Centauri just over four light-years away. Their findings are reported in a study in Nature. Read more ..

Searching for a parking spot can be quite annoying. In particular in urban areas, motorists waste lots of time and fuel on the search for a place where they can leave their vehicle - for a couple of minutes or overnight. A test project in Munich currently puts a radar-based sensor network through its paces that could help drivers to find a parking spot faster and easier.

Motorists in places like Paris, London or Rome are familiar the situation: To find a free parking spot, drivers have to go for miles; at average it takes 4.5 kilometres. According to a recent study from Apcoa, up to 30 percent of the traffic in cities today are accounted to searching for parking lots. A network of radar sensors mounted on lamp post now is the basis for a smart parking management solution currently tested in Munich.

Connected Car: Dramatic growth ahead

August 9th 2016

Already in a few years, the number of connected cars out on the roads will reach a quarter billion. Market research and IT consultant firm Gartner predicts a dramatic growth - and many new business opportunities for hardware and software vendors.

The IoT is currently the big thing in technology, and the automotive version of the IoT is the Connected Car. No wonder the growth is similarly astronomic - and now Gartner came up with figures. By 2015 (that is, during the current year), the number of connected things will reach 4,9 billion units - up 30 percent from 2014. By 2020, this figure will quintuple to 25 billion units, believes Gartner. In this picture, connected cars are a major element. "The connected car is already a reality", said Gartner research director James F. Hines. "and in-vehicle wireless connectivity is rapidly expanding from luxury models and premium brands to high-volume mid-market models."

Car Hacking Remains a Viable Threat

August 4th 2016

In last year’s hack, which led to Chrysler’s recall for 1.4 million vehicles, Miller and Valasek focused on pulling off “wireless attack” on the Jeep.

The two at that time exploited a Harman “head unit,” which offers a Wi-Fi hot spot — in a 2014 Jeep Cherokee — to get into the vehicle’s network. Later the hackers invaded the car through its cellular connection, via Sprint’s wireless network.

This year, the security experts turned their attention to injecting rogue messages into a vehicle’s CAN bus, which resulted in a full-speed attack on the Jeep’s steering and acceleration.

Instead of getting into the guts of a car wirelessly, Miller and Valasek this year used a laptop directly plugged into the Jeep’s CAN network through a port under its dashboard. They confirmed that they used the patched Jeep for this hacking. Read more ..

Battery Technology Drives E-Bike Boom

July 14th 2016

Battery-single-use

Improvements in lithium ion battery technology are driving a boom in electric bicycle shipments around the world says a new report from market researchers Navigant Research.

Increasing urbanization and a desire to move away from cars for motorized transportation are creating more opportunities for alternative mobility devices such as e-bikes which will be the highest selling electric vehicle globally with nearly 35 million units sold this year. Navigant predicts the market will grow from $15.7 bn this year to $24.3 billion by 2025.

“Rising levels of population density and traffic congestion are driving interest in different modes of transportation,” says Ryan Citron, research analyst at Navigant Research. “E-bikes are uniquely positioned to be a primary benefactor of this trend since they are low in cost relative to cars, do not require licenses to operate, and can take advantage of existing bicycling infrastructure.”

The Edge of the Solar System

Juno Arrives at Jupiter

July 8th 2016

Jupiter

NASA's Juno spacecraft has successfully entered orbit around Jupiter. At 8:53 P.M. Pacific time, ground controllers received a telemetry tone of 2,327 hertz -- equivalent to the highest D note on a piano keyboard—indicating that Juno's 35-minute engine burn had slowed the spacecraft enough to slip into the giant planet’s gravitational embrace. Launched in 2011 on a nearly five-year interplanetary voyage, Juno is only the second spacecraft to ever orbit Jupiter, after the Galileo mission that explored the giant planet from 1995 to 2003. During its capture into orbit Juno passed just 4,490 kilometers above the Jovian cloud tops, so close that the planet filled half its sky. Even so, Jupiter is so immense that an astronaut riding along would have seen only about 5 percent of the planet’s cloud-shrouded face.

At 9:50 P.M., the maneuver was officially complete as the spacecraft turned its solar arrays back toward the sun. “I won't exhale until we’re sun-pointed again,” Juno's principal investigator Scott Bolton had said at a press conference earlier in the day.

The spacecraft plummeted in from interplanetary space over Jupiter's north pole at about 7:30 P.M., falling ever faster as it plunged deeper into the planet’s gravitational field. Just two days ago its speed relative to Jupiter was nine kilometers per second; midday yesterday, 12 kilometers per second; and by the rocket burn, 54 kilometers per second. The burn reduced its speed by just 1 percent, but that was enough. (Theoretically, the spacecraft was captured by the planet at 8:38 P.M., about halfway through the burn, but confirmation did not come until later.) After skimming so close to Jupiter's upper atmosphere, the spacecraft soared back up from the planet’s cloud tops at about 9:30 P.M. into a looping, elongated orbit out to 8.1 million kilometers.
