|The prototype AshPoopie, targeted for retail in 2012.|
Coming to pet shops in 2012: An Israeli pooper-scooper that turns droppings into harmless, odorless ash within seconds.
If you have a dog, then you know that no matter how fancy a pooper-scooper you've got, after Rover's walk you are still left with a messy, smelly nuisance that pollutes the environment with sewage and plastic bags.
One Israeli who got fined for failing to pick up the droppings decided to contact Prof. Oded Shoseyov of the Hebrew University, a renowned biotech inventor, for a better solution. And Shoseyov rose to the challenge.
His novel idea is AshPoopie, a pooper-scooper with a critical difference: After it gathers the droppings, it turns them into odorless, sterile ash within seconds. All the dog-walker has to do is push a button to release an activation capsule from the cartridge inside the unit. Read more ..

Despite booming growth in data revenue, margins for wireless operators have been squeezed as they have been slow to react to the paradigm shift wrought by the explosive rise of broadband usage on smartphones and tablets, forcing the operators to embrace new revenue services and business models—including the cloud—to enhance profits, according to the IHS iSuppli.
“Mobile communications service providers have lagged behind in the race to unlock the value in the mobile communications industry, which is estimated to grow to a trillion dollars during the next two years,” said Jagdish Rebello, Ph.D., senior director and principal analyst for communications and consumer electronics at IHS.

Apple's latest iPhone - the iPhone 4S - may share many similarities to the iPhone 4, but it also features several notable upgrades, including a major upgrade to the applications processor, the use of a higher-resolution and more advanced camera module and the addition of a new cellular radio that makes the iPhone 4S a true "world phone," according to market research firm IHS iSuppli.
Apple has disclosed that the iPhone 4S features its dual-core A5 processor - the same processor found in iPad 2 - an upgrade from the single-core A4 found in iPhone 4 and other previous products. According to IHS' preliminary analysis based on features announced by Apple, iPhone 4S likely has the same 4-Gb SDRAM memory configuration found in iPad 2.
The use of this low density of memory highlights the efficiency of Apple’s iOS operating system compared to those of competitive smartphones, which use twice as much SDRAM, at 8 Gb IHS said. This lowers the cost of this memory subsystem, leading to greater design economy relative to alternative phones, according to IHS. Read more ..

Chicago will need approximately 84,500 small cells to deliver truly high-speed LTE by 2015, with acceptable coverage and speeds, according to analysis from Picochip. To provide LTE everywhere in the US around 1.8 million small cells would be required, based on estimations on data growth and usage across the country. This is in addition to residential femtocells and Wi-Fi.
The analysis models what will be required to deliver the advertised data rates consistently to users wherever they are. The capacity per cell is based on extensive simulations of traffic from projected device populations and traffic service types in 2015, incorporating propagation models and calculations of network efficiency and loading. Around 20,000 of the small cells needed for Chicago would be installed in malls and retail premises where demand for data is often highest. Other sites include airports, stations, office buildings and outdoor sites providing wider coverage in busy street areas.
The report was put together by Picochip’s CTO Dr. Doug Pulley, who also concluded that worldwide there would need to be in excess of ten million small cells to deliver comparable performance. Read more ..

North American forests appear to have a greater capacity to soak up heat-trapping carbon dioxide gas than researchers had previously anticipated.
As a result, they could help slow the pace of human-caused climate warming more than most scientists had thought, a University of Michigan ecologist and his colleagues have concluded.
The results of a 12-year study at an experimental forest in northeastern Wisconsin challenge several long-held assumptions about how future forests will respond to the rising levels of atmospheric carbon dioxide blamed for human-caused climate change, said University of Michigan microbial ecologist Donald Zak, lead author of a paper published online this week in Ecology Letters.
"Some of the initial assumptions about ecosystem response are not correct and will have to be revised," said Zak, a professor at the U-Michigan School of Natural Resources and Environment and the Department of Ecology and Evolutionary Biology in the Ann Arbor-based institution's College of Literature, Science, and the Arts.

Operational costs are on the rise at global technology companies' Indian R&D centers as the focus shifts from cost cutting to innovation and value creation, a recent study found.
Zinnov Management Consulting reported that R&D operational costs are on course for a 9 percent year-on-year increase—13 percent in U.S. dollar terms—in 2011, following two years of stringent cost reductions.
Operational costs next year are expected to rise between 8 and 12 percent, the consultancy projects. Attrition among employees at the country's 700 R&D centers has been as high as 20 percent this year, companies told Zinnov analysts, while salaries have increased between 10 and 15 percent.

The Race for Wind
|Julia Harte||October 15th 2011|
The lights in Akbıyık went out one and a half years ago, when the Turkish Electricity Distribution Company cut off the village’s electricity because of outstanding utility bills that amounted to TRY 33,000 ($18,000). At that point, the villagers faced a choice: pay off the debt and get back on the national power grid, or find a new energy source that they could harness and control on their own.
They chose to stay off the grid and switch to wind power, securing their energy future and making them one of the greenest villages in Turkey.
A carefully researched decision
Akbıyık’s residents and village headman researched various forms of renewable energy before settling on wind power. They proposed a TRY 160,000 wind turbine project to the government of their province, Bursa. The villagers contributed TRY 20,000, but the majority of the initial costs were paid by the Bursa Provincial Administration. Read more ..

The space between the galaxies wasn't always transparent. In the earliest times, it was an opaque, dense fog. How it cleared is an important question in astronomy. New observational evidence from the University of Michigan shows how high energy light from massive stars could have been responsible.
Astronomers believed that early star-forming galaxies could have provided enough of the right kind of radiation to evaporate the fog, or turn the neutral hydrogen intergalactic medium into the charged hydrogen plasma that remains today. But they couldn't figure out how that radiation could escape a galaxy. Until now.
Jordan Zastrow, a doctoral astronomy student, and Sally Oey, a U-M astronomy professor, observed and imaged the relatively nearby NGC 5253, a dwarf starburst galaxy in the southern constellation Centaurus. Starburst galaxies, as their name implies, are undergoing a burst of intense star formation. While rare today, scientists believe they were very common in the early universe. Read more ..

Researchers led by MIT professor Daniel Nocera have produced something they call an "artificial leaf": Like living leaves, the device can turn the energy of sunlight directly into a chemical fuel that can be stored and used later as an energy source.
The artificial leaf - a silicon solar cell with different catalytic materials bonded onto its two sides - needs no external wires or control circuits to operate. Simply placed in a container of water and exposed to sunlight, it quickly begins to generate streams of bubbles: oxygen bubbles from one side and hydrogen bubbles from the other. If placed in a container that has a barrier to separate the two sides, the two streams of bubbles can be collected and stored, and used later to deliver power: for example, by feeding them into a fuel cell that combines them once again into water while delivering an electric current.
The device, Nocera explains, is made entirely of earth-abundant, inexpensive materials - mostly silicon, cobalt and nickel - and works in ordinary water. Other attempts to produce devices that could use sunlight to split water have relied on corrosive solutions or on relatively rare and expensive materials such as platinum.

Steve Jobs, co-founder of Apple and the holder of more than 300 technology patents, died on October 5. The eccentric entrepreneur who built Apple into the world’s leading technological company started in a prosaic garage in Silicon Valley. Having built one of the first personal computers marketed, Jobs led Apple to create wildly popular devices such as the iPhone. He was 56.
Sometimes accused of egocentricity, Jobs pioneered the concept of the personal computer and of navigating them by clicking onscreen images with a mouse, which he also developed. In more recent years, Jobs introduced the iPod portable music player, the iPhone and the iPad tablet, which changed how content is accessed and consume in the digital age. "Steve Jobs is one of the great innovators in the history of modern capitalism," New York Times columnist Joe Nocera said in August. "His intuition has been phenomenal over the years." Read more ..

The U.S. space agency, NASA, says there are slightly fewer massive, planet-buster asteroids and far fewer mid-sized, city-buster asteroids than previously thought in near-Earth orbit. The findings were the latest from NASA's asteroid-hunter, the Wide-field Infrared Survey Explorer, known as WISE.
Imagine a census of the inner solar system. Specifically, imagine a count of asteroids that orbit within 195 million kilometers of the Sun into Earth's orbital vicinity.
This is a population that fascinates Amy Mainzer of NASA's Jet Propulsion Laboratory in California. She is the principal investigator for the near-Earth Orbit Wide-field Infrared Survey Explorer, or NEOWISE.
"As one of my colleagues at the Jet Propulsion Laboratory likes to say, 'the best three ways of dealing with the potential of an asteroid impact are to find them early, find them early and find them early,'" Mainzer said. Read more ..

More than three million people visit Israel each year. More every month. They are tourists, pilgrims, businessmen, diplomats, students, and celebrants.
Most visitors to Israel are highly wired and connected individuals who need to stay in touch with home and business. But they also need to maximize their enjoyment of Israel's endless attractions. The problem is that getting connected in Israel is difficult. Naturally, your smartphones are going to become completely stupid in Israel due to incompatible signal. Therefore, any hookup for telephone is still going to require a global phone--very expensive, or a travel phone rental--less expensive.
The workaround for smartphone apps is your laptop or iPad. But your iPads and tablets will not work because you lack an Israeli wireless connection. When you finally connect at your hotel, the daily connect fee is often double or triple the cost of a typical US hotel fee—as much as $20 to $30 per day plus tax just to get connected. All this aggravation can be avoided with a small box about the size of a wallet--the mobile hotspot. It is offered by a recently formed Israeli hi-tech company called WeMakeIt. You will find it easily available on demand from the leading car rental company, Eldan, or delivered to your hotel. The fact that Eldan makes the mobile hotspot—or MiFi—as easily available as US rental agencies do for navigators, sets Israeli travel ease a notch ahead for ease and access. Read more ..

Antibiotic resistant E. coli was much more prevalent in villages situated along roads than in rural villages located away from roads, which suggests that roads play a major role in the spread or containment of antibiotic resistant bacteria, commonly called superbugs, a new study finds.
Many studies on various infectious diseases have shown that roads impact the spread of disease, however this is the first known study to show that roads also impact the spread of antibiotic resistant bacteria, said Joe Eisenberg, co-author and professor at the University of Michigan School of Public Health.
Researchers at the U-Michigan SPH and colleagues from Universidad San Francisco de Quito, and Trinity College studied a region in northwest Ecuador for five years, focusing on antibiotic resistant E. coli and the common antibiotic paring of ampicillin and sulfamethoxazole. Read more ..

Spanish researchers have designed what they believe to be a new type of magnetic cloak, which shields objects from external magnetic fields, while at the same time preventing any magnetic internal fields from leaking outside, making the cloak undetectable.
The development of such a device, described as an 'antimagnet', could offer many beneficial applications, such as protecting a ship's hull from mines designed to detonate when a magnetic field is detected, or allowing patients with pacemakers or cochlear implants to use medical equipment. In their study, published in the Institute of Physics and German Physical Society's New Journal of Physics, researchers have proved that such a cloak could be built using practical and available materials and technologies, and used to develop an array of applications.
Take, for example, a patient with a pacemaker undergoing an MRI scan. If an MRI's large magnetic field interacts with the pacemaker, it can cause serious damage to both the device and the patient. The metal in the pacemaker could also interact with and distort the MRI's large magnetic field, affecting the machine's detection capabilities.The researchers, from Universitat Autňnoma de Barcelona, are aware that the technology could also be used by criminals to dodge security systems, for example in airports and shops, but they are confident that the new research could benefit society in a positive way, while the risks could be minimized by informing security officials about potential devices, enabling them to anticipate and neutralize problems.

The fact that certain smells cause us pleasure or disgust would seem to be a matter of personal taste. But new research at the Weizmann Institute of Science shows that odors can be rated on a scale of pleasantness, and this turns out to be an organizing principle for the way we experience smell. The findings, which appeared September 26 in Nature Neuroscience, reveal a correlation between the response of certain nerves to particular scents and the pleasantness of those scents. Based on this correlation, the researchers could tell by measuring the nerve responses whether a subject found a smell pleasant or unpleasant.
Our various sensory organs have evolved patterns of organization that reflect the type of input they receive. Thus the receptors in the retina, in the back of the eye, are arranged spatially for efficiently mapping out visual coordinates. The structure of the inner ear, on the other hand, is set up according to a tonal scale. But the organizational principle for our sense of smell has remained a mystery: Scientists have not even been sure if there is a scale that determines the organization of our smell organ, much less how the arrangement of smell receptors on the membranes in our nasal passages might reflect such a scale.

Astronomers say they have discovered a planet that orbits around a pair of stars. It is the first time a so-called circumbinary system has been detected.
Movie fans might be familiar with “Star Wars, Episode IV: A New Hope,” the blockbuster movie from 1977. Luke Skywalker stands on his stark home planet Tatooine. As he gazes pensively into the distance toward a pinkish sky, an orange sun descends toward the horizon, with a smaller white sun following close behind.
Well, move over, Tatooine, says John Knoll of Industrial Light and Magic, which created the special effects for the Star Wars films.

Even when smartphones are in power-saving modes and not actively sending or receiving messages, they are still on alert for incoming information and they're searching for a clear communication channel. The researchers have found that this kind of energy-taxing "idle listening" is occurring during a large portion of the time phones spend in power-saving mode — as much as 80 percent on busy networks.

A robot in a University of Michigan lab can run like a human—a feat that represents the height of agility and efficiency for a two-legged machine. With a peak pace of 6.8 miles per hour, MABEL is believed to be the world's fastest bipedal robot with knees.
"It's stunning," said Jessy Grizzle, a professor in the Department of Electrical Engineering and Computer Science. "I have never seen a machine doing a motion like this."
MABEL was built in 2008 in collaboration with Jonathan Hurst, who was then a doctoral student at the Robotics Institute at Carnegie Mellon University. Grizzle and U-M doctoral students Koushil Sreenath and Hae-Won Park have spent the years since ratcheting up MABEL's training. They've been progressively improving the feedback algorithms that enable the robot to keep its balance while reacting to its environment in real time.
MABEL started off walking smoothly and quickly over flat surfaces. Then it moved on to uneven ground. It took its first real jog in late July, and with that, Sreenath met the ultimate goal of his research just days before he was scheduled to defend his thesis. Read more ..

Wiring systems powered by highly-efficient superconductors have long been a dream of science, but researchers have faced such practical challenges such as finding pliable and cost-effective materials. Now researchers at Tel Aviv University have found a way to make an old idea new with the next generation of superconductors.
Dr. Boaz Almog and Mishael Azoulay working in the group of Prof. Guy Deutscher at TAU's Raymond and Beverly Sackler School of Physics and Astronomy have developed superconducting wires using fibers made of single crystals of sapphire to be used in high powered cables. Factoring in temperature requirements, each tiny wire can carry approximately 40 times more electricity than a copper wire of the same size
High power superconductor cables take up much less space and conduct energy more efficiently, making them ideal for deployment across grids of electricity throughout a city. They will also offer a more effective method for collecting energy from renewable sources, such as solar and wind energy. Superconducting wires can also be used for energy storage and enable devices which enhance grid stability. Read more ..

Being able to count helps spotted hyenas decide to fight or flee, according to research at Michigan State University. When animals fight, the larger group tends to win.
In the current issue of Animal Behaviour, Sarah Benson-Amram, an MSU graduate student studying zoology, showed that hyenas listen to the sound of intruders’ voices to determine who has the advantage.
“They’re more cautious when they’re outnumbered and take more risks when they have the numerical advantage,” said Benson-Amram, who conducted the study through MSU’s BEACON Center for the Study of Evolution in Action. “Hyenas appear to be as capable as chimpanzees or lions at assessing their advantage.”
The finding supports the concept that living in complex social groups, as hyenas, lions and chimpanzees do, is one of the keys to the evolution of big brains, Benson-Amram added.
Even though spotted hyenas live in clans of up to 90 individuals, they spend much of the day in much smaller, more vulnerable groups. When researchers played recordings of potential intruders, the hyenas’ reaction depended on how many voices they heard compared to how many fellow pack members surrounded them. Groups of three or more hyenas were far more likely to approach the source of sound than pairs or individuals. Read more ..

For a few years now, scientists have known that humans and their evolutionary cousins had some casual flings, but now it appears that these liaisons led to a more meaningful relationship.
Sex with Neanderthals and another close relative — the recently discovered Denisovans — has endowed some human gene pools with beneficial versions of immune system genes, report researchers at the Stanford University School of Medicine in an article published online in Science Express.
Although modern humans, Neanderthals and Denisovans share a common ancestor in Africa, the groups split into separate, distinct populations approximately 400,000 years ago. The Neanderthal lineage migrated northwestward into West Asia and Europe, and the Denisovan lineage moved northeastward into East Asia. The ancestors of modern man stayed in Africa until 65,000 years or so ago, when they expanded into Eurasia and then encountered the other human-like groups. In some cases, the rendezvous were amorous in nature.
Last year, a partial genome sequence of Neanderthals, who died out approximately 30,000 years ago, revealed that these trysts left as much as 4 percent Neanderthal DNA in the genetic blueprint of some present-day humans. Last December, the genome of another human cousin, the extinct Denisovans, made clear that up to 6 percent of some people's genomes are Denisovan in origin. Read more ..

|Syed Hashsham demonstrates Gene-Z|
An engineering researcher and a global health expert from Michigan State University are working on bringing a low-cost, hand-held device to nations with limited resources to help physicians detect and diagnose cancer.
Syed Hashsham, a professor of civil and environmental engineering at MSU, is developing the Gene-Z device, which is operated using an iPod Touch or Android-based tablet and performs genetic analysis on microRNAs and other genetic markers. MicroRNAs are single-stranded molecules that regulate genes; changes in certain microRNAs have been linked to cancer and other health-related issues.
He is working with Reza Nassiri, director of MSU's Institute of International Health and an assistant dean in the College of Osteopathic Medicine, on the medical capabilities for the device and establishing connections with physicians worldwide.
Cancer is emerging as a leading cause of death in underdeveloped and developing countries where resources for cancer screening are almost non-existent, Nassiri said. Read more ..

Skewed skulls may have helped early whales discriminate the direction of sounds in water and are not solely, as previously thought, a later adaptation related to echo-location. University of Michigan researchers report the finding in a paper being published online in the Proceedings of the National Academy of Sciences.
Asymmetric skulls are a well-known characteristic of the modern whale group known as odontocetes (toothed whales). These whales also have highly modified nasal structures with which they produce high-frequency sounds for echolocation -- a sort of biological sonar used to navigate and find food. The other modern whale group, mysticetes (baleen whales), has symmetrical skulls and does not echolocate.
These observations led scientists to believe that archaeocetes -- the extinct, ancient whales that gave rise to all modern whales -- had symmetrical skulls, and that asymmetry later developed in toothed whales in concert with echolocation. But a new analysis of archaeocete skulls by U-Michigan postdoctoral fellow Julia Fahlke and coauthors shows that asymmetry evolved much earlier, as part of a suite of traits linked to directional hearing in water.

A delicate balance of atomic forces can be exploited to make nanoparticle superclusters that are uniform in size—an attribute that's important for many nanotech applications but hard to accomplish, University of Michigan researchers say. The same type of forces are at work bringing the building blocks of viruses together, and the inorganic supercluster structures in this research are in many ways similar to viruses.
U-Michigan chemical engineering professors Nicholas Kotov and Sharon Glotzer led the research. The findings are newly published online in Nature Nanotechnology.
In another instance of forces behaving in unexpected ways at the nanoscale, they discovered that if you start with small nanoscale building blocks that are varied enough in size, the electrostatic repulsion force and van der Waals attraction force will balance each other and limit the growth of the clusters. This equilibrium enables the formation of clusters that are uniform in size. Read more ..

Why do some folks who take every precaution still get the flu, while others never even get the sniffles?
It comes down to a person's immune system response to the flu virus, says Alfred Hero, professor at the University of Michigan College of Engineering. In one of the first known studies of its kind, Hero and colleagues from Duke University Medical Center and the Duke Institute for Genome Sciences & Policy, used genomics to begin to unravel what in our complex genomic data accounts for why some get sick while others don't. The study findings will appear in PLoS Genetics. Read more ..

A new Deloitte report states that wireless telecommunications companies in the United States could invest $25 to $53 billion in fourth generation cellular wireless networks (4G) between 2012 and 2016, triggering $73 to $151 billion in gross domestic product growth and creating 371,000 to 771,000 jobs. Additional growth could occur as high-tech companies create new mobile broadband products and services, further changing the way people live, work and learn.
The Deloitte report, "The Impact of 4G Technology on Commercial Interactions, Economic Growth, and U.S. Competitiveness," investigates the economic dynamics surrounding 4G technology and explains how the U.S. can maintain the global leadership position in mobile broadband innovation it won during the 3G era.
The $25 billion figure assumes a baseline scenario in which U.S. 4G deployment proceeds at a moderate pace and the transition from 3G to 4G extends to the middle of the decade. Under these conditions, U.S. firms are vulnerable to incursions by foreign competitors capitalizing on aggressive efforts in their home markets to deploy 4G networks and develop 4G-based devices and services.
