The analyses of an international team of researchers led by
Svante Pääbo of the Max Planck Institute for Evolutionary Anthropology in
Leipzig, Germany, show that the genetic variation of Denisovans was extremely
low, suggesting that although they were present in large parts of Asia, their
population was never large for long periods of time. In addition, a
comprehensive list documents the genetic changes that set apart modern humans
from their archaic relatives. Some of these changes concern genes that are
associated with brain function or nervous system development.

Study Links Math Abilities to Left-Right Brain Communication
Proficiency in Calculation Requires Efficient Neural Signals
Between Separate Cortex Areas
A new study by researchers at UT Dallas’ Center for Vital
Longevity, Duke University, and the University of Michigan has found that the
strength of communication between the left and right hemispheres of the brain
predicts performance on basic arithmetic problems. The findings shed light on the neural basis
of human math abilities and suggest a possible route to aiding those who suffer
from dyscalculia— an inability to understand and manipulate numbers.
Unexpected Finding Shows Climate Change Complexities in Soil
In a surprising finding, North Carolina State University
researchers have shown that certain underground organisms thought to promote
chemical interactions that make the soil a carbon sink actually play a more
complex, dual role when atmospheric carbon levels rise.
In a paper published in the Aug. 31 edition of Science,
North Carolina State University researchers show that important and common soil
microscopic organisms, arbuscular mycorrhizal fungi (AMF), play a role in
sequestering carbon below ground, trapping it from escaping into the atmosphere
as a greenhouse gas.
Plants' fungi allies may not help store climate change's extra carbon
Fungi found in plants may not be the answer to mitigating
climate change by storing additional carbon in soils as some previously
thought, according to an international team of plant biologists.
The researchers found that increased carbon dioxide
stimulates the growth of arbuscular mycorrhizal fungi (AMF) -- a type of fungus
that is often found in the roots of most land plants -- which then leads to
higher decomposition rates of organic materials, said Lei Cheng, post doctorate
fellow in plant science, Penn State. This decomposition releases more carbon
dioxide back into the air, which means that terrestrial ecosystems may have
limited capacity to halt climate change by cleaning up excessive greenhouse
gases, according to the researchers.
Photonic Interactions at the Atomic Level
By measuring the unique properties of light on the scale of
a single atom, researchers from Duke University and Imperial College, London,
believe that they have characterized the limits of the ability of metals to be
used in devices that rely on the enhancement of light.
This field is known as plasmonics because scientists are
trying to take advantage of plasmons, electrons that have been “excited” by
light in a phenomenon that produces electromagnetic field enhancement. The
enhancement achieved by means of metals at the nanoscale is significantly
higher than that achievable with any other material.
Information Overload? Overwhelmed by instant access to news and information? Most Americans like it
Overwhelmed by instant access to news and information? Most
Americans like it
“Information overload” may be an exaggerated way to describe
today’s always-on media environment. Actually, very few Americans seem to feel
bogged down or overwhelmed by the volume of news and information at their
fingertips and on their screens, according to a new Northwestern University
study.
The study was published in the journal The Information
Society.
“Little research has focused on information overload and
media consumption, yet it’s a concept used in public discussions to describe
today’s 24/7 media environment,” said Eszter Hargittai, an associate professor
of communication studies at Northwestern and lead author of the study.
'Nanoresonators' might improve cell phone performance
Researchers have learned how to mass produce tiny mechanical
devices that could help cell phone users avoid the nuisance of dropped calls
and slow downloads. The devices are designed to ease congestion over the
airwaves to improve the performance of cell phones and other portable devices.

Chinese Credit Card Usage Growing Quickly, MU Study Finds
In the past two decades, the Chinese economy has undergone
many drastic reforms in an effort to compete more effectively on the
international market. These reforms included allowing foreign banks to offer
credit cards to Chinese citizens. Now, researchers at the University of
Missouri have found about 30 percent of Chinese urban households now own at
least one credit card and the growth rate of credit card adoption has been an
average of 40 percent per year between 2004 and 2009.
Study finds gene that predicts happiness in women
New finding may help explain the gender difference in
happiness
A new study has found a gene that appears to make women
happy, but it doesn’t work for men. The finding may help explain why women are
often happier than men, the research team said.
Scientists at the University of South Florida (USF), the
National Institutes of Health (NIH), Columbia University and the New York State
Psychiatric Institute reported that the low-expression form of the gene monoamine oxidase A (MAOA)
is associated with higher self-reported happiness in women. No such association was found in men.
The findings appear online in the journal Progress in
Neuro-Psychopharmacology & Biological Psychiatry.
Pretend Play May Not Be as Crucial to Child Development as Believed, New Study Shows
Pretend play can be fun for preschool children, but a new
University of Virginia study, published in the current online edition of the
journal Psychological Bulletin, finds that it is not as crucial to a child's
development as currently believed. Pretend play is any play a child engages in,
alone, with playmates, or with adults, that involves uses of the imagination to
create a fantasy world or situation, such as making toy cars go “vrrooooom” or
making dolls talk.
Based on a number of key studies over four decades, pretend
play is widely considered by psychologists – and teachers and parents – to be a
vital contributor to the healthy development of children's intellect.
Beliefs Drive Investors More than Preferences, Study Finds
If experts thought they knew anything about individual
investors, it was this: their emotions lead them to sell winning stocks too
soon and hold on to losers too long.
But new research casts doubt on this widely held theory that
individual investors’ decisions are driven mainly by their feelings toward
losses and gains. In an innovative study, researchers found evidence that
individual investors’ decisions are primarily motivated by their beliefs about
a stock’s future.
Magnetic Vortex Reveals Key to Spintronic Speed Limit
Scientists measured a key effect of electron spin essential
to engineering the next generation of high-performing digital devices
The evolution of digital electronics is a story of
miniaturization – each generation of circuitry requires less space and energy
to perform the same tasks. But even as high-speed processors move into handheld
smart phones, current data storage technology has a functional limit:
magnetically stored digital information becomes unstable when too tightly
packed. The answer to maintaining the breath-taking pace of our ongoing
computer revolution may be the denser, faster, and smarter technology of
spintronics.

New Japanese solar development consortium plans 250 plants
Japan Mega Solar Co, a company created by Japanese home
renovator West Holdings, plan to invest 100 billion yen (USD1.27-billion) in
developing 250 small-scale solar plants with a combined capacity of 500-MW. The
projects are to be developed over five years.
West Holdings is not the only major Japanese company moving
into large-scale photovoltaic development, Noriaki Yamashita, a senior
researcher at the Institute for Sustainable Energy Policies told PV magazine.
He reported that in July more than 40 big companies announced plans to do so,
representing "a very big tide for the renewable energy industry."
The next major patent skirmish is already here
So-called LTE networks promise to dramatically speed up the
mobile Internet. Too bad patent squabbles may muck things up.
FORTUNE -- As dramatically shown in Apple and Samsung's epic
legal conflict, patents have become the new currency among tech giants.
Dull-sounding legal instruments have become all-important, not necessarily
because of their financial worth but for their strategic and marketing value.
Simply put, patents are a means to gaining a competitive advantage.
Don’t Let Waste Go to Waste
Reduce. Reuse. Recycle.
It sounds simple. It’s not.
Just ask Bill Caesar, who runs the recycling and organic
growth units of Waste Management (WM), America’s biggest trash company, which
has $13.3 billion in revenues last year.
It’s hard to get many cities and towns to embrace recycling.
It’s hard to get homeowners to figure out which plastics go
into which bin.
It’s expensive to build out the infrastructure needed to
separate materials, and ship them to customers.
Acta develops new alkaline electrolyzer that could make hydrogen more viable
Acta unveils new electrolyzers
Italy’s Acta S.p.A, a developer of hydrogen generation
systems, has developed a new alkaline membrane electrolyzer that is not reliant
on a catalyst made of platinum or iridium. The company suggests that this new
electrolyzer could cost only a third as much as more conventional models that
rely on catalysts using expensive materials. Acta notes that it has developed
the only other electrolyzer that currently exists in the hydrogen market,
putting the company in a strong position to have a profound impact on the fuel
cell industry as a whole.
Motor manufacturers accelerate vehicle carbon cuts
Figures show almost half of the major car companies' fleets
already have average emissions below the 2015 limit of 130g of CO2 per km
Car manufacturers continue to make progress towards EU
carbon emissions targets, with almost half already achieving the 2015
benchmark.
Figures from analysts Redspy published last week show that
by July this year the fleets of 15 of the 31 major European manufacturers
already had average emissions below the 130 grams of CO2 per kilometre mark
that will become compulsory by 2015
However, manufacturers are still a way short of the 2020
target, which will require average emissions to have fallen to 95g/km.

capable of significantly reducing the nation’s need for foreign crude oil,
which will serve as the blueprint for scalable algae biofuel facilities
globally.
‘Frankenstein’ Programmers Test a Cybersecurity Monster
UT Dallas Researchers Hope Software Helps Develop Defenses
Against New Kinds of Attacks
UT Dallas computer scientists are trying to stay one step
ahead of cyberattackers by creating their own monster. Their monster can cloak
itself as it steals and reconfigures information in a computer program.
In part because of the potentially destructive nature of
their technology, creators have named this software system Frankenstein, after
the monster-creating scientist in author Mary Shelley’s novel, Frankenstein, or
The Modern Prometheus.

Light from Self-Luminous Tablet Computers Can Affect Evening Melatonin, Delaying Sleep
Depending on How Much and How Long, Light from Self-Luminous
Tablet Computers Can Affect Evening Melatonin, Delaying Sleep
New LRC research can aid in the development of
“circadian-friendly” electronic devices
A new study from the Lighting Research Center (LRC) at
Rensselaer Polytechnic Institute shows that a two-hour exposure to electronic
devices with self-luminous “backlit” displays causes melatonin suppression,
which might lead to delayed bedtimes, especially in teens.
A Lesson in Sleep Learning
Is sleep learning possible? A new Weizmann Institute study
appearing today in Nature Neuroscience online has found that if certain odors
are presented after tones during sleep, people will start sniffing when they
hear the tones alone – even when no odor is present – both during sleep and,
later, when awake. In other words, people can learn new information while they
sleep, and this can unconsciously modify their waking behavior.
Merging tissue and electronics
New tissue scaffold could be used for drug development and
implantable therapeutic devices.
To control the three-dimensional shape of engineered tissue,
researchers grow cells on tiny, sponge-like scaffolds. These devices can be
implanted into patients or used in the lab to study tissue responses to
potential drugs.
Climate Change
An Information Statement of the American Meteorological
Society
The following is an AMS Information Statement intended to
provide a trustworthy, objective, and scientifically up-to-date explanation of
scientific issues of concern to the public at large.
Background
This statement provides a brief overview of how and why
global climate has changed over the past century and will continue to change in
the future. It is based on the peer-reviewed scientific literature and is
consistent with the vast weight of current scientific understanding as
expressed in assessments and reports from the Intergovernmental Panel on
Climate Change, the U.S. National Academy of Sciences, and the U.S. Global
Change Research Program. Although the statement has been drafted in the context
of concerns in the United States, the underlying issues are inherently global
in nature.

Controlling Superconductors with Light
TAU researcher discovers that a ray of light could lead to
the next generation of superconductors
A superconductor, which can move electrical energy with no
wasteful resistance, is the holy grail of cost-effective, efficient, and
"green" power production. Unlike traditional conductors such as
copper or silver, which waste power resources and lose energy when they heat
up, an ideal superconductor would continuously carry electrical current without
losing any power.

Cooled coal emissions would clean air and lower health and climate-change costs
Refrigerating coal-plant emissions would reduce levels of
dangerous chemicals that pour into the air — including carbon dioxide by more
than 90 percent — at a cost of 25 percent efficiency, according to a simple
math-driven formula designed by a team of University of Oregon physicists.
The computations for such a system, prepared on an
electronic spreadsheet, appeared in Physical Review E, a journal of the

The Laser Beam as a “3D Painter”
With laser beams, molecules can be fixed at exactly the
right position in a three dimensional material. The new method developed at the
Vienna University of Technology can be used to grow biological tissue or to
create micro sensors.
There are many ways to create three dimensional objects on a
micrometer scale. But how can the chemical properties of a material be tuned at
micrometer precision? Scientists at the
Vienna University of Technology developed a method to attach molecules at
exactly the right place. When biological tissue is grown, this method can allow
the positioning of chemical signals, telling living cells where to attach. The
new technique also holds promise for sensor technology: A tiny three
dimensional “lab on a chip” could be created, in which accurately positioned
molecules react with substances from the environment.
How methane becomes fish food
Methane produced at the bottom of our lakes provides
nutrition for microorganisms and eventually becomes an indirect food source for
fish. These findings were presented in a one of a kind study that contradicts
previous perceptions of lakebed sediment methane stores being lost in the food
chain.
Methane is an organic carbon compound containing the
fundamental building block of nearly all living material: carbon. It provides
an important source of energy and nutrients for bacteria. Methane is produced
in oxygen-free environments and is found in abundance at the bottom of lakes.

System Research with the High Altitude and Long Range Research Aircraft”.
Nanoparticles reboot blood flow in brain
A nanoparticle developed at Rice University and tested in
collaboration with Baylor College of Medicine (BCM) may bring great benefits to
the emergency treatment of brain-injury victims, even those with mild injuries.
Combined polyethylene glycol-hydrophilic carbon clusters
(PEG-HCC), already being tested to enhance cancer treatment, are also adept
antioxidants. In animal studies, injections of PEG-HCC during initial treatment
after an injury helped restore balance to the brain’s vascular system.
The results were reported this month in the American
Chemical Society journal ACS Nano.
Merging the biological, electronic
Researchers grow cyborg tissues with embedded
nanoelectronics
Harvard scientists have created a type of “cyborg” tissue
for the first time by embedding a three-dimensional network of functional,
biocompatible, nanoscale wires into engineered human tissues.
As described in a paper published Aug. 26 in the journal
Nature Materials, a research team led by Charles M. Lieber, the Mark Hyman Jr.
Professor of Chemistry at Harvard, and Daniel Kohane, a Harvard Medical School
professor in the Department of Anesthesia at Children’s Hospital Boston,
developed a system for creating nanoscale “scaffolds” that can be seeded with
cells that grow into tissue.
Vitamin B12 deficiency: tracking the genetic cause
Some people have inherited conditions that leave them unable
to process vitamin B12.
Vitamin B12 is essential to human health. However, some
people have inherited conditions that leave them unable to process vitamin B12.
As a result they are prone to serious health problems, including developmental
delay, psychosis, stroke and dementia. An international research team recently
discovered a new genetic disease related to vitamin B12 deficiency by
identifying a gene that is vital to the transport of vitamin into the cells of
the body.
Stanford researchers discover the 'anternet'
A collaboration between a Stanford ant biologist and a
computer scientist has revealed that the behavior of harvester ants as they
forage for food mirrors the protocols that control traffic on the Internet.
On the surface, ants and the Internet don't seem to have
much in common. But two Stanford researchers have discovered that a species of
harvester ants determine how many foragers to send out of the nest in much the
same way that Internet protocols discover how much bandwidth is available for
the transfer of data. The researchers are calling it the "anternet."
New wave of technologies possible after ground-breaking analysis tool developed

Long Endurance Multi-Intelligence Vehicle (LEMV)
The Army has deployed several tethered aerostats, including
the Persistent Threat Detection System (PTDS) and the JLENS Rapid Aerostat
Initial Deployment (RAID) system. A new hybrid airship weapons system, just
larger than the length of a football field, will take to the skies to provide
an unblinking, persistent eye for more than three weeks at a time to aid US
Army troops in Afghanistan. Northrop Grumman Corporation was awarded on June
14, 2010 a $517 million agreement to develop up to three Long Endurance
Multi-Intelligence Vehicle (LEMV) systems for the US Army. Northrop Grumman has
designed a system with plug-and-play capability to readily integrate into the
Army's existing common ground station command centers and ground troops in
forward operating bases - the main objective to provide US warfighters with
persistent ISR capability to increase awareness of the ever changing
battlefield.

Trident Iceni Diesel Grand Tourer Coming To Salon Privé 2012
As far as sports and GT cars are concerned, the British and
the Italians are best. However, while the Italians may have the likes of
Ferrari and the rest, Britain has a myriad of small ‘shed-based’ manufacturers
which make unique cars for people looking for a very specific kind of car.
Take the £75,000 (€94,880 / $119,160) Trident Iceni, a
hand-built car which is very British and truly interesting. It is a two-seater
GT cruiser, with its big 6.6-liter V8 engine mid-mounted behind the front axle.
It produces 430 hp and 1290 Nm (950 lb-ft), yet those figures can be boosted to
660 hp and 1420 Nm (1050 lb-ft) with an available engine upgrade.
This monster of an engine allows the Iceni to sprint from
0-100 km/h (0-62 mph) in under 4 seconds and on to a top speed of around 320
km/h (200 mph). Furthermore, if a constant speed of 110 km/h (70 mph) is
maintained, the engine will only turn over at some 980 rpm, allowing the car to
achieve an incredible efficiency figure for such a big engine - 4.1 l/100km or
68.9 UK mpg, allowing it to travel as much as 3,200 km (2000 miles) on a
tankfull of regular diesel, mineral diesel, bio diesel, palm oil or linseed
oil.
Trident Sports Cars managing director, Phillip Bevan, says:
“We are very pleased to be at Salon Privé which this year is a great
celebration of all things British and home grown talent - something we feel
very strongly about at Trident. It is
also a place where sports cars and super cars of this calibre are sold, and we
look forward to taking new orders for the Iceni at Syon Park this September.”
The 21st century hovercraft: Designers create sports car-inspired design

Recycled beer bottles used to construct Las Vegas building
Las Vegas is also known as Sin City for its over the top
glitz, the way it appears to promote glamour over everything else and its
promotion of the indulgence of one’s senses to the point of being gluttonous.
By its apparent promotion of vices, being eco-friendly is perhaps the last
thing on the minds of builders which is exactly why the Morrow Royal Pavilion
stands out as a beacon of eco-righteousness in Las Vegas.
Used as a manufacturing facility, the building is made
entirely from recycled beer bottles. All the bottles used in the structure were
collected by Realm of Design from hotels located near the Las Vegas Strip. The
project was commissioned by Scott McCombs, an entrepreneur, and was inspired by
England’s Swarkestone Hall Pavilion. With a 30,000-square-foot of floor space
inside, the structure is already being dubbed the largest building in the world
constructed from recycled bottled.
UbiCiT electric monorail caters to Montreal’s growing transportation needs
Montreal is growing and developing fast, and so is the need
for urban public transportation systems that are light on the environment but
could manage the growing needs. Industrial designer Frederic Laurin-Lalonde from the University of Montreal has come up
with a concept electric monorail, which is perfectly suited for the city.
Christened the UbiCiT, the electric monorail is proposed for
the first phase of Quebec network of monorail that extends from Montreal to its
southern suburbs. The electric monorail, which is designed to be suspended
either meters above the ground, will be highly energy efficient and can easily
carry 300 people, while still allowing access to people with reduced mobility
and those who come to the station riding their bikes.
Since the concept has been designed to be suspended directly
above existing roads and highways, local people will still be able to use the
space below, while admiring the monorail passing right over their heads. The
design has been made as aerodynamic as possible, so that only a small
percentage of electricity is consumed to overcome drag and the monorail can zip
past as fast as possible.
Sydney to London on plastic fuel
Sydney is the departure point of the world's first flight
using a fuel made from “end of life” plastic. Later this year British pilot
Jeremy Rowsell plans to fly back home from Australia in a single engine Cessna,
which normally runs on diesel, according to a report by Business Green.
The experimental fuel used during the journey is made by
melting plastic waste in an oxygen-free environment; a process known as
pyrolysis. The distillate can be separated different fuels, such as gasoline,
diesel and kerosene, which have low sulfur and high cetane qualities.
It is being produced by an Irish company Cynar Plc, which believes that with the
quantity of waste plastic available, there is a ready market for its “End of
Life Plastic to Diesel” (ELPD) process. It points out that US dumps 26 million
tonnes of plastics into landfill each year and Europe throws away another 15
million tonnes.
The company claims that at the present level of development
its process can produce up to 19,000 liters of fuel from 20 tonnes of waste,
with the balance of material being turned into carbon char.
Cynar is actively seeking partners with experience in the
waste and fuel industries to work together in rapidly commercializing it
technology.
The first full scale ELPD is operating in Ireland and Cynar
a £70m (USD111 million) contract with SITA/SuezEnvironment to build 10 more, the first of which has received planning
permission in the UK.
Engineering students build UK's first hydrogen powered locomotive
Engineering students and staff at the University of
Birmingham have designed and built a prototype hydrogen powered locomotive, the
first of its kind to operate in the UK.
This narrow gauge locomotive is a hybrid design, combining a
hydrogen fuel cell and lead acid batteries similar to the ones used in cars.
The fuel cell is used both to power the permanent magnet electric motors and to
charge the batteries, with the batteries helping to meet the peak power demands
when accelerating under load.

Sunbathing keeps these insects healthy – study
Western Boxelder bugs (WBB), found largely in B.C. interior
regions, are known to group together in sunlit patches and while there, release
monoterpenes, strong-smelling chemical compounds that help protect the bugs by
killing germs on their bodies.
Researchers previously thought the compounds had a role in
reproduction or defending the bugs against predators. But their latest study
found that the compounds were emitted when the bugs were in sunshine – in
effect, sunbathing – and weren’t used for communication or other purposes.
Researchers Develop Simplified Approach for High-Power, Single-Mode Lasers
When it comes to applications like standoff sensing — using
lasers to detect gas, explosives, or other materials from a safe distance — the
laser’s strength is of the utmost importance. A stronger and purer beam means
devices can sense danger more accurately from a greater distance, which
translates into safer workers, soldiers, and police officers.
