1. NIST
Releases Draft Roadmap for Cloud Computing
Technology
The National Institute of
Standards and Technology (NIST) has released for
public comment a draft "roadmap" that is
designed to foster federal agencies' adoption of
cloud computing, support the private sector,
improve the information available to decision
makers and facilitate the continued development
of the cloud computing model. NIST plans to
issue the final U.S. Government Cloud Computing
Roadmap as a three-volume work. The first two
volumes were posted for public comment on 1 Nov.
2011. The draft publication defines
high-priority requirements for standards,
official guidance and technology developments
that need to be met in order for agencies to
accelerate their migration of existing IT
systems to the cloud computing model.

2. Romine To
Head NIST Information Technology Laboratory
On 21 Nov., Charles (Chuck) H.
Romine became director of the Information
Technology Laboratory (ITL) of the National
Institute of Standards and Technology (NIST).
Romine joined NIST in 2009, and most recently
served as the acting associate director for NIST
laboratory programs. Before joining NIST, Romine
spent five years in the White House Office of
Science and Technology Policy as a senior policy
analyst on information technology. Romine
received a Ph.D. in applied mathematics and a
B.A. in mathematics, both from the University of
Virginia. He began his career in the Department
of Energy, spending 15 years at Oak Ridge
National Laboratory, conducting research on
advanced algorithms for supercomputers and four
years in DOE’s Office of Science as program
manager for the Office of Advanced Scientific
Computing Research.

Researchers Watch Next-Gen Memory Bit Switch in
Real Time
For the first time, engineering
researchers have been able to watch in real time
the nanoscale process of a ferroelectric memory
bit switching between the 0 and 1 states.
Ferroelectric materials have the potential to
replace current memory designs, offering greater
storage capacity than magnetic hard drives and
faster write speed and longer lifetimes than
flash memory. Replacing dynamic random access
memory — the short-term memory that allows your
computer to operate — with ferroelectric memory
can significantly decrease energy usage in
computers. Ferroelectric memory doesn't require
power to retain data. According to principal
investigator Xiaoqing Pan, director of the
University of Michigan’s Electron Microbeam
Analysis Laboratory, "by following ferroelectric
switching at this scale in real time, we've been
able to observe new and unexpected phenomena.
This work will help us understand how these
systems work so one can make better memory
devices that are faster, smaller and more
reliable."

4.
Researchers Demonstrate A Smarter Way To Make
Ultraviolet Light Beams
Existing coherent ultraviolet
light sources are power hungry, bulky and
expensive. University of Michigan researchers
have found a better way to build compact
ultraviolet sources with low power consumption
that could improve information storage,
microscopy and chemical analysis. Led by Mona
Jarrahi and Tal Carmon, assistant professors in
the Department of Electrical Engineering and
Computer Science, the researchers optimized a
type of optical resonator to take an infrared
signal from relatively cheap
telecommunication-compatible lasers and, using a
low-power, nonlinear process, boost it to a
higher-energy ultraviolet beam. Their optical
resonator is a millimeter-scale disk with a
precisely engineered shape and smooth surface
polishing to encourage the input beam to gain
power as it circulates inside the resonator.
Ultraviolet light sources have applications in
chemical detection, crisper medical imaging and
finer lithography for more sophisticated
integrated circuits and greater computer memory
capacity.

5. New
Material Enhances Application of Piezoelectrics
to MEMS
A team of university
researchers, aided by the National Institute of
Standards and Technology (NIST), have succeeded
in integrating a new, highly efficient
piezoelectric material, dubbed PMN-PT, into a
silicon microelectromechanical system (MEMS),
delivering two to four times more movement with
stronger force — while using only 3 volts — than
most rival materials studied to date. This
development could lead to significant advances
in sensing, imaging and energy harvesting.
Although conventional piezoelectric materials
work fairly well for many applications,
researchers have long sought to find or invent
new ones that expand more and more forcefully
and produce stronger electrical signals. More
reactive materials would make for better sensors
and could enable new technologies such as
"energy harvesting," which would transform the
energy of walking and other mechanical motions
into electrical power.

6. New
Magnetic-Field-Sensitive Alloy Could Find Use in
Novel Micromechanical Devices
A multi-institution team of
researchers has combined modern materials
research and an age-old metallurgy technique to
produce an alloy that could be the basis for a
new class of sensors and micromechanical devices
controlled by magnetism. The alloy, a
combination of cobalt and iron, is notable,
among other things, for not using rare-earth
elements to achieve its properties. The alloy
exhibits a phenomenon called "giant
magnetostriction," an amplified change in
dimensions when placed in a sufficiently strong
magnetic field. The effect is analogous to the
more familiar piezoelectric effect that causes
certain materials, like quartz, to compress
under an electric field. They can be used in a
variety of ways, including as sensitive magnetic
field detectors and tiny actuators for
micromechanical devices. The latter is
particularly interesting to engineers because,
unlike piezoelectrics, magnetostrictive elements
require no wires and can be controlled by an
external magnetic field source.

http://www.nist.gov/mml/metallurgy/magnetism-112211.cfm
7. Electron
Beams Can Be Used as Nanoscale “Tweezers”
A recent paper by researchers
from the National Institute of Standards and
Technology (NIST) and the University of Virginia
(UVA) demonstrates that the beams produced by
modern electron microscopes can be used not just
to look at nanoscale objects, but to move them
around, position them and perhaps even assemble
them. Essentially, they say, the tool is an
electron version of the laser “optical tweezers”
that have become a standard tool in biology,
physics and chemistry for manipulating tiny
particles. Except that electron beams could
offer a thousand-fold improvement in sensitivity
and resolution. According to NIST metallurgist
Vladimir Oleshko “electron probes can be very
fine, three orders of magnitude smaller than
photon beams — close to the size of single
atoms. We could manipulate very small
quantities, even single atoms, in a very precise
way.”

8. Graphene
Interconnects Enhanced for Nanoelectronic
Applications
A new study at Rensselaer
Polytechnic Institute could hasten the downfall
of copper as the ubiquitous metal in smart
phones, tablet computers, and nearly all
electronics. This is good news for technophiles
who are seeking smaller, faster devices. As new
generations of computer chips continue to shrink
in size, so do the copper pathways that
transport electricity and information around the
labyrinth of transistors and components. When
these pathways — called interconnects — grow
smaller, they become less efficient, consume
more power, and are more prone to permanent
failure. To overcome this hurdle, industry and
academia are vigorously researching new
candidates to succeed traditional copper as the
material of choice for interconnects on computer
chips. One promising candidate is graphene, an
atom-thick sheet of carbon atoms arranged like a
nanoscale chicken-wire fence. Led by Rensselaer
Professor Saroj Nayak, a team of researchers
discovered they could enhance the ability of
graphene to transmit electricity by stacking
several thin graphene ribbons on top of one
another.

9. Swarm of
Tiny, Collaborative Robots Now Available to
Researchers
Computer scientists and
engineers at Harvard University have developed
and licensed technology that will make it easy
to test collective algorithms on hundreds, or
even thousands, of tiny robots. Called Kilobots,
the quarter-sized bug-like devices scuttle
around on three toothpick-like legs, interacting
and coordinating their own behavior as a team. A
June 2011 Harvard Technical Report demonstrated
a collective of 25 machines implementing
swarming behaviors such as foraging, formation
control, and synchronization. Once up and
running, the machines are fully autonomous,
meaning there is no need for a human to control
their actions.

10. Software
Predicts Physical Behavior of Newly Designed
Robots
Researchers from three
universities are collaborating to develop a new
generation of design software that can
accurately predict the physical behavior of
robots prior to prototyping. "One of our goals
is to find a way to do virtual testing so that
key flaws can be found on a computer before a
prototype is ever built," said Walid Taha,
adjunct professor of computer science at Rice
University and professor of computer science at
Halmstad University in Sweden. Taha is principal
investigator on a new research grant from the
National Science Foundation (NSF) that brings
together researchers from Rice, Halmstad and
Texas A&M University.

11. DARPA
Announces Crowd-Sources Formal Verification
Program For Software
Formal program verification is a
proven method for reducing defects in software
and proving that software has specified
properties, but formal verification does not
currently scale to the size of software found in
modern weapon systems. Moreover, formal
verification is currently performed by highly
specialized researchers with deep knowledge of
software technology and mathematical
theorem-proving techniques. Because of these
constraints and the resulting high costs, formal
verification is not widely practiced, an issue
of particular concern for the Department of
Defense.
DARPA’s Crowd Sourced Formal
Verification (CSFV) program seeks to make formal
verification of software more cost effective by
enabling non-specialists to participate
productively in the formal verification process.
CSFV’s approach is to transform formal
verification into a game that is intuitively
understandable and fun to play. The envisioned
CSFV system would create a specific game
instance based on the particular software
implementation and software property to be
verified. Playing, and completing, the CSFV game
enables formal verification tools to complete a
corresponding formal software verification
proof.

University-Industry Research Collaboration to
Focus on More Energy Efficient Data Center
Operation
Three of the nation's leading
universities have joined with 15 US companies to
launch a first-of-its-kind collaborative
research center whose holistic approach to
energy efficiency development could mean savings
of millions of dollars and a much 'greener'
electronics industry. Headed up by researchers
at Binghamton University and its partners,
Villanova University and the University of Texas
at Arlington, the newly designated National
Science Foundation (NSF) Industry/University
Cooperative Research Center in Energy-Efficient
Electronic Systems (I/UCRC E3S) will link the
fields of information technology,
telecommunications, electronic systems and
cooling equipment to solve issues of
energy-efficiency in data center operation.

13. DOE
Seeks to Reduce Non-Hardware Costs of Solar
Energy Systems
As part of the U.S. Department
of Energy’s SunShot Initiative, Energy Secretary
Steven Chu announced on 15 Nov. up to $7 million
in DoE funding to reduce the non-hardware costs
of residential and commercial solar energy
installations. Made available through the
SunShot Incubator Program, this funding will
support the development of tools and approaches
that reduce non-hardware, or “soft” costs, such
as installation, permitting, interconnection,
and inspection. These expenses can amount to up
to half of the cost of residential systems. The
Incubator will make the process of buying,
installing, and maintaining solar energy systems
faster, easier, and less expensive.

14. National
STEM Video Competition Open for Students and
Educators
In mid-November,the 2012
National STEM Video Game Challenge was
officially launched, aiming to motivate interest
in science, technology, engineering, and math
(STEM) learning by tapping into students’
natural passion for playing and making video
games. This competition is the culmination and
continuation of a two-year effort among the
Entertainment Software Association (ESA), the
White House, the Department of Education’s
Digital Promise Initiative and other
public/private partners and co-sponsors. The
annual competition is accepting submissions of
original video game concepts and designs in four
different categories: the Middle School
Category, High School Category, Collegiate
Category, and Educator Category. This year,
there are also new sub-categories available to
entering designers: the PBS KIDS stream and the
Sesame Street stream.

15. Research
Project Seeks to Boost Computer Science
Knowledge Through Gaming
North Carolina State University
researchers are launching a project to develop a
video game that will help improve computer
science knowledge in middle school students and
contribute to a better educated workforce in the
future. The game, which is being developed under
a one million dollar grant from the National
Science Foundation, could be used nationally if
it proves successful.

16. New
Partnership Seeks to Enhance Cyber Security
Education
On 8 Nov., the National
Institute of Standards and Technology (NIST),
the Department of Education and a new
organization, and the National Cybersecurity
Education Council (NCEC), announced a strategic
public-private partnership to promote formal
cybersecurity education.
The plan, outlined in a recent
Memorandum of Understanding (MOU), is designed
to help the National Initiative for
Cybersecurity Education (NICE) meet one of its
top priorities, to “broaden the pool of skilled
workers capable of supporting a cyber-secure
nation.”

17. Improved
Tool for Hardening Software Against Cyber Attack
Computer scientists at the
National Institute of Standards and Technology (NIST)
have dramatically enlarged a database designed
to improve applications that help programmers
find weaknesses in software. This database, the
SAMATE Reference Dataset (SRD), version 4.0, is
a freely available online tool aimed at helping
programmers fortify their creations against
hackers.

18.
Researchers Find Some Smartphone Models More
Vulnerable to Attack
New research from North Carolina
State University shows that some smartphones
specifically designed to support the Android
mobile platform have incorporated additional
features that can be used by hackers to bypass
Android’s security features, making them more
vulnerable to attack. Android has the largest
share of the smartphone market in the United
States.
“Some of these pre-loaded
applications, or features, are designed to make
the smartphones more user-friendly, such as
features that notify you of missed calls or text
messages,” says Dr. Xuxian Jiang, an assistant
professor of computer science at NC State and
co-author of a paper describing the research.
“The problem is that these pre-loaded apps are
built on top of the existing Android
architecture in such a way as to create
potential ‘backdoors’ that can be used to give
third-parties direct access to personal
information or other phone features.”

19.
Nanowires Could Be Solution For High Performance
Solar Cells
Tiny wires could help engineers
realize high-performance solar cells and other
electronics, according to University of Illinois
researchers. The researchers have developed a
technique to integrate compound semiconductor
nanowires on silicon wafers, overcoming the
challenge of lattice mismatch and reducing
defects in devices.

20. New
Technology Improves Capacity and Charge Rate of
Rechargeable Batteries
Northwestern University
engineers have created an electrode for
lithium-ion batteries that allows the
rechargeable batteries to hold a charge up to 10
times greater than current technology. The
batteries also can charge 10 times faster than
current batteries. The researchers combined two
chemical engineering approaches to address two
major battery limitations — energy capacity and
charge rate — in one fell swoop. The technology
could pave the way for better batteries for
cellphones, iPods and electric cars.

http://www.eurekalert.org/pub_releases/2011-11/nu-bb111411.php
21. New
Report Urges Utility Submetering to Improve
Building Efficiency
A new interagency report
recommends systematic consideration of new
metering technologies, called submetering, that
can yield up-to-date, finely grained snapshots
of energy and water usage in commercial and
residential buildings to guide efficiency
improvements and capture the advantages of a
modernized electric power grid. Commercial and
residential buildings consume vast amounts of
energy, water, and material resources. In fact,
U.S. buildings account for more than 40 percent
of total U.S. energy consumption, including 72
percent of electricity use. If current trends
continue, buildings worldwide will be the
largest consumer of global energy by 2025. By
2050, buildings are likely to use as much energy
as the transportation and industrial sectors
combined.

22. DARPA
Aims to Launch Small Satellites Faster, Cheaper
On 11 Nov., DARPA announced its
new Airborne Launch Assist Space Access (ALASA)
program, which seeks to reduce cost, time and
weather constraints for launching small
satellites from an aircraft. The programs goal
is to put 100-pound satellites into orbit for
one-third the current cost.
