Adding defects to superconducting wire creates unprecedented performance

August 19, 2013

BZO-doped films

The ability to control nanoscale imperfections in superconducting wires results in materials with unparalleled and customized performance, according to a new study from the Department of Energy’s Oak Ridge National Laboratory.

Applications for superconducting wires, which carry electricity without resistance when cooled to a critical temperature, include underground transmission cables, transformers and large-scale motors and generators. But these applications require wires to operate under different temperature and… read more

Adding Human Intelligence to Software

October 18, 2010

Computer scientists at MIT have developed a toolkit that allows new software applications to combine and coordinate the efforts of Amazon’s Mechanical Turk workers. Called TurKit, the tool lets software engineers write algorithms to coordinate online workers using the Javascript programming language, and create powerful applications that have human intelligence built in.

Adding Speed to Silicon

July 24, 2007

AmberWave Systems has developed a new method for growing germanium and other semiconductors on silicon so they don’t crack.

It could lead to faster, smaller electronics. Additionally, combining the different types of semiconductors could lead to cheaper lasers and other photonic devices.

The dimensions of transistors are shrinking, and silicon, as it’s used today to make these transistors, will not be able to scale down and maintain the… read more

Adobe Blurs Line Between PC and Web

February 25, 2008

On Monday, Adobe will release AIR, a software development system that will power potentially tens of thousands of applications that merge the Internet and the PC, as well as blur the distinctions between PCs and new computing devices like smartphones.

Adobe Carousel Mac OS and iOS app takes photo editing/sharing to the cloud

September 9, 2011

Adobe Systems has announced Adobe Carousel for iPad, iPhone, iPod touch and Mac OS, using the cloud to provide a simple way to view, browse, adjust and share photos without worrying about manual syncing or storage.

Adobe Carousel uses the powerful photo-processing technology used in Adobe Photoshop Lightroom, providing quality photo-editing results on multiple devices. Edits, deletions or additions to the library made on one… read more

Adobe offers early peek at Apollo

March 19, 2007

Apollo, planned for the second half of this year, is designed to bridge the world of Web applications and desktop computers.

The release of the software is highly anticipated among people who develop so-called rich Internet applications, meaning Web applications that have some of the interactivity of traditional desktop applications.

Adroit Droids

October 29, 2004

Advances in sensors, software, and computer architecture are beginning to give robots a sense of their “bodies” and of what sorts of actions are safe and useful in their environments.

One of the world’s most advanced robots passed an important test at NASA’s Johnson Space Center in Houston: it learned to use tools to tighten bolts on a wheel. Rather than having to be separately programmed for each of… read more

Adult brain cells made to multiply and regenerate

August 21, 2006

Adult human brain cells can generate new tissue when implanted into in the brains of mice, new research reveals. The findings could pave the way to new therapies for a host of neurodegenerative diseases, including Alzheimer’s.

Adult Cells, Reprogrammed To Embryonic Stem Cell Like State, Treat Sickle-cell Anemia In Mice

December 10, 2007

Whitehead Institute for Biomedical Research scientists have successfully treated mice with a human sickle-cell anemia disease trait in a process that begins by directly reprogramming their own cells to an embryonic-stem-cell-like state, without the use of eggs.

This is the first proof-of-principle of therapeutic application in mice of directly reprogrammed “induced pluripotent stem” (IPS) cells, which recently have been derived in mice as well as humans.

Adult heart derived stem cells develop into heart muscle

April 24, 2008

University Medical Center Utrecht and Hubrecht Institute researchers have succeeded in taking stem cells from adult human hearts and growing them into large numbers of new heart muscle cells.

The stem cells were derived from material left over from open-heart operations, and grew into fully developed heart muscle cells that contract rhythmically, respond to electrical activity, and react to adrenaline.

The method results in identical cells that could… read more

Adult stem cell transplants fail in 2 studies

March 23, 2004

Two failed attempts to transplant adult stem cells into the hearts of laboratory mice are casting doubt on the value and safety of clinical trials testing a similar approach to repair the hearts of humans.

Adult stem cells can at least make blood

January 26, 2007

Transplanted “multipotent” adult progenitor cells (MAPCs) from bone marrow were able to form all blood cell types in mouse experiments.

Adult stem cells help heal broken bones

June 17, 2008

University of North Carolina at Chapel Hill researchers have shown that transplanting adult stem cells to broken bones can help to heal fractures in mice.

The researchers took adult stem cells from the bone marrow of mice that had fractured tibia (the long bone of the leg). The cells were engineered to make insulin-like growth factor 1 (IGF-1), a potent bone regenerator. When the cells were injected into the… read more

Adult stem cells that do not age

October 4, 2010

Biomedical researchers at the University at Buffalo have engineered adult stem cells that scientists can grow continuously in culture, a discovery that could speed development of cost-effective treatments for diseases including heart disease, diabetes, immune disorders and neurodegenerative diseases.

UB scientists created the new “MSC Universal”cell lines by genetically altering mesenchymal stem cells, which are found in bone marrow and can differentiate into cell types including bone, cartilage, muscle,… read more

Advance in dip-pen nanolithography promises miniaturized gene chips, nanoscale electronics

September 27, 2006

Northwestern University researchers have developed a 55,000-pen, two-dimensional array that allows them to simultaneously create 55,000 identical patterns drawn with tiny dots of molecular ink on substrates of gold or glass. Each structure is only a single molecule tall.

The parallel process paves the way for making DPN competitive with other optical and stamping lithographic methods used for patterning large areas on metal and semiconductor substrates, including silicon wafers.… read more
