Computer-Aided Nodule Assessment and Risk Yield, is a novel software tool that can automatically quantitate adenocarcinoma pulmonary nodule characteristics from non-invasive high resolution computed tomography images and stratify non-small cell lung cancer patients into risk groups that have significantly different disease-free survival outcome.
Several new components for biological circuits have been developed by researchers. These components are key building blocks for constructing precisely functioning and programmable bio-computers. "The ability to combine biological components at will in a modular, plug-and-play fashion means that we now approach the stage when the concept of programming as we know it from software engineering can be applied to biological computers. Bio-engineers will literally be able to program in future."
Simulating the behavior of a single particle can be quite a challenging task in physics; after all, it is microscopic and we usually cannot watch in real time. It becomes even more complicated when you realize that the particle has to follow the laws of quantum physics, which allow it be in two or more places at the same time through a phenomenon called superposition. Understanding how a quantum particle behaves is necessary to enhance our fundamental understanding of the laws of physics.
There is a general correlation between unemployment and suicide among men. But the weaker the unemployment protection in the country, the stronger the connection. These findings are reported in a comparative study covering thirty countries, focusing the impact of the Great Recession on unemployment and suicide rates.
A new technique for heat-assisted magnetic recording media promises improved writeability for next-generation hard drives.
An online model for follow-up care of atopic dermatitis, better known as eczema, that gave patients direct access to dermatologists resulted in equivalent clinical improvement compared to patients who received traditional in-person care, a study finds.
As would be expected during a time of consumer deleveraging, households applied more than 70 percent of their mortgage savings to reducing outstanding credit card debts. Not only did the lower payments reduce mortgage defaults but credit card delinquencies fell. 'These choices had significant impact on foreclosures, house prices and employment in regions that were more exposed to interest rate declines,' the researchers concluded.
Unmanned aerial vehicles, or drones, can collect detailed information in real time at relatively low cost for ecological research. In a new article, experts demonstrate that drones can be used to understand how environmental factors influence the spread of infectious diseases.
Complex biochemical signals that coordinate fast and slow changes in neuronal networks keep the brain in balance during learning, according to an international team of scientists. Neuronal networks form a learning machine that allows the brain to extract and store new information from its surroundings via the senses. Researchers have long puzzled over how the brain achieves sensitivity and stability to unexpected new experiences during learning -- two seemingly contradictory requirements.
Major leaks from oil and gas pipelines have led to home evacuations, explosions, millions of dollars in lawsuit payouts and valuable natural resources escaping into the air, ground and water. Scientists say they have now developed a new software-based method that finds leaks even when they're small, which could help prevent serious incidents -- and save money for customers and industry.
Children with autism spectrum disorder were more likely to have been exposed to higher levels of certain air toxics during their mothers' pregnancies and the first two years of life compared to children without the condition, according to the preliminary findings of an investigation of American children.
Scientists see good times approaching for astrophysicists after hatching a new observational strategy to distill detailed information from galaxies at the edge of the Universe. Using two world-class supercomputers, the researchers were able to demonstrate the effectiveness of their approach by simulating the formation of a massive galaxy at the dawn of cosmic time. The ALMA radio telescope – which stands at an elevation of 5,000 meters in the Atacama Desert of Chile, one of the driest places on earth – was then used to forge observations of the galaxy, showing how their method improves upon previous efforts.
The question if an individual will suffer from relapsing major depressive disorder is not determined by accident. Neuroscientists have chosen a new research approach, using computer-based models to study the disease. They show that chronic depression is triggered due to an unfortunate combination of internal and external factors.
The supply chain is ground zero for several recent cyber breaches. Hackers, for example, prey on vendors that have remote access to a larger company's global information technology systems, software and networks. A counter-measure, via a user-ready online portal, has now been developed by researchers.
Personalized nutrition based on an individual's genotype - nutrigenomics - could have a major impact on reducing lifestyle-linked diseases such as obesity, heart disease and Type II diabetes, experts say. However, a study of more than 9,000 volunteers reveals that strict regulations need to be put in place before nutrigenomics becomes publicly acceptable due to people's fears around personal data protection.
Technology to help a blind student see math clearly and pursue a degree has been uncovered by researchers. Despite losing her vision three years ago due to complications from the flu, one study entered university last fall with the specific goal of pursuing a dual degree in mathematics and business. Technology is helping her make this a reality.
Scientific inquiry is a hit and miss proposition, subject to constant checking and rechecking. Recently, a new class of materials was discovered called topological insulators—nonmetallic materials with a metallic surface capable of conducting electrons. The effect, based on relativity theory, exists only in special materials -— those with heavy elements —- and has the potential to revolutionize electronics.
Playing violent video games in 3-D makes everything seem more real -- and that may have troubling consequences for players, a new study reveals. Researchers found that people who played violent video games in 3-D showed more evidence of anger afterward than did people who played using traditional 2-D systems -- even those with large screens.
Less-numerate investors are more susceptible to style and presentation effects in corporate social responsibility reports, according to new research.
Social networks can be a viable source for photo-vouchered biodiversity records, especially those that clarify which species exist in what places within developing nations, one expert suggests.
