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.
Physicists have come up with a mathematical explanation for moths' remarkable ability to find mates in the dark hundreds of meters away. The researchers said the results could also be applied widely in agriculture or robotics. By controlling the behaviors of insects exposed to pheromones, they said, researchers could limit the ability of invasive or disease-carrying pests to mate.
Researchers have developed new software that estimates how much farther electric vehicles can drive before needing to recharge. The new technique requires drivers to plug in their destination and automatically pulls in data on a host of variables to predict energy use for the vehicle.
A new study demonstrates that quantum holograms could be a candidate for becoming quantum information memory. Scientists have developed a theoretical model of quantum memory for light, adapting the concept of a hologram to a quantum system.
An increasing number of assistance systems are being designed to facilitate driving. Things are heading towards automated driving. What role does the person behind the steering wheel play? Scientists have now developed “pieDrive”, an interactive operating concept for vehicles of the future.
Researchers have advanced the field of affective computing -- the creation of computer systems that recognize, express and process human emotions -- by proposing a new way to recognize emotion in text. Their development has significant potential for business applications.
Fewer cords, smaller antennas and quicker video transmission. This may be the result of a new type of microwave circuit. The research team behind the circuits currently holds an attention-grabbing record.
New medications created by pharmaceutical companies have helped millions of Americans alleviate pain and suffering from their medical conditions. However, the drug creation process often misses many side effects that kill at least 100,000 patients a year. Now researchers have discovered a high-tech method of using supercomputers to identify proteins that cause medications to have certain adverse drug reactions (ADR) or side effects.
