Computer scientists have shown that an important class of artificial intelligence (AI) algorithms could be implemented using chemical reactions. In the long term, they say, such theoretical developments could open the door for "smart drugs" that can automatically detect, diagnose, and treat a variety of diseases using a cocktail of chemicals that can perform AI-type reasoning.
By taking advantage of the unique electronic properties of the material known as graphene, researchers now believe they're on track to connect networks of nanomachines powered by small amounts of scavenged energy.
New research shows that behavior can be predicted and understood in thin films made of materials called relaxors, which can be used in electronic devices.
Maybe it happens tomorrow. Maybe in a billion years. Physicists have long predicted that the universe may one day collapse, and that everything in it will be compressed to a small hard ball. New calculations now confirm this prediction -- and they also conclude that the risk of a collapse is even greater than previously thought.
Scientists are working to develop interaction between themselves and mobiles/ iPads - which does not require touching the display. They have been able to scroll through pages for some time. Now they are working on selecting and moving objects, or saying stop by raising a hand.
Researchers have successfully developed an innovative one-step method to grow and transfer high-quality graphene on silicon and other stiff substrates, opening up opportunities for graphene to be used in high-value applications that are currently not technologically feasible.
A pilot program offering telehealth technology to pediatric obesity patients found that a great majority of pediatric patients were satisfied with their telehealth appointment.
There may be a better way to analyze the genetic causes of cutaneous melanoma according to a study published. A statistical analysis using the natural and orthogonal interaction model showed increased power over existing approaches for detecting genetic effects and interactions when applied to the genome-wide melanoma dataset.
Imagine playing a video game like Call of Duty or Battlefield and having the ability to lead your virtual army unit while moving freely throughout your house. Gaming could become this realistic, thanks to new technology that allows for highly accurate, 3-D motion tracking. The new system, dubbed "WiTrack," uses radio signals to track a person through walls and obstructions, pinpointing her 3-D location to within 10 to 20 centimeters -- about the width of an adult hand.
A long-standing difficulty with supercomputer simulations of the evolution of galaxies has been getting consistent results among different codes (programs) and with actual observations, so simulated galaxies look like real galaxies. But reproducibility is one of the most elementary principles in scientific methods. An ambitious new multiyear project AGORA aims to understand and resolve such inconsistencies.
The stronger a community's social ties and the longer most people stay within the community, the more likely it is that bystanders will step forward to punish a neighbor for perceived wrongdoing. A psychologist teamed with campus computer scientists, using evolutionary game theory to predict the emergence of this complex human behavior.
When a person is arrested, part of the procedure is to have a ‘booking photo’ taken of the accused. In the US, these are stored on arresting agency websites and are publicly available. There has been a rise in the practice of ‘scraping’ mug shots and posting them live on websites where anyone can chance upon a photo of a loved one or friend who may have inadvertently committed a minor offense. Thousands of individuals have been affected by this phenomenon in terms of employability and reputation, and are having to pay specialist companies to remove the photos from public view.
85 out of every 100 people in Switzerland have access to the internet. Internet usage is on the rise, with even 70 percent of senior citizens going online. However, the concerns about using the internet are still substantial with regard to companies monitoring data. In general, study results show that young people are less worried about privacy, and in general, women are more concerned about protecting their privacy than men.
Researchers have built nanoscale electromechanical switches and logic gates that operate more energy-efficiently than those now used by the billions in computers, tablets and smart phones. The switches are fast and light and have proved durable and heat tolerant, with no current leakage.
A friend posts a picture on Facebook that shows you picking food out of your teeth. Awkward! Such Facebook faux pas are common. But depending on who you are and to whom you allow access to your Facebook page, such embarrassments can cause greater anguish, according to a new study.
A massive ejection of material from the sun initially traveling at over 7 million miles per hour that narrowly missed Earth last year is an event solar scientists hope will open the eyes of policymakers regarding the impacts and mitigation of severe space weather.
Coronary heart disease accounts for 18 percent of deaths in the United States every year. The disease results from a blockage of one or more arteries that supply blood to the heart muscle due to an inflammatory condition called artherosclerosis, leading to progressive buildup of fatty plaque near the surface of the arterial wall. A paper published proposes a mathematical model to improve currently-employed treatments of coronary heart disease.
Scientists may be one step closer to tapping into the full potential of solar cells. The team found a way to create large sheets of nanotextured, silicon micro-cell arrays that hold the promise of making solar cells lightweight, more efficient, bendable and easy to mass produce.
Scientists find plasmons at the root of a terahertz peak seen in carbon nanotubes, but only in certain types. The discovery opens up the possibility of using nanotubes in terahertz-based optoelectronics.
Millions of previously hidden US stock trades will be revealed for the first time on Monday December 9 thanks to research from a team of academics.
