Smartphones have seen wide adoption among Americans in recent years because of their ease of use and adaptability. With that in mind, researchers examined how smartphone use affected weight loss goals and determined that smartphones may offer users an advantage over traditional methods when tracking diet data.
A flexible display incorporating graphene in its pixels’ electronics has been successfully demonstrated, the first time graphene has been used in a transistor-based flexible device.
Scientists have uncovered a new method to detect Majorana particles, a key element for a next-generation quantum computing platform. Quantum computing relies on the laws of quantum mechanics to process vast amounts of information and calculations simultaneously, with far more power than current computers. However, development of quantum computers has been limited as researchers have struggled to find a reliable way to increase the power of these systems, a power measured in Q-Bits.
Geography researchers have developed a large-scale mapping technique to track a variety of demographic data across the United States, including researching populations based on gender, race and economic diversity. Details on the technique behind the new, high resolution, grid-based map of U.S. demographics are now available online.
An evolutionary analysis of public health data during a major disease outbreak, such as bird flu, E. coli contamination of food or the current Ebola outbreak could help the emergency services plan their response and contain the disease more effectively.
Many people are unaware that the US Food and Drug Administration's mandated nutrition labels are based on a 2,000-calorie-a-day diet, but a simple weekly text message reminder can greatly improve that awareness, according to a new study.
If you want to learn more about the people in urban communities, save a stamp on mailing a survey. Just text them. A new pilot study among low-income African-Americans in Detroit suggests that there is a clear preference on how residents choose to communicate -- whether it's by researchers asking questions for a health study or community advocates gauging resource needs. They want you to talk to them through their phones.
Scientists have sent a pulse of bright light in a particularly sensitive quantum state through 1.6 kilometers of air. This quantum state, which they call squeezed, was maintained, which is something many physicists thought to be impossible. Eavesdropping on a message protected by quantum cryptography cannot be done without being noticed.
A smart headlight enables drivers to take full advantage of their high beams without fear of blinding oncoming drivers or suffering from the glare that can occur when driving in snow or rain at night.
Researchers have developed artificial intelligence software that is significantly better than any previous technology at predicting what goal a player is trying to achieve in a video game. The advance holds promise for helping game developers design new ways of improving the gameplay experience for players.
Pioneering research into making ultra-high definition TV (UHDTV) available to the masses will be showcased at the world’s biggest international broadcasting event this week.
Scientists have married two unconventional forms of carbon -- one shaped like a soccer ball, the other a tiny diamond -- to make a molecule that conducts electricity in only one direction. This tiny electronic component, known as a rectifier, could play a key role in shrinking chip components down to the size of molecules to enable faster, more powerful devices.
Researchers have developed a tool to help security analysts protect markets and users from malware. This system allows a large number of apps to be analyzed in order to determine the malware's origins and family.
Medical researchers have designed a remote medical care system that supports the rehabilitation of people with spasticity, an alteration of the nervous system related to increased tone muscle making motor skills difficult or impossible for those affected.
Sandwiching layers of graphene with white graphene could produce designer materials capable of creating high-frequency electronic devices, scientists have found.
A new software platform supports the complete work process of finding new pharmaceutical agents in cancer research and tissue analysis. The software was developed specifically for high content analysis of live cell imaging data that monitor and record the complete life cycle of cells. The particular challenge for image analysis here is to detect the different phases of cell modification and cell division, and to record their temporal relationship.
Social networking programs designed to help people lose weight could play a role in the global fight against obesity, according to research. Obesity is an increasing issue in developed and developing countries, contributing to other diseases such as diabetes, cardiovascular disease, cancer and mental health problems and resulting in rising costs for health services.
The U.S. government is doing a better job of communicating on Twitter with people in sensitive areas like the Middle East and North Africa without the participation of media organizations, according to a study.
Researchers have demonstrated an atomically thin, ultrasensitive and scalable molybdenum disulfide field-effect transistor based biosensors and establish their potential for single-molecule detection.
For decades, medical researchers have sought new methods to diagnose how different types of cells and systems in the body are functioning. Now scientists have adapted an emerging biomedical technique to study the vast body of the ocean.
