Activity from phony Twitter accounts established by the Russian Internet Research Agency (IRA) between 2015 and 2017 may have contributed to politicizing Americans' position on the nature and efficacy of vaccines, a health care topic which has not historically fallen along party lines, according to new research published in the American Journal of Public Health.
The temptation for businesses to use artificial intelligence and other technology to improve performance, drive down labor costs, and better the bottom line is understandable. But before pursuing automation that could put the jobs of human employees at risk, it is important that business owners take careful stock of their operations.
During the 2016 election cycle, politically polarizing tweets by Russian trolls about vaccination included pro- and anti-vaccination messages targeted at people with specific political inclinations through a nine different fake persona types, according to a new study. Now, as the nation deals with the coronavirus pandemic, the researchers raise concerns that such polarization potentially affects crisis communications and creates tensions, mistrust, and a lack of intention to comply with government health directives.
Engineers at Caltech have shown that atoms in optical cavities could be foundational to the creation of a quantum internet.
Researchers have demonstrated a new model of how competing pieces of information spread in online social networks and the Internet of Things (IoT). The findings could be used to disseminate accurate information more quickly, displacing false information about anything from computer security to public health.
Researchers at EPFL have developed a nanodevice, described today in Nature, that operates more than 10 times faster than today's fastest transistors. It enables the generation of high-power terahertz waves. These waves, which are notoriously difficult to produce, are useful in a rich variety of applications ranging from imaging and sensing to high-speed wireless communications. The high-power picosecond operation of these device also hold immense promise to some advanced medical treatment techniques such as cancer therapy.
A 30% increase in buyer attention increases the likelihood of a contract award by seven times.
The field of 'brain-mimicking' neuromorphic electronics shows great potential for basic research and commercial applications, and researchers in Germany and Switzerland recently explored the possibility of reproducing the physics of real neural circuits by using the physics of silicon. In Applied Physics Letters, they present their work to understand neural processing systems, as well as a recipe to reproduce these computing principles in mixed signal analog/digital electronics and novel materials.
Researchers at Los Alamos National Laboratory are reinventing the mirror, at least for microwaves, potentially replacing the familiar 3-D dishes and microwave horns we see on rooftops and cell towers with flat panels that are compact, versatile, and better adapted for modern communication technologies.
Harvard and MIT researchers have found a way to correct for signal loss with a prototype quantum node that can catch, store and entangle bits of quantum information. The research is the missing link towards a practical quantum internet and a major step forward in the development of long-distance quantum networks.
