Using brain data, eye-tracking data and field-study data, researchers have confirmed something about our interaction with security warnings on computers and phones: the more we see them, the more we tune them out. But they've also found that slight changes to the appearance of warnings help users pay attention to and adhere to warnings 20 percent more of the time.
At the International Conference on Robotics and Automation, researchers from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) will present a new lane-change algorithm that splits the difference. It allows for more aggressive lane changes than the simple models do but relies only on immediate information about other vehicles' directions and velocities to make decisions.
Physicists at Saarland University in Saarbrücken, Germany, have succeeded in entangling a single atom with a single photon in the telecom wavelength range. This constitutes a basic building block for transmission of quantum information over long distance with low loss. The results have raised great attention in the quantum technology community; now they are published in Nature Communications.
Recent research at the University of Illinois demonstrated that, although most wing shapes used today create turbulent wake vortices, wing geometrics can be designed to reduce or eliminate wingtip vortices almost entirely. In the study, the vortex and wake characteristics were computed for three classic wing designs: the elliptic wing, and wing designs developed in classic studies by R.T. Jones and Ludwig Prandt.
The world's cutting-edge particle accelerators are pushing the extremes in high-brightness beams and ultrashort pulses to explore matter in new ways. To optimize their performance -- and to prepare for next-generation facilities that will push these extremes further -- scientists have devised a new tool that can measure how bright these beams are, even for pulses that last only quadrillionths or even quintillionths of a second.
A joint research team from Tokyo Tech and North Carolina State University has clarified the fundamental principles for achieving the synchronization of power generator groups in power networks, which is essential for the stable supply of electric power. Based on this principle, the team developed a method for constructing an aggregated model of a power network that can efficiently analyze and control the behavior of generator groups (including rotor phase angles and connection point voltages) with complex connection to a power grid.
Parents don't need to fear their children playing with iPads and other devices, researchers say. Mindful play with an adult, combined with thoughtful design features, can prove beneficial to young developing minds. New research shows that thoughtfully designed content that intentionally supports parent-child interactions facilitated the same kind of play and development as analog toys.
Scientific software resources are an integral part of the nation's cyberinfrastructure. The Texas Advanced Computing Center (TACC) is among the national leaders in developing software for scientific computing. Researchers from TACC will present emerging tools at the NSF SI2 Principle Investigators Workshop from April 30-May 2 in Washington, D.C.
Researchers have created a new material that represents a key step toward the next generation of supercomputers.
While we embrace the way the Internet of Things already is making our lives more streamlined and convenient, the cybersecurity risk posed by millions of wirelessly connected gadgets, devices and appliances remains a huge concern. Even single, targeted attacks can result in major damage; when cybercriminals control and manipulate several nodes in a network, the potential for destruction increases.
