The researchers found that adults aged 59 to 81 took significantly longer than college students to cross a simulated street while talking on a mobile phone, and their heightened cautiousness in initiating crossing did nothing to improve their safety. Older adults on cell phones also were more likely to fail to cross in the time allotted for the task.
The findings, from researchers at the University of Illinois, appear in the journal Psychology and Aging.In the study, 18 undergraduate students (aged 18 to 26 years) and 18 older adults crossed simulated streets of varying difficulty while either undistracted, listening to music or conversing on a hands-free cell phone. The older adults were significantly impaired on the most challenging street-crossing tasks while also engaged in a second activity, with the most pronounced impairment occurring during cell phone conversations. The younger adults showed no impairment on dual-task performance, the researchers found.
"Combined with our previous work, the current findings suggest that while all pedestrians should exercise caution when attempting to cross a street while conversing on a cell phone, older adults should be particularly careful," Neider saidEditor's notes: To reach Art Kramer, call 217-244-8373; e-mail firstname.lastname@example.org.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
