A new computer software package, currently under development, will give the term “personal digital assistant” (PDA) a new meaning, helping users quickly and easily evaluate if they are operating at their mental best.
Tests on hand-held, personal digital assistant devices are being developed so astronauts can conduct quick, self tests to determine their cognitive processes, such as the ability to pay attention. These tests can be used to evaluate how lack of sleep, physical exercise, hormonal variations or even diet affect cognitive function.

“Difficult tasks, such as an astronaut performing a space walk or a surgeon doing a complicated operation, require the utmost attention and vigilance. We’re developing a way for people to test themselves and make sure they are mentally up to the challenge,” said Dr. Stephen Kosslyn, a researcher on the National Space Biomedical Research Institute’s (NSBRI) neurobehavioral and psychosocial factors team. “Test results can help users determine if they need to eat, sleep, exercise, or better focus their thoughts on the task at hand.”
MiniCog, a new software package being developed and tested by Kosslyn’s research team, could help people in many situations determine what they are capable of safely achieving. The program is quick, easy to use, and designed for use on the newest-generation PDA. MiniCog contains nine cognitive tasks that evaluate attention, working memory, problem-solving ability, motor control and ability to switch thinking among cognitive sets. The battery of tasks does not have to be taken all at once, but rather a subset of tests can be used to assess certain aspects of the user’s mental ability at a given time. “Each task takes about two minutes to complete,” Kosslyn said.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
