The popular media has portrayed men and women as psychologically different as two planets – Mars and Venus - but these differences are vastly overestimated and the two sexes are more similar in personality, communication, cognitive ability and leadership than realized, according to a review of 46 meta-analyses conducted over the last 20 years.
According to the meta-analysis of studies on gender differences reported on in the current issue of the American Psychologist, males and females from childhood to adulthood are more alike than different on most but not all psychological variables, said psychologist Janet S. Hyde, Ph.D., of the University of Wisconsin in Madison. Psychological differences based on gender were examined in studies that looked at a number of psychological traits and abilities to determine how much gender influenced an outcome. The traits and variables examined were cognitive abilities, verbal and nonverbal communication, social or psychological traits like aggression or leadership, psychological well-being like self-esteem, motor behaviors like throwing distance and moral reasoning.
Gender differences accounted for either zero or a very small effect for most of the psychological variables examined, according to Hyde. Only motor behaviors (throwing distance), some aspects of sexuality and heightened physical aggression showed marked gender differences.

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...
