Study says sleep improves by more than a third
Sleep, a vital ingredient in life, can sometimes become difficult as humans get older. But a recent study by researchers at Case Western Reserve Universitys Frances Payne Bolton School of Nursing and the Buddhist Tzu-Chi General Hospital in Taiwan shows that listening to soft music at bedtime will help older adults sleep better and longer.
The research, published in the February 2005 edition of The Journal of Advanced Nursing, found that older people with sleep problems reported a 35 percent improvement after they started listening to 45 minutes of soft music before bedtime. Researchers Hui-Ling Lai, director of the Community Health Center at the Buddhist Tzu-Chi General Hospital, an assistant professor at Tzu Chi University in Taiwan and Case alumna, and Marion Good, professor of nursing at Case, studied the sleeping patterns of 60 people aged 60-83, randomly designating them in equal numbers into a music group and a control group. They discovered that the 30 who had listened to carefully selected music experienced physical changes that aided restful sleep. These included lower heart and respiratory rates.

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...
