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.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
