Children exposed to cocaine before birth show subtle but discernible differences in their ability to plan and problem-solve once they reach school age, University of Florida researchers report.
Still, most fare far better in the first few years after birth than many experts once predicted, contradicting the notion that as a rule, cocaine-exposed infants would be born with devastating birth defects or miss major developmental milestones. "I think the early information we had was that these children might be irreversibly damaged - that they would potentially have lots of problems in school, that they might have lots of behavior problems, that they might have problems thinking and learning," said UF neonatologist Marylou Behnke, M.D.
Instead, UF researchers write in the April online issue of the Journal of Pediatric Psychology, prenatal cocaine exposure is linked to smaller head circumference at birth and to less optimal home environments, which in turn have direct yet mild effects on developmental outcome at 3 years of age. Those effects persist at ages 5 and 7, once more demands are placed on the children during the formal school years, according to related findings the researchers presented at the recent annual meeting of the Society for Research in Child Development.

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...
