Cognitive neuroscientists have shown that babies have an abstract numerical sense, as demonstrated by their ability to match the number of voices they hear to the number of faces they expect to see. This numerical perception across senses demonstrates that babies have a truly abstract sense of numerical concepts -- and not just one that is a function of a particular sense -- even before they learn to speak. Previous experiments on this topic have yielded conflicting and equivocal results, said the researchers.
The researchers, Kerry Jordan and Elizabeth Brannon of Duke University, published their findings the week of Feb. 13-17, 2006, in the Proceedings of the National Academy of Sciences. Jordan is a graduate student and Brannon is an assistant professor in Duke’s Center for Cognitive Neuroscience and Department of Psychological and Brain Sciences. The research was sponsored by The National Institute of Mental Health, The National Science Foundation and the John Merck Fund.
In their study, Jordan and Brannon used the same basic experimental design that they had previously used to demonstrate that monkeys show numerical perception across senses http://www.dukenews.duke.edu/2005/06/BrannonCurrBio.html. In those experiments, the researchers, collaborating with colleagues at the Max Planck Society, presented the monkeys with the sound of two or three animals making a natural "coo" sound. At the same time they gave the monkeys a choice to look at video images of either two or three monkeys cooing. The researchers found that the monkeys overwhelmingly chose to look at video images that matched the number of monkeys they were hearing.

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.
