Taking something of a back-to-the-future approach, biologists from Boston University have looked into the past to find that flowering plants growing today blossom more than a week earlier than a century ago. Their findings, being presented at the Society for Conservation Biologys annual meeting in New York City July 30 – August 2, show that among the plants studied in Bostons Arnold Arboretum, flowering times have moved forward over the decades, with the plants flowering eight days earlier on average from 1980 to 2002 than they did from 1900 to 1920.
What has influenced this rush to flower? Primarily temperature, says Richard Primack, a BU biology professor and head of the research team. Since 1885, Bostons mean annual temperature has increased 1.5 degrees Celsius or nearly 3 degrees Fahrenheit. According to Primacks team, this increase in mean temperature, especially in the months February through May, has influenced the shift in flowering times.
In addition to its scientific insights, the study may provide a model for public participation in climate change research. The relatively low-tech, data-from-the-community protocol used by the team might open such studies to participation by botanical gardens, zoos, museums, or even individuals who, over the years, have carefully collected and tended records on how biological organisms respond to their environment.

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...
