Using a gene resurrected from the virus that caused the 1918 Spanish influenza pandemic, recorded historys most lethal outbreak of infectious disease, scientists have found that a single gene may have been responsible for the devastating virulence of the virus.
Writing today (Oct. 7, 2004) in the journal Nature, virologist Yoshihiro Kawaoka of the University of Wisconsin-Madison and the University of Tokyo, describes experiments in which engineered viruses were made more potent by the addition of a single gene. The work is evidence that a slight genetic tweak is all that is required to transform mild strains of the flu virus into forms far more pathogenic and, possibly, more transmissible.
The results of the new work promise to help scientists understand why the 1918 pandemic, a worldwide outbreak of influenza that killed 20 million people, spread so quickly and killed so efficiently, says Kawaoka, who has studied influenza viruses for 20 years. The finding also lends insight into the ease with which animal forms of the virus, particularly avian influenza, can shift hosts with potentially catastrophic results.

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...

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.
From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
