Fighting the Flu, Year After Year

Flu vaccines are updated annually to keep up with continual changes in circulating influenza viruses. It is well-established that influenza vaccines are less effective in "mismatched" seasons when the main circulating strains change after the months-long vaccine production process has already begun. However, even in previous years when the vaccine

Asymmetric Sound Absorption Lets in the Light

Many asymmetric absorbers, those that only absorb sound coming in from one direction, are currently based on a single-port system, where sound enters one side and is absorbed before a rigid wall. In this design, however, light and air are unable to pass through the system. But a combined research

Nerves Control the Body’s Bacterial Community

An important breakthrough in deciphering these highly complex relationships has now been achieved by a research team from Kiel University's Zoological Institute. Using the freshwater polyp Hydra as a model organism, the Kiel-based researchers and their international colleagues investigated how the simple nervous system of these animals interacts with the

Genes are Controlled by Nano Footballs Scientists Discover

By placing tiny glowing probes on transcription factors -- special chemicals inside cells which control whether a gene is switched 'on' or 'off' -- researchers gained a remarkable new insight into the way in which genes are controlled. Crucially, they discovered that transcription factors operate not as single molecules as was

Ricin only Lethal in Combination with Sugar

The plant toxin ricin is one of the most poisonous naturally occurring proteins, making it an extremely dangerous bioweapon. Ricin attacks have made the headlines a number of times over the years, including the spectacular "umbrella murder" in London in the 1970s, or more recently the ricin letters addressed to
