*Beam me up an antibiotic*
Scientists are studying the way that bacteria eject antibiotics from their cells to help develop new drugs that could foil some of the world's biggest bacterial killers. Studying the way that membrane protein transporters, which act as "drug pumps", help bacteria resist medical treatments could help the team from the University of Glasgow develop new screening tools that will ultimately help in the development of new drugs.

*Turkeys give thanks for new virus research*
Last summer, scientists at the Institute for Animal Health discovered that a virus thought only of significance in North America had infected British turkeys. The researchers have now begun a three-year study of the virus to find out the extent of infection in the British turkey flock and look at the effect of the virus on bird welfare and mortality.

*Why stressed hens lay inferior eggs*
Scientists think they've cracked the problem of why stressed hens lay inferior eggs. In the 20 hours it takes to make an egg, tiny amounts of protein are precisely secreted into the layers of calcium carbonate that form the eggshell. In hens that are stressed, the birds delay the laying process and these secretions become more acidic, resulting in eggs that are nutritionally OK but have a powdery 'bloom' on their surface that reduces their value. Researchers hope that this may lead to a simple stress detection method for commercial layers.

*Functional genomics - it's more than just buying the kit*
Investigations into river pollution, rice production and food poisoning have all been given a welcome boost by the 18-month-old Functional Genomics Laboratory at the University of Birmingham. Delegates at a recent industry-backed seminar heard how the University is providing data for a wide range of projects and contributing to one of the most dynamic fields in modern biology.
