A new screening test to be piloted in Bristol could help to revolutionise the way children with leukaemia are treated by enabling doctors to fine tune treatment to the needs of each individual patient.

Experts from five centres – Bristol, Glasgow, Leeds, London and Sheffield – will pilot the test for the most common form of the childhood leukaemia – acute lymphoblastic leukaemia (ALL). The team at the University of Bristol and Bristol Royal Hospital for Children is using special technology c

Every living thing needs iron. The strategies some organisms use to accumulate iron can impact the quality of our environment and could be adapted for our use.

Imagine a falconer releasing his falcon to nab pigeons for his dinner. That is somewhat how the bacteria, Azotobacter vinelandii , acquire iron. They release siderophore molecules, called azotobactin, which nabs iron out of m

The collaboration between cardiologist and orthopedist may at first seem novel, if not odd. But just such an interdisciplinary connection at the University of North Carolina at Chapel Hill has yielded potentially useful fruit: a bioengineered, rhythmically beating experimental model of heart muscle.

The new model system is a bioartificial trabeculum, or BAT. Trabecula are thin sections of cardiac tissue within the inner surface of the heart’s main pumping chambers. Although still some

New polymer could prevent burns, food poisoning, traffic accidents

Imagine a fire door that changes color when hot, football jerseys that can tell when a player is overheating, road signs that change color indicating icy road conditions, and food packaging stamps that disappear when products have been kept at room temperature for too long. At the University of Rhode Island, chemists Brett Lucht and Bill Euler and chemical engineer Otto Gregory are working to make these products a real

When physicists sandwiched together different types of semiconductor to create the first transistor in 1947, they made bulky vacuum valves obsolete and so revolutionised the electronics industry. Since then researchers have been pushing the boundaries of semiconductor technology hoping for another revolution. At the 26th International Conference on the Physics of Semiconductors in Edinburgh from 29 July to 2 August, progress towards ultra-high density magnetic recording, and a new branch of nanotech

The long-term use of hormone replacement therapy (HRT) does not increase the risk of endometrial cancer and may even protect the endometrium (the lining of the uterus) from the disease, concludes a study in this week’s BMJ.

In one of the largest long-term studies of its kind researchers from across the UK collected data from 534 postmenopausal women. Before the study began, 364 of the women had taken oestrogen and progestogen hormone replacement therapy in which the two hormones were given s
