Selenium may slow march of AIDS

Increasing the production of naturally occurring proteins that contain selenium in human blood cells slows down multiplication of the AIDS virus, according to biochemists.

Screening for Down's syndrome

A new national screening strategy in Denmark has halved the number of infants born with Down's syndrome and increased the number of infants diagnosed before birth by 30 per cent.

Cause of leukaemia relapse

New study finds the majority of acute lymphoblastic leukaemia relapse cases arise from a cell already present at the time of diagnosis.

A novel Staph target

Researchers have uncovered how a bacterial pathogen interacts with the blood coagulation protein fibrinogen to cause methicillin-resistant Staphylococcus aureus infections.

TB drug explodes bacteria

An international team of biochemists has discovered how an experimental drug unleashes its destructive force inside the bacteria that cause tuberculosis.

Gene regulates blood sugar

When mice that lack steroid receptor-2 (SRC-2) - a master regulator gene called a coactivator - fast for a day, their blood sugar levels plummet.

Keeping chromosomes from cuddling up

Researchers have found the molecular machines in fruit flies that yank chromosomes, the DNA-carrying structures, apart when necessary.

Antibiotics lead drugs in liver injury

Antibiotics are the single largest class of agents that cause idiosyncratic drug-induced liver injury, reports a new study in Gastroenterology.

Good cholesterol not good enough

Researchers challenge the conventional wisdom that simply having high levels of good cholesterol and low levels of bad cholesterol is necessary for good heath.

Smallpox vaccination effective for decades

Researchers found that lifetime protection is obtained from just one vaccination, even when that vaccination occurred as much as 88 years ago.

Scientists developing food allergy treatment

A team of scientists from across Europe are embarking on new research to develop a treatment for food allergy.

Keeping killer T cells in prime shape

Researchers have found multiple receptors on the outside of the body's killer immune system cells which they believe can be selectively targeted to keep the cells in superb condition.

Cell movements totally modular

A study describing how cells within blood vessel walls move en masse overturns an assumption common in the age of genomics - that the proteins driving cell behaviour are doing too much multitasking.

World AIDS Day 2008 recap

In recognition of World AIDS Day 2008, we look back at articles published during the past year on Scientist Live relating to HIV and AIDS research from Europe and the rest of the world.

Gene which protects against lung cancer identified

A study led by researchers at The University of Nottingham has identified a gene that protects the body from lung cancer.

Synapse versatility investigated

Up to now, only the receiving side of a synapse was believed to play an active role in this reorganisation of the brain, which is thought to underlie our ability to learn but also to forget. Scientists now say that is incorrect.

New test for depression

A new universal test to predict the risk of someone succumbing to major depression has been developed by University College London researchers.

Nuclear science for food security

The International Atomic Energy Agency today called for increased investment in a plant breeding technique that could bolster efforts aimed at pulling millions of people out of the hunger trap.

Interferons helps cells remember how to fight

Scientists have determined that the immune-system protein interferon plays a key role in teaching the immune system how to fight off repeated infections of the same virus.

Stressing the brain

Researchers using functional MRI (fMRI) have determined that the circuitry in the area of the brain responsible for suppressing memory is dysfunctional in patients suffering from stress-related psychiatric disorders.
