US researchers have discovered a mechanism that will improve understanding of the memory loss caused by Alzheimer's disease. They found that the protein that is known to build up in the brains of Alzheimer's patients, amyloid-beta (A-beta), overexcites the brain networks responsible for learning and memory. Senior author Dr Lennart Mucke said: "We were really surprised by these findings because A...

Bacteria geared to oxygen-free environments can be used to target cancer tumours, scientists said today. Anaerobic bacteria are an ideal agent for treating cancer because the majority of solid tumours contain areas of low oxygen or dead tissue. The medical community is keen to develop gene therapies, since radiotherapy and chemotherapy are ineffective for about half of cancer sufferers....

Eating whole-grain products at breakfast time can help keep blood sugar levels in check throughout the rest of the day, a new study has revealed. Combining low GI (glycemic index) and indigestible carbohydrates, grain products are insulin efficient and induce a feeling of satiety. The dissertation from the Faculty of Engineering at Lund University offers hope for the management of metabolic...

Following the publication of new research into the effects of food colouring on children's behaviour, the Food and Drink Federation (FDF) has highlighted the measures industry is taking to reduce the possible effects on behaviour. A study carried out at Southampton University, on behalf of the Food Standards Agency (FSA), found that consuming certain mixes of artificial colourings as well as...

Fatty deposits in the hearts of pre-diabetic people can be detected long before symptoms appear using a simple imaging technique developed by US researchers. The technique captures the signal from a beating heart as a patient resides in an ordinary magnet used for magnetic resonance imaging (MRI) scanning. Previous studies had shown that fat builds up in the hearts of people with heart failure or...

New research has revealed that damage to vision caused by a stroke can be reversed by the body reorganising the brain. In a study of a 51-year-old man six months after he had suffered a stroke, scientists found that an area of his brain that had stopped receiving signals from the eyes due to the stroke was responding to signals formerly managed by adjacent brain areas. Dr Shimon Ullman, of the...

Studying highly-detailed images of fruit flies is giving scientists insights into human brain function. Using an imaging technique called optical projection tomography, scientists from the Medical Research Council have generated 3D images of the inside of a fruit fly for the first time. Lead researcher Dr Mary O'Connell said that her team had used the images to build upon existing knowledge about...

Smokers have a higher chance of developing Alzheimer's disease or dementia, according to a new study. The seven-year study of nearly 7,000 people age 55 and older found that current smokers were 50 percent more likely to develop dementia than people who had never smoked or had done so in the past. Study author Dr Monique Breteler said: "Smoking increases the risk of cerebrovascular disease, which...

Cutting salt content to make foods healthier does not increase the risk of spoilage by bacteria, scientists said today. Scientists from the University of Limerick in Ireland assessed safety levels of reduced salt foods by studying the behaviour of different strains of food spoilage bacteria. The link between high salt consumption and heart disease has led to food manufacturers lowering salt...

Using deodorants might increase a woman's chance of developing breast cancer, British scientists have revealed. Aluminium, which is used as an antiperspirant in most deodorants, was found in breast tissue taken from breast cancer patients who had undergone mastectomies. Researchers found "significantly higher" levels of aluminium in the underarm region of the breast where antiperspirants are...
