A microelectronic sensor may alert doctors to bacterial hazards.
Smart bandages could soon alert doctors to the presence of certain bacteria in a wound by glowing different colours. Researchers in the United States have created a tiny device that emits faint light of two colours in response to two types of bug 1 .
Benjamin Miller, of the University of Rochester in New York State, and colleagues hope that a refined sensor might ultimately generate an instant an
Scientists have long noted that people suffering from Parkinsons disease commonly exhibit a specific personality type characterized by, among other things, a lower-than-average tendency to seek out new experiences. In explanation, investigators suggested that this trait was rooted in an inability to reap the pleasurable rewards of increased dopamine levels normally brought about by new stimuli because the disease destroys the neurotransmitter. Previous studies of personality and dopamine activi
Researchers find two new leads for anti-anthrax drugs.
As fears over bioterrorism attacks spiral, researchers are making progress towards better anthrax drugs – but these are unlikely to reach the drugstore soon.
Of ten confirmed anthrax cases in the United States by Monday, four have been of the severe, inhaled form against which antibiotics often fail. By the time drugs destroy the bacteria responsible, Bacillus anthracis, the organisms have released enough lethal toxin t
Study questions whether mammography saves lives.
Breast-cancer screening programmes may not save lives, according to a new examination of clinical trials. The controversial findings have led to calls for a re-evaluation of the routine monitoring procedure undergone by numerous women.
Mammography, X-ray breast imaging, is used in Europe and the United States to catch cancers early. “We’ve based a national screening programme on a set of results which do not stand up to scrut
A large, long-term study confirms that diet can help some epileptic children.
A strict high-fat, low-carbohydrate, calorie-restricted diet reduces seizures in children with intractable epilepsy. So concludes the largest and longest trial of an eating plan that was first suggested almost a century ago.
For about two years, epileptic youngsters on a ’ketogenic diet’ eat 25% less than normal and consume 90% of their daily calories as fats. They take vitamins and minerals to avo
About half of all patients with hereditary breast or ovarian cancer have mutations in a gene called BRCA1. Now the first images of the protein the gene encodes, BRCA1, are helping researchers work out how the mutations cause human disease.
The pictures reveal fine detail of how BRCA1 interacts with other proteins. Such information should help researchers work out how BRCA1 prevents cells becoming cancerous. They suspect that it is involved in DNA repair, controlling cell division and regula
