Developed at MGH, digital tomosynthesis may better identify malignant lesions

A new approach to mammography, developed by researchers at Massachusetts General Hospital (MGH), holds the potential for greatly improving the detection of breast lesions and the ability to predict whether they are benign or malignant. In a presentation earlier this month at the scientific assembly of the Radiological Society of North America (RSNA), Elizabeth Rafferty, MD, of the MGH Breast Imaging Service

For every warm-blooded human who has ever taken an online poll or signed up for free web-based email, there are legions of computer-automated Internet robots, or “bots,” trying to do the same thing.

A clever security system designed to stop these bot programs – which contribute to the Internet equivalent of computer-generated telemarketing calls – has now been cracked by a pair of computer scientists from the University of California, Berkeley.

Results of a 2 ½ year study led by doctors at Dartmouth-Hitchcock Medical Center could have implications for the nation’s decreasing blood supply.

In an article published in the December 11 issue of the Journal of the American Medical Association (JAMA), Drs. Howard L Corwin and Andrew Gettinger describe the effects of administering recombinant human erythropoietin (rHuEPO) to critically ill patients. Significantly, they found that use of the hormone, which stimulates red blood

Latest research at Oxford University’s Glycobiology Institute has provided new leads towards the development of an oral contraceptive for men. The advantages of the substance at the centre of the research, an alkylated imino sugar (NB-DNJ), are that it does not affect reproductive hormones, its effects are easily reversed and it is undergoing clinical evaluation in other contexts.

NB-DNJ interferes with the development of sperm cells in such a way that they become very poor swimmers, highly

Micro-sensors, developed by the CEIT Technology Centre with the help of Gas de Euskadi, operate by detecting gas leaks and reducing the risks of poisoning through the inhalation of carbon monoxide gas.

Through research involving help from Gas de Euskadi, CEIT has developed a system based on micro-sensors that can detect domestic gas leaks. The increasing use of natural gas in homes, the future regulations for carbon monoxide detection in domestic situations and the growing demand for

The problem is intensive agriculture. Nowadays, some farmers have too many heads of cattle in comparison with their land under tillage. Due to this, purines (manure and stable/barn droppings) are applied in high concentrations on these soils, above all on those around the barns. Also, in order to feed the land which is further afield, farmers buy mineral feeds. Great problems for the environment arise out of the application of high quantities of mineral fertilisers and purines.
