MEMS thermal sensor detects pre-atherosclerotic lesions
— 17:37 GMT | HealthA new study published in the Annals of Biomedical Engineering shows that a MEMS thermal sensor deployed by an angiogram catheter can detect the earliest stages of atherosclerosis. The MEMS thermal sensor used convective heat transfer to detect pre-atherosclerotic regions of arteries that otherwise showed no clinical signs of atherosclerosis…

Accurate measurement of radioactive thoron possible at last
— 17:31 GMT | Technology'Many people are now saying: 'Is it really that easy? Then why didn't anyone think of it a long time ago?' But you have to have the right idea at the right time,' says Annette Roettger, physicist at the Physikalisch-Technische Bundesanstalt (PTB), in a pleased way. Annette Roettger and her scientific team managed to do something that was previously thought to be impossible: they developed a primary standard for the measurement of short-lived radioactive thoron. Thoron measuring instruments from all over the world will now be calibrated at this unique device which is currently the only one of its kind in the world. This is the basis for accurate measurements of radioactive gas, which occurs naturally in the ground, can collect in living areas and whose progenies are considered carcinogenic…
Genome sequencing used to assess a novel form of Clostridium botulinum
— 17:28 GMT | HealthScientists on the Norwich Research Park have sequenced the genome of a novel strain of Clostridium botulinum, one of the most dangerous pathogens known to man. The strain produces an unusual botulinum neurotoxin, known as type A5 neurotoxin, which was isolated by the Health Protection Agency (HPA), following a case of wound botulism…
Older parents are happier with more children
— 17:25 GMT | Health'Children may be a long-term investment in happiness,' says MPIDR demographer Mikko Myrskylae. Together with Rachel Margolis from the University of Pennsylvania in Philadelphia, USA, he published the new study in the latest issue of the journal 'Population and Development Review.' It shows a global trend: while for parents under 30 the level of happiness decreases with the first and each additional child, mothers and fathers aged 30 to 39 feel as happy as childless peers until they have four children or more. From age 40 onwards parents are even more content than childless couples are unless they have more then three children. Mothers and fathers over 50 are generally happier than their childless peers, no matter how numerous their offspring…

Ageing in place preserves seniors' independence, reduces care costs, MU researchers find
— 17:16 GMT | HealthAmerica's 75 million ageing adults soon will face decisions about where and how to live as they age. Current options for long-term care, including nursing homes and assisted-living facilities, are costly and require seniors to move from place to place. University of Missouri researchers have found that a new strategy for long-term care called Ageing in Place is less expensive and provides better health outcomes…
Protecting ecosystems, pollution remediation goals of research at UH
— 17:13 GMT | EnvironmentCleaning up pollution, protecting soil from erosion and maintaining species-rich ecosystems are some of the goals of a computational ecology project by a University of Houston (UH) scientist and his team. Published recently in a top journal, the work sheds light on a new method to speed up research in the ecology of plants…
