Test unravels history of infection
By Jonathan Ball
BBC News


US researchers claim to have developed a single test that is able to identify past exposure to every known human virus infection, using a drop of blood. The technique decodes the infection history imprinted in our immune response. The scientists hope that the test will eventually provide important insight into how viruses contribute to development of a range of diseases. {  More... }


Roadside verges 'last refuge for wild flowers'
By Helen Briggs
BBC Environment correspondent


More than 700 species of wild plants - almost half of the native flora of the British Isles - are found on road verges, according to a study. Many plants once found in meadows now only thrive beside roads, where they provide essential habitat for insects, says charity Plantlife International. But it says one in 10 of the plants is at risk of extinction, in part because councils cut verges too early. {  More...  }


Your viral infection history in a single drop of blood
Howard Hughes Medical Institute (HHMI)


New technology makes it possible to test for current and past infections with any known human virus by analyzing a single drop of a person's blood. The method, called VirScan, is an efficient alternative to existing diagnostics that test for specific viruses one at a time.

Researchers find speedometer in the brain
DZNE - German Center for Neurodegenerative Diseases

Neural circuits in the brains of mice that are pivotal for movement and navigation in space have been identified. These nerve cells that are presumed to exist in a similar form in humans, give the start signal for locomotion and also supply the brain with speed-related information. {  More...  }


New evidence emerges on the origins of life
University of North Carolina Health Care


New research shows that the close linkage between the physical properties of amino acids, the genetic code, and protein folding was likely the key factor in the evolution from building blocks to organisms when Earth's first life was emerging from the primordial soup.
