DNA technique measures suitability of soil for onion crops

...n November 2005. The system quickly and accurately measures soil samples at the molecular level. In a series of comparative trials, the molecular test had a higher detection rate than the traditional microscopic investigation for both the stem nematode and onion white rot. Each year thousands of soil sample...

Technique offers new view of dynamic biological landscape

...his colleagues plan to develop better quantitative measures of the effects of epistatic interactions and to extend their technique to other organisms, ultimately to humans. In addition to offering important basic insights into the roles of proteins and genes, E-MAPs will also contribute to understanding evo...

UCR environmental scientists propose chemical solution to cleaning California's Salton Sea

...e blooms in the Salton Sea," Amrhein said. Unless measures are taken to clean the Salton Sea, evaporation will result in the sea being too salty for fish, resulting also in the loss of fish-eating birds frequenting an area that is home also to several endangered bird species and visited by millions of waterf...

Cheap, rapid hand-held check for HIV

...rsrand in Johannesburg, South Africa. The sensor measures the quantity of key immune cells called CD4+ cells in the blood. A gradual depletion of CD4+ cells, which orchestrate the immune response to tumours and infections, is a sure sign that HIV is damaging a person's health: some clinical definitions of A...

'Good' bacteria could save patients from infection infection by deadlier ones

...ck patients. This is so because these "preventive" measures destroy beneficial bacteria, while at the same tim... advanced antibiotics and most rigorous antiseptic measures are taken. One must ask, says Spigelman, "why more of the same does not seem to be working?" The app...

UCLA imaging study of children with autism finds broken mirror neuron system

...child with autism was tested using two independent measures (the Autism Diagnostic Observation Schedule -- Generic, and the Autism Diagnostic Interview). The study shows that unlike typically developing children, children with autism have virtually no activity in the pars opercularis of the inferior frontal ...

MRSA use amoeba to spread, new research shows

The MRSA 'superbug' evades many of the measures introduced to combat its spread by infecting a common single-celled organism found almost everywhere in hospital wards, according to new research published in the journal Environmental Microbiology. Scientists from the University of Bath have shown ...

Environmental tobacco smoke linked to behavior problems in children and pre-teens

...ntervention study. Dr. Yolton included additional measures to assess child behaviors. To measure exposure to environmental tobacco smoke, Dr. Yolton measured levels of cotinine in the children's blood. Cotinine is a substance produced when nicotine is broken down by the body and can be measured in blood, u...

Whole-genome study at Johns Hopkins reveals a new gene associated with abnormal heart rhythm

...udden cardiac death here at Hopkins." QT interval measures the period of time it takes the heart to recover from the ventricular beat - when the two bottom chambers of the heart pump. Corresponding to the "lub" part of the "lub-dub" pattern of the heartbeat, an individual's QT interval remains constant. This...

Computers to save unique type of American red squirrel

... Mount Graham Red Squirrel. Although conservation measures are already in place, concerns about the animal's viability have increased as numbers have more than halved since 1999, dropping from 562 to a recent low of 214. As with the British red squirrel, one of the Mount Graham red squirrel's threats is an...

New RNAi tools enable systematic studies of gene function

...the high-throughput techniques and quality-control measures required for such genome-scale studies. "It is a distinct challenge to achieve consistent and cost-effective RNAi methods and we placed a strong emphasis on this part of the process," said David Sabatini, member of Whitehead Institute for Biomedical ...

Mice studies illustrate potential of chimp/human antibodies to protect against smallpox

...important finding in the race to develop effective measures against a potential bioterror attack involving the deadly smallpox virus," says NIH Director Elias A. Zerhouni, M.D. "It is imperative that we have effective treatments available that everyone could use in the event of a bioterror attack," says NIAI...

Infections could contribute to adult brain tumours

...y be a step towards developing better preventative measures for cancer and may also result in better treatment. Dr Richard McNally, of Newcastle University's School of Clinical Medical Sciences (Child Health), said: "Very little is known about the cause of brain tumours and we think our research brings us c...

New nano-canary in the nanotoxicology coalmine: The body itself

...ological response," said Weber. FTIR spectroscopy measures a broad spectrum of chemical bonds and will provide information that is complementary to genomic and proteomic approaches. FTIR spectra are captured in minutes in live cell studies, offering a tool to rapidly detect whether nanoparticles are biologi...

Protecting endangered species helps reduce poverty

...were. The community strongly supports conservation measures to promote ecotourism, and both turtle and tourist numbers have climbed over the past 30 years. Community forestry efforts in parts of Nepal have led to the restoration of vital habitat corridors for the survival of tiger populations living there. ...
