Novel technology detects human DNA mutations

...r drug sensitivity.To do so, Nanosphere scientists employ a two-step process calledClearReadTM technology. This method sandwiches a target DNA SNP segment between two oligonucleotide sequences to greatly increase detection specificity and sensitivity. One segment identifies any mutations in the DNA and the ...

Designing vaccines by computer

...ments to trigger an immune response. They can then employ computers to search for similar sequences in the thousands of sequences now available. When the search finds something promising it can be experimentally tested to see if it will trigger a response. Dr Darren Flower, an international leader in this ...

Experiment station researchers to explore genome of disease-fighting fungus

...ason. "You also might be able to more effectively employ sustainable practices such as low till agriculture," said Wilkinson, who is researching the ecological aspects of the fungus. "You've got Trichoderma present to combat the pathogens that remain in the soil when you incorporate low till. In theory, it...

Ants, not evil spirits, create devil's gardens in the Amazon rainforest, study finds

...bactericidal and fungicidal properties." The ants employ a very effective system of lethal injection, notes Gordon, associate professor of biological sciences at Stanford. "The system harnesses two fundamental tools:formic acid, which many ant species use for other purposes, and the basic circulatory syste...

New plant DNA libraries provides massive boost to world's plant researchers

...DNA of each species. Genomic DNA libraries usually employ "restriction enzymes" to cut up the DNA but this method may preferentially select only certain regions of DNA and exclude other regions from the final plant "library". The techniques used by the Warwick researchers remove this limitation and make the...

Firefly protein lets researchers monitor molecule linked to cancer

...itor protein-protein interactions. Researchers can employ an instrument known as an in-vivo bioluminescence camera to take real-time measurements of light from luciferase in cell cultures and in cells within live animals. To use the firefly protein to monitor IKK, Gross altered cell lines to genetically fu...

Discovery that bacterium is phosphate gourmet key clue to what makes it most social of bacteria

...detector - giving the bacterium even more tools to employ as a phosphate gourmet. Dr Whitworth also has evidence that the surprising extent of interaction between the three and a half phosphate signalling pathways is also found among the other 140 plus signalling pathways of the bacterium. If three and hal...

Researcher uncovers details of how cancer spreads

...ding a mechanism called endocytosis -- which cells employ to let materials enter through the cell membrane. The researchers used a protein called v-Src derived from an oncogenic virus, which has the ability to transform a normal cell into one with many features resembling those found in cancer cells. While...

The bioweapon is in the post

...ed up as suspicious, and that means companies must employ biologists to carefully examine any matches that crop up. The need for expert human checks may be one factor deterring some companies from screening orders. Others like to reassure customers who may be worried about commercial confidentiality that t...

Anthrax spores may survive water treatment

...g water treatment facilities should be prepared to employ alternate disinfection methods in the unlikely event of the release of anthrax in the water supply. Researchers report their findings today at the 2006 ASM Biodefense Research Meeting. "The purpose of this study was to determine the fate of anthra...

A new way of looking at molecular motors

...m define some of their new categories. Organisms employ all three types of motors at the same time, but in different proportions. For example, yeast uses six kinesins, five myosins, and one dynein while mammals have genes for more than 40 kinesins, 40 myosins and more than a dozen dyneins. Genetic and ac...

Confidence in memory performance helps older adults remember

...e they can control their memory are more likely to employ mnemonic strategies that help keep memory fit despite the march of time. These are the conclusions of a new Brandeis study published in the Journals of Gerontology: Psychological Sciences. The study demonstrates a link between actual cognitive funct...

New Research Shows Artificial Light at Night Stimulates Breast Cancer Growth in Laboratory Mice

...er mimics sunlight,?added Stevens. “Companies that employ shift workers could introduce lighting that allows the workers to see without disrupting their circadian and melatonin rhythms.? ...

Case Western Reserve University researchers find protein associated with brain cell death

...eaction. "We have recently shown that microglia employ a multi-receptor cell surface complex to detect and respond to amyloid –beta fibrils," the researchers write. "These receptor elements act in concert to stimulate intercellular signaling cascades as well as initiate a novel type of phagocytosis (cel...

First-ever genomic test predicts which lung cancer patients need chemotherapy to live

...ncer tumors will eventually become obsolete." To employ the test, physicians take a sample of the tumor as it is removed during surgery. They extract its "messenger RNA," which represents the activity of thousands of genes in the tumor. Messenger RNA translates a gene's DNA code into proteins that run the...

Dominant meerkats render rivals infertile

...ch on cooperative species was that dominants don't employ tactics of this kind. It's not yet clear whether meerkats are just unusual in this regard, or whether stress-related suppression is actually a more widespread phenomenon in animal societies than was previously recognised". Dr Andrew Young's researc...

Harmful Algal Blooms monitored from space in Chile

...uding one death. Just like plants on land, algae employ green-pigmented chlorophyll for photosynthesis -- the process of turning sunlight into chemical energy. The chlorophyll collectively tints the colour of the surrounding water, providing a means of detecting these tiny organisms from space with dedica...

Targeted virus compels cancer cells to eat themselves

...ls. Autophagy is a protective process that cells employ to consume part of themselves when nutrients are scarce or to destroy some of their organelles to recycle their components. A double membrane forms around the material to be consumed, then everything inside is digested. Kondo and colleagues showed t...

Sandia research to focus on early detection of harmful algal blooms

...., site. In addressing the HAB problem, they will employ laser-induced fluorescence and other separation methods inherent in Sandia's µChemLab(tm) ("Micro" ChemLab) technology. Along with a small team of Sandia colleagues and external collaborators, they have commenced with the research, which could lead t...

Better sludge through metagenomics

... gallons of sewage annually. Many treatment plants employ specialized bacteria to remove the nutrient phosphorus, in an effort to protect lakes and rivers from eutrophication, a deterioration of water quality characterized by excessive algae blooms. Accumulibacter play a vital role in wastewater management,...
