MIT device draws cells close -- but not too close -- together

...und. This idea quickly evolved into an elegant tool designed expressly for biologists. The device involves two separate comb-shaped pieces coated with living cells. These two pieces can click into place at two settings: One allows cells on the edges of the combs to touch, the other maintains a gap...

New imaging technique tracks traffic patterns of white blood cells

...imflammatory cell behavior, and provide a powerful tool for the development of therapeutics for these diseases," according to Mount Sinai researchers. "Sickle cell anemia was the first disease characterized at the molecular level but there is still no treatment for the acute vascular occlusions which ...

Faster, low cost sequencing technologies needed to drive era of personalized medicine

... - to make genome sequencing a routine diagnostic tool in medical care. The reduced cost may allow doctors to tailor medical treatments to an individual's genetic profile for diagnosing, treating, and ultimately preventing many common diseases such as cancer, heart disease, diabetes and obesity. ASU...

Virginia Tech's System X supercomputer provides super tool for simulation of cell division

...arch), to estimate the 143 parameters. "With a tool like this scientists can spend more time working on the model and less time twiddling parameters," said Tyson. The research is due to appear in 2007 in the Journal of Global Optimization, in the article "Deterministic Parallel Global Parameter Est...

U of MN researchers turn cord blood into lung cells

... the future, the cells could be used as a research tool to better understand lung development and disease. The cells may also be useful as a way to test potential new drugs. To differentiate the lung cells from the cord blood, McKenna and his team first derived the Multi-Lineage Progenitor Cell TM (ML...

Gene key to taste bud development identified

...d her colleagues use this fluorescence marker as a tool for tracking the activity of SOX2 in the esophagus, among other sites. As they worked with the mice, they noticed that specific areas on the tongue and in the back of the mouth lit up, in addition to areas in the esophagus. Further studies, Hogan sai...

One-of-a-kind imaging probe reveals secrets useful for drug discovery

... to examine patients in hospitals, this analytical tool uses much stronger magnetic fields to study smaller samples, allowing scientists to study molecules atom by atom. But what made this particular method unique is not the extreme power of the magnet, which at 600 megahertz is fairly standard, but the ...

Novel experiment documents evolution of genome in near-real time

...e study of experimental evolution can be used as a tool for discovery and analysis, and could even be used to discover bacterial capabilities that would benefit humankind in a variety of ways," said Herring. "There may be a number of biotech companies that want to use this new approach to help design bact...

Living view in animals shows how cells decide to make proteins

...edingly difficult, he said. "This is a powerful tool to apply to mouse genetics to learn when and where in the animals' bodies alternative splicing decisions are made and, eventually, to learn what factors are critical in making these decisions," Garcia-Blanco said. "Given the importance of alternat...

Molecular atlas provides new tool for understanding estrogen-fueled breast cancer

...ch control regions, provides scientists with a new tool for understanding how genes are regulated, and may eventually help doctors match patients with treatments that are most likely to be effective for them and overcome the problem of resistance to current hormone therapies, the study authors say. The ...

New way of tracking muscle damage from radiation

...ic resonance imaging (MRI) could become a valuable tool for predicting the risk of muscle injury during and following radiation therapy, according to investigators at St. Jude Children's Research Hospital. The researchers report that MRI can spot the immediate injury done by radiation therapy to the mu...

Fight weeds with plant pathogens

... plant pathogens may be a successful, eco-friendly tool for managing weeds. "The use of plant pathogens to suppress weeds is considered as one of the alternative weed control options for areas or production systems where the use of chemical herbicides is not permitted or feasible," said Erin Rosskopf...

'Protecting virus' offers instant flu protection and converts flu infections into their own vaccines

...e cell. It thus promises to be a highly effective tool when combating the spread of any new strain of virus, as well existing strains. One could give it as a preventive measure without the need to tailor it to a particular flu strain or mutation. This has obvious benefits when dealing with the sudden ou...

A valuable fly for research into disease

...cus on the use and exploitation of Drosophila as a tool to study human diseases. The event is organized by...lcohol, cocaine and nicotine. Drosophila is a key tool for studying certain aspects of cancer, and research into the development and proliferation of tumou...

Researchers identify neurons that assign value during learning

...lluminating fruit fly larvae with blue light. This tool allowed the researchers to test whether such an activation of certain neurons can actually substitute for external stimuli--for example, reward or punishment--in an associative-learning experiment. The researchers found that if an odor is presented w...

'Failed' experiment yields a biocontrol agent that doesn't trigger antibiotic resistance

...overy that led to the creation of a new biological tool for destroying bacterial pathogens - one that doesn't appear to trigger antibiotic resistance. The discovery also led to the startup of a promising new biotechnology firm that has already brought Wisconsin a dozen new, high-paying, highly skilled j...

Brown scientists map structure of DNA-doctoring protein complex

...DNA complex," Sun said. "Biologists now have a new tool to help them understand a variety of these complexes, including ones that control cell division, gene expression and DNA replication. So this technique represents a big advance." ...

Gene signature assesses breast cancer outcomes
