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

... 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

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.
