Insects develop resistance to engineered crops

...ce to a single toxin," said Shelton. "If an insect gets a jump on one toxin, then it becomes more rapidly resistant to that same toxin in a dual-gene plant. And when one line of defense starts to fail, it puts more pressure on the second toxin in a pyramided plant to control the insect," Shelton added. W...

Study shows how retinoic acid enters a cell's nucleus

...s a basic mechanism of how this protein, CRABP-II, gets into the nucleus, where it can act to suppress tumors." CRABP-II is a member of a group of proteins called intracellular lipid binding proteins (ILBP), which don't have a recognizable NLS. But now researchers have something new to look for -- folds ...

Microscopic brain imaging in the palm of your hand

...e molecules used to mark the tissue. The technique gets rid of the background haze and reduces scattering, because molecules outside the area of interest are much less likely to absorb a pair of photons simultaneously and fluoresce in response. While two-photon microscopy offers an alternative to tradit...

Say what? Bacterial conversation stoppers

...on language does not guarantee the correct message gets through, the researchers discovered. In earlier work, Xavier had found that E. coli both produces and consumes AI-2. In this study, she set up an experiment where multitudes of E. coli first produced then devoured enough AI-2 to dim the lights of...

Lance Armstrong through a physiological lens: hard training boosts muscle power 8%

...ch cycling stroke," it noted. As body matures, it gets "smarter" Coyle said increased muscle efficiency means that "for the same amount of cardiovascular and lung stress Armstrong is producing 8% more power, and yet producing less heat. These results have shown us how to improve already highly trained a...

UIC researchers show protein routes messages in nerve cells

...t to ensure that only the correct type of receptor gets attached. The work by the researchers also identifies the cytoskeleton proteins to which the receptors are tied: actin. "Many researchers have identified proteins that interact with glutamate receptors, but there's never previously been a link foun...

Researchers make 'embryonic-like' stem cells from umbilical cord blood

... the patient," Dr McGuckin said. "Using cord blood gets over that obstacle because we can produce more stem cells and, with a global birth rate of 100 million babies a year, there is a better chance of getting the right tissue type for the many patients out there waiting for stem cell therapy. There is al...

Clearing jams in copy machinery

The findings by O'Donnell and his colleagues show that, because both polymerases are bound simultaneously to the beta clamp, it can pull either of the polymerases out if its toolbelt as needed. O'Donnell and his colleagues propose two explana...

New tooth enamel dating technique could help identify disaster victims

...he enamel samples were analyzed. "Whatever carbon gets laid down in enamel during tooth formation stays there, so tooth enamel is a very good chronometer of the time of formation. "We were surprised at how well it worked," he said. "And if you look at multiple teeth formed at different times, you can ge...

Birds and bats sow tropical seeds

Just how big a role these winged gardeners play is a question ecologists from the University of Illinois at Chicago and several Latin American universities are about to find out by setting up essentially a l...

Grabbing addiction by the tail

With the cellular machinery otherwise occupied, the glutamate receptors stay on the cell surface, where they continue to receive signals. After...

Computer models aid understanding of antibody-dependent enhancement in spread of dengue fever

But there comes a point where the predator gets so good it runs out of prey," explained lead author Derek Cummings, a research associate in the Department of International Health at the Bloomberg School. "We found that antibody-dependent enhancement helps the dengue virus spread faster, but there ...

Gene therapy for muscular dystrophy fixes frail muscle cells in animal model, Stanford study finds

...two advantages: one is that in her method the gene gets inserted directly into the cell's own DNA, which is why the correction is permanent. In some other methods the gene stays outside the DNA and slowly breaks down. The second advantage is that her method doesn't rely on a virus to disperse the DNA and ...
