Researchers use multiphoton microscopy to watch chromosomes in action

...vered that HSF activators bind to hsp70 genes much longer than previously thought before being replaced with new HSFs, which raises new questions about the mechanisms of gene transcription. The technique also may offer a new tool for researchers across the biological sciences. Webb says it marks the succes...

New biologic treatment for tennis elbow may replace surgery for chronic sufferers

...ko evaluated 140 patients who had tennis elbow for longer than 3 months and had scored at least a 60 of 100 using a visual analog scale (a continuum on which a person rates the severity of his/her pain: 0 = no pain; 100 = maximum pain). They all had completed a course of physical therapy and had tried som...

Plutonium or greenhouse gases? Weighing the energy options

...s an enormous undertaking that probably would take longer than the 50 years that experts say we have in which to come up with solutions to global warming, Ewing said. Even if they could be built and brought online quickly, that many power plants would generate tens of thousands of metric tons of additiona...

New path from estrogen to survival in breast cancer cells described

...mportant to us," Yeh said. "The reason people live longer is that they don't develop cancer as readily." Players in this newly defined pathway are: BCA3, which had no known function. NEDD8, a protein that can bind to other proteins and alter their function. SENP8, a protease (enzyme) that can break...

MIT creates 3-D scaffold for growing stem cells

...lds particularly interesting is that cells survive longer and differentiate better without additional soluble growth factors," Zhang said. "This suggests that extracellular microenvironments may play a more important role for cell survival and for carrying out cell functions than previously thought." The ...

Microcapsules like it hot and salty

...l becomes thicker and denser. The molecules can no longer move through it and are enclosed inside. If the hollow spheres shrink, the polymer walls also soften when heated. However, there are so many equivalent charges in the capsule wall that they repel each other. The whole structure expands considerabl...

Pure carbon nanotubes pass first in vivo test

... on methods that will allow nanotubes to circulate longer following injection, so that they can be more easily targeted to specific organs. In another, they are tracking the longer-term behavior and effects of nanotubes in research lab animals. "This research grew out of Smalley’s vision, and he followed...

Recycled paper and compost could both be key tools to control plant disease

...to make new newsprint, and the small fibres are no longer usable, they're a waste by-product. In Britain, about half a million tonnes of these small, unusable fibres are produced each year. They have a potential use in growing media because they hold a lot of water, just like peat and, being a waste produc...

Study shows interruption of antiretroviral therapy increases risk of disease and death

...V is associated with remarkable benefits including longer survival and less illness. However, life-long treatment is difficult and can be associated with both short- and long-term risks, such as major metabolic and cardiovascular complications and built-up resistance to treatment. According to Wafaa El-Sadr...

Vaccine combined with short-term postexposure antibiotics protects monkeys from inhalational anthrax

... few days, some spores can remain dormant for much longer periods, which poses special challenges with regard to postexposure treatment. According to Friedlander, antibiotics are active only after spores have germinated; therefore, dormant spores that germinate after therapy has been discontinued can cause ...

Ghost protein leaves fresh tracks in the cell

...s genetically engineered so that spectrin could no longer bind to ankyrin -- which, Dubreuil assumed, meant that spectrin should no longer attach to the membrane. "We thought that was going to kill the function of the protein," he said, ...

Combination therapy shows promising results in patients with advanced lung cancer

... 93 weeks, Reckamp said, about three to four times longer than the average duration of response for a patient with advanced lung cancer.

Another type of speciation, which many scientists have found harder to imagine, involves animals that live in the same geographic location but, for some reason, begin to mate selectively and form distinct gro...
