Like a smart highlighter, immunofluorescent labeling can zero in on a specific protein, helping scientists understand the structure of a cell and how diseases affect that structure. Current techniques have disadvantages, ...
Using an extremely sensitive measurement technique, researchers at the University of Illinois have found clear evidence that a lead-specific DNAzyme uses the “lock and key” reaction mechanism. In the presence of zinc ...
Researchers have shown how tiny "nanorods" of gold can be triggered by a laser beam to blast holes in the membranes of tumor cells, setting in motion a complex biochemical mechanism that leads to a tumor cell's self-destruction.
Scientists studying biological systems at the molecular level now have a new hybrid technique to probe the dynamics of the Holliday junction. The Holliday junction is a four-stranded DNA structure that forms during a process ...
Researchers in California are reporting development of a fast, inexpensive test suitable for home use that could help millions of people avoid those ‘out of the blue’ headaches that may follow consumption of certain red ...
Layer-by-layer light microscopic nanoscale images of cells and without having to prepare thin sections? A team led by Stefan Hell and Mariano Bossi at the Max Planck Institute for Biophysical Chemistry in Göttingen is now ...
Applying physical stress to cells, researchers at the University of Pennsylvania have demonstrated that everyday forces can alter the structure of proteins tucked within cells, unfold them and expose new targets in the fight ...
Ultrasensitive genetic detection methods could revolutionize the diagnosis and treatment of diseases. However, all the techniques until now have been far too technically demanding for broad application. Munich researchers ...
A chemist at Washington University in St. Louis is making molecules the new-fashioned way — selectively harnessing thousands of minuscule electrodes on a tiny computer chip that do chemical reactions and yield molecules ...
Parting a tiny red sea at the University of Cincinnati: Today’s — and tomorrow’s — sophisticated electronic devices may hinge on our ability to control microdrops of liquid on a surface. This effect, called electrowetting, ...
