ASU researchers 'wire' DNA to identify mutations

...to tunnel through, just like lowering a hill for a marathon runner. "The other may be a charge-hopping phenomenon, where the electrons get trapped in the DNA and then hop from the electrode to the DNA to the second electrode." The next goal of the research is to make the measurement steps easier and faster...

Darkness unveils vital metabolic fuel switch between sugar and fat

...als ?a bear foraging for food or a human running a marathon ?also undergo a similar switch, burning glucose first to fuel their efforts, and as blood sugar is consumed, their bodies switch to burning fat. "How does the body know when to switch? 5'-AMP is the signal. I believe it's the same metabolic syste...

Researchers discover how bacteria sense their environments

... distance used in atomic physics that is a virtual marathon in the world of intracellular communication. Ten angstroms equal a nanometer, which is one-billionth of a meter. Sang-Youn Park, a former graduate student in Cornell's Department of Chemistry and Chemical Biology, and senior research associates Pete...

'Exercise pill' switches on gene that tells cells to burn fat

...the genetic metabolic engineering that created the marathon mouse is permanent, turned on before birth. While...netically engineering changes in metabolism in the marathon mice triggers both increased fat burning and increased endurance. Adult normal mice that receive th...

Power-boosting signal in muscle declines with age

...For example, Shulman said, the skeletal muscles of marathon runners typically have much greater mitochondrial content and a greater capacity to burn fat. Those properties can most likely be attributed to chronic activation of the AMPK pathway. "In regards to insulin resistance and type 2 diabetes, having m...

DNA-damage test could aid drug development

In the daunting marathon that leads to successful drugs, promising drug candidates must pass toxicity tests before entering clinical trials. Researchers from Massachusetts Institute of Technology and Whitehead Institute have developed a cell culture test for assessing a comp...
