Researchers examine carbon capture and storage to combat global warming

...ble energy are already feasible today and also can define the long-term energy picture, he said. ''[Carbon dioxide] sequestration, on the other hand, is only a bridge technology,'' he added. ''Maybe we have another hundred years of using fossil fuels, and then we'll be on to better and smarter things, on...

Focused ultrasound relieves fibroid symptoms in women

... received pre-treatment MR imaging to identify and define the target fibroids. Radiologists then used MRgFUS to locate and treat the targeted fibroids while monitoring temperature changes in tissue. Ninety-six patients were treated under the original study protocol (A), and 64 patients were treated und...

The researchers hope to fully define the protein components of the compass to gain a better understanding of what directs cell migration or, in the case of cancer cells and inflammation, cause cells to migrate where they normally wouldn’t. "The ability to spatially organize specific...

"The ability to precisely define and manipulate the nature of the checkpoint activating structure in an experimental system will enable us to control, quantitative and probe checkpoint signaling responses in unprecedented ways." Using Xenopus egg extracts as a cell-free system, t...

The finding may help define the role of cancer stem cells in the growth and recurrence of the disease as well as offer new options for cancer prevention, detection and treatment. Current cancer stem cell theory holds that tumors are comprised of a variety of cell types. Among...

UCLA/Toronto researchers unlock key to memory storage in brain

... in dying regions of the brain." Our memories define who we are, so learning how the brain stores memory is fundamental to understanding what it is to be human, Silva observed. "A memory is not a static snapshot," he said. "Memories serve a purpose. They are about acquiring information that helps ...

Killing the messenger RNA -- But which one?

...nucleotides ?out of a total of only 19 or 21 ?that define the molecule’s target specificity. This suggested that the change might well redirect these edited microRNAs to silence entirely different sets of genes from the unedited versions."
