Double triumph in stem cell quest
...nique, but other teams glue cells to a surface and spin
them until the denser nucleus is forced out. Then the team take cells from adults and fuse them with the enucleated ESCs. The idea is that the cytoplasm of an enucleated ESC will reprogram the donor nuclei, turning the fused cell into an ESC too. Th...
New plant DNA libraries provides massive boost to world's plant researchers
...source. The Warwick researchers have set up a new spin
out company "Warwick Plant Genomic Libraries Limited" to develop this powerful new resource for plant researchers. It will be of particular benefit to academic researchers, scientists working in agriculture and horticulture and also to pharmaceutical...
Research Permits First-Ever Visualization of Psychological Stress in the Human Brain
...The fMRI technique employed in our study ?arterial spin
labeling ?can measure cerebral flood-flow directly,?states John A. Detre, MD, Associate Professor of Neurology and Radiology, and senior author of the study. “This technique is very similar to PET (positron emission tomography) scanning, except that ...

Surprise finding for stretched DNA
...ttached to the DNA to serve as a "rotor" that will spin
in response to torque. Magnets are used to manipulate the magnetized bead, providing a measured and highly controlled amount of tension to stretch the DNA molecule. With the use of a fluorescent coating, the subsequent spinning of the rotor bead in ...

resonance dipolar spectroscopy. The researchers suggest that when one receptor detects, for example, a sugar in its environment, communication of some sort triggers an array of linked receptors to rearrange itself, much like when water freezes, al...
