"Increasingly, our discipline is faced with deciphering the structure of large, complex proteins in which some parts are constantly moving, even when the protein is locked in a...Catching cancer's spread by watching hemoglobin
...laser beams across the sample, a process that then reveals the outlines and contours of blood vessels. By taking images at different depths and stacking these images layer by layer, the researchers can reconstruct 3-D images of blood vessels. A major advantage of the technique is that it is "label-free,"......sofia Viranyi, of the Etvs University in Budapest, reveals striking similarities between humans and dogs in t...rst time that animals do imitate selectively.

.... A new study at Mount Sinai School of Medicine reveals that AGE levels are elevated in the blood of healthy people, and even more so in older individuals than in younger people. Of particular interest was the finding that a major determinant of the blood levels of AGEs is the amount of AGEs in the diet,...Spousal choices can influence the risk of developing alcoholism

Their study, published in Nature, reveals that during early embryonic development, cilia point more or less in the general direction of the body's back end and start creating a weak flow. During the following refinement phase, all cilia get in line and trim their sails to the prevailing wind...UCLA/Toronto researchers unlock key to memory storage in brain
...cage, the scientists tracked a genetic marker that reveals recent neuron activity. When the team examined the animals' amygdalas after the experiment, they found substantial amounts of CREB and the marker in neurons. "We discovered that the amount of CREB influences whether or not the brain stores a memor...Scientists unlock secret of what makes plants flower
The study reveals the likely mechanism by which the Arabidopsis plant flowers in response to changes in day length. Earlier research had shown that plants' leaves perceived seasonal changes in day length, which triggers a long-distance signal to travel through the pla...First systematic study of China's one-child policy reveals complexity, effectiveness
