'Executive' monkeys influenced by other executives, not subordinates

...o the screen, randomly in the direction the monkey image was looking or in the opposite direction. The monkeys were given juice rewards for their participation in each trial. After a large number of trials, the researchers statistically analyzed whether status played a role in the monkeys' tendency to fol...

MIT: Oceans are a major gene swap-meet for plankton

...nes. In essence, what all this means is that "our image of ocean microbes and their role in planetary maintenance is changing," Chisholm said. "We no longer think of the microbial community as being made up of species that have a fixed genetic makeup. Rather, it is a collection of genes, some of which are...

Scientists discover interplay between genes and viruses in tiny ocean plankton

Fruit fly's beating heart helps identify human heart disease genes

... fruit flies because of an inability to accurately image heart function of a living adult fly. Past investigators have measured the size of the heart and then made assumptions about what was happening inside, or dissected flies after death. For their experiments, the Duke team adapted a technology known a...

Rochester scientists develop fast-working biosensor

...a alters the surface of the chip. A digital camera image of the chip captures the changes for analysis and confirmation of detection. Traditional methods of detection of bacteria can take days. "This takes as much time as it takes for a snapshot," Miller said. The scientists currently are defining the se...

T-rays: New imaging technology spotlighted by American Chemical Society

...rgy in the THz range that can be used to sense and image objects. A particular advantage of T-ray systems is that they can also give spectroscopic information about the composition of chemical and biological material, and are safer for biological applications than X-ray photons, that emit a million times m...

Researchers use 'trickery' to create immune response against melanoma

...rs also used high magnification microscopy and 3-D image reconstruction to study the localisation of the bioconjugates after incubation with the prostate cancer cells and confirmed that the particles were rapidly internalised into the targeted cells ?an important fact since the payload of nanoparticles may...

Picture, if you will, a mangled quarterback's occipital bone banging the ground, then rebounding. The researchers have mimicked that very motion with humans on a far milder, gen...

Image of myosin-actin interaction revealed in cover story of Molecular Cell

...s study required a different way of thinking about image analysis. This is the first time we were able to structurally visualize the weak binding states of actin and myosin, not interpolated from crystal structures, and not interpolated from biophysical methods," said Dr. Hanein. "We were able to see struc...
