Marathon of nano-sprinters

...trong tendency to fall off their track and diffuse away into the surrounding aqueous solution. This is a direct consequence of their nanoscale size which makes them rather susceptible to thermal noise. Thus, a single molecular motor can only 'grab' onto the filament for a relatively short time, on the ord...

Plant defenses prompt bacterial countermeasure in the form of 'island' DNA excision

...o be identified. If some bacterial proteins give away the presence of the pathogen to the plant, why are they and their surrounding genomic islands maintained by the bacteria at all? There are many genes included in the genomic island that is excised by the halo-bright strains studied here, and these ot...

Scientists use stem cells to grow cartilage

... head and neck cancers, surgeons often have to cut away parts of cartilage, and then take grafts from other parts of the body. With this new technique doctors would potentially be able to take stem cells from the patient, grow them in a laboratory, and then transplant them after the surgery. This work bu...

... of other sea life, such as sharks, who would pick away at carcasses for food. Because of their mostly shallow sea and seaside habitats, the remains of early mosasaurs are even more rare and much harder to find. But in the last two decades, many new discoveries and significant advances have been made in ...

Clinical trial to test stem cell approach for children with brain injury

...lies and on society," Cox said. Trauma is far and away the main cause of death and disability among children, and the main reason children die from trauma is brain injury, Cox said. The proposal was under review for a year. The U.S. Food and Drug Administration approved Cox's Investigational New Drug (I...

Membrane research opens window to benefits for plants, humans

...clearly showed that specific residues that sit far away from a water pore control the opening of the channel, said biophysics professor Emad Tajkhorshid (pronounced uh-MOD tazh-CORE-shid). The residues, they found, latch onto an intracellular loop of the protein, blocking the water channel when not phosp...

Brain activity related to processing faces is similar in people with, without autism

...e individuals with autism typically choose to look away from faces, the previous studies could not disentangle the effects of a preference to look away from faces from actual brain deficits in the ability to process faces. "We required participants to ...

Polymer gel can block toxic leakage problem in gene therapy

...eutic gene-bearing viruses were being disseminated away from the tumor site via the blood stream, Yuan said. "In the past people wouldn't admit that," he said. "Nobody in the gene therapy field would believe this was happening." The study also pinpointed the routes for the viral escapes. Those particles ...

Removing egg from nest may help save endangered whooping crane

Only wolves were completely eliminated from the study area and subsequently recovered. Be...

Grabbing addiction by the tail
