... extensivepolysaccharide capsule, an elaborate and dynamic structure surroundingthe cell wall that is unique among fungi that affect humans. TheScience study identified greater than 30 new genes likely involved incapsule biosynthesis, including a family containing 7 members of thecapsule associated (CAP64) g...

Weill Cornell Research Reveals Secrets Of Trafficking Within Cells

... that now we could suddenly look at a much broader dynamic range of activity," Dr. Ryan said. "Instead of it being an 'all or nothing' proposition, we were able to understand how changing different amounts of clathrin changed the speed of endocytosis." "This had literally never been done before, which is on...

Critical role in programmed cell death identified

...eath is induced, " Conradt said. Mitochondria are dynamic structures, constantly changing shape, budding and fusing. In cells instructed to die, the mitochondria tend to become smaller or fragment, but whether this fragmentation is a requirement for cell death or a byproduct has been unclear, until now. Co...

Highly adaptable genome in gut bacterium key to intestinal health

...ortant to understand how gut microbes adapt to the dynamic environment of the gut and ensure the functional stability of the intestinal bioreactor, the researchers say. In addition, variations in the composition of gut microbial communities among different people may be an important factor that influences pr...

First real-time view of developing neurons reveals surprises, say Stanford researchers

...bilized into the mature form. "We're looking at a dynamic process that nobody has ever seen before," Smith said. Understanding how neurons mature into their adult role goes beyond zebra fish and their ability to see their eventual planktonic prey. "Probably these same processes are happening in our own bra...

Love's all in the brain: fMRI study shows strong, lateralized reward, not sex, drive

...the romance. Everyone knows that relationships are dynamic over time, but we are beginning to track what happens in the brain as a love relationship matures." Helen E. Fisher, a research anthropologist at Rutgers University, New Jersey, noted that not only did the brain change as romantic love endured, but ...

A puzzle piece found in unraveling the wiring of the brain

...t proteins were previously known to display highly dynamic expression patterns in both time and space, but how they are put at the right time and at the right place remains to be shown. This study answers part of that question. Others who participated in this work include Dr. Mike Crair of BCM, Drs. R. Grac...

Ancient immune defense mechanism is no match for HIV-1

"Our results suggest that the dynamic interplay between RNAi and SRS remains physiologically conserved from plants and invertebrates to higher vertebrate animals," explains Dr. Jeang. "Our finding that Tat is an SRS also helps explain the long-standing biological observation that when HI...

Leprosy genome tells story of human migrations, French researchers report in Science

...yze. They focused on genetic sequences known to be dynamic -- to move around, copy themselves or disappear -- and thus most likely to reflect evolutionary change, but found strikingly little variation. Next, the researchers looked for mutations known as "single nucleotide polymorphisms" or "SNPs," which are...

Researchers reveal secrets of flying snakes

... while gliding, none are as dramatic, rhythmic and dynamic as the flying snake," Socha said. During his first study, published in Nature in August 2002, Socha described a few aerodynamic features of the paradise tree snake -- one of five snake species that are purported to "fly." He videotaped and photograp...
