Shark skin saves naval industry money

...y costs in the naval industry. Shark skin offers a structural design that prevents this so called 'bio-fouling'. Ralph Liedert from the University of Applied Sciences, Bremen, Germany, is presenting his work on the application of artificial shark skin in a new anti-fouling strategy at the Society for Experimen...

Scientists focus on 'dwarf eye'

...a from the RPE. Beneath the RPE are two layers of structural tissue that give the eye its shape. During childhood, these tissues stretch, like a balloon, as the eye grows. "The RPE is believed to be the key link in signaling these tissues to stretch," said Sundin. "And MFRP, located exclusively in the RPE an...

Snapin: A protein with therapy potential for autism

...708 ). Cypin works on tubulin, a protein that is a structural building block of the dendrite skeleton. Now Firestein's research group has turned its attention to the protein snapin. When snapin binds to cypin, tubulin is crowded out, so fewer dendrites assemble and more branching occurs. When researchers overe...

'Punctuated' evolution in the human genome

... scale. Eichler's group performed a comprehensive structural and evolutionary analysis of a 700-kilobase (Kb) pericentromeric region on the short arm of human chromosome 2. This chromosome has intrigued evolutionary and primate biologists for years because it appears to have formed from the fusion of two mid-s...

Spiders help scientists discover how muscles relax

...n filaments during contraction of a muscle. The structural studies were done using tarantula striated muscle, which the team has been studying since the 1980s. Striated muscles from the large, hairy spiders contain filaments that are particularly well ordered, making them easier to study structurally than th...

Major advance made on DNA structure

... is a significant step forward, a milestone in DNA structural biology." In the early 1950s, two researchers at Cambridge University ?James Watson and Francis Crick ?made pioneering discoveries by proposing the double-helix structure of DNA, along with another research group in England about the same time. They...

U of T doctoral candidates Winnie Jeng and Andrea Wong and undergraduate Ryan Ting-A-Kee were also involved in this study. The research was supported by a grant from the Canadian Institutes of Health Research (CIHR). The ...

Malaria mechanism revealed

...o convince him that this was a good project," says structural biologist Leemor Joshua-Tor of Cold Spring Harbor Laboratory, who led the research. A major pathway through which malaria parasites invade red blood cells is the binding of a protein on the surface of merozoites called EBA-175 to a receptor protein ...

Massey Cancer Center researcher helps to identify a piece of the cancer puzzle

A structural biologist from the Virginia Commonwealth University Massey Cancer Center, in collaboration with researchers at Memorial Sloan-Kettering Cancer Center, has identified the crystal structure of a protein that plays a role in supplying nutrients to solid...

U of T researchers map role of Epstein-Barr virus in cancer

...own in culture. Frappier says the paper provides a structural explanation of this protein complex so scientists can see in molecular detail how the EBNA1 protein binds to USP7 and the resulting impact on cell growth. Once that level of detail is achieved, she says scientists can then design specific mutations i...

Chimp genome reveals a retroviral invasion

To further explore the evolutionary history of the retroviral elements, the authors compared the sequences of gag and pol, as well as the LTR sequences, for e...

This month, Carnegie global ecologists and engineers from the NASA Jet Propulsion Laboratory are flying an upgraded version of the AVIRIS airborne spe...

Molecular fossils uncover link between viruses and the immune system

...These results are an outcome of recent advances in structural biology, a new discipline integrating applied physics, biochemistry and biology, which have permitted detailed comparison of viral structures in atomic detail. Such comparison led to the discovery that viruses without any sequence homology may be rel...
