Biotechnology's newest chemical tool

...mpressive list of achievements. It has a complete, fully sensitised five-fingered hand. The CYBERHAND prototype has 16 Degrees of Freedom (DoFs) made possible by the work of six tiny motors. Each of the five fingers is articulated and has one motor dedicated to its joint flexing for autonomous control. I...

Master regulatory gene found that guides fate of blood-producing stem cells

...f all of these genes. What's more, they found that fully assembled NF-Y was activated in stem cells and disappeared when the stem cells became mature cell types, through the induction and loss of one its subunits, NF-Ya. "When we overexpressed NF-Ya in stem cells, the stem cells produced ten- to twenty-fo...

An essential regulator of body weight revealed

...NPY/AgRP neurons are eliminated before they become fully functional, then animals somehow compensated, maintaining feeding behavior though some other mechanism. The compensatory mechanism persists, as animals treated with diphtheria toxin early in life and then again as adults continued to eat normally. ...

'License to kill' enables powerful immune attack cells in mice

...t the arsenals of natural killer cells only become fully armed after a receptor on their surfaces interacts with a molecule on the surfaces of other cells. The molecular details of the process were so unusual that Yokoyama and his colleagues found themselves struggling to develop terms to describe it to o...

A 'dimmer switch' for genes

...also discovered that conventional wisdom failed to fully describe how proteins function. It was known that proteins have regions with parts that are fixed in space, with a definite structure, and parts that are randomly positioned in space, like spaghetti strands. It was thought that the structured regions...

U-M scientists discover identifying markers for primitive blood-forming stem cells

...ietic stem cells, multipotent progenitor cells and fully developed bone marrow cells. They selected genes that were expressed at higher levels in the HSC population, as opposed to the other two types of cells. CD150, the founding member of the SLAM family of cell surface receptors, was near the top of the ...

Tissue regeneration operates differently than expected

...s & Development, August 2005). Stem cells are fully unspecialised cells which can develop into all kinds of cell types. Embryonic stem cells provide the origin of a developing organ, during the growth of an embryo. For example, mesenchymal cells ?stem cells from embryonic connective tissue ?transform ...

Scientists get first glimpse at how plants, most animals repair UV-damaged DNA

...ing the photolyase reaction in the laboratory, and fully understanding it. Zhong hopes his latest study will change that. "Maybe now that we know how light, enzyme, and water work together to control the timing, we can modulate this function and mimic what nature does," he said. "We want to understand why...

The final device will be roughly the size of a human hand, allowing it to be used in doctors' surgeries to determine the genetic predisposition of a patient to certain diseases in a matter of minute...

Fish and chips: A fast track to understanding blood development

...hrough a process called self-renewal. What was not fully understood is which genes control the self-renewal and differentiation processes, and how these genes could be used to influence, or regulate, these processes. The research will be published in the July issue of the journal of Public Library of Scie...

...ding. He said one focus of the research will be to fully develop anti-H3 antibodies in the lab that can be given to humans. "We'll be working to further characterize and develop the use of this antibody as a treatment for smallpox," Dr. Crotty said. The smallpox virus has been the subject of intense rese...

Squeezing out dune plants

...sts, in a low sea-rise scenario, plant communities fully developed over five years, but in cases of moderate and high sea level rise, plant communities were too stressed to grow in many areas, leading to smaller dunes and an eventual breakdown of dune formation. In the higher water scenarios, the plant pop...

Currently, most recommendations for mold remediation call for removal since dead mold retains its ability to trigger allergic reactions, according to Dr. Martyny.
