Learning to fight an adversary that won't stay down

...timicrobials. And they keep coming." However, the mapping of bacterial genomes has not yet helped yield solutions to the problem, says Dr. Davies. He adds that our understanding of the activity of microbes must extend beyond the newspaper headlines reporting outbreaks of these "superbugs," so that we can p...

First 'atlas' of key brain genes could speed research on cancer, neurological diseases

...uman brain as well. “This is the first systematic mapping of all of the major brain areasthat shows what regulatory genes are expressed in those specificlocations,?said Quifu Ma, PhD, of Dana-Farber’s Cancer BiologyDepartment. He is senior author of a paper appearing in today’s onlineissue of the journal Sc...

Papers of DNA Pioneer and Nobel Laureate Francis Crick Added to National Library of Medicine’s Profiles in Science Web Site

...nd biotechnology, such as genetic engineering, the mapping of the human genome, and genetic fingerprinting, all have their origins in Crick’s inspired work,?said Donald A.B. Lindberg, M.D., director of the National Library of Medicine. “The double helix has not only reshaped biology, it has become a cultural...

Measuring the impact of post-genomics on Mediterranean populations

...h. The life sciences ?in particular following the mapping of the human genome ?offer vast opportunities to improve scientific knowledge and approaches to improving human health and welfare. The workshop, organised by the Pasteur Institute in Tunisia earlier this month, set out to explore how discoveries in ...

Researchers discover chemical compounds that affect plant growth

...e components. Combined with the formidable genetic mapping and information available from the Arabidopsis plant, chemical genomics is becoming a powerful new tool in plant biology. It is helping scientists better understand protein transportation and genetic signaling in a plant's cellular membrane system, w...

Computational Method Speeds Mapping of Cell Signaling Networks

...s. But cell signaling networks are so complex that mapping them has been a slow, arduous process. Now, a res...nburger of MIT has "opened the door for systematic mapping of signaling pathways," according to team member Dana Pe'er. They tested their technique--a combined...

Researchers find new genes necessary to make embryo

...s discovery is an important step toward a complete mapping of which parts of the genome are required for embryonic development. The new findings also probe into how genetic networks are built and how they could evolve. The team, headed by biologists at NYU, is studying the genome of the Caenorhabditis elega...

Study: 'homemade' gene expression technology unreliable

...nd cures for a variety of diseases. "Human genome mapping has made the production of these microarrays possible," Spencer said. "Our interest is in how environmental factors ?drugs, pollutants, workplace substances, natural toxins, food chemicals, fragrance raw materials, other factors ?impact or interact w...

Cooperation is key—a new way of looking at MicroRNA and how it controls gene expression

...ey to Control Ever since biologists first started mapping genetic traits to particular genes, science and society have been fascinated by those tens of thousands of stretches of DNA within the nuclei of cells we call our genes. One thing that has become clear in the last several decades, however, is that w...

Brain May Be Less Plastic Than Hoped

...measured electrical activity in the visual cortex; mapping virtually the same cortical quiet zones. The results confirmed the fMRI readings. Smirnakis said it is possible that the visual cortex could reorganize before or after the two- hour to seven-month time frame of his study. Other research has suggeste...

High fidelity keeps human DNA assembly line humming

...discovery on the inner workings of genetic coding, mapping out mechanisms of one of life's most elemental functions: RNA synthesis. Their work has crucial implications for how a normal cell forms a tumor and how a virus runs amok. The work is published in the May 13 edition of the scientific journal Molecul...

Map of life on Earth could be used on Mars

...ion could have lasted for a billion years." After mapping early habitat divergences onto the tree, Blank observes that the ancestors of each of the three kinds of prokaryotes inhabited one of Earth's three types of hydrothermal systems, which include sulfurous steam vents like those which smatter the Yellow...

Scientists discover global pattern of big fish diversity in open oceans

...It really hurts to see this." In the first global mapping of predatory fish diversity in the open ocean, the international team of scientists show where the diversity of the big fish was greatest 50 years ago ?and the dramatic contrast of what remains today. The ocean off Northwest Australia, for example, w...

Novel live reporting system to track cells

...cule in the cell can serve as an advanced tool for mapping gene expression. Future gene therapy may use a technique in which non-invasive magnetic resonance imaging (MRI) is used to track this molecule. The results of this research, conducted by Prof. Michal Neeman of the Weizmann Institute's Biological Regu...
