Genome changes tracked during multiple myeloma initiation, progression and treatment

...different cancers. "This integrated and detailed view of the MM genome is consistent with the concept of widespread changes in the expression of genes with cancer activity in the pathogenesis of MM, a concept with therapeutic and diagnostic implication for MM in particular and cancer in general," explai...

Virginia Bioinformatics Institutes launches microbial database

...reated a browser, which makes it easy for users to view the genome sequence data and connect to detailed annotation pages for each sequence. The community annotation interface is available for registered members to add or edit annotations. The database will be expanded in 2006 to include genome sequence...

Alzheimer's found to be mostly genetic

...dy. The study raises doubts about the widely held view that Alzheimer's has two forms: the "familial," with genetic roots, and the "sporadic," with environmental causes. "In essence what we're doing is taking the folks who would have formerly been called sporadic, and testing how important genetic influ...

Research could lead to better drugs and whiter whites

...dings are a radical departure from the traditional view of how they work and might explain why attempts to make artificial enzymes have so far been disappointing. The work ?published as a major research article in the leading journal Science ?builds on earlier studies by Professor Scrutton and Manchester...

U of MN researchers develop way to visualize synchronized interactions of nerve cells in the brain

...ecorded from each sensor was analyzed over time to view how large groups of active brain cells operate and interact simultaneously with each other in different parts of the brain. ...

Thin tough skin, slow-growing gills protect larval Antarctic fish

...ins must be present from the time of hatching -- a view held by scientists since fish AFPs were found in the 1960s. Internal fluids such as blood in many notothenioids are about half as salty as seawater. While seawater reaches its freezing point at -1.91 degrees Celsius, fish fluids will freeze at about...

Protein 'nanosprings' most resilient found in nature

...hers said. Using atomic force microscopy (AFM) to view individual molecules in the current study, Marszalek and Pratt research associate Yong Jiang found that ankyrin repeats indeed display a hook-like shape consistent with a spring. AFM is a technique for analyzing the surface of materials all the way d...

Earth Rx: A microbial biotechnology prescription for global environmental health

These technologies have advanced into high-throughput genomic and proteomic protocols that can detect specific genes and their metabolic functions with great precision and detail. Other me...

Hooked on fishing, and we're heading for the bottom, says scientist

...ues is distorted by the fact that most governments view fishing companies, and not their citizens, who actually are the true owners of the resources, as their main constituency. While the situation is dire, Dr. Pauly believes this situation can be turned around. He believes that a reduction of excess fis...

Ernst Mayr's theory illustrated in genetic epidemiology studies

... the single gene itself. His, Wright's and Mayr's view is that major and minor are properties of an interactive genetic system, and, depending on the frequencies of the interacting factors, some genes seem to play a larger role than others at any given time. "The real causation of the trait is at the in...

Mute swan population helps explain longstanding evolutionary question

...ly the debate switched to an evolutionary point of view with a second, related question: Why is clutch size not evolving despite significant heritability and directional selection?" Many long-term studies of avian clutch size have looked for--but not seen-- an increase in the number of eggs laid. However...

Hyena mothers give their cubs a helpful dose of hormones

Genes involved in cell growth and cell division identified

... cancer, it is highly important to have a holistic view on these processes. This study belongs to the emerging field of systems biology, which aims to a comprehensive understanding of cellular mechanisms by carrying out large-scale experiments and combining the data using bioinformatics. The screening ...

Vaccine provides 100 percent protection against avian flu virus in animal study

..., we are starting to get a truly paradigm-shifting view of all life on the planet." A better understanding of these microbial communities and how their genes allow them to interact with the environment underpins the larger study of biology. "The open ocean is Earth's largest and, perhaps, most complex ec...

If the probes prove beneficial in human testing, the advance might lead to more precise and safer endoscopic surgeries, said the Duke engineers. Th...

Study finds that nutritionally enhanced rice reduces iron deficiency

... density in rice to be even more effective. "We view this study as a 'proof of concept,'" said Zeigler. "We now know that, if plants are bred with higher levels of iron and other micronutrients, they will improve the nutritional status of people who consume them. This has dramatic implications." Thr...

Drunken elephants: The marula fruit myth

...d Biochemical Zoology. "The tipsy pachyderm [is] a view bolstered perhaps by a mutual desire for the fruits of the marula tree." Based on reports of elephants accessing stores of wine or beer, the three-ton mammals clearly have a taste for alcohol. They also have a demonstrated fondness for marula fruit,...
