World's largest rainforest drying experiment completes first phase

Scientists with The Woods Hole Research Center are analyzing the surprising results of the first phase of a drydown experiment occurring in the Amazonian rainforest. . From January 2000 to July 2004, rainfall was excluded from a one-hectare (2.2 acre) plot in the middle of the Tapajós National Forest, in Brazil. A total of 6 feet of rainfall was diverted with six thousand 2' by 6' clear plastic p...

GeneNotes - A novel information management software for biologists

Analyzing microarray data - or even a simple biological network - can get you lost - quick. Tons of genes, tons of synonyms for each, tons of known interactions, with even more being unknown, tons of database with tons of information... and your job is to make sense of this puzzle in a biologically meaningfull way. Applications are being developped to make it all easier, leaving the fun part : b...

Agilent Technologies releases probe sequence, annotation information for all its commercial gene expression microarrays

PHACCS, an online tool for estimating the structure and diversity of uncultured viral communities using metagenomic information

In the March 3 issue of Nature, Johns Hopkins researchers report that two proteins best known for very different activities actually come together to turn the liver into a sugar-producing factory when food is scarce. Because the liver's production of sugar is a damaging problem in people with diabetes, the proteins' interaction might be a target for future drugs to fight the disease, the research...

Bioinformatics reveals new gene regulation system

By comparing 140 sequenced bacterial genomes, researchers have uncovered a system for regulating genes essential to bacterial replication ?and they did it solely by computer keystrokes and mouse clicks. .. Mikhail Gelfand, a Howard Hughes Medical Institute international research scholar at the Institute for Information Transmission Problems (IITP) in Moscow, and his postdoctoral fellow, Dmitry Ro...

Woods Hole Research Center plans controlled burn in Amazon rainforest

Fire is an important agent of transformation in the Amazon landscape. Every year, low intensity fires burn thousands of square miles of Amazon forest. To study the effects of these fires on the forest, and the forests' ability to recover from repeated burning, Woods Hole Research Center scientists will burn two and a half square kilometers of forest in the transition forest of northern Mato Gross...

New bioinformatics technique for systematically analyzing key regions in DNA that help control gene activity

Scientists at Lawrence Livermore National Laboratory (LLNL) and the Linnaeus Centre for Bioinformatics (LCB) at Uppsala University in Sweden have developed a new bioinformatics technique for systematically analyzing key regions in DNA that help control gene activity. The cooperative efforts were headed by Krzysztof Fidelis in the United States and by Jan Komorowski in Sweden. . Understanding the...

Ants, not evil spirits, create devil's gardens in the Amazon rainforest, study finds

For the first time, scientists have identified an ant species that produces its own natural herbicide to poison unwanted plants. . .. "Devil's gardens are large stands of trees in the...

European Commission funds EBI to do new research on synergies between bioinformatics and medical informatics

In findings with implications for pandemic influenza, a new study reports for the first time that a less-virulent strain of avian influenza virus can spread from poultry to humans. The research appears in the October 1 issue of The Journal of Infectious Diseases, now available online. . Crossing the species barrier is an important step in the development of a flu virus with pandemic potential. P...

NIEHS launches website with information for assessing environmental hazards from Hurricane Katrina

A new website with a Global Information System will provide valuable information for assessing environmental hazards caused by Hurricane Katrina. The National Institute of Environmental Health Sciences (NIEHS), one of the National Institutes of Health, created the website to provide the most up-to-date data to public health and safety workers on contaminants in flood waters, infrastructure and in...

Scientists fetch useful information from dog genome publications

Today a plethora of dog genome-related materials are published, including a new book entitled . "Canine genetics has entered a period of unprecedented growth and discovery," explain Drs. Elaine Ostrander and Francis Galibert in their Foreword...

Why the Amazon rainforest is so rich in species

Tropical areas of south and central America such as the Amazon rainforest are home to some 7500 species of butterfly compared with only around 65 species in Britain. UCL scientists have ruled out the common theory that attributed this richness of wildlife to climate change, in a paper published on 7th December by the journal Proceedings of the Royal Society B (Biological Sciences). . Instead, sc...

Infants can organise visual information at just four months

Research investigating attention in infancy has revealed that, at just four months old, babies are able to organise visual information in at least three different ways, according to brightness, shape, and how close the visual elements are together (proximity). These new findings mean that very young infants are much more capable of organising their visual world than psychologists had previously t...

The Amazon in 2050: Implementing the law could save a million square kilometers of rainforest

Economic and political forces are rapidly transforming the forests of the Amazon basin, precipitating one of the world's greatest environmental crises. . Through an inter-discplinary modeling project known as Amazon Scenarios, scientists at the Woods Hole Research Center, the Universidade Federal de Minas Gerais (Brazil), and the Instituto de Pesquisa Ambiental da Amazônia (Brazil), with colleagu...

Amazon rainforest greens up in the dry season

The Amazon rainforest puts on its biggest growth spurt during the dry season, according to new research. The finding surprised the researchers. . .. "What we found for a large section of the Amazon is the opposite. As soon as the rains stop and you start to enter a dry...

Virginia Bioinformatics Institutes launches microbial database

Researchers at the Virginia Bioinformatics Institute at Virginia Tech have launched a publicly-available microbial database to host a range of microbial genome sequences. . The VBI Microbial Database (VMD), which is described in a recent article published in Nucleic Acids Research (Vol.34, D379-D381), contains genome sequence and annotation data for the plant pathogens Phytophthora sojae and Phyt...

Researchers add crucial information on how the body's T cells react to parasitic diseases

In the 1980s, the phrase "T cell count" burst into the world's medical vocabulary as thousands and then millions of patients died of AIDS. The public began to understand the crucial importance of T cells--cellular Pac-Men that roam the bloodstream gobbling up infection and guarding against future attacks. . While scientists understood how T cells worked in certain kinds of diseases, one area has...

The vicious cycle of rainforest destruction

Rainforests and savannas contain 70% of the world's plants and are critical to the health of our planet. A new £1.6m international project involving researchers from the Leeds Earth and Biosphere Institute is looking at the impact of global warming on these sensitive areas. . .. Heading the work at Leeds is Professor of Earth System Sc...

Genome info from 'plant destroyers' could save trees, beans and chocolate

An international team of scientists has published the first two genome sequences from a destructive group of plant pathogens called Phytophthora--a name that literally means "plant destroyer." The more than 80 species of fungus-like Phytophthora (pronounced "fy-TOFF-thor-uh") attack a broad range of plants and together cost the agriculture, forestry and nursery industries hundreds of billions of...

Pacific Rim researchers to collaborate on distributed bioinformatics analysis of avian flu

Researchers at the University of California, San Diego and the University of Hawaii will use bioinformatics, grid computing and networking infrastructure, as well as collaborative ties to Asian institutions to learn more about avian flu, in hopes of helping to head off a much-feared pandemic in the region of the world where the disease has already cost human lives. . "We will use modern high-t...

Speeding 'fingertip' discovery -- 20 years of protein info in 1 place
