Supersized 'island' of resistance genes discovered in an infectious bacterium

...s that escaped the scrutiny of the large number of laboratories already working on multi-drug resistant A. baumannii throughout the world. This is a demonstration of the efficiency of the whole genome approach in characterizing new pathogens," said Jean-Michel Claverie, senior author of the report and Director o...

Report finds cruise industry is protecting the precious places it visits

...o. Several cruise lines have installed scientific laboratories on its ships to help scientists conduct research on vital marine and climate issues. The Government of Belize established a small visitor tax to generate sustainable financing that supports the management of the country's parks and protected areas....

Access to antiretrovirals unlikely to reduce HIV infection rates

...he strategies included the provision of diagnostic laboratories that could routinely measure CD4 counts and viral loads of HIV-infected individuals (only if this is done could people be treated before they develop overt symptoms). They also took into account different ways that people might change their sexual be...

MIT research holds promise for Huntington's treatment

...The compound developed by Bodner and others in the laboratories of MIT Professor of Biology David Housman, Harvard Medical School Assistant Professor Aleksey Kazantsev and Harvard Medical School Professor Bradley Hyman might lead to a drug that could help stop the deadly sequence of cellular events that Huntingto...

Common molecular 'signature' identified in solid tumors

... for normal development. Since then, scientists in laboratories around the world have identified hundreds of miRNAs and found that they are highly conserved over time ?meaning that they show up in generation after generation in everything from plants to mice to humans ?confirming their important roles in growth a...

Avian flu modeled on supercomputer, explores vaccine and isolation options for thwarting a pandemic

...e virtual dice. "Computer models serve as virtual laboratories where researchers can study how infectious diseases might spread and what intervention strategies may lessen the impact of a real outbreak," said Jeremy M. Berg, director of the National Institute of General Medical Sciences. "This new work exemplifi...

Technique speeds up detecting, treating wound bacteria

...be 12 or more organisms present, and most clinical laboratories are not proficient in isolating and identifying anaerobes, which often predominate." Using DNA detection methods though a technique called real-time polymerase chain reaction, the physician-researcher from the West Los Angeles Veterans Administrati...

Parasitic worms used to fight bowel disease

...Waterborne Diseases Integrated Research Network of laboratories launched by the National Institutes of Allergy and Infectious Diseases. Some researchers argue that improved hygiene throughout the developed world may be responsible for inflammatory bowel disease, as well as a whole range of autoimmune disorders....

Mitochondrial DNA sequencing tool updated

... of the variations. The Affymatrix chip enabled laboratories to resequence the mitochondrial genome much faster...hip served as the broad technological platform for laboratories to customize arrays more attuned to their research interests. In 2004, Dr. Anirban Maitra and his ...

Stanford doctors advance in bid to turn mice stem cells into blood vessels

...dardized process for differentiating stem cells in laboratories that could be used around the world. "The idea behind it is that you can control various conditions to try to make these stem cells become the cells you want," Abilez said. "Our goal is to take the mouse stem cells and find the conditions that will ...

Study supports 'urgent' need for worldwide ban on lead-based paint

...k, left to dry and then removed and analyzed in UC laboratories for lead content. About 50 percent of the paint sold in China, India and Malaysia--none of which appear to have regulations on lead--had lead levels 30 times higher than U.S. regulations. In contrast in Singapore, which has well-enforced regulatio...

Mapping the protein world

...comes at a perfect time. "More than 1,000 research laboratories from over 50 countries are holding ARP/wARP licenses and by June this year our paper that described the key innovative feature of ARP/wARP in Nature Structural Biology in 1999 has reached the magic number of 1,000 citations in the scientific literatu...

UCSD researchers develop 'smart petri dish'

...evice builds on a previous development in the UCSD laboratories of Sailor and Bhatia that allowed the scientists to maintain fully functioning liver cells in culture. While many cell types can be easily grown in culture dishes, normal liver cells are much more discriminating and quickly die when removed from the ...

Methane-belching bugs inspire a new theory of the origin of life on Earth

Two laboratories at Penn State set out to show how an obscure undersea microbe metabolizes carbon monoxide into methane and vinegar. What they found was not merely a previously unknown biochemical process--their discovery also became the inspiration for a fundamenta...

What controls stickiness of 'smart' chromosomal glue

...rch published in two complementary papers from the laboratories of Kim Nasmyth and Yoshinori, which also appeared in Nature, demonstrated that cohesins can be retained at the centromeres during meiosis by enzymes that remove phosphates from the cohesins, counteracting the effects of phosphorylation. Amon and ...

Eminent inventor of DNA fingerprinting gains new recognition

...e Department of Genetics is accommodated in modern laboratories provided with all the facilities necessary for fundamental research and training in genetics. It is one of the largest Departments of Genetics in the United Kingdom and was rated at a Grade 5* in the 2001 national research assessment exercise. It has...

Ghost protein leaves fresh tracks in the cell

...geting spectrin in all cells. But research in many laboratories had failed to find a cue for targeting that acted through ankyrin, so Dubreuil reworked his hypothesis. "We decided to throw out our assumptions and start fresh," he said. A laboratory fly was genetically engineered so that spectrin could no long...

Most widely used organic pesticide requires help to kill

... plant pathology. The new work, conducted in the laboratories of Handelsman and Kenneth F. Raffa, a professor in the UW-Madison department of entomology, demonstrates that Bt requires the presence of other bacteria to exert its lethal influence. Virtually all animals, including humans, depend on the interplay...

Hard-wiring the fruit fly's visual system

...ogaster, the most common form of fruit fly used in laboratories around the world. "There is a genetic component (to formation of the vertebrate visual system)," said Bellen, who is also a Howard Hughes Medical Institute investigator. "The neurons in vertebrates are born and are genetically programmed to project...

Getting to the heart of the heart

...age caused by heart attacks in adults. The two laboratories are now trying to determine the relationship between the two types of progenitor cells discovered. Both papers will appear in the December 15 issue of the journal Cell, which was published online November 22. The Children's team, led by senior inve...
