BioMed Central launches Biology Direct

...er attended a scientific conference worth its salt knows that the discussions can be quite vigorous, often enough going to bare knuckles, especially during the coffee breaks or at the bar, but also in the conference room itself. Sometimes someone gets upset or offended but it is, definitely, an exception. ...

Patterns in genome organization may partially explain how microbial cells work

...sically distinct coils inside the cell, but nobody knows for certain," Allen said. "One of the take-home messages of our study is that we need to develop more ways to measure the location of specific genes within individual cells." Palsson's team included Allen, recent Ph.D. graduate Nathan D. Price, and P...

Fat chance of becoming manic-depressive

...bed for the treatment bipolar disorder, yet no one knows for sure why it works. "Lithium has a number of severe side effects that include tremor and weight gain. Kidney dysfunction may develop in a small proportion of patients when it is administered for long periods of time," says Professor Mitchell. Th...

In bacterial diversity, Amazon is a 'desert'; Desert is an 'Amazon'

...wing in. It does make sense, since every biologist knows that when you culture microorganisms in the laboratory, the diversity and the health of those organisms tends to decrease in more extreme pHs." However, Jackson did not rule out the possibility of microbial "hot spots" that their broad survey might h...

Unified physics theory explains animals' running, flying and swimming

...s swimming that stumped us," Bejan said. "Everyone knows that, in water, fish are weightless." In other words, they explained, fish are neutrally buoyant, or nearly so, meaning that their tendency to float counteracts the force of gravity and they do not sink or rise. In essence, then, scientists have cons...

Pall blood filtration technology removes prions that can cause TSEs

...vCJD can be asymptomatic for many years and no one knows how many transfusion recipients may be receiving infected blood. There is no reliable test available to determine the presence of vCJD in blood. This past month, the British Department of Health announced that it must track down another 50 people w...

Chlamydia parasite lives off our fat

... cases a year. Chlamydia gets around because it knows its hosts so well. It's an "obligate intracellular parasite" which means that it relies on its eukaryotic host for everything from reproduction to synthesizing ATP, all while living inside a membrane-bounded vacuole that provides a protected, fertile...

Purdue biologists clarify how a cellular 'spacecraft' opens its airlock

...does seem compelling based on what science already knows about the workings of membrane proteins. "We need to look closer at our information and try to find out more," Davidson said. "We will be applying several tests to our data in the near future to determine if our image of these proteins accurately des...

MUHC ensures blood without bugs

... increased by 270% over the past decade. Dr. Ndao knows that every blood sample he tests could represent another life saved--the new blood safety test under development represents a way to provide the expertise of the NRCP to the world. With funding from Health Canada (NML/PHAC) and the Canadian Institute...

Ted Estess, dean of the UH Honors College, knows Halawi through his numerous extracurricular activities and said that the many honors and scholarships that Halawi has been awarded have always been well earned by his hard work, self-motivation and ambitious determination. "We are excited to have M...

Alaska avian flu project issues initial surveillance results

... viruses in wild birds, not just H5N1 -- everybody knows birds are where these viruses come from but no one knows how they get from birds to humans," said George Happ, director of the IDeA Network for Biomedical Re...

Wnt signaling controls the fate of stem cells in adult brains

...n neurogenesis in the exact same areas, but no one knows why the brain would allow new neurons to be born throughout life on in these restricted areas," says Gage. "Finally, with this knowledge of how neurogenesis occurs, we have a tool to block neurogenesis in vivo and find out what its function is," he a...

Researchers find gland that tells fruit flies when to stop growing

...es the second part of the picture how an organism knows that growth should stop. "There has to be a way for an animal to assess its size, and I don't think it does it by looking in the mirror," Riddiford said. ...

Selective logging causes widespread destruction of Brazil's Amazon rainforest, study finds

...orest," Asner says. "Mahogany is the one everybody knows about, but in the Amazon, there are at least 35 marketable hardwood species, and the damage that occurs from taking out just a few trees at a time is enormous. On average, for every tree removed, up to 30 more can be severely damaged by the timber ha...

MSU entomologist appointed to unravel mysterious tropical disease

...t's called the 'mysterious disease' because nobody knows how it's transmitted," Merritt said. "So that's the real dilemma and we're just getting started trying to figure this disease out." Scientists do know Buruli ulcer disease is cased by a bacterium, Mycobacterium ulcerans, found in tropical regions su...

New book highlights world's borderless conservation areas

Frog peptides block HIV in lab study

...re an exceptional tool for probing "what the virus knows about the dendritic cell that we don't know," Unutmaz added. "How does HIV manage to survive and cycle back and forth to the cell membrane? If we can understand that, we'll find the gaps, and that will open a whole new universe of targets for interve...

Cancer drug might help kids with fatal 'aging' syndrome

...ldren," she says. Michaelis emphasizes that no one knows whether making the cells' nuclei look normal will be enough to reverse the disease process or slow it down. "If it does, this will be a wonderful example of how understanding basic biology can lead to new medical treatments," she says. The class of d...

A novel method to measure circadian cycles

Everyone knows morning people and late-night owls. The variation in individual circadian rhythms is an anecdotal as well as experimentally verified fact. But, until now, to systematically study circadian differences (and thereby hope to rout out the underlying gen...

Emerald Spectre haunts Ontario's ash forests

...Chicago. If containment isn't effective, MacIsaac knows well what the future will look like. He arrived at his Windsor-area home one day in the summer of 2003 to see a neighbour cutting down 25 ash trees, among the borer's first victims. In Michigan's Wayne County, the first area infected, 60 per cent of ...
