The endless possibilities of genetically engineering microbes never cease to amaze me.
"A company called Genomatica, based in San Diego, says that it can make the key ingredient in spandex from sugar, and do so at a cost that competes with current chemical processes, which use fossil fuels. ... Read More
Hands wring and teeth gnash over the loss of endangered species like the panda or the polar bear. But what happens to the parasites hosted by endangered species? And although most people would side with the panda over the parasite, which group should we worry about more?

A mineral found at health food stores could be the key to developing a new line of antibiotics for bacteria that commonly cause diarrhea, tooth decay and, in some severe cases, death.
The trace mineral selenium is found in a number of proteins in both bacterial cells and human cells called se... Read More

New data on the persistence of avian influenza viruses in the environment has allowed a team of University of Georgia researchers to create the first model that takes into account both direct and indirect transmission of the viruses among birds. The model, which is detailed in the early online e... Read More
Germs live everywhere. You can find germs in the air, on food, plants and animals, in the soil, in the water, and on just about every other surface — including your own body.
Most germs won't harm you. Your immune system protects you against a multitude of infectious agents. However, some ger... Read More
This is a novel idea.
"Biologist Donald E. Ingber of Harvard Medical School, his postdoctoral fellow Chong Wing Yung and their colleagues have devised a way to filter pathogens from the blood of septic patients using micron-size magnetic beads. In their model system, beads coated with an anti... Read More
The black salt marsh mosquito, Aedes taerniorhynchus, one of three species found in the Galapagos island, has evolved to drink the blood of reptiles which is now raising alarms in terms of spreading infectious diseases such as West Nile Virus to the mainland of Ecuador.
On the continent Aede... Read More
A new species of a malaria parasite that infects chimpanzees is closely related to a similar parasite Plasmodium falciparum that infects humans, according to research published in PLoS Pathogens.
Why should we care?
"Investigation of the nuclear genome of this new species will further th... Read More
Wanted (soon): observations from environment-minded citizens that will allow science to study biodiversity at a planetary level in a massive, comprehensive virtual observatory of historic importance.
The online information system for life on Earth, now under construction, will take its place ... Read More
Scientists say the symbiotic relationship between algae and corals is breaking down:
"Corals, it appears, have a genetic complexity that rivals that of humans, have sophisticated systems of biological communication that are being stressed by global change, and are only able to survive based o... Read More
Scientists are now be able to gain a reasonably accurate picture of the ocean's health and productivity about every week, all over the planet.
Researchers from Oregon State University, NASA and other organizations said today that they have succeeded for the first time in measuring the physiol... Read More
Julia A. Segre and her colleagues are on an expedition of sorts, collecting information about the diversity of species in an ecosystem.
But Dr. Segre isn’t off trapping insects in the woods somewhere or scooping up samples of plankton on an ocean voyage. The species she and her colleagues ar... Read More
Current tests to identify specific strains of infectious prions, which cause a range of transmissible diseases (such as mad cow) in animals and humans, can take anywhere from six months to a year to yield results – a time-lag that may put human populations at risk.
Now, a group of scientists... Read More
Pregnant women who are deficient in vitamin D may be at increased risk for developing bacterial vaginosis, a vaginal infection that may have harmful effects on the pregnancy, according to a report in The Journal of Nutrition.
Bacterial vaginosis is caused by an imbalance of the bacteria norma... Read More
Vancomycin resistant enterococci (VRE) have been found in sewage sludge, a by-product of waste-water treatment frequently used as a fertilizer. Researchers writing in the open access journal Acta Veterinaria Scandinavica point out the danger of antibiotic resistance genes passing into the human ... Read More
