Boosting The BCG Vaccine To Beat Tuberculosis

... phagosome. The lack of urease C allows phagosomal acidification and provides an ideal pH environment for listeriolysin. The new BCG vaccine strain protects mice against tuberculosis significantly better than the parental BCG. Superior protection is not only induced against the laboratory strain of M. tuberculosi...

Acid water in East Java threatens biodiversity and local welfare

... According to Lohr, one possible solution for the acidification problem is simply to prevent the crater water from mixing with both neutral rivers. She believes that this could be realised by channelling the flow of acidic water from the crater into the sea, which with its enormous water surface would not suffer ...

Oceans turning to acid from rise in CO2

...logy in Stanford, California.* The report on ocean acidification was released today by the Royal Society. See http:... food chain. "We can predict the magnitude of the acidification based on the evidence that has been collected from the ocean's surface, the geological and historica...

Dangerous tricksters: Some bacterie use immune cells to reproduce

...some development inside the macrophage, preventing acidification and merging with the lysosomes. As a result the bacteria are not exposed to the large array of lysosomal digestive enzymes and acid. Killing the killer 'Basically what this means is that the rhodococci manipulate their host cell, they make it the...

Ocean acidification threatens cold-water coral ecosystems

...t, bottom trawlers smash them to bits. Then, ocean acidification will probably slow the skeletal growth and/or lead to weaker skeletons of those that remain. Ocean acidification will likely have serious and wide-reaching impacts, not only for coral ecosystems but for all life i...

Volcanic eruptions, ancient global warming linked

... "planetary emergency" ?also greatly increased the acidification of the world’s oceans and led to the extinction of numerous deep-sea species. Warming periods in Earth’s history are of interest as analogs to today’s climate change, Duncan said. The international science team was able to link the PETM with th...

Gene chips forecast ecological impacts of climate change

...use gas, carbon dioxide, the predictions for ocean acidification are more problematic than temperature stress alone. Data presented will show how gene chips and other molecular approaches can assist in understanding how marine invertebrates are responding to the climate-change related multiple stressors in the wor...

Are we killing the world's oceans?

...will speak on such issues as climate change, ocean acidification and coral reefs, the increase in ocean dead zones, scientific and social dynamics during fisheries crises, how we all play a role in the collapse of coastal fisheries, and environmental issues surrounding offshore petroleum resource development. Ther...

Scientists uncover link between ocean's chemical processes and microscopic floating plants

...have not even begun to think about, effects beyond acidification of surface seawater and greenhouse warming," said ...that we understand the outcome of increasing ocean acidification and increasing carbon dioxide levels." ...
