From Scientist Live, obviously from the name this is a very small bacteria taken from filtered water. The interesting bit is that it is related to water-living bacteria and this is where genes for metal tolerance and antibody resistance come from.
From Physorg.com, so a Macquarie University scientist has cultured bacteria in mud. To which most people would say, “Who cares.” Most bacteria that is cultured using agar. But that only works for a infantesmal portion of the earth’s bacteria. So any new techneques that make studying these microorganisms easier is good news.
Excuse the title. The Science at NASA has been looking at the problem of micro-organisms in enclosed environments, such as the space station, since MIR. It not only involves organisms that cause illness, but organism that have the potential of causing mechanical failures. Also it looks at some new technology that I’ve been intrigued with, the lab-on-a-chip idea.
From Wired, this is look at the probiotic movement. As any new health food fad the claims far outreach the clinical trials.
From Biocompare, so engineers have been looking for ways of stopping liquefaction. The solution: bacteria. Using common soil bacteria with nutriants and oxygen, scientists have lab-tested bacterial metabolism to create calcite from sand.
An abstract talks about how the combination of a milk protein, Lactoferrin and pennicillin G on pennicillin-resistant Staphylococcus aureus.
From the Christian Science Monitor, a study looking at soil respiration, finds that with increased temperatures, mushrooms, roots and other soil organisms will not released as much of CO2 as previously thought. The only thing wrong (and I’m nit-picking) is that the author said that mushrooms are the “tiniest terrestrial inhabitants.” Mushrooms can be some of the biggest organisms on the planet.

From Physorg, a look at Lake Vostok in Antarctica. I think they maybe doing a metagenome study.
This from Physorg.com, is a discovery of a new type of algae. Being akin to red algae, picoplankton was uncovered by biochemical means.
So here’s a couple of articles about bacteria:
1) A reexamination of some microfossils seem to be giant baceria not animals.
2) How do we power things when oil is too expensive? Use bacteria of course. An indepth look at one lab’s work.
3) This looks at the microfauna of the gut and seems to indicate the types of bacteria in your gut determines the intake of nutrients and by extention how fat you are.
