Although natural selection is often thought of as a force that determines the adaptation of replicating organisms to their environment, Harvard researchers have found that selection also occurs at the level of neurons, which are post-mitotic cells, and plays a critical role in the emergence of A...

Most would choose the cuddly gerbil over the much-maligned rat. But the latter's bad reputation may not be fully deserved. Central Asian rodents, not rats, prospering under warm variations in climate, could have been to blame for the arrival of the Black Death in Europe in 1347 and for repeated ... Read More
Genetic factors could play an important role in whether people survive the Ebola virus, say US scientists.
A study of mice infected with the virus found they showed a number of different symptoms, with 19% remaining unaffected by the disease.
This could explain why some people recover from... Read More
From November 2010: http://subtledesigner.blogspot.com/
So this year we really tried hard to geek out with the Christmas tree decorations (not that we haven’t done this before). We went with a 'microscopic universe' theme complete with DNA garland (made from pipe cleaners), micro-organism o... Read More
My global video challenge is about microorganism not yet cultivatable or difficult to cultivate in the laboratory. With new microorganism cultivation techniques is possible the discovery of new microorganisms. Read More
The first of a group of 10 American aid workers who may have come into contact with the Ebola virus in Sierra Leone were evacuated on Saturday, American government and aid officials said. They will be the largest group of Americans to have returned home over fears of exposure to the virus since ... Read More
The Human Microbiome Project revealed tens of trillions of microbes residing in and on humans. Now scientists are taking a census of plant microbes—and not just the hundreds of billions found in soils. Distinct microbial communities live inside roots, on leaves and within flowers, and all in all... Read More
The picture was taken for my master thesis in 2005.

Beautiful metallic colonies of E. coli growing on Endo agar which is being used mostly for differentiation and isolation of Enterobacteriaceae strains.
Because viruses must bind to cell surface molecules to initiate replication, the use of soluble receptors to block virus infection has long been an attractive therapeutic option. Soluble receptors have been developed that block infection with rhinoviruses and HIV-1, but these have not been licen... Read More
The fact of using antibiotics in aquaculture has immersed a multiresistance in pathogenic bacteria. This is why a spare solution had to be found which is the probiotics. So for that, I isolated lactic bacteria (lactobacilles) from the intestine of a pelagic fish (sardina pilchardus) and did a lo... Read More
New research from the University of Queensland has shown how zinc "tricks" an essentialmManganese-transport protein of S. pneumoniae into a shape in which it can't accept manganese. It is known that manganese is essential for S. pneumoniae infection to occur, so this research offers a chance to... Read More
While I was working on the “H1N-What?” post, I also knew there would soon be questions about MERS (Middle East Respiratory Syndrome), just as there were about SARS. So here are the essentials of what we know and don’t know about MERS—which has just been reported in the U.S.—as well as intriguing... Read More
A University of Florida research team is cautiously optimistic after finding a possible treatment in the lab for citrus greening, a disease devastating Florida’s $9 billion citrus industry. It is the first step in a years-long process to bring a treatment to market.
Claudio Gonzalez and Graci... Read More
Scientists working to understand the devastating bat disease known as white-nose syndrome (WNS) now have a new, non-lethal tool to identify bats with WNS lesions —ultraviolet, or UV, light.
If long-wave UV light is directed at the wings of bats with white-nose syndrome, it produces a distinct... Read More
Emulsifiers, which are added to most processed foods to aid texture and extend shelf life, can alter the gut microbiota composition and localization to induce intestinal inflammation that promotes the development of inflammatory bowel disease and metabolic syndrome, new research shows.

How often have you heard of two or more bacterial species coexisting within the same cell of a host? It’s known to happen with some frequency in some amebas, insects and other invertebrates (including the strange case of the mealybug bacteria, which have an endosymbiotic bacterium that carries a...

A common plant puts out a welcome mat to bacteria seeking to invade, and scientists have discovered the mat's molecular mix. The study published this week in the Proceedings of the National Academy of Sciences reveals new targets during the battle between microbe and host that researchers can ex... Read More
In one of the most comprehensive analyses of immune function performed to date, researchers analyzed blood samples from 105 sets of healthy twins. They measured immune cell populations and their chemical messengers—204 parameters in all—before and after participants received a flu shot. Differen... Read More
Some researchers who study the virus that causes Middle East respiratory syndrome got an early Christmas present: permission to resume experiments that the federal government abruptly halted in October.
The scientists were trying to modify the MERS virus so that it's better able to sicken mic... Read More
