Harvard Medical School researchers have engineered a photosynthetic cyanobacterium to boost sugar production, as a first step towards potential commercial production of biofuels and other biotechnologically and industrially useful carbon compounds. As feedstock producers, cyanobacteria have adva... Read More
There was a lot of interest in in TDR-TB Friday; both the Leonard Lopate Show on WNYC and Science Friday kindly asked me to be on to talk about it.
While I was waiting for the phone link to Science Friday to become live, an alarming bulletin arrived in my email. The early-warning list ProME... Read More
Changes in an overactive immune system can contribute to autism-like behaviors in mice, new research shows.
Scientists at the California Institute of Technology (Caltech) pioneered the study of the link between irregularities in the immune system and neurodevelopmental disorders such as auti... Read More
There may be a new wave of computer technology on the way thanks to scientists at the University of Leeds and Japan’s University of Agriculture and Technology: Growing your own computer.
Magnet-making bacteria may be used to create the next generation of hard drives, making them much smaller ... Read More
American students need a dramatically new approach to improve how they learn science, says a noted group of scientists and educators led by Michigan State University professor William Schmidt.
After six years of work, the group has proposed a solution. The 8+1 Science concept calls for a rad... Read More
Extensively Drug Resistant (XDR) Mycobacterium tuberculosis (MTB) was first encountered in 2006. Now as we enter 2012 we learn that a strain of MTB totally resistant (TDR) to all current antimicrobials has entered the Indian sub-continent . This new strain to India, TDR-MTB first emerged in ...

Farmers and ranchers will for the first time need a prescription from a veterinarian before using antibiotics in farm animals, in hopes that more judicious use of the drugs will reduce the tens of thousands of human deaths that result each year from the drugs’ overuse.
The Food and Drug Admin... Read More
Two controversial studies on bird flu will once again be reviewed by an expert committee that advises the government on what to do with biological research that could pose potential dangers.
The move is just the latest development in a fierce ongoing debate about genetically altered flu virus... Read More
Researchers from the Translational Genomics Research Institute, the Technical University of Denmark, and elsewhere used whole-genome sequence typing to retrace the evolutionary history of a methicillin-resistant Staphylococcus aureus strain currently found in livestock back to its antibiotic-sus...

The acquired immunodeficiency syndrome (AIDS) pandemic is caused by the human immunodeficiency virus (HIV-1), which attacks the immune system and leaves infected individuals susceptible to opportunistic infections. AIDS and HIV-1 are thought to have a relatively short history in humans, with the... Read More
We are surrounded by bacteria, viruses, fungi and parasites. The fact that we nevertheless do not fall prey to infections is thanks to certain cellular sensor molecules such as toll-like receptors (TLR), which recognize the molecular structure of pathogens and intercede by ensuring an often comp...

El podcast del microbio Nº 243 summarize the Science article by Abi-Rached et al. about the interbreeding between neandhertal an... Read More
The epidemiology episode with Michael Walsh was great. I loved the philosophical detour into counterfactual statements, time travel, and the meaning of causation. TWiV may indeed be viral, but from listening to it I fee... Read More
It may not be the latest style in bovine bling, but researchers at Princeton University say a golden tattoo attached to a cow’s tooth could one day tell you something about your health.
The remote sensing device has the ability to detect a single bacterium, and to demonstrate, scientists at P... Read More
In this Envisat image, a phytoplankton bloom swirls a figure-of-8 in the South Atlantic Ocean about 600 km east of the Falkland Islands.
During this period in the southern hemisphere, the ocean becomes rich in minerals from the mixing of surface waters with deeper waters. Phytoplankton depen... Read More
Treatment with lopinavir/ritonavir (Kaletra) reduced the risk that HIV-infected children would become co-infected with malaria, researchers said here.
Compared with treatment based on non-nucleoside reverse transcriptase inhibitors (NNRTIs), therapy with the protease inhibitor-based combinati... Read More
Respiratory Syncytial Virus is an extremely common infection in humans. Generally in healthy adults there is little or no disease but in infants or the elderly this lung infection can often be fatal and we do not yet have a vaccine. Over at Rule of 6ix, I ask a couple of questions to the first a... Read More
Cholera is an extremely virulent intestinal infection caused by ingestion of the bacterium Vibrio cholerae (V. cholerae). EU researchers elucidated the molecular mechanisms behind expression of virulence genes with important implications for new therapies.

Invasive species aren't just exotic animals, scary snakes or annoying insects. They can also be bacteria and viruses that kill people. Although it's difficult to say what the most harmful invasive species is, "I'd probably point to West Nile virus," says Christopher Dionigi of the federal Nation... Read More
Life in a high-pressured environment with practically nothing to eat might be ok for high-fashion models, but it’s an unlikely lifestyle choice for a single cell whose usual overriding goal is to become two cells. Yet the largest living ecosystem on Earth—the deep biosphere—is comprised of micro... Read More
