People may think of the plague as a disease from centuries past, but more than 1,000 people in the United States have become infected with plague in the last 100 years, according to a new study.
The researchers examined cases of plague in the United States from 1900 to 2012. During that time ... Read More
Researchers have made great progress in recent years in the design and creation of biological circuits — systems that, like electronic circuits, can take a number of different inputs and deliver a particular kind of output. But while individual components of such biological circuits can have pre... Read More

»I enjoyed the article on your blog 'Six Questions About CRISPRs' by Merry Youle. I am an ex-lambdologist, having quit phage lambda in the early 70s and moved to GM-plants. There is one thing about CRISPR that I do not understand: Why did lambdologists not find CRISPR?... Read More
Scientists looking to understand – and potentially thwart – the influenza virus now have a much more encompassing view, thanks to the first complete structure of one of the flu virus’ key machines. Knowing the structure allows researchers to finally understand how the machine works as a whole, a... Read More
Human influenza viruses replicate almost exclusively in the respiratory tract, yet infected individuals may also have gastrointestinal symptoms such as vomiting and diarrhea. In mice, intestinal injury occurs in the absence of viral replication, and is a consequence of viral depletion of the gut... Read More
Since the first “catalog” of the normal bacterial makeup of the human body was published in 2012, numerous connections between illness and disturbances in the human microbiota have been found. This week, scientists report yet another: Cancerous tumors in the ascending colon (the part nearest to ... Read More
The bed bug may be just as dangerous as its sinister cousin, the triatomine, or “kissing” bug. A new study from Penn Medicine researchers in the Center for Clinical Epidemiology and Biostatistics demonstrated that bed bugs, like the triatomines, can transmit Trypanosoma cruzi, the parasite that ...

Scientists review decades of work into bacterial proteins that transform iron and other minerals for energy and growth.
Cleaning up polluted soil and growing crops for biofuels benefit from a deeper understanding of how microbes alter subsurface minerals. Scientists at Pacific Northwest Natio... Read More
The test would quickly diagnose patients in remote locations where disease spread has been rampant.
Rutgers researcher David Alland, working with the California biotechnology company Cepheid, has received a grant of nearly $640,000 from the National Institutes of Health to develop a rapid tes... Read More
An important study conducted in part at the Department of Energy’s SLAC National Accelerator Laboratory may lead to new, more effective vaccines and medicines by revealing detailed information about how a flu antibody binds to a wide variety of flu viruses.
The flu virus infects millions of p... Read More
The Ebola crisis in West Africa is approaching the one-year mark, with no clear end in sight. At present, fewer than one in five people with Ebola is diagnosed within two days of becoming infectious, according to the World Health Organization (WHO). Yet in the absence of a safe and effective vac... Read More
Every disease has a history. Some of that history is written in books, and some is written in our DNA.
The earliest records of meningitis — an infection of the membranes that line the brain — reach back to 1685. The British physician Thomas Willis described fevered patients, some of whom suff... Read More
Yeast cells can sometimes reverse the protein misfolding and clumping associated with diseases such as Alzheimer’s, according to new research from the University of Arizona.
The new finding contradicts the idea that once prion proteins have changed into the shape that aggregates, the change i... Read More
Using mathematical modeling, researchers at New York and Vanderbilt universities have shown that commensal bacteria that cause problems later in life most likely played a key role in stabilizing early human populations. The finding, published in mBio, the online open-access journal of the Americ... Read More
A variety of Bacteria, Archaea, and mobile genetic elements replicate their DNA as a linear chromosome using terminal proteins (TPs) to prime DNA synthesis, thus solving their end replication problem. As described in an earlier post, phage φ29 uses its TPs to also organize the sites of DNA repli... Read More
A latest study led by University of Oslo and Dartmouth College researches shows that the underground microbes are actually social creatures and has swap genes for eons. It is expected that because oil reservoirs are spread deep inside the planet like distant islands in the ocean these creatures ... Read More
For practically our whole history of cooking and eating, we've gotten our spices and most flavors (not to mention all of the other basic nutrients that keep us alive) straight from plants.
But researchers and biotech companies are starting to produce some of these nutrients and flavors — espe... 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
The gut bacteria of a plastic-eating worm could help to break down the plastic waste clogging up landfills, according to a study published in Environmental Science & Technology.
Plastic remains in the environment for years without breaking down, contributing significantly to litter and landf... Read More
