In order to infect a host cell and proliferate, some viruses, such as the hepatitis C virus, infiltrate the ribosomes, the molecular machines that assemble the proteins present in each of our cells. Viral proteins are thus produced to the detriment of cellular proteins. A group of scientists in ... 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
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
Follow the reconstruction and simulation of poliovirus using the BlueGene/Q supercomputer at the Victorian Life Sciences Computation Initiative. The poliovirus model is being used as a basis for understanding antiviral drugs, virus infection and helps us to learn how to model related viruses suc... Read More
While human families are easily illustrated as a tree, bacterial families look more like a heap of branches. Scientists are trying to trace the connections between those branches in an effort to learn more about the bacteria that harm us, and those that do not.

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
Nora Besansky, O’Hara Professor of Biological Sciences at the University of Notre Dame and a member of the University’s Eck Institute for Global Health, has led an international team of scientists in sequencing the genomes of 16 Anopheles mosquito species from around the world.
Anopheles mosq... Read More
Vincent, Alan, Rich and Kathy discuss how interleukin 10 modulation of Th17 helper cells contributes to alphavirus pathogenesis.
Wolbachia pipientis is a worldwide bacterial parasite of arthropods that infects germline cells and manipulates host reproduction to increase the ratio of infected females, the transmitting sex of the bacteria. The most common reproductive manipulation, cytoplasmic incompatibility (CI), is expre... 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
DADA, this name made by E.coli by me... i am a big fan of Sourav Ganguly, thats why i made this thing using my Microbiological aspect............... Read More
Although it is far from unanimous, the great majority of phages studied so far package their genomes for intercellular space travel as linear chromosomes. Why linear rather than circular? Packaging convenience, for one thing. Many phages, including all of the tailed phages, package their chromos... Read More
Developing new drugs means researchers must observe how cells react to those drugs over extended periods of time. NSF-funded small business Phi Optics has developed an optical microscope that lets scientists do just that -- study living cells in their natural environments.

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
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
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
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
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 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
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
