Cell death, also known as apoptosis, is a significant part of normal animal development. However, the question arises whether bacteria, similar to higher organisms, have a built-in mechanism that determines when the cells die.
Researchers at the Hadassah Medical School of the Hebrew Universi... Read More
The more controversial of two papers describing how the lethal H5N1 bird flu could be made easier to spread was published on Thursday, six months after a scientific advisory board suggested that the papers’ most potentially dangerous data be censored.
The paper’s publication, in the journal S... Read More
Bacterial genomes differ dramatically in size: from 140Kb to 13Mb (those numbers might be off now...please let me know if something has broken the record. Yes, I know the lower estimate can change based on semantics, but there are a bunch in that range). Although we have some clues as to how sel... Read More
India has been free of polio for over one year. This is a remarkable accomplishment, considering that just 30 years ago the country recorded 200,000 cases of the disease annually, or one every three minutes. With polio endemic in two neighboring countries, Pakistan and Afghanistan, and in the mo... Read More
The use of probiotic bacteria, isolated from naturally-occurring bacterial communities, is gaining in popularity in the aquaculture industry as the preferred, environmentally-friendly management alternative to the use of antibiotics and other antimicrobials for disease prevention. Known to the p... Read More
Members of a U.S. government biosecurity advisory board are offering a range of reactions to the news that they are being asked to take a second look at two controversial flu studies. Some have not previously spoken publicly about the issue, which has sparked a global debate about biosecurity ve... Read More
Across the horizon and miles out to sea toward the north, the Atlantic Ocean's own spring and summer ritual is unfolding: the blooming of countless microscopic plant plankton, or phytoplankton.
In what's known as the North Atlantic Bloom, an immense number of phytoplankton burst into color, f... Read More
A third of the world’s human population is infected with a dormant tuberculosis bacteria, primarily people living in developing countries. The bacteria presents a lifelong TB risk. Recent research out of the University of Copenhagen demonstrates that the risk of tuberculosis breaking out is four... 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
One of the most economically devastating diseases in the world for those who raise cows, sheep, pigs, goats, deer and other cloven-hoofed animals is foot and mouth Disease (FMD). This incredibly contagious and fast-spreading disease causes fever, blisters on the feet and mouth (hence the name), ... Read More
A team of dentists and scientists from Newcastle University are developing a new product from a marine microbe to protect dentures, teeth and gums from bacteria in the mouth.
They are using an enzyme isolated from a marine bacterium Bacillus licheniformis found on the surface of seaweed which... Read More
The recent H1N1 flu pandemic was found to be particularly dangerous to obese people, and a Wayne State University researcher is looking for clues as to why.
Emily Martin, Ph.D., assistant professor of pharmacy practice in the Eugene Applebaum College of Pharmacy and Health Sciences, has begun... Read More
The superbugs have met their match.
Conceived at Nanyang Technological University (NTU), it comes in the form of a coating which has a magnetic-like feature that attracts bacteria and kills them without the need for antibiotics.
The killer coating, which has shown to destroy 99 per cent of... Read More
One year on from Europe’s worst recorded outbreak of Escherichia coli infection, governments have made little progress towards improving the monitoring and reporting systems that allowed the crisis to drag on for weeks. The disease, which was spread by contaminated fenugreek sprouts, swept acros... 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
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.

It was a provocative finding: strange bacteria in a California lake that thrived on something completely unexpected — arsenic. What it suggested is that life, a very different kind of life, could possibly exist on some other planet.
The research, published by a leading scientific journal in 2... Read More
Mothers with IgG antibodies to Toxoplasma gondii at delivery are at risk for later self-harm or suicide, particularly if they have higher titers against the parasite, a Danish study found.
The risk of self-directed violent behavior was increased 1.53-fold (95% CI 1.27 to 1.85, Psk rose to 1.9... 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
Cells on the move reach forward with lamellipodia and filopodia, cytoplasmic sheets and rods supported by branched networks or tight bundles of actin filaments. Cells without functional lamellipodia are still highly motile but lose their ability to stay on track, report researchers at the Stower... Read More
