Recently identified cell-cycle controls are targets for new drugs that fight infections by shutting down division.
A cell is not a soap bubble that can simply pinch in two to reproduce. The ability to faithfully copy genetic material and distribute it equally to daughter cells is fundamental ... Read More
Australian researchers have found that zinc can 'starve' one of the world's most deadly bacteria by preventing its uptake of an essential metal.
The finding, by infectious disease researchers at the University of Adelaide and The University of Queensland, opens the way for further work to des... Read More
Myxomycetes are well-known as true slime molds whose plasmodia are increadibly beautiful. Plasmodial culture is a such kind of hard-working steps in working with the species of Kingdom Protista. Interestingly, they can unpredictably "move" around water agar dishes. Furthermore, they are in progr... Read More
Saudi Arabia says one more person has died from a new respiratory virus related to SARS, bringing to 55 the number of deaths in the kingdom at the center of the outbreak.
The Health Ministry said Sunday that the 37-year-old man died in Riyadh. He was among 130 people who have been infected wi... Read More
Potential new treatments for Ebola are to be tested in West Africa for the first time as part of an international initiative to fast-track trials of the most promising drugs against the disease that has already led to over 2,600 deaths.

Scientists are revealing how microbes living on floating pieces of plastic marine debris affect the ocean ecosystem, and the potential harm they pose to invertebrates, humans and other animals. New research being presented here today delves deeper into the largely unexplored world of the “Plasti... Read More
Research in mammals that aims to prevent future influenza pandemics raises ethical, public health concerns. Experiments creating dangerous flu strains that are transmissible between mammals pose too great a risk to human life from potential release, according to an editorial by researchers from...

A new biosensor quickly detects salmonella in food and can be easily customized to detect other types of bacteria—or even different strains for the same bacterium.
The process appears to easily outperform tests that are now standard in the food industry, according to researchers at Rice Unive... Read More
Animal genomes are known to contain captured retroviruses, typically referred to as endogenous retroviruses (ERVs). Many of these elements are still transcribed and are known to be involved in both beneficial functions in animal biology, such as placenta formation, and not-so beneficial functio... Read More
They have us surrounded. Even inside the spaces we build for ourselves — like homes and offices — we are a tiny minority. Invisible bacteria, fungi, and viruses outnumber us by orders of magnitude. We will always be outnumbered, but we may have a say in which microbes we’re surrounded by, accord... Read More
An unknown airborne environmental isolate on Mueller-Hinton agar exhibiting a single circular colony. White hyphal growth on the outer edges of the mold colony, where spores have not yet developed, surrounding the green and yellow grainy spore formation in the center of the colony with exudate ...

New adhesives based on mussel proteins could be useful for naval or medical applications.
Shellfish such as mussels and barnacles secrete very sticky proteins that help them cling to rocks or ship hulls, even underwater. Inspired by these natural adhesives, a team of MIT engineers has designe... Read More
Recent salmonella outbreaks that sickened at least 523 people and sent dozens to the hospital underscore “serious weaknesses” in the U.S. Department of Agriculture’s oversight of poultry plants, according to a study released Thursday by the Pew Charitable Trusts, which also criticized the govern...

George Washington had a collection of 476 kinds of pickles. To prevent scurvy, Christopher Columbus stocked pickles on the Niña, Pinta, and Santa Maria. Julius Caesar, believing pickles to be invigorating, added them to the Roman legions' diet. In 5000 BCE, the Babylonians were known for picklin... Read More
Getting the message out to the public that the microbial world is about much more than just diseases is a challenging topic, but one we should keep trying to improve on. There are many ways to do this, but as the saying goes, a picture is worth a thousand words, and most people don’t want to rea... Read More
Twenty-six species of Cryptosporidium have been recognised and 18 species declared non-valid in a recent shake-up of the parasite's taxonomy using DNA sequencing techniques.
Cryptosporidium is the second biggest cause of infant diarrhoea and death in developing countries, and is found across ... Read More
Introduced generalist plant viruses from other hosts that encounter native plant species for the first time pose a greater threat to plant biodiversity in south-west Australia than introduced specialist viruses, a recent study found.
The researchers compared impacts of six introduced generali... Read More
The mystery of alcoholic fermentations was uncovered in the first half of the 19th century by Cagniard-Latour (1837) in France, and Schwann (1837) and Kützing (1837) in Germany, based on microscopic studies but not without controversy. The great German organic chemist Justus Liebig did not like ... Read More
From the discovery of the first Neanderthal skull in a Belgian cave in 1826, a bone of contention among Homo sapiens has been the extent of our relationship to Homo neanderthalis, who disappeared from the fossil record ~30,000 years ago. Like scrappy cousins we'd rather not claim, we've attempte... Read More
A multi-disciplinary team from the University of Pennsylvania have published in Nature Methods a first-of-its-kind way to isolate RNA from live cells in their natural tissue microenvironment without damaging nearby cells. This allows the researchers to analyze how cell-to-cell chemical connectio... Read More
