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
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
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...

Disruptions in the human circadian clock can throw off microbes in the gut, potentially boosting the risk of obesity, a new study suggests.
The results may help explain why shift workers and people who get jet lag by traveling frequently often pack on extra pounds.
"These surprising findin... 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
Wolbachia, a symbiont that resides naturally up to 70% of all insect species, are probably the most prevalent infectious bacteria on Earth. In 2008 Luis Teixeira, now a principal investigator at the Instituto Gulbenkian de Ciência, and other scientists have discovered that Wolbachia can protect ... 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
In addition to storing films, optical discs can be used to detect microorganisms, toxins, allergens and tumoral biomarkers. Blu-ray technology has allowed researchers to develop a way to find out if a sample contains Salmonella or toxic substances. This simple and cheap analytical system may be ... Read More
Cilia — short, hair-like fibers — are widely present in nature. Single-celled paramecia use one set of cilia for locomotion and another set to sweep nutrients into their oral grooves. Researchers at Brown have discovered that those two cilia sets operate at different speeds when the viscosity of... Read More
I have the grating feeling that the subject of self-assembly of complex biological structures may not always amass the level of respect it deserves. I reckon that its importance is generally appreciated but, as topics go, it tends at times to be set aside. Yet, this is one of the most magnificen... Read More
It has been proposed that rotavirus infection promotes the progression of genetically-predisposed children to type 1 diabetes, a chronic autoimmune disease marked by infiltration of activated lymphocytes into pancreatic islets. Non-obese diabetic (NOD) mice provide a model for the human disease.... 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...

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
Researchers will examine the role of gut bacteria in influencing the side-effects patients experience after radiotherapy, in the first clinical study of its type.
The study will be carried out by researchers at The Institute of Cancer Research, London, and The Royal Marsden NHS Foundation Tru... Read More
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
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
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 ...

Mothers give a newborn baby a gift of germs -— germs that help to kick-start the infant’s immune system. But antibiotics, used to fight bacterial infection, may paradoxically interrupt a newborn’s own immune responses. A new animal study by neonatology researchers at The Children's Hospital of P...

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
