As the year closes out, we enter into the giving seasons of a variety of traditions. Lurking among the more pleasant types of giving is the 2013 – 2014 flu season, a viral gift that often keeps on giving. To combat this, reminders about the potential dangers of influenza and the importance of va... 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
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
Mould species of the genera Fusarium and Altenaria are considered the most important threats to Norwegian grain cereals because they produce toxins which can be a potential risk to food safety. F. avenaceum, the fungi most frequently isolated from Norwegian grain, produces enniatins which have b... Read More
From joint replacements to cardiac implants and dialysis machines, medical devices enhance or save lives on a daily basis. However, any device implanted in the body or in contact with flowing blood faces two critical challenges that can threaten the life of the patient the device is meant to hel... Read More
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
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
Questions are swirling around a science journal's decision last year to publish a description of a newly discovered botulinum toxin while omitting key genetic details that researchers would normally disclose. The unusual case highlights important unresolved issues in how to balance scientific op... Read More
The world of lipids does not always gets its due. Their oleaginous charm is not always appreciated, as we said here before. For example, have you heard of hopanoids? They are made by some bacteria and are an unusual kind of polycyclic lipids that resemble steroids, but with an extra ring. Just l... Read More
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
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
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...

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
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
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
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
