Eighty-six years after the discovery of penicillin, docs are running out of antibiotics to treat serious infections like Clostridium difficile and gonorrhea, according to the Centers for Disease Control and Prevention. At the same time, the discovery of new "wonder drugs" has slowed, and microbi... Read More
Since the 1950s farmers have fed antibiotic growth promoters (AGPs) to livestock. Overusing these substances can create superbugs, pathogens that are resistant to multiple drugs and could be passed along to humans. Mindful of that, companies such as Perdue Farms have stopped using the drugs to m... Read More
Chinese researchers have discovered what they say is the first ‘virological penicillin’ – MIR2911, a molecule found naturally in a Chinese herb called honeysuckle.
Honeysuckle (Lonicera japonica) is a well-known Chinese herb. In Traditional Chinese Medicine, it has been used to effectively tr... Read More
More than 15 million people in the United States live with food allergies that impact every meal they eat. For some, accidentally ingesting a snack that their body deems taboo can ignite a violent biological response. Every three minutes someone is rushed to the emergency room due to a food alle...

The fungus responsible for an outbreak of contaminated Greek yogurt last year is not harmless after all but a strain with the ability to cause disease, according to research. "When people think about food-borne pathogens, normally they list bacteria, viruses, and maybe parasites. Fungal pathogen... Read More
A former student dropped by my lab this morning, and brought me a gift: a knit bacteriophage! Many times, as educators, we hear what we haven't done well, or could do better. Sometimes, like today, we get a priceless "thank you" from a former student. Read More
It is a fascinating quirk of nature: Simple bacteria have an immune system with a memory, which allows them to destroy invading viruses they have encountered in the past.
The phenomenon is more than just a scientific curiosity. In just two years, scientists have discovered how to repurpose th... Read More
Plastic is well-known for sticking around in the environment for years without breaking down, contributing significantly to litter and landfills. But scientists have now discovered that bacteria from the guts of a worm known to munch on food packaging can degrade polyethylene, the most common pl... Read More
Scientists from the University of Bern have developed a novel substance for the treatment of severe bacterial infections without antibiotics, which would prevent the development of antibiotic resistance.
Ever since the development of penicillin almost 90 years ago, antibiotics have remained t... Read More

The first microscopes, in the 1500s and 1600s, transformed glass panes that looked completely transparent into a universe teeming with bacteria, cells, pollen and intricate crystals. These visionary aids were the first devices to show people that there were cells within a drop of blood. Since th... Read More
Malaria: shaking chills & fever (followed by sweats, not specifically mentioned in this case), is a characteristic of malaria that is unforgettable once one has had it (I had malaria four times).
Thick blood smears is de rigueur.
New results from a safety and immunogenicity study, which included a challenge phase to test efficacy, indicate that a live attenuated enterotoxigenic Escherichia coli (ETEC) vaccine candidate, given in combination with a novel adjuvant, provided significant protection against disease. This repr... Read More
The calorie free sweetener erythritol is widely used in Asia; it is also gaining popularity in Europe and America. At the Vienna University of Technology, a new cheap method has been developed to produce erythritol from straw with the help of mould fungi.
Erythritol has many great advantages:... Read More
A little-known virus that can be fatal in young babies has prompted Queensland scientists to undertake urgent medical research.
Parechovirus was first reported in Australia in December last year and there have now been dozens of cases across the country.
There have been 11 confirmed cases ... Read More
Researchers at ETH Zurich have isolated a protein from a fungus of the spruce which combats nematodes. The scientists hope that toxins of this kind will become the basis for the vaccination of livestock or domestic animals against zooparasitic nematodes.
Most terrestrial plants enter into bio... Read More
Look what the cat dragged in! The parasite Toxoplasma gondii, a common protozoan transmitted by cats, can effect mammalian brain cells in strange ways. In rodents, the parasite has been shown to inhibit fear and actually attract them to the smell of cat urine. Humans can be infected through c... Read More
