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
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
Helicobacter is a Gram-negative rod with a helical shape on gram stain. The most known strain is H. pylori, which causes ulcers and chronic gastritis and is said to affect up to 50% of the human population. This particular strain, Helicobacter fennelliae is most commonly found in the feces an... 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
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
Resurrecting ancient beers and wines is a subtle alchemy, but Patrick McGovern knows all the tricks. He directs the Biomolecular Archaeology Project for Cuisine, Fermented Beverages, and Health at the University of Pennsylvania Museum. Many of his ancient brews are sold by Dogfish Head brewery i...

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
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

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
Rapid detection of antibiotic resistance is vital in assessing the appropriate antibiotic therapy for an infection. Participants will present data on two new inex... Read More
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
Pictured here is Rhodotorula, a beautiful coral-colored yeast grown on Sabouraud's Dextrose Agar.
Rhodotorula species are common environmental contaminants, found naturally in air, water, soil, and other areas. This yeast rarely is a pathogen, though it can cause infections in immumocompromis... Read More
