Proteases are vital proteins that serve for order within cells. They break apart other proteins, ensuring that these are properly synthesized and decomposed. Proteases are also responsible for the pathogenic effects of many kinds of bacteria. Now chemists at the Technische Universitaet Muenchen ... Read More
The science behind the transformation from plants to milk to cheese is amazing. In fact, cheese has much in common with wine and beer: They result from fermentation by microorganisms; they are “value-added” products where processing greatly increases the value; and they reflect local climate and...

A team of researchers led by Virginia Tech and University of California, Berkeley, scientists has discovered that a regulatory process that turns on photosynthesis in plants at daybreak likely developed on Earth in ancient microbes 2.5 billion years ago, long before oxygen became available.

Two million people suffer antibiotic-resistant infections yearly, and 23,000 die each year as a result. Most of these infections occur in the community, but deaths usually occur in healthcare settings. Cost estimates vary but may be as high as $20 billion in excess direct healthcare costs.

Where humans travel, bacteria will follow. If people are in space for any amount of time, bacteria are sure to thrive there so it’s good to know that there are already researchers looking at how the environment within spaceships affects bacterial populations. Work done on planktonic colonies of ... Read More
Researchers at Columbia University are turning that optics-based imaging approach on its head, instead developing a chip based on integrated circuit technology that lets them not only electrochemically image bacteria, but listen in on them as well.

LEXINGTON, Mass. & CAMBRIDGE, Mass.--(BUSINESS WIRE)--February 13, 2014--
Cambridge Science Festival and Cubist Pharmaceuticals, Inc. (NASDAQ: CBST) today launched the 2014 "Germ Challenge," a contest designed to engage young people in science by inviting them to create educational and creativ... Read More
In this blog post, I show a science-cartoon by the great "Beatrice the Biologist" that illustrates an important point in my freshman introductory cell and molecular biology course: no matter how tired we might be, we are incredibly busy on a cellular level! Beatrice is a fine artist who underst... Read More
The bacterium Staphylococcus Aureus (S. aureus) is a common source of infections that occur after surgeries involving prosthetic joints and artificial heart valves. The grape-shaped microorganism adheres to medical equipment, and if it gets inside the body, it can cause a serious and even life-t... Read More
The environment significantly influences whether or not a certain bacterium will block mosquitoes from transmitting malaria, according to researchers at Penn State.
The researchers used a species of malaria parasite that affects rodents, Plasmodium yoelii, and the mosquito, Anopheles stephens... Read More
After having listened to your discussions on Plasmodium (TWiP 64), I explored papers on treatment options that are actually available. After having read some papers, I realized that one of the main roadblocks are the hypnozoite... Read More
The drug tamoxifen appears to kill a fungus associated with a deadly brain infection that afflicts HIV/AIDS patients, according to a University of Rochester study published online today by mBio, the journal of the American Society for Microbiology.

There are many elements that go into making a great lecture, but the most important one is to lose the notes. If you are giving lectures in a course at any level, the worst practice you can engage in is to rely on notes. This behavior is problematic for several reasons. You will not properly kno... Read More
Uno de los patógenos más importantes en América Latina y seguramente el mundo entero, el rotavirus, es discutido en este episodio de La Radio El Mundo de los Microbios. La Prof. Delfina Urbina, con una larga trayectoria en diferentes áreas de la Microbiología nos visita hoy. Fué Profesora Tit... Read More
For reasons that still aren't well understood, bacteria proliferate in microgravity. Creating a potential recipe for disaster for humans stationed in space for long periods, bacteria's love of low-g also raises an intriguing question: Why are they so comfortable there?

Washington University in St Louis chemist Timothy Wencewicz says we’ll stay ahead of antibiotic resistance only if we find drugs with new scaffolds, or core chemical structures. One promising candidate, an antibiotic made by a bacterium than infects plants, caught his attention because it contai... Read More
The hepatitis C virus (HCV) has a previously unrecognized tactic to outwit antiviral responses and sustain a long-term infection. It also turns out that some people are genetically equipped with a strong countermeasure to the virus' attempt to weaken the attack on it. The details of these findin... Read More
In his second expedition to South America, Darwin discovered many new species of animals and plants. The field observations obtained throughout this 5-year expedition provided the intellectual framework for the maturation of his ideas on evolution. It also introduced the world to a tiny (2-3 cm ...
