The coevolution of an ant and a fungi

"This segment from a PBS program entitled "Evolution: Evolutionary Arms Race" illustrates the coevolution of the leafcutter ant and the fungi on which it feeds. Leafcutters have been "farming" this fungus for millions of years by feeding, fertilizing, weeding, and harvesting it. Learn how one gr... Read More

Extract DNA from a Banana (Experiment)

The soft flesh of a banana provides a ready source of DNA. Using a few simple purification steps in a classroom setting, students can yield loads of crudely prepared DNA. To begin, the banana is mashed in a detergent/salt solution to lyse the cellular and nuclear membranes. Cellular lysate is st... Read More

Specially Engineered Bacteria Could Replace Diabetics' Insulin Shots With Insulin Yogurt Snacks

Developments in genetics are now making it possible to invite custom-engineered symbiotic creatures into our bodies to help perform the functions we can't. In two separate developments, scientists have created a strain of bacteria that stimulates insulin production in the stomach of diabetic mic... Read More

Engineered protein-like molecule protects cells against HIV infection

In a fundamental study of how to control protein shape, a UW-Madison research team has created a set of peptide-like molecules that successfully blocked HIV infection of human cells in laboratory experiments.

"By interacting with a piece of a crucial HIV protein called gp41, the synthetic mol... Read More

Organic vs. Conventional Beef - No Major Difference in Antibiotic Susceptibility of E. coli

A new study suggests that when compared to conventionally raised beef cattle, organic and natural production systems do not impact antibiotic susceptibility of Escherichia coli O157:H7. This discovery emphasizes that although popular for their suggested health benefit, little is actually known... Read More

Grim worst-case scenario for swine flu (video)

According to the CDC, deaths from this year's flu season could be double the average. Moreover, the pattern of infection is different than that of the regular flu; children and young adults are more at risk and H1N1 spreads easily. This three minute video gives an overview of the CDC's latest an... Read More

Satellites Used to Predict Infectious Disease Outbreaks

From avian flu to cholera, infectious diseases may not be able to hide for long. Some researchers have their sights trained on predicting their every move with detailed satellite data

Rather than searching for weird weather or enemy missiles, some satellites are helping researchers to track—a... Read More

Plant Protein 'Doorkeepers' Block Invading Microbes, Study Finds

A group of plant proteins that "shut the door" on bacteria that would otherwise infect the plant's leaves has been identified for the first time by a team of researchers in Denmark, at the University of California, Davis, and at UC Berkeley.

Findings from the study, which will appear June 29 ... Read More

Bacteria Desalinate Water, Generate Power

Researchers at Penn State University have engineered a microbial fuel cell which turns dirty salt water into electricity and drinkable water.

The researchers start with a cup full of water from a pond or other natural source. Among the millions of microbes in the sample, some of the bacteria... Read More

At The Fungal Farmer's Market, Only The Best Cyanobacteria Are For Sale
