Organisms that have the catalase enzyme can detoxify the cell of hydrogen peroxide by converting it to oxygen gas. Bubbles indicate oxygen gas production after the addition of hydrogen peroxide directly to colonies growing on the TSA plate.
The bonded carbons are shown using E. coli, E. faecalis, and C. violaceum. Using BBL's CHROMagar, we were able to show the pi bonds in pink (E. coli) and blue (E. faecalis). Read More
Currently, it is well established that prokaryotes possess cytoskeleton and organelles. This image depicts how magnetic organelles, magnetosomes, are properly partitioned and segregated by a mechanism that relies on the treadmilling of a dedicated cytoskeletal structure, the actin-like MamK fila...

A team of researchers with members from Italy, Australia, the U.S. and Japan has found that viruses are the main culprit in killing archaea in the deep sea. In their paper published in the journal Science Advances, the researchers describe the techniques they used to study archaea in soil sample... Read More
The appearance of white blooms of plankton east of New Zealand suggests the ocean is responding to climate change, according to research by Victoria University of Wellington scientists.
As part of her Master's study, Bella Duncan investigated coccolithophores, a white algae with remains known... Read More
Researchers say there are 3 main factors that explain why women are more represented in some STEM (science, technology, engineering, and mathematics) fields than others.
The most powerful one, they say, is a “masculine culture” that makes many women feel like they don’t belong.
“There is w... Read More
In the new study, the scientists observed the virus's effects in animal models at two different points -- during early postnatal development, when the brain is growing rapidly, and at weaning, when the brain has largely reached adult size.
"In early postnatal Zika-infected models some brain a... Read More
A study published today in Ecology Letters adds to a growing body of work examining the relationship between harmful algal blooms in the Gulf of Mexico and agricultural runoff. The article focuses on water chemistry, specifically the ratio of dissolved silica to dissolved inorganic nitrogen in 1... Read More
Small regulatory RNA molecules are vital for salmonella and other bacteria potentially harmful to humans: This RNA type controls gene activity and allows bacteria to quickly adjust to changing conditions of living and stress as are typical during an infection, for example, when entering the bloo...

A new drug combination helped stave off a monkey version of HIV for nearly two years after stopping all treatments, raising hopes for a functional cure for HIV, U.S. researchers said on Thursday.
The treatment involved standard HIV drugs, known as antiretroviral therapy or ART, plus an experi... Read More
A device used during open-heart surgery that infected at least 12 patients at a Pennsylvania hospital last year was probably tainted at the plant in Germany where it was made, a federal investigation has found.
The device, called a heater-cooler machine, uses water to regulate the temperature... Read More
Florida announced a new Zika transmission zone on Thursday, saying that the virus had popped up in a mile-square patch of northern Miami and that five people had been infected.
The area, around the Little Haiti neighborhood, goes from NW 79th Street in the north to NW 63rd Street in the south... Read More
It is (almost boringly) obvious that cell-to-cell communication is vital in multicellular organisms. To function properly, all cells in a tissue have to know – and let their neighbors know – where exactly they are, which tasks they're performing right now, when it's time to differenti... Read More

The TWiVeroos examine a reverse spillover of Newcastle disease virus vaccines into wild birds, and identification of a protein cell receptor for murine noroviruses.
Guest host Lynda Coughlan reviews how oncolytic viruses, which specifically kill tumor cells, are designed and how they work. Read More
This photo was taken through a dissecting scope. Normally our Kocuria rosea display a smooth colony surface. One semester, they displayed a wrinkled surface. Last fall I observed a plate with both. October 2, 2015 Read More
Mix of organism seen on a handprint/finger on TSA after incubation at 37 degrees for 24 hrs then held at refrigerated temperatures for 1 month. Read More
Naturally occurring bacteria could consume pent-up hydrogen gas in nuclear waste repositories to prevent radioactive leaks, say researchers at EPFL.
Scientists may have found an unexpected ally in the long-term disposal of nuclear waste: bacteria. In a recent study, a research team led by EPF... Read More
Researchers from UPM have revealed how mold from humidity caused by rotting fruits and vegetables unfolds a surprising strategy to infect plants.
A team of researchers from Centre for Plant Biotechnology and Genomics (CBGP, UPM-INIA), has published the results on Alt a1 in an article release... Read More
