In this show, I report on three exciting stories: a bullet-shaped virus that could fight cancer, engineering a new genetic code, and purifying water using bacteria.
Research by scientists at the University of Missouri Center for Agroforestry suggests that buffer strips of grasses and other plants can trap and break down veterinary antibiotics in manure fertilizers.
Buffer strips have already demonstrated that they can be effective in protecting water qua... Read More
How many of you run into problems of false- positive PCR or lack of sensitivity in qPCR when trying to use 16S primers because of the background genomic DNA in your PCR enzyme mixes? At MO BIO Labs, we do.
This article is a review of a new paper in the Journal of Microbiological Methods (Novem... Read More
Chances are, in the course of your scientific career, you will encounter a common problem in research: losing time due to someone else’s mistake. Whether the problem is an incorrect strain or plasmid given to you by another lab, incorrectly made buffers or media from within your own lab, or, in ... Read More
A common bacteria found in many healthy adult females that can cause life-threatening infections when passed to newborns could be introduced to some women through frequent contact with cows, according to a research team led by a Michigan State University pediatrician.
The recently published f... Read More
Nestle chocolate morsels made in Wisconsin have tested positive for salmonella, according to a company spokeswoman.
This news follows a statement from the company in January that it again found a potentially fatal bacteria in its Toll House cookie dough.
There was no outbreak -- or recall ... Read More
Researchers at Washington University School of Medicine have found that the antibiotic Kanamycin (KM), which was previously believed to damage ears, actually has a protective effect against hearing loss in young mice when used in low doses.
KM is an antibiotic used to isolate bacteria and tre... Read More
Wrapping up one of its most vexing investigations, the FBI concluded that Army scientist Bruce Ivins acted alone in the 2001 anthrax mailings that killed five people and further unnerved a nation still reeling from the 9/11 attacks.
The agency formally closed the case Friday, ending the long... Read More

Corals around the world, already threatened by pollution, destructive fishing practices and other problems, are also widely regarded as among the ecosystems likely to be first — and most — threatened with destruction as earth’s climate warms.
But there is reason to hope, researchers are repor... Read More
Los temas que vamos a tratar esta semana son: tendencias hereditarias a contraer infecciones cerebrales, convertir biomasa en hidrógeno, termitas que producen un combustible alternativo y,... Read More
A company is planning to inject people with an HIV vaccine made of the deadly virus itself, albeit a deactivated version.
Vaccines against many viruses, including flu, are made from deactivated versions of those viruses, but such an approach was previously dismissed as too risky in the case o... Read More
Small Things Considered blogger Merry Youle has authored a post on the sequencing of Roseovarius nubinhibens. a bacterium that recently joined the group of about a thousand bacteria whose genomes have been sequenced. Researcher José González and colleagues in Mary Ann Moran's lab at the Universi... Read More
British researchers have devised a way to capture vaccines in a glass-like membrane composed of sugar, a feat that could eliminate the need for refrigeration of vaccines and revolutionize their distribution in the developing world. Tests have shown that the technique can preserve vaccines for as... Read More
A team of biologists has unraveled the biochemistry of how bacteria so precisely time cell division, a key element in understanding how all organisms from bacteria to humans use their biological clocks to control basic cellular functions.
The discovery, detailed in the February 19 issue of th... Read More
In a finding that bodes well for the development of new human antibiotics, Harvard researchers have determined the identity of the trigger that causes roundworm bacteria to excrete virulent substances.
Harvard Medical School Professor Jon Clardy teamed with researchers in the department of bi... Read More
When a bacterium evolves resistance to a particular antibiotic, it's problematic. When it evolves defenses against antibiotics in general, as Pseudomonas aeruginosa has done, it's terrifying. But now researchers have devised an antibiotic that attacks the germ in a completely new way that appear... Read More

Some of science's most powerful statements are not made in words. From the diagrams of DaVinci to Rosalind Franklins x-rays, visualization of research has a long and literally illustrious history. To illustrate is to enlighten. The National Science Foundation (NSF) and Science created the Intern... Read More
Since our most popular article of all time (“The Basics: How Ethanol Precipitation of DNA and RNA Works”) was published, many Bitesize Bio readers have asked us to further explain the difference between precipitating DNA with ethanol vs. isopropanol and which is the better choice. This article d... Read More
