Starch Agar

Starch agar contains high molecular weight starch molecules (soluable starch). When Iodine is added it reacts with starch to produces a dark brown/purple color. A zone of clearing forms around organisms that produce the exoenzyme amylase after addition of iodine. This plate was incubated for ... Read More

Researchers create better methods to detect E. coli

Kansas State University diagnosticians are helping the cattle industry save millions of dollars each year by developing earlier and accurate detection of E. coli.

Lance Noll, master's student in veterinary biomedical science, Greensburg; T.G. Nagaraja, university distinguished professor of di... Read More

Algae able to switch quantum coherence on and off

A UNSW-led team of researchers has discovered how algae that survive in very low levels of light are able to switch on and off a weird quantum phenomenon that occurs during photosynthesis.

The function in the algae of this quantum effect, known as coherence, remains a mystery, but it is thoug... Read More

How the Body’s Cells Hold on Tight

When I was nine, biology gave me my first existential crisis. If I am built out of trillions of tiny cells, I worried, what’s to keep me from crumbling into a pile like a dried-out sandcastle? Almost two decades later, as a Ph.D. student in mathematics at the University of California, Davis, I’m... Read More

Leading virologists join together to tackle viruses, leukemia and neurologic disorders (press release)

The Global Virus Network (GVN) announced today the launch of a Task Force on HTLV, Human T-Lymphotropic Virus (HTLV), the world's first known human retrovirus and only known leukemia-causing virus. Experts from 11 countries*, led by Dr. Robert Gallo, GVN co-founder and scientific director and di... Read More

Researchers map gene differences in yellow fever, malaria mosquitoes, to help prevent disease

Virginia Tech entomologists have developed a chromosome map for about half of the genome of the mosquito Aedes agypti, the major carrier of dengue fever and yellow fever.

With the map, researchers can compare the chromosome organization and evolution between this mosquito and the major carri... Read More

Rocks and their microbes: a coevolutionary relationship

Miles beneath our feet, Earth’s rocky crust may seem a cold, dead place. On closer inspection it’s anything but.

Microbes have been making a home on and in rocks since…well, since the beginnings of life, some 3.5 billion years ago. The traditional view of rock-dwelling microbes is one of spar... Read More

Mutations during initial infection allows bacteria to evade immune response

Bacteria that cause ulcers in humans undergo accelerated evolution during the initial stages of infection, allowing them to evade the immune system, according to new research by an international team of researchers including Penn State scientists. The study shows, for the first time, and in real... Read More

HIV on Trial: An Attempt to Cure the World’s Smallest Patients

New global clinical trial aims to replicate the mysterious “Mississippi baby” success. When an infant born with HIV was reportedly “cured” of the disease it seemed too good to be true. The success, detailed by researchers in March 2013 and later published in The New England Journal of Medicine,... Read More

Exploring a Parasitic Tunnel Boring Machine

Parasitic worm genome and biology provides a solid basis for the development of new interventions. Researchers have deduced essential biological and genetic information from the genome sequence of the whipworm, an intestinal parasitic worm that infects hundreds of millions of people in developin...

'Sterile' Urine May Be a Myth

Many people have heard that human urine is devoid of germs, but a new study seems to question that idea.

"Doctors have been trained to believe that urine is germ-free," Dr. Linda Brubaker, dean of Loyola University Chicago Stritch School of Medicine, said in a university news release. "These ... Read More

New life form discovered at MSU, named after Bully

Some Mississippi State University students have discovered – and named – a new life form, a previously unknown organism discovered on campus in a mud puddle last September.

The newly classified organism – Ptolemeba bulliensis, a unicellular microscopic protest – was scooped from a courtyard b... Read More

Malnutrition: Starving Children Lack Crucial Gut Bacteria

When children are starving, the bacteria that live in their intestines may determine whether they can be saved, scientists working in Bangladesh are reporting. And they say it may become imperative to find a way to give children bacteria as well as food.

The study, done by researchers from Wa... Read More

Wood-aged cheese: How science slices the debate over bacteria

So what's the big stink over wood-aged cheese anyway? Is it deadly or just delicious?

Artisanal cheese-makers raised a fuss recently when an FDA official suggested that wooden cheese shelves posed a public health risk because they were not "adequately cleanable," and could therefore harbor d... Read More

TWiV 289: Vinny and the capsids

Vinny and the capsids answer listener questions about the definition of life, state vaccination laws, the basic science funding problem, viral ecology, inactivation of viruses by pressure, and much more.

Bacteria could restore uranium mining aquifers

Wyoming’s resurgent uranium industry could get a further boost from University of Wyoming scientists, whose research on post-mining environmental restoration is yielding promising results.

Research in UW laboratories has shown that stimulating growth of native bacteria could be a more effecti... Read More

How Probiotics Will Improve Your Skin

The more time I spend in the beauty industry, the more I believe that clear, good skin is more of an art than a science. Sure, it's science-based, but there's an endless list of the things that are bad (sun, dairy, gluten, oils) and only a few things that are good (vitamin D; dairy, unless you a... Read More

Origin of segmented RNA virus genomes

Segmented genomes abound in the RNA virus world. They are found in virus particles from different families, and can be double stranded (Reoviridae) or single stranded of (+) (Closteroviridae) or (-) (Orthomyxoviridae) polarity. Our recent discussion of the advantages of a segmented viral genome,... Read More
