US Travelers Return Home With Tropical Disease. Will It Spread In The States?

If you happened to be reading state health departments’ outbreak announcements this past weekend, you might have seen something interesting.

(You don’t do this? Hmm.)

Three states — Rhode Island, North Carolina and Tennessee — all said that they have identified residents who have been diag... Read More

Bird flu 'danger zones' mapped

The "danger zones" in Asia which are vulnerable to a deadly bird flu have been mapped by scientists.

The virus, called H7N9, has infected 433 people mostly in China and has killed 62.

The study, published in Nature Communications, showed parts of Bangladesh, India and Vietnam could easily ... Read More

Probiotics to treat diseased coral? British scientist's suggestion

The possible applications of probiotics seem endless at times, don't they? New research from the University of Derby, and published in the 'Proceedings of the Royal Society B' looks closely at the microbes involved in certain diseases known to be killing corals.

Diseases threatening the lif... 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
