Ötzi's non-human DNA: Opportunistic pathogen discovered in Iceman tissue biopsy


EURAC and University of Vienna discover an opportunistic pathogen in an Iceman tissue biopsy

Ötzi’s human genome was decoded from a hip bone sample taken from the 5,300 year old mummy. However the tiny sample weighing no more than 0.1 g provides so much more information. A team of scientist... Read More

How we used to talk about Measles

These days, the happiest place on Earth isn't so cheerful. In December, a large number of people started coming down with measles after visiting Disneyland in California. So far, about 80 measles cases have been reported in the state, an unusually large number for a virus that has long been unde... Read More

The Mind-Bending Power of Bacteria

Our bodies are home to a vast ecosystem of microbes — the microbiome — that has a powerful effect on the brain. Three brain researchers discuss the emerging connection between the brain and the gut, and whether microbes may help treat brain disorders.

Phages transducing antibiotic resistance detected in chicken meat

Bacteria resistant to antibiotics are on the rise. There are different explanations for how resistances are transferred. Researchers from the Vetmeduni Vienna found phages in chicken meat that are able to transfer antimicrobial resistance to bacteria. Phages are viruses that exclusively infect b... Read More

Fact or Faction?: Vaccines Are Dangerous

Overwhelming medical evidence proves that negative side effects are rare and minor

HIV strain matters for treating new cases

The specific strain of HIV that a person first contracts can have a lasting impact on how the virus disrupts his or her immune system, say researchers.

“This may have important implications for cure strategies aimed at eliminating the viral reservoir, as individuals infected with low replicat... Read More

Ten questions about Ebola virus (in Spanish)

The Ebola outbreak is out of control in Africa, but it is not a global threat, why? Read More

Enterovirus Likely to Spread Through Schools, Experts Say

A rare virus is marching through the Midwest just in time for back-to-school, the time of year when viruses start to spread rapidly between students before infecting the rest of the population.

The U.S. Centers for Disease Control and Prevention is looking into hundreds of suspected cases of ... Read More

Promising antibiotic discovered in microbial ‘dark matter’

An antibiotic with the ability to vanquish drug-resistant pathogens has been discovered — through a soil bacterium found just beneath the surface of a grassy field in Maine. Although the new antibiotic has yet to be tested in people, there are signs that pathogens will be slow to evolve resistan... Read More

Could Multiple Sclerosis Begin in the Gut?

Multiple sclerosis (MS) is an electrical disorder, or rather one of impaired myelin, a fatty, insulating substance that better allows electric current to bolt down our neurons and release the neurotransmitters that help run our bodies and brains. Researchers have speculated for some time that th... Read More

Virus-cutting enzyme helps bacteria remember a threat

Bacteria may not have brains, but they do have memories, at least when it comes to viruses that attack them. Many bacteria have a molecular immune system which allows these microbes to capture and retain pieces of viral DNA that they have encountered in the past, in order to recognize and destro...

Researchers Link Vaccine Effectiveness to Gut Bacteria

U.S. researchers have found a link between intestinal bacteria and the effectiveness of the flu vaccine. And the finding could have important implications for how vaccines are given.

Our intestines are full of bacteria; they help us digest our food. But scientists are starting to learn how im... Read More

Researchers eliminate HIV from cultured human cells for first time

HIV-1, the most common type of the virus that causes AIDS, has proved to be tenacious, inserting its genome permanently into its victims' DNA, forcing patients to take a lifelong drug regimen to control the virus and prevent a fresh attack. Now, a team of researchers has designed a way to snip o... Read More

Cell Discovery Could Lead to Strep Throat Vaccine

A new study clarifies how Group A Streptococcus (strep) bacteria resist the human immune system.

The research could eventually lead to the development of a safe vaccine against strep throat, necrotising fasciitis (flesh-eating disease), and rheumatic heart disease.

Previous efforts to deve... Read More

Transmission of Ebola virus

As the West African epidemic of Ebola virus grows, so does misinformation about the virus, particularly how it is transmitted from person to person. Ebola virus is transmitted from human to human by close contact with infected patients and virus-containing body fluids. It does not spread among h... Read More

Bacteria in Wine May be Good for Your Health

There are bacteria in wine that may be beneficial for people's health, new research finds.

In the study, researchers in Spain isolated 11 strains of bacteria from wine, including strains of Lactobacillus, which are also found in yogurt, as well as Oenococcus and Pediococcus bacteria, which ar... Read More

Ebola’s evolutionary roots more ancient than previously thought, study finds

A new study is helping to rewrite Ebola’s family history.

The research shows that filoviruses — a family to which Ebola and its similarly lethal relative, Marburg, belong — are at least 16-23 million years old.

Filoviruses likely existed in the Miocene Epoch, and at that time, the evolutio... Read More

An Ebola virus protein can cause massive inflammation and leaky blood vessels

Ebola GP protein covers the virus' surface and is shed from infected cells during infection. Shed GP can trigger massive dysregulation of the immune response and affect the permeability of blood vessels.
