How U.S. Hospitals Keep Deadly Germs Like Ebola Virus Contained

On Friday afternoon, the federal Centers for Disease Control and Prevention posted a guide explaining how hospitals should manage Ebola patients. Hospital workers entering a patient's room should wear:

- Gloves
- Gown (fluid resistant or impermeable)
- Eye protection (goggles or face shield... Read More

Ebola crisis: A doctor's view from Sierra Leone

West Africa's Ebola epidemic, the deadliest on record, presents particular challenges for medical staff. Here, Irish doctor Gabriel Fitzpatrick describes working for Medecins Sans Frontieres (MSF) at the centre of the outbreak in Sierra Leone:

MSF constructed a special Ebola treatment centre ... Read More

Microbiology: Microbiome science needs a healthy dose of scepticism

Explorations of how the microscopic communities that inhabit the human body might contribute to health or disease have moved from obscure to ubiquitous. Over the past five years, studies have linked our microbial settlers to conditions as diverse as autism, cancer and diabetes.

This excitemen... Read More

Gut Flora Influences HIV Immune Response

Normal microorganisms in the intestines appear to play a pivotal role in how the HIV virus foils a successful attack from the body’s immune system, according to new research from Duke Medicine.

The study, published Aug. 13, 2014, in the journal Cell Host & Microbe, builds on previous work fro... Read More

Preemies’ gut bacteria may depend more on gestational age than environment​

Scientists believe babies are born with digestive systems containing few or no bacteria. Their guts then quickly become colonized by microbes — good and bad — as they nurse or take bottles, receive medication and even as they are passed from one adoring relative to another.

However, in infant... Read More

Scientists hope bacterial blueprints will soon give doctors and nurses fewer sleepless nights

One of the most common types of bacterial infection might soon give doctors and nurses fewer sleepless nights, thanks to a discovery made by scientists at Trinity College Dublin. The scientists used X-ray crystallography techniques to provide a blueprint of the cellular machinery used by Pseudom... Read More

Ebola declared a public health emergency

World Health Organization announcement could shift focus to basic public health.

The escalating Ebola outbreak in West Africa poses an international threat and all countries must work together to contain it, the World Health Organization (WHO) said today (8 August). The announcement comes ami... Read More

Experimental Vaccine For Chikungunya Passes First Test

Scientists have taken the first steps to developing a vaccine for chikungunya — an emerging mosquito-borne virus that has infected more than a half million people in the Western Hemisphere this year. About 600 Americans have brought the virus to 43 states.

The study was small. Only 25 people ... Read More

Gut Microbes Browse Along a Gene Buffet

In the moist, dark microbial rainforest of the intestine, hundreds of species of microorganisms interact with each other and with the cells of the host animal to get the resources they need to survive and thrive.

Though there's a lot of competition in this vibrant ecosystem, collaboration is... Read More

Life Found 800 Meters Down in Antarctic Subglacial Lake

A cold breeze blew off the Antarctic plain, numbing the noses and ears of scientists standing around a dark hole in the ice. Flecks of ice crackled off a winch as it reeled the last few meters of cable out of the hole. Two workers in sterile suits leaned over to grab the payload — a cylinder the... Read More

Amyotrophic lateral sclerosis and viruses and my ice bucket challenge

Many people have a new awareness of the disease known as amyotrophic lateral sclerosis, or ALS, thanks to the Ice Bucket Challenge initiated by the ALS Association. Fewer might know that retroviruses have been proposed to play a role in the development of the disease. Read More

NIH Scientists Establish New Monkey Model of Severe MERS-CoV Disease (press release)

National Institutes of Health (NIH) scientists have found that Middle East respiratory syndrome coronavirus (MERS-CoV) infection in marmosets closely mimics the severe pneumonia experienced by people infected with MERS-CoV, giving scientists the best animal model yet for testing potential treatm...

Common tuberculosis vaccine can be used to prevent infection as well as disease

The vaccine used to protect against tuberculosis disease, bacillus calmette-guerin or BCG, also protects against tuberculosis infection, mycobacterium, as well as protecting against progression from infection to disease, finds new research. The BCG vaccine has been subject to numerous trials and... Read More

Editing HPV's Genes To Kill Cervical Cancer Cells

Researchers have hijacked a defense system normally used by bacteria to fend off viral infections and redirected it against the human papillomavirus (HPV), the virus that causes cervical, head and neck, and other cancers.

Using the genome editing tool known as CRISPR, the Duke University rese... Read More

Drug-Resistant Malaria Spreads Across Southeast Asia

Back in 2008, doctors in Cambodia made a worrisome discovery. They were having a hard time curing some people of malaria.

Even the most powerful drug wasn't clearing out the parasite from patients' blood as quickly as it should. Malaria had evolved resistance to the last medicine we have agai... Read More

Elusive viral 'machine' architecture finally rendered

Biologists have worked with the Lambda virus as a model system for more than 50 years but they've never had an overarching picture of the molecular machines that allow it to insert or remove DNA from the cells that it infects. Now they can, thanks to an advance that highlights the intriguingly i... Read More

Trapped: Cell-invading piece of virus captured in lab by scientists

Scientists try to stay a step ahead of HIV in order to combat drug resistance and to develop better treatments. When a person is infected with HIV, there is an initial burst of virus production. This is when integrase inserts the virus DNA into many human cells, including CD4 T-immune cells, bra... Read More

Experimental Medicine in a Time of Ebola

As the deadly outbreak of Ebola in West Africa continues to claim lives, Wellcome Trust director Dr Jeremy Farrar calls for Africans to be given access to experimental Ebola medication. This joint statement with Prof David Heymann, head of the Chatham House Centre on Global Health Security, and ... Read More

Rethinking The Origin of Species: Discover Magazine Features The Speciation Microbiome Project

From Discover: "Scientists have long known of the important roles played by the microbes on and in our bodies — our microbiomes. These little guys outnumber our own cells 10 to 1, and they help regulate everything from the energy we get out of food to the health of our immune systems. Now, scien... Read More

Scientists Finally Catch On to Social Media

In 2011, Emmanuel Nnaemeka Nnadi needed help to sequence some drug-resistant fungal pathogens. A PhD student studying microbiology in Nigeria, he did not have the expertise and equipment he needed. So he turned to ResearchGate, a free social-networking site for academics, and fired off a few e-m... Read More
