Viruses take down massive algal blooms, with big implications for climate

Humans are increasingly dependent on algae to suck up climate-warming carbon dioxide from the atmosphere and sink it to the bottom of the ocean. Now, by using a combination of satellite imagery and laboratory experiments, researchers have evidence showing that viruses infecting those algae are d... Read More

Biomotor discovered in many bacteria and viruses

Nano-biotechnologists have reported the discovery of a new, third class of biomotor, unique in that it uses a "revolution without rotation" mechanism. These revolution biomotors are widespread among many bacteria and viruses.

The Ebola Outbreak: 'A Dress Rehearsal For The Next Big One'

Until this year, the world had recorded 1,640 deaths from Ebola since the virus was discovered in 1976.

Then Ebola appeared in West Africa.

So far this year, 887 people have died of Ebola in West Africa, the World Health Organization said Monday.

To put that into perspective, more than ... Read More

Asian Tiger Mosquito Could Expand Painful Caribbean Virus into U.S.

Rapid expansion of this species, which is more aggressive than the species that is now spreading chikungunya into the Caribbean, is worrying scientists.

In the past few months, passengers at North American airports have been warned that travel to the Caribbean might result in an unwanted souv... Read More

Seals Brought Tuberculosis to Americas

Ancient bacterial genome sequences collected from human remains in Peru suggest that seals first gave tuberculosis (TB) to humans in the Americas.

Modern TB strains found in North and South America are closely related to strains from Europe, suggesting that the Spaniards introduced the diseas... Read More

Mouth Bacteria Can Change Its Diet, Supercomputers Reveal

Bacteria inside your mouth drastically change how they act when you're diseased, according to research using supercomputers at the Texas Advanced Computing Center (TACC). Scientists say these surprising findings might lead to better ways to prevent or even reverse the gum disease periodontitis, ... Read More

Social networking is key to helping bugs spread, study shows

Bugs that can co-operate best with each other are most likely to be able to jump to new species, including humans, a new study shows.

Bacteria interact by releasing molecules to help them adapt to their environment – for example, when killing competing infections in their victim. They co-ord... Read More

Scientists Choose Sides In Safety Debate Over Lab-Made Pathogens

A smoldering debate about whether or not researchers should ever deliberately create superflu strains and other risky germs in the interest of science has flared once again.

Proponents of the work say that in order to protect the public from the next naturally occurring pandemic, they have to... Read More

Experts question value of common superbug control practices

The jury is still out on the effectiveness of meticillin-resistant Staphylococcus aureus (MRSA) superbug control policies in hospitals, according to leading infectious disease experts. In particular, screening and isolating infected patients -- which have long been regarded as the gold standard ... Read More

Scientists boost potential of passive immunization against HIV

Scientists are pursuing injections or intravenous infusions of broadly neutralizing HIV antibodies (bNAbs) as a strategy for preventing HIV infection. This technique, called passive immunization, has been shown to protect monkeys from a monkey form of HIV called simian human immunodeficiency vir... Read More

U.S. biosafety experts watch every step in care of Ebola patients

A U.S. hospital caring for two Americans carrying the deadly Ebola virus has tapped biosafety experts to ensure doctors, nurses and other staff do everything needed to prevent the virus from escaping from an isolation ward in Atlanta.

The two patients, humanitarian aid workers who became infe... Read More

The viruses that spread antibiotic resistance

Bacteriophages are viruses that infect bacteria, and in the great war between humans and pathogenic bacteria they can act as allies for both sides. Phages that destroy their host bacteria can be used as antimicrobial therapy, complementing or replacing antibiotics. On the other hand as phages ar... Read More

In Hunt For New Antibiotics, Scientists Look At Bacteria In Insects' Stomachs

Pampering leafcutter ants with fragrant rose petals and fresh oranges may seem an unlikely way to rescue modern medicine, but scientists at a lab in eastern England think it's well worth trying.

As the world cries out for new antibiotics, researchers at the John Innes Center (JIC) in Norwich ... Read More

Smart Bacteria Help Each Other Survive

The body’s assailants are cleverer than previously thought. New research from Lund University in Sweden shows for the first time how bacteria in the airways can help each other replenish vital iron. The bacteria thereby increase their chances of survival, which can happen at the expense of the p... Read More

Treating Cancer With Bacteria Shows Real Promise

n a groundbreaking study, researchers say injecting bacteria into a tumor helped shrink it.

Bacteria are generally considered more foe than friend, but that may change, if results from a pioneering study are confirmed.

Reporting in the journal Science Translational Medicine, scientists led... Read More

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

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

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

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
