A Snippet: Antibiotics In The Nursery

You have heard of the leaf-cutting ants1 that meticulously cultivate "their" fungi2 which provide them with nutrients, and that, in addition, host actinobacteria which prevent bacterial and fungal infections of their fungi as well as their own infection by an entomopathogenic fungus3 Metarhizium...

WHO warns against 'post-antibiotic' era

The 'post-antibiotic' era is near, according to a report released today by the World Health Organization (WHO). The decreasing effectiveness of antibiotics and other antimicrobial agents is a global problem, and a surveillance system should be established to monitor it, the group says. There is ... Read More

Family Tree Of Pertussis Traced, Could Lead To Better Vaccine

Whooping cough was once one of the leading killers of babies around the world. Now that it's largely controlled with a vaccine, scientists have had a chance to figure out how the disease came into being in the first place. That story is told in a study published online this week in the journal m... Read More

Legionella outbreaks of Alcoy may have multiple sources

A genomic analysis has been carried out of Legionella pneumophila strains of 13 legionellosis outbreaks produced in Alcoy during the period from 1999 to 2010. Legionella pneumophila is a strictly environmental pathogen, an opportunistic bacterium that inhabits aquatic and soil environments, spre... Read More

Ebola Exacerbates West Africa’s Poverty Crisis

The virus spreading in Guinea, Liberia and Sierra Leone has led to food shortages and neglect of other devastating tropical illnesses.

When Ebola came to Dorcas's home on the outskirts of Freetown in Sierra Leone, the virus spared no one. Her mother brought it home from the clinic where she w... Read More

New analysis of 'swine flu' pandemic conflicts with accepted views on how diseases spread

The most detailed analysis to date of the spread of the H1N1 2009 pandemic influenza virus, known informally as ‘swine flu’, has found that short-range travel was likely the primary driver for the 2009 pandemic in the United States, in contrast with popularly accepted views on the way diseases s...

Healthy humans make nice homes for viruses

The same viruses that make us sick can take up residence in and on the human body without provoking a sneeze, cough or other troublesome symptom, according to new research. On average, healthy individuals carry about five types of viruses on their bodies, the researchers report. The study is the... Read More

Engineers design ‘living materials’ - Hybrid materials combine bacterial cells with nonliving elements that can conduct electricity or emit light

Inspired by natural materials such as bone — a matrix of minerals and other substances, including living cells — MIT engineers have coaxed bacterial cells to produce biofilms that can incorporate nonliving materials, such as gold nanoparticles and quantum dots.

These “living materials” combin... Read More

Ebola genomes sequenced

Speedy analysis reveals mutations, insights into outbreak, along with clues to origin, spread.

Responding rapidly to the deadly outbreak of Ebola virus disease (EVD) in West Africa, a team of researchers from the Broad Institute and Harvard University, working with the Sierra Leone Ministry o... Read More

Scientists: Mosquito Virus Spreads to Americas

A nasty virus first detected in Africa that is spread to people by the bite of infected mosquitoes is being locally transmitted in the Americas for the first time on the tiny French Caribbean dependency of St. Martin, health officials said Tuesday.

Epidemiologists have so far confirmed about ... Read More

Old drug may be key to new antibiotics

McMaster scientists have found that an anticonvulsant drug may help in developing a new class of antibiotics.

Although dozens of antibiotics target what bacteria do, their study has looked at how a certain part of bacteria are created, and they found there is a way of stopping it.

The disc... Read More

Warmer temperatures push malaria to higher elevations

Researchers have debated for more than two decades the likely impacts, if any, of global warming on the worldwide incidence of malaria, a mosquito-borne disease that infects more than 300 million people each year. University of Michigan ecologists and their colleagues are reporting the first har... Read More

Airborne Environmental Isolate #3

An unknown airborne environmental isolate on Mueller-Hinton agar exhibiting a single circular colony. White hyphal growth on the outer edges of the mold colony, where spores have not yet developed, surrounding the red/pink grainy spore formation in the center of the colony. This sample grew at ...

Microbes Defy Rules of DNA Code

The instructions encoded into DNA are thought to follow a universal set of rules across all domains of life. But researchers report in the May 23 issue of Science that organisms routinely break these rules.

The finding has implications for the design of synthetic life: by designing organisms ... Read More

The Way You’re Born Can Mess With the Microbes You Need to Survive

Throughout the animal kingdom, mothers transfer microbes to their young while giving birth. Different species of tadpoles acquire specific skin bacteria from mother frogs even though they all live in the same pond with the same bacterial background. Emerging chicken eggs get inoculated with micr... Read More

Herpes infected humans before they were human

Researchers have identified the evolutionary origins of human herpes simplex virus (HSV) -1 and -2, reporting that the former infected hominids before their evolutionary split from chimpanzees 6 million years ago while the latter jumped from ancient chimpanzees to ancestors of modern humans -- H...

DIY Droplet Lens, finalist, 2014 Eureka Prize for Innovative Use of Technology

The traditional light microscope is bulky and expensive. Dr Tri Phan and Dr Steve Lee from the Garvan Institute of Medical Research and Australian National University used gravity to manufacture high-performance polymer lenses. These can be seamlessly integrated with 3D printing and mini-LEDs to... Read More

Bacterial Gut Biome May Guide Colon Cancer Progression

Colorectal cancer develops in what is probably the most complex environment in the human body, a place where human cells cohabitate with a colony of approximately 10 trillion bacteria, most of which are unknown. At the 2014 American Association for Cancer Research Annual Meeting in San Diego, re... Read More

Scientists Convert Bacteria from Free-living to Nitrogen Fixing

If you pull up a soybean or bean plant and shake off the dirt, you might see odd swellings or bumps, like rheumatic finger joints, on its roots. Inside the cool, soil-covered bumps are bacteria that are making nitrogen with the help of an enzyme, something chemical factories can do only with the... Read More

Malaria-carrying mosquitoes wiped out in lab with genetic method that creates male-only offspring

Scientists have modified mosquitoes to produce sperm that will only create males, pioneering a fresh approach to eradicating malaria. Since 2000, increased prevention and control measures have reduced global malaria mortality rates by 42 per cent, but the disease remains a prevalent killer espec... Read More
