We are, supposedly, outnumbered in our own bodies. We play host to an extraordinary menagerie of bacteria and other microbes—the microbiome—and it’s frequently said that these teeming cells outnumber our own by ten to one. This 10:1 ratio crops up everywhere. It appears in scientific papers, blo... Read More

In episode #3 of the new science show This Week in Evolution, Nels and Vincent examine another important driver of evolution: recombination. The results of two papers in which the process is studied in finches and in yeast lead to the unexpected conclusion that recombination evolves more slowly ... Read More
As we’ve seen in numerous cases in 2015, food contamination is a real issue for a number of different food types. Vegetable, meat, packaged, fresh – even pet food – we’ve seen too many examples of how bacteria can outsmart our best food safety practices. The Canadian government estimates 1 of ev... Read More
When the Ebola virus outbreak erupted in West Africa in 2014, children infected with the virus -- particularly those under age 5 -- faced overwhelming challenges. Not only was there a high death rate among young children infected with the disease, they often were isolated from their families, le... Read More
The Romans are well known for introducing sanitation technology to Europe around 2,000 years ago, including public multi-seat latrines with washing facilities, sewerage systems, piped drinking water from aqueducts, and heated public baths for washing. Romans also developed laws designed to keep ... Read More
Researchers have extracted the oldest complete genome sequence of a pathogen yet, from the body of the 5,300-year-old ice mummy Ötzi.
According to a January 7 paper in Science, the ‘Iceman’ was infected with the bacteriumHelicobacter pylori, which also plagues modern humans.
Few corpses h... Read More
Tropical diseases — some of them never before seen in the United States — are marching northward as climate change lets mosquitoes and ticks expand their ranges.
But that does not mean that epidemics will break out, scientists say. Whether a few cases explode into a full-fledged outbreak depe... Read More
After a six-year effort, researchers on the Spanish island of Majorca have rid several groups of Majorcan midwife toads of the pathogen Batrachochytrium dendrobatidis — better known as chytrid fungus, or B.d. It’s the first time the disease, which is devastating amphibians worldwide, has been er... Read More
Microbiologists have wondered whether flushing our toilets might be spreading faecal bacteria into the air around our homes, but thankfully that doesn’t seem to be the case. Only 0.4 per cent of those in the air were traced back to the toilet bowl – far less than the almost 9 per cent that came ... Read More
More than 40,000 women – some as young as 16 – have been recruited to carry out tasks normally only done by doctors and nurses: give childhood vaccinations, provide antenatal care, screen for deadly diseases and supervise their treatment.
In a post-Ebola world, these health-extension workers ... Read More
Helpful bacteria that live in the insect that transmits the pathogen associated with citrus greening disease may play a role in the pathogen’s spread.
A new study of the citrus greening bacterium’s effects on its insect vector, the Asian citrus psyllid, reveals multiple changes within the ins... Read More
I have worked on poliovirus for over thirty-six years, first as a posdoctoral fellow with David Baltimore in 1979, and then in my laboratory at Columbia University. The end of that research commences this year with the destruction of my stocks of polioviruses. Read More
SILVER SPRING, Md. - The Walter Reed Army Institute of Research (WRAIR) today announced the initiation of a Phase 2 clinical trial to evaluate the safety and immunogenicity of a prime-boost Ebola vaccine regimen in both healthy and HIV-infected study volunteers. Read More
A streamlined protocol for an alternative gene insertion method using genome editing technologies, the PITCh (Precise Integration into Target Chromosome) system, has been reported in Nature Protocols by Specially Appointed Lecturer Tetsushi Sakuma, Professor Takashi Yamamoto, Specially Appointed...
