Bacteria swim with bodies and flagella

Using a new technique to track the swimming motion of a single bacterium, researchers have discovered that the movement of the bacterium’s body — not just thrust from the flagellum — allow movement through fluids. The finding could shed new light on the evolution of cell body shape.

Smallpox Virus Found In Unsecured NIH Lab

Scientists cleaning out an old laboratory on the National Institutes of Health campus in Bethesda, Md., last week came across a startling discovery: vials labeled "variola" — in other words, smallpox.

Under international convention, there are supposed to be only two stashes of this deadly vir... Read More

Yellow Light Grows the Best Algae for Biofuels

Aaron Wheeler is the director of an interdisciplinary research group at the University of Toronto in Canada. The group develop lab-on-a-chip techniques for applications in biology, chemistry and medicine.

You recently reported an exciting technique that can screen algae grown under different ... 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

Bacteria manipulate salt to build shelters to hibernate

For the first time, Spanish researchers have detected an unknown interaction between microorganisms and salt. When Escherichia coli cells are introduced into a droplet of salt water and is left to dry, bacteria manipulate the sodium chloride crystallisation to create biomineralogical biosaline 3...

The Hunt for Antibiotic-Resistance Hotspots

When patients take too many unnecessary antibiotics it inches us ever closer to a world where essential drugs are no longer effective. More than two million people in the United States develop antibiotic resistant infection each year and some 23,000 of them die as a result. Yet understanding the... Read More

Incidence of childhood tuberculosis could be 25 percent higher than previous estimates

New estimates indicate that over 650,000 children develop tuberculosis (TB) every year in the 22 countries with a high burden of the disease -- almost 25 percent higher than the total number of new cases worldwide estimated by WHO in 2012. The research also suggests that about 15 million childre... Read More

Plant Pathogen Silences Host’s Immune Genes

As more and more information becomes available, one marvels (and also frets) at the sophisticated strategies that pathogens have evolved in order to evade their hosts’ defense mechanisms. Many pathogens of plants and animals deliver effectors into their hosts in order to suppress immune response... Read More

Untapped Plant Microbiome Could Help Feed Billions

The Human Microbiome Project revealed tens of trillions of microbes residing in and on humans. Now scientists are taking a census of plant microbes—and not just the hundreds of billions found in soils. Distinct microbial communities live inside roots, on leaves and within flowers, and all in all... Read More

MERS virus detected in air samples from Saudi camel barn

Saudi scientists have found gene fragments of the deadly Middle East Respiratory Syndrome (MERS) virus in air from a barn housing an infected camel and say this suggests the disease may be transmitted through the air.

MERS, a serious respiratory illness caused by a virus known as a coronaviru... Read More

Sauerkraut: bacteria making food

Last week my husband needed some jars for cooking purposes. Tesco sell jars for somewhere around £3 each. However they also sell large jars full of sauerkraut for £1 each. Which means that last weekend we had an awful lot of sauerkraut to try and get through.

I’m not a great fan of sauerkraut... Read More

Esther Lederberg, Pioneer of Bacterial Genetics

“She did pioneering work in genetics, but it was her husband who won a Nobel price.” So said an obituary in the British newspaper The Guardian regarding Esther Lederberg, a North American microbiologist married to Joshua Lederberg from 1946 to 1966 [8]. Being married to and working along such a... Read More
