'No sex please, we're bacteria': A new type of reproduction

One species of bacteria seems to get many of the perks of sexual reproduction without actually having sex, a new study finds.

Different strains of bacteria called Mycobacterium smegmatis swap large, random bits of DNA prior to reproducing asexually. This process, known as conjugal transfer, p... Read More

The sorceress’s apprentice

ANYONE who walks in the woods will be familiar with witches’ brooms (pictured). Many trees sport these bushy tumours, which have a variety of causes. An important one is a group of bacteria called phytoplasma that are, in turn, carried from plant to plant by sap-sucking insects such as leafhoppe... Read More

UA Study on Flu Evolution May Change Textbooks, History Books

A new study published in the journal Nature provides the most comprehensive analysis to date of the evolutionary relationships of influenza virus across different host species over time. In addition to dissecting how the virus evolves at different rates in different host species, the study chall... Read More

Changing View on Viruses: Not So Small After All

There was a time not that long ago when it was easy to tell the difference between viruses and the rest of life. Most obviously, viruses were tiny and genetically simple. The influenza virus, for example, measures about 100 nanometers across, and has just 13 genes.

Those two standards, it’s n... Read More

Liquid soap in public toilets may be covering you in bacteria

Liquid hand soap in many public toilets is doing the opposite of improving hygiene, CCTV reports.

One sample was found to have 600 times more than the standard amount of bacteria, bringing it up to fast food ice levels of grossness. Experts warned that use of the soap could result in skin irr... Read More

Light zaps viruses: How photosensitization can stop viruses from infecting cells

A UCLA-led team of researchers has found evidence that photosensitizing a virus's membrane covering can inhibit its ability to enter cells and potentially lead to the development of stronger, cheaper medications to fight a host of tough viruses.

The UCLA AIDS Institute study, published in th... Read More

Concrete-Dissolving Bacteria Are Destroying Our Nation's Sewers

Underground in places nobody likes to look, bacteria are doing terrible things to our sewage pipes. The concrete pipes that carry our waste are literally dissolving away, forcing engineers into a messy, expensive battle against tiny microbes.

"The veins of our cities are in serious trouble, a... Read More

Vincent and friends,


While driving around a field cutting hay lost in my science podcast playlist the episode of TWIM #61 came up and I had to listen intently as salmonella typhimurium came up as this is a common enteric issue in agriculture. When ... Read More

In Search of the Perfect Gut Microbiome with a Tribe of Tanzanian Hunter-Gatherers

It might sound strange to say that humans have forgotten what human-food is, but many scientists believe this is the case. For thousands of years, the environment in which humans lived evolved at a glacial pace—our nutrition and culture changed slowly, and our bodies adapted to it at a matching ... Read More

Teen's biofuel invention turns algae into fuel

For a fifth-grade science fair, Evie Sobczak found that the acid in fruit could power clocks; she connected a cut-up orange to a clock with wire and watched it tick. In seventh grade, she generated power by engineering paddles that could harness wind. And in eighth grade, she started a project t... Read More

Finally, Clothing Designed to Stop the Spread of Germs on Public Transit

Of all the public transit etiquette violations out there, the sneeze-and-touch at the height of cold and flu season is among the worst. Everyone who rides in a city has seen it: that sickly looking person across the train or bus who sneezes into a free hand then grabs the pole we all share. Rese... Read More

The Energizer Bacterium

Many bacteria have a trick for surviving a water shortage: They dry up like raisins and turn into spores, protecting their essential genetic code. But moisten a spore and it swells right up again.

Those capabilities give bacterial spores some interesting potential as an energy source, as scie... Read More

Human Interferon Kills Resistant H7N9 Influenza - ICAAC 2013

During the April 2013 avian influenza A (H7N9) outbreak, more than 130 human infections with H7N9 were reported. Most patients had severe respiratory illness and 44 people have died. Studies suggest that the H7N9 virus has developed resistance to oseltamivir. A human interferon already in use fo... Read More

A retrovirus makes chicken eggshells blue

When you purchase chicken eggs at the market, they usually have white or brown shells. But some breeds of chicken produce blue or green eggs. The blue color is caused by insertion of a retrovirus into the chicken genome, which activates a gene involved in the production of blue eggs. Read More
