We now know that as many as 100 infectious bacteria, viruses, and fungi can be transmitted by air, either inhaled as they sail around or ingested after landing on a surface.
But in the ’60s and ’70s, the growing use of antibiotics and vaccines slowly relegated the study of airborne disease t... Read More
The TWiV gang reviews ten fascinating, compelling, and riveting virology stories from 2014.
An antibiotic with the ability to vanquish drug-resistant pathogens has been discovered — through a soil bacterium found just beneath the surface of a grassy field in Maine. Although the new antibiotic has yet to be tested in people, there are signs that pathogens will be slow to evolve resistan... Read More
On his second trip to Brazil, Vincent joins Eurico to speak with four young virologists, Gustavo, Cintia, Tatiana, and Suellen, about their work and their prospects for careers in science.

The aquarium looks empty, but there is something in it. A pair of eyes stick out from the sandy floor, and their owner is easily scooped up into a glass bowl. At first, the creature looks like a hazelnut truffle — small, round and covered in tiny flecks. But with a gentle shake, the flecks of sa... Read More
To slip, slide, squeeze and otherwise invade different parts of the body, cancer cells learn to switch between two modes of moving usually used by healthy cells. Now we know how.

A simple stain done on a stock culture of Aquaspirillum serpens to look at cell shape. This culture was grown in TSB at room temperature, ~21 degrees C, for several months. Aquaspirillum is a slow grower normally found in pond water. A characteristic spiral rod can be seen in the center of ... Read More
A deadly virus has claimed the lives of two of China's beloved giant pandas and left a third in critical condition.
Chinese state media reported this week that veterinarians are using antiviral therapy to treat five-year-old Feng Feng, after medical tests showed serious damage to the panda's ... Read More

Researchers from the University of Granada and the Higher Council of Scientific Research (CSIC) have found that hoophoes cover their eggs with a secretion produced by themselves, loaded with mutualistic bacteria, which is then retained by a specializad structure in the eggshell and which increas...

The microbiology market is segmented on the basis of applications into clinical, energy, environment, food, manufacturing, and pharmaceuticals. The pharmaceuticals application segment accounted for the largest share of the microbiology market in 2014, while the food application segment is expect... Read More
Two miles below the surface of the ocean, researchers have discovered new microbes that “breathe” sulfate.
The microbes, which have yet to be classified and named, exist in massive undersea aquifers — networks of channels in porous rock beneath the ocean where water continually churns. About ... Read More

DNA molecules provide the “source code” for life in humans, plants, animals and some microbes. But now researchers report an initial study showing that the strands can also act as a glue to hold together 3-D-printed materials that could someday be used to grow tissues and organs in the lab. This... Read More
When a rapidly-growing cell divides into two smaller cells, what triggers the split? Is it the size the growing cell eventually reaches? Or is the real trigger the time period over which the cell keeps growing ever larger?
A novel study published online today in the journal Current Biology ha... Read More
The National Institutes of Health has awarded grants totaling $7.9 million in 2014 to 25 research teams who are unraveling the workings of single cells, as part of an effort to spur development of personalized treatments that target disease at the cellular level. The grants are supported by the ... Read More
Wet mount examination of a stool specimen showing 2 eggs of the parasitic worm Hookworm. The eggs contain larva that are moving inside the egg and appear to be ready to hatch. Hookworm adult worm lays eggs that have a segmented ovum having 4-8 blastomeres and are not bile stained. Video captured... Read More
Scientists from St. Jude Children’s Research Hospital and China Agricultural University identify the changes in H9N2 flu virus in chickens that could signal emergence of viruses with potential to trigger a pandemic.
An international research team has shown how changes in a flu virus that has ... Read More
As you might expect for organisms that are billions of years old, bacteria have evolved lots of tricks to protect themselves in often-hostile surroundings. One of their most effective strategies is to coat themselves with a gooey layer, known as biofilm, which insulates them from predators, hars... Read More
