Many double-stranded DNA viruses infect cells by ejecting their genetic information into a host cell. But how does the usually rigid DNA packaged inside a virus' shell flow from the virus to the cell?
In two separate studies, Carnegie Mellon University biophysicist Alex Evilevitch has shown t... Read More
The people of Guinea have been locked in a life-and-death struggle with Ebola virus since last December. Nearly 60 percent of Guineans infected with the virus since then have died. To cope with the unprecedented disease, the government went so far as to ban soup made from bats.
Why bats? Bec... Read More

(A) Staphlococcus aureus, (B) Bacillus stearothermophilus, (C) Pseudomonas fluorescens and (D) Escherichia coli were grown on TSA for 24 hrs at varying incubator temperatures (4, 25, 40, and 60 degree’s C). Note: The 4 degree plate were incubated for a week to get good Pseudomonas fluorescens ... Read More
The long-observed association between pneumonia and heart failure now has more physical evidence, thanks to research in the School of Medicine at The University of Texas Health Science Center at San Antonio.
The researchers found proof that Streptococcus pneumoniae, the leading cause of comm... Read More
Infections with the intestinal superbug C. difficile nearly doubled from 2001 to 2010 in US hospitals without noticeable improvement in patient mortality rates or hospital lengths of stay, according to a study of 2.2 million C. difficile infection cases.

Genetically manipulated yeast can produce morphine, which could help get around the problems with poppy crops, which include climate, disease and war. Karen Hopkin reports.
Yeast. They already participate in producing some of the most popular pain-killing substances around: beer and wine. Now... Read More
(A) Bacillus subtilis, (B) Staphlococcus aureus and (C) Escherichia coli were grown on BHI media with varying concentrations of NaCl (0.85%, 5%, 7.5%, 10%, and 20%) at 37 degrees C for 24 hrs. Read More
A Virginia Tech geobiologist with collaborators from the Chinese Academy of Sciences have found evidence in the fossil record that complex multicellularity appeared in living things about 600 million years ago – nearly 60 million years before skeletal animals appeared during a huge growth spurt ...

New adhesives based on mussel proteins could be useful for naval or medical applications.
Shellfish such as mussels and barnacles secrete very sticky proteins that help them cling to rocks or ship hulls, even underwater. Inspired by these natural adhesives, a team of MIT engineers has designe... Read More
In 1976, a group of health workers took a pair of film cameras to what was then known as Zaire and documented their discovery of a new, deadly virus.
Today we know that virus as Ebola.
A 27-year-old Belgian microbiologist named Peter Piot and his colleagues were the first to scientifically... Read More
"If you want to find unique diversity and if you want to find a wide range of different below-ground organisms, you don't have to travel around the world. You can walk across Central Park."
That statement comes from Noah Fierer, an ecology and evolutionary biology professor at the University ... Read More
A) Bacillus subtilis, (B) Staphlococcus aureus and (C) Escherichia coli were grown on BHI media with varying concentrations of NaCl (0.85%, 5%, 7.5%, 10%, and 20%) at 37 degrees C for 24 hrs. Read More
Influenza infection can enhance the ability of the bacterium Streptococcus pneumoniae to cause ear and throat infections, according to research published ahead of print in the journal Infection and Immunity.
In the study, the investigators infected mice with either influenza alone, pneumococc... Read More
Dangerous new pathogens such as the Ebola virus invoke scary scenarios of deadly epidemics, but even ancient scourges such as the bubonic plague are still providing researchers with new insights on how the body responds to infections.
In a study published online Sept. 18, 2014, in the journal... Read More
(Re-)Introducing the Pseudomonads. Despite the somewhat murky provenance of their name, pseudomonads are everything but "pseudo-" in terms of their metabolic versatility: they are bacterial omnivores, heterotrophs yet far from picky. Members of the family Pseudomonadaceae (Gammaproteobacteria) a... Read More
If the past few years have taught us anything, it’s that our well-being is intimately linked to the health of animals.
The current Ebola epidemic probably got its start when someone came into contact with an infected animal, perhaps a monkey or a fruit bat. The virus causing Middle East respi... Read More
The Epstein–Barr virus and its relatives in the herpesvirus family are known for their longevity. They persist in host tissues for years, causing diseases like mononucleosis, Kaposi's sarcoma and herpes, and are notoriously difficult to kill. University of California, Los Angeles, biophysicist Z... Read More
The world of lipids does not always gets its due. Their oleaginous charm is not always appreciated, as we said here before. For example, have you heard of hopanoids? They are made by some bacteria and are an unusual kind of polycyclic lipids that resemble steroids, but with an extra ring. Just l... Read More
