Recovering viral genomes from ancient specimens can provide information about viral evolution, but not many old nucleic acids have been identified. A study of 700 year old caribou feces reveals that viruses can be protected for long periods of time – under the right conditions. Read More
Scientists from the University of Queensland and a biotechnology company discovered a new class of antibiotics, which is a kind of synthetic sugar. And the new antibiotics can significantly decrease the drug resistance caused by bacteria, and kill them. These new antibiotics can be a powerful dr... Read More
Rare is the holiday meal that does not owe many of its pleasures to invisible cooks with tongue-twisting names. Do you enjoy charcuterie and pickles? Bread with cultured butter? A drizzle of vinaigrette on this or that? A bit of cheese? Some chocolates? Wine, beer or cider? Then raise a glass to... Read More
Did you ever wonder what different virus infections you have had in your lifetime? Now you can find out with just a drop of your blood and about $25.
Immune defense systems of many hosts produce antibodies in response to virus infections. These large proteins, which are generally virus specif... Read More
“Wikipedia is the first place people go for information about science – and everything else,” says John Tracey, Research Assistant in Education & Outreach at the Simons Foundation. The Simons Foundation has teamed up with Google to sponsor the Wikipedia Year of Science 2016, an initiative to inc... Read More
Host: Jeff Fox with special guests, Ron Milo and Shai Fuchs.
Ron Milo of Weizmann Institute of Science in Rehovot, Israel, and Shai Fuchs at the Hospital for Sick Children in Toronto, Canada, talk with Jeff Fox about their efforts, with Ron Sender at Weizmann, to redetermine the ratio... Read More
How do we define the genetic makeup of an individual? Is it the genetic material found in each cell of that individual (that’s not entirely accurate; mutations and recombinatorial differences can lead to multiple genomes in one individual). And what about the genes carried by our microbiome? The... Read More
As the West African epidemic of Ebola virus grows, so does misinformation about the virus, particularly how it is transmitted from person to person. Ebola virus is transmitted from human to human by close contact with infected patients and virus-containing body fluids. It does not spread among h... Read More
In the United States, approximately 40,000 people die every year due to pancreatic adenocarcinoma, making it the fourth leading cause of cancer related death. Patients diagno... Read More
ASM Microbe is the new conference that merges the former General Meeting with the Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) to make one microbial sciences-packed meeting with something for everyone. Why institute one new meeting instead of maintaining two separate ... Read More
The human microbiome, the collection of trillions of microbes living in and on the human body, is not random, and scientists believe that it plays a role in many basic life processes. As science continues to explore and better understand the role of the human microbiome. A new report from the Am... Read More
If the DNA sequence of a cell is like the operating system of a computer, then the smallest cellular OS has just been written. Called Syn3.0, it encodes everything needed to make a viable, autonomously replicating cell.
Mycoplasma is a genus of bacteria that are the smallest known free-living... Read More

Species: Zika virus
Structure of Zika Virus
•The virion is approximately 40 nm in diameter with surface projections that measure roughly 5-10 nm.
•Nucleocapsid is 25-30 nm in diameter surrounded by a host-membrane derive... Read More
Having worked on viruses for over 40 years, I know a fair number of people in the field, and I am amazed at how many of them have started to work on Zika virus. What exactly is attracting virologists to this emerging virus?
There are probably many reasons why Zika virus would be of interest t... Read More

For anyone interested in Antibiotic Awareness Week, a big part of the story is that patients (or their parents) demand antibacterials even for viral infections. And doctors often comply, just to get rid of them (the patients, that is). This high-resolution PDF can be printed out for waiting ro... Read More
Read in near real-time a virologist's experiments on Zika Virus. Now with its fourth post the Zika Diaries aims to illuminate the public on what it takes to do research on this emerging outbreak. From the Racaniello Lab at Columbia Univ. -
"Now that my laboratory obtained a number of differe... Read More
Antigenic variation is a hallmark of influenza virus that allows the virus to evade host defenses. Consequently influenza vaccines need to be reformulated frequently to keep up with changing viruses. In contrast, antigenic variation is not a hallmark of poliovirus – the same poliovirus vaccines ... Read More
The microbes that call the New York City subway system home are mostly harmless, but include samples of disease-causing bacteria that are resistant to drugs — and even DNA fragments associated with anthrax and Bubonic plague — according to a citywide microbiome map published today by Weill Corne...
