The Wild Types
The Wild Types is an interview show about scientists hosted by Ushma Neill and Richard White. Ushma interviewed me for episode #2. The show name doesn’t refer to the fact that all scientists are wild (some are; I am not) but the genetic term referring to the strain or organism that is compared with mutants. As […]

The 100th birth anniversary of Jonas Salk
Jonas Salk, who lead the team that developed the first poliovirus vaccine, was born 100 years ago today, 28 October 1914, in New York City.

Ebola virus arrives in New York City
This morning I received this email from President Lee Bollinger: Dear fellow members of the Columbia community: As you may have seen in the media, Dr. Craig Spencer is being treated for Ebola at Bellevue Hospital in Manhattan. Dr. Spencer, an emergency department physician at NewYork-Presbyterian/Columbia University Medical Center, recently returned from a humanitarian mission […]

Could Reston virus be a vaccine for Ebola virus?
I have received many questions about whether immunizing with Reston virus could protect against infection with Ebola virus. Usually the question comes together with the statement ‘because Reston virus does not cause disease in humans’. I can think of two reasons why a Reston virus vaccine is not a good idea. There have been very few […]

How Firestone controlled Ebola virus disease in Liberia
When the first case of Ebola virus infection was detected at the Firestone Liberia, Inc. rubber tree plantation in March of this year, the company needed to prevent the virus from spreading among their 8,500 employees. The company established an incident management system, developed procedures for early detection of infection, enforced infection control guidelines, and […]

Can Ebola virus infect via the skin?
I received this question about Ebola virus infection via email: Can you become infected if infected droplet lands on your skin even if there is no abrasion on the skin? I am now hearing this, which surprises me. The virus can enter through the actual skin and does not need mucus membrane to enter? The […]

Small Things Considered
A blog for sharing appreciation of the width and depth of microbes and microbial activities on this planet.
TWiM #90: Think Globally, Act Locally
Vincent meets up with Laurene and David at the Annual Meeting of the Southern California Branch of the American Society for Microbiology, where they discuss how the Los Angeles County Department of Health is preparing for an outbreak of Ebola virus infection, and Cepheid’s game-changing, modular PCR system for the diagnosis of infectious diseases.
Pictures Considered #21. Southern Blot
by Christoph Weigel | "... These results, gained with a novel method for blotting (E. M. Southern, manuscript in preparation), have also led to the identification of the Bam Hl recognition sequence". It is rather unusual to find unpublished work referred to in the abstract of a paper, to put it mildly. But this was exactly what readers of the October issue...
Bacteria Allow Woodrats to Eat Poison
by Anne A. Madden | Many plants do not want to be eaten. They avoid this fate by producing deadly toxins and carcinogenic poisons, such as those associated with the aptly named poison ivy, poison sumac, and deadly nightshade. Despite such defenses, almost half of all animal species...
Talmudic Question #114
The year is 2124. Thanks to new improvements in teleportation, the Intergalactic Research Institute has gathered 1000 biological samples from each of 1000 habitable planets in 1000 galaxies. The samples were analyzed with new model Instant Analyzers capable of determining the nucleotide sequence bases (to use old quaint terminology) of…
Two More Questions about CRISPRs
by Merry Youle | Over the past eight years, step-by-step, researchers have established a basic understanding of the CRISPR defenses against foreign DNA so widely used by both bacteria and archaea. We related the early story on STC in 2008 and commented on six additional questions...
To Retract or Not to Retract… That’s the Question
In the previous post I discussed  that editors of Science asked for the retraction of a paper linking XMRV retrovirus to ME/CFS. The decision of the editors was based on the failure of at least 10 other studies to confirm these findings and on growing support that the results were caused by contamination. When the authors refused […]

Science Asks to Retract the XMRV-CFS Paper, it Should Never Have Accepted in the First Place.
Wow! Breaking! As reported in WSJ earlier this week , editors of the journal Science asked Mikovits and her co-authors to voluntary retract their 2009 Science paper . In this paper Mikovits and colleagues of the Whittemore Peterson Institute (WPI) and the Cleveland Clinic, reported the presence of xenotropic murine leukemia virus–related virus (XMRV) in peripheral blood mononuclear cells […]

Does the NHI/FDA Paper Confirm XMRV in CFS? Well, Ditch the MR and Scratch the X… and… you’ve got MLV.
The long awaited paper that would ‘solve’ the controversies about the presence of Xenotropic Murine Leukemia Virus-related virus (XMRV) in patients with chronic fatigue syndrome (CFS) was finally published in PNAS last week . The study, a joint effort of the NIH and the FDA, was withheld, on request of the authors , because it contradicted […]
