10:06 PM | Spooky Spider
I love Halloween. It’s the time of year when I can leave all the spider webs up around the front stoop and call them decorations. This harmless garden spider, the Black and Yellow Argiope (Argiope aurantia) is not long for the world. She’ll die soon as the nights grow colder. But I’ll keep an eye on her wee ones in the egg sac she left by the railing. In the spring the baby spiders will hatch out, spin a little silk parachute to catch the breeze and sail away to a new home! […]

9:16 PM | CDC Guidance: Considerations For Discharging Persons Under Investigation For Ebola
CDC Infographic: Is it flu, or Ebola?   # 9268   As has already been demonstrated, while a fair number of people may be initially suspected of having Ebola, few will actually end up being infected with the virus. The CDC has fielded calls on scores of `suspected’ Ebola cases from hospitals around the country – performed testing on dozens – and yet only small handful have tested positive for the virus.    Today the CDC has issued guidance on […]

5:16 PM | Rediscovering some critical terms of use in microbial discussions: #microbiomania and #microbophobia
Earlier this week I was trying to come up with a short term to use when referring to the "Overselling of the Microbiome" and related hype. And I came up with one I really really like: microbiomania. The term just captures the essence of hype about microbiomes to me I guess.So - of course - the first thing to do was to see if anyone else used this term.  And the number one thing I looked at was domain names.  Nope.  Microbiomania.Com and Microbiomania.Org are now mine.  And […]

2:42 PM | All The Ebola News Not Fit To Print
      # 9266   Earlier this week a `fake’ news story made the rounds of Twitter and Facebook, suggesting that students at an Elementary school in Olanthe, Kansas had been infected with the Ebola virus.   When I was first alerted to the story, I did a quick search, found the offending article, and quickly determined it was fake.   Unfortunately, the story did what it was intended to to – it went `viral’ – and […]

5:13 AM | 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 It is rather unusual to find unpublished work referred to in the abstract of a paper, to put it mildly.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...

9:59 PM | CEO of Soylent goes even further off the deep end - going after his microbiome
Well, this is pretty deranged: Soylent CEO Is Lifehacking Water By Pissing In the Sink.  Forget all the wackiness of Soylent and the idea of limiting water intake.  And just look at the part of this on the micro biomeFeces are almost entirely deceased gut bacteria and water. I massacred my gut bacteria the day before by consuming a DIY Soylent version with no fiber and taking 500mg of Rifaximin, an antibiotic with poor bioavailability, meaning it stays in your gut and kills […]

8:39 PM | WHO Ebola Roadmap Update #10 – October 29th
  # 9265   The WHO announced the big jump in numbers during a press conference earlier today, but the actual PDF document has just gone live, giving us more detail.   Today’s report adds more than 3,500 cases to the total last reported on Saturday, but that number represents a `catch-up’ of cases over many weeks, not a sudden jump in cases.   While the total number of cases has increased, the number of deaths has actually gone down, as some […]

8:29 PM | Microbial Diversity: sometimes you have it, sometimes you don’t
This past January I wanted to see what would happen to my gut flora if I adopted a hunter-gatherer diet for a week – eating the plants, animals and drinking the same water as the Hadza hunter-gatherers of east Africa that I was working with. Among other hypothesis I wanted to test, would immersing myself [...]The post Microbial Diversity: sometimes you have it, sometimes you don’t appeared first on Human Food Project.

5:10 PM | This Month in Blastocystis Research (OCT 2014) - Trick or Treat Edition
Over the past 30 days I've hardly had any time to focus on Blastocystis. I've been busy preparing for and attending UEGWeek 2014, preparing abstracts for next year's ECCMID conference in Copenhagen, and I've also put a lot of effort into preparing proposals for this round of grant calls from the Danish Council for Independent Research.  Among other things, we are applying for money to develop DNA-probe based diagnostics, including a unique software, for use in the clinical microbiology lab […]
