3:52 PM | Nutcracker Man or Human Cow?
After discussing orbital forcing of climate and how we can judge its effects in the geological record, I thought I should return to talking about hominins, but not without a smooth segue between the two. Two more proxies can also indirectly tell us what ancient climate was like, and these are are isotopes of carbon, […]

1:00 PM | What we’re reading: The diversification of bacteria, landscape genomics of cottonwood, and the skewed sex ratio of science
In the journals Plata G., C.S. Henry, and D. Vitkup. 2014. Long-term phenotypic evolution of bacteria. Nature. doi: 10.1038/nature13827. Overall, bacterial phenotypic evolution can be described by a two-stage process with a rapid initial phenotypic diversification followed by a slow … Continue reading →

9:15 AM | A week of links
Links this week: A good Jared Diamond interview. The 10,000 hours rule – the best you can do is find the peak of your own ability. Tinder works because a picture is “worth that fabled thousand words, but your actual words are worth… almost nothing”. (HT: Razib) Dumb incentives, although economists would be the first to point […]

5:29 AM | Wooster’s Fossils of the Week: Upper Carboniferous seed casts from northeastern Ohio
We haven’t had a paleobotanical fossil of the week for awhile, so here are a couple of nice seed casts from the Upper Carboniferous Massillon Sandstone exposed near Youngstown, Ohio. They fall within the “form genus” Trigonocarpus Brongniart 1828. A form taxon is one that may not have any systematic or evolutionary validity, but it […]

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 […]

3:05 PM | One more thing to worry about
That's just swell! The universe could end any time, although the odds are rather low really, but still what a thing to stay awake at night worrying about. After figuring out that the universe was expanding, cosmologists wondered if the universe would end in a Big Crunch, sort of a reverse of the Big Bang, or in a Big Chill, expanding outward forever.  Then the discovery, sort of, of Dark Energy suggested that the universe would end in some sort of particle decay, a Big Rip, something that […]

7:09 AM | Chaos In The Church
Pope Francis has been continuing his campaign of liberalization within the Roman Catholic Church. At the recent synod on the family, reform-minded bishops within the Church, many installed by Francis, proposed language that, while not changing doctrine, would have liberalized the Church’s stance toward homosexuals and divorced people. The paragraphs that are getting all the…

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 […]

5:33 PM | Golden rain and fall color
Fall color this year is varied and very good this year, but as always fleeting. The area immediately behind our house is under the canopy of two sugar maple trees, one large and one huge, and the light especially in the late afternoon is just perfused with a completely lovely golden glow. And as a bonus, the weather was warm enough to sit on the patio and enjoy the light with a glass of wine.  But then it started to rain, not water, not cats and dogs, not frogs, but leaves, and […]

2:31 PM | Very depressing trend - decline of collections based research
The decline in collections-based research at universities has been in decline for some time as hiring decisions attempted to track newer, shinier, more fundable areas of biology. We used to say that collections-based research would only persist in museums and botanical gardens, but obviously that isn't so any longer. This is of course very short sighted, but that is actually the nature of science these days. Legislators no longer understand the need or value of basic research, […]

Biology concepts – Protista, taxonomy, phylum, kingdom, monophyletic, paraphyletic, cladistics, algae, diatom, dinoflagellateEuglena gracilis is an organism in the Kingdom Protista. It has one long flagellar undulipodium, but it can also move by amoeboid movement. It has chloroplasts and can do photosynthesis, but it also can eat other organisms. Is it any wonder that classifying protists is so hard?Classifying living organisms is self-perpetuating job. Imagine if the dentist sold candy […]

The French writer Alexadre Dumas Sr., who had traveled to Caucasus in the years of 1858 and 1859, was telling in his traveling diary that the best gift that the Georgian and Lezghian youth could give to their fiancées were the chopped hands of the individuals from the neighboring tribe.

8:41 PM | Epic battle of wills
An epic battle of wills is shaping up here in the Phactor household.  Mrs. Phactor purchased a small throw rug to place at the bottom of the stairs leading to our basement. Every time she goes by she says, "Who crumpled up this rug?" And she straightens it. Every time a certain cat goes by, she says, "Who straightened out my play rug?" And she crumples it up to her liking. Some things are just more interesting in 3D than 2D. Note the milk bottle ring, always a favorite cat toy. Thousands […]

4:03 PM | A message from Martha by Mark Avery | review | @GrrlScientist
This absorbing book is an engaging and wistful, yet measured, chronicle about the tragic loss of one very special, iconic, species, the passenger pigeon. This is the year of the passenger pigeon. Despite this, you might wonder how three books about the passenger pigeon could possibly have been published this year -- and, iconic or not, what more could possibly be said about an extinct species one hundred years on? Yet each book brings something new to the table. But my favourite of this trio […]

2:17 PM | How to teach yourself about an obscure snake
This article will soon become available in SpanishThe world is full of obscure snakes. According to Darren Naish at Tetrapod Zoology, the more you know about them, the better a person you are. Writing this blog, and in my research, I am often confronted with the challenging task of finding out something - anything at all - about a species of snake that I've never heard of before. This post is a walk-through of the process that I usually use to track down even the most basic information […]

1:47 AM | An invasive species drives rapid evolution in a native
 Anolis carolinensis male, dewlapping. Photo by Ambika Kamath.In 1959, W.L. Brown and E.O. Wilson proposed the following eco-evolutionary process: two closely-related species come into contact, interact strongly (usually over food and other resources), and thereby experience natural selection to diverge from one another--ecology influences evolution. Then, if such divergence resulted in sufficient resource partitioning, the species’ population dynamics would stabilize and the two (or […]
