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, […]

1:04 PM | Bat signals: genomic traces of sensory rewiring
How does evolution rewire an animal’s sensory system? In time for both National Bat Week and Halloween, new research in G3 investigates this question by comparing the genomes of bat species that “see” the world in different ways. The black … Read More The post Bat signals: genomic traces of sensory rewiring appeared first on Genes to Genomes.

12:00 PM | Almost This Or Almost That? Must Be The Other
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. These hands, brought as trophies, […] The post Sex and power. The reproductive instinct of conquerors appeared first on Social Ethology.

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 […]

4:15 PM | Some suggestions for having diverse speakers at meetings
Been having a lot of discussions online in response to my post (Apparently, the National Academy of Sciences thinks only one sex is qualified to talk about alternatives to sex #YAMMM) tracking the awful gender ratio for speakers and session chairs at meetings run by the National Academy of Sciences in their Sackler series.  Some people were asking what one can do to improve gender diversity at meetings so I thought I would post this which I was meaning to do anyway […]

This is one of those mostly stupid www click bait lists, but inquiring minds just had to know.  Here they are in no particular order.  1. Grits – TPP finds them to be tasteless fodder. To be fair, other cultures have their versions of tasteless fodder too.  So don’t be too quick to point your spatzle/dumpling/yuca stained fingers at grits.  Actually TPP likes yucca better than grits.   2-3. Velveeta cheese/Cheese Whiz – Both of these were counted […]
