1:00 PM | Sharkageddon may be the worst Shark Week show *ever*
Thursday night, I sat down with more than 15 scientists to watch Shark Week. Most of them don’t watch the annual spectacle—they’ve become embittered after years of Discovery’s fear mongering, mockumentaries, and lies. But this particular episode was different—it was all about our home, Hawaii. We all wondered how the sharks that roam our islands’ […]The post Sharkageddon may be the worst Shark Week show *ever* appeared first on Science Sushi.

10:27 AM | True facts about anglerfish | @GrrlScientist
To the female anglerfish, the human male is a very loud, annoying and unnecessarily complicated pair of gonads.Caturday has arrived once again, so it is time to watch some animals doing stuff! Today's caturday animal is the anglerfish, an ancient taxonomic order of bony fishes that arose sometime between 100 and 130 million years ago. (In contrast, humans are mere evolutionary babies, having appeared sometime between just 2 and 6 million years ago.)Anglerfishes got their name from their method […]

2:50 AM | From the Russian wilderness to the big city!
Guest Blogger: Sarah Frederick (’15) Arriving in Moscow was a sharp return to reality. Suddenly all of the things that had come to feel normal while we were in Kamchatka – the winding gravel roads and little towns with random meandering livestock that would peek in your windows – were replaced by traffic jams and […]

9:21 PM | How to conquer the world
Our species Homo sapiens has been around for some 200 000 years, and is generally thought to have evolved from older human species present in eastern and sub-Saharan Africa (University of Utah, 2005). But how did we come to be global (and even lunar) mammals? Debate still rages over how long ago H. sapiens left […]

3:19 PM | Problematic Humour In Academic Talks

2:07 PM | New Books Party: books received this week | @GrrlScientist
What good is a weekend without a good book to read? Take a look at these books -- hot off the presses -- that you may enjoy!When I get new books, I like to share them with people. Unfortunately, since you all are so far away, I cannot host a book party in my crib where you can look over them, so Ill do the next best thing. Ill host a book party on my blog each Friday of the week when I either purchase books, they are given to me or when review copies arrive in the mail. In this New Books Party, […]

2:01 PM | Botanical Geek Tour in Florence - Giardino dei Simplici
Chronological order is just so demanding, so let's back up a few days. Veronica (a very botanical name) works here at the villa and as a natural history student she recommended, once she discovered our botanical interests, that TPP visit the Giardino dei Simplici in the center of Florence. Florence is a lovely old city on the Arno River filled to the brim with Renaissance art and architecture that is presently under an assault by hordes of tourists.  And therein […]

2:01 PM | Today's YAMMM (Yet Another Mostly Male Meeting) Brought to You by CIFAR & NAS
Well, just got an invite to this meeting: Symbioses becoming permanent: The origins and evolutionary trajectories of organelles.  The topic seems of direct interest to what I work on.  And, it is relatively close (Irvine is a short hop away).  So this could be a way to go to a meeting without having to travel too far.  And maybe I could see my younger brother Matt who lives in LA and just graduated from UC Irvine's Masters program in Sound Engineering. Then I looked at […]

12:57 PM | Giardino di Villa Camberaia - Botanical Geek Tour adventures in Tuscany
Some guide book somewhere mentioned that the garden of the Villa Camberaia perched high in the hills above Florence as a great destination for garden lovers.  Well, you know the botanical geek tour squad will try their best to get the straight dope for our faithful readers. Without any particular agenda today, the villa's location was easily found on Via del Rosselino outside of the little town of Settignano. What better than a little botanical adventure a bit off the beaten […]

Last week I described a cyclostome bryozoan on the outside of a quartz cobble from the Faringdon Sponge Gravels (Lower Cretaceous, Upper Aptian) of south-central England near the town of Faringdon. This week I’m featuring a variety of heavily-bored calcareous cobbles from the same unit. One is shown above in its matrix of coarse gravel. […]

8:09 PM | Tear Gas: the chemical warfare agent used on demonstrators in Ferguson
The clash between police and protestors in Ferguson, Missouri has escalated significantly over the past few days. Police dogs and handguns have been swapped out for tanks and assault rifles. The protestors are being shot at with rubber bullets and wooden baton rounds, but perhaps the most disturbing images surfacing are those of police suppressing […]The post Tear Gas: the chemical warfare agent used on demonstrators in Ferguson appeared first on Science Sushi.

7:00 PM | An important read: Emma Pierson on gender and authorship position in science
This is a fascinating read: In Science, It Matters That Women Come Last | FiveThirtyEight.  By Emma Pierson, who works at 23 and me.  It has all sorts of references of use and details on authorship position in scientific publications and how gender and author position are correlated.  Definitely worth a read. -------- This is from the "Tree of Life Blog" of Jonathan Eisen, an evolutionary biologist and Open Access advocate at the University of California, Davis. For short […]

1:30 PM | Competition for ecological niches limits evolution of new species | @GrrlScientist
A recently published study finds that competition for ecological niches limits the evolution of new species. Further, this study finds that speciation rate slows or even stops as available ecological niches fill up. Why are there so many more species in some regions than in others? According to a recent study, competition for ecological niches limits the evolution of new species. Further, this study, which analysed the genetic and evolutionary relationships between all 461 species of Himalayan […]

12:00 PM | Antibiotic Resistance For Everyone!
Everyone should know what antibiotic resistance is.

10:25 AM | GPS - It helps, mostly.
GPS devices are handy little gadgets, up to a point, but still it's nice to have a really good map. So even with our trusty GPS guide the Phactors have made their share of wrong turns, but yesterday while threading our way through a little Tuscan hill town, the GPS said, "turn right here", and we did driving right up a dead-end alley. And there at the end of the alley, where in a classic example of good advise given way too late, was a sign, in English, that said, "Don't follow GPS".  Now […]

3:48 AM | Right beneath our feet: amazing nature in our backyards (Reign of Fire II?).
Our normal environs tend not to excite our scientific interest on a daily basis. They can instead become so familiar as to become boring and mundane – or just effectively invisible. We are instead more likely to be captivated and amazed when we go somewhere new – the Arctic, the Galapagos, the Amazon, the Negev Desert. On these trips, we tend to get excited about all sorts of critters, no matter how small or common. When visiting new countries, I find myself eagerly taking pictures […]

10:41 PM | The power of hand-held x-ray fluorescence analysis comes to Wooster
WOOSTER, OHIO–Dr. Meagen Pollock, our mineralogist-petrologist and instrument scientist extraordinaire, should be writing this post, but she was off campus during this event. It is left to the paleontologist, of all people, to file this report. Despite my technological naïveté and more biological than chemical orientation, I quite enjoyed myself. I certainly learned a lot. […]

Biology concepts – bacteria, climate, respiratory, birds, arthropods, astrobiology, cloudsCarl Sagan wasn’t just the host of the original Cosmoson TV. He solved the riddles of Venus’ high temperature, the seasons on Mars, and the color of Titan. He also wrote one of my favorite speculative fiction novels, Contact.

5:46 AM | Nutonian’s Eureqa and Concerns of Overfitting
I’ve been using Nutonian’s Eureqa symbolic regression product extensively since early 2013. Back in late 2013, there was an article about Nutonian’s Eureqa that elicited comments. An “A.E. Bartholomew” weighed in with a comment that the title, “Nutonian raises $4M to extract ‘laws of physics’ from data”, was “hyperbolic and misleading”. That led me to […]
