We've learned more about #whalesharks in the last decade than all the preceding years combined, so by way of #DecadeinReview, here's my take on some of the key developments (a thread)
A quick squizz at #GoogleScholar shows 1,690 entries for Rhincodon typus (the scientific name of whale shark) before 2010, and 3,800 entries since. I know there's a big date bias in GS, but little doubt that it's been a huge decade for WS #science
One of the Big Things that emerged was the phenomenon of whale shark *aggregations*, or as we like to think of them, *constellations*. The biggest known to science, >400 animals at once, was described in 2011 journals.plos.org/plosone/articl…

Absolutely--huge shoutout to #JanetBrowne, whose work informed "Through Darwin's Eyes" sections of Consider the Platypus.

A lot of folks ask if Darwin is still relevant to this conversation... Short answer: 100%. He's the reason for the season. (More on this later in the week.)
So enough about ME. Let's talk about #Darwin.
We're learning more about evolution every day, with every fossil we find, every genome we sequence. A lot of new knowledge prompts people to ask whether Darwin was "wrong." @KingOfUniverse8 asked me this yesterday:

Controlling the speed and trajectory of evolution with counterdiabatic driving -- a TWEETORIAL 0/n #evolution #mathonco #mathevo #physics #quantumcomputing biorxiv.org/content/10.110…
#Evolution is the most fundamental biological *mechanism - and drives change over time across all the kingdoms of life. We are getting better and better at *predicting* its outcomes, and *harnessing it* (directed evolution), but we haven't previously had any *control* over it 1/n
in work w\ @D4N__ we took advantage of sequential application of selective pressures in a math model to *steer evolution* & relied on taking limits (as time -> infinity) to understand where populations equilibrated in genotype space 2/n journals.plos.org/ploscompbiol/a… @PLOSCompBiol

1. For our 7th “2C: Beyond the Limit” piece, @maxbearak and @vanhoutenphoto visited Angola, and found a gut-wrenching story about a town that's contributed virtually nothing to climate change – but is being targeted with eerie precision nonetheless.
washingtonpost.com/graphics/2019/…
2. Meet Tombwa, Angola, built on fishing. It sits onshore of a crucial oceanic juncture where the Benguela Current, traveling up from southern waters along Africa’s southwest coast, has traditionally delivered nutrient rich, cool waters through a process called upwelling.
3. That made this an ideal place for fishing – and that is still what the town of 50,000 runs on. For now.

During the Lightning Conference 2019 in Berlin, I had the pleasure to sit down with Adam Back (cyberpunk, cryptographer, PhD in computer science, CEO/Co-Founder of Blockstream etc.) for an interview.
Adam´s works (#Hashcash used in #Bitcoin #Mining) is cited in the White Paper of #SatoshiNakomoto.
Our fascinating talk deep down the Bitcoin Rabbit Hole covers a spectrum of questions and topics:

"Information theory, predictability, and the emergence of complex life"

SFI Seminar by Luis F Seoane of @IFISC_mallorca, streaming now:
"The size of the #environment in some ways captures the #complexity...longer words take longer and longer to sample. This means in smaller environments, smaller words mean more."

- Luís Seoane of @IFISC_mallorca on #information right now:

"More-complex bit guessers are going to survive in a wider variety of environments. But a more-complex guesser is going to pay a higher metabolic cost."

It’s #Croctober, so that means I’ll be featuring croc-relatives using the hashtag #AtoZcrocs. Follow along this month for a deep dive into how weird croc #evolution really got.
A is for Anatosuchus, a notosuchian from the Cretaceous of Niger. It’s name means “duck-crocodile,” for it’s oddly flared snout. #Croctober #AtoZcrocs #fossils

📸 Sereno and Larsson, 2009: doc.rero.ch/record/200234/… skeleton of Anatosuchus, flared snout to the left, body out to the right, missing most of its tailArtist's reconstruction of Anatosuchus in an upright posture, duck-like snout gaping to show off flared shape
Anatosuchus’ upright limb posture and funky snout might have helped it wade in the shallows and root around for small prey. #Croctober #AtoZcrocs #fossils

📸 Sereno and Larsson, 2009: doc.rero.ch/record/200234/… Photographs of Anatosuchus' skull in dorsal, ventral, and lateral views, snout flares out like a duck bill, but is filled with relatively small teethLine drawing interpretation of the skull shown in similar views as the photographs, snout flares out like a duck bill, but is filled with relatively small teeth

Happy to be back in Sweden for my 2nd #BiologyofSperm meeting & hearing fascinating stories on evolution of sperm, gamete interactions, reproductive organs and strategies by fellow #spermnerds
#BoS2019 #BoS15
Started strong yesterday with Sabine Koelle showing us the very first live imaging movies of sperm behavior in human reproductive tracts, all the way to the fertilization site, and even sperm filmed live swimming inside the testes! What a cool talk!
Next @lross_evoento told us about (incomplete) paternal genome silencing in fascinating mealybugs. @emwhitti brought us to the amazing world of Post-Ejaculatory Modifications w/ impressive proteomics data from 1000s of #drosophila reproductive tract dissections. #BoS2019 #BoS15

"You don't see radio changing gradually and suddenly become radar. #Darwin's theory doesn't work for #technology, and we have to make a new observation."

"Novel technologies are constructed from existing technologies. These offer themselves as components for the construction of further technologies."

Unlike the two-parent #inheritance typical to (but not ubiquitous among) #complex organisms, #technology inherits features from n parents - a "vast ancestral #network" more like horizontal gene transfer networks in #bacteria.

Statistics show that there will be a higher number of human living in the cities / urban in the coming years compared to rural. The enhancement of rural-urban migration flows impacts on the enhancement of the urban population.
It takes more efforts now to fulfil the food demand. That is one of the reasons why we at VFarm thinks that urban agriculture movement could be one of the most important movement today.
Let's hear what Rohit Kumar of Good Inc has to say:

"Life did not invent #DNA."

Experimental support for the #hotsprings hypothesis for life's origin: David Deamer of @ucsc on nucleic acid polymerization in the wet-dry cycling of Darwin's "warm little pond," powered by #geothermal. Lab results confirmed in #hydrothermal pools.
From "boring statistical partitioning" in the fission of early protocells to the complex #homeostasis-driven #mitosis of the cells we know - Doron Lancet of @WeizmannInstSci on the gradient between closure of #autocatalysis #networks to complex regulatory mechanisms of #biology.
"Life is an integrated nested network of dynamic #kinetic cycles."

Addy Pross emphasizes the importance of motion to the persistent forms of self-organizing #complexsystems at SFI today

"Most of the things that differ from the past will shortly die. The more they differ, the sooner they will die."

@SimonDeDeo of SFI & @CarnegieMellon on the linear correlation of #novelty & #transience - aka, "Why you mostly listen to the same songs over and over" - at #CSSS19:
"It's true that new things die. It's also true that is you want to be very very big, be new."

@SimonDeDeo of SFI & @CarnegieMellon on successful #novelty & hopeful #monsters in #evolution, #innovation, & #investment - aka, "Either be really boring, or be Beethoven" - at #CSSS19:
"#Revolutions are not just about ideas, they're about #information management. You can't just run a #revolution in a seminar room."

"The stranger your speech is, the more likely people are to just nod & move on."

"If you talk about #intelligence and #stupidity, you talk about #communication and #policy. That is the natural place to start."

Let’s talk about #Evolution. We’ve all had that dispute with a #Creationist that uses any desperate measure to attempt to prove intelligent design over Evolution.

There are modern day examples of how Evolution works and I will explore several of them.
Part 1: Human Evolution

Vestigial traits are examples of leftover muscles that Evolution has kept in some humans. Everyone knows someone who can move their ears, but can you? These muscles are auricle & are found in Dogs/Cats & are used to direct ears towards sounds.
The human brain is shrinking, and one theory suggests that a smaller brain is more efficient, and is gradually being rewired to work faster & take up less room. Is the brain shrinking to solve problems, and inhibit violent traits?

#kzoo2019 well @WestPoint_USMA were so anxious to talk, they just started on their own at 1328 sharp! Prof Rogers explains his cadets' "mission control center" or laboratory for #Military #History, working 8+ hrs/day on #medieval chronicles' paleography to #data mine 100yrs' war
Specifically looking for artillery information in skirmishes and sieges, to find what on the "laundry list" of sieges leads to #failure vs #success according to the #Database the cadets @WestPoint_USMA built collaboratively for the late #medieval & early #Renaissance. #kzoo2019
A small sample of the +90,000 #data entries - first up is Cadet Liam Kane with his findings on waging war by sieges vs by battles... taking #medieval #Military #History from generalizations to specifically-defined quantities... 47 battles to 134 sieges! #kzoo2019

It's all @kelvy_bird 's fault, haha ! Her book made me try to map a four-fold unified evolutionary scene: the #evolution of Life, means, ends & the #sustainability discipline/#metrics. Yes, I know it needs to be improved. #generativescribing in Plato's cave
@kelvy_bird LEFT: Let me explain what came to my mind, while trying to draw this . The left side obviously is about #Spirit, #God or the #Creator and it was @TimFreke who made me aware that we are now entering a next evolutionary stage: the development & story of #soul.
@kelvy_bird @TimFreke UPPER: For me it's a #Maturity Model of #Stewardship for our vital #capital resources. With our egoistic human nature, we depleted (as usual) our capital resources. #Sustainability marked the barrier in context & #Regeneration is all about (re)paying our debt

Ready for tomorrow and my first sessions of @SkypeScientist ! Looking forward to chatting, not with 1 , but 6 classes of middleschoolers! Send all the good vibes (and waves) my way for a good internet connection all day!

#scicomm #outreach
The morning started well with 2 different sessions with 2 classes of 7th graders from North Carolina @chowan_middle . Getting really cool questions about how it is to be a #scientist , why I chose to do what I do and how much I get to decide what I study.

FIRST UP: #8 seed Springhare (Rodentia: Pedetes capanesis) vs #9 seed Jackrabbit (Lagomorpha: Lepus californicus) #2019MMM
Why are these 2 species in the Jump Jump division? They're highly adapted for saltatorial, or jumping, locomotion. In fact, Springhares belong to the rodent family Pedetidae, which is Greek for "leaper or dancer" #2019MMM
Although rodents & lagomorphs are closely related (last shared a common ancestor ~80 million years ago; timetree.org), the adaptations that Springhares & Jackrabbits have for jumping evolved independently #2019MMM

The water in the pipeline cannot fix the leaks. Contrary to the advice #WomenInSTEM & #POCinSTEM receive, we cannot actually #leanin to solving the problem of #genderbias & #racialbias in #STEM & #academia. Thanks to @NatureEcoEvo & @RoinnAnLuisigh for this chance to say this. 1/
A few months ago, @Nature published a piece with advice on how senior women can confront #genderbias. While the advice contained therein was useful, the title was enraging. nature.com/articles/d4158…. 2/
It led me to rage tweet a thread of statistics on #genderbias in #STEM, and that thread blew up And then I got incredibly lucky when @RoinnAnLuisigh offered me the opportunity to turn it into a column. Working with her was AMAZING! 1000% fantastic 3/
