Just published 3rd in a trilogy of #spierslab reviews (pandemic years) each exploring brain regions in navigation:
2020: #Striatum & #Hippocampus (wth @cgahnstrom)
2021 #Prefrontal Cortex (wth @ZitaPatai)
2022 #HippocampalFormation (wth @NilsNyberg_ @ElDuvelle @caswellcaswell)
Our latest 2022 review "Spatial goal coding in the hippocampal formation" explores how the hippocampal formation (e.g. hippocampus, subiculum, entorhinal cortex) might code information for navigational guidance. Current #OA version available here:…
The 1st author of our review @NilsNyberg_ did an amazing job thoroughly reviewing the literature. Its the most detailed review I've ever had the chance to write. Kudos to @NeuroCellPress for supporting such in depth reviews, allowing 310 references!

#Azhdarchids, a brief thread concentrating on my involvement with this amazing group of #pterosaurs. Azhdarchids have to be regarded as the most distinctive and unusual of pterosaur groups, and views on how they might have lived have varied considerably... (images by @MarkWitton)
In 2008, @MarkWitton and I examined the skeletal proportions, cranial anatomy and sedimentological setting of #azhdarchids and concluded that they were strongly adapted for quadrupedal walking in terrestrial settings....
They were likely striding predators of small and mid-sized prey, analogous to ground hornbills. We termed this the ‘terrestrial stalking’ model. See our #OA @PLOSONE paper A Reappraisal of Azhdarchid Pterosaur Functional Morphology and Paleoecology… cont...

New in @nature w/ @philvlam, @csugimoto + @lariviev:

The article has 2 main parts:

1) We chronicle rebranding + bootlegging as new predatory publishing tactics.

2) We argue that open peer review is the best way to kill the Hydra of predatory journals.…
We focus on the case of OMICS International, the infamous predatory publisher who was recently slapped w/ a $50m USD fine for deceptive business practices (@FTC). OMICS is responding to this stigma by creating new journal brands. OMICS goes as far to 'retcon' old articles.
As a couple of examples, using the Wayback Machine to access the initial OMICS publications, here's OMICS erasing the OMICS branding in new 'Hilaris' and 'Longdom' brands. Using #OA publishing to retroactively alter the scholarly record is a disconcerting precedent.

This tiny crab trapped in 100-million-year-old amber is the most complete fossil crab ever discovered! But how did a crab get trapped in amber in the first place? Here we tell you the story… #Science #Evolution #SciComm 1/n Image
Transitions from marine to non-marine environments (e.g., land, brackish & freshwater) are an infrequent even in most animal groups. And yet, true crabs, or #Brachyura, have done it independently over a dozen times! #ocean #freshwater #evolution 2/n Mangrove tree crab, Aratus ...
Amber is like a time capsule that preserves organisms like frozen in time. While most fossils in amber are land-dwelling animals—principally insects—, aquatic organisms such as crabs are extremely rare! #amber #jurassicpark #Cretaceous #Crabs Photo by @LidaXing1982 3/n Image

Ich habe mich dazu entschieden, das Thema einer Wissenschaftskultur der Digitalität an den ~eigentlichen~ Beginn dieser Woche zu stellen. Das tue ich, weil ich überzeugt bin, dass wir die Möglichkeit haben, ein erweitertes Verständnis von akademischer communitas zu entwickeln. 1/
In einer Kultur der Digitalität (nach Stalder) zu leben, bedeutet, dass sich Transformationen und Verwerfungen von Formen des gesellschaftlichen Umgangs mit Wissen nicht erst andeuten, sondern ~bereits Realität~ sind. 2/
Damit stehen etablierte Prozesse der Wissensaneignung, der Hervorbringung und Kommunikation von Wissen sowie der Status von Wissen selbst zur Disposition. Die Frage, was Wissen sei, war noch nie so offen wie heute. Ein Rückzug auf eine vordigitale Kultur ist keine Option. 3/

Our new paper examines associations between specific antipsychotics and a wide range of crime outcomes, incl. arrests and convictions for violent and drug-related offences. Analyses data on all prescriptions 2006-13 in Sweden. Some novel findings. #OA:… 1/
First, the overall pattern emerges that antipsychotics are associated with clear reductions in all crime outcomes. Shown in between-individual models (crime rates in people dispensed meds vs those not dispensed meds) - among the persons who were prescribed antipsychotics 2/
Also found in within-individual models - where crime rates are compared within each individual (during periods on and off medication in the same person). Figure shows rate ratios adjusted for age and other meds (where less than 1 equates to risk reduction on antipsychotics) 3/

Announcing a world first! Our amazing interdisciplinary team has virtually unfolded and read an unopened letter from 1697 without breaking its seal, and officially launched #letterlocking as a field of study in Nature Communications.… #OA [going live today]
Like countless historic letters, it was sent using letterlocking - the process of folding and securing a writing substrate to become its own envelope. Our virtual unfolding process shows how this letter has been locked while preserving the packet intact for future study. 2/?
The letter is from one Jacques Sennacques, trying to chase up a legal document related to a death. The letter was never delivered. Come on, be a voyeur. You are among the first to read it in 300 years.

1/9 🚨New @Diversity_Turn paper on #tree🌳diversity and stand structure in the #vanilla landscape of northeastern #Madagascar🇲🇬 is finally out in @ApplVegSci
Check this thread for the main takeaways!
#OA paper:…
2/9 Madagascar harbors an exceptionally high diversity of endemic species, especially trees. Many of these species are restricted to the humid Northeast where smallholder vanilla agroforests shape the landscape and support local livelihoods
3/9 Tropical agroforestry has the potential to reconcile biodiversity conservation with production goals. However, agroforests differ in land-use history and this is often neglected in research and policy.

#Azhdarchid Revolution -- starting in 2008, @MarkWitton and I published a series of papers instigating a paradigm shift on the spectacular azhdarchid #pterosaurs. New data supports our model and it continues to evolve. Most of our papers on this are #OA. Thread... ImageImageImage
Our opening salvo was the 2008 @PLOSONE paper, which laid out the case for TERRESTRIAL STALKING as the primary way of life for these animals. At this point, our argument was that all #azhdarchids were - more or less! - alike in ecology and bauplan...… Image
Fieldwork in Romania (led by the late Matyas Vremir, who died earlier this year) led to the 2015 discovery that some #azhdarchids were proportionally 'thick-necked' and, furthermore, that niche partitioning was present in some faunas...… Image

Our new #IsleofWight #theropod #dinosaurs - Vectaerovenator (not as scary as it looks: 'vect-air-oh-ven-a-tor') from the Greensand of #Shanklin - was published yesterday in an #OA paper, available here:… Brief thread on this research...
This dinosaur - so far known from four extremely unusual, anatomically interesting vertebrae (two of them shown here) - was discovered by three different collectors, our work on describing them was led by University of Southampton PhD student @palaeoguy12 ... #FossilFriday Image
It was obvious from the start that this was (1) a theropod (or predatory dinosaur), (2) a new species and genus, and (3) interesting in being highly pneumatic (that is, it has loads of air-filled cavities and openings: you can see those features in these photos)... #dinosaurs Image

In normal times, connections between students on a college campus are an asset. During a pandemic, they are not.

My paper with Ben Cornwell on the structure of course enrollment networks @Cornell now out @SociologicalSci (#OA):…

I've tweeted about this paper before, but thought it'd be useful to update now that paper is peer-reviewed & published.

Teaser for regular readers: last tweets in today's thread reflect on findings in light of "reopening" conversation of last week+. 2/
Key findings: the average Cornell student shares courses with a max of 529 other students over a week of classes. (Actual will be lower, because attendance is not 100%.)

This increases to 600 students if just look at undergrads, because grad courses typically smaller. 3/

Oh my GOSH
1st new #Neanderthal skeleton in +20 years

This is BIG stuff: plenty of bits & pieces found in that time plus vital re-examination of old claimed burials, but what's been missing is a new mostly-complete find we can use 21stC methods on

[off to read paper]
Might tweet as I read 😁

But note: Shanidar is a tricky site and there's long been evidence of both potential intentional body deposits, AND natural rockfall as ways #Neanderthal bodies got into the ground.
Plus there's a lot of individuals but while some are close to each other spatially (and relative to unexcavated area of this humungous rockshelter, all are clustered in centre), they're not all from same period in time.

(1/21) Do you work with digitized manuscripts? I have 350 pages to help you out with that! "Among Digitized Manuscripts", published with @BrillPublishing. It’s out now! Download the book in open access here… More information:
(2/21) Manuscripts have been digitized in large numbers. Technology has become easy to learn. It is time to capitalize on these opportunities and accept ‘digital manuscript studies’ as a normal, yes necessary, part of our work. This book is a great start for that!
(3/21) It introduces a conceptual and practical toolbox for working with digitized manuscripts, starting with establishing a vocabulary to talk about the (quality of the) digital materiality of them and ending with explaining Python and OpenCV to do automated image analysis.

In veel gesprekken, praatjes, en bijeenkomsten met onderzoekers en staf bemerk ik nog regelmatig onbekendheid met #openaccess. Voor open toegang is men wel te porren, maar vooral het wat, hoe en waar is lang niet altijd duidelijk. Vandaar dit #openaccess draadje met tips:
Voor meer informatie over alles rond #openaccess (kleuren, vormen, modellen, etc.) wordt door @deVSNU @NWONieuws @SURF_NL en UKB de website onderhouden. Hier vind je ook meer informatie over de huidige landelijke #oa deals met grote uitgeverijen.
Op dit moment zijn er 14 landelijke #openaccess deals met onder andere @SpringerNature @WileyOpen @BrillPublishing @SAGEPublishers. Een overzicht vind je hier:…

Here are ten things I’ve changed my mind about in the last few years of being a scientist
1. P-values are bad.

Nope. P-values are good for what they’re designed to do. Just because they’re (often) misused doesn’t mean that we should abandon them.
2. Bayes factors will save us from the misuse of p-values

No. Bayes factors *can* be useful, but they’re not always the solution to p-value limitations.
