Cortical area instability–experiments in monkeys 

On the instability (plasticity?) of cortical areas, just got reminded of this classic work:

"Somatosensory cortical map changes following digit amputation in adult monkeys", Merzenich et al. 1984 onlinelibrary.wiley.com/doi/ab

I want to tell you the story of Vivienne Malone-Mayes, Texas-born mathemetician and professor, but I don't think you can understand her journey without talking about the #AcademicRacism in which she existed.

Job post 

We are hiring an editor!

Do you have a background in ecology or evolution, and want to be involved in a broader range of topics than your own research area?

We are particularly keen to extend the geographical representation of our editorial team (see some possible locations in the job ad below).

“Exercise increases information content and affects long-term stability of hippocampal place codes” in mice. But the implications are tantalising.

Rechavi et al. 2022 doi.org/10.1016/j.celrep.2022.

This hard finding stands out: runners showed increased neurogenesis in their hippocampus.

“To assess the levels of hippocampal neurogenesis, we injected mice with Bromodeoxyuridine (BrdU), a marker for proliferating cells. In accordance with previous results (van Praag et al., 1999b), we found a higher number of BrdU-positive cells and increased labeling density of doublecortin (DCX), a protein transiently expressed in newborn neurons, in the DG of runners (Figures 1B–1D). This increase in adult neurogenesis indicates that physical activity affected the physiology of hippocampal circuits in our experiments.”

#behavioural time-scale #synaptic #plasticity was discovered by Bittner and Magee a few years ago: science.org/doi/full/10.1126/s

It was mysterious - how could the time-window for plasticity be so large?

This new paper from the Losonczy lab suggests that it's due to intracellular calcium release from the ER:

#introduction 🤓

I am a physicist specialized in #fluiddynamics and #solidmechanics with experience in #interdisciplinary research and #neuroscience. I develop modelling tools to predict #fluidstructure interactions in the #brain.

My research focuses on the role of intracranial vessel pulsation in #neurodegenerative diseases. I am highlighting how measurements of intracranial fluid dynamics combined with #biomechanics modelling can help to better understand and characterize brain #ageing.

Hi #ScienceMastodon!

My name is Meike and I am a postdoc studying cerebellar development and its role in neurodevelopmental movement and affective disorders.

Looking forward to meeting you and learning about your cool work!

Follow me for stories about and pretty pictures of the cerebellum.

🚨 BIG EXOPLANET NEWS! 🚨

Our team has released FIVE papers today on the most COMPREHENSIVE study of an #exoplanet atmosphere to date!

Using #JWST we obtained four transit observations of #WASP-39b early in the telescope's operations to study both the planet itself, and the telescope's capabilities to observe exoplanet atmospheres.

We detected numerous molecules in the planet's atmosphere, including CO2, CO, H2O, and SO2 🧵

The future is here! ⭐ 🪐 🔭 #Astrodon #Science

‘Eat local’ is a common recommendation to reduce the carbon footprint of your diet.

But transportation makes up a very small amount of the greenhouse gas emissions from food.

*What* you eat is far more important than *where* your food traveled from.

Defining brain functions is a top-4 challenge for brain research. Conversations with my co-author @amygdaloid have made me realize why. Among the big topics, I suspect that it's the most underappreciated.

Why does it matter? We summarize it here (share link):

Today I will blow your mind. 🙂

Most entomologists refer to bees as vegetarian wasps, as bees evolved from carnivorous wasps about 120 million years ago.

But did you know that there exist species of Vegetarian Wasps called Pollen Wasps - Pic 1 (Wikipedia), and Carnivorous Bees called Carrion Bees - Pic 2 (Ricardo Ayala)?

The wasps don't have pollen carrying hairs so they eat the pollen and regurgitate it at the nest.

The bees have special gut bacteria to digest meat.

We are excited about the below pull request from @TandonSuyash & team at @AMD, with a #HIP implementation for #RELION, which allows running it on @AMD #GPUs! If this works well, it will become part of #RELION-4.1. 😍

After scoping out Mastodon for about a week now, it's probably time for an #introduction

Hi I'm Alex, a Reviews #Editor for @Dev_journal, a community #journal covering #devbio, #stemcells & #regeneration. Development hosts the #devbiol community blog @the_node and is published by the @Co_Biologists.

I'll mostly be tooting about amazing #devbio research and conferences, and occasionally about personal stuff like #books, #reading, #gardening and other adventures on my bike or #kayak.

If you are submitting an abstract to
@CosyneMeeting
this year, especially if its your first time, we at the COSYNE DEIA committee have made this video to help you out: youtu.be/0r4Nz7NGmUw

Its interviews from experienced reviewers talking about how they evaluate abstracts

The distribution map of the hoverfly Eristalis pertinax may be telling a story about failed clean water regulations:

“Eristalis pertinax is a European hoverfly. Like Eristalis tenax, the larva of E. pertinax is a rat-tailed maggot and lives in drainage ditches, pools around manure piles, sewage, and similar places containing water badly polluted with organic matter.” inaturalist.org/taxa/52490?loc

Caveats: sampling bias, and unknown distribution prior to modern waterways pollution.

#introduction. I am a plant developmental geneticist. The lab addresses a fundamental biological question: how does morphogenesis translate genotype into form? To this end we study signaling at the plasma membrane - cell wall interface and we investigate how mechanical forces influence tissue shape using 3D digital ovules.
