The government is saying that violence rules. That snatching foreign leaders and territories, and shooting US citizens in their cars at point blank range, is justified. That resistance is not only futile, it is dangerous. They can say these things. But they cannot force us to believe them.

This is so spot on. It's not possible to be creative and afraid/anxious at the same time, and to do great science we need that creativity

Honestly, one of the worst parts of the scientific funding crisis is having to spend so much time writing papers, proposals, etc. in a state of fear. I don't do my best writing while afraid, let alone my best science!

PSA to aspiring graduate students: If you have a submitted or pre-printed publication, **please** list it on your CV, mention it in your research statement, and in the application. Don't leave out the one thing that can make your application automatically higher ranking! #GradSchool Pls RT

On the cover: The cover image captures how a humble byproduct of the dairy industry becomes the foundation for a next-generation biomaterial in the work of Correa et al. Inspired by the saying β€œdon’t cry over spilled milk,” the artwork depicts milk spilling from a carafe, with its droplets spontaneously capturing and linking polymer strands to form an intricate network in mid-air. This visual metaphor represents the study’s central theme: transforming yogurt whey-derived extracellular vesicles into dynamic crosslinkers that create injectable hydrogels with regenerative functionality.

I only rarely get to blend my art with my science, which is why I am happy that my illustration for our lab’s first paper is out today as the cover of Matter @cp-matter.bsky.social!

I am so thankful for this reporting, it has been so hard to explain to non-scientists how these changes have impacted us and this does a great job.

each year around this time I wonder the same thing - why is there not a common app system for grad school? It takes literally hundreds of individual uploads given that students are applying to 10+ programs a cycle now.

In a new phase 3 trial, people randomly assigned to receive a flu shot made with modified mRNA were 34.5% less likely to be diagnosed with an influenza-like illness than people given a standard flu shot made with inactivated virus.

We need to stop the anti-science attacks against mRNA vaccines!

Coral die-off marks Earth's first climate
'tipping point', scientists say

A surge in global temperatures has caused widespread bleaching and death of warm-water corals around the world.

nature NEWS 12 October 2025 Coral die-off marks Earth's first climate 'tipping point', scientists say A surge in global temperatures has caused widespread bleaching and death of warm-water corals around the world. By Jeff Tollefson

Warming waters cause corals to β€œbleach” when these organisms expel symbiotic algae that provide nutrients, oxygen & vibrant colors.

The latest global bleaching event - researchers estimate >84% of the planet's coral ecosystems have been affected since Jan 2023 - has made it clear the crisis is now.

Enkephalin-producing regulatory T cells in the skin restrain local inflammation through control of nociception Regulatory T cells curb noxious sensory signaling to dampen cutaneous inflammation, a neuromodulatory mechanism for immunosuppression.

'Our results indicate that a population of Treg cells acts to oppose excessive activation of sensory neurons through the production of enkephalins, endogenous opioid peptides that reduce nociceptive signaling, & by limiting its tone to restrain associated inflammation during inflammatory challenge'

Quantitative imaging of lipid transport in mammalian cells Nature - Directional, non-vesicular lipid transport is responsible for fast, species-selective lipid sorting into organelle membranes.

big one! a decade in the making. nadler & team develop tools to track lipid transport in living cells at single-species resolution. turns out non-vesicular, asymmetry-driven transport is the main architect of organelle identity. feels like the dawn of a golden era for lipid biology. rdcu.be/eBGJv

We explored whether extracellular vesicles (EVs) could serve as structural elements in biomaterialsβ€”and whether doing so would confer intrinsic bioactivity.

Artemis' thread explains how we used yogurt EVs to answer both these questions! πŸ§ͺ
