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 “don’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!

We're so proud of this work, so in case you missed it, please check the paper out here: www.cell.com/matter/fullt...

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.

Chart: Relative Vaccine Efficacy (Primary End Point).

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!

Come! I'll be part of a little panel talking about queer nature and the tickets are free!

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 “bleach” 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'

Tuning collagen nonlinear mechanics with interpenetrating networks drives adaptive cellular phenotypes in three dimensions This work demonstrates that changes in the nonlinear elasticity of collagen in hybrid networks tunes cell-matrix interactions.

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

Yeah, because they've been hacking away at the social safety net since the year I was born (it is actually the year I was born quality of life started to decrease it's pretty depressing)

Extracellular vesicles as dynamic crosslinkers for bioactive injectable hydrogels Extracellular vesicles (EVs) offer potent biological functionality but are challenging to integrate into materials. Using scalable EVs from yogurt whey, the authors define key parameters for forming E...

Here is a link to the paper www.cell.com/matter/fullt...

The lab's first paper is out now in @cp-matter.bsky.social

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

Artemis' thread explains how we used yogurt EVs to answer both these questions! 🧪

Are you from one of these states? Then we need your help to save American science!

The Senate Appropriations Committee will be marking up the President's Budget Request for science on Wednesday. People have been saying the proposed cuts "decimated" US science, but that's wrong: they are apocalyptic

Thanks Jessica! Hope you're doing well

Thanks John!

I'm honored to join the amazing community of Beckman researchers! I want to thank all the mentors and friends who helped me reach this milestone -- it's too many to list!! This funding will support our work integrating synthetic and natural nanomaterials to develop new cancer immunotherapies

"Women are PIs on 58% of the canceled grants, although they are PIs on only 34% of all active NSF grants.

Similarly, Blacks are PIs on 17% of the terminated grants, although they make only 4% of the total pool. Hispanic PIs and those with disabilities were twice as likely to lose a grant."

This is a project and an area I've been working in for years. We've published numerous papers on the topic, and recently went through a competitive renewal in which the science of the grant was rigorously evaluated and supported.

And it was cut for cheap political points

A screenshot of the termination notice with "This award is terminated effective the date of this award, due to unsafe antisemitic actions that suggest the institution lacks concern for the safety and wellbeing of Jewish students." highlighted

Yesterday, the NIH R35 “Outstanding Investigator” grant to fund scientists in my lab studying antibiotic resistance was terminated for reasons not related to the content of the science, or any actions taken by me or members of my lab

Vaccine research is out. Cancer research is out. How are immuno engineers thinking about what role federal funding can now play in this work? Is there any facet of our field that hasn't become villainized? 🧪

One of the few powers we have as individual citizens, particularly between elections, is our consumer power. Effective boycotts could really make a difference, and I'd love to see guides for the top 5 companies to boycott. I for one cancelled Prime today and closed my Amazon credit card.

The Trump NIH is banning hires of new students and postdocs. This is devastating for NIH research and will result in a lost generation of researchers at the institution.

Heard from a applicant today: "A lot of people are banking their entire careers on the [NIH student programs]..."
