Shhh

Massively parallel interrogation of the fitness of natural variants in ancient signaling pathways reveals pervasive local adaptation The nature of standing genetic variation remains a central debate in population genetics, with differing perspectives on whether common variants are almost always neutral as suggested by neutral and n...

One of the most exciting works of my career, years in the making. We used high-throughput precision genome editing to test the fitness effects of thousands of natural variants. Our findings challenge the long-held assumption that common variants are inconsequential.

I had an amazing visit to @embl.org’s Rome/Monterotondo site, thanks @jamiehackett.bsky.social for hosting!

Declining ocean greenness and phytoplankton blooms in low to mid-latitudes under a warming climate Chlorophyll a is declining in low- to mid-latitude oceans, indicating reduced ocean productivity and fewer phytoplankton blooms.

🧪 Please share!: My lab is currently recruiting graduate students (RAs and TAs) this cycle to start Fall 2026.

Howard University Graduate School early application deadline is 11/15/25 (to be considered for certain fellowships). We have additional deadlines in the spring (Feb/April) 1/n

For the literature search, not the experiment design. I like coming up with my own stupid experiments

I’m intrigued, gonna give this one a shot. We don’t have to treat it any different from a souped up version of the Microsoft paperclippy thing

Skeptical but since you’re saying it, I will give it a shot!

On an Arctic archipelago, frozen soil may preserve a hidden history of viruses Scientists are hunting for ancient RNA in Svalbard’s permafrost, hoping to shed light on the evolution of viral diseases

I am fascinated by how viruses evolve - and not just since #SARSCoV2 has shown us at the global stage how consequential virus evolution can be for us.
In my new story in @science.org I got to explore how researchers are probing deeper into the past with old RNA virus genome.
So a 🧪 thread…

Antiviral reverse transcriptases reveal the evolutionary origin of telomerase Defense-associated reverse transcriptases (DRTs) employ diverse and distinctive mechanisms of cDNA synthesis to protect bacteria against viral infection. However, much of DRT family diversity remains ...

1/10 Genome maintenance by telomerase is a fundamental process in nearly all eukaryotes. But where does it come from?

Today, we report the discovery of telomerase homologs in a family of antiviral RTs, revealing an unexpected evolutionary origin in bacteria.

Wage war on nature to build new homes: that’s Labour’s offer, but it’s a con trick | George Monbiot The government’s new planning bill is tearing down environmental protections to benefit developers. This nation of nature lovers won’t stand for it, says Guardian columnist George Monbiot

Today's column is about the government's huge, unprecedented assault on nature ... and about the eerie, astonishing silence of the big nature groups. The RSPB, National Trust, Wildlife Trusts have 7.5m members between them. A vast force, completely unmobilised. 🧵

Today my @nytimes.com colleagues and I are launching a new series called Lost Science. We interview US scientists who can no longer discover something new about our world, thanks to this year‘s cuts. Here is my first interview with a scientist who studied bees and fires. Gift link: nyti.ms/3IWXbiE

Accepted version of our article "Half of microbial eukaryote literature focuses on only twelve human parasites" now out in ISMEJ!

Awesome effort led by undergrad Joanna Lepper and with @hbrappap.bsky.social.

Day 1 at #EESImaging 🤩 Exciting start to the EMBO | EMBL Symposium 'Seeing is believing: imaging the molecular processes of life' – diving into cutting-edge imaging technologies 🔬✨

Looking forward to an inspiring few days of science, discussion, and discovery!

Book cover of "The Riddle of Organismal Agency: New Historical and Philosophical Reflections" (Routledge, 2024). The book belongs to the "History and Philosophy of Biology" series. The editors are Alejandro Fábregas-Tejeda, Jan Baedke, Guido I. Prieto, and Gregory Radick. The design features a geometric pattern of interlocking, multicolored triangles and rectangular prisms in shades of red, yellow, teal, white, and pink. The Routledge logo appears in the lower right corner.

Still puzzled by the debate on organismal agency? Our edited collection brings historians, philosophers, and scientists into dialogue—offering a wide array of perspectives. An affordable paperback edition will be out at the end of the month! www.routledge.com/The-Riddle-o... #HPS #evobio #philsky
