Transcriptional Interference Gates Monogenic Odorant Receptor Expression in Ants Communication is crucial to social life, and in ants, it is mediated primarily through olfaction. Ants have more odorant receptor (OR) genes than any other group of insects, generated through tandem d...

If you’re interested in ants, olfaction, gene regulation, or all of the above, here’s a new preprint from the lab for you. It describes an unorthodox mechanism of transcriptional interference by which ant olfactory sensory neurons produce a single functional receptor.

Strain variation identifies a neural substrate for behavioral evolution in Drosophila Sexual selection acts on heritable differences within species, driving the parallel diversification of signal production in one sex and behavioral responses in the other. This coevolution implies that...

Clearly amazing appearance around 888m in #MarDelPlataCanyon: Amphitretus sp. This telescope octopus has adapted to live in a place where there is nowhere to hide but in plain sight.

Do you know a young person with an interest in insects? 🦋

The Douglas Boyes Fund aims to provide people aged 14-18 with access to entomology equipment, fostering their passion for insects and inspiring them to engage and share their interest with other young individuals 🔽

“Why Are We Funding This?” Long-standing myths about “silly science” have contributed to the reckless slashing of government-supported research.

Silly-sounding science is what happens when researchers do exactly what they are supposed to do, which is thinking freely and exploring new ideas with wide-open curiosity. 🧪

Excited to share the lab's 1rst preprint! Rapid high-res immunofluorescence is now possible in cultured & environmental diatoms thanks to 4-fold expansion microscopy. A step-change for comparative cell biology in one of the most important phytoplankton groups on the planet 🥳

Barbara McClintock portrait

🧬🌽 Happy Transposon Day! 🌽🧬

Today we celebrate the birthday of Barbara McClintock - scientist extraordinaire and discoverer of jumping genes. Still the only woman to have an unshared Nobel Prize in the biomedical sciences #TransposonDay2025

Cuts have consequences, illustrated. As seen on TV 📺

My ongoing request:

If your NSF or NIH grant was terminated--whether at Harvard or elsewhere--please report it here.

NSF: grant-watch.us/submit-nsf.h...

NIH: grant-watch.us/submit-nih.h...

Our trackers are actively used in lawsuits and are often the only record that terminations ever occurred.

Guess how much of the ocean floor humans have explored Hint: it’s less than 1% — a lot less.

It's often said that we have mapped Mars better than the bottom of our oceans. A new study by @oceandiscleague.bsky.social has now quantified this: we have visually explored less than 0.001% of the deep seafloor, 1/10th the size of Belgium. My latest for @nature.com

Cuttlefish are known for dynamic, kaleidoscopic displays—and yet they seem to be colorblind. How does an animal that can't see color project color out onto its skin?

Just one of the enigmas discussed in our latest episode, w/ @tessamontague.bsky.social!

New episode!! 🎙️📣

A conversation w/ @tessamontague.bsky.social about cephalopod camouflage.

Cuttlefish and other cephalopods can change their appearance—color, pattern, texture—with lightning speed. What's going on in their skin and brains that makes this possible?

Opinion | Science Suffers With Trump’s Funding Freeze America’s scientific enterprise demands reliable stewardship, not destabilizing political intervention.

My father-in-law, Jack Strominger, and I wrote a letter to the @wsj.com editor about the current threats to science due to Trump's funding freeze. Please repost! www.wsj.com/opinion/scie...

Most People Buy a New Phone Every 2.5 Years. There’s a Better Way Back Market and iFixit are partnering to encourage consumers to keep their phones in service for at least five years—and to pressure manufacturers to extend smartphone support to 10 years.

Replacing the battery & using an iPhone 13 for 5 years rather than 2.5 could cut emissions 49%, "which could prevent 15.6 million tons of CO2 emissions per year." That's as much as a small country. www.wired.com/story/back-m...

Harvard University Harvard University is devoted to excellence in teaching, learning, and research, and to developing leaders who make a difference globally.

Harvard redid its whole homepage to push back against the administration’s demands. I mean, this is just a website but I think it’s kind of a great PR move: www.harvard.edu

I highly recommend this inspiring new book by Nahum Ulanovsky! A plea for neuroscientists to embrace “Natural Neuroscience”: use emerging technologies to uncover meaningful behavior and neural representations in free-roaming animals exposed to real-world stimuli.

She Worked in a Harvard Lab to Reverse Aging, Until ICE Jailed Her (Gift Article) President Trump’s immigration crackdown ensnared Kseniia Petrova, a scientist who fled Russia after protesting its invasion of Ukraine. She fears arrest if she is deported there.

The Americans are doing to Kseniia what the Russians did to Brittney Griner for having 0.7 grams of cannabis oil. Except no one is coming to negotiate her freedom and Harvard is sitting on their hands. I am so ashamed. Please share this story.

Published an op-ed for @cnn.com: “Nobel laureate: I owe America my success. Today, its scientific future is in danger.”
A personal reflection on what’s at stake as science funding gets slashed. I’d be grateful if you could amplify both in and beyond the science world.

The current figure I'm seeing is that as many as 3.3 million Americans protested today. #HandsOff #Resist

With its UFO-like display, the cuttlefish may look like it’s trying to get attention—but its intent is anything but.

The undulating black stripes confuse prey, making the creatures all but invisible to crabs and other victims: scim.ag/3FVL43z

What happened in Wisconsin is an example of what is most feared: That in a true democracy regular people have more power than a billionaire, that all the money in the world doesn’t change one person one vote.

A small orange king crab faces the camera. It has a large number of small blue dots on its shell.

I know it’s so annoying! Apparently it’s free, but you have to sign up for an account. I think my mum is the only one who was invested enough to do that.
And it blocks my favorite part - the students’ experimental ideas

Thank you to @gthomasbarlow.bsky.social for the great photo!

I'm thinking of our students and all the other incarcerated individuals who've been locked in their cells for weeks. I hope they can resume their undergraduate educations soon.

[4/4]

...the NY incarcerated population has been denied access to classes, the library & basic human rights (like showers) because of a strike by NY correctional officers wanting solitary confinement back (& other demands)

I believe education is a human right. It uplifts society & must be protected [3/4]
