New study by Postdoc Rodrigo & Prof. Stephanie Pierce reveals surprising secrets of fishes brains!

The FAS Current sat down with Andrew Knoll, Fisher Research Professor of Natural History and Earth and Planetary Sciences Emeritus, to discuss his new book “Earth and Life: A Four Billion Year Conversation” on the 4-billion-year “conversation” between Earth and life.

Meet Megachelicerax cousteaui, a 500myo sea predator that just rewrote the evolutionary history of chelicerates by 20 million years! New study in @nature.com by @cambrianlife.bsky.social Dr. Rudy Lerosey-Aubril and Prof. Javier Ortega-Hernandez

An exciting new study in PNAS led by postdoc Andrea Unzueta Martinez and Prof. @pgirguis.bsky.social lab shows that oysters coordinate with microbes living inside of them to build their hard shells! A game changer for understanding ocean resilience as waters become more acidic from #climatechange

Wendy Valencia Montoya Receives Weintraub Graduate Student Award for Groundbreaking Thesis on the Evolution of Sensory Worlds 🧠 🧪🧬 #AcademicSky #higherEd www.mcb.harvard.edu/department/n... @nbellono.bsky.social @rachellegaudet.bsky.social @basicsci.fredhutch.org @harvardoeb.bsky.social

Study from MCZ & @harvardoeb.bsky.social reveals surprising totipotency in early worm embryos, going against previous assumptions that because individual cells at this stage have different roles, removing or rearranging them would prevent growth of a complete organism. @currentbiology.bsky.social

Harvard students traveled to the Florida Keys over spring break for the @harvardoeb.bsky.social course Biology and Evolution of Invertebrate Animals, looking for creatures like this sea slug. The MCZ funds spring break trips for many OEB courses, adding a meaningful field component to classwork.

Let’s Botanize! "101 Ways to Connect with Plants” is officially published! OEB alumns Ben Goulet-Scott (PhD ‘22) & Jacob Suissa (PhD ‘23) of @letsbotanize new book is out now! What are you waiting for? Go get yours now! tinyurl.com/3w9xaxjs

OEB is thrilled to announce that Carrie Albertin has officially joined as Assistant Professor of Organismic and Evolutionary Biology and Assistant Curator in Malacology at @mczharvard.bsky.social Please join us in welcoming Professor Albertin!

A new study from @invertebratepal.bsky.social describes a new sea scorpion species that shows these animals were skilled predators much earlier than the fossil record showed! The study is led by Peter Van Roy, Ghent University, & co-authored by OEB PhD candidate Jared Richards. tinyurl.com/bdcwmrws

A new study in iScience led by Karma Nanglu at UC Riverside & Prof. Javier Ortega-Hernandez @invertebratepal.bsky.social reveals that a parasitic worm, called spionids, still plaguing oysters today has been drilling into shells for nearly half a billion years & has barely changed! #fossils #parasi

A new species of a tiny deep-sea limpet reveals big secrets of the deep sea! New study from Professor Gonzalo Giribet's lab describes an exciting find from the 2023 @nautiluslive.org expedition to the remote Johnston Atoll

Congratulations to OEB alum Wendy Valencia Montoya (PhD '25)

A new study by Professor David Combosch (former postdoc) and OEB Professor Gonzalo Giribet reveals the surprising sex determination system in the living fossil, Nautilus #evolution #genetics #cephalopod #chromosome

Postdoc Sarah Losso & Professor Javier Ortega-Hernández new study in BMC Biology analyzed 156 limbs from 28 well-preserved Olenoides serratus fossil specimens and solved the mystery of how these ancient Cambrian trilobites moved their limbs! @invertebratepal.bsky.social

A new study by RJ Knecht (PhD '25) confirms a Cambrian fossil, Palaeocampa anthrax, that was misidentified for 130 years is the oldest and first-known nonmarine lobopodian, an ancient relative of modern arthropods

OEB is pleased to welcome our new Co-Chairs Professors Ben de Bivort and Mansi Srivastava! @debivort.bsky.social

How did mammals go from sprawling to an upright position? Postdoc Robert Brocklehurst & Professor Stephanie Pierce have the answer and it's a surprising winding, dramatic one!

A new study from @harvardoeb.bsky.social found that 21% of the greenhouse gases in groundwater are emitted into the air before the water integrates into streams. Words by @sarahderouin.com eos.org/research-spo...

Join Professor Andrew Davies and conservation scientist Fiona "Boo" Maisels from WCS, on Mongabay Explores Podcast, where the researchers explain the ecological benefits of forest elephants, why they are crucial for forest health, and what could happen we lost them. tinyurl.com/t7tzwk5a

New study, led by postdoc @jopabinia.bsky.social finds true crabs left the marine environment 7-17 times & are 45 mil yrs older than previous estimates, dating to the Middle Triassic alongside some of the earliest dinosaurs! t.co/RzPPZVU34q
