Sometimes all you can do is make the world 0.0000000000001% less awful by being a good person and it feels very meaningless but it’s also the only thing that really matters

Evolution loves a crab - they've independently evolved so many times there's even a word for it (carcinisation) 🦀 #SciArt #crab #carcinisation #marinebiology

Illustrating water quality challenges - this is some of my recent work showing how fire, roads & tracks, and eroding gullies can impact water quality (& how a gully can be repaired!) These were created for my work with TropWATER & their collab with the Cape York Water Quality Partnership #SciArt

Introducing Deep Time Detectives! 🔎 Deep Time Detectives is an educational resource developed by CABAH on Australia's deep history, featuring a series of animated videos. I drew a collection of original illustrations and animated elements for these videos #SciComm emmarehn.com/portfolio/de...

I have some exciting news to share! A bunch of friends (and amazing artists) and I are hosting an art challenge this August 🌻 We put together a fun and chill prompt list and hope you’ll join us on this adventure hehe More below 🐥

I was recently commissioned to create two illustrations for The Australian Geologist, the quarterly magazine of the Geological Society of Australia One highlights featured research, the other is just for fun! Read the TAG June issue here: issuu.com/gsaustralia/... #geology #sciart #scicomm

Happy National Archaeology Week! This year's craft in celebration of Archaeology Week is little clay pendants - the scale bar is 4cm #2025NAW #archaeology #craft

Applications close this Sunday for this year's ABC TOP 5 media residency! If you're an Australian ECR with an interest in boosting your comms skills, I recommend applying - I'm happy to answer questions as a 2022 awardee Here's the link to the Science stream (Humanities & Arts also open) #scicomm

Everyone please go have fun scribbling, painting, drawing, and otherwise finding joy in making art 🎨 #WorldArtDay #Artsky

Happy Pi Day! 🥧 This is my first time making pies, so I went for mini ones to share at work

Happy Lucy day, everyone 🐾

Today is the International Day of Women and Girls in Science! 🧪 To celebrate at my work, I asked some of the brilliant researchers I work with about their experiences in science - and their passion for it really shines through #InternationalDayofWomenandGirlsinScience

Like Micha, I was lucky enough to receive an AINSE PGRA during my PhD, and I second Micha's recommendation to apply! A great opportunity for Aus/NZ PhD students who could benefit from using ANSTO facilities for their research, such as radiocarbon and lead-210 dating labs #AcademicSky

This week, I'm celebrating reaching 1k followers! 🎉 If you follow me: comment with a few words about your research/area of expertise and some things you enjoy - and I'll sketch a little cartoon for you

My favourite group in the WHOLE WIDE WORLD are kicking off their Bluesky account properly, with trials and tribulations of experimenting with tech for successful online meetings, events and collabs. Now more than ever, we need to be together, even when we’re apart 🌏.

I made time these holidays to sketch while out and about - here's a selection of those sketches and their models #sketchbook

I'm proposing a #SciArt Challenge for 2025! Every month, make art of one of the animals that lives in your area. Post your work with the hashtag #NearbyNature2025 along with something you find interesting about them. Bonus points for organisms that most of your neighbors won't know live close by!

My science illustration commissions are open! If you want to visualise your research this year through custom illustrations, logos, or infographics, please get in touch Visit emmarehn.com for my portfolio and contact info #SciArt #SciComm #ScienceIllustration

Throwback to my favourite Christmas artwork to wrap up #ArtAdventCalendar for this year Happy holidays, everyone!

My festive activities today included making Christmas crackers/bon bons, baking gluten free shortbread, and watching the live stream of this great VR performance of A Christmas Carol 🎄 One day I'll invest in a headset and get to join in VR!

Layers of the atmosphere ☁️ I made this for my own reference, and for anyone else who is interested - some new #SciArt for #ArtAdventCalendar! #SciComm #EarthScience

#ArtAdventCalendar - my latest craft project was designing matching Christmas gifts for my trivia team #crochet #crafting

Digging out an old comic for today's #ArtAdventCalendar 'Solitaire' (2010)

During the recent evenings spent waiting for coral to spawn, I sketched some coral 🪸 (& didn't get time to finish it!) Sharing for #ArtAdventCalendar - I won't be posting daily, but I'll be joining in whenever I can 🎄

What time is it?? 🎄

If you see this, post fungi 🍄

One for the Quaternary folks! Here are some of the researchers working in the many fields that form #Quaternary science across Australasia. Please let me know who I've missed, or if I've missed you! go.bsky.app/Lt9yvgX

Looking for recommendations! Can any art / #sciart folks recommend a good standalone graphics tablet? I've only ever used Wacom tablets that tether to my laptop, and I'm interested in something more portable ✍️

Update: I went back tonight for a final evening of staring at corals, and three decided to spawn Number 7 - shown here - put on a lovely show, spawning slowly for about 45 minutes 🪸 #coralspawning

This week was the annual #coral spawning on the Great Barrier Reef - and in the lab at my work 🪸 I got to be there for the spawning of one coral - number 8, my new favourite - after several nights of (im)patiently waiting My role was photographer, so pipetting spawn bundles was an added bonus!

Mind the gap. #Archaeologists are excited about #dinosaurs as much as everybody else - but we don't dig them. Not literally. That's where our colleagues in #palaeontology come in - there's a good sixty-four million years of evolutionary history between the Flintstones and their pets. 🏺🦕

I'm becoming more self-aware about this, yet it changes nothing New #comic!

All of the family has been mulching the garden together this week, including my dog Lucy Her role is Chief Supervisor, of course - and elegant Queen of the Mulch Pile

I probably don't need to make myself printed business cards, really But on those very rare occasions when I could give someone my card, as happened today, I'm always tempted
