Bioplastics for the lab are finally here!
But there’s a big problem — few people actually know what bioplastics are.
Here’s what you need to know 🧵👇

If you work in science, you need to adopt sustainable practices now - otherwise, you may soon lose funding.
2 of the world’s largest funders already require labs to report:
🔹 Cutting plastic waste
🔹 Reducing energy use
🔹 Traveling less
If not, applications won’t be considered.

Quick tip to spot greenwashing:
- Some push “infinite recycling loops” that don’t exist
- Others fudge carbon accounting
- Or pretend an analysis = certification
👉 Just ask the company for details.
If claims are exaggerated, you’ll likely hear… nothing.
❌ Silence = red flag

Something we should tell every graduate:
Uni won’t teach you to follow your❤️but it will shape your career.
After graduation, the structure disappears.
You need to forge your own path.
What I heard scientists advise: Listen to your heart it will lead you properly

There’s a new publishing model you should know about.
🔹 Subscribe to Open (S2O)
If enough libraries keep subscribing, the journal flips to 100% open access for that year.
If not, it falls back to subscriptions + APCs.

Research labs generate tons of plastic waste every year.
But what if making science greener didn’t require extra effort from scientists? 🧪
Here’s how one of the world’s leading institutes tackled it—Leibniz-HKI 👇

It finally happened.
AI can now write systematic reviews better than humans.
And it only takes 2 days...
A group of researchers (Cao et al.) built a workflow using freely available AI tools to:
🔹 Screen papers
🔹 Extract data
🔹 Run meta-analyses
All without any hefty coding.
