Dear MDPI,
Please don’t cancel my “invitation to review” after I accepted to review your manuscript. The world won’t stop turning if a review is a day or 2 late. Also, please also stop asking for reviews within 10 days. No one needs or is expecting that.

Terrible headline - they found interesting sulfur isotope ratios, not an “exotic new element”.

Curiosity still has a lot to offer after nearly 13 years on Mars, yet the mission is at risk if NASA goes forward with proposed massive cuts.
Organic molecules of unprecedented size discovered on Mars
These long carbon chains, containing up to 12 consecutive carbon atoms, could exhibit features similar to the fatty acids produced on Earth by biological activity. #Mars 🧪🔭

I would suggest we start with the repatriation of 🇨🇦 scientists who left due to lack of jobs/opportunities/funding.
Canada is home to world-class scientists and researchers. We have a unique opportunity to recruit top US talent amid their recent major research cuts.
What's our plan?
