Carolyn Wilke earned her Ph.D. in environmental engineering at Northwestern University, where her research drew on the fields of environmental chemistry, materials science and toxicology. She got her start in science writing by blogging for HELIX, Northwestern’s science magazine and wrote as a AAAS Mass Media Fellow at The Sacramento Bee. Now a freelance science writer. Carolyn worked as a staff writer at Science News Explores and interned at Science News and The Scientist. When not delving into a new scientific discovery, you might find Carolyn behind her sewing machine or trying to amuse her cat.

All Stories by Carolyn Wilke
- Chemistry
Scientists Say: Periodic table
The periodic table is a chart showing all the known chemical elements. An element’s location in the table reveals a lot about its chemistry.
- Health & Medicine
Could Wednesday Addams really jolt a frog back to life?
A spark that recalls some science history brings a dead frog to life in The Addams Family. Scientists are now using electricity to build the body.
- Health & Medicine
Scientists Say: Lymph
Lymph is a colorless fluid that bathes the body’s tissues and mops up bacteria, viruses and wastes.
- Tech
This robot catches jellyfish with a gentle ‘hug’
A soft robotic hand gently catches jellyfish by trapping the creatures within its silicone fingers.
- Materials Science
Scientists Say: Crystal
The atoms or molecules in crystals take on a particular, repeatable pattern.
- Archaeology
Scientists Say: Mummy
Mummies are dead bodies that don’t rot. They can form under natural conditions or because of chemicals that stop decay.
- Space
Could humans build a tall tower or giant rope to space?
The movie Ad Astra shows a space antenna, a spindly structure reaching up into the stars. We look at what it would take to build something that big.
- Life
Scientists Say: Zooxanthellae
Algae called zooxanthellae live in the tissue of coral and provide the coral with food and its color.
- Space
Scientists Say: Galaxy
A galaxy is a group of millions to billions of stars, plus a lot of dust and gas.
- Climate
Night-glowing clouds crept south this summer
Clouds typical of polar skies have been showing up over the lower United States. Scientists want to know why.
- Animals
Ancient crocodiles may have preferred chomping plants, not meat
Fossil teeth of ancient crocodilians suggest that some ate plants and that such green diets evolved in crocs at least three times more than 60 million years ago.
- Animals
Some mama whales may whisper to keep calves safe from orcas
Even enormous whales can fear the threat that orcas pose to their babies. It now seems that some have taken to whispering to help their young stay off the killer whales’ radar.
