Leeuwenhoek - Father of Microbiology

If you love science, technology, and engineering, chances are you are like me and an "early adopter." An early adopter is defined as, "a person who uses a new product or technology before it becomes widely known or used." Early adopters are often innovators as well. They recognize the value of a new invention or process, try it and then improve it, apply it in a more effective way, or try it in a completely different application.

This was especially the case several hundred years ago when early scientists and engineers had to conceive of and then construct their equipment before using it to seek answers to puzzling questions.

Early Dutch scientist, Antonie van Leeuwenhoek (1632 – 1723) was highlighted this week with a Google doodle for his discovery in 1676 of "little animals" (microorganisms) in rainwater. He saw these through his improved (i.e., he ground and polished his own single lens) version of Robert Hooke's microscope. With this DIY improvement, van Leeuwenhoek went on to study muscle fibers, bacteria, spermatozoa and blood flow in capillaries.

As a scientist trained in microbiology, van Leeuwenhoek is my hero. His improved lens could magnify objects by a factor of about 200 – 300, while Hooke’s compound microscope magnified only by a factor of about 40 – 50. 

Just another example of old school ingenuity and innovation in action. Go science!

Celebrate National Fossil Day

It's finally here! National Fossil Day! Hurray! A special day for dinosaurs (every child's and many an adult's secret wish come true)! It's the perfect time to celebrate your favorite fossil and chat with similarly minded folks about the cool things your favorite dinosaur can do (or did). 

Mine is the Triceratops, with three impressive horns and bony frill around the head. I've always imagined it as one of the solid, hard working dinosaurs. Kind of the bull dog of the plant-eating dinosaur set. 

Today on National Fossil Day a major Tyrranosaurus rex question has been answered by researcher, Mary Schweitzer, Ph.D., who discovered that "Bob" the T. rex was really a pregnant female from dinosaur medullary bone cells found in recovered bone tissue. Medullary bone, also found in modern birds who lay eggs, is a temporary bone tissue that stores calcium for eggshell formation. Without it, the needed calcium would be pulled from the mother's bones (never a good thing, but particularly tricky in light, delicate bird bones.)  Anyway, this is the first time a female gender designation has been found for T. rex

As always, it's exciting to discover big science news after much time (68 million years) has passed. Go science!

Science and Technology Meet Design to Monitor High RIsk Pregnancies

I'm always interested in new and ingenious ways to improve health for everyone, but especially pregnant moms and children. So, I was particularly excited to hear about research on wearable sensors that give physicians a heads up on early labor and baby movement.

Supported by the National Science Foundation, electrical/computer engineer Kapil Dandekar, industrial/fashion designer Genevieve Dion, and OB-GYN physician, Owen Montgomery have added radio frequency identification (RFID) technology into their “belly bands” for women with high-risk pregnancies. The wearable sensor constantly tracks movements and signals the physician via the Internet if a patient begins early contractions. A petite sensor band is in the works for babies at risk for sleep apnea.

Combining engineering, medicine and fashion design, this trifecta of human-centered technology offers simple-to-use, yet critical tools for better healthcare. Go science!

Curiosity and The First Day of School

Most of the time, people are resistant to change. We like the comfortable, "I have this down" feeling that comes with time and repeated experiences. 

I was thinking about this aversion to change while sitting in the slowed traffic that comes with the start back to school. I drive past 2 schools on my way to work, so I get to see eager students in their new clothes saying good-bye to caring, committed, and/or harried parents trying to get to work on time.

Well, okay maybe the older students are not so eager. Maybe not some at the middle school either. But mostly, the young ones are excited to see friends who they may not have seen over the summer months. 

Why aren't they all equally excited?

I believe young children are still mostly information sponges. They ask why a million times a day (or so it seems). Change is their watchword, their motto, their way of life. It isn't until much later when they have had a few failures or someone older has explained an idea is impossible that curiosity dims and change becomes something to be avoided. 

So the next time you talk with friends, parents, and colleagues, think about that. Curiosity is important and one we need to nurture and celebrate not just on the first day of school, but every day. Curiosity and asking why are the foundation of the scientific method. Go Science!
