STEM Science Fair Projects Help Students Prepare for Real-Life Careers

Science fair projects are a great way for students to test out their interest and aptitude for a career in STEM (science-technology-engineering-math). But they shouldn’t choose just any old topic. Try to focus on projects with real-world applications that will give them some experience in a good-paying job field, like engineering. With planning and hard work, the right science fair project might bump up a student’s chances for a scholarship or Continue reading

GMU professor’s “Nanoparticle Net” may detect early cancer, Lyme disease

Women in Science and EngineeringAlessandra Luchini, a Ph.D. and assistant professor at George Mason University, has helped to invent a “nanoparticle trap” which allows scientists to detect unhealthy cells much sooner than before. When found early, cancer and other diseases are easier to treat, giving patients a better chance for survival.

Recently, Luchini gave a lecture on “Nanotechnology in Biomedicine” as part of Mason’s Vision Series at the Hylton Performing Arts Center in Manassas, Virginia. Continue reading

Women in Science and Engineering: Environmental Problem Solver Leslie Guth

Women in Science and EngineeringIn this fourth and final post celebrating Women’s History Month, I will highlight another AT&T scientist who I was privileged to cover early in my career as a writer. Though I worked in Media Relations at AT&T Bell Laboratories from 1987 to 1990, I did not meet Leslie Guth until after I had left the Labs to begin freelancing.

Then, in 1991, I interviewed her for an article in Woman Engineer magazine. Guth had arrived at the Bell Labs Engineering Research Center in 1984, fresh from earning her Ph.D. in Materials Science and Engineering Continue reading

Women in Science and Engineering: Fiber Optics Expert Suzanne R. Nagel

Women in Science and EngineeringIn honor of Women’s History Month, this is the third in a series of posts on some of the accomplished women scientists and engineers I have had the privilege of interacting with throughout my career. Back in 1986, I interviewed almost a dozen women working in fields related to lasers for an article in Lasers & Applications magazine.

Today I focus on another of these women, Suzanne R. Nagel, an engineer at AT&T Bell Laboratories in the area of fiber optics.

Suzanne R. Nagel, Ph.D.

Suzanne R. Nagel, Ph.D.

Without her, you wouldn’t be reading this online. No, she didn’t invent the internet. But she helped make it possible to create the first transoceanic fiber optic cable, leading to today’s high-speed data transmission that makes our world-wide internet service possible. Continue reading

Additive manufacturing: 3D printers and much more


In today’s manufacturing world, 3D printers (3DP) bring a lot of buzz to product announcements, trade shows and Kickstarter challenges. Ditto for the tech geek space.

But the breathless push for a 3D printer in every home, like the 70s quest for a computer on every desk, may detract from the real industrial revolution in additive manufacturing (AM). Continue reading
