Writing Portfolio

rmolar13 (at) aggienetwork.com

I have covered a lot of ground writing about science, health, and engineering. I love the challenge of exploring research that is in the weeds, and writing about it in ways that other people can learn and love as well. As a science writer at research centers including the Carnegie Institution for Science, the National Oceanic and Atmospheric Administration, and NASA, I also have regularly contributed to reports and translations, multimedia, and other types of communications.

These new sensors can detect coronavirus particles on your breath, instantly
Instead of sticking swabs up our noses, what if we could instantly detect viral particles we breathe out? That is precisely the kind of technology that Nian Sun, a professor of electrical and computer engineering, is working on.

This nanomaterial could be our best tool to make renewable energy cheaper
Using a combination of unique nanocrystals extracted from wood, Hongli (Julie) Zhu, an assistant professor of mechanical and industrial engineering at Northeastern, has created a biodegradable material that makes better and cheaper batteries—the kind we need to power entire communities.

Our drinking water was always full of microbes. Are the wrong ones thriving in the pandemic?
It’s been months, and life has changed dramatically across the planet. Zooming in where only a microscope can see, Northeastern researchers are trying to determine how the lifestyle changes caused by COVID-19 might be helping harmful bacteria grow in our water.

We know exercise is good for your skin. This protein mimics those effects in mice.
Skin cells lose their ability to heal themselves with age. Northeastern biologist Justin Crane is testing how a new treatment to heal wounds in older mice can help researchers understand the cellular mechanisms of aging and healing in the skin cells in elderly people.

This model can help hospitals prepare for a surge of COVID-19 cases
Engineering professor James Benneyan helped create a tool to calculate when hospitals might run out of essential resources, such as staff and ventilators, as COVID-19 cases peak.

A US Army veteran who tinkered with machines in Afghanistan dives into computer science
Theresa Todd, a U.S. Army veteran who led logistical operations in Afghanistan in 2014, tinkered with machines and electronics retrieved as U.S forces withdrew. Her fascination with computers brought her to Northeastern, where she is pursuing a master’s degree in computer science in the Align program at the Khoury College of Computer Sciences.

Trend Stories

The person walking past you isn’t wearing a mask. What should you say?
It’s best to avoid hostility and communicate with empathy when it comes to helping people understand why covering their faces can slow the spread of the virus, say Northeastern researchers.

Here’s why washing your hands with soap for 20 seconds protects you from COVID-19
In soap lather, a combination of molecules assemble into bubble-like structures that trap viral matter and other biomaterials—grease, oil, dirt—and rinse them down the drain, says Thomas Gilbert, associate professor of chemistry and chemical biology at Northeastern.

A COVID-19 vaccine won’t mean a swift end for wearing masks or physical distancing
It’s a long process to get a vaccine out to 7.5 billion people, and an even longer one to answer important questions about its efficacy.

Looking at planetary system evolution with Meredith MacGregor
Gas, dust, and small objects. In the beginning, it’s a whole lot of nothing. After these materials collide and combine to eventually make planets, the material that’s left behind forms debris rings around the mature planetary systems. Astronomers call these rings circumstellar disks

‘It’s like being an archaeologist, but for the Solar System’
Scientists consider stony meteorites known as chondrites to be the archives of the Solar System. These space rocks are fragments of primitive asteroids. Even though most chondrites undergo some rough travels before landing on Earth, they are still a major source of information about the conditions of the material surrounding our star when it formed billions of years ago.
