Professor Joel Spencer was a rising star in college soccer and now he is an emerging scientist in the world of biomedical engineering, capturing — for the first time — an image of a hematopoietic stem cell (HSC) within the bone marrow of a living organism.

Everyone has inflammation in their body at some point as it is a vital part of the immune system. It’s what happens when white blood cells flow to a wound, whether that is a bruise or a broken bone. Inflammation helps us heal properly and fight infections, but sometimes something in this process goes wrong and inflammation becomes chronic. This is another issue that can lead to serious diseases such as diabetes, arthritis, cancer, heart disease and many others.

A thin layer of compost applied to grasslands could help fight climate change by capturing carbon from the atmosphere and storing it in the soil, recent research shows.

UC Merced Professor Rebecca Ryals and a team of researchers, ranchers and public agencies will demonstrate this practice for the first time in the East Bay. The project, which began Dec. 3, is funded by a California Department of Food and Agriculture Healthy Soils Demonstration grant.

Proteins are miniscule machines inside the body, about 10,000 times smaller than the thickness of human hair. They control all the processes of life — like how cells communicate to each other, how the immune system combats infection, how muscles contract, and how oxygen is picked up in the lungs and delivered to those very same muscles.

A pair of UC Merced researchers are combining computational chemistry and machine learning principles to solve what seems to be an intractable problem at the heart of quantum mechanics: predicting the movement of electrons, also known as electron dynamics.

Like many young women, Calista Lum absorbed the message that she was not as capable as her male peers when it came to science, technology, engineering and math.

Teachers in her Fairfield high school engineering classes often asked if male classmates had done her work for her.

“I just assumed the boys were so much better at it than me,” she said.

UC Merced Professor Peggy O’Day hopes to improve water quality in the California Delta by studying local wetlands.

O’Day is leading a new three-year study of Merced County wetlands that drain into the San Joaquin River and eventually the Delta.

Professor Jing Xu and her students study extremely tiny motor proteins, but their work could make a huge contribution to the growing body of knowledge about Alzheimer’s and other diseases that progressively destroy brain tissue.

When Denzal Martin started his undergraduate work at UC Merced, he wasn’t thinking about a career in physics, interning with NASA or attending graduate school.

The Los Angeles native was studying computer science and engineering. One day, though, he decided to attend a materials science and engineering lecture by visiting NASA scientist Cheol Park.

“It was a very obscure subject to me, but I was interested to learn more,” Martin (’18) said. “The pictures he showed — it seemed like magic how they were fabricating these materials.”

Even a little forest management significantly increases water runoff in the Central Sierra Nevada and other semi-arid regions, while drier forests need more extensive treatments, according to a new study published recently in the journal Ecohydrology.

“The result is more runoff to downstream water users,” said UC Merced Professor Martha Conklin , who led the study.
