When Professor Asmeret Asefaw Berhe arrived at UC Merced in 2009, she and her husband, Professor Teamrat Ghezzehei, were leaving major research institutions to join a brand-new campus in California’s Central Valley. It was a leap of faith — one made easier by the Sierra Nevada Research Institute.

As nations cut emissions that once fueled urban smog, scientists are discovering unexpected chemistry taking place in the atmosphere.

UC Merced Professor Xuan Zhang is leading a project to uncover how these chemical shifts could affect the air we breathe and the climate. The project is supported by a National Science Foundation CAREER Award.

Zhang is the 43rd researcher from UC Merced to earn a CAREER award from the NSF.

As the Hellman Fellowships celebrate their 30th year, three more researchers, one from each of UC Merced’s schools, have joined the prestigious ranks of recipients.

Electrical engineering Professor Qian Wang, sociology Professor Meredith Van Natta and Earth systems Professor Adeyemi Adebiyi will receive funding through their fellowships for projects they have proposed.

Rolando Ortega is closing in on his dream of earning a Ph.D. This fall, the Cal-Bridge scholar from Los Angeles County joins UC Merced to start his doctoral journey. With experience spanning national labs, NASA outreach and cutting-edge research, Ortega is ready to design devices that push the boundaries of science and technology.

Starting a university from scratch isn’t for the faint of heart — or the slow of foot. Lucky for UC Merced, Anne Myers Kelley and David Kelley are neither.

Anne, a former Olympic marathon trials qualifier, and David, a competitive cyclist, were no strangers to long, grueling efforts when they packed up their lab gear and headed west from Kansas State University in 2003.

In addition to being used recreationally, marijuana and cannabidiol, or CBD, one of the cannabinoids produced by the marijuana plant, are thought to have medical benefits such as helping with chemotherapy-induced nausea, treating epilepsy, relieving pain and helping with a variety of mental health issues.

Department of Molecular and Cell Biology Professor Chris Amemiya, former interim director of the Health Sciences Research Institute, has been honored by the Pan American Society for Evolutionary Developmental Biology (PASEDB) with the Service Award.

More than 100 million land mines remain buried around the world, posing a threat in approximately 70 countries and territories, and killing or injuring about 5,000 people, most of them civilians, every year. 

As the world’s geopolitical landscape shifts, nine scientists studying different aspects of warfare ecology from seven countries — Poland, Ukraine, Norway, Spain, the United States, Finland and Croatia — are warning against the growing deployment of land mines as countries bordering Russia withdraw from global conventions restricting their use.

Shark Week starts Sunday and Professor Sora Kim will be featured again this year in a special airing at 9 p.m. Monday, titled “Jaws vs. Mega Croc,” and the filming allowed her to swim with a Nile crocodile.

“I flew to Florida and learned about crocodiles – their evolution, strength, physiology and behavior. More interactions are being recorded between sharks and crocodiles these days, so I also needed to learn about these situations,” she said.
