UK Chemistry Researchers Develop Catalyst that Mimics the Z-Scheme of Photosynthesis

LEXINGTON, Ky. (June 22, 2017) — A team of chemists from the University of Kentucky and the Institute of Physics Research of Mar del Plata in Argentina has just reported a way to trigger a fundamental step in the mechanism of photosynthesis, providing a process with great potential for developing new technology to reduce carbon dioxide levels.

Led by Marcelo Guzman, an associate professor of chemistry in the UK College of Arts and Sciences, and Ruixin Zhou, a doctoral student working with Guzman, the researchers used a synthetic nanomaterial that combines the highly reducing power of cuprous oxide (Cu2O) with a coating of

J.C. Eaves made expanding the study of mathematics throughout Kentucky one of his life’s missions.

"I remember my father telling me the story of how he visited high schools in 119 of Kentucky’s 120 counties," said Jim Eaves, his son. "He put a great importance on math education in Kentucky high schools."

J.C. Eaves grew up in Muhlenberg County in a large family with 11 siblings. He came to UK and earned his bachelor's and master's degrees in mathematics before joining the U.S. Navy during World War II. After the war, Eaves earned his doctorate at the University of North Carolina and, eventually, his path brought him back to his beloved state of Kentucky.

Jim Eaves grew up at the University of Kentucky. His family moved to Lexington when he was in the second grade, when his father became head of the

Growing up in Greenville, South Carolina, Danielle Galyer did not realize how prominent swimming was in her home state. However, the tough competition didn’t stop her from excelling. She began swimming at the age of 6 and just nine short years later at the age of 15, Galyer competed in her first Olympic trials.

“It was really good for me to go the first time and get the stress level of it all out of the way. It’s a really good experience because it is the elite of the elite,” she said.

With a strong work ethic and sense of commitment instilled by her parents, Galyer decided to attend the University of Kentucky on a swimming scholarship. “It was the one place I

It’s a material world, and an extremely versatile one at that, considering its most basic building blocks — atoms — can be connected together to form different structures that retain the same composition.

Diamond and graphite, for example, are but two of the many polymorphs of carbon, meaning that both have the same chemical composition and differ only in the manner in which their atoms are connected. But what a world of difference that connectivity makes: The former goes into a ring and costs thousands of dollars, while the latter has to sit content within a humble pencil.

The inorganic compound hafnium dioxide commonly used in optical coatings likewise has several polymorphs, including a tetragonal form with highly attractive properties for computer chips and other optical elements. However, because this form is

University of Kentucky Associate Professor of Psychology Will Gervais is the lead author of the study “How many atheists are there?,” which appears in the current issue of the journal Social Psychological and Personality Science. Gervais’ study asserts that there may be many more atheists in the U.S. than society believes.

It's tough to figure out just how religious or nonreligious different populations of people are. Widely cited telephone polls (like Gallup and Pew) suggest U.S. atheist prevalence ranges from 3 percent to 11 percent. But, there's heavy stigma leveled against religious disbelief in the U.S., which might make people reluctant to disclose their lack of belief over the phone to a stranger. Using a subtle, indirect

Middle school students are awed when they get the chance to turn a banana into a percussion instrument at the 2017 Expanding Your Horizons STEM workshop for girls.

Sometime during the transition from middle school to high school, girls often find their early interest in science and math steered in other directions, often toward careers that fit comfortably into a box of more “traditional” women’s roles. A recent daylong workshop at the University of Kentucky sought to stem that tide by introducing 120 Kentucky middle school girls to a challenging STEM career.

A multidisciplinary project, Expanding Your Horizons, focused on countermanding some of the possible reasons that girls’ interest in the sciences flag at a certain age, such as peer pressure or a lack of female role models. During the workshop, the young students met many female undergraduate and

The University of Kentucky’s #IAmAWomanInSTEM project has awarded scholarships to 11 UK students for project proposals that promote STEM education and careers for women.

Females are less likely than their male counterparts to pursue an education in the STEM disciplines, which include science, technology, engineering and math. The #IAmAWomanInSTEM initiative, which launched at UK last year, seeks to change that by recruiting hundreds of female student ambassadors who are encouraging the study of STEM and health care among women at UK, and empowering them to persist in those fields.

“As a public research institution and the state's flagship, UK has an important role in promoting graduation of women in STEM majors,” said Randolph Hollingsworth, assistant provost and advisor of the program

For much of his career, University of Kentucky Professor of Anthropology Christopher Pool has been fascinated by Mexico’s ancient Olmec culture, with its gargantuan heads sculpted in stone and more mundane relics its artisans etched in ceramic.

An expert in Mesoamerica, the evolution of complex societies, political economy and cultural ecology and armed with a voracious curiosity, Pool began his fieldwork at the Olmec site of Tres Zapotes, Mexico, in 1995, some 140 years after a farmworker’s hoe first scraped the top of a buried stone head.

After numerous stone monuments were unearthed at Tres Zapotes, additional evidence of a highly sophisticated ancient culture was discovered. Archaeologists were lured away from Tres Zapotes by the discovery of the remains of several other

Tissue regeneration is complex and involves the dynamic interaction of many cellular and physiological processes. Understanding how these processes interact to regulate regeneration requires working across disciplines. In support of an interdisciplinary approach, the National Institutes of Health (NIH) recently awarded researchers at the University of Kentucky a five-year, $1.65 million grant from its National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) to study how inflammatory cells can regulate tissue regeneration in mammals.

The research team is led by Ashley Seifert, assistant professor of biology in the UK College of Arts and Sciences, and John Gensel, assistant professor of

Macrophages from an African spiny mouse promote tissue regeneration.

A team of University of Kentucky researchers has discovered that macrophages, a type of immune cell that clears debris at injury sites during normal wound healing and helps produce scar tissue, are required for complex tissue regeneration in mammals. Their findings, published today in eLife, shed light on how immune cells might be harnessed to someday help stimulate tissue regeneration in humans.

“With few examples to study, we know very little about how regeneration works in mammals; most of what we know about organ regeneration comes from studying invertebrates or from research in amphibians and fish,” said Ashley Seifert, senior author of the study and assistant professor of
