A team of researchers from the College of Arts and Sciences Department of Physics and Astronomy has made a discovery that has changed the "elementary textbook" description of protons.

Professors Keh-Fei Liu and Terrence Draper, along with postdoctoral scholar Jian Liang, are co-authors of a study titled "Proton Mass Decomposition from the QCD Energy Momentum Tensor" that was published this past fall in Physical Review Letters. Since then, the study has gained national attention in the world of physics, as its results have opened doors for more calculations and theoretical understanding.

The team recently explained to UKNow exactly what they learned and what it means for their scientific community.

The University of Kentucky is hosting the third annual Expanding Your Horizons Conference for middle school girls and their parents or guardians from 10 a.m. to 4:30 p.m. EDT Saturday, April 20. This day of hands-on workshops will inform young Kentucky girls and their parents about exciting career opportunities in science, technology, engineering and mathematics.

Women continue to be underrepresented in science, technology, engineering and mathematics fields, and they hold a disproportionately low share of STEM undergraduate degrees, particularly in engineering, according to a study from the U.S. Department of Commerce.

“Many higher education institutions like UK struggle against the problem of poor retention of female undergraduates in a lot of science, engineering and math majors,” said Ellen Crocker, assistant professor in the

The University of Kentucky Chemistry-Physics Building is getting a much-needed transformation.

The central campus staple is currently undergoing a two-phase construction project that will result in a renovation of the third floor, as well as a completely new exterior façade of the building, including a three-story entrance/atrium.

The first phase of the transformation — the third floor renovation — is already underway, and will produce 15 research labs, plus support spaces, equipment spaces and offices. The second phase will bring a new exterior façade, which will include a replacement of the building exterior and roof; construction of a new stair tower, a freight elevator, a new loading dock and entrance additions; and mechanical upgrades in the penthouse.

"When the renovation is complete, this building will be a more pleasant, open

Eighteen University of Kentucky students are making their way to the State Capitol Building in Frankfort, Kentucky, to present their research at the 2019 Posters-at-the-Capitol event. This one-day annual event is held to show Kentucky legislators the importance of undergraduate research and scholarly work in Kentucky. The governor proclaims this day to be Undergraduate Research Day across the Commonwealth.

"Posters-at-the-Capitol is a platform whereby undergraduates from across the Commonwealth’s eight public institutions proudly showcase their undergraduate research projects," said Evie Russell, assistant director at the Office of Undergraduate Research. "Each year, University of Kentucky students look forward to communicating their research achievements to Kentucky Legislators and their peers."

The University of Kentucky Society of Physics Students (SPS) chapter has won an Outstanding Chapter Award and a Chapter Research Award from the SPS National Office. The Chapter Research Award is a competitive financial grant for a yearlong research project.

With the Outstanding Chapter Award, SPS chapters are recognized for high levels of interaction with the campus community, the professional physics community, the public and with SPS national programs. The outstanding chapter designation is given to less than 10 percent of all SPS chapters in the United States and internationally. Although this is the second time the UK chapter has received this award, it has

With continuous funding from the National Science Foundation (NSF) and NASA since 1981, Gary Ferland has developed a special computer code to study how light from distant celestial bodies is produced.

"In astronomy, we (have to be) very clever in figuring out ways to analyze the messages that the stars send us, and the light we receive is difficult to interpret; it's not produced in a simple way," said Ferland, who is a professor in the UK College of Arts and Sciences'

Organizers of Expanding Your Horizons are looking for University of Kentucky students who are interested in being workshop leaders for the 2019 conference. Expanding Your Horizons is a one-day conference on April 20 for middle school girls from across Kentucky. The purpose is to expose them to the STEM fields of science, technology, engineering and mathematics by taking part in hands-on science workshops.

Women make up only 24 percent of the STEM workforce, and women hold a disproportionately low share of STEM undergraduate degrees.

“Many times, girls lack role models in those fields, so they may not realize the variety of career options and opportunities that exist for women,” said Ellen Crocker, a conference organizer and postdoctoral scholar in the UK Department of Forestry and Natural Resources.

Aaron Jezghani is an inventor — although he wouldn’t call himself that. He is pursuing a Ph.D. in the UK College of Arts & Sciences in precision nuclear physics, focusing on neutron decay and is fascinated by the hands-on nature of experimental physics. Jezghani spends his days designing, building, and testing all types of equipment — everything from high-voltage instruments to computer data systems.

A large part of Jezghani’s doctoral experience has been the opportunities he has had to give numerous national and international talks thanks to receiving travel scholarships from the Huffaker Travel Scholarship, established by Milton Huffaker (B.S. '57, honorary doctorate '13), the UK Graduate School, and the American Physical Society.

“I just look back in awe at everything that has transpired after coming to UK for grad school,” he said. “

“People have been searching for an EDM (Electric Dipole Moment) of the neutron since 1950. We are trying harder and harder to find the needle in the haystack. If it were discovered at the anticipated level of sensitivity and accuracy that experiments can obtain now, it would be completely revolutionary. It would be evidence for physics that we can’t currently describe theoretically.”

Brad Plaster, associate chair and professor of physics in the University of Kentucky College of Arts & Sciences, lit up as he described his research.

“Protons and neutrons compose the nucleus of atoms. Neutrons have no electric charge. However, they are composed of quarks, subatomic, fractionally charged particles,” he explained. “What the EDM would postulate is that there might be some slight imbalance of positive

The University of Kentucky College of Arts and Sciences has named the first recipients of its Inclusion Fellows program, an initiative for faculty interested in actively orchestrating and advancing efforts to build a more inclusive campus.

Fellows can develop and implement scholarly, community-building, pedagogical, mentoring and networking events, initiatives or programming. The fellowship period serves as a professional development opportunity for the fellows, as it enables them to enhance their responsibilities and bring forth new ideas and measures that will positively affect students.

“The overall goal of the Inclusion Fellows Program is to draw on and support faculty to create sustainable change to enhance inclusivity within the college,” Cristina Alcalde, associate dean of inclusion and internationalization, said. “Over the course
