A University of Arkansas researcher is part of a team of astronomers who have identified an outburst of X-ray emission from a galaxy approximately 6.5 billion light years away, which is consistent with the merger of two neutron stars to form a magnetar -- a large neutron star with an extremely powerful magnetic field. Based on this observation, the researchers were able to calculate that mergers like this happen roughly 20 times per year in each region of a billion light years cubed.
What does it take for plants and animals to evolve in response to climate change? Researchers have found a “tipping point” at which species, under pressure from dwindling food supplies, evolve to take advantage of new resources.
Mechanical engineering researchers have developed a method that could extend the life of an artificial hip by adding an array of microscopic indentations that increase the thickness of a lubricating film on its surface.
Study will identify how groups of deer are related to one another throughout the state and determine which populations are less susceptible to the disease
A research team including U of A faculty has developed a method of detecting single photons using quantum dots. Single photon detection using quantum dots is an important element of new technology that could lead to faster and more secure data transfer.

Kyle Quinn, assistant professor of biomedical engineering at the University of Arkansas, has published a review highlighting recent advances in autofluorescence imaging and discussing its role in evaluating cell metabolism.
Obesity is concentrated in “high-risk communities, where residents have limited access to healthy foods, limited open/green space, a lack of quality and accessible health care,” the report states, a so-called “ecology of disadvantage.”
When it comes to staying hydrated, “just drink when you’re thirsty” has been a rule of thumb for years. Yet a recent study by University of Arkansas researchers may prove that thirst alone is not a reliable indicator of proper hydration levels.
Transportation researchers at the University of Arkansas and their collaborators at five other research institutions will continue to lead the nation in maritime and multimodal transportation research with an additional $1.4 million grant from the U.S. Department of Transportation. The grant will be used on a wide range of ongoing research.
Gary Prinz, assistant professor of civil engineering at the University of Arkansas, has received a $500,000 Faculty Early Career Development award from the National Science Foundation to develop mathematical models to predict micro-level material fractures in steel alloys made by additive manufacturing, popularly referred to as 3-D printing. The research could lead to building components that are better able to resist the damaging effects of earthquakes.
Tim Muldoon, assistant professor of biomedical engineering, has received a $500,000 Faculty Early Career Development Program award from the National Science Foundation to continue his work on an endoscopic probe that can be used in colonoscopies. The device is intended to provide superior images of living tissue within the gastrointestinal tract and other structures.
A study of domestic violence victims finds that Hispanic women seek legal help more often than non-Hispanic white women, and the two groups have different reasons for remaining in abusive relationships.
Engineering researchers at the University of Arkansas have moved closer to developing an alternative method of detecting and possibly treating breast cancer. The researchers work with pulsed, terahertz imaging, a type of electromagnetic radiation technology previously used to find land mines. They adapted the technology to detect tumors and provide highly specific images.
A research collaboration between the University of Arkansas and Fayetteville High School suggests that students benefited more when using the same type of modeling software used by scientists than through other instructional techniques.
A new study shows that individuals who possess high primary psychopathic characteristics appear to have distinct advantages over those who don’t, when working for an abusive supervisor.
Researchers from the University of Arkansas' Terrorism Research Center are using Risk Terrain Modeling to investigate links between terrorism events and their precursors.
Researchers at the University of Arkansas and the Ministry of Education of China studied expert and non-expert video game players and observed that both groups showed an increase in visual selective attention after only one hour of video game play.
A multi-institutional team of researchers, led by University of Arkansas engineering professor Shui-Qing “Fisher” Yu and a leading Arkansas semiconductor equipment manufacturer, have made significant improvements to a new kind of laser, a semiconducting device that is injected with light, similar to an injection of electrical current. This “optically pumped” laser, which is made of germanium tin grown on silicon substrates, could lead to faster micro-processing speed at much lower cost.
U of A engineering and agriculture faculty are working with the National Cattleman’s Beef Association to identify practices that will increase efficiency and sustainability in the beef industry.
A new study by geologists at the University of Arkansas provides a new framework for assessing why and where river deltas branch and will help government agencies plan for sustainable development in environmentally sensitive areas.
A University of Arkansas finance professor and his colleague at Purdue University found that some private equity firms, despite their reputation as job destroyers, increased employment following a buyout. Most of these firms had political connections, and the jobs they created or retained after buyouts were concentrated during election years in swing states or states that the researchers identified as having “high corruption.”
