University of Arkansas researchers have simulated the effect of a series of retention ponds in the West Fork of the White River Watershed and found that construction of 22 one-acre ponds, with an average flood-pool depth of 8.2 feet, in sub-basin areas can decrease peak-flow runoff by about 15 percent. Such a retention pond system would have the potential to significantly decrease water loss from runoff in watersheds of at least 75,000 acres.

CEO retirements – the most common reason for executive succession and yet a relatively overlooked area of research – are assumed to be an inconsequential part of normal business and therefore not disruptive to an organization. A new study by management researchers at the University of Arkansas shows this conventional assumption to be inaccurate. According to market data, shareholders perceive CEO retirements to be a significant disruption to the viability of an organization.

From terrorist propaganda distributed by organizations such as ISIS, to political activism, diverse voices now use social media as their major public platform. Organizations deploy bots — virtual, automated posters — as well as enormous paid “armies” of human posters or trolls, and hacking schemes to overwhelmingly infiltrate the public platform with their message. A University of Arkansas at Little Rock professor of information science has been awarded a grant to continue his research that will provide an in-depth understanding of the major propagators of viral, insidious content and the methods that make them successful.

Identifying a patient’s genetic mutation led University of Arkansas for Medical Sciences (UAMS) physician-researcher Ling Gao, M.D., Ph.D., to an existing drug that eliminated the patient’s stage IV Merkel-cell carcinoma. Gao’s findings, made in collaboration with two other UAMS researchers, were published today in The New England Journal of Medicine. Metastatic Merkel-cell carcinoma is often fatal and there is no effective treatment. Gao’s 86-year-old female patient was diagnosed in 2013 with stage IIIB Merkel-cell carcinoma of the right temple. She had surgery and received radiation therapy in May 2013 and additional surgery in July 2014. In November 2014, doctors confirmed that the cancer had metastasized.

A team of researchers has validated data and found a new model for paleontologists to use to track the diet of our ancient ancestors and animals by analyzing the wear on their teeth. Dental wear is among the top techniques scientists use to reconstruct and analyze dietary patterns of human ancestors and animals. Researchers recently questioned the validity of tooth-wear analysis, however, stating that environmental elements such as grit on food was likely responsible for wear. This challenge has led paleontologists to question decades of results. This study validates the use of tooth wear for understanding diet of fossil animals.
