Materials Seminar Series to start Friday

Over the past 20 to 25 years, the world has witnessed a major health crisis as a result of the dramatic increase in the emergence of multiple drug resistant pathogenic microorganisms (MDROs).

This emergence has resulted in a growing ineffectiveness of current antibiotic therapies. In turn, this has also stimulated a renewed interest in the development of new antibiotics that similarly adapt.

As part of the Materials Seminar Series, Dr. Rickey Hicks, dean of the College of Science and Mathematics, will present “Antimicrobial Peptides: Design, Biological Evaluation and Biophysical Characterization or the search for a SMART DRUG,” on Friday Sept. 11 from 4 -5 p.m. in Room W1002 of the Science Hall on the Summerville Campus.

Attendance is open to the public.

For more information on the Materials Seminar Series, please contact Dr. Trinanjan Datta (, Dr. Christopher Klug ( or Dr. Shaobin Miao (

The Materials Seminar Series is sponsored by the Georgia Regents Research Institute, the College of Science and Mathematics and the Department of Chemistry and Physics.

Hive highlights vital role of honey bees

The United States’ honey bee population has been in steep decline over the last decade or more, and a special addition to Georgia Regents University is teaching students how to be part of the solution .

In April, Facilities Management Maintenance Supervisor Tim Dobbs installed an observation bee hive in the Shetfall-Cleckley Greenhouse at GRU’s Summerville Campus in collaboration with Biology Professor Donna Wear with the hope that students learn and see firsthand how integral the honey bee is to the earth’s ecological system.

This spring, Professor Wear’s Evolutionary Biology class was the first group to visit the observation hive.

“Mr. Dobbs presented a brief lecture about honey bees to my students, after which they were able to observe sociobiology in action,” Professor Wear said. “They were all enthusiastic about the learning experience.”

“Honey bees are fascinating social organisms from both an ecological and evolutionary perspective. Pollinators are crucial to our global production of food. In fact, about one-third of the human diet comes from insect-pollinated plants, and the honey bee is responsible for 80 percent of that pollination, according to the U.S. Department of Agriculture,” Professor Wear said.

The insect’s vital role in food production is why their disappearance is so concerning. Just last week, the White House outlined its strategy to strengthen the nation’s struggling honey bee and monarch butterfly populations, calling for expanding the acreage devoted to the flowers crucial to the bees’ and butterflies’ survival.

Scientists have yet to isolate a single cause of the honey bees’ demise, called colony collapse disorder, but a certain type of pesticides introduced in the 1990s has been known to interfere with a bee’s homing ability.

“Honey bees are very important to our livelihood. They’re a beneficial bug,” said Dobbs. “I am really proud Professor Wear wanted to do this.”

Dobbs built the Greenhouse’s observation hive himself with a blueprint purchased online. He then stocked the hive with approximately 10,000 bees and checks it once or twice a week. Observers can easily see the worker bees and drone bees performing their respective duties in the hive and, if you’re lucky, watch the queen lay her eggs.

Dobbs has been a bee enthusiast since he was a young boy, and built his first hive 30 years ago.

“Mr. Dobbs has been a beekeeper for many years, and even he has witnessed bee behavior in the observation hive that he had never before been able to observe. The observation hive provides a wonderful teaching and learning opportunity for students of all ages, who need to be reminded of the ecological processes that feed us,” Professor Wear said.
