Fruit flies fed an organic diet recorded better health outcomes than flies fed a nonorganic diet, according to a new study from Southern Methodist University, Dallas. Researchers in the lab of SMU biologist Johannes Bauer found that fruit flies raised on organic foods performed better on a variety of health tests. The flies on organic diets showed improvements on the most significant measures of health, namely fertility and longevity.
The science magazine Discover has covered the research of SMU vertebrate paleontologist Louis L. Jacobs and the infamous Bone Wars of the late 1800s. In a post on Discover's "80 beats" blog, the magazine reprinted the translation of a poem written by frontier naturalist and fossil hunter Jacob Boll. Jacobs came across the poem at the American Museum of Natural History on a label on the back of Eryops specimen No. AMNH 4183.
Jason Heid, an editor with D Magazine's popular Frontburner blog, covered the research of SMU vertebrate paleontologist Louis L. Jacobs and the infamous Bone Wars of the late 1800s.
In the late 1800s, furious fossil speculation across the American West escalated into a high-profile national feud called the Bone Wars.
Powerful discovery tool is at work screening millions of drugs in the search to reverse chemotherapy drug-resistance in cancer.
With Type 2 human diabetes climbing at alarming rates in the United States, researchers are seeking treatments for the disease, which has been linked to obesity and poor diet. Now biologists at Southern Methodist University, Dallas, report they have developed a new discovery tool that will help researchers better understand this deadly disease.
SMU biologists tap supercomputer in fight against recurring cancer when chemotherapy fails.
In 1996 the introduction of "triple cocktail" drug therapy transformed AIDS from a death sentence into a manageable chronic disease. The drug regimen, also known as HAART for highly active antiretroviral treatment, involved treating patients with three or more classes of antiviral medicines.
But the virus fought back. It mutates easily, and the mutations caused resistance to first one and then another drug making up the cocktail. Unsettling reports of newly infected patients with the drug-resistant virus meant researchers needed to find new ways to fight HIV infection.
In his third-floor laboratory in Dedman Life Sciences Building, biologist Robert Harrod and his team are zeroing in on a new way to inhibit the virus that causes AIDS. They already have shown that their approach, which involves the rare genetic disorder Werner syndrome, works when the disorder's enzyme defect is introduced into cells.
Now they are trying to find practical ways to use this pathway to inhibit the AIDS virus. The beauty of this approach is that the AIDS virus will not be able to mutate in a way that can defeat this treatment, says Harrod, associate professor in the Biological Sciences Department of Dedman College.
