Bird flu shuffle probes viral compatibility

The good news is that packaging signals on the H5 and H7 viral RNA genomes are often incompatible with the H3N2 viruses. But mix and match still occurred at a low level, particularly with Read more

A life consumed by sleep

Nothing he tried had worked. For Sigurjon Jakobsson, the trip to Atlanta with his family was a last-ditch effort to wake up. He had struggled with sleeping excessively for several years before coming from Iceland to see a visionary neurologist, who might have answers. In high school, Sigurjon was a decathlete competing as part of Iceland’s national sports team. But at the age of 16, an increasing need for sleep began to encroach upon his life. Read more

Laughter may be best medicine for brain surgery

Decoding lupus using DNA clues

People with systemic lupus erythematosus can experience a variety of symptoms, such as fatigue, joint pain, skin rashes and kidney problems. Often the symptoms come and go in episodes called flares. In lupus, the immune system goes haywire and produces antibodies that are directed against the body itself.

A team of Emory scientists has been investigating some fundamental questions about lupus: where do the cells that produce the self-reactive antibodies come from? Are they all the same?

In the accompanying video, Kelli Williams, who helps study the disease and has lupus herself, describes what a flare feels like. In addition, Emory researchers Iñaki Sanz, MD and Chris Tipton, PhD explain their findings, which were published this summer in Nature Immunology.

Judging by the number and breadth of abstracts on lupus at the Department of Medicine Research Day (where Tipton won 1st place for basic science poster), more intriguing findings are in the pipeline. Goofy Star Wars metaphors and more explanations of the science here.
