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

Georgia Tech/Emory Center for Regenerative Engineering & Medicine

Regenerative Engineering & Medicine highlights

Last week on Friday, Lab Land attended the annual Regenerative Engineering & Medicine center get-together to hear about progress in this exciting area.

During his talk, Tony Kim of Georgia Tech mentioned a topic that Rose Eveleth recently explored in The Atlantic: why aren’t doctors using amazing “nanorobots” yet? Or as Kim put it, citing a recent review, “So many papers and so few drugs.”

[A summary: scaling up is difficult, testing pharmacokinetics, toxicity and efficacy is difficult, and so is satisfying the FDA.]

The talks Friday emerged from REM seed grants; many paired an Emory medical researcher with a Georgia Tech biomedical engineer. All of these projects take on challenges in delivering regenerative therapies: getting cells or engineered particles to the right place in the body.

For example, cardiologist W. Robert Taylor discussed the hurdles his team had encountered in scaling up his cells-in-capsules therapies for cardiovascular diseases to pigs, in collaboration with Luke Brewster. The pre-pig phase of this research is discussed in more detail here and here. Read more
