When scientists announced in 2003 that they had finished the Human Genome Project, they were quick to clarify that sequencing of the full human genome not yet complete. As much as six percent of the genome was beyond the reach of available technology, leaving regions on the 23 pairs of human chr... Read More
Type 1 diabetes (T1D), formerly known as juvenile diabetes, is a multifactorial disease of complex etiology characterized by the autoimmune destruction of pancreatic beta cells. In addition to genetic susceptibility, it is generally accepted that environmental factors play important roles in tri... Read More
There is no question that HIV is an ugly virus in terms of human health. Each year, it infects some 2.7 million additional people and leads to some 2 million deaths from AIDS. But a new album manages to locate some sonic beauty deep in its genome. Sounds of HIV (Azica Records) by composer Alexan... Read More
Older adults who develop sepsis — a serious, widespread bacterial infection -- are at risk of declining both mentally and physically in subsequent years, a new study has found.
