DNA Sequencing Spots Genetic Key to Lupus

August 19, 2014 12:30 pm | News | Comments

Medical researchers have used DNA sequencing to identify a gene variant responsible for causing lupus in a young patient. The development shows that, for the first time, it is feasible for researchers to identify the individual causes of lupus in patients by using DNA sequencing.

Engineering New Bone Growth

August 19, 2014 12:07 pm | News | Comments

Chemical engineers have devised a new implantable tissue scaffold coated with bone growth factors that are released slowly over a few weeks. When applied to bone injuries or defects, the scaffold induces the body to rapidly form new bone that looks and behaves just like the original tissue.

Reactivated Gene Sets Immune System Back 500M Years

August 19, 2014 11:37 am | News | Comments

A single factor can reset the immune system of mice to a state likely similar to what it was 500 million years ago. Scientists reactivated expression of an ancient gene in mice, which is not normally expressed in the mammalian immune system, and found that the animals developed a fish-like thymus.
