Researchers discover potential treatment for Friedreich's ataxia

Using clever chemistry, a Scripps Research team has pinpointed the enzyme target of a drug group that stops the progression of the devastating disease Friedreich's ataxia in mice and may do the same for humans. The findings, developed in collaboration with scientists from Repligen Corporation, help advance this treatment approach one step closer toward human clinical trials, which will be a welcome event for disease sufferers who currently have few treatment options.

Researchers figure out how nuclear pores duplicate before cells divide

Researchers have long wondered how nuclear pores - the all-important channels that control the flow of information in and out of a cell's nucleus - double in number to prepare for the split to come when a cell divides. Now, for the first time, scientists at the Salk Institute for Biological Studies watched as new funnel-like pore structures formed from scratch, and inserted themselves into the nuclear membrane.
