New HMI Science Nuggets are available at http://hmi.stanford.edu/hminuggets, featuring the following topic
Hemispheric helicity preference in groups of active regions with different properties suggests different origins of magnetic twist.
We invite those who use HMI data for their research, or whose research
is closely related to HMI science objectives, to contribute to the HMI
science nuggets. -- SDO/HMI team
