A Johns Hopkins University team has built a yeast chromosome from scratch, they report today in the journal Nature. Sarah Richardson used what she learned as a Computational Science Graduate Fellow to help design and monitor the chromosome’s construction.
For one summer, Sarah Richardson postponed her work computerizing yeast genome research and probed bacteria instead. As part of her

While others predicted when oil from the Deepwater Horizon spill in the Gulf of Mexico might reach beaches, ocean modelers at Los Alamos National Laboratory and the National Center for Atmospheric Research asked when gushing oil might exit the Gulf, where it would go and how diluted it’d be, up to a year later.

Thousands of tiny systems called atomic nuclei – specific combinations of protons and neutrons – prove extremely difficult to study but have big implications for nuclear stockpile stewardship. To describe all of the nuclei and the reactions between them, a nationwide collaboration is devising powerful algorithms that run on high-performance computers.
