A Genetic Checkup: Lessons from Huntington Disease and Cystic Fibrosis
Ricki Lewis | Oct 19, 2003 | 9 min read
Thom Graves Media While genome sequencing may be the new kid on the block--perhaps now with a cracking voice and fuzzy facial hair--predicting phenotypes is the stuff of classical genetics, honed on the rare single-gene disorders, such as Huntington disease (HD) and cystic fibrosis (CF), which dominated the field in the last century (see Genetic Testing Timeline). "Geneticists today are portrayed as soothsayers of the future. But predictive medicine and testing has a significant history," says

Genetic Mutations Can Be Benign or Cancerous—a New Method to Differentiate Between Them Could Lead to Better Treatments
Ryan Layer, The Conversation | May 27, 2022 | 5 min read
Tumors contain thousands of genetic changes, but only a few are actually cancer-causing. A quicker way to identify these driver mutations could lead to more targeted cancer treatments.

Does Science Support Lifting School Mask Mandates?
Rachael Moeller Gorman | Feb 28, 2022 | 10+ min read
The CDC has given the OK to lift indoor mask mandates in much of the US, and a growing number of states no longer require face coverings in schools. But most experts agree that masks slow school spread of SARS-CoV-2, and whether now is the right time to allow teachers and students to unmask is a matter of debate.
