Even though it doesn't show much, we got our first look at the baby today. It's at 6 weeks, 5 days, and doesn't look recognizable yet. It's the small white shape inside the big black shape.

Medical researchers at CalTech and the Children's Hospital in Los Angeles have successfully inhibited cancer growth in mice by wrapping engineered RNA in nanomaterials and introducing them into the bloodstream. Two polymers and a special coating allow the therapeutic RNA to enter the cancer cell and release the therapeutic RNA payload. The new technique has slowed or prevented the development of secondary tumors in lab mice with Ewing's sarcoma. Further testing is planned on humans, and with other cancers.
