New techniques that could make germ-line genetic engineering unprecedentedly easy are forcing policy makers to confront the ethical implications of moving forward

What everyone should know about cut-and-paste genetics

Mutant mozzies could rapidly spread through wild populations

Researchers took cells from donated vocal cord tissue and successfully grew them on a three-dimensional scaffold to produce new vocal cords that can produce sound

The tissue engineering technique could someday help restore the voices of patients with otherwise untreatable vocal disorders, although more testing must be done

New gene-editing technology that successfully reprogrammed cells to fight leukemia in a 14-weeks-old infant could be applied to other cancers

Researchers are working to engineer practical devices that patients can use in their homes

Fatalities from causes like heart disease, cancer and stroke dropped 43 percent between 1969 and 2013

Implants that prop open clogged arteries and then dissolve are part of a new medical frontier

Interactive games show some success in small, preliminary studies, but scientists have reservations

Scientists restored youthful brain plasticity and vision in mice

Tech firm’s ambitious goals and abundant resources attract life scientists, most recently Harvard Medical School cardiologist Jessica Mega
