Starting with microbes, Harvard-MGH researchers outline a devastating chain of events

A new Harvard study shows that people create visual images to accompany their inner speech even when they are prompted to use verbal thinking, suggesting that visual thinking is deeply ingrained in the human brain.

Much of life is beyond our control, but dining smartly can help us live healthier, longer

Speaking at a Climate Week symposium, former EPA administrator Gina McCarthy urged an audience of climate scientists and health experts to speak out about climate change.

Research suggests that genetic sequencing technologies should be used to screen for mutated cells in stem cell cultures, so they can be excluded from scientific experiments and clinical therapies.

For the first time, researchers describe the types of cells generated in brain organoids, networks of nerve cells, and show the greater diversity, complexity, and response to stimulation developed for nine months and longer.

To grow old well requires minimizing accidents, such as falling, as well as ailments
