It’s difficult to know what birds ‘think’ when they fly, but scientists in Australia and Canada are getting some remarkable new insights by looking inside birds' heads.

Evolutional biologists at Flinders University in South Australia and neuroscience researchers at the University of Lethbridge in Canada have teamed up to explore a new approach to recreating the brain structure of extinct and living birds by making digital ‘endocasts’ from the area inside a bird skeleton’s empty cranial space.

A team of researchers led by Emory’s Chunhui Xu recently found that heart muscle cells can grow -and survive in the microgravity environment of space. Her findings, published in Biomaterials, show promise for developing hardier heart cells that could effectively repair damaged hearts in cell therapy –  the process of transplanting millions of heart cells to repair damaged hearts – on earth.

Astronomers previously thought all FRBs were generated by magnetars formed through the explosions of very young, massive stars. But new FRB is pinpointed to the outskirts of 11.3-billion-year-old galaxy without young, active stars — calling those assumptions into question. “Just when you think you understand an astrophysical phenomenon, the universe turns around and surprises us," researcher says.
