Visual summaries of stories worth understanding in technology, business, and science. We find what’s interesting, explain what happened, and link to the sources.
One head, two origin stories. Stanford-led research suggests the forebrain and midbrain develop separately from the hindbrain—a finding that helped researchers grow human hindbrain motor neurons in the lab.
Even galaxies struggle to get everyone moving in the same direction. NASA’s new Hubble image highlights NGC 4698, whose central stars and gas rotate perpendicular to the surrounding disk.
A careful course correction can be worth years. NASA says fuel savings and extra propellant could give the Roman Space Telescope at least 22 years of potential science operations, against its original ten-year fuel budget.
