Tear down the middle school geology posters: We have an update. A team at Australian National University (ANU) has found evidence of a new fifth layer to the planet, an iron-nickel alloy ball in the inner core. The scientists found the hidden core by studying seismic waves that travel up to five times across the Earth's diameter – previous studies only looked at single bounces.

How do we engineer and innovate for a better world? That's the question that scientists are trying to answer, with the help of R&D investment.

MS-23, the Soyuz spacecraft Russia sent to bring cosmonauts Sergey Prokopyev and Dmitry Petelin and NASA astronaut Frank Rubio back to Earth, has arrived at the International Space Station. Per Space.com, Russia’s Roscosmos Space Agency announced early Sunday morning that the unmanned vessel docked with the ISS at 7:58PM ET on Saturday evening.
