how a small team created the largest mouse-embryo atlas so far

how a small team created the largest mouse-embryo atlas so far

Building an atlas of all the cell types that make up the body typically requires multinational collaborations and massive budgets. But a technique that can analyse the genetic activity of hundreds of thousands of individual cells at a time has allowed one small team to produce a time-lapse atlas of an embryonic mouse’s cells over … Read more

Rotating curved spacetime signatures from a giant quantum vortex

Rotating curved spacetime signatures from a giant quantum vortex

To experimentally realize a curved spacetime such as a black hole requires a specific relative motion between the excitations and the background medium. One-dimensional supersonic flow, the archetypal example of an acoustic black hole, provides a platform for observations of Hawking radiation in both classical20,21 and quantum fluids9,10,22. More complex phenomena such as Penrose superradiance … Read more

The warfighter

The warfighter

Cadence noticed the warfighter on her way to school. He was still there later, sitting in the tiny fenced park, as she walked back home along Sixth Avenue. There was a pigeon watching him, which the police had thought at one time was a good way to disguise a camera. She stopped and sat on … Read more

Planet-eating stars hint at hidden chaos in the Milky Way

A star in the process of consuming a planet (artist’s conception).Credit: NG Images/Alamy Stellar detectives have identified seven stars that recently dined on a rocky planet. The study doubles the number of binary stars known to have consumed a planet, and questions the perception that mature solar systems harbouring Earth-like planets are usually stable. The … Read more
