VIDEO: Scientists have captured live video of parts of the most fundamental event in biology — cells reading and copying DNA instructions to make proteins
Robot researcher Mark Yim offers a look inside the promising field of modular reconfigurable robotics — bots that can shift form to tackle an array of tasks
Scientists are finding that microscopic membranous bubbles called extracellular vesicles transmit messages from cells and do big jobs in many areas of biology — plus they might be useful for therapies.
Only recently have scientists directly witnessed this most pivotal of events in biology, thanks to new technology that allows them to observe the process in living cells. It’s teaching them a lot.
Returning to designs abandoned in the 1970s, start-ups are developing a new kind of reactor that promises to be much safer and cleaner than current ones.
In an evolving branch of forensic science, genealogists help solve crimes, sometimes identifying suspects with the DNA of distant relatives they’ve never met. As cold cases yield, concerns about privacy issues persist.
