According to legend, physicist Werner Heisenberg formulated the mathematics behind quantum mechanics in 1925 while on a restorative trip to the remote North Sea island of Heligoland.

To celebrate the centenary of this event, several hundred researchers have descended on the island to take part in a conference on all things quantum physics. Nature reporter Lizzie Gibney was also in attendance, and joined us to give an inside track on the meeting.

Researchers have developed a soft electronic implant that can measure brain activity of amphibian embryos as they develop. Understanding the neural activity of developing brains is a key aim for neuroscientists, but conventional, rigid probes can damage growing brains. To overcome this, a team have developed a flexible mesh that stretches with the brain and tested it by monitoring single neuron activity during development of frog and axolotl embryos. More testing and ethical considerations will be required, but the researchers hope that eventually such implants could help with neurological conditions that affect humans.

By combining AI tools with mechanical engineering techniques, a researcher has developed a new way to speed up the restoration of damaged paintings. The technique creates a removable mask that can be overlaid onto a painting to cover any damage apparent in the artwork. It was successfully tested on an oil painting, fixing a large number of damaged areas in only a few hours. This could offer a significant speed-boost to painting restoration, which can often take months, or even years.

In this Podcast Extra, we examine President Donald Trump's calls for NASA to land humans on Mars. Although the White House has proposed spending some US$1 billion in 2026 on Mars plans, critics say the final cost will likely be hundreds of billions of dollars spread over a number of years.

This call comes amidst plans to drastically reduce NASA's funding, and the proposed cancelling of dozens of the space agency's missions, including projects to study Earth, Mars and Venus.
