Join Sam Wong, News editor for New Scientist, Catherine de Lange, editor, and Madeleine Cuff, reporter, as they explore awe-inspiring science stories of 2024. Discover how preserved brains are easier to find than thought and the potential of seafloor metallic nodules as geobatteries. They discuss surprising findings about Dyson Spheres and alien life, dive into cultural highlights like the installation 'Breathing with the Forest', and full cheers about flowers that sequester nickel and groundbreaking frog conservation efforts. Plus, a fun quiz tests science knowledge!
The intriguing preservation of human brains after death offers insights into dementia and brain aging mechanisms.
Metallic nodules on the ocean floor not only generate oxygen but also raise environmental concerns with potential deep-sea mining activities.

Preservation of the Human Brain Post-Mortem
Research reveals intriguing insights into what happens to human brains after death, challenging previous assumptions about post-mortem decay. A study reviewed over 4,000 cases of preserved human brains, discovering that in many instances, the brains remained intact while the surrounding tissues decomposed. This phenomenon has been attributed to various preservation processes, including unique conditions found in bogs that result in a leather-like preservation. The findings open avenues for understanding brain aging and neurodegenerative diseases, suggesting that the mechanisms behind these preserved brains may mirror certain processes in conditions like dementia.
The Rise of Weight Loss Drugs
Weight loss drugs, particularly Ozempic, have gained significant attention this year, transitioning from diabetes treatments to popular solutions for obesity. Reports indicate that a substantial number of individuals, including those without weight issues, are using these medications for micro-dosing due to perceived benefits. These drugs may not only assist in weight loss but also show potential in treating a variety of health issues, such as addiction, depression, and heart health, making them a subject of broad interest. However, concerns about their long-term effects and usage patterns underscore the need for further research to examine safety and efficacy.
Discoveries in Ocean Ecosystems
A surprising discovery in the deep sea unveiled that metallic nodules found on the ocean floor play a crucial role in oxygen production for the underwater ecosystem. Research initiated by a British scientist revealed that these nodules could act as geo-batteries, generating electricity that facilitates oxygen production through a biochemical process. This revelation poses challenges for ongoing deep-sea mining interests, as extracting these nodules could potentially compromise a vital source of oxygen for marine life. Further investigations are essential to understand the full ecological impact of these findings and the implications for environmental conservation.
Searching for Signs of Extraterrestrial Life
A fascinating investigation into the stars of our galaxy suggests the possibility of detecting advanced alien civilizations through their heat emissions, known as technosignatures. Astronomers reported observing an unusual infrared heat pattern emitted by certain stars, hypothesizing connections to constructs like Dyson spheres, which advanced civilizations might create to capture their stars’ energy. This speculation ties into broader questions about the existence of intelligent life beyond Earth and the potential of overcoming barriers to find them. The implications of such discoveries could reshape our understanding of life in the universe and humanity's place within it.
In this special episode recorded live at the Science Museum in London, we celebrate some of the best, most awe-inspiring science stories of 2024.
Round one kicks off with the panelist’s stories of the year, including the discovery that thousand-year-old preserved brains are much easier to find than we realised, that metallic nodules found on the sea floor could be acting as “geobatteries”, creating oxygen in the deep sea, plus a surprising finding involving Dyson Spheres that may hint at the existence of advanced alien life.
In round two the panelists discuss their cultural highlights of the year. On the line up is an installation in London called ‘Breathing with the Forest’, a time-travel novel called ‘The Other Valley’, the stage show reimagining of ‘Dr Stangelove’ and an absurdist comedy about climate diplomacy called ‘Rumours’.
Round three is a quiz for the audience asking questions like, do warm drinks taste more alcoholic than cold ones? What animal can be added to milk to initiate the yoghurt-making fermentation process? And which animal can survive with almost no sleep?
And round four celebrates stories that will make you say “Wow!”, plus a moment of good cheer. These include flowers that can sequester nickel and be turned into metal, how brains and other body parts can be brought back from the dead, the discovery of the world’s largest coral reef and the invention of a hospital for fungal-infected frogs.
On the panel are Rowan Hooper, Catherine de Lange, Sam Wong and Madeleine Cuff.
