Cooling atoms may seem like a strange idea, especially when lasers are used for that purpose. CNRS News revisits scienceâ€™s best find for measuring time with accuracy, confirming fundamental physical theories, and studying certain exotic properties of matter.
The recent discovery in Saudi Arabia of large animal sculptures has prompted a team of researchers to study these ancient low- and high- rock reliefsâ€”exceptional by their size and artistic qualityâ€”and shed light on the evolution of rock art in this region.
All life on Earth exists on a thin layer that surrounds the planet. To better understand this so-called "critical zone," researchers are setting up state-of-the-art instruments and creating open-air laboratories all over the world. We take you on a guided tour of one of these environmental observatories in France.
Archaeology In the Greek cities of antiquity, a lottery system was devised to select citizens for public duty. For the first time, researchers were able to build a stone replica of a kleroterion, the amazing machine that made this random selection possible.Â
Engineering What advantages does hydrogen have that could make it a key component of our future energy mix? What are the obstacles to be overcome? Daniel Hissel, a respected hydrogen specialist and recent winner of the prestigious Blondel Medal, shared an update on the topic at an international conference on...
Literature The correspondence of the French writer Marcel Proust, a trove of thousands of letters in countless locations around the world, is the focus of a massive digitization program uniting French and US researchers.

Biology Why does a disease affect one gender more than the other? Why is autism misdiagnosed in women? Sociologist Mathieu Arbogast, project manager at the CNRS's Mission for Women's Integration, explains the importance of gender-related social relations to health issues.
Neuroscience Do we really only use 10% of our brains? Although many people believe it, there is absolutely no scientific evidence backing this claim. So why is neuroscience often prone to misinterpretation?
bioengineering Microalgae could become an alternative to oil, a source of edible protein, while also recycling carbon dioxide. They could provide a sustainable and environmentally-friendly solution to our development needs. But how can we scale up their production and optimize the extraction process of their...
Chemistry Every year, huge amounts of explosives are used worldwide to build roads, extract minerals, or put satellites into orbit. Yet the processes currently in use disperse large quantities of lead into the environment. Chemists have just found a much less polluting alternative.
