Weekly: Big Nobels for tiny science; how Earth might make water on the Moon; the head-scratching mathematics behind your favourite puzzles
#218
The 2023 Nobel Prize winners have been announced. Winners of the science prizes include two scientists who helped develop mRNA vaccines, physicists who’ve managed to generate ultra-short pulses of light to study electrons and chemists who’ve made unimaginably tiny crystals, called quantum dots. Why all these discoveries have touched our lives – and how one almost didn’t happen.
We’ve got some science-based puzzles that’ll have you scratching your head… Rob Eastaway, the man behind New Scientist’s Headscratcher puzzle column, has helped author a new book of brain teasers, aptly named ‘Headscratchers’. To celebrate its launch, Rob shares a tricky clock-based puzzle to try your hand at – plus a chance to win a free copy of the book.
From SpaceX to Amazon to OneWeb, the race is on to launch thousands of satellites into space, capable of providing internet access to almost anywhere in the world. But at what cost to the environment? The first study comparing the carbon footprint of these satellites is out now.
Plus: How electrons from Earth may be influencing the creation of water on the moon, why chicken hatcheries in Europe are starting to sex-test unhatched chicks and why hippopotamuses are so bad at chewing their food.
And a plug for our favourite feast of the year: Fat Bear Week.
Hosts Timothy Revell and Christie Taylor discuss all of this with guests Clare Wilson, Alex Wilkins, Rob Eastaway, Jeremy Hsu and Corryn Wetzel. To read more about these stories, visit newscientist.com.
