Molecule dashes hopes for interstellar signs of life

Loading player...
Astronomers are trying to understand where our solar system came from, how life got started here, and where else in the galaxy life may be lurking. Chemistry is very important in these processes both in terms of providing chemical building blocks from which things can form, but also providing chemical signatures that highlight that something - like life - is happening. We had thought that one compound, called methyl chloride, was a surefire sign of life, but now astronomers in America and Denmark have detected the same chemical around a star without any planets, as well as on a comet in our own solar system. Izzie Clarke heard from Jes Jorgensen from the Niels Bohr Institute at the University of Copenhagen how they collect this information from space

Gorilla sperm, and subversive gambling machines

This time, macho male gorillas trade stature for sperm count, how gambling machines use sound and light to take the sting out of losing, whether babies are born hard-wired to dance, the way bird eggs are adapted to altitude, and the effect of a fever on the stickiness of malaria-infected…

Sickle cell defeated malaria and opened up pastures new

Malaria has been killing humans for at least fifteen thousand years, and our DNA still carries the scars. Ninety percent of the world's malaria cases are in Africa. But this isn't just a modern health crisis. It's written into our evolutionary history. New research from the University of Cambridge reveals…

Malaria in Africa

Africa remains at the centre of the global malaria crisis. The continent accounts for around 95 percent of all malaria cases, placing immense strain on health systems and costing hundreds of thousands of lives each year. In 2023, there were an estimated 249 million cases globally, with the vast majority…
