Unexpected Elements

Nobel prizes this week went to a range of discoveries that you might be familiar with, in fact you might be using one of them right now – the lithium ion battery. The scientists credited with its Invention got the chemistry prize. And the tantalising prospect of life on other planets plays into the physics prize win. We see what salamanders have to offer in the treatment of arthritis. Human life e...

This week’s IPCC report on the state of the world’s climate looks very much like their earlier reports on the subject. The document cautiously expresses a picture of a future with greater climate extremes. Activists are frustrated by the lack of action. We look at why the scientific message is often hampered by politics. Fish could provide micronutrients to the world poor, but as we’ll hear this w...

Staying indoors might seem a good way to avoid air pollution, but scientists studying the fires in Indonesia have found there is little difference between the air quality in their hotel room and the atmosphere outside. Both levels are high enough to be considered dangerous for human health. To add to the problem, fires continue to burn underground in the peaty soil long after they were started. In...

Scientists know very little about the first few days of the life of a human embryo, once it's been implanted in the womb. Yet this is when the majority of pregnancies fail. Professor Magdalena Zernika-Goetz at Cambridge University is a leader in the field of making 'model embryos' in both mice and humans. Model embryos until now have been grown in the lab from donated fertilised eggs, but these ar...

An isotopic fingerprint is reported of a nuclear explosion in Russia last month. Researchers ask people living in the area or nearby to send them samples of dust or soil before the radioactive clues therein decay beyond recognition. Also, a near miss between an ESA satellite and a SpaceX Starlink module in crowded near space strengthens the case for some sort of international Space Traffic Managem...

A computer processor made of carbon nanotubes is unveiled to the world. Also, the continuing quest for nuclear fusion energy, and the stats on crocodile attacks since the 1960s. Satellites have transformed our lives, giving us digital communications, navigation and observations of Earth, and even an artificial place to live above the atmosphere: The International Space Station. But, would more of...

As fires across the amazon basin continue to burn, we speak to the researchers watching from space and from the ground. Also, new pictures back from the surface of asteroid Ryugu thanks to Germany’s MASCOT lander, part of the Japanese Hyabusa2 mission, give insights into the clay from which the solar system was originally formed, and Greenland’s top geologist gives his valuation of his native isla...

Scientists this week are on expedition around the volcano Anak Krakatoa, which erupted and collapsed in 2018 leading to the loss of some 400 lives on the island of Java. The scientists, including David Tappin and Michael Cassidy, are hoping that their survey of the seafloor and tsunami debris will allow them to piece together the sequence of events, and maybe find signs to look out for in the futu...

A new undersea volcano has appeared off the coast of East Africa. The sea floor between Madagascar and Mozambique has become increasingly seismically active in the last year. As well as the appearance of this active volcano, local islands are now experiencing frequent earthquakes. The causes of Indonesia’s Palu Bay tsunami last year are being examined thanks to social media. Videos taken as the ts...
