Scientists learned recently that fish was the main source of protein for people in southern Scandinavia many thousands of years ago. They also ate other animals that live in the water. The findings come from Lund University in Sweden. Scientists there tested ancient human bones from more than 80 individuals. Read more.
If you were hunting for alien intelligence, looking for a surefire signature from across the Universe of their activity, you’d have a few options. You could look for an intelligent radio broadcast, like the type humans began emitting in the 20th century. You could look for examples of planet-wide modifications, like human civilization displays when you view Earth at a high-enough resolution. You could look for artificial illumination at night, like our cities, towns, and fisheries display, visible from space.
Or, you might look for a technological achievement, like the creation of particles like antineutrinos in a nuclear reactor. After all, that’s how we first detected neutrinos (or antineutrinos) on Earth. But if we took that last option, we might fool ourselves. Earth created a nuclear reactor, naturally, long before humans ever existed. Read more.
Just like a teenager wanting to be older, volcanoes can lie about their age, or at least about their activities. For kids, it might be little white lies, but volcanoes can tell big lies with big consequences. Read more.
Nuclear power is so amazing even its waste is enormously beneficial.
Frankenstein, 200 years old this year, can still be read as a relevant warning. It is a warning against modern technology. In Mary Shelley’s novel, we read about a young, intelligent scientist, Dr. Victor Frankenstein, who creates a friend for himself, but who then recoils when he sees that his creature has come to life. That creature ultimately becomes a monster that chases his inventor and kills his sister and bride. The message it impresses on many readers, then and now, is: don’t meddle with nature; don’t go too far.
Now, let’s talk about nuclear waste, considered by many as a painful accident of modern technology. What do you think when you hear that term? Do you think nuclear waste is a product of human arrogance? Do you wish we had never started with all this nuclear technology? Perhaps it makes you feel uncomfortable just to think about the fact that nuclear waste exists on this planet.
Let’s be frank: you’re a little afraid of it, aren’t you? Read more.
An unprecedented combination of experimental nuclear physics and theoretical and computational modelling techniques has been brought together to reveal the full extent of the odd-even shape staggering of exotic mercury isotopes, and explain how it happens. The result, from an international team at the ISOLDE nuclear physics facility at CERN1, demonstrates and explains a phenomenon unique to mercury isotopes where the shape of the atomic nuclei dramatically moves between a football and rugby ball.
