Five years after the Chelyabinsk asteroid impact, a three-in-a-century event happens again over the Bering Sea. And almost no-one notices. I say “no-one”… but the Earth is a planet under constant scrutiny. Continue reading Large Asteroid Impacts Earth…→
The fields of Senegal are at the centre of a controversial battle against deadly malaria. With mosquitoes increasingly resistant to insecticides, and the parasite’s developing resistance to conventional remedies, the humanitarian emergency becomes ever more pressing worldwide. A plant genus could be the answer: Artemisia. But that goes against the wishes of the WHO…
The Chernobyl nuclear disaster left behind a highly toxic landscape. Thirty-two years hence, the area around the Ukrainian ghost town of Pripyat largely reverted to forest. Despite the contamination, wildlife gradually took over. Hints of recovery emerged as animal species began to thrive, free from the disruptive influence of human activity. And for the first time, researchers recorded evidence of a young wolf boldly venturing away from the danger zone.
The Universe never sleeps. Every now and then, the night sky presents us mere mortals with some heavenly spectacle. A Bonnie Tyler moment. This Friday, the Moon will enter the catwalk dressed in red to accomplish its otherwise normal nightly travel around the Earth. For one night only. A strange and rare celestial sight at dusk – a total lunar eclipse. Continue reading Crimson Moon – A Total Lunar Eclipse→
Viewing tiny objects, like cells, under a microscope is a real game of hide-and-seek with the light. It follows that the specimen must be carefully prepared, or ‘mounted’ on a slide. Here we get a little closer to the eukaryotic cell. The building block of life itself… Continue reading Life Under The Microscope→
The Scottish coast is renowned for the wealth of its rocky features. And if you can’t abide Geology, you can while away the hours with the local marine biology. It’s dead quiet and if you’re lucky on a clear day, you might even see Arran magically emerge from the mist across the waters of the Clyde estuary.
Our environment is permeated by radiation, present around us at all time. We are constantly exposed to radioactivity from natural sources for the most part naturally occurring radioactive nuclei in rocks and cosmic rays – the ‘background’. Without ado, this is my lowdown on radioactivity.
Mercury is rising. And in many more ways than one. As global temperatures go up, the Arctic ice is melting. Sea level rises. Carbon dioxide is released into the atmosphere. But below the permafrost, another threat is lurking.
Scientists accomplish the impossible. This time, a quantum physicist has only managed to capture the photographic image of an atom with a conventional camera. And THIS is the photograph….. Continue reading And THIS… is an Atom!→
Observing Negative Mass at Washington State University
Negative mass has always been theoretically possible, and the concept has finally made it from a mathematical idea on paper to a reality achieved in the lab. Scientists at Washington State University have created a fluid with negative mass. Continue reading The Bizarre Behaviour of Negative Mass→
