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 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.
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→
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→
There are 1.3 billion cubic kilometres of water on Earth. Nevertheless, ready access to clean drinking water remains a major issue for millions of people. A much sought-after innovation was developed by a UK-based team of researchers who created a graphene-based sieve capable of removing salt from seawater. The new technology could aid millions around the World.
The Sentinel satellite program was designed to replace the older Earth observation missions, which have reached retirement or are nearing the end of their operational life span. The satellite array will ensure a continuity of data, so that there are no gaps in ongoing studies. Continue reading Sentinel Is Watching→
Many places in the World have limited sources of drinkable water, whether it is because of limited rainfall or because of polluted water resources. Without sufficient potable water, the health of possibly billions of people remains at risk. In Lima, Perú, a simple technology helps people harvest water from the fog. Continue reading The Fog Harvesters of Lima, Peru→
It’s cold down there. Icy cold. It’s dark. Pitch black, in fact. And the crushing pressures make the deepest parts of the oceans into some of the most hostile places on our planet. The lowest of the low. The deepest of the deep. Only three human explorers ever made it down there. As a brand new wave of deep-sea exploration begins, we look at the mysterious world where marine scientists will be diving into… Continue reading Sailing the Lower Midnight… – The Uncharted Frontier of Modern Deep-Sea Exploration→
