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 found early evidence that Ayahuasca, a ceremonial psychedelic brew used by Amazon tribes for centuries, could help treat eating disorders.Continue reading Can Ayahuasca Feed Your Spirit?→
Within every object on Earth lies concealed a positive or a negative electric charge. From the very structure of the atom to the essential functioning of our brains, the natural power of electricity is all around us, and it is one of the most potent symbols of our Modern World. Making the story of electricity, the story of life itself… Continue reading The Spark of Being – A Not-So-Brief History of Life and Electricity→
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.
Sarin is a deadly compound. Colourless, odourless, and fatal even at low concentrations. A new drug designed to fight against the deadly effects of organophosphorous nerve agents, like sarin, is in sight. Continue reading Compound Interest: An Antidote to Sarin→
We live on the ever-changing planetary surface of Earth. Now, the Smithsonian National Museum of Natural History’s “Eruptions, Earthquakes, & Emissions” (“E3”) web application reveals a time-lapse animation of the data held on volcanic eruptions and quakes on Earth since 1960. The dynamic Earth at one glance! Continue reading Fifty Years of Turmoil in One Minute – The Recent Living Respiring Dynamic Earth→
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→
It comes at you as a breeze. As a gust. As a gale. Or in the scariest of situations as a hurricane or a tornado with wind speeds of up to 400 kilometres an hour. But what is wind?
A revolution in the treatment and understanding of clinical depression may be looming. And specialists are already talking about one of the strongest discoveries in psychiatry for the past two decades. For the 350 million people who suffer from the illness worldwide, this could potentially mean light at the end of the proverbial tunnel. Continue reading Looking on the Bright Side of Clinical Depression→
Prior to the discovery of nociceptors in 1906, scientists believed that animals were like mechanical devices that transformed the energy of sensory stimuli into motor responses. Pain is one of those stimulated reactions, but it is unlike other sensations. What is the purpose of pain?Continue reading Ouch!! #$@*!! – We Take a Quick Look at the Neuro-Physics of Pain→
The World population has grown to 7 billion, and it is expected to reach over 9 billion by 2050. In the long-term, this growth is unsustainable, as vital resources are becoming increasingly depleted and humanity faces a number of threats to its continued expansion. Many believe that scientists will solve these problems with new technology. Are humans causing the sixth mass extinction? What is the reality? Continue reading In the Midst of the Sixth Mass Extinction…→
There is one essential difference between living things and inanimate clumps of carbon atoms. From an all-physical point of view, the former tend to be so much better at capturing energy from their environment and dissipating that energy as heat. At MIT, Jeremy England derived a mathematical formula that he believes explains this capacity. Continue reading A Theory of Life… The Physics of Cells and Macroscopic Irreversibility→
