Temperature inversions are meteorological phenomena which can occur over busy cities under particular environmental conditions. Retired jet engines could be used as “virtual chimneys”, and draw upwards the resulting smog that clouds the air over some of the World’s most polluted cities. Continue reading Temperature Inversions, City Pollution and Defunct Jet Engines→
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→
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 a side of us that is not unique to our own species. Evil. Why? How did it start? The first time. Asking why evil came into existence is a valid question. Evil behaviours are categorised into four distinct groups. Of course, it gets pretty dark. But what is “Evil”? Continue reading Breaking Bad – The Evolutionary Perspective of Evil→
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→
Plant life is one of Nature’s miracles. Imagine being a plant and almost all you will ever need to keep on striving is sheer sunlight. In green plants, both photosynthesis and aerobic respiration occur. It’s a lot like the way in which the human body breaks down food into fuel that it can store. Essentially, using energy from the Sun, a plant can transform carbon dioxide CO2 and water into glucose and oxygen… Continue reading A Day in the Life of a Plant – Photosynthesis and Phytochemistry→
You know how when you throw a rock into a pool, that makes ripples in the water? And how Einstein once upon a time predicted that the very mass of stars and planets should warp spacetime? Although we have had a justified inkling that Einstein was right for quite some time, we had never before detected such a phenomenon. Until THIS happened…Continue reading The Discovery of Gravitational Waves – Merging Black Holes and Advanced LIGO→
Most of us are familiar with the idea that our bodies need calcium. And calcium is indeed the key element in our bones. Calcium is the most abundant metal in the human body – and those of animals too. The fifth most abundant element on Earth and our World’s chosen architectural building block. Yes, calcium is a metal. Do we really appreciate its true value? Continue reading Yes, Calcium is a Metal!→
We, humans, have driven environmental changes on a scale that is unique in Earth’s history. Human-driven biological, chemical and physical changes to the Earth’s system are so great, rapid and distinct that they may characterise an entirely new epoch – The Anthropocene.Continue reading Defining the Anthropocene – What is the Age of Man?→
♫ Spaceman, I always wanted you to go into space, man! ♫
After nearly five hours in space, British astronaut Tim Peake completed his first spacewalk, at 17:31 GMT on Friday 15 January. Intended to last over six hours, the space walk was cut short after his US colleague Tim Kopra reported a water leak in his helmet. Continue reading Name: Tim Peake Job: Space Electrician→
Already this article is beginning to sound like one of those sempiternal quizzes you so often get on social media… but it actually shows how science reality connects. Are you having a scientific identity crisis? Continue reading Lateral Thinking in Science – Who Are You?→
Finches in the Galápagos Islands are being threatened by a parasitic fly that attacks their young, placing the same species of birds that helped Charles Darwin refine his theory of evolution in danger of extinction. But the authors of a new study say that human intervention could alleviate the risk. Continue reading On the Evolution of Darwin’s Finches→
There is a place on Earth where lightning storms last forever. We are at Catatumbo, in Venezuela. And this year, Catatumbo was approved for inclusion in the Guinness Book of World Records, as the place in the World with the most lightning bolts per square kilometre each year at 250. What causes such a powerful storm to develop in the same spot, up to 300 nights a year? Continue reading The Everlasting Storm of Catatumbo, Venezuela→
Better than the A-Team, it’s COP21! Never have so many World leaders been in the same place on the same day. This time, they have just ten years to make a difference! Could the problems be solved? Will the World finally be saved? Continue reading COP21 – The Return Les “Entreprenieurs” in Paris→
23rd October 2015. The ‘strongest ever’ hurricane recorded in the Western hemisphere is about to make a “potentially catastrophic” landfall on the western coast of Mexico. This is hurricane Patricia. At that time, the super storm is a Category 5. Weather scientists predict 20 inches of rain and 200 miles per hour winds…Continue reading On the Trail of Hurricane Patricia→
Mars is not the dry, arid planet we once thought it was. Under certain circumstances, liquid water has been found. NASA’s announcement has the potential of turning some Red Planet theories on their heads…
A new online citizen science initiative, Fossilfinder, is inviting ordinary members of the public to help hunt for fossils in the Kenyan desert. The volunteers will have the opportunity to sift through one million images from the arid Turkana Basin – a key area for fossils of early human ancestors. Continue reading Armchair Fossil Hunting in the Turkana Basin→
With his wind-swept mane, the inimitable Richard Feynman looked devilishly handsome. And he darn-diddly knew it too! As for Fritz Haber, Rosalind Franklin and Neil deGrasse Tyson, they were the original hipsters. That’s according to BuzzFeed anyway… Continue reading Proving that Physicists were the Original Hipsters→
Once upon a time, Europe was almost covered by one giant forest. Now, it’s almost entirely fields and grasslands. Humans are controlling tree densities. Understanding the global extent and distribution of forest trees is central to our understanding of the terrestrial biosphere. Continue reading Three Trillion Trees→
Let’s talk about size… 😉 How big are the objects floating in our Universe and how big can they get? Starting with a “big” object, our very own Moon… Embark on a tour of space… A tour of our Universe… Continue reading Size Matters… in Astrophysical Terms→
