Just over a century ago, Einstein proposed the existence of waves in the spacetime continuum – the logical deduction from his Theory of General Relativity. In February 2016, scientists finally announced the detection of those “ripples” in gravity, using the technique of laser interferometry. Continue reading 2016: Another Year in Cutting Edge Science→
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→
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→
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 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?
Welcome to Jurassic Skye! While dinosaurs might be long dead and no threat to puny humans, the rich fossil record of the Scottish island of Skye – the “Misty Isle” – has provided palaeontologists with important clues to the lives of prehistoric predators and their preys. Continue reading Fantastic Beasts of the “Misty Isle” – Welcome to Jurassic Skye!→
The term ‘Anthropocene’ has entered scientific literature as an expression of the fundamental environmental change caused to planet Earth by humankind, despite not being a formally defined geological unit within the geological time scale. The hunt is on for the “golden spike” – a marker for future researchers to point to in millions of years and identify as the geological start of the Anthropocene epoch. Continue reading Human versus Nature – The Golden Spike of the Anthropocene→
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→
They are made from assemblies of multiple elements fashioned from composite materials, like metals or plastics. And they promise to revolutionise the way we look at things. Continue reading Optically Brilliant Metamaterials→
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→
Once a chic resort on the Bay of Naples, Herculaneum was favoured by the finest of Roman’s elite society, who spent the hot Italian summers there… until a catastrophe struck one afternoon in 79 AD. The Villa dei Papiri, excavated centuries later, was found to contain the only library to have survived from the Classical World – a unique cultural treasure, which the eruption of Mount Vesuvius nearly destroyed, and yet preserved all at once. How do you read what is essentially a charred book? Continue reading Between the Lines of the Herculaneum Papyri using X-Ray Imaging Techniques→
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→
