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?
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→
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→
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?→
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?→
Goofball, candy, ice, crack, snow, weasel dust, Belushi, Charlie… High in the Andes of South America, Erythroxylum coca grows as a shrub. For 2,500 years at least, its leaves have been known and used for their stimulant properties. Over 5 million people use cocaine and its derivatives in the United States alone. Continue reading We Do Science on Crack… with Cocaine and the Blood-Brain Barrier→
This blog is cool. It’s spontaneous! It’s electric!! But not as cool as it has been at these cutting-edge laboratories on the outskirts of Europe. Scientists there are dealing with an entirely new type of solid matter – ‘spontelectrics’.Continue reading What’s the Matter… with Spontelectrics?→
Following World War I and World War II, at least three major powers disposed of massive quantities of captured, damaged and obsolete chemical warfare material by dumping them into oceans, seas and lakes around the globe. Mustard gas, phosgene, lewisite… Submerged chemical ammunitions pose very serious ongoing environmental problems. Continue reading What Lies Beneath – The Toxic Legacy of Post-War Ammunitions Sea Dumping→
In the run-up to the 2015 physics Nobel prize, which was awarded on Tuesday 6 October, Physics World looked at how Nobel-prize-winning physicists have been moving around the globe over the past century. Continue reading Physics Without Frontiers…→
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→
