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.
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?
Everything is connected. And so it is in the human body too. Everything in the human body is connected. No doubt that all your organs – heart, liver, lungs – work as one to keep you alive and as close as possible to a healthy state.
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.
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?
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…
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.
♫ 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.
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?
This blog is so 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’.
