The Sentinel satellite program was designed to replace the older Earth observation missions, which have reached retirement or are nearing the end of their operational life span. The satellite array will ensure a continuity of data, so that there are no gaps in ongoing studies. Continue reading Sentinel Is Watching→
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→
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→
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→
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→
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!→
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→
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→
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→
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→
Fossil Fuel Emissions Threatens Carbon Dating Accuracy
The radiocarbon14C dating method has been used for decades to accurately determine the age of a wide range of artefacts. But our relentless use of fossil fuels has pumped a type of carbon into the atmosphere that is starting to confuse the dating technique. By 2050, scientists warn, new fabrics could have the same radiocarbon date as items 1,000 years old! Continue reading The Future of RadioCarbon Dating – And an Overview of the AMS Technique→
