… And Hardly Anyone Notices!Five years after the Chelyabinsk asteroid impact, a three-in-a-century event happens again over the Bering Sea. And almost no-one notices. I say “no-one”… but the Earth is a planet under constant scrutiny. Continue reading Large Asteroid Impacts Earth…
The Chernobyl nuclear disaster left behind a highly toxic landscape. Thirty-two years hence, the area around the Ukrainian ghost town of Pripyat largely reverted to forest. Despite the contamination, wildlife gradually took over. Hints of recovery emerged as animal species began to thrive, free from the disruptive influence of human activity. And for the first time, researchers recorded evidence of a young wolf boldly venturing away from the danger zone.
The Infinitesimally SmallViewing tiny objects, like cells, under a microscope is a real game of hide-and-seek with the light. It follows that the specimen must be carefully prepared, or ‘mounted’ on a slide. Here we get a little closer to the eukaryotic cell. The building block of life itself… Continue reading Life Under The Microscope
Natural RadiationOur environment is permeated by radiation, present around us at all time. We are constantly exposed to radioactivity from natural sources for the most part naturally occurring radioactive nuclei in rocks and cosmic rays – the ‘background’. Without ado, this is my lowdown on radioactivity.

As Permafrost Melts…Mercury is rising. And in many more ways than one. As global temperatures go up, the Arctic ice is melting. Sea level rises. Carbon dioxide is released into the atmosphere. But below the permafrost, another threat is lurking.
Continue reading Mercury Rising – Climate Change and the Arctic Permafrost
‘Single Atom in an Ion Trap’Scientists accomplish the impossible. This time, a quantum physicist has only managed to capture the photographic image of an atom with a conventional camera. And THIS is the photograph….. Continue reading And THIS… is an Atom!
Art in a New LightThe World’s only particle accelerator dedicated to analysing artworks is back online at the Louvre Museum in Paris. Continue reading Shedding Light on Art – A Particle Accelerator in Paris
Open For ScienceAt the heart of central London, opposite St Pancras’ International station, stands the new Francis Crick Institute – a working building with distinctive ultra-modern architecture. Important science is being done here. Life-changing science. Continue reading The Francis Crick Institute – Open For Boundless Scientific Discovery
A Plastic Tide10 rivers on Earth may be responsible for around 90% of oceanic plastic pollution in the World. Continue reading Ten Rivers on Earth – The Great Plastic Tide
Fingerprint spectrometry analysis – a technology which can detect the brand of hair gel or condom used by a suspect – could soon be admissible as evidence in UK courts. Continue reading Fingerprint Forensics Delve Deeper Into Spectrometry Analysis
The Xi-cc++ ParticleCERN’s LHCb collaboration has announced the discovery of a new “charming” particle, thought to be instrumental to the strong force – the Xi-cc++. Another particle. So…? Continue reading Charming New Particle Xi-cc++ Discovered at CERN
Omnipresent Electricity Within every object on Earth lies concealed a positive or a negative electric charge. From the very structure of the atom to the essential functioning of our brains, the natural power of electricity is all around us, and it is one of the most potent symbols of our Modern World. Making the story of electricity, the story of life itself… Continue reading The Spark of Being – A Not-So-Brief History of Life and Electricity
Observing Negative Mass at Washington State UniversityNegative mass has always been theoretically possible, and the concept has finally made it from a mathematical idea on paper to a reality achieved in the lab. Scientists at Washington State University have created a fluid with negative mass. Continue reading The Bizarre Behaviour of Negative Mass
Making Seawater Safe to DrinkThere are 1.3 billion cubic kilometres of water on Earth. Nevertheless, ready access to clean drinking water remains a major issue for millions of people. A much sought-after innovation was developed by a UK-based team of researchers who created a graphene-based sieve capable of removing salt from seawater. The new technology could aid millions around the World.
Continue reading All of the Water on Earth – A Graphene-Based Sieve for Desalination
The Sentinel ConstellationThe 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
Meat and Potato Pie in the SkyA meat and potato pie has been attached to a weather balloon, and sent “into space”… Continue reading Pie in the Sky
Fog HarvestersMany 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
Improving on Nature’s PhotosynthesisAgronomic engineers have managed to improve upon one the most important biological process on the planet – photosynthesis. The increased yield in crop could be as much as 15%. Continue reading Feeding of the Nine Billion – The Future of Photosynthesis and Increased Crop Productivity
Visualizing Dynamic EarthWe 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
What lies 5,000 metres Below Sea Level?It’s cold down there. Icy cold. It’s dark. Pitch black, in fact. And the crushing pressures make the deepest parts of the oceans into some of the most hostile places on our planet. The lowest of the low. The deepest of the deep. Only three human explorers ever made it down there. As a brand new wave of deep-sea exploration begins, we look at the mysterious world where marine scientists will be diving into… Continue reading Sailing the Lower Midnight… – The Uncharted Frontier of Modern Deep-Sea Exploration
What is Your Poison of Choice?Be honest. We all have one. What’s your poison? Booze, tobacco, prescription drugs… or something a little more exotic? Cannabis is a controversial plant, regarded by many as a godsend. If Carlsberg made a ‘erb… Continue reading Panacea Nostrum – The Forensic Toxicology of Cannabis
Meet LISA!Erm…No. Not Mona Lisa! (Rolls eyes.) Think again!! This is LISA – the Lisa Pathfinder satellite, the key element for a grand new project: a space-based gravitational observatory. Continue reading Hunting Ripples in the Fabric of Space-Time – The Trials and Tribulations of LISA
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
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. Continue reading We Consider Human Network Physiology and Medicine – The “Body Electric” – Part Deux
“It’s Life! But Not as We Know it…”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
