Our 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.
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.
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…..
No need to be an atomic scientist, when you’re considering the state of the World today, to understand the picture is an alarming one. Allegorically-speaking, the Earth is now only two minutes away from impending catastrophe.
On the whole, Earth scientists agree that melting of land ice greatly contributes to sea-level rise. And one thing’s for sure. Future global warming will exacerbate the risks posed to human civilisation. But… What if you could forecast major floods? You can.
A large chunk of the Pine Island Glacier has broken free today, the media announced. The giant iceberg is estimated to cover an area of roughly 6,000 km2. About a quarter the size of Wales in the United Kingdom.
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…
Observing Negative Mass at Washington State University
Negative 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.
If the Forest Won’t Come to the Experiment, Why Not Bring the Experiment to the Forest?
The role that plants play in absorbing carbon dioxide is one of the great unknowns of climatology. Now, an industrial-scale experiment in a Staffordshire forest has been designed to help fill gaps in our knowledge about climate change.
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.
The Arecibo observatory is a very large radio telescope located in Puerto Rico. In 1974, astronomers used it to broadcast a message into outer space intended to demonstrate human intelligence. Why are we so interested in finding intelligence in the stars, and yet so deaf to the many species who manifest it here on Earth?
As the X-Files series enjoy a revival on TV, the American spy agency has decided to place thousands of declassified documents detailing government research into UFOs on its website. The CIA documents also confirm the reality of humans with ‘Special Abilities’ able to do seemingly impossible things.
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.
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!
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.
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.
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…
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.
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.
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?
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…
