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.

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.
Just like buses, it seems. But even rarer and a damn sight more exciting to be honest. Ooohoo!!! Out with your old Science books!! HeL-LOOooo elements 113… 115, 117 and 118!!
Continue reading You Wait Ages for a Chemical Element, and Then… BINGO!!
Finches in the Galápagos Islands are being threatened by a parasitic fly that attacks their young, placing the same species of birds that helped Charles Darwin refine his theory of evolution in danger of extinction. But the authors of a new study say that human intervention could alleviate the risk.

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?

The days of Professor Challenger are here. This week, scientists have set out to drill deeper into the Earth’s mantle than has ever been done before. This time, let us hope the World will not scream!
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’.
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.

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…

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.

Modern-Day Hipsters Take Heed…With his wind-swept mane, the inimitable Richard Feynman looked devilishly handsome. And he darn-diddly knew it too! As for Fritz Haber, Rosalind Franklin and Neil deGrasse Tyson, they were the original hipsters. That’s according to BuzzFeed anyway… Continue reading Proving that Physicists were the Original Hipsters
I met Cortana mid-afternoon. The perfect time for a well-earned tea break and a chat down at the local café. I was keen to meet Cortana for the first time. By then, she was already a celebrity.

Astronomers have found the smallest exoplanet yet to be directly photographed by a telescope on Earth. A methane-shrouded gas giant. A young Jupiter…

The radiocarbon 14C 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!
First predicted in the 1960s, like the Higgs boson before it, the pentaquark eluded science for decades until its recent detection at CERN’s LHCb collaboration. The discovery amounts to finding a new form of matter…
Taking a radically different experimental approach, EPFL scientists were able to take the first ever snapshot of light behaving simultaneously both as a wave AND as a stream of particles. You need light to take a photograph. But how do you take a photograph of light?

1/60 minute. 1/3,600 hour. 1/86,400 day. 1/1 hertz. The duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of a 133 55Cs caesium isotope corresponds to one second. But what does it look like? And where might you find a second?

Deep down, in huge subterranean caverns… Underneath the Franco-Swiss border… 300 feet underground… lies a beast of unprecedented power… and mystery. The Large Hadron Collider (LHC) that man summons to explore the uncharted corners of the sub-atomic realm… After two years of a deep slumber, the mighty beast has awoken…

The Standard Model of Particle Physics describes the fundamental particles and their interactions via the strong, electromagnetic and weak forces, providing precise predictions for measurable quantities that can be tested experimentally. Here’s the latest!! It’s hot!!! It’s exciting!!! At least, if you’re a particle physicist…

One of the all-time most interesting elements in the Periodic Table, nitrogen is a colourless, odourless, inert diatomic gas that makes up to 78% of the Earth’s atmosphere. We breathe it everyday, although an atmosphere of pure nitrogen is nefarious to animal and human life. It is vital to life and plants simply strive on it. Nitrogen compounds are explosive, and nations have gone to war over it. It can feed… or kill.

This is the Jasper Project. Over 325,000 photovoltaic panels capable of producing 180,000 MWh of clean energy every year and support the needs of almost 80,000 households. More and more solar farms are being built across Africa. Solar energy is on the rise.

A ground-breaking one-year space mission involving twin astronauts Mark and Scott Kelly should help doctors, scientists and mission planners better understand the physical and psychological impacts of a long-duration spaceflight.

On 20th March 2015, the Moon will pass in front of the Sun and exactly block out most of its light. It will be the first total solar eclipse of the 21st century that is visible from the northernmost regions of Europe…

Take one second and divide it a million times. Then, take one millionth of that second and divide it again… by a billion! All you’re left with is a femtosecond. That’s how fast the Linac laser at Palo Alto can deliver burst of X-rays and track chemical reactions in living systems… as they happen.
