Geothermal energy prospectors have long used gravity meters in their search for the right subsurface characteristics. But these have been point measurements. GOCE now provides this information across the World at a resolution never before achieved on that scale.

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.

“Dark matter?” You cannot see it. But there is something there. As for what it is, it’s anybody’s guess! Dark matter does not interact with light. At all. Which makes it difficult to detect. “But if you cannot see it? How do you know it is in fact there?” Well, it does interact with gravity, and as it does so it bends the path of any light ray passing nearby...

That’s how this TED video on the Higgs boson begins. I say two guys… It’s more like one physicist working on the Large Hadron Collider at CERN – the European laboratory for Particle Physics – aka Dave Barney, and a Blues singer, aka Steve Goldfarb, in the guise of a pink slug…

Four states of matter can be seen in everyday life: solid, liquid, gas, and – somewhat more exotically – plasma. As a tightly bound combination of oxygen and hydrogen atoms, a water molecule is nothing out of the ordinary. Liquid water, steam or ice are still just water. Yet, it is intriguing to see how the very same building blocks of matter are capable of producing such broadly distinct states.

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.
You’re not having déjà vu. I already wrote about the Leidenfrost Maze in this blog. And although physics experiments fascinate many, they don’t normally weigh up as Internet clickbait. But the Leidenfrost effect is different…
Ever since Francis Crick and James Watson brought Physics and Biology together in 1953 to unveil the molecular structure of DNA, the boundary between the two disciplines has continued to become increasingly blurred. In this genomic new era, ever more principles from Physics are being applied to living systems in an attempt to understand complexity at all levels. Although sometimes the best solution to a Physics problem lies in the macroscopic world of Biology…
This mesmerising image of the Northern Lights over Scotland was captured by Baltimore-born NASA astronaut Terry Virts, a member of Expedition 42 from the International Space Station earlier this week, as it drifted over Europe.

What happened at time T = 0? is still anybody’s guess. At least, earlier observations of Planck’s radiation had suggested the first generation of stars were bursting into life by about 420 million years after the Big Bang. However, scientists from Europe’s Planck satellite mission now say the first stars lit up the Universe later than was previously thought…
At the beginning of the 20th century, the discovery of the radiometric “clock” revolutionised our understanding of the Earth’s deep history, confirming what geologists had been claiming for decades. Nevertheless, newer and more accurate dating methods posed further problems in themselves. After all, how do we know our Earth is 4.5 billion years old, and not a mere few thousands of years as suggested by the Bible?

Our planet has existed for 4.5 billion years, and it has been a busy lifetime. From amazing leaps and bounds forward into evolution to devastating asteroid impacts and other episodic extinctions, here are the biggest milestones in Earth’s history – the eventful journey that shaped our World today.
No other country on Earth has more bushfires than Australia. Bush fires spread quickly destroying everything in their path and they are extremely difficult for fire brigades to control. At the CSIRO in Yarralumla, researchers are using their Pyrotron – a combustion wind tunnel – to provide them with a unique insight into how fire behaves in the Australian bush.

A friend of mine once casually asked me over a drink: “What is entropy?” Eeek! Interesting concept. But… How do you define entropy in a non-mathematical way? How can you sum up entropy in 30 seconds? In one mental image. In a single concept… In one word. A form of energy? A measure of disorder in the Universe? Randomness? All of the above? Tricky question. And then, I dropped my glass…

… is pretty much the bemused reaction you’ll get if you allow yourself to answer casual questions about science over a drink with a non-physicist. AB-SO-LUTE disbelief. Your fault! Shouldn’t have gone there… Pretend you didn’t hear the question… Especially if the answer is ion propulsion!

We all know about diabetes, heart disease and cancer. Well, as much as any of us can learn from watching the news whether on TV or on the Web. On average, the advice is loud and clear. You’re told to: eat healthily, exercise moderately. Additionally, don’t smoke, don’t take drugs and go easy on your alcohol consumption. Overall, it makes good sense. Your heart, your lungs and your liver play a major role in keeping you alive and well. That little, everybody realises. But how much do we really know when it comes to illnesses of the nervous system? And without a healthy nervous system, well… This article deals with Multiple Sclerosis. It is an attempt to fill a gap in my own general ignorance and to inform others about this cruel condition…

GOCE succumbed to gravity – the force it had been sent up into space to study. Ironically. When the xenon fuel for this engine was exhausted, the satellite fell back to Earth in November 2013. The first of ESA’s Living Planet Programme satellites, GOCE was intended to map the Earth’s gravity field in unprecedented detail...

Florida has Cape Canaveral, and now it seems the UK city of Sheffield has a new space port dubbed “Cape Kebaberal”. The name was inspired by the favourite student food of Alex Baker and Chris Rose, who run the Sheffield-based company SentIntoSpace.

It’s not often you can see lightning above Glasgow, so this 2006 Flickr photograph is a rare and impressive sight. But that’s not the point… A study by researchers in the United Kingdom shows it is not just conditions here on Earth that determine how much thunder and lightning we get. The Sun’s magnetic field also has a major influence, more than doubling the number of lightning bolts on some days…

When Classical Physics and Post-Impressionist artists meet, few results are as hauntingly beautiful or as enchanting as one of Vincent van Gogh’s most famous masterpieces. The Starry Night embodies the inner, subjective expression of van Gogh’s response to Nature. And the churning night sky he depicted tells of the artist’s very unique perception of the World around him…

Ever since French physicist Louis de Broglie first described the wave-particle duality in 1926, scientists have struggled to come to terms with this strange particularity of our natural World when observed at the quantum level. Waves can be particles, and particles can be waves. But are entities waves AND particles all at the same time?

Since October 24, 2014, Alan Eustace holds the World Records for vertical speed reached during freefall with a peak velocity of 1,321 kilometres per hour (822 mph) and total freefall distance of 123,414 feet – lasting four minutes and 27 seconds.

The Leviathan is a large natural gas field located in the Eastern Mediterranean Sea. Together with the nearby Tamar gas field, the Leviathan has been seen as an opportunity for Israel to become a major energy power in the Middle East. This is the Leviathan – a giant gas field with the titanic potential to change Israel’s foreign relations towards a closer collaboration with Turkey and Egypt. Good news in an uncertain energy security climate…

Eggs Benedict! The perfect breakfast item. Probably. If both you and I love this indulgent breakfast staple, it’s down to that wonderful creamy and tangy garnish that is really the glue that holds the eggs benedict together. The perfect Hollandaise sauce…

It seems quiet at first, and even dull. Not much happening… Dreich, as one might say! Sad. Grim. Bleak. Not much to do… Not much to see here… Just sheep… But wait!! Look closer! Is that Dolly in this field? Now, that’s interesting! Oh, Aye, we’re in Scotland! It changes EVERYTHING…
