Surrounding the town of El Ejido, Almeria Province, southern Spain is a sea of greenhouses, stretching for tens of kilometres, visible from space. Millions of tons of vegetables are exported from there to other European countries and further parts of the World. Along the Mediterranean coast, tourism flourishes, fuelling a booming real estate economy…
Should you ever have wondered what the Higgs boson sounds like… It’s… “AS LOUD AS A RIFF BY JOE SATRIANI. WHAT?! IT’S AS LOUD… AS A…” Oh, wait!! Here it is.

“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…
