Little Tin Soldiers of Indonesia

Does exactly What It Says on the…

Tin – an important element for the electronics industry.  Tin is in high demand to manufacture devices like smartphones and tablets.  In Indonesia and elsewhere, people work in mines to dig tin ore out of the ground.  A dangerous job is made even more unsafe where the mine is being run illegally.  And it is not just the adults who take risks.  Children in Indonesia are working in brutal conditions to collect the materials used in our cool gadgets.  The manufacturers are complicit.  Do you really feel like buying that brand new mobile phone now?

We Need to Talk about Multiple Sclerosis…

A pictorial representation of what Multiple Sclerosis does to the mind and body.
Multiple Sclerosis?  Is that contagious?

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 wellThat 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…

Lightning and the Sun’s Magnetic Field

A photograph showing lightning over Glasgow's West End.
Magnetic Fields All Around

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…

Leviathan: The Energy Giant that Sleeps under the Mediterranean

The Leviathan Natural Gas Field

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…

Scotland’s Quiet Revolutions

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…

We Glimpse at the Body Electric – An Introduction to the Physics of the Human Nervous System

An artist's impression of the human nervous system at work.
The Human Nervous System: 100 Plus Billion Cells

The human nervous system contains roughly 100 billion nerve cells.  Worth pausing for an instant… and read it again.  That’s right, 100 billions!  To give an idea of the scale, the Milky Way, our own galaxy, contains roughly 100 billion stars.  And although human beings are way smaller than galaxies, we begin to appreciate how each one of us is as complex, as mysterious, and as magnificent in its own right, as any large astronomical entity in the physical Universe

Van der Waals and the Gecko

The Sticky Physics of Van der Waals Forces

Geckos are amazing creatures.  They scamper up walls, scuttle along ceilings and hang upside down on polished glass surfaces.  However, the secret of their amazing climbing ability remained a mystery until relatively recently.  The secret lies in weak intermolecular forces, described by Van der Waals in 1873.

Graphite to Graphene… in a Kitchen Blender

The Wonder Material

Ten years ago, the discovery of the wonder material – Graphene – was announced.  Graphene is thin, stronger than steel, flexible, non-metallic, yet electrically conductive.  For all these reasons, graphene promises to transform electronics, as well as other technologies.  Because of its potential in industry, researchers have been looking for ways to make defect-free graphene in large amounts.
