Sailing the Lower Midnight… – The Uncharted Frontier of Modern Deep Sea Exploration

Deep Sea Exploration: A photograph of the not-so-friendly, and frankly scary-looking, footballfish, a deep sea-predator from the anglerfish family.
What lies 5,000 metres below the sea?

It’s cold down there.  Icy cold.  It’s dark.  Pitch black, in fact.  And the crushing pressures make the deepest parts of the oceans into some of the most hostile places on our planet.

Global Winds and The Coriolis Effect – The Ever Changing Atmospheric System

A photograph showing blue sky and the wind blowing through a field of oats.
What is Wind?

It comes at you as a breeze.  As a gust.  As a gale.  Or in the scariest of situations as a hurricane or a tornado with wind speeds of up to 400 kilometres an hour.  But what is wind?

Looking on the Bright Side of Clinical Depression

A photograph showing a young man sitting alone near a beach, looking very down-hearted.

New Hope

A revolution in the treatment and understanding of clinical depression may be looming.  And specialists are already talking about one of the strongest discoveries in psychiatry for the past two decades.  For the 350 million people who suffer from the illness worldwide, this could potentially mean light at the end of the proverbial tunnel.

What is Your Poison of Choice?

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…

Ouch!! #$@*!! – We Take a Quick Look at the Neuro-Physics of Pain

A cartoon illustrating the phenomenon of physiological pain.
Signals and Perception

Prior to the discovery of nociceptors in 1906, scientists believed that animals were like mechanical devices that transformed the energy of sensory stimuli into motor responses.  Pain is one of those stimulated reactions, but it is unlike other sensations.  What is the purpose of pain?

We Consider Human Network Physiology and Medicine – The “Body Electric” – Part Deux

An illustration symbolising network physiology in medecine and the human organism integrated network, as a complex network with the Vitruvian man at its centre. The caption reads: "The human organism is an integrated network where complex physiological systems, each with its own regulatory mechanisms, continuously interact, and where failure of one system can trigger a breakdown of the entire network. A new field, Network Physiology, is needed to probe the network of interactions among diverse physiologic systems."

The Network Within Us

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.

In the Midst of the Sixth Mass Extinction…

An artist's impression of a post-apocalyptic New York City skyline, with the scorched cracked earth at the forefront and an eerie yellow glow at the background.
Exponential Population Growth

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?

A Theory of Life… The Physics of Cells and Macroscopic Irreversibility

A meme that reads: "Life has No Ctrl + Z".
“It’s Life!  But Not as We Know it…”

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.

Between the Lines of the Herculaneum Papyri using X-Ray Imaging Techniques

Scrolling Back the Past at Herculaneum

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?

A Day in the Life of a Plant – Photosynthesis and Phytochemistry

A photograph showing two hands together holding a clod of earth with a small green seedling.
Plant Life

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…
