Saving Hope… – Cetacean Strandings and Satellites

A composite drawing image of Hope the Blue Whale's skeleton swimming between two waters.  Artwork: NaturPhilosophieIt’s unclear why so many great whales beach en masse around the World.  And it’s really difficult to estimate their number, especially when the cetacean strandings occur along remote shores.  But there is hope.  Scientists are now developing techniques to monitor marine populations from space.

The Universe Expands Far Faster Than Anticipated…

The Universe is accelerating

For a while now, astrophysicists have known that our Universe is expanding, and accelerating.  And much like the surface of a rubber balloon getting inflated, space is getting bigger, and bigger, and bigger… Continue reading The Universe Expands Far Faster Than Anticipated…

On 19 June 2018, a peculiar number emerged from the blockchain space.  The series of numbers and letters sent the cryptosphere into overdrive, sparking rampant talk of quantum computing breakthroughs, time travel, Satoshi’s return, and the esoteric meaning of Bitcoin.  Continue reading Time Travel or Quantum Leap – Where Does Bitcoin Meet Relativity?

Future Floods and Melting Ice Sheets – Predicting with GRACE

On the whole, Earth scientists agree that melting of land ice greatly contributes to sea-level rise.  And one thing’s for sure.  Future global warming will exacerbate the risks posed to human civilisation.  But…  What if you could forecast major floods?  You can.  Continue reading Future Floods and Melting Ice Sheets – Predicting with GRACE

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

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.  Continue reading A Theory of Life… The Physics of Cells and Macroscopic Irreversibility

The Discovery of Gravitational Waves – Merging Black Holes and Advanced LIGO

An animation illustrating two colliding and merging black holes in outer space.

Black Holes Far Ago Have Been Causing a Stir…

You know how when you throw a rock into a pool, that makes ripples in the water?  And how Einstein once upon a time predicted that the very mass of stars and planets should warp spacetime?  Although we have had a justified inkling that Einstein was right for quite some time, we had never before detected such a phenomenon.  Until THIS happened… Continue reading The Discovery of Gravitational Waves – Merging Black Holes and Advanced LIGO

Name: Tim Peake Job: Space Electrician

A selfie photograph taken by British astronaut Major Tim Peake of himself during his historic first space walk outside the International Space Station on 15 January 2016. The British Union flag is visible on the left shoulder of his pressure suit, as well as a view of the Earth being reflected in his visor. Spaceman, I always wanted you to go into space, man!

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.

We Check the Time of Death with Post-Mortem Degradation of Skeletal Proteins – And Other Gruesome Forensic Facts of Life

A photomontage showing a body outline, "Do Not Cross" yellow police tape, and a magnifier focused on the word "Forensics". The picture also lists the following forensic ways to estimate the time of death - Wait: Determine the time of death; Rigor mortis; Decomposition; Forensic Entomology; Succession on corpses; Other decomposers.Estimating the Time of Death

Forensic researchers from the University of Salzburg have developed a new method for establishing an exact time of death after as long as 10 days – a significant step forward from the current method of measuring core body temperature, which only works up to 36 hours after death.

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?

Space-Age Rocket

A photomontage showing the American space shuttle taking off over a background of roquette salad, hence "Space-Age Rocket".Salad Growing… in Space?

Ever since the early days of human space travel, back in the 1960s, astronauts have run experiments involving plants in space.  Over a million seeds of rocket (two kilograms of rocket seeds) are shortly due to take off from Florida, bound for the International Space Station, as part of British ESA astronaut Tim Peake’s six-month Principia mission.
