Bacterial ‘gardening’ to solve antibiotic resistance?

Steve Pointing Jan 08, 2015

Reckless over-use of antibiotics in livestock and humans is creating a healthcare time bomb where some super-bacteria are resistant to conventional antibiotic treatments.  The magnitude of this problem has been recognised by the several governments (see my earlier blog on this: http://pointingatscience.blogspot.co.nz/2014/06/longitude-prize-to-focus-on-antibiotic.html).  This problem is also exacerbated by the fact that few truly novel antibiotics have been introduced in … Read More

Pussyfooting around land mines may help leopard conservation

Steve Pointing Jan 02, 2015

An intriguing conservation story has emerged in recent weeks from the mountainous region of Kurdistan on the Iran/Iraq border.  This area was disputed during the Iran/Iraq War of the 1980’s and was heavily populated with land mines.  These are an evil and indiscriminate weapon with a legacy that affects civilian populations long after any conflict has ceased.  In Kurdistan however, at … Read More

Astrobiology takes centre stage

Steve Pointing Dec 12, 2014

Astrobiologists are all a flutter today as the Rosetta team announced their first detailed scientific analysis of the comet Philae (http://sci.esa.int/rosetta/).  Their analysis of water isotopes showed that the composition varied significantly from those found in water on our planet today – and this debunks a popular theory in astrobiology that comets were the source of water on … Read More

Interstellar – real science in the movie?

Steve Pointing Nov 12, 2014

The latest Christopher Nolan extravaganza “Interstellar” hit our screens this week – a science fiction epic that begins with the premise that mankind has messed up earth to the extent we need to find a new planet to live on or face extinction. The trailer opens with a world ravaged by massive dust storms that are symptomatic of failing agriculture … Read More

Rosetta makes history

Steve Pointing Nov 12, 2014

Momentous history was achieved in space today - Rosetta's probe Philae successfully touched down on the surface of a comet after a chase of more than 6 billion km.  The probe will attempt to characterise the surface and subsurface of the comet, and may start to answer some of the most fundamental questions about how life began on earth - … Read More

Hooray – it’s World Science Day!

Steve Pointing Nov 09, 2014

Today is World Science Day, I know this because the UNESCO website tells me so.  Unfortunately I am not sure this is going to be high on the radar of many media outlets, or indeed for many science professionals.  This is a shame because it is... Read More
