Galway nuked, radiation fireball blasts Athlone :(

The other day, a live World War II hand grenade was found in a garden just down the street from my house. Thirty families were evacuated from their homes in the middle of the night while the army bomb disposal unit came along to do their stuff. This is very unusual around where I live. For one thing, Ireland wasn’t in World War II, so how there came to be leftover weaponry lying around is something of a mystery. Nonetheless, for those who could have been affected, it’s a little scary to think that a live hand grenade could have detonated in a suburban housing estate.

By coincidence, today I came across this website, which enables you to simulate a bomb explosion in any part of the world. And not just any old bomb explosion, but a nuclear bomb explosion. All you need to do is point the little red arrow somewhere on Google Maps, select your kiloton yield, and — as might be expected from a website-based apocalypse dashboard — click on a button marked ’Detonate‘. And there you go. The software returns an image showing the blast radius in various concentric degrees of severity.

So I did what any red-blooded man in my position would do. I plonked the target right down on top of my own house, selected the biggest bomb available (the pimped-up 100-Mt version of the USSR’s Tsar Bomba), panned back so that I could see the full fallout, and then Continue reading

Headline-spectrum of the day: Dino-apocalypse by ‘wind’

So apparently, the dinosaurs are extinct. That’s not really news of course (time to let it go, Nessie fans). But what is making the news is some new research about how those terrible lizards ended up shuffling off this mortal coil en masse.

There is quite good geological evidence that some kind of massive catastrophic event occurred around 65 million years ago, pretty much around about the same time that dinosaurs stopped appearing in the fossil record. Most kids today will tell you that this was caused by a large asteroid (a theory known as the Alvarez impact hypothesis), but some scientists argue with these kids and believe instead that those geological remnants are not inconsistent with multiple asteroidal impacts, or perhaps with the world’s biggest volcano going ‘pop’ (or something).

A dinosaur earlier this year. Obviously.

But today we saw reports offering an alternative theory. Continue reading

Is there actually evidence for anti-ageing creams?

Here is a short piece I wrote for Tuesday’s Irish Independent. It was part of their ‘Science For Life’ supplement (not available online), in which scientists provide answers to “some of life’s big questions“. I was asked to respond to a question raised by current affairs broadcaster Miriam O’Callaghan (@miriamocal), who asked “Is there any scientific evidence that anti-ageing creams work?“ Naturally, given my own wrinkle-free visage (as featured prominently in the awesome and not-at-all embarrassing photograph that accompanied the piece), I was quickly identified as a suitable expert for this type of thing.  

The version below is the final draft prior to typographical edits. The Irish Independent’s ‘Science For Life’ section is edited by Katherine Donnelly, and its production is assisted by support from the Higher Education Authority and Dublin City of Science 2012, hosts of ESOF 2012.

IS THERE ANY SCIENTIFIC EVIDENCE THAT ANTI-AGEING CREAMS WORK?

This question divides scientific opinion. On the one hand, we know lots about the science of cell ageing, and many studies show how certain substances alter the skin’s appearance. However, lots of scientists are sceptical as to whether these substances can be made into a workable anti-ageing cream. And there is a dearth of scientific research showing that commercially available creams actually make a real difference. Continue reading

Once more, with feeling: ‘Weather’ is NOT ‘climate’

What is it with some media outlets and their tendency to gloss over the difference between ‘weather‘ and ‘climate‘? Let me give you the basics. Here’s the Wikipedia* explanation of the term ‘weather‘:

…the state of the atmosphere, to the degree that it is hot or cold, wet or dry, calm or stormy, clear or cloudy.

And here’s the one for ‘climate‘:

…the statistics of temperature, humidity, atmospheric pressure, wind, precipitation, atmospheric particle count and other meteorological elemental measurements in a given region over long periods. Climate can be contrasted to weather, which is the present condition of these elements and their variations over shorter periods. 

[*Those with a morbid mistrust of Wikipedia can consult the corresponding Oxford English Dictionary definitions here and here. (Hint: weather = '...at a particular place and time'; climate = '...over a long period'. You know. The same as in Wikipedia.)]

Weather is that short-term burst of meteorological whatchamacallit that just happens to be occurring right now, perhaps as the result of — hey, I don’t know — a “ridge of low pressure” or something. Like, today it happens to be rainy and cold. That’s weather.

Climate, on the other hand, is Continue reading
