Programme, Summer 2019

Reminder. Because of a clash with the May bank holiday, our first meeting of the summer will not be until June. It’s a pity, but there’s nothing we can do about it.

‘Eggs’

As it’s Easter time, I thought that I should post an article about eggs.  But what exactly?  There’s so much ‘biochemical’ information available, and so much discussion about the ovoid shape of eggs – and why it varies from species to species – that it’s difficult to chose.  So, instead, I’ve searched the internet for something closer to my own experience.  See if you can work out what the photo below shows – you’ll have to forgive me for classifying near-perfect spheres as ‘egg-shaped’.  (Apologies, I spent some time looking for a sharper photo, but this is the best that I could find.  In the past, I’ve seen fairly clear photos of ‘eggs’ apparently just about to emerge from a crack.)

If you don’t recognise what’s in the photo, and you’ve given up guessing, click on it to find out more…

Geothermal heat in the Midlands…

There’s a village in Worcestershire that I know quite well.  It’s Offenham, in the District of Wychavon.  The village has a riverside pub, thatched cottages and a maypole at the end of the cul-de-sac Main Street.  (And, yes, children from the local school do dance round it.)  But the village and surroundings are also heavily ‘industrialised’, with acres of glass houses.  At certain times of the year, some are brightly lit by sodium lights, with steam rising from their heating systems.  Market gardening can be an energy-intensive operation.

So, you can see the relevance of the article below, which I’ve taken from the local free magazine.

As it happens, I’ve been watching interest in geothermal energy wax and wane for decades.  Will this particular project be a success?  It might – all that’s needed is low-grade heat.

(I’ll say little about the washing machine-sized unit that’s also mentioned above;  there aren’t enough details…….  But I’ve found a smart website which seems to be relevant and which states: “Ricardo found HERU [the device discussed] had up to 733% less global warming potential than our current methods.”  733% – that makes you think.)

Blackbushe Airport, 1st April

Dennis Judd has very generously provided us with a complete set of his slides about Blackbushe Airport.  You can see them by clicking on the picture below.

One of the events that Dennis mentioned was the production of a black and white film.  David has sent some more information:

“Further to Dennis Judd’s talk last week I can provide information about the film he mentioned.  It was a 1954 film called “The Runaway Bus” and starred Frankie Howerd, Margaret Rutherford and Petula Clark.  The following link is to the IMDB movie database article –

This film might even get a showing on Talking Pictures TV (Freeview Channel 81) sometime in the future.”

Immune cells tackle a human obstacle course …

Roger has provided a link to a recent article about the movement of white blood cells through the body.  Intriguingly, it actually describes how cells move through man-made obstacle courses in the laboratory.  As always, click on the picture below.  Note, the video includes sound – don’t miss it!

Earth is drinking more seawater than previously thought….

Geology doesn’t appear very often in this blog.  But here’s an exception:

A new study suggests that the earth’s mantle is home to much more water than was previously believed.  You can read all about it by clicking on the photo below.  (Apologies, but the article is accompanied by lots of advertisements.  Just ignore them!)
