In Brief: The House That Science Built

In Peter Hyams’s film “2010”, it seems the science fiction fanatics were a little optimistic about what kind of futuristic abode we might be living in today. The fact is, most houses in the UK are pre-1960 boxes, built at a time when “green” and “sustainable” weren’t a necessary part of a politician’s vocabulary. We are now rightly concerned about the choices which impact our energy consumption, and how those choices are concerned with a sustainable lifestyle, and (let’s face it) a cheaper utility bill!
Last week, Salford University hosted the first conference to discuss how to sustainably retrofit existing housing stock in the UK. It was also their chance to unveil the “Energy Hub” – a fully functional “Coronation street-style” terrace house, kitted out with all the appliances and mod-cons of an average 21st century home. The only unusual thing about this house is that it’s built inside a laboratory. The purpose of this project is to determine where old-buildings are losing the most energy, and try and come up with cost effective ways to reduce this loss. The lab is complete with internal weather simulation such as rain – which apparently alters the heat conductivity of the bricks – and a plethora of thermometers and gadgets to calculate energy wastage to the kilowatt. Soon, they hope to find inhabitants for the property, so they can monitor energy wastage as realistically as possible.
Speaking from recent memory of drafty, damp, student housing, I think this project has some promise. Understanding simple solutions that can be adopted by the average green conscious Joe is more likely to bring immediate benefits than the next gadget of the future. As of yet no data has been released, but perhaps we’ll start to notice a few savvy changes in Corries own Rovers pub over the next few months, “sustainable scratchings anyone?” Read the rest of this entry »

In Brief: Silly Walks, Work!

Andy Ruina an engineer from Cornell Univeristy, and Mario Gomez a mechanical engineer from Rochester Institute of Technology, have allegedly determined the mathematically most energy efficient technique of walking yet to be discovered – and I think it’s fair to say, it looks rather ridiculous (see video: Simulated on a simplified two-dimensional torso with rigid legs, the motion relies on a pendulum movement from the limbs, rocked back and forth by a springy torso. The key is, apparently, that each foot bears no weight until stationary on the floor. Published this month in Physical Review E, it is hoped this research might revolutionise robotics, whose state-of-art walkers currently require large amounts of energy to function, and generally in the overall understanding of human and animal locomotion. It also provides hopes for those in need of prosthetic limbs. Steve Collins, a mechanical engineer responsible for prosthetic limb research, believes though it is obviously not practical in its current state, the ideas could be reincorporated into revolutionary designs.

It is obviously still in its early stages of development and more detail needs to be added to the model before the true scope of applications can be realised, but I imagine the “Ministry of Silly Walks” will be happy to provide the funding

In Brief: Sexy Science

Today the BBC website was running a link to a face perception test, developed by the psychologist Prof. David Perret from St. Andrew’s University. The research was designed to determine whether your self perception as an introvert (quiet and happy to be left alone) or an extrovert (sociable, talkative and enjoy group activities) influenced your attraction to potential partners. First, you were asked to answer a short questionnaire regarding your own personality traits, and then rate twenty pairs of faces based on personal attractiveness. The hypothesis was that introverts would be attracted to faces showing less expression, and vice versa for extroverts. Prof. Perret believes behaviours such as these are important in partner choice. I apparently rated myself as an introvert (though I’m not sure I’d agree) – and who did I find the most attractive? … the extroverts. “Sorry Prof! I’ll be the anomaly in your dataset”. However, looking at the audience’s results it seems most people are attracted to the extroverts, and I’m not surprised, why would you choose the glum, uninterested looking face over the smiley cheeky chappy? Not quite convinced by this science, but it was some good procrastination.

See my results below, and to take the test yourself just click here:

Cell by Date

By Tiffany Taylor

It has recently been reported that one in six people in the UK today will live to see their 100th birthday. Interestingly, there was quite a loud outcry from the public who voiced their fears over reaching such a grand old age, but what do we really understand about ageing? In this article I will look at ageing from the genetic, cellular and multicellular level to find out what we know, what we don’t, and whether there’s anything we can do about it.
