The British Skeleton Team – Sliding to Victory

skeleton olympic

How would you like to slide down a very steep and winding track of ice on something very similar to a tea tray at around 140km per hour? Yes, no, maybe. Well, there are people out there who can and do want to. And what’s more, they’re really rather good at it.
 Alongside Bobsleigh and Luge, the Skeleton is one of three sliding sports that take place on artificially refrigerated ice tracks. It’s a really white knuckle experience as each skeleton athlete pushes their sled one handed away from the start before lying down with their face first as they travel the track, using their shoulders, knees and toes for steering.

So You Want to be a … Diplomat?

When you think of a diplomat, what do you imagine? For some, it will be posh frocks and parties. Others will think of exciting spying missions in exotic countries – Our Man in Havana, or perhaps Our Woman in Harare? If you want to be a diplomat, we have some great advice for you today. This was written from the viewpoint of UK Foreign Office applicant, but much of this will apply to citizens of other countries too.

A Trip to Mars!

Imagine being able to catch a flight to Mars as easily as we travel to another country – that was the idea behind the Trip To Mars session I attended at the Cheltenham Science Festival. It was conducted by Dr Suze Kundu and Dr Simon Foster and presented as a pre-flight safety briefing, with both of them dressed as pilots! There were a lot of humorous moments and sci-fi references but also some great science.

Suze and Simon suggested that in the future, flights to Mars could be far quicker than they are now, and explored how some of the bigger problems could be overcome. For example, the Sun’s magnetic field deflects a significant proportion of the cosmic radiation that could be harmful to humans on Earth; as spaceships travel further away from the Earth and Sun they will have less protection because the magnetic field weakens. To combat this it’s possible that spaceships will contain or be covered with large and powerful magnets, to produce the same deflective effect. This would have the added advantage of also deflecting radiation from solar flares.

Spaceships journeying to Mars would travel at such speed that even tiny fragments of rock and dust could be damaging to the hull. To combat this, and also the heat generated when the spaceship passes through an atmosphere, Suze and Simon discussed the possibility of spaceships being coated in aerogel. This amazing material is a solid formed from silicone dioxide but is 98% air; this means that it is extremely light but also strong. Its melting point is 1,200°C (equivalent to asbestos) and it is a wonderful insulator. Because it consists of large pockets of air between thin layers of silicone dioxide, any dust or rock fragments that hit it would be slowed and stopped before they could penetrate the aerogel completely.

Suze and Simon also discussed the possibilities and problems with cryostasis. Theoretically this is when a person’s body is cooled to temperatures so low that they enter hibernation, ideal for long journeys through space. Unfortunately our technology isn’t advanced enough to do this at the moment; any attempt would result in the cells rupturing and the person dying. But in the future it will be possible, perhaps after the person’s DNA has been altered slightly so that they can produce antifreeze proteins like some species of wasps and turtles.

How to Negotiate a Later Bedtime

how to negotiate

Communication and negotiation are two ways of helping you get what you want, without fighting or arguing with your parents, family or friends or even at school with your teacher. If you communicate and negotiate well, you and the person you are negotiating with can come to a agreement without either of you feeling like you “gave in” or lost the argument.

Real Life Minecraft – Cactus

Part of our series on the features in Minecraft. If you are a Minecraft player, then you know that Cactus blocks grow naturally in deserts and mesas. The blocks can be harvested, but will destroy any items that come in contact with them. But what are REAL cacti like (and why do we sometimes say “cactus” and other times say “cacti”? Sarah takes a closer look.
