Will humans ever become cyborgs?

Blogging science to life

Tue 19 May 2015, Joel Sanderson

Joel from our Live Science Team explores whether humans have become cybernetic organisms...

The traditional view of a cyborg is a person that has been modified with electronic or mechanical features, which would usually require some kind of invasive surgical procedure. Perhaps an eye has been replaced with an infra-red camera, or the mind is half a computer that can understand any language on the planet.


Despite the possible advantages, if these modifications were widely available I still don’t think that most of us would be opting for them. Technology that requires invasive surgical procedures that might permanently alter our bodies is not, I imagine, appealing to the majority of people.  

However, I do think that most of us are cyborgs of a certain sort, we just don’t realise it.

Think about the kind of things that cyborgs can usually do in science fiction. Perhaps they can see in the dark or read people’s vital statistics, like a heart rate, just by looking at them. We don’t have circuits and wires running under our skin or through our skulls, but a lot of us do now have the ability to do previously unthinkable acts of science fiction via our smart phones.

Imagine that you can see in the dark. You could assess landscapes before you get to them and have a pre-planned route to a specific location. You could look through cloud to see the location of stars. You could tap into the collective consciousness of your species to find out the answer to almost any question you can think of, and talk to people who aren’t in front of you. Yet all of these things can be achieved through a smart phone with the appropriate application.

Phones can ‘look’ at people’s faces and, through detecting tiny variations in skin tone associated with blood flow, can monitor a heart rate. A smart phone can monitor your movements in bed and wake you up at an appropriate time during your sleep cycles so that you feel more refreshed. People can input the data from their gym sessions to allow applications to plan their progress in a given endeavour, pushing them to get better, faster and stronger.

So although we aren’t soldering each others eye sockets or having the latest titanium limbs fitted at the local ‘body’ shop, we are now living lives that are massively augmented. Through the external modules of technology that we call smart phones, I think we have already become cyborgs. Just not in the way that science fiction predicted.

Happy birthday Hubble!

Blogging science to life

Wed 29 April 2015, Will Davies (Live Science Team)

Last week marked the 25th anniversary of the launch of what might just be the coolest camera ever built, and certainly the coldest. Happy birthday to the Hubble Space Telescope, in the chilly reaches beyond our atmosphere. It’s been a source of amazing images of deep space for over two decades, and each sight is as breathtaking as the last. Let’s take a moment to reflect on this reflector, from a troubled start to years of wonder, and even glimpse at what the future holds. 

Hubble Space Telescope

Named after American astronomer Edwin Powell Hubble (1889–1953), the Hubble Space Telescope (HST) wasn’t the first of its kind. The prospect of space-based optics had been suggested as early as 1923, long before manned rocketry took off. It took constant pressure from Dr. Lyman Spitzer, who had written about the advantages observations from orbit would have over terrestrial telescopes, to start outlining a mission in 1965. 

Such things don’t come cheap and funding the mission faced hold-ups and outright cancellation. Promotion of astronomers, astronauts and a public campaign won back only half of their original budget. This meant a downsizing of Hubble’s primary mirror from 3 to 2.4m which, while still sizable, lowered the limit of how much light could be captured significantly. 

Grinding of Hubble's primary mirror at Perkin-Elmer, March 1979

After years of delays, rising costs and having to invent new equipment to build the equipment that HST would carry, a launch date was finally set for October 1986. Then, in the January of that year, the Challenger space shuttle suffered a catastrophic joint failure, causing the death of all seven astronauts aboard. The shuttle fleet was grounded, and all launches cancelled.

Eventually, after more than 20 years of design, redesign, cancellation and some $2.5 billion, on April 24th 1990 the STS-31 shuttle mission launched from Kennedy Space centre in Florida. Aboard it, at last, flew the The Hubble Space Telescope.

STS-31 shuttle launch

Which didn’t work. The mirror mentioned before is the most important part of a reflecting telescope, and having exactly the right curve to the mirror to focus all of its reflected light requires a carefully engineered correcting machine. Unfortunately the correcting machine was incorrectly assembled (even NASA suffers the astronomical equivalent of post-IKEA anxiety). This led to a focussing error on the mirror of one edge being misaligned by 0.00022cm, so a set of corrective lenses were installed. As imperceptiable as this sounds, it made a big difference. Just take a look at these before and after images:

Hubble image before and after correction 

So, by now you’re probably wondering if all the time and trouble was worth it. I mean, what does 25 years and $2.5bn get you? How about:

  • Set the estimated age of the universe at 13-14bn years
  • Found 3000 galaxies from the smallest, darkest corner of the night sky
  • Which altogether means about 500,000,000,000,000 galaxies in the universe
  • And that since the big bang, rather than slowing down, the universe appears to be accelerating outwards 
  • Identified that black holes make up the core of pretty much every galaxy
  • Recorded the collision of comet Shoemaker-Levy 9 with Jupiter

And it’s not even done exploring yet! Though at 25 years old HST is no spring chicken in terms of technology. Replacement or upgraded parts can only do so much to boost its observational ability. Which is why construction is already underway for a new generation, the James Webb Space Telescope (JWST). Not a direct successor JWST is more finely attuned to the oldest and furthest bodies in the universe. Until such a day as it’s called back home to Earth, HST will be up above with a careful eye watching, exploring and discovering.

Happy birthday Hubble! 

Coming soon... look out for our display of the Hubble Space Telescope 25th anniversary image in our foyer.

Alien Tours: an out-of-this-world view of At-Bristol

Blogging science to life

Sat 28 March 2015, Jennifer Garrett

We caught up with our robot tour guide to find out about Alien Tours, why aliens are here and what you can get up to...


Hello, nice to meet you! Could you introduce yourself?

Greetings human spawn of the Earth. I am Cybernetic Android Tour Enhancer, but you can call me CATE for short. May I complement you on your excellent appendages? Your thumbs are particularly wonderful... I’ve just downloaded a compliment function, it’s still settling in.

Oh... thank you! So what brings you to At-Bristol?

I was sent here as a virtual programme and have built myself out of Earth parts. I’m programmed to deliver tours and explain this quaint little planet, you locals call ‘Earth’. Life forms from all across the galaxy are welcome to join the tour to explore the wonders of hominid life.

Robot aliens

Are you enjoying life on Earth?

In order to appreciate Earth to the fullest, I have programmed myself using an Encyclopaedia. I found it in a skip along with my left eye and third thumb (it’s a spare just in case). I don’t why anyone would throw away a CD-ROM, terribly useful. Today I learned about ancient Egyptians, Echolocation and Encyclopaedias... I must confess I was confused up until that point.  

So how do these tours work?

I take intergalactic travellers around the exhibits and will guide you around the oddities of life on this planet, and explore the history and function of Earth. The wonderful thing about At-Bristol is there are lots of exhibitions that explain your world. While we’re on the tour we may even see some humans!

RoboChef, CATE and Alien

Can anyone come?

Anyone can pay two and a half earth pounds for full size intergalactic travellers and one pound fifty for younger space travellers. Currency exchange points can be found on the dark side of the moon.

To wrap up, here are 5 quick-fire questions:

  • Favourite hobby? Downloading human programmes. Today I learnt rhetorical questions, metaphors and high-fives.
  • Pet hate? I couldn’t possibly hate pets, from what I’ve learnt they’re meant to be adorable.
  • What do you miss most about your planet? Telekinesis, and the night life.
  • What do you do on your days off? Recharge, literally.
  • Best part of your job? It’s my life’s purpose.

Aliens have landed in At-Bristol, and you’re one of them! Our robot tour guide will take you around At-Bristol to explore the planet Earth and the humans who live there, all through the ‘eye’ of an alien! From 30 March to 12 April visitors will be able to dress up in alien costumes* and follow our expert robot tour guide around At-Bristol to learn about the bizarre species ‘humanity’.

* Cost: Adults £2.50, Children £1.50 (in addition to standard admission)

Fairtrade for Sustainability - The At-Bristol view

Blogging science to life

Thu 26 March 2015, Written by: Nicole

Here in At-Bristol Science Centre we’re lucky enough to be able supply and use Fairtrade goods in a variety of ways, whether in the catering choices we make in our café and events menus, in the shop products we sell or the procurement process for our hands-on science activities.

It’s part of our commitment to sustainable business practice which aims to limit the negative impact of our choices while educating and inspiring others.

These Fairtrade choices mean that as well as providing our visitors with higher standard products we’re also able to work with local Fairtrade suppliers and producers in various collaborative, innovative (and often tasty) ways!

Spring kitchen

One such project is one of our latest Spring Kitchen activities in our new Food! exhibition, using Divine chocolate as part of a chocolate tasting masterclass. As well as and kindly donating the chocolate Divine also lent us a chocolatier for the day during Fairtrade fortnight. David popped in to help our visitors and Live Science Team learn the journey from bean to bar and the important role the senses play ready for the launch of our Spring Kitchen - needless to say we had a number of willing volunteers!

These Meet the Expert sessions are important for us and our visitors, creating an important learning experience through interesting conversation and by getting hands-on. During the International Fairtrade Conference week (4-5 July 2015) we’re delighted to be welcoming Ghanian teenagers to our venue to talk to school groups about the life of a chocolate grower.

Our commitment to being a sustainable venue affects all our practices even down to the procurement of the wood for our events terrace, which is Fairtrade certified! Changes such as these have seen us winning the Best Fairtrade café gold award to the second year running and we also managed a gold award for our conferencing services.

Finally we continue to increase the number of Fairtrade products for you lovely lot to get your hands on in our shop. This Spring we’ll add herbal teas, chocolate spreads and herbs and spices to our range including delicious Shaun the sheep Easter eggs – so choosing Fairtrade has never been tastier!

We can’t wait to host and play a part in the International Fairtrade Conference 2015 – only 100 days to wait!
