Happy Autumn Day!!

Today, Wednesday 23rd September marks the official start of the marvellous orange and brown tinged season of Autumn. It is my favourite time of year, the nights get longer, the temperature starts to drop and the fallen leaves get oh so crisp and crunchy under foot. I basically LOVE Autumn. Anyway here's a quick recap of some of my favourite bits of science from this year (Jan-Sept).

January
The desert tawny owl became a new owl species on 25th January.The owl is of a medium size, which tends to be found around The Middle East, namely Syria, Israel and Egypt. The desert tawny owl feasts upon large insects and rodents.

February
The British Government voted in favour of 3-person babies in a bid to try and combat inherited mitochondrial disorders. This ruling is yet to be passed by the House of Lords, but if it is, then the UK will become the first country in the world to offer this form of prevention of mitochondrial disorders

March
On the 20th March a total solar eclipse occurred over most of Europe. A solar eclipse is when the moon moves infront of the sun, blocking the light of the sun; creating temporary darkness. This particular eclipse lasted for just over 1 minute when it began at 8.30 am GMT. (I actually missed this because I was in the lab!)

April
The Large Hadron Collidor returns to action after a stint of maintenance and an upgrading.

May
Nivolumab, a drug which is a monoclonal antibody (mAb) was approved for treatment of lung cancer and was shown to double life expectancy in some patients.

June
A 3D printed titanium jaw was implanted successfully into a male patient in Melbourne, Australia. Who knows what will be next? This is marvellous news, for patients who require uniquely designed implants to help rebuild body parts. A step forward in the right direction!

July
Stephen Hawking launches Breakthrough Initiatives, a program founded with the main intention to look for extraterrestrial intelligent life.

August
2 new venomous frog species were discovered in Brazil: Greening's frog and Bruno's casque-headed frog. Both species of frog have spines on their heads. By headbutting their victim they are able to inject poison.

September
WWF and ZSL found that populations of marine creatures, such as birds, fish, reptiles and mammals have declined around 47% since 1970.


Hopefully the next 3 months of 2015 will be just as spectacular in the world of science!

Are you AI-live?

We know all about robots and the obsession we seem to have with creating something in as much of a life-like way as possible. The awe which we hold when robots carry-out complex tasks which we label as being 'human'.

ASIMO, Honda's robot.
Even TV shows are appearing with the idea of AIs overtaking humans (my whole reason behind this post, is because I have started watching a drama series on AIs), not in number, but ability and intelligence. Obviously, this is a figment of someone's imagination on what the future holds, however, is the rise of the AI as fictitious as I would like to believe?

A couple of months ago a New York robot passed a test which is known as the King's Wise Men puzzle. This puzzle acts a method for detecting self-awareness. The test was adapted for 3 robots. The robots were told that they had been given a dumbing pill that prevented them from talking. They were then asked which of them could talk.

Initially all the robot's claimed not to know the answer to the puzzle until a single robot piped up after hearing its own voice and said 'Sorry, I know now!'

This is only the first step in achieving consciousness in a man-made being, however, actual self-awareness and the idea of robots with a 'conscience' is a way into the future.

What do you think about the possibility of a being so technically advanced that we would be unable to fix it or even compete with it on the basis of intelligence?


I have mixed feelings. It's great for the advancement of the fields of robotics, engineering and technology but what I would really like to know is where the line gets drawn between 
what is classified as living and not.


I will continue watching my AI drama series and live tweeting later today on Twitter: @TheScienceTree

En route for Collision!

I don't know whether it was because I was watching Angels and Demons this morning, that I suddenly thought what was happening with the LHC (Large Hadron Collider). Having not heard anything about it since they switched it on in 2008/2009, and apart from the Higgs Boson particle discovery,  I thought it was time to find out what was happening in regards to this pretty awesome piece of scientific kit.

The background
The Large Hadron Collider is a particle accelerator. It is comprised of superconducting magnets along its 27 km circumference. The role of the magnets is to boost the energy of the particles moving inside the accelerator. Two high energy particle beams are put into the accelerator, in different pipes; where they move almost at the speed of light. As the beams whizz around, another magnet is used to push them closer together to increase the likelihood of a collision. If and when the particles collide, the energy released is received via 4 particle detectors.

Currently...
The LHC has been switched off which allows the engineers and technicians to carry out maintenance on the $9bn machinery. Although there is no current time frame for when the collider will be up and running again, it is very important that the work is carried out properly for 3 reasons: to ensure more positive results for physics; a machine working to its full potential and above all safety of  those who work alongside it. Ensuring these constraints are met, means no rushing to finish the repairs by a specific date.

I understand that a thorough maintenance of the LHC is what truly matters, and is potentially the gateway to exciting new discoveries in physics.
