Nanofibres can ease the pain of Parkinson’s disease (Day 331)

In the UK this week, it is Parkinson’s Awareness Week. The aim is to raise awareness of the disease by doing a good deed and tweeting about it using #upyourfriendly.

We can all get involved; just by being nice to the people we meet. You can make new friends and maybe someone’s life a little easier without even knowing it. Check out the campaign to learn more.

With this strategy in mind, I thought I’d raise awareness of the work of some chemical engineers who are definitely ‘up-ing their friendly’ by working behind the scenes to help combat the symptoms of this debilitating disease.

Researchers at Rice University in Texas, US, have developed flexible carbon nanotube fibres, that may provide an effective way of communicating directly with the brain.

Parkinson’s disease affects one in every 500 people. That’s an estimated 127,000 people in the UK – or around 8.5 million globally.

It is a progressive neurological condition that affects nerve cells in the brain, causing them to die. This results in lower dopamine levels in the body with serious implications for mobility and emotional behaviour.

Supercomputing our energy (Day 261)

LaptopsHigh specification personal computers mean that most of us can perform our jobs sat at home, work or even on the road.

But processing and modelling large amounts of data to help our understanding of complex and mammoth tasks like the formation of the universe, predicting weather patterns, or large and complex engineering problems require more than the average desktop computer.

Hence, the growth of supercomputers in recent times. But they don’t come cheap.

Later this year the UK’s Met Office £97 million (US$ 146 million) supercomputer will come online.

Eventually, its processing power will be 16 petaflops – meaning it can perform 16 quadrillion calculations every second.

The “Cray XC40” machine will have 480,000 central processing units or CPUs, which is 12 times as many as the current Met Office supercomputer, made by IBM.

At 140 tonnes, it will also be three times heavier – more a ‘floortop’ than a desktop.

Stirring stuff (Day 9)

CellsAn international collaboration of researchers in Germany, Netherlands and the US have used chemical engineering principles to track single molecules inside living cells with carbon nanotubes.

Chemical engineers from Rice University and biophysicists from Georg-August Universität Göttingen and VU University Amsterdam found that cells stir their interiors using the same motor proteins that serve in muscle contraction. The study, which sheds new light on biological transport mechanisms in cells, was published in Science.
