To be a scientist, you need a well-rounded education

Of late, science has demonstrated why all types of knowledge lead to discoveries.

Science has been demonstrating the value of a broad education. Let’s start with classics. If you’ve read your Herodotus you’ll know that Persian kings insisted on drinking water that was transported in silver containers because they would keep the water fresh. The water supplies on the International Space Station are fed through silver for exactly the same reason.

Now, nearly two and a half thousand years after Hippocrates described the healing properties of silver, we know how it works. A team at Boston University has shown that, when dissolved, silver ions will get inside the bacterium and send its oxygen-generating machinery into overdrive, making the bug self-destruct.

Clearly, dissolved silver ions have been doing a great job throughout history and we can now expect even more. The Boston team showed that silver ions will also lever open the membranes surrounding various microbes, allowing antibiotic medicines to penetrate the bug’s defences. A dose of silver seems to disable many bugs’ resistance to our drugs: there is now talk of the ancients’ antibiotic getting us out of the terrifying growth of antibiotic resistance.

It’s worth sounding a note of caution here. For years, proponents of alternative medicine have been pushing “colloidal silver”, a suspension of microscopic silver particles, as a treatment for everything from cancer to haemorrhoids. However, European regulators and the US Food and Drug Administration have banned any over-the-counter sales because in most scenarios the best it will do is turn your skin a purple-grey as the silver ions accumulate in your body.

As unsightly physical afflictions go, the effects of a silver overdose are right up there with the Black Death, which has also caught the attention of scientists – though this time it’s a history lesson. The bacterium that wiped out half of Europe’s population between 1347 and 1351 is still around. However, it doesn’t seem particularly deadly to modern scientific eyes, which makes the virulence somewhat puzzling. That puzzle is about to be solved: thanks to a newly developed technique, scientists are studying the genomes of the various strains of plague bacterium. The hope is that the insights gained will warn us about which subtle changes to pathogens in our environment could lead to widespread modern-day epidemics.

Thanks to the same new technique, we also now have the complete genome sequence of a leprosy bug carried by a young Danish woman who died 700 years ago. The makeup of the medieval bacterium, published in the 14 June issue of Sciencemagazine, is remarkably similar to what we know of the make-up of modern leprosy bacteria. That means the Danish leper may well help us find new treatments.

Finally, religious studies. The writer of Ecclesiastes said there’s nothing new under the sun, and the US National Institutes of Health has decided that it’s a good piece of advice. The NIH has instigated a programme which suggests that the best way of speeding the discovery of new drugs is to repurpose the old ones. Drugs that passed safety tests but were abandoned for reasons of efficacy or profitability are being tried in previously unexplored applications. So far, the search has unearthed candidates for treating conditions such as Alzheimer’s disease, alcohol and nicotine addiction and muscular dystrophy. The drugs will now go into animal studies and clinical trials; researchers hope that some will reach the market in a few years’ time.

Stability is essential to solve the pension problem

The new chancellor must ensure we have a period of stability for pension policymaking in order for everyone to acclimatise to a new era of personal responsibility in retirement, says 

There was a time when retirement seemed to take care of itself. It was normal to work, retire and then receive the state pension plus a company final salary pension, often a fairly generous figure, which also paid out to a spouse or partner on death.

That normality simply doesn’t exist for most people in 2016. There is much less certainty on what retirement looks like. The genesis of these experiences also starts much earlier. As final salary schemes fall out of favour, the UK is reaching a tipping point where savings in ‘defined contribution’ pension schemes become the most prevalent form of traditional retirement saving.

Saving for a ‘pension’ can mean a multitude of different things and the way your savings are organised can make a big difference to whether or not you are able to do what you planned in your later life – and also how your money is treated once you die.

George Osborne established a place for himself in the canon of personal savings policy through the introduction of ‘freedom and choice’ in pensions in 2015. This changed the rules dramatically, and gave pension income a level of public interest it had never seen before. Effectively the policymakers changed the rules, left the ring and took the ropes with them as we entered a new era of personal responsibility in retirement.

But what difference has that made? Have people changed their plans as a result, and what does 'normal' for retirement income look like now?

Old Mutual Wealth has just released. with YouGov, its third detailed survey of how people in the UK are planning their income needs in retirement. What is becoming clear is that 'normal' looks nothing like it did before. People have adjusted and are operating according to a new normal.

In the new normal, people are reliant on multiple sources of income in retirement, including actively using their home, as more people anticipate downsizing to provide some income. 24 per cent of future retirees have said they would consider releasing value from their home in one way or another.

In the new normal, working beyond your state pension age is no longer seen as drudgery. With increasing longevity, the appeal of keeping busy with work has grown. Almost one-third of future retirees are expecting work to provide some of their income in retirement, with just under half suggesting one of the reasons for doing so would be to maintain social interaction.

The new normal means less binary decision-making. Each choice an individual makes along the way becomes critical, and the answers themselves are less obvious. How do you best invest your savings? Where is the best place for a rainy day fund? How do you want to take income in the future and what happens to your assets when you die?

 An abundance of choices to provide answers to the above questions is good, but too much choice can paralyse decision-making. The new normal requires a plan earlier in life.

All the while, policymakers have continued to give people plenty of things to think about. In the past 12 months alone, the previous chancellor deliberated over whether – and how – to cut pension tax relief for higher earners. The ‘pensions-ISA’ system was mooted as the culmination of a project to hand savers complete control over their retirement savings, while also providing a welcome boost to Treasury coffers in the short term.

During her time as pensions minister, Baroness Altmann voiced her support for the current system of taxing pension income, rather than contributions, indicating a split between the DWP and HM Treasury on the matter. Baroness Altmann’s replacement at the DWP is Richard Harrington. It remains to be seen how much influence he will have and on what side of the camp he sits regarding taxing pensions.

Meanwhile, Philip Hammond has entered the Treasury while our new Prime Minister calls for greater unity. Following a tumultuous time for pensions, a change in tone towards greater unity and cross-department collaboration would be very welcome.

In order for everyone to acclimatise properly to the new normal, the new chancellor should commit to a return to a longer-term, strategic approach to pensions policymaking, enabling all parties, from regulators and providers to customers, to make decisions with confidence that the landscape will not continue to shift as fundamentally as it has in recent times.
