If scientists wrote horoscopes, this is what yours would say

Martha Gill's Irrational Animals column.

A new year, a new set of horoscopes, a renewed chorus from naysayers who fail to see the link between when they were born and what will happen to them next Tuesday. But science says they’re just not looking hard enough. Tiny seasonal variations at your time of birth can affect both your health and your character. Finally - here’s a horoscope based on real medical evidence.

Aries: 21 March – 19 April
You’ve never been that bright, Aries, and medics at Indiana University put this down to a heightened use of pesticides around the time of your birth. You also sometimes feel that you’re sleepwalking through life. Give in to the feeling - it’s just narcolepsy (more likely in those born in March or April).

Taurus: 20 April – 20 May
Oh, Taurus, sometimes you’re on top of the world, other times you just can’t get out of bed. Your friends are confused: what’s going on? Tell them that babies born in May are happier – they first experienced the world in summer. They are also more likely to suffer from seasonal affective disorder; depression hits in the darker months.

Gemini: 21 May – 21 June
Children born at this time are often better behaved and less likely to play truant. Maybe it’s time to let loose a bit, Gemini.

Cancer: 22 June – 22 July
Cancerians, you usually think yourselves lucky – due to low rates of postnatal depression in mothers of summer babies. Your instincts are off, however: you’re at a slightly higher risk of Hodgkin’s lymphoma, according to Danish research from 2003.

Leo: 23 July – 22 August
Your friends tell you you’re just not the maternal type. They’re right: Austrian research finds that those born now grow up to have the fewest children.

Virgo: 23 August – 22 September
You keep telling people you’re big-boned but they don’t believe you. It’s true, though – your mother got more sunlight as her pregnancy progressed and the Vitamin D gave you thick, strong bones. See?

Libra: 23 September – 22 October
Librans, you have the best chance of becoming a professional footballer. You’ll be one of the biggest children in the school year and get picked for the best team early on. Things will progress from there. Hurray for Jupiter in the ascendant or whatever.

Scorpio: 23 October – 21 November
This year is as good a time as any to take up yoga, because you’ll be feeling flexible and energetic, partly because of your low risk of arthritis and multiple sclerosis (as your mother got plenty of sunlight late in her pregnancy).

Sagittarius: 22 November – 21 December
Sagittarians like to live life at the sharp end – December babies are the most likely to become dentists. But take off those plastic gloves and have a rest in the chair: cold temperatures at birth increased your risk of eczema and heart disease.

Capricorn: 22 December – 19 January
Capricornians, you are clever, tall and successful – your mother was pregnant in the summer and ate lots of fruit and vegetables. If you have one flaw, it’s that irritating tendency to have epilepsy, caused by prenatal winter infections.

Aquarius: 20 January – 18 February
This year, you’ll be as clearsighted as ever; low levels of daylight at birth gave you better long-distance vision. Older Aquarians may be feeling under the weather, though – an early lack of Vitamin D has been linked to depression later in life.

Pisces: 19 February – 20 March
Assertive, successful, bossy: there are more CEOs born now than at any other time of the year. Male Pisceans beware: you’re at a marginally higher risk of autism.

How Jim Murphy's mistake cost Labour - and helped make Ruth Davidson

Scottish Labour's former leader's great mistake was to run away from Labour's Scottish referendum, not on it.

The strange revival of Conservative Scotland? Another poll from north of the border, this time from the Times and YouGov, shows the Tories experiencing a revival in Scotland, up to 28 per cent of the vote, enough to net seven extra seats from the SNP.

Adding to the Nationalists’ misery, according to the same poll, they would lose East Dunbartonshire to the Liberal Democrats, reducing their strength in the Commons to a still-formidable 47 seats.

It could be worse than the polls suggest, however. In the elections to the Scottish Parliament last year, parties which backed a No vote in the referendum did better in the first-past-the-post seats than the polls would have suggested – thanks to tactical voting by No voters, who backed whichever party had the best chance of beating the SNP.

The strategic insight of Ruth Davidson, the Conservative leader in Scotland, was to to recast her party as the loudest defender of the Union between Scotland and the rest of the United Kingdom. She has absorbed large chunks of that vote from the Liberal Democrats and Labour, but, paradoxically, at the Holyrood elections at least, the “Unionist coalition” she assembled helped those parties even though it cost the vote share.

The big thing to watch is not just where the parties of the Union make gains, but where they successfully form strong second-places against whoever the strongest pro-Union party is.

Davidson’s popularity and eye for a good photo opportunity – which came first is an interesting question – mean that the natural benefactor in most places will likely be the Tories.

But it could have been very different. The first politician to hit successfully upon the “last defender of the Union” routine was Ian Murray, the last Labour MP in Scotland, who squeezed both the  Liberal Democrat and Conservative vote in his seat of Edinburgh South.

His then-leader in Scotland, Jim Murphy, had a different idea. He fought the election in 2015 to the SNP’s left, with the slogan of “Whether you’re Yes, or No, the Tories have got to go”.  There were a couple of problems with that approach, as one  former staffer put it: “Firstly, the SNP weren’t going to put the Tories in, and everyone knew it. Secondly, no-one but us wanted to move on [from the referendum]”.

Then again under different leadership, this time under Kezia Dugdale, Scottish Labour once again fought a campaign explicitly to the left of the SNP, promising to increase taxation to blunt cuts devolved from Westminster, and an agnostic position on the referendum. Dugdale said she’d be open to voting to leave the United Kingdom if Britain left the European Union. Senior Scottish Labour figures flirted with the idea that the party might be neutral in a forthcoming election. Once again, the party tried to move on – but no-one else wanted to move on.

How different things might be if instead of running away from their referendum campaign, Jim Murphy had run towards it in 2015.
