Swedes prove Rudolph’s nose is really red

Swedish researchers at Lund University have confirmed once and for all the Rudolph the red nose reindeer lives up to his name after studying the behaviour of reindeer using high-tech equipment.

It's a story which has always puzzled children. Is Rudolph's nose really red or just a line in a song? Step forward Ronald Kröger, a professor of functional zoology at the University of Lund in southern Sweden who has solved the mystery.

"Reindeer live in a cold climate… and they are looking for food under the snow. When they are feeding their mule (nose) they are exposed to a very low temperature and have to prevent them from freezing.

"They have to know what they are eating and they do that by pumping warm blood into the mule and that means that it can be a bit reddish because of this strong blood flow in the lips and nose," Kröger said in an official Lund University video.

The researchers made the discovery by monitoring reindeer at the zoo of Nordic animals in Skåne throughout the night using a high-tech infrared camera which can detect heat sources that radiate off the body.

It became apparent to Kröger and his team after viewing the footage that not only do reindeer have warm eyes but also a glowing red nose.

He admitted that the motivation to conduct the study was inspired by his dog's wet nose.

"He touched my hand and I was getting curious as to why it was cold which is the opposite of the reindeer. Nobody really knows why it's cold and that is what we want to find out."

Is Switzerland’s male-only mandatory military service ‘discriminatory’?

Under Swiss law, all men must serve at least one year in compulsory national service. But is this discriminatory?

All men aged between the ages of 18 and 30 are required to complete compulsory military service in Switzerland. 

A lawsuit which worked its way through the Swiss courts has now ended up in the European Court of Human Rights, where the judges will decide if Switzerland’s male-only conscription requirement violates anti-discrimination rules. 

Switzerland’s NZZ newspaper wrote on Monday the case has “explosive potential” and has “what it takes to cause a tremor” to a policy which was first laid out in Switzerland’s 1848 and 1874 Federal Constitutions. 

What is Switzerland’s compulsory military service? 

Article 59 of the Federal Constitution of Switzerland says “Every man with Swiss citizenship is liable for military service. Alternative civilian service shall be provided for by law.”

Recruits must generally do 18 weeks of boot camp (longer in some cases). 

They are then required to spend several weeks in the army every year until they have completed a minimum 245 days of service.

Military service is compulsory for Swiss men aged 18 and over. Women can chose to do military service but this is rare.

What about national rather than military service? 

Introduced in 1996, this is an alternative to the army, originally intended for those who objected to military service on moral grounds.

Service is longer there than in the army, from the age of 20 to 40. 

This must be for 340 days in total, longer than the military service requirement. 

What about foreigners and dual nationals? 

Once you become a Swiss citizen and are between the ages of 18 and 30, you can expect to be conscripted. 

READ MORE: Do naturalised Swiss citizens have to do military service?

In general, having another citizenship in addition to the Swiss one is not going to exempt you from military service in Switzerland.

However, there is one exception: the obligation to serve will be waved, provided you can show that you have fulfilled your military duties in your other home country.

If you are a Swiss (naturalised or not) who lives abroad, you are not required to serve in the military in Switzerland, though you can voluntarily enlist. 

How do Swiss people feel about military and national service? 

Generally, the obligation is viewed relatively positively, both by the general public and by those who take part in compulsory service. 

While several other European countries have gotten rid of mandatory service, a 2013 referendum which attempted to abolish conscription was rejected by 73 percent of Swiss voters. 

What is the court case and what does it say? 

Martin D. Küng, the lawyer from the Swiss canton of Bern who has driven the case through the courts, has a personal interest in its success. 

He was found unfit for service but is still required to pay an annual bill to the Swiss government, which was 1662CHF for the last year he was required to pay it. 

While the 36-year-old no longer has to pay the amount – the obligation only lasts between the ages of 18 and 30 – Küng is bring the case on principle. 

So far, Küng has had little success in the Swiss courts, with his appeal rejected by the cantonal administrative court and later by the Swiss Federal Supreme Court. 

Previous Supreme Court cases, when hearing objections to men-only military service, said that women are less suitable for conscription due to “physiological and biological differences”.

In Küng’s case, the judges avoided this justification, saying instead that the matter was a constitutional issue. 

‘No objective reason why only men have to do military service’

He has now appealed the decision to the European level. 

While men have previously tried and failed when taking their case to the Supreme Court, no Swiss man has ever brought the matter to the European Court of Human Rights. 

Küng told the NZZ that he considered the rule to be unjust and said the Supreme Court’s decision is based on political considerations. 

“I would have expected the Federal Supreme Court to have the courage to clearly state the obvious in my case and not to decide on political grounds,” Küng said. 

“There is no objective reason why only men have to do military service or pay replacement taxes. On average, women may not be as physically productive as men, but that is not a criterion for excluding them from compulsory military service. 

There are quite a few men who cannot keep up with women in terms of stamina. Gender is simply the wrong demarcation criterion for deciding on compulsory service. If so, then one would have to focus on physical performance.”

Is it likely to pass? 

Küng is optimistic that the Strasbourg court will find in his favour, pointing to a successful appeal by a German man who complained about a fire brigade tax, which was only imposed on men. 

“This question has not yet been conclusively answered by the court” Küng said. 

The impact of a decision in his favour could be considerable, with European law technically taking precedence over Swiss law.

It would set Switzerland on a collision course with the bloc, particularly given the popularity of the conscription provision. 

Küng clarified that political outcomes and repercussions don’t concern him. 

“My only concern is for a court to determine that the current regulation is legally wrong.”
