Ever wondered how smart your dog is? Canine IQ test developed by academics

A London university has developed an IQ test for dogs that could pave the way for breakthroughs in our understanding of the links between intelligence and health.

The London School of Economics, along with Edinburgh University, has discovered that dog intelligence functions in a similar way to human intelligence.

Recent studies have shown smarter people tend to live longer.

If scientists can prove this is the same in dogs then they can use them to study long-term health problems such as dementia.

Dr Rosalind Arden, a research associate at the LSE said: "We asked the question, if a dog is good at one test does it tend to be better than average at the other test? And we found that yes that's true.

This is the first step in trying to develop a really snappy, reliable dog IQ test, and that has got implications that aren't obvious at first."

Sixty eight border collies were given a series of cognitive tasks, including finding their way to food behind a barrier and learning to choose a bigger portion of food.


'Wireless pants' to protect against infertility caused by Wi-Fi devices

An inventor from Fulham has launched a range of men's underwear designed to protect the wearer's fertility levels.

Scientist Joseph Perkins says the fabric, which contains silver mesh, protects men from the potentially harmful effects of electromagnetic radiation given off by wireless devices including smartphones and laptops.

Male fertility has declined in recent years and one possible cause is exposure to electromagnetic radiation emitted by Wi-Fi-enabled devices, which has been shown in clinical studies to lower sperm count

A 2014 study by the University of Exeter reviewed previous research investigating the link between electromagnetic radiation and sperm damage. Its findings were not 100% conclusive, but did a show a correlation between exposure to the radiation and poor sperm health.

Inventor Jason Perkins said: "Like so many people, my smartphone and laptop use has increased dramatically in recent years which made me realise that I was exposing myself to large amounts of electromagnetic radiation, mostly centred on my groin.

"With my Physics background I knew there must be a way to shield from electromagnetic radiation using a simple solution."
