Did you know that we unconsciously sniff out the perfect partner? And that sniffer dogs – in addition to money and drugs – can detect prostate, ovarian or gastrointestinal cancer from urine samples? The sense of smell is the cover story in the spring issue of Technologist magazine.
Of our five senses, the olfactory sometimes seems like a luxury – hardly essential to our survival. But new research shows that it’s just as essential to us humans as it is to dogs, and that there is a correlation between mortality and the lack of the sense of smell. A large American study has found that a reduced ability to smell is linked to a threefold increased risk of dying within five years.
Although canines still take the lead when it comes to sniffing out smells, the latest research shows that machines such as the e-nose can replace sniffer dogs, for example in airports. You can read about all this and much more in the latest issue of the EuroTech universities' international magazine.
Either too much or too little power
The new issue of Technologist also highlights one of the major challenges related to renewable energy sources: how do we store the energy so it's available when we need it?
If Europe is to become independent of fossil fuels, we need to solve the problem of renewable energy sources producing either too much or too little power. In the special feature on energy storage, you can read about how scientists across Europe are working to resolve this challenge. You can also get acquainted with seven new technologies to store power – from lithium-ion batteries to advanced electromagnetic super-conductors.
