Today, scientists from the University of Leicester are driving the streets in electric vehicles (EV’s) fitted with specialized air monitoring sensors, with the intention of measuring the extent of air pollution in city environments. 

Where do electric vehicles get their electricity? From fossil-fuels that create pollution, using resources less efficiently than gasoline-powered engines.  Like with the head of the American EPA flying all over the country during Earth Week, the irony is not lost on the group, who instead weighed the issues and unsurprisingly decided what they wanted to do was going to bring more benefit than harm.

The gay marriage movement may seem like a modern development but it had its roots in World War II culture. By having homosexual characters in comedies, the concept was less threatening and still passed the censorship of film boards.

An article in the journal Zer by 
Carlos III University of Madrid professor in journalism Alejandro Melero studied the presence and visibility of the gay world in Spanish cinema between 1940 and 1975 - the era of fascist dictator Ferdinand Franco. It shows that there were genres that homosexuality appeared in more frequently. One such genre is comedy, in which it was common to portray gays as funny characters.

In cosmology, cold dark matter is believed to be a form of matter which moves slowly in comparison with light and interacts weakly with electromagnetic radiation. It is estimated that only a minute fraction of the matter in the Universe is baryonic matter, which forms stars, planets and living organisms. The rest, comprising over 80%, is dark matter and energy.

Unwed parents are becoming more common - some estimates are that more children will be born out of wedlock than in it by 2016. Unwed parents may eventually get married, though perhaps not to the person they first had children with.

Researchers have identified a biomarker that predicts whether glioblastoma – the most common form of primary brain cancer – will respond to chemotherapy.  

"Every patient diagnosed with glioblastoma is treated with a chemotherapy called temozolomide. About 15 percent of these patients derive long-lasting benefit," said Clark C. Chen, MD, PhD, vice-chairman of Academic Affairs, Division of Neurosurgery, UC San Diego School of Medicine and the study's principal investigator. "We need to identify which patients benefit from temozolomide and which another type of treatment. All therapies involve risk and the possibility of side-effects. Patients should not undergo therapies if there's no likelihood of benefit."

Locusts decide the most nutritious plant to eat based on ambient temperature - they choose their food and then where they digest it according to how hot it is.
