Female American athletes get less coverage in the media due to gender bias and instead what attention they get focuses more on attire, or how attractive, sexy or ladylike they are, write Emily Kaskan and Ivy Ho of the University of Massachusetts Lowell in Sex Roles, an interdisciplinary behavioral science journal offering a feminist perspective. 

Kaskan and Ho looked at how pervasive small subtle biases and stereotyping of American female athletes are and what types of "microaggression" exist, examining how they put pressure on athletes and other women, as well. They reviewed popular Internet articles and research from the Psychinfo database, using keywords such as 'sexism,' 'sports media,' 'Serena Williams' and 'Olympic coverage.'

America talks a lot about body image, but only as it relates to girls. The war on thin women is in full swing, obesity is all the rage. Even lingerie companies have plus-sized models and when a European engineer wore a shirt that a female artist friend made for his birthday, America was outraged - because it had thin women on it.

Yet these movements are one-sided, to a point they might be considered sexist. Young males are the forgotten demographic, even though a new study finds that up to 25% of boys are on diets, whether they need them or not. Almost one third of male adolescents inaccurately perceive their own weight.

Cold-climate researchers at Washington State University are clearing the road with 'green' alternatives to salt.

In the 1960s, there was talk of a dystopian future where the masses starved because the ghost of Malthus came home to roost and the world could no longer feed its people.

Instead, Norm Borlaug and science ushered in a "Green Revolution" and countries that embrace science, like America, have reduced environmental strain while producing more food than ever dreamed possible. One other interesting effect the boost in agriculture has had: changing the amplitude of atmospheric carbon dioxide by about 15 percent during the last five decades. 

A new atmospheric model called VEGAS estimates that on average, the amplitude of the seasonal oscillation of carbon dioxide in the atmosphere is increasing at the rate of 0.3 percent every year. 

The Earth has a magnetic field that functions as an in-built force-field against galactic cosmic rays, particles from space which prompt a chain-reaction of events in thunderclouds that trigger lightning bolts. 

The only thing more powerful than our magnetic field is that of the Sun, and it may be playing a part in the generation of lightning strikes on Earth by temporarily 'bending' the Earth's magnetic field and allowing more energetic particles to enter the upper atmosphere. Over a five year period, the UK experienced around 50% more lightning strikes and researchers found that correlates to when the Earth's magnetic field was skewed by the Sun's own magnetic field.

Each year, the biosphere balances its atmospheric budget: The carbon dioxide absorbed by plants in the spring and summer as they convert solar energy into food is released back to the atmosphere in autumn and winter. Levels of the greenhouse gas fall and rise with growth and harvesting.
