We have heard the Mars exploration mantra for more than a decade: follow the water. In a new paper published October 9, 2015, in the journal Science, the Mars Science Laboratory (MSL) team presents recent results of its quest to not just follow the water but to understand where it came from, and how long it lasted on the surface of Mars so long ago.

"John, Jim, Jake, Josh, Jack ...and Jane." Five out of every six names that appear in the media today are those of men, a McGill-led sociology team claims. Indeed, the more mentions a person receives in the media, the higher the chances are that this person is a man. That's because 82 percent of the names mentioned in media are male. 

The scholars combed through data from more than 2,000 U.S. newspapers, magazines, and online news sources covering the period from 1983-2009 for the first time to arrive at this conclusion. 

Despite significant social and economic advances in many fields, there remains a persistent and telling under representation of women in media coverage, something that they refer to as a 'paper ceiling'.

The fishing port of Ondarroa, the Deba marina, the estuary at Gernika (beside the discharge stream of the waste water treatment plant) and the industrial ports of Pasaia and Santurtzi are the scenarios where the research was carried out between May and June 2012.

The fish chosen for the study was the thicklip grey mullet (Chelonlabrosus). Water samples were taken from the above-mentioned locations on the days when the mullet were caught and three months later to relate the samples to the concentrations of the compounds in the fish.

"As we expected, Gernika was where the highest concentration of compounds was found and where the highest number of intersex fish were caught," stressed Asier Vallejo, one of the researchers in the group.

Why elephants rarely get cancer is a mystery that has stumped scientists for decades.  

If your partner has sex with someone else, it is considered infidelity - even if no emotions are involved. But it is also considered infidelity when your significant other develops a close personal relationship with someone else, even if there is no sex or physical intimacy involved.

A recent Norwegian study shows that men and women react differently to various types of infidelity. Whereas men are most jealous of sexual infidelity, so-called emotional infidelity is what makes women the most jealous. Evolutionary psychology may help explain why this may be.
