A large number of friends on Facebook has been linked to higher levels of stress, according to surveys compiled by the University of Edinburgh Business School which found that the more groups of people in someone's Facebook friends, the greater potential to cause offense. No surprise, adding employers or parents resulted in the greatest increase in anxiety. 

Alaska's Columbia Glacier, an iconic glacier featured in the documentary "Chasing Ice" and one of the fastest moving glaciers in the world, will cease retreating around 2020, according to a study by the University of Colorado Boulder.

Their computer model predicts the retreat of the Columbia Glacier will stop when the glacier reaches a new stable position, about 15 miles upstream from the stable position it occupied prior to the 1980s.   

NASA's Cassini mission has spotted a second feature shaped like the 1980s video game icon Pac-Man, this time on Saturn's moon Tethys.The pattern appears in thermal data obtained by Cassini's composite infrared spectrometer, with warmer areas making up the Pac-Man shape.

A new substance class for the treatment of multiple sclerosis and other neurodegenerative diseases now promises increased efficacy paired with fewer side effects. To achieve this, a team of scientists have combined two already approved pharmaceutical substances with each other using a chemical linker structure.

A researcher has discovered a critical reason why women experience fertility problems as they get older. The solution could be simple — putrescine water.

Putrescine is naturally produced in mammals by an enzyme called ornithine decarboxylase (ODC) and is easily absorbed and cleared by the body. In female mammals, ODC levels are known to rise during ovulation, when the egg cell matures and is released from the ovary.  Dr. Johné Liu, a senior scientist at the Ottawa Hospital Research Institute and professor at the University of Ottawa, has shown that ODC levels rise very little in older females. He has also shown that inhibiting ODC levels in young mice leads to an increase in egg cells with chromosomal defects. 

Artificial Intelligence (AI) algorithms recently parsed 2.5 million articles from 498 different English-language (online) news outlets over a period of ten months and created data about what was contained.  Could AI qualitatively give people more interesting news?

The results showed what you likely knew - online tabloid newspapers are more readable than broadsheets and use more sentimental language. Among 15 U.S. and U.K. newspapers, The Sun was the 'easiest' to read - comparable to the BBC's children's news program, Newsround - while they found the The Guardian was the most difficult to read.
