As planets age the general rule is that they become darker and cooler - but Saturn is an exception. Why it looks so young for its age has been a space science topic since the late 1960s but a paper in Nature Geoscience says it has some answers.

Elsevier and the Integrated Earth Data Applications facility at Columbia University have announced a competition to improve preservation of and access to research data in the earth sciences. 

Members of the international geosciences community who have worked on preservation and improved access of research data, particularly dark data, can share their work and advise on ways that these data are being processed, stored and used. 

Brown and white fat cells in a living organism can be converted from one cell type to the other, according to a study using mice as a model organism.

A drug developed by Gilead Sciences and tested in an animal model at the Texas Biomedical Research Institute in San Antonio suppresses hepatitis B virus infection by stimulating the immune system and inducing loss of infected cells.  

Cancer cells that can break out of a tumor and invade other organs are more aggressive and nimble than nonmalignant cells. Such cells exert greater force on their environment and can more easily maneuver small spaces, researchers write, due to a systematic comparison of metastatic breast-cancer cells to healthy breast cells which revealed dramatic differences between the two cell lines in their mechanics, migration, oxygen response, protein production and ability to stick to surfaces.

“Hark! The Herald Angels Sing” is the beginning to one of the world's most popular hymns, yet while millions of people can oddly identify Nicki Minaj, almost no one knows the name of Charles Wesley or his Hymns and Sacred Poems. “Hark! The Herald Angels Sing” became regarded as one of the Great Four Anglican Hymns and was published as number 403 in "The Church Hymn Book". It has been recorded by everyone from Frank Sinatra to the kids on "Charlie Brown"(1) and now the private letters of the composer have been edited by Dr. Gareth Lloyd of The University of Manchester’s John Rylands Library and Professor Kenneth Newport of Liverpool Hope University and published by Oxford University Press. They provide a rare glimpse into both the man and the birth of Methodism.
