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.

The Windows® NTFS disk filing system was first introduced in 1993, but despite its undoubted sophistication, not everyone is convinced that it is perfectly tuned for all possible eventualities. Prompting Dr. Fanglu Guo and Dr. Tzi-cker Chiueh from Symantec Research. Laboratories, Culver City, USA to develop their DAFT disk operating system.

As a researcher in the fields of exact science and philosophy, I am obsessed with “truth”, which is a label of approval we assign to concepts that we judge to be consistent in a certain sense (Example 1 below). How we do that is thus important for the progress of these disciplines.

Love: An Almost Scientific Investigation


What Is Love ?

If I could answer that long-standing question in precise scientific terms with error bars I would be sure to get a Nobel prize and lynched.

Direct current (DC)

In a DC (direct current) circuit where the electricity flows in one direction, we can think of a battery as a storage tank like the water tower in your neighborhood. If nobody turned on their faucet, the water in the tower would just sit there. Forever. Physicists like to think of this as "potential energy." Like a boulder at the top of a hill, it will just sit there, forever, until someone pushes it over the hill or an earthquake shakes it from the top of the hill or erosion undermines it starting it to roll down the hill. When the boulder is rolling down the hill, physicists like to think of this as kinetic energy. So, the water will just sit in the top of the water tower until you turn on the faucet to your water hose.

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. 

There is no question that increased use of natural gas has been good for the atmosphere - energy CO2 emissions are down to early 1990s levels in America and coal is at early 1980s levels of emissions, just like we all said we wanted.

Enhanced extraction methods like hydraulic fracturing - fracking - have also been good for the local economies in places like Pennsylvania. But as with any industry, Not In My Backyard (NIMBYism) occurs in residents of Pennsylvania just like it does yacht owners in Massachusetts. 

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.

ATLAS has just produced a very nice new study of jet production in Z-boson events. I will describe a sample graph below, but before I do I find it useful to explain to the less knowledgeable among you what a hadronic jet is, just in case you've been away during the last forty years.

Hadronic Jets: what are they ?
