Satellite galaxies. Dark matter. Simulating the unknown...
The mystery of the missing satellite galaxies has bedeviled astronomers for more than a decade. While dark matter has proven to be exceptionally good at explaining the formation of large galaxies and clusters, it routinely runs into trouble when attempting to describe tiny structures such as satellite galaxies. Dozens of tiny galaxies known as satellite…

Dogmas, science, assumptions and the need for Philosophy!
Horgan: What’s your opinion of the recent philosophy-bashing by Stephen Hawking, Lawrence Krauss and Neil deGrasse Tyson? Rovelli: Seriously: I think they are stupid in this. I have admiration for them in other things, but here they have gone really wrong. Look: Einstein, Heisenberg, Newton, Bohr…. and many many others of the greatest scientists of…

Watch out for the assumptions...
A new study from scientists at the University of Miami Rosenstiel School of Marine and Atmospheric Science and colleagues confirms rising levels of water vapor in the upper troposphere -- a key amplifier of global warming -- will intensify climate change impacts over the next decades. The new study is the first to show that…

DNA. epigenetics, gods...
Researchers at the BBSRC-funded Babraham Institute, in collaboration with the Wellcome Trust Sanger Institute Single Cell Genomics Centre, have developed a powerful new single-cell technique to help investigate how the environment affects our development and the traits we inherit from our parents. The technique can be used to map all of the 'epigenetic marks' on…

Physics constants not so constant. Unless you assume so...
Australian astronomers have combined all observations of supernovae ever made to determine that the strength of gravity has remained unchanged over the last nine billion years. (1) But is this really the case? How solid is such a conclusion? Digging a little deeper makes things more clear... The original paper can be found here. The…
