If you are an organic food or paleo diet lover and think it means your gut microbiome resembles your ancestors in any way, you are wrong.  We aren't even close to 100 years ago much less ancient times.  The microbiome does not lie.

A team analyzed microbiome data from ancient human fecal samples collected from three different archaeological sites in the Americas, each dating to over 1000 years ago. They also did a new analysis of published data from two samples that reflect rare and extraordinary preservation: Otzi the Iceman and a soldier frozen for 93 years on a glacier. 


Science can make better corn and, well, better everything - except perhaps the Christmas tree.

The genome of conifers like spruce, pine and fir has remained pretty much the same for the last 100 million years - a remarkable feat of genomic stability. Researchers analyzed the genome of conifers and compared it to that of flowering plants. Both plant groups stem from the same ancestor but diverged about 300 million years ago.


The Linac Coherent Light Source (LCLS) at the SLAC National Accelerator Laboratory is using X-rays to measure, in atomic detail, a key process at work in extreme plasmas like those found in stars, the rims of black holes and other massive cosmic phenomena.


Wilms' tumors, a type of cancer typically found in the kidneys of young children, might have a new weapon against them. A new therapeutic approach that one day might be used to treat some of the more aggressive types of this disease could be possible now that  scientists have isolated cancer stem cells that lead to the growth of the tumors.


The Hubble Space Telescope has detected seven primitive galaxies formed more than 13 billion years ago, and also a candidate, at redshift 11.9, for the record for the most distant galaxy found to date. 

The images offer the deepest ever view of the Universe at near-infrared wavelengths, which capture the redshifted light of early galaxies. Because light takes so long to travel from these remote objects, astronomers are looking back in time and seeing those galaxies as they appeared just 600 million years after the Big Bang.


Do you prefer to have a few close friends or a larger social circle that is less deep? Social psychologists say your preference reflect your personality but also individual circumstances - like socioeconomic conditions.
