Phys.org / DNA evidence reveals a Stone Age population collapse in France
By analyzing DNA of ancient skeletons at a Neolithic burial site near Paris, an international team of researchers has uncovered evidence of a dramatic population replacement 5,000 years ago. The findings indicate that the ...
Phys.org / Decoy molecules trick soil bacteria into attacking persistent pollutants without genetic engineering
In a study published in the Journal of Materials Chemistry A, Nagoya University researchers demonstrated that native soil bacteria, when treated with decoy molecules, can degrade non-native compounds, including persistent ...
Medical Xpress / A year after forgiving, people report stronger mental health and pro-social character
Can forgiving someone today leave you with an improved sense of well-being a year from now? A new study of residents of 22 countries says yes. The caveat, though, is that the size of the impact varies by nation, as does its ...
