Does the "dark triad" make you a personality trait more successful?

The dark side of the human personality has long been fascinated by the public and psychologists. The research has linked unpleasant traits such as selfishness and a lack of empathy towards higher income and better prospects for landing. But in a new study, scientists argue that such work is often superficial, statistically weak and represents an overly simplistic view of human nature.

Men who lived in Spain 4,500 years ago today have left almost no male genetic inheritance

The genetic inheritance of men living in the Pyrenees 4,200 years ago has largely diminished – all their and chromosomes, which are transmitted from men to men, have been replaced by new agricultural cultures included in the region and thrown out of the genofund. This is one of the striking conclusions of the largest analysis of the ancient DNA from the Iberian peninsula.

These weird, scaled mammals are the most expensive in the world – and they could be extinct

International conservation groups and government agencies are intensifying their efforts to preserve pangolins, mammals facing the bleak future as the most desirable animal in the world. They also asked for their own meat and for their scales, believing they had medicinal properties in some Asian countries. In the past two months, pangolin records in Asia and Africa have been recorded.

Trump again seeks deep cuts in the consumption of science in the United States

For the third year in a row, President Donald Trump's administration has announced to the Congress a budget request that calls for deep cuts in spending in many federal scientific agencies, including a 13% cut in the National Institutes of Health and a 12% reduction for the National Health Institution Foundation for Science, while it provided enormous increases for the army.

New fuel cells can help solve problems with the storage of renewable energy

Transition to renewable energy means technology that can convert electricity from the wind and the sun into chemical storage fuel and then convert this fuel into electricity. Commercial devices that do this exist, but most of them are expensive and only perform half the equation. Now researchers have created laboratories that work both jobs. If larger versions work, they will help enable – or at least be more accessible – to manage the world on renewable sources.
