A desire to be part of the 'in crowd' could damage our ability to make the right decisions, according to a paper in the
journal Interface which claims that individuals have evolved to be overly influenced by their neighbors, rather than rely on their own instinct.

As a result, they believe, groups become less responsive to changes in their natural environment. So much for the wisdom of crowds.

Divorce rates have gone down; the oft-cited 1970s statistic that 'half of all marriages end in divorce' was never really correct, but the belief that it was made divorce much more common.

More young people today are also avoiding divorce by avoiding marriage. As a result, more than half of all American children will have an unmarried mother - and regardless of all of the cultural whitewashing and rationalizations that cultural apologists engage in, the absence of a biological father increases the likelihood that a child will exhibit antisocial behaviors like aggression, rule-breaking and delinquency. Young boys in that environment are 40 percent less likely to finish high school or attend college, regardless of race.

Illegal aliens who have been deported from the United States are more than 2.5 times more likely to be rearrested after leaving jail, and are likely to be rearrested much more frequently than those who have never been removed, according to a new RAND Corporation analysis.

The new work bolsters federal immigration plans to focus immigration enforcement efforts on immigrants who previously have been removed, because they pose a bigger criminal threat.

The analysts looked at long-term recidivism rates among two groups of removable immigrants who had been released from the Los Angeles County jail: men who previously had been removed from the United States and men who had never been removed from the nation. 

Current carbon capture schemes are not really ready for prime time, plagued by toxicity, corrosiveness and inefficiency, but a team of chemists have invented low-toxicity, highly effective carbon-trapping "sponges" that could lead to increased use of the technology.

Used in natural gas and coal-burning plants, the most common carbon capture method today is called amine scrubbing, in which post-combustion, carbon dioxide-containing flue gas passes through liquid vats of amino compounds, or amines, which absorb most of the carbon dioxide. The carbon-rich gas is then pumped away - sequestered - or reused. The amine solution is extremely corrosive and requires capital-intensive containment.

The Paleolithic diet, eating like our ancient ancestors, is a diet fad that seeks to emulate the diet of early humans during the Stone Age. But what does that mean? Almost anything people want because ancestral diets differed substantially over time and geography, notes a paper in The Quarterly Review of Biology.

The review examines anatomical, paleoenvironmental and chemical evidence, as well as the feeding behavior of living animals. While early hominids were not great hunters, and their dentition was not great for exploiting many specific categories of plant food, they were most likely dietary "jacks-of-all-trades."

Leading conservationists from around the world have called for environmental lobbyists to stop blocking nuclear energy in defiance of the science consensus. It's clean, it's green, and it's needed to mitigate climate change and protect biodiversity.

In an open letter to environmentalists, over 60 scientists ask the environmental community to "weigh up the pros and cons of different energy sources using objective evidence and pragmatic trade-offs, rather than simply relying on idealistic perceptions of what is 'green'".

Organized by ecologists Professor Barry Brook and Professor Corey Bradshaw from the University of Adelaide's Environment Institute, the letter supports their recent article (DOI: 10.1111/cobi.12433) in Conservation Biology.
