Scientists says a new map of the ecological footprint of humankind shows 97 percent of the most species-rich places on Earth have been seriously altered.
For the men out there who can’t help but wonder how they stack up in the size department down under, wonder no more — thanks to a nifty interactive graphic recently released by Target Map. The map, appearing to use data taken from earlier studies, shows how long the average erected penis is on a country by country scale. If you move the mouse over North America, for instance, you'll find the average men there has an erect penis size of 14.2 centimeters (5.59 inches)
When it comes to top honors though, the U.S. and its neighbors are decidedly in the middle of the pack. It's actually men in Western African countries like Ghana who are the biological winners, with the average length upwards of 16 centimeters. On the flip side, men in Asian countries have the smallest lengths, with the average size ranging from 9.3 centimeters (3.6 inches) to 10.5 centimeters (4.1 inches).
Both prescription and illegal drugs can become concentrated in local waterways. New research shows amphetamine levels can become high enough in some urban streams to alter the base of the food chain.
As part of an ecological monitoring project, researchers at the Cary Institute of Ecosystem Studies measured the levels of several drug types in streams in and around Baltimore, Md. A mix of urban and rural sites within the Gwynns Falls watershed were tested.
Traces of several drugs, including amphetamines, were found at all of the sites. The highest concentrations of illegal drugs were measured at stream sites closest to the city of Baltimore.
There’s an oft-quoted rule on the internet: “If it exists, there is porn of it.” Even if that’s an exaggeration, there’s no question that men and women have been consuming more sexually explicit content since the world went online. Now, a new study looks at how this consumption might affect marriage in the United States. The study, a working paper presented this week at the 2016 American Sociological Association’s annual meeting, suggests that men and women who begin to consume pornography partway through their marriages are more likely to get a divorce than their non–porn-consuming peers.
The search for habitable, alien worlds needs to make room for a second "Goldilocks," according to a Yale University researcher …
A new study, appearing in the journal Science Advances, suggests that simply being in the habitable zone isn't sufficient to support life. A planet also must start with an internal temperature that is just right.
In a culture that values youth, aging can seem like a dismal prospect. But a new study suggests that older adults are generally less stressed and happier with their lives than younger people are.
The study, which included adults ages 21 to 99, found that on average, mental well-being steadily improved as people grew older. And that was despite the fact that older adults had more physical health issues and problems with memory and thinking, versus younger people.
The reasons are not completely clear. But researchers pointed to some likely explanations — including the perspective and "wisdom" that comes from life experience.
Scientists have used satellite images to study how the water on the Earth's surface has changed over 30 years.
They found that 115,000 sq km (44,000 sq miles) of land is now covered in water and 173,000 sq km (67,000 sq miles) of water has now become land.
The largest increase in water has been on the Tibetan Plateau, while the Aral Sea has been the biggest conversion of water to land.
The team said many coastal areas have also changed significantly.
