How much does tourism help fund bird conservation? Given the continuing boom of the "avitourism" industry, this sounds like the sort of question to which both environmentalists and entrepreneurs should know the answer.

However, while researchers have performed calculations investigating the availability of tourism revenues for mammal and frog conservation efforts, nobody has explored similar trends in other taxa--or, to be more accurate, nobody had explored those trends until a group of Australian scientists recently decided to crunch the relevant numbers.

The results of their analyses were reported earlier this month in PLoS ONE.

Did you ever have breast milk or spinach? You might as well start shooting up heroin.

If dihydrogen monoxide doesn't scare you enough, food activists have been rehashing an old term - opiates.

As has been mentioned in other articles, evolution is one of the more misunderstood theories ‌in biology.  This isn't because it is complicated.  Its beauty derives from its simplicity, but often the nuances that are overlooked.  

We hear about "survival of the fittest" and many immediately think of strength.  We hear about natural selection and many immediately focus on speciation.  Yet, the first claim is simply wrong, while the second isn't the most important element of the theory.

So, if it's not about strength or how species originated, then what is important.

Social structure is an imposition, but by definition one that ‘should’ be imposed, meaning by the origin of the meaning of “should” in the co-evolution of the social with our language.

A 12-year study (1999 to 2010) analyzed fatality reductions in bicycle-car collisions to determine the effect of mandatory helmet laws. 16 states had bike helmet laws in the beginning or the study. The researchers identified all relevant fatalities, totaling 1612, in states with and without bike helmet laws.
  

Relevance was determined by adjusting for factors previously associated with rates of motor vehicle fatalities (elderly driver licensure laws, legal blood alcohol limit and household income) and, among those, they found that the adjusted fatality rate was significantly lower in states with helmet laws. On average, 900 people die annually in bicycle-motor vehicle collisions — three quarters of those are from head injuries.
