Activists believe that sustained high ($110-120 per barrel) prices will lead to  lower carbon emissions because it will make solar and wind seem viable by comparison, but a new study finds that is not true. Why abandon something where the same margin on an expensive product would lead to incredible profit?

Controlling supply leads to people paying thousands of dollars for diamonds, as an example.

Though diet book authors claim they have a once-size-fits-all solution for weight gain, be it giving up sugar or salt or wheat, the fact is that we have the luxury of being able to eat in excess for a very low cost. 

But 'do everything in moderation' is also ineffective for losing or maintaining weight, because the more people like a food, the more forgiving their definitions of moderation are, 

A paper in Appetite describes the relative meanings attached to moderation based on perceptions, based on surveys.

In the race towards the discovery of another planet in our solar system, the ninth or tenth depending on how seriously you take the 2 percent of astronomers who demoted Pluto, scientists are striving to calculate its potential orbit using the tracks left by the small bodies that move well beyond Neptune.  And the calculations may mean even more than 10 exist.

New calculations confirm that the orbits of the six extreme trans-Neptunian objects that served as a reference to announce the existence of Planet Nine are not as stable as it was thought.

While Greenpeace is using black hat tactics to take out companies that don't submit to their efforts at racketeering, the pro-science community recognizes that renewable wood could be used to replace oil.

Much of te present-day chemical industry is based on oil; products from plastics to detergents and to medication have their origins in oil and its constituents. Yet oil reserves are finite, so scientists have been looking for ways to manufacture these products from sustainable materials, such as wood.

If "Lucy" wasn't alone, and since there is no evidence of spontaneous generation she was not alone, who else was in her neighborhood? Fossil evidence indicates that multiple early human ancestor species lived at the same time more than 3 million years ago, at least four identified hominin species that co-existed between 3.8 and 3.3 million years ago during the middle Pliocene. 

A species of tropical fish has been shown to be able to distinguish between human faces. It is the first time fish have demonstrated this ability.
