With every discovery in this field of particle physics in the past 50 years, however, more questions arise about how quarks influence the universe's growth and ultimate fate. Here are seven strange facts about quarks.

Twin pandas born at the Smithsonian's National Zoo would have been fraternal brothers, if the firstborn cub hadn't died just five days after making its debut on Earth.

You don't have to be a Kardashian to stand out on the Internet — all you need is at least 20 pairs of bright-yellow legs, a gleaming red head and venomous fangs.

I'm not sure if this is poor science, or poor reporting. Some issues -

- The mentioned reduction looks like a total reduction, rather than the reduction attributable to cannabis. As a lot of the cannabis smokers in the study also smoked tobacco, that's an important 'oversight'. Smoking tobacco has been shown to damage male fertility in numerous studies - a 10 to 30 percent drop just from tobacco wouldn't be terribly surprising. They say they account for it, but it's highly unlikely we're being given that figure. From the dosage they were looking at I'd expect a range of 1 to 5 percent, probably closer to 1, though.

- Have they really accounted for tobacco? Surely they could have found some non-smoking cannabis users? Tobacco is a huge confounding factor. Furthermore, they don't seem to have checked general health levels - they even admit these factors could play a causal role. Seriously? These are things that can be controlled for.

It seems pretty flimsy to me. Without seeing the paper it's impossible to tell if they've found anything at all.

To be clear, I'm not saying cannabis doesn't affect male fertility, it may well do. I'm saying this is dubious evidence.

As the human population continues to inch closer to 8 billion people, feeding all those hungry mouths will become increasingly difficult. A growing number of experts believe that we'll soon have no choice but to start eating insects.

If we keep growing in population, there will be no choice but to eat... each other. :-)
