Lewis Owen has been scraping out icy fragments of history's truth from one of the most glaciated regions on Earth for the past 25 years.

His frequent excursions to Tibet and the Himalayas have led the University of Cincinnati professor of geology to some cold, hard facts.

Owen knows climate change is immortal – fluctuating across millennia, patiently building toward moments when circumstances are ripe for apocalypse. It was true thousands of years ago, when rapid climate change had profound effects on landscapes and the creatures that lived on them. That scenario could be true again, if the past is ignored.

Mathematicians are not created equally. Some people are just better at it, just like Usain Bolt runs faster than, well, everyone.

But a new psychology paper says that some people may be at greater risk to fear math, not only because of negative experiences but also because of genetic risks related to both general anxiety and math skills.

There has long been a hypothesis that a starvation diet can extend lifespan.

The only way it was really shown was by weaning mice on such a diet - and that isn't really ethical for human babies. And it doesn't work in the wild, because dietary restriction compromises the immune system’s ability to fight off disease and reduces the muscle strength necessary to flee a predator. Most animals don't live long enough to catch 'old age' diseases like cancer and the late-life pathologies that humans do.

What do you think about computer-generated news articles? Would you even know?

Recently, Google has tried to penalize 'content farms' - especially companies that look for keywords, terms and trends in searches and automatically generate articles that will show up in search results but are just copied and pasted.

People who smoke high-potency cannabis end up getting higher doses of THC even if they might reduce the amount they puff and inhale to compensate for the higher strength Result: they still take in more THC than smokers of lower potency cannabis.

An area of the canine brain associated with reward responds more strongly to the scents of familiar humans than it does to the scents of other humans, or even to those of familiar dogs.

The journal Behavioural Processes published the results of the first brain-imaging study of dogs responding to biological odors. The research was led by Gregory Berns, director of the Center for Neuropolicy at Emory University.
