Six years ago, we posted about research that documented that when dogs defecate, they usually align their bodies along the magnetic north-south axis, not unlike the needle of a magnetic compass. It turns out that dogs are not unique in being able to sense the earth’s magnetic field and act like bio-compasses. Many animals, including humans, appear to be magnetoreceptive.
Scientists have documented that cows and deer graze and rest aligning themselves with magnetic north, all other factors being equal. (Wind and sun also affect the directions faced by cows, in particular.)
One of the better ways to tell if a model works at predicting the future is to run it in reverse to see how well it predicts the past. Climate change models so far have had their limitations. Most current 
In addition to more than 24 people who have died in the terrible Australian bushfires, an incredible number of animals have also perished. Estimates of wildlife deaths range from

Good ideas are rarely new. Container ships revolutionized liner shipping in the 1960s and 70s. Nevertheless, the idea of carrying cargo in easily handled standardized containers goes back at least 2,000 years.

The temperatures in Australia have been hotter than ever recorded in history. Wildfires are raging, filling the air of several cities, including Sydney, with acrid smoke. Drought is choking a significant portion of the country.
