A recent encounter between a human diver and a humpback whale has illustrated how concern for the safety of others can reach across species. Marine biologist Nan Hauser was on an expedition to the South Pacific’s Cook Islands to study whales for a film that she is making. But while diving with a humpback whale, her 25-tonne subject appeared to be attacking her, at least at first. But what she learned after extricating herself from the leviathan’s advances made her see the whole situation in a completely different light.

A chance encounter between a malnourished polar bear and the conservation group Sea Legacy provided photographer Paul Nicklen with the chance to document the sad state of a polar bear reduced to scavenging through garbage cans, unable to hunt due to the severe reduction in ice flows caused by global warming.

Nicklen is quite familiar with these bears, having grown up in Canada’s far north, and immediately realized that the bear was in distress. The sight affected the team deeply: "We stood there crying — filming with tears rolling down our cheeks," according to Nicklen.

Although it’s (finally) not raining cats and dogs in Tamaulipas state in northeastern Mexico, on September 26 the coastal city of Tampico reported a rain of small fish from the sky, accompanying a light rainshower.

Although a rare and extremely unusual occurrence, events such as this have been explained as being caused by tornadoes or waterspouts that form over water, sucking fish high into the air, that eventually fall back down in a different area.

Strange phenomena such as this were extensively cataloged by early 20th-century writer Charles Fort, including falls of frogs, fishes, as well as other inorganic materials, leading to the term "Fortean phenomena".

Tokyo Electric Power Company (TEPCO) has announced that they plan dump 777,000 tons of tritium-contaminated water into the Pacific Ocean, as part of their multi-billion dollar recovery efforts at the Fukushima Daiichi nuclear power plant. The total amount of radioactive material involved would be approximately 115 times the annual safety limit for this type of discharge. The move has yet to be approved by the Japanese government, although TEPCO says that they still plan to go ahead with the decision.
