Wolves seem to have howl ‘dialects’ — might help unravel origin of human speech

wolf howl

A team of researchers performed the most extensive study of howling made by canid species. This includes wolves, jackals and familiar domesticated dogs. The findings suggest that each species and subspecies has its distinct vocal fingerprint, with a specific pitch, fluctuation and timbre.

Oddly enough, all trees regardless of size break at the same wind speed

In the wake of calamities like hurricanes or tornadoes, you’ll find trees leveled to the ground. But observations suggest that all trees seem to break at the same wind speed, with parameters like the type of tree, height or diameter barely affecting the outcome.

A new study analyzes how much Arctic ice can melt before its grounded portion also starts sliding into the ocean.

Climatic shift in antique times heralded dramatic changes


A period of significant cooling from 536 to 660 AD brought forth massive societal changes in Europe and Asia, a new study found. The cooling, caused by volcanic activity, coincided with a massive plague, the decline of the Byzantine Empire and the spread of Slavic and Arabic people. It is well known that volcanic activity can lead to colder climate, by

You shouldn’t forget about recycling bathroom items


When home recycling is concerned, the kitchen reigns supreme.

These bizarre creatures are called Xenoturbella, and can be found at the bottom of the ocean. For years scientists have being trying to figure out which proverbial foot these fit in. Now, it seems like their place in the tree of life has been established. Not surprisingly, these are found near the base of the tree of bilaterally symmetrical animals. A fancy way of saying one half matches the other half. That’s at least one thing these deep-sea sock creatures have in common with humans.

This fern changed the world 50 million years ago, and it could help us again


Some 50 million years ago, the world was in dire straits. Atmospheric CO2 levels were at over 1000 ppm, with some putting the level at 3500 ppm. Turtles and palm trees were thriving at the poles and sea levels were much higher than they were now as there was virtually no snow to be seen. Future for all life seemed
