Climate change: Global impacts 'accelerating'

The World Meteorological Organization (WMO) says that the physical and financial impacts of global warming are accelerating.

Record greenhouse gas levels are driving temperatures to "increasingly dangerous levels", it says.

Their report comes in the same week as the International Energy Agency (IEA) reported a surge in CO2 in 2018.

This year's State of the Climate report from the WMO is the 25th annual record of the climate.

Paleontologists report world's biggest Tyrannosaurus rex

University of Alberta paleontologists have just reported the world's biggest Tyrannosaurus rex and the largest dinosaur skeleton ever found in Canada. The 13-metre-long T. rex, nicknamed "Scotty," lived in prehistoric Saskatchewan 66 million years ago, according to Science Daily.

"This is the rex of rexes," said Scott Persons, lead author of the study and postdoctoral researcher in the Department of Biological Sciences. "There is considerable size variability among Tyrannosaurus. Some individuals were lankier than others and some were more robust. Scotty exemplifies the robust. Take careful measurements of its legs, hips, and even shoulder, and Scotty comes out a bit heftier than other T. rex specimens."

Dinosaurs could hear as well as birds - making them even better hunters than previously believed, according to new research

Dinosaurs could have sensed sound as sharply as birds, making them even better hunters than previously believed.

The process used by birds to hear has been detected in alligators, which are the closest living relative to the dinosaur, according to Daily Mail.  

It could means that T-rex and other carnivore dinosaurs identified the location of prey with their ears as much as their eyes.

An owls' sense of hearing is so sharp it can hear a mouse moving around under a covering of snow. 

Birds are exceptionally good at creating neural maps of the location of where sounds originated.   

These maps of where the sound came from uses a technique called the 'interaural time difference'.

Study reveals the wolf within your pet dog

Wolves lead and dogs follow - but both are equally capable of working with humans, according to research that adds a new twist in the tale of how one was domesticated from the other.

Dogs owe their cooperative nature to "the wolf within", the study, of cubs raised alongside people, suggests, according to BBC.

But in the course of domestication, those that were submissive to humans were selected for breeding, which makes them the better pet today.

How WOLVES can co-operate with humans just like dogs: Ferocious canines are as capable of following handler's commands - but they show more initiative than domesticated pets

Wolves reared by humans can learn to cooperate with their handlers just as well as domesticated dogs, a new study has found.

Wild wolves work together to hunt, rear their offspring and defend their territory, traits which have been passed down to modern dogs - their closest relatives.

Experts tested the extent to which dogs and grey wolves collaborate with humans in order to solve a range of tasks, according to Daily Mail.

They found that both dogs and wolves cooperate intensively and equally successfully, but wolves show more initiative where dogs follow a human's lead.

The experiment, conducted at the University of Veterinary Medicine Vienna, looked at how wolves and dogs cooperated with humans to solve specific tests.
