Dogs' eyes evolve to appeal to humans

If a dog has eyes that seem to be telling you something or demanding your attention, it could be evolution's way of manipulating your feelings.
Researchers have found that dogs have evolved muscles around their eyes, which allow them to make expressions that particularly appeal to humans, according to BBC.
A small facial muscle allows dog eyes to mimic an "infant-like" expression which prompts a "nurturing response".
The study says such "puppy eyes" helped domesticated dogs to bond with humans.
Previous studies have shown how such canine expressions can appeal to humans, but this research from the UK and US shows there has been an anatomical change around dogs' eyes to make it possible.

How multi-celled animals developed

Scientists at The University of Queensland have upended biologists' century-old understanding of the evolutionary history of animals.

Using new technology to investigate how multi-celled animals developed, their findings revealed a surprising truth, according to Science Daily.

Professor Bernie Degnan said the results contradicted years of tradition.

"We've found that the first multicellular animals probably weren't like the modern-day sponge cells, but were more like a collection of convertible cells," Professor Degnan said.

Largest world stock of animal-killing virus destroyed by UK lab

Scientists have destroyed the UK's laboratory stocks of a virus that once caused devastating cattle losses.

These stocks accounted for most of the world's lab samples of rinderpest, which were held at The Pirbright Institute in Surrey, according to BBC.

Rinderpest and the deadly smallpox virus are the only diseases to have been eradicated from the face of the Earth.

BBC News had exclusive access to the destruction of the final samples.

Dr Carrie Batten, described the moment as "the end of an era".

Scientists close in on hidden Scottish meteorite crater

Scientists think the time has come for a full geophysical survey of The Minch, to see if the Scottish strait is hiding an ancient meteorite crater.

The idea that such a structure lies between the Western Isles and mainland Scotland was first raised back in 2008.

They found evidence on the Highlands coast for the rocky debris that would have been produced by a giant impact.

Now, the researchers believe it can pinpoint where the space object fell to Earth.

UK satellite 'sets sail' for return to Earth

A British satellite in space has just "set sail" to return to Earth.

TechDemoSat-1 was launched in 2014 to trial a number of new in-orbit technologies but has now reached the end of its operational life.

To bring it out of the sky faster than would ordinarily be the case, it has deployed a "drag sail".

This large membrane will catch residual air molecules at its altitude of 635km and pull TDS-1 quickly into Earth's atmosphere where it will burn up, according to BBC.

There is a lot of interest currently in "clean space" technologies.
