Could a multiverse be hospitable to life?

A Multiverse -- where our Universe is only one of many -- might not be as inhospitable to life as previously thought, according to new research.

Questions about whether other universes might exist as part of a larger Multiverse, and if they could harbour life, are burning issues in modern cosmology, according to Science Daily.

Now new research, has shown that life could potentially be common throughout the Multiverse, if it exists.

The key to this, the researchers say, is dark energy, a mysterious "force" that is accelerating the expansion of the Universe.

What will happen when our sun dies?

Scientists agree the sun will die in approximately five billion years, but they weren't sure what would happen next -- until now, according to Science Daily.

A team of international astronomers, including Professor Albert Zijlstra from the School of Physics & Astronomy, predicts it will turn into a massive ring of luminous, interstellar gas and dust, known as a planetary nebula.

A planetary nebula marks the end of 90% of all stars active lives and traces the star's transition from a red giant to a degenerate white dwarf. But, for years, scientists weren't sure if the sun in our galaxy would follow the same fate: it was thought to have too low mass to create a visible planetary nebula.

To find out the team developed a new stellar, data-model that predicts the lifecycle of stars. The model was used to predict the brightness (or luminosity) of the ejected envelope, for stars of different masses and ages.

Prof Zijlstra explains: "When a star dies it ejects a mass of gas and dust -- known as its envelope -- into space. The envelope can be as much as half the star's mass. This reveals the star's core, which by this point in the star's life is running out of fuel, eventually turning off and before finally dying.

Genetic secrets of the rose revealed

Take time to smell the roses, the saying goes, and, according to scientists, the fragrant flowers could smell even sweeter in the future.

For the first time researchers have deciphered the full genetic "book" of this most prized of plants, according to BBC.

The secret history of the rose reveals surprises - it is more closely related to the strawberry than we thought.

And in the long term the work could lead to roses with new scents and colours, says an international team.

The new genome map, which took eight years to complete, reveals genes involved in scent production, colour and the longevity of flowers, said Mohammed Bendahmane of ENS de Lyon, in Lyon, France, who led the research.

Found: A new form of DNA in our cells

It's DNA, but not as we know it.

In a world first, researchers have identified a new DNA structure -- called the i-motif -- inside cells. A twisted 'knot' of DNA, the i-motif has never before been directly seen inside living cells, according to Science Daily.

Deep inside the cells in our body lies our DNA. The information in the DNA code -- all 6 billion A, C, G and T letters -- provides precise instructions for how our bodies are built, and how they work.

The iconic 'double helix' shape of DNA has captured the public imagination since 1953, when James Watson and Francis Crick famously uncovered the structure of DNA.

Horses remember if people smiled or frowned when they last saw them and will avoid those they think are grumpy

Be careful of the long face when you're around a horse.

The intelligent animals remember grumpy people and avoid them if they meet them at a later date, according to Daily Mail.

Horses are so in tune with human emotion that they can detect, and remember,  subtle changes in the facial expressions of humans, the study found. 

The researchers showed photographs of humans making angry or happy faces to the creatures.
