Distant galaxy with no dark matter suggests our understanding of the universe could be wrong

Distant galaxy with no dark matter suggests our understanding of the universe could be wrong | levin's linkblog: Knowledge Channel | Scoop.it
In a world first, astronomers have found a galaxy that lacks the enigmatic substance known as dark matter – long considered one of the universe’s fundamental building blocks. Its discovery challenges well-established ideas about how galaxies form, and the nature of dark matter itself. Located 65 million light years away, the snappily named NGC 1052-DF2 galaxy – or DF2 for short – is a “complete mystery” according to the scientists who found it.

Astronaut's DNA changes after spending year in space when compared to identical twin bother | levin's linkblog: Knowledge Channel | Scoop.it
An astronaut who spent a year in space came back changed at a biological level. Early results of Nasa’s Twins Study found that 7 per cent of astronaut Scott Kelly’s genes did not return to their normal state when he returned to Earth two years ago, compared to that of his identical twin brother who never left the blue planet.

Brain activity appears to continue after people are dead, according to new study

Brain activity appears to continue after people are dead, according to new study | levin's linkblog: Knowledge Channel | Scoop.it
Brain activity may continue for more than 10 minutes after the body appears to have died, according to a new study. Canadian doctors in an intensive care unit appear to have observed a person's brain continuing to work even after they were declared clinically dead. In the case, doctors confirmed their patient was dead through a range of the normal observations, including the absence of a pulse and unreactive pupils. But tests showed that the patients’ brain appeared to keep working – experiencing the same kind of brain waves that are seen during deep sleep.

Key symptom of old age reversed 'surprisingly easily', study finds

Key symptom of old age reversed 'surprisingly easily', study finds | levin's linkblog: Knowledge Channel | Scoop.it
The loss of muscle mass and fitness in old age may be reversible by providing the body with a key molecule it needs to rebuild blood vessels, scientists have found. The arteries and capillaries which transport oxygen and nutrients around the body are not replaced as quickly when we’re older and this leads muscles to tire more quickly. Eventually they start to atrophy from under use.

Mysterious origin of domesticated horses ‘turned upside down’ by DNA analysis

Mysterious origin of domesticated horses ‘turned upside down’ by DNA analysis | levin's linkblog: Knowledge Channel | Scoop.it
The horses which have long been considered ancestors of all modern domesticated steeds do in fact, belong to a totally different lineage, genetic analysis has revealed. The oldest known domestic horse population belonged to the Botai people who inhabited the Central Asian steppes around 5500 years ago.  Until now, that population from what is now northern Kazakhstan, has been considered the likeliest source of modern domestic horses.
