Black Holes could be a cosmic door to another Universe, Stephen Hawking told a scientific conference in Toronto this week.

A Black Hole, just in case you didn’t know, is a deformation of the fabric of spacetime caused by a star collapsing under the weight of its own gravity.

Scientists have assumed that everything that went into a Black Hole was destroyed, but Hawking postulates that matter can survive and pass into an parallel Universe.

Meanwhile, Cancer cells have been re-programmed back to normal cells, according to researchers at the prestigious Mayo Clinic in the US.

The scientists have found instructor molecules, called microRNAs, which tell cells when to stop dividing, are absent, or not working properly in human cancer cells.

The plan now is to find ways to inject microRNAs directly into tumours to halt, or even reverse cancer, the researchers say.

Whether Violent Video Games trigger criminal aggression has been up for debate for decades, and many scientific studies have tried to find an answer.

This week, the American Psychological Association, said they had reviewed 300 separate studies on this topic between 2005 and 2013.

Their conclusion was that violent video games ARE one of the factors that can lead to criminal aggression, particularly in those with depression and antisocial tendencies.

Body Mass Index (BMI) is a standard way for health professionals to try to measure whether someone is at risk of health problems due to their weight.

However, BMI’s true effectiveness as a way to measure individual health has been questioned by many, who say more accurate strategies are required.

This is an issue of great importance to many Irish people, as, half of all Irish adults, as measured by BMI are either overweight or obese.
