Mona Lisa's enigmatic smile is NOT the result of Da Vinci's model suffering from a brain disorder and she didn't have hypothyroidism as has been claimed, says medical specialist

Claims that the woman who inspired the Mona Lisa suffered from severe hypothyroidism and that her enigmatic smile was due to a muscle-brain disorder are untrue, an expert claims, according to Daily Mail.

In recent years, rheumatologists and endocrinologists examining the famous painting by Leonardo da Vinci have suggested that the woman who sat for the portrait hundreds of years ago suffered skin lesions and swelling as a result of a lipid disorder and heart disease.

But Dr Michael Yafi from the University of Texas says there was likely nothing wrong her - and she would have shown more visible symptoms if she was suffering from these medical problems. 

The painting's discolouration was the most likely explanation behind her yellow skin tone and her asymmetric smile is nothing more than her enigma, he said.

And she may not even have been able to sit for the portrait at the time had she suffered from the associated symptoms of muscle weakness.

Think women can't drive as well as men? Think again! Study of professional racers finds females are genetically BETTER at dealing with the extreme conditions at the wheel

Female drivers in the world of auto-sport are genetically wired up to deal with the extreme conditions better than their male peers, according to Daily Mail.

A study found that there is no difference between the physical fitness of males and females but women, with suitable training and experience, could become faster. 

Debate over the differences in physical performance has raged for a long time as to whether women are as capable of enduring the brutal conditions at the wheel.

It also dispelled a common and unfounded myth that women are less tolerant of the high temperatures involved in Motorsport at a certain point.

Music captivates listeners and synchronizes their brainwaves

Music has the ability to captivate us; when listeners engage with music, they follow its sounds closely, connecting to what they hear in an affective and invested way. But what is it about music that keeps the audience engaged? A study by researchers from The City College of New York and the University of Arkansas charts new ground in understanding the neural responses to music, according to Science Daily.

Despite the importance, it has been difficult to study engagement with music given the limits of self-report. This led Jens Madsen and Lucas Parra, from CCNY's Grove School of Engineering, to measure the synchronization of brainwaves in an audience. When a listener is engaged with music, their neural responses are in sync with that of other listeners, thus inter-subject correlation of brainwaves is a measure of engagement.

Actors lose their sense of self when they are in character, psychologists say

Actors lose their sense of 'self' when they take up a character, new research has shown. 

Experts asked theatre students to get into character before the study began.

They were then asked a series of questions and asked to respond as either themselves, a character, how they thought a friend would react, or in a different language.  

Scans revealed changes in two areas of the front of the brain that are linked to a person's sense of 'self', according to Daily Mail.

No wonder they're man's best friend! Study finds dogs' personalities often end up mimicking their owners' traits as they change over time

It’s said you can’t teach an old dog new tricks. But, when it comes to personality, it seems dogs continue making progress throughout their lifetime.

A new study has found that dogs’ personalities may change over time – and even tend to line up to match their owner’s.

The findings upend previous assumptions that dogs’ personalities are generally unchanging due to the overall stability of their lives ,according to Daily Mail.

According to the researchers, the results suggest dogs experience personality changes similar to how humans do over the course of their lives.
