London, December 26, 2016: Listening to sounds such as music and noise has a significant effect on an individuals’ moods and emotions, possibly as a result of brain dopamine regulation — a neurotransmitter strongly involved in emotional behaviour and mood regulation, researchers have found.

However, the differences in dopamine receptors may drive the differences between individuals, the researchers said.

The study revealed that a functional variation in dopamine D2 receptor (DRD2) gene modulates the impact of music as opposed to noise on mood states and emotion-related prefrontal and striatal brain activity.

“Our results suggest that even a non-pharmacological intervention such as music might regulate mood and emotional responses at both the behavioural and neuronal level,” said Elvira Brattico, Professor at Aarhus University in Denmark.

For the study, 38 healthy participants were recruited, with 26 of them having a specific “GG variant” of DRD2 and 12 a “GT variant”. They underwent functional magnetic resonance imaging (fMRI) during performance of an implicit emotion-processing task while listening to music or noise.

The results showed that in participants with DRD2GG receptors the mood improved after music exposure, whereas in GT partipants mood deteriorated after noise exposure.

Moreover, the music, as opposed to noise environment, decreased the striatal activity of GT subjects as well as the prefrontal activity of GG subjects while processing emotional faces.

These findings suggest that genetic variability of dopamine receptors affects sound environment modulations of mood and emotion processing, the researchers suggested.

Importantly, these study encourages the search for personalised music-based interventions for the treatment of brain disorders associated with aberrant dopaminergic neurotransmission as well as abnormal mood and emotion-related brain activity, Brattico said, in the paper published in the journal Neuroscience.

When you're pregnant, the immune system is seeing the placenta for the first time in decades.

The US researchers have discovered a class of immune cells that plays a role in miscarriage, which affects about a quarter of pregnancies.

Researchers at the University of California-San Francisco found that the recently discovered subset of cells known as extrathymic Aire-expressing cells in the immune system may prevent the mother's immune system from attacking the placenta and fetus.

The researchers showed that pregnant mice who did not have this subset of cells were twice as likely to miscarry, and in many of these pregnancies fetal growth was severely restricted.

"When you're pregnant, the immune system is seeing the placenta for the first time in decades -- not since the mother made a placenta when she herself was a fetus," said Eva Gillis-Buck, from UCSF.

"Our research suggests that this subset of immune cells is carrying out a sort of 'secondary education' -- sometimes many years after the better-known population of the educator cells have carried out the primary education in the thymus -- teaching T cells not to attack the fetus, the placenta and other tissues involved in pregnancy," she added. The findings are published in the journal Science Immunology.

It's not surprising that over half of those surveyed feel more comfortable using emojis than talking on the phone or in person.

The tiny emojis being shared on billions of devices worldwide can play a major role in digital communication, with most people saying that emoji compels them to feel more empathy towards others, according to an Adobe report.

Adobe's global emoji study found that emoji even helps people overcome language barriers and form connections that would otherwise be difficult to do.

"We were surprised and delighted by the discoveries made in the survey, most notably how enthusiastic respondents were for emoji as a means to express themselves," the company said in a statement.

Emojis sometimes get criticized for being overly saccharine, but this sweetness is key when it comes to diffusing some of the heaviness of online communication.

"Many of the emoji are focused on positive emotions, so it's easy to insert them into our conversations and lighten the mood," the Adobe study said.

Jeff Bezos at the ENCORE awards.

Following the grand Richard Branson show where he carried Andhra Pradesh-born Sirisha Bandla and fellow space travelers on his shoulders after successfully flying to the edge of space, it is time for Amazon Founder Jeff Bezos to applaud Sanjal Gavande, one of the key engineers who designed the New Shephard rocket set to take Bezos and the crew to space on July 20.

Billionaire Bezos is set to fly to the edge of space aboard what is touted as the world's first unpiloted suborbital flight. Born in Kalyan, Maharashtra, Gavande is a systems engineer at Blue Origin who always dreamt of designing aerospace rockets.
