Aggressive and Sexual Behaviour Overlap in Male Brains: Study

New York, Sep 19, 2017: Brain structures that control aggressive and sexual behaviour are controlled differently in females, but they tend to overlap in males, a new study has found.

Male circuits for sex and aggression were earlier traced to a distinct part of the hypothalamus, known as the ventromedial hypothalamus, or VMHvl — located on the underside of the hypothalamus in both mice and humans.

The study, conducted on mice, showed that the cells controlling these behaviours are separate in female mice, in both those that have not mated and are new mothers.

While the cells for aggression are close to the centre of the hypothalamus, cells for sexual behaviour are at the edge.

“But in the male, the cells are totally mixed up and overlapped,” said Dayu Lin, Assistant Professor at NYU Langone Health in New York, US.

Having a detailed breakdown of brain functions by gender, is a “fundamental step” toward any future attempt to develop drugs that suppress extreme aggression in humans, Lin added in the paper published in the journal Nature Neuroscience.

Further, the researchers found that turning VMHvl cells on or off did control whether female mice would fight.

Experiments showed that the VMHvl cells that females actively used for transmitting signals, or “firing,” while mating were different from the cells used when they were fighting.

But in male mice, many of the same cells were firing during both activities, the researchers said.

London, Nov 20, 2016: The craze for wireless internet connection has gone up so much that almost half of the people now crave for Wi-Fi on the go even more than chocolate, alcohol and, yes, sex, show results of a new survey.

The ever-increasing influence of Wi-Fi on our daily lives was revealed in a recent survey of more than 1,700 people conducted by iPass, a leading provider of global mobile connectivity

The results showed that while 40 per cent of respondents chose Wi-Fi as their number one daily essential, 37 per cent chose sex, 14 per cent preferred chocolate and only nine per cent prioritised alcohol.

“We all want Wi-Fi first, because of faster speeds, lower prices and the better user experience it affords,” said Patricia Hume, Chief Commercial Officer of iPass.

Nearly 75 per cent of respondents said that Wi-Fi has improved their quality of life, according to “The iPass Mobile Professional Report 2016”.

For mobile professionals who do not want to be stung by data bills or exorbitant roaming charges, Wi-Fi has also become a travel essential, influencing hotel, airport and other travel choices.

The survey showed that 72 per cent of respondents have chosen a hotel based on the Wi-Fi experience, with 21 per cent saying they do so all the time. It also showed that 72 percent respondents use free Wi-Fi at airports if it is available.

“Mobile professionals, in particular, expect to remain connected at all times, whether at home, travelling between client meetings, at their hotel or even inflight,” Hume added.

Sixty per cent of the respondents for the survey came from North America, and 40 per cent were from European countries.

“The Wi-Fi experience is increasingly affecting mobile professionals’ travel choices, even at 30,000 feet, with more than a third of respondents having selected their airline based on its Wi-Fi connectivity offerings,” Hume pointed out.

“Long gone are the days when Wi-Fi was only a ‘nice-to-have’ at airports and inflight. Mobile professionals are no longer content to sit and wait for their flights. Instead, they want to remain productive or simply unwind during this valuable time,” Hume said.(IANS)

October 26, 2016: The Narendra Modi Government has decided to discard the usage of the word ‘sex’ from the sex education programme at the school level and HRD (Human Resource Development) Ministry has forced a panel of experts to condense it into one sentence. They said, that words like ‘sex’ or ‘sexual’ could not be allowed and the section had to be condensed into just one sentence.”

Look for latest news from India in NewsGram.

HRD has also asked to abandon the use of words such as ‘sex’ and ‘sexual’ in the document for framing the policy on sex education for the students and said that the mention of the word ‘sex’ in the document might offend people, mentioned mensxp.com report.

NewsGram brings to you latest new stories in India.

According to the Telegraph, when Smriti Irani had headed the HRD Ministry, the original draft which was given out in May used the word ‘sex’ twice.

Later it was reported that the expert panel has been asked to reduce the recommendations on adolescent education and asked not to use phrases like “sexual health needs,” as the word ‘sex’ is a taboo in India and instead of taking a step ahead and working forward to eradicate this, to the surprise, the government says, the mention of this word in the document might not be liked by people and offend them.

On the other side, experts have requested and urged upon a more explicit form of education where sex is talked about freely which will help solve the existing issues in this part of our lives.

According to the reports, the half a page in the draft earlier mainly advocated more thorough and explained lessons against unprotected sex but the Ministry raised objections on this as well during the last round of discussions.

he U.N. Children’s agency warns that the smallest people are often the biggest victims in the global refugee and migration crisis.

“There are nearly 50 million children in the world that are either refugees, migrants or internally displaced,” Unicef Deputy Executive Director Justin Forsyth told reporters at a briefing on the new report.

He said of that number, 28 million children have fled violence or conflict. “That is a near doubling of child refugees in the last decade. It is a tripling of the numbers of unaccompanied children,” he said. “It’s a growing crisis; it’s a children’s crisis.”

Children are especially vulnerable to sex traffickers, criminal gangs and human smugglers when they are on the move.

Last year, almost half of all registered refugee children came from just two countries – Syria and Afghanistan. But this crisis affects children from all parts of the world, including Central America, Asia and Africa.

The report notes that when and if children reach destination countries, the threats they face often do not disappear, leaving them in continuing need of assistance and protection.

UN summit

Later this month, as world leaders gather in New York for the annual U.N. General Assembly, there will be two separate summits on migration and refugees.

UNICEF’s Forsyth said he hopes the summits will result in clear commitments and practical measures for children in these circumstances, including on how to keep families together and making sure displaced children have access to health care and education.

The UNICEF report calls for addressing the root causes of migration and refugees, mainly conflict, violence and extreme poverty. It also urges measures to prevent xenophobia and discrimination against refugees, in addition to measures to prevent exploitation and abuse of children on the move. (VOA)
