Men DO fake 0rgasms :They do it out of love, kindness and sexual insecurity

It has long been known that women can be guilty of faking the throes of passion in the bedroom, but a surprising number of men feign 00rgasms too, according to research carried out by a Harvard academic.

In his new book ‘Why Men Fake it: The Totally Unexpected Truth’, clinical professor of urology Dr Abraham Morgentaler, recounts numerous stories of men confessing that they pretend to clim*x. 

But the biggest shock was their reasoning.

Exhaled breath is unique fingerprint

Compounds present in exhaled breath can act as a "fingerprint" for individuals, scientists say.
These "metabolites" represent the waste products of the body's chemistry - but their uniqueness had never been shown.
A study in PLOS ONE suggests they could be as useful to medical diagnosis as those found in urine or blood.

Because a breath test is non-invasive and the results are instantaneous, it could prove even more convenient for example in anaesthesia or doping tests.
"I don't understand why breath hasn't been a widely used [means of] medical science diagnosis," said the study's lead author Renato Zenobi of the Swiss Federal Institute of Technology (ETH) in Zurich.

Male baldness 'indicates heart risk'

Men going thin on top may be more likely to have heart problems than their friends with a full head of hair, according to researchers in Japan.

Their study of nearly 37,000 people, published in the online journal BMJ Open, said balding men were 32% more likely to have coronary heart disease.

However, the researchers said the risks were less than for smoking or obesity.

The British Heart Foundation said men should focus on their waistline, not their hairline.

A shifting hairline is a fact of life for many men. Half have thinning hair by their 50s and 80% have some hair loss by the age of 70.

Body's anti-HIV 'training manual' offers vaccine hopes

HIV mutates in order to survive the onslaught of a patient's immune system.
However, some patients develop highly effective antibodies that can neutralise huge swathes of HIV mutants.

A North Carolina team analysed the arms race between body and virus, published in the journal Nature, and has shown how these antibodies are made.
When someone is infected with HIV, their body produces antibodies to attack it. But the virus mutates and evades the offensive, so the body produces new antibodies that the virus then evades and the war goes on.

However, after about four years of this struggle some patients hit on to a winner by targeting something the virus finds harder to change - an Achilles heel.
"Even though the virus mutates and there are literally millions of quasi-species of virus because of all these mutations, but there are parts the virus can't change otherwise the virus cannot infect - these are the vulnerable sites," Prof Barton Haynes, of Duke University, in North Carolina.

At this stage of the infection it is far too late to make a difference for the patient as the virus is hiding in untouchable reservoirs.
However, some researchers believe that vaccines that encourage the body to produce these "broadly neutralising antibodies" may give people immunity to the virus.
Super antibody

The research team's study is based on a patient in Africa who had a rapid diagnosis, about four weeks after being infected with the virus.
They were eventually able to produce an antibody named CH103 that could neutralise 55% of HIV samples.

It was not produced in one easy step. Rather it was the product of the war of the immune system and HIV trying to out-evolve each other.
However, through regular genetic analyses of both the immune system and virus, researchers could piece together each of the steps that culminated in the production of CH103.
It is like a training manual for the immune system.

Prof Haynes said: "What we were able to do was map out the arms race of both virus and antibody, and in doing so we have now a map.
"This is the first time we've been able to see the actual road map."

He said the challenge now was to see if re-creating those steps could lead to a viable vaccine.
However, he said it would almost certainly need to be a vaccine combining multiple "Achilles heels" - in the same way that HIV therapies are a combination of drug treatments.

Prof Jane Anderson, consultant at Homerton hospital in London and chair of the British HIV Association, said: "The study gives important insights into the ways in which the human immune system responds to HIV infection and increases our understanding about the relationships between the virus and the human host.

"This is another welcome step on the path to develop vaccines against HIV."
Dr Sarah Joseph, who tests HIV vaccines at the Medical Research Council clinical trials unit, said: "This paper is really interesting. Some people do make antibodies that neutralise a lot of HIV virus, bit it is not of use to them as they produce it way too late."
She said harnessing these antibodies "could be a big deal" and there was "even talk about mass-producing antibodies and infusing people with them".
