The famous film star and singer Ali Zafar has said that he is going to
make his upcoming film in Pakistan for which it is very much necessary
to speed up the work. He also said that this time he will give chance to
new and talented youngsters for upcoming film. There is a lot of talent
within Pakistani youth especially in the field of showbiz, Ali Zafar
Argued.
According to him these talented youngsters have no ground to practice and show their skills.
That’s why many artists are leaving country and joining other film industries. And this also a big
reason for the downfall of the Pakistani film industry, Model Turned Actor said.
Ali Zafar also revealed that Katrina has desired to visit Pakistan but can’t
do that because of the insecurity in the country. 
While talking to a local news channel in a hotel, Mr. Zafar told that working in India has its own fun.
He also added that his recent film “Total Siyappa” is going to be released on 7th of March in India
and Pakistan.
The 33-year-old singer finished his talk by adding that if the situation of Pakistan would get better
it would be a good achievement especially for the showbiz stars of both countries to know each
other.

Daisy Coleman rape case: Maryville teenager's case that divided town to be reviewed

A 16-year-old American girl who attempted suicide after she was bullied for accusing two high school seniors of rape will have her case reviewed by a special prosecutor.
Daisy Coleman was a straight-A student and a cheerleader.
On a winter's night two years ago, Daisy and best friend Paige Parkhurst sneaked out to meet some boys - friends of her brothers and high school athletes - in her home town of Maryville, northern Missouri.
She was plied with alcohol and passed out.
Daisy's mother, Melinda Coleman, found her the next morning dumped on the frozen ground in her front yard.
"She was just pretty much not moving. [She] couldn't really speak," she told 7.30.
"She had frostbite on her feet, [which] were starting to turn grey.
"It wasn't until we went to the hospital and the doctor examined her and said she'd been assaulted that we really started to figure things out."
A 17-year-old boy was charged with sexually assaulting Daisy.
A 15-year-old boy was charged with sexually assaulting Paige and was later sentenced in juvenile court.
A third boy confessed to videotaping the incident on his iPhone. There are reports the video was passed around at Daisy's school.
Despite the weight of evidence, local police refused to prosecute the 17-year-old and the boy who filmed the incident.
The events of the past two years have polarised the local community, but Daisy has been applauded for going public in her fight for justice.
"I wasn't really conscious of it in the beginning but as time passed I started receiving a lot of Facebook messages, emails, messages on Twitter, people adding me on Instagram, any way they could get a hold of me," she told 7.30.
"People were writing me letters constantly. I think I've received almost 20 letters now and it's just really amazing that I've impacted that many people's lives."
Daisy's mother says it was obvious her daughter would not have been able to give consent.
"They only had her for 55 minutes. I have copies of the police report and [all of the boys] admit she was unconscious. She couldn't speak, she couldn't move," Melinda Coleman told 7.30.
"They carried her to the car and they carried her to the yard."

Top 13 Effect of Kissing You Would’nt Believe

1)  Long kisses are beneficial to our circulatory system. When kissing, our pulse rate is quickening up to 110 beats per minute. This is a great training for our cardiovascular system.
2) After kissing, the lungs work harder, resulting in 60 inhales per minute compared to regular 20 inhales. Such “ventilation” is a good preventive measure against lung diseases.
3) Some dentists believe that kissing is a preventive measure against dental caries. Indeed, kissing stimulates the flow of salvia that eliminates acid coat on the teeth.
4) Kisses that last more than three minutes help us fight stress and its effects. Long kisses trigger the chain of biochemical reactions, which destroys stress hormones.
5) Those who kiss their partner goodbye each morning live five years longer than those who don’t.
6) Kissing is great for self-esteem. It makes you feel appreciated and helps your state of mind.
7)  Kissing burns calories, 2-3 calories a minute and can double your metabolic rate. Research claims that three passionate kisses a day (at least lasting 20 seconds each) will cause you to loose an entire extra pound.
8)  Kissing is a known stress-reliever. Passionate kissing relieves tension, reduces negative energy and produces a sense of well being, lowering your cortisol ‘stress’ hormone.
9)  Kissing uses 30 facial muscles and it helps keep the facial muscles tight, preventing baggy cheeks! The tension in the muscles caused by a passionate kiss helps smooth the skin and increases the circulation.
10)  Kissing is good for the heart, as it creates an adrenaline which causes your heart to pump more blood around your body. Frequent kissing has scientifically been proven to stabilize cardiovascular activity, decrease blood pressure and cholesterol.
11)   Those who kiss quite frequently are less likely to suffer from stomach, bladder and blood infections.
12)   During a kiss, natural antibiotics are secreted in the saliva. Also, the saliva contains a type of anesthetic that helps relieve pain.
13) Kissing reduces anxiety and stops the ‘noise’ in your mind. It increases the levels of oxytocin, an extremely calming hormone that produces a feeling of peace.
That is it; I hope you love it, so, put more effort into kissing from now on.

Sexual side-effects of antidepressant and antipsychotic drugs

Adequate sexual expression is essential to many human relationships and provides a sense of physical, psychological and social well-being. Epidemiological and clinical studies show that depression and schizophrenia are associated with impairment of sexual function and satisfaction, even in untreated patients. Most antidepressant and antipsychotic drugs have adverse sexual effects but it is difficult accurately to identify the incidence of treatment-emergent dysfunction, as disturbances can be reliably detected only from systematic enquiries made at baseline and during treatment. Growing awareness of the adverse effects of psychotropic drugs has led to attempts to use adjuvants or substitute treatments to resolve sexual dysfunction. More studies of the effects of antidepressant and antipsychotic drugs on sexual function are needed.
The normal sexual response is conventionally divided into the four phases listed below, and disorders can occur at one or more of these phases.
  1. Desire: typically this consists of fantasies about, and the desire to have, sexual activity.
  2. Excitement: a subjective sense of sexual pleasure and accompanying physiological changes, namely penile tumescence and erection in men and pelvic vasocongestion, swelling of the external genitalia, vaginal lubrication and expansion in women.
  3. Orgasm: this is when sexual pleasure peaks, with release of sexual tension and rhythmic contraction of the perineal muscles and reproductive organs. In men, the sensation of ejaculatory inevitability is followed by ejaculation of semen. In women, contractions of the outer third of the vaginal wall occur.
  4. Resolution: a sense of muscular relaxation and general well-being. Men are physiologically refractory to erection and orgasm for a variable period after orgasm, whereas women may respond to further stimulation.
The ICD–10 (World Health Organization, 1992) uses the term ‘sexual dysfunction’ to cover the ways in which an individual is unable to participate in a sexual relationship as he or she would wish. This classification has 10 subdivisions (F52.0–F52.9), each describing different forms of dysfunction. The DSM–IV (American Psychiatric Association, 1994) uses a similar scheme. Whenever possible, doctors should specify which form of sexual dysfunction is present, as these have differing causes and require different treatment approaches.
Some types of dysfunction occur in both men and women, although women tend to present with complaints about the subjective quality of sexual experience (e.g. lack of desire), whereas men often describe the failure of a specific response (such as erection) but a continuing sexual desire.

Epidemiology of sexual dysfunction

This area has not been studied extensively. Nathan (1986) evaluated 22 studies of sexual behaviour in the general population but concluded that methodological problems in the surveys meant that only broad estimates could be made. The prevalence of inhibited sexual desire was 16% for men, 35% for women; for erectile dysfunction and premature ejaculation the prevalence values were 10–20% and 35% of men, respectively; female orgasmic difficulties had a prevalence of 5–15%.
A US study found that sexual dysfunction in the general population is more prevalent in women (43%) than men (31%) (Laumann et al, 1999). Using latent class analysis, symptoms during the previous 12 months could be grouped into three categories. In women, these were low sexual desire (22% prevalence), arousal or excitement problems (14%) and sexual pain (7%); in men, they were premature ejaculation (21%), erectile dysfunction (5%) and low sexual desire (5%).
Reported rates of sexual dysfunction vary considerably, reflecting differences in the study population and types of dysfunction being assessed. Other studies with data for both genders show a higher prevalence of sexual dysfunction in women than in men (Ernst et al, 1993Dunn et al, 1998) and confirm the results for the most common sexual dysfunction in both men and women.
Many factors influence the reported incidence of sexual dysfunction. The first is the method of enquiry. In a prospective study of out-patients with depression, for example, the incidence of sexual dysfunction was 14% when relying on spontaneous reporting. However, this rose to 58% when patients were questioned directly by doctors (Montejo-González et al, 1997). The second factor is that the expectation people have of their sexual performance and their willingness to discuss problems vary between cultures (Bhugra & De Silva, 1993). In the third place, many terms used to define sexual dysfunction are subjective and partly dependent on ideas of what is ‘normal’. Finally, temporal trends can occur as increased awareness of sexual matters and availability of treatment increase the number of those who perceive themselves to be suffering from sexual dysfunction.

Sexual dysfunction in depression

Depression is characterised by loss of interest, reduction in energy, lowered self-esteem and inability to experience pleasure: irritability and social withdrawal may impair the ability to form and maintain intimate relationships. It would be surprising if this constellation of symptoms did not produce difficulties in sexual relationships (Baldwin et al, 1997).
In an early study of 132 patients with depressive disorders, loss of sexual interest (characterised by loss of libido or decrease of sexual desire or potency) was reported by 72% of patients with unipolar disorder and 77% of those with bipolar disorder (Casper et al, 1985). Loss of sexual desire may be the presenting complaint in some patients who are found to have significant depressive symptoms only after direct questioning. In others, low sexual desire may pre-date other features of depression (Schreiner-Engel & Schiavi, 1986).
Comparative studies indicate higher levels of sexual dysfunction in patients with depression than in controls (Table 1). Although the incidence of specific types of sexual dysfunction varies across studies, loss of sexual desire may be more common than disorders of arousal and orgasm. For example, in one comparative study, changes in libido were significantly more common in patients with depression, but the prevalence of impotence, orgasmic or ejaculatory problems did not differ from controls (Mathew & Weinman, 1982). The prospective Zurich cohort study (Ernst et al, 1993) showed that the overall prevalence of sexual problems in subjects with depression (including major depression, dysthymia and recurrent brief depression) was about twice that in controls (50% v. 24%). This difference encompassed emotional problems, sexual dysfunction and both decreased and increased libido. The study findings were from a group of young people (28–35 years old) and are not necessarily applicable to older age groups (Angst, 1998).

Sunday Lecture: Sex Work, Ethics and Human Rights

Conway Hall Ethical Society presents
Sex Work, Ethics and Human Rights - Melissa Gira Grant
The sex industry is an endless source of prurient drama for the mainstream media. Recent years have seen a panic over “online red light districts,” which supposedly seduce vulnerable young women into a life of degradation. But rarely do these fearful, salacious dispatches come from sex workers themselves, and rarely do they deviate from the position that sex workers must be rescued from their condition, and the industry simply abolished—a position common among feminists and conservatives alike.  In Playing the Wh***: The Work of Sex Work ((Verso, 2014), journalist Melissa Gira Grant challenges the myths about selling sex and those who perpetuate them. Arguing for an overhaul in the way we think about sex work, she criticizes both conditions within the sex industry and its criminalization, and argues that separating sex work from the “legitimate” economy only harms those who perform sexual labor. For her, sex work is work, and sex workers’ rights are human rights.

Shahid Khan Afridi First interview with Anwar masood on PTV


Ed Sheeran Shows Off Serious Rapping Skills At U.K. Show: Watch 'I'm the singer that you never want to see shirtless,' he spits on 'Take It Back Now.'

Better watch out Kayne, Drake and Jay, because you have some new hip-hop competition on your hands, and his name is Ed Sheeran.
Yes, Sheeran showed off his (pretty impressive) rapping skills on Tuesday at London's Royal Albert Hall during his Teenage Cancer Trust show. While performing a brand-new track, "Take It Back Now," presumably off his upcoming sophomore album, Ed rapped some verses.
He previously rhymed a little on "You Need Me, I Don't Need You," off his debut album, but clearly he's been working on his technique since then. The British singer rapped at lightning speed at the London show, spitting out imaginative lyrics and delighting his fans.

Over an acoustic beat, Sheeran paints a picture of what his rise to fame has been like, claiming he "didn't listen to any criticism," and thanks his fans for "keeping him going through the tough times." He also revealed some possible insecurities.
"I don't ever want to be perfect because I'm the singer that you never want to see shirtless/ I accept the fact that someone has to win worst-dressed/ Taking my first steps into the scene, giving me focus/ Putting on a brave face like Timothy Dalton/ Considering a name change/ Thinking it was hopeless," he raps as he references the famed "James Bond" actor.
While Sheerios may disagree with the shirtless line and remind him that he was named one of People's Sexiest Men Alive, it seems Sheeran has been more concerned with staying grounded, between the Grammy nominations and super successful tours.
"I'm never having a stylist, giving me tight jeans/ Madison Square Garden is where I might be/ But more likely, uou'll find me in the back room of a dive bar with my mates/ Having a pint with McDaid/ Discussing records we made," he raps referencing friend and Snow Patrol member Johnny McDaid.
The "Give Me Love" singer has been keeping fans guessing on when he'll officially drop new music, but some think it could be next month. Sheeran is slated to perform on "Saturday Night Live" on April 12 and he recently tweeted "7/4/14," which translates to April 7, 2014 Stateside.

Lady Gaga spews forth: This is no act

(CNN) -- After staging a "vomit as art" performance and facing lackluster sales for her latest album, Lady Gaga is ready to speak her piece.
On the "Today" show Friday, the 27-year-old singer defended her commitment to the weird and spectacular (and sometimes the spectacularly weird), explaining that she'd be doing the same outlandish things whether she'd found "The Fame" or not.
"There's a perception that what I'm doing is all a big show, and I really truly feel that it's really just part of who I am. Every moment of my life is devoted to my music and my fans, and it's really, truly me," she said. "I'd just be doing it on the Lower East Side, it'd be the same show, the same act."
That act has appeared to take a stumble. Her newest album, "Artpop," reached No. 1 with just 258,000 copies sold upon its release in November. Her previous album, "Born This Way," notched the same spot in 2011 with 1.1 million copies snapped up in its first week.
Industry observers are quick to note the caveats here: "Born This Way" did have an Amazon.com special attached to it, where fans could buy "Born" for 99 cents for a limited period of time. And compared with other singers with big releases in the fall of 2013, Gaga is still playing in the same league: Katy Perry's "Prism" pushed 286,000 copies in its first week, according to Billboard, while Miley Cyrus' "Bangerz" hit 270,000.
But album sales have become just a slice of Gaga's dwindling perception among an ambivalent public. Her latest effort is a mash-up of high art and pop music that met with mixed reviews from critics who weren't sure what to make of her more avant-garde direction. ("As pop, the album is a well-executed and entertaining tour of Gaga's tried-and-true tricks," Entertainment Weekly said. "But as art, it falls short when it comes to one basic function: making an impression.")
And somewhere along the way, Gaga's usual outrageous behavior -- think meat dresses, arriving at awards shows encased in egg-like structures -- has soured from entertaining to off-putting.
At the South By Southwest music festival last week, Gaga invited "vomit artist" Millie Brown to join her onstage to do what Brown does best: swill brightly colored goos and then regurgitate them in the name of art. So while Gaga sang the "Artpop" track "Swine," Brown participated in the performance by sticking her fingers down her throat and vomiting green and black paint all over the pop star.
Both Brown and Gaga have been accused of everything from crossing a line of general decency to glamorizing eating disorders, which both artists have said was not their intent.
For her part, Brown explained to Elle magazine that she came up with the idea of "vomit art" because she "wanted to use my body to create a performance that was about the beauty from inside out. I came up with the idea of actually vomiting a rainbow using my body as a tool to create paintings. ... My performance is not a statement about eating disorders in any way. I think the whole bulimia thing -- it's important for people to know that I'm not trying to promote it."
And on "Today" on Friday, Gaga stood behind Brown's view of her work.
"(The artist) Millie Brown and I know that not everyone's going to love that performance, but we both really believe in artistic expression and strong identities and I support her and what she does. 'Artpop' is about bringing music and art together in the spirit of creative rebellion, and for us that performance was art in its purest form," the singer said. "(Controversy) doesn't matter. We don't make things for any intention in particular other than in the spirit of entertaining the crowd and really for the moment. It was meant for a club performance in Austin, and it was a great time."
Gaga appeared undaunted by any criticism, explaining that she's charging ahead and at work writing new music. If her appearance at SXSW is any indication, we can expect the singer to continue pointing her arrow more in the same direction.
"I refuse to compromise and allow my talents to be monetized to the point that I don't want to be here anymore," Gaga said during a keynote address at the Texas festival.
"I will stop. I will quit. I will retire from the commercial market if I have to do something other than be myself because if I can't be myself in this moment (then) everything I have said to my friends since the beginning will be a total lie. ... No, I'll be myself till they f***ing close the coffin."

Your nose can smell at least 1 trillion scents

Scientists had long assumed our noses could distinguish about 10,000 odors.
Scientists had long assumed our noses could distinguish about 10,000 odors.

Down at the bottom of the five senses is smell -- at least when it comes to how often we're aware of it.
And while we all know how pungent a bad smell can be, and how memorable a good smell is, we probably don't think our olfactory sense is all that sensitive, at least compared to the rest of our senses -- or to the keen sense of smells exhibited in the animal world (sharks can't literally smell fear, but they can distinguish the smell of fish even if they make up only one part for every 10 billion parts in the water).
While scientists estimate that human beings can discriminate between several million different colors and almost half a million different sounds, they have long assumed that we can distinguish perhaps 10,000 different odors. Most of the time humans are barely aware they're smelling anything at all.


But in reality, our noses are incredibly sensitive -- and a new study publised in Science provides evidence of just how amazing our sniffers are.
Researchers at Rockefeller University and the Howard Hughes Medical Institute (HHMI) tested volunteers' sense of smell using precisely crafted mixtures of odor molecules. After extrapolating the results, the researchers estimated that the average human being can distinguish between 1 trillion different odors, if not more, which makes our noses far more sensitive than any other organ in the body.
"The message here is that we have more sensitivity in our sense of smell than for which we give ourselves credit," said Andreas Keller, a research associate at Rockefeller's Laboratory of Neurogenetics and Behavior and the lead author on the Science study, in a statement. "We just don't pay attention to it and we don't use it in everyday life."
The idea that human beings could only distinguish between 10,000 smells has been around since a 1927 study that posited four elementary odors that people are able to distinguish on a nine-point scale. Do the math and you get 6,651 discernible olfactory sensations, a number that was later rounded up to 10,000.
Although that value was widely cited, most scientists were skeptical -- after all, the human eye uses just three light receptors to see millions of colors, while the typical nose has 400 different olfactory receptors. But as Leslie Vosshall of HHMI and another study co-author noted: "For smell, nobody ever took the time to test."
Obviously the researchers weren't going to try to test each smell individually -- that would take forever. Instead, they used 128 different odorant molecules to create smell mixtures, using 10, 20 and 30 different components. The molecules themselves evoked familiar smells like cut grass, but when combined in random mixtures of as many as 30 different types, the smells became unfamiliar.
That didn't matter -- the study subjects weren't supposed to identify the smells. Instead, the researchers would present them with three vials of scents -- two that were identical, and one that was unique -- and asked them to indicate which scent was different than the others. Each of the 26 subjects made 264 comparisons.
Keller and his colleagues found that their study subjects could generally tell the difference between mixtures containing as much as 51.17% of the same components. Much higher than that, and they were unable to distinguish the smells -- though it's worth noting that some subjects could distinguish between smell mixtures that were as much as 90% similar.
The researchers then extrapolated the total number of mixtures possible in each of their three categories. Since the majority of their study subjects could distinguish between mixtures that were 51.17% similar or less, they estimate that the average human can discriminate more than 1 trillion separate smells.
That is a vast number of scents, and it's almost certainly too low, because there are many more odor molecules in the real world that could be mixed in nearly uncountable ways.
So it's not just that human beings have sensitive olfactory systems -- though not that sensitive, otherwise more people would be able to distinguish smells that were more than 50% similar. It's that the world offers a near infinite variety of smells.
If human beings think their sense of smell isn't that important, it has more to do with the fact that we've done our best to eliminate smells through refrigeration, air filtration, and yes, daily showers. As Vosshall put it:
"The world is always changing. Plants are evolving new smells. Perfume companies are making new scents. You might move to some part of the world where you've never encountered the fruits and vegetables and flowers that grow there. But your nose is ready. With a sensory system that is that complex, we are fully ready for anything."

The nose, as it turns out, really does know.
