    World AIDS Day: Is the end of AIDS in sight? 10 facts about HIV/AIDS

    World AIDS Day on December 1 is used to unite people in the fight against HIV, the human immunodeficiency virus first identified in 1984, to show their support for people living with HIV and commemorate those who have died. Here are some facts about AIDS in 2015 with data from the World Health Organisation, the United Nations children's agency UNICEF, and UNAIDS

    1. Globally about 36.9 million people are living with HIV including 2.6 million children.


    2. An estimated 2 million were infected in 2014.

    3. An estimated 34 million people have died from HIV or AIDS, including 1.2 million in 2014.

    4. The number of adolescent deaths from AIDS has tripled over the last 15 years.

    5. AIDS is the number one cause of death among adolescents in Africa and the second among adolescents globally.



    6. In sub-Saharan Africa, the region with the highest prevalence, girls account for 7 in 10 new infections among those aged 15-19.

    7. At start of 2015, 15 million people were receiving antiretroviral therapy compared to 1 million in 2001



    8. Despite widespread availability of HIV testing, only an estimated 51 percent of people with HIV know their status.

    9. The global response to HIV has averted 30 million new HIV infections and nearly 8 million deaths since 2000.

    10. In 2015, Cuba was the first country declared to have eliminated mother-to-child transmission of HIV.

    What giving up sugar, alcohol can do for you in just one month


    A man has attempted to live without alcohol and sugar for a month to see what impact it would have on his health.

    The film, from Dutch online television channel, Lifehunters, follows a volunteer as he goes for 30 days without the two treats.

    Although Sacha, 22, loses 8lb in weight, sees his blood pressure fall from 135 to 125 and gets his cholesterol to drop eight per cent, the fasting period proves far from easy.

    After just one week, he reports feeling "cranky" and constantly hungry.

    "Sugar wants vitamins," a nutritional expert tells him. "It makes you feel tired. Alcohol does that too. You dehydrate.

    "You will feel fitter after a month without sweets, alcohol and preserved foods."

    Food containing added sugar is everywhere, he finds, including places you might not expect.

    A carton of iced tea contains 10 lumps, a bowl of tomato soup five lumps, and a stir fry sauce for two has a massive 15 lumps of sugar.

    The fasting host is forced to live off fruit, yoghurt and salads. But after three weeks he finds his cravings start to diminish and he has much more energy.

    The 22-year-old told the Daily Mail that one of the most interesting impacts of the challenge was when he started eating sugar again. "I got arrhythmia twice in one and half weeks when I started eating sugar again," he said. "I also had trouble sleeping; I couldn't fall asleep before 3am or 4am. [My body] wasn't used to sugar any more and it came in like a drug.'

    Sugar has range of ill-effects on the body including obesity, heart disease, diabetes, tooth decay and possible cancer, according to experts.

    The World Health Organisation recommends that we get just 5% of our daily calorie intake from sugar.

    But the National Diet and Nutrition survey has found that sugar intake in the UK is much higher with adults getting 12.1% of their calories from sugar.

    And teenagers are the worst offenders with 11-18 year-olds obtaining 15.6% of their calorie intake from the sweet stuff.

    Experts advise that cutting down on sugar can lower your chances of getting type-II diabetes, heart disease and other diseases linked with being overweight.

    Five startling facts about 'death'!


    What is that one undying fear in your life? Death is the answer. Whether you like it or not, the fact remains that we all have to face this 'dread' in our lives.

    Just like change is inevitable, so is death. Whoever is born has to go one fine day to a better world. There is a lot of curiosity which makes us wonder what actually death is all about.

    Today, let's take a look at some facts related to death:


    • It is a known fact that for at least 200,000 years, humans have been burying the dead bodies.
    • We are still confused as to why we get old and die at the end. However, there is one theory which implies that some creatures are killed or die of disease before they can get old.
    • Some of the leading causes of death worldwide are heart diseases, accident or deaths during childbirth.
    • Have you ever wondered what happens to our brain after we die? Well, brain cells too die after few minutes of the heart stopping. Even skin cells survive up to 24 hours.
    • We have always seen that dead bodies usually swell up like balloons after about four days. But do you know why? Swelling of body is manily due to the gases and liquids released by autolysis.

    How marijuana use leads to severe mental disorder

    Cannabis or marijuana use increases neural noise in the brain, leading to a severe mental disorder in which thought and emotions are so impaired that contact is lost with external reality, says an Indian-origin researcher.

    The team from Yale University found that a primary active constituent of cannabis induces transient psychosis-like effects in healthy participants similar to those observed in schizophrenia.

    “At doses roughly equivalent to half or a single joint, the compound called '?9-THC' produced psychosis-like effects and increased neural noise in humans,” explained senior author Dr Deepak Cyril D'Souza, professor of psychiatry.

    The findings suggest that increased neural noise may play a role in the psychosis-like effects of cannabis.

    The investigators studied the effects of “?9-THC” on electrical brain activity in 24 human subjects who participated in a three-day study.

    If confirmed, the link between neural noise and psychosis could shed light on the biology of some of the symptoms associated with schizophrenia.

    “This interesting study suggests a commonality between the effects on the brain of the major active ingredient in marijuana and symptoms of schizophrenia,” stated Dr John Krystal, editor of the journal Biological Psychiatry that published the paper.

    Three-four cups of coffee can cut diabetes risk

    Much to coffee lovers' delight, drinking three to four cups of coffee per day can reduce the risk of developing Type 2 diabetes, said a new study.

    Danish scientists have identified two compounds that contribute to this health benefit, adding that this knowledge can help them develop new medications to better prevent and treat the disease.

    To investigate which of coffee's many bioactive components are responsible for diabetes prevention, the team tested the effects of different coffee substances in rat cell lines.

    The researchers investigated different coffee compounds' effects on cells in the lab.

    The two compounds - cafestol and caffeic acid - increased insulin secretion when glucose was added.

    The team also found that cafestol increased glucose uptake in muscle cells, matching the levels of a currently prescribed antidiabetic drug.

    According to lead researcher Soren Gregersen from Aarhus University Hospital in Denmark, cafestol's dual benefits make it a good candidate for the prevention and treatment of Type 2 diabetes.

    However, because coffee filters eliminate much of the cafestol in drip coffee, it is likely that other compounds also contribute to these health benefits.

    Patients with Type 2 diabetes become resistant to insulin, a hormone that helps turn glucose from food into energy.

    To overcome this resistance, the pancreas makes more insulin, but eventually, it just can't make enough.

    High blood glucose levels can cause health problems, such as blindness and nerve damage.

    Several genetic and life style risk factors have been linked to the development of Type 2 diabetes, but drinking coffee has been shown to help prevent its onset.

    The paper was reported in ACS' Journal of Natural Products.

    People who watch violent films more likely to lie, cheat

    Love watching movies with violent content? You may be more likely to lie, cheat or steal, according to a new study which found that exposure to violence could make people less ethical. The study found that exposure to human violence is strongly linked to an increase in cheating for monetary gain.

    Josh Gubler, professor at Brigham Young University (BYU) in US, and David Wood, professor at the Marriott School of Management at BYU, carried out three experiments with roughly 1,000 participants for the study. In the first experiment, participants were paid to review sentences and edit those with mistakes. Half of the participants were given sentences with violent language.

    Subjects were told they would be paid whether or not they were correct, providing an incentive to mark all sentences "correct" to earn money quicker. Those who reviewed violent sentences were 24% more likely to cheat.

    In another experiment, participants were hired to watch and evaluate movie clips. They were told they needed to watch the entirety of all the clips to be paid.

    One clip consisted of 10 minutes of a blue screen with a monotone voice over. The researchers found those who viewed violent movie clips were more likely to lie about watching all the videos. While both male and female test subjects responded to violently worded media, only the men's ethics were negatively influenced by violent videos.

    Now, super strong dental fillings that don’t corrode

    Graphene oxide could be used to make non-toxic, super strong dental fillings that do not corrode, researchers have found.

    Fillings are typically made of a mixture of metals, such as copper, mercury, silver and tin, or composites of powdered glass and ceramic. Typical metal fillings can corrode and composite fillings are not very strong. Graphene on the other hand is 200 times stronger than steel and does not corrode, making it a prime new candidate for dental fillings, the researchers said.

    "We believe that this research will bring new knowledge about the cytotoxic properties of graphene-based materials and their potential applications in dental materials," Adriana Filip, associate professor at Iuliu Hatieganu University of Medicine and Pharmacy in Romania said.

    The next step for this research is for the team to make dental materials with graphene oxide and test how compatible they are with teeth, and how toxic they are to cells.

    Balloon Kyphoplasty technology can help treat vertebral fractures: Experts

    If you are among those who close their eyes to back pain simply as outcome of overwork, this may give you a reason to think otherwise. According to scientific research, chronic back pain, which is often mistaken as fatigue, is strongly associated with vertebral fractures, leading to functional loss, disability, poor quality of life and osteoporotic compression fractures affects millions of people globally. Known to cause more than 8.9 million fractures annually, osteoporosis is a generalized skeletal disorder of low bone mass (thinning of the bone) and deterioration in its architecture. With the rise in the number of youngsters leading sedentary lifestyles, poor eating habits and using tobacco, osteoporosis is no longer a disease of the aging population.

    According to experts, it's not just weakening bones, but another very important aspect of osteoporosis - the "silent" vertebral fractures - that produce no obvious symptoms to the patient in its early stages. As per research studies, approximately 30-50 percent of women and 20-30 percent of men develop vertebral fractures and half of them develop multiple fractures during their lifetimes, compared with a 15.6 per cent lifetime risk of a hip fracture.

    According to experts, Balloon Kyphoplasty is one such technology which can easily help treat vertebral fractures without too many complications. For working professionals, it is the best option as it entails only a short stay in the hospital, faster recovery, minute scars and very little blood loss. Explains Dr. Soumyajit Basu, Sr Spine Surgeon, Park Clinic, "Balloon kyphoplasty is a minimally invasive surgery technique. In a minimally invasive surgery, a small incision is made to get to the problem area which ensures low levels of trauma to the tissues, tiny incision, and better blood supply to the operated area. Earlier, only extensive procedures were available to treat vertebral compression. This would typically require the patient to stay for a long period of time in the hospital, while experiencing delayed recovery and other complications. Balloon kyphoplasty, which restores the compressed spine and stabilizes the fracture, is a safe option for patients."

    Puzzle behind face blindness solved?


    The causes of congenital face blindness -a condition in which a person s unable to use facial features to identify other people -can be traced back to an early stage in the perceptual process, scientists say. Each face is unique and forms a crucial part of a person's identity and interpersonal communication, researchers said.

    Researchers focused their efforts on a group of persons who have experienced problems recognising familiar faces from a young age, but show no evidence of other cognitive impairments. "We were able to show that even the earliest face-selective responses, those recorded approximately 170 milliseconds after seeing a face, are altered n people with congenital prosopagnosia; we were also able to show that these changes are linked to their deficit in recognising aces," said researchers, who used magne oencephalography to measure the magne ic signature of cortical activity.

    Gymming may be turning you into a boozer

    Exercise and drinking are usually thought to be two separate things, one healthy, the other unhealthy, but according to science, they actually go together very well.

    The Pennsylvania State University researchers noticed a direct link between when people exercised and when they had an alcoholic drink, the Daily Express reported.

    Regardless of the time of year, exercise directly influenced the amount people drank and when they had alcohol.

    When participants engaged in more physical activity than usual, their alcoholic consumption went up.

    Researchers found people wanted to extend the feel-good feeling of exercise This link between exercise and drinking didn't indicate heavy drinking, though and that, people stuck to a primarily moderate intake, rarely engaging in a heavy drinking session.

    Researchers then conducted a second study to find out exactly why exercise causes us to drink and revealed that it's because people want to extend that post-gym feel-good feeling.

    It also seems like exercise goes hand-in-hand with getting boozy, as another reason researchers gave for why people are prone to drinking alcohol after exercise was related to the social aspect of sport and fitness.
