Wanna be happy? Have some ice cream







Ice cream’s great, people have known it for years. And, now a new study has also confirmed it — a spoonful of the cold stuff really makes everyone happy. Researchers at Ashland University in Ohio have based their findings on an analysis of food choices of 240 young adults who were asked to rate a list of 62 stuff on happiness, excitability, pleasantness, and comfort. Ice cream got the highest happiness scores followed by chocolate, cake, grapes, and pizza. While those on the lowest happiness scores included tofu, soy, avocado and bologna, the WebMD reported. The subjects also rated each food's healthiness. “Healthiness scores indicated that the lowest ranked foods primarily consisted of snack food items, where the highest were certain fruits and vegetables (broccoli, apple, orange, carrots, grapes, and peach),” lead researcher David Vanata said. The researchers also gave the participants a pop quiz after they finished ranking the foods. The task: Flip the page over and quickly write down as many of the listed foods as they could remember. The participants recalled significantly more of the healthy foods than the unhealthy foods.But they weren’t particularly likely to recall the foods with high emotional scores, either in terms of the foods’ overall emotional response or happiness, excitability, pleasantness and comfort. “Emotional words were not recalled more than non-emotional words and healthy foods were recalled over unhealthy foods,” Vanata said.

All about India's moon mission

October 17, 2008

AIndia's first Moon mission, Chandrayaan is all set to add a golden chapter to India's space endeavour when it takes off from the Satish Dhawan Space Centre at Sriharikota on October 22.

Here's all that you wanted to know about India's first Moon mission

  • What is Chandrayaan-1?

    Chandrayaan-1 is a scientific investigation -- by spacecraft -- of the Moon. The name Chandrayaan means Chandra (Moon), Yaan (vehicle). Chandrayaan-1 is the first Indian planetary science and exploration mission.

  • When, and from where, Chandrayaan-1 will be launched?

    Chandrayaan-1 will be launched on October 22, 2008 from Satish Dhawan Space Centre at Sriharikota (SHAR).

  • How long will it take Chandrayaan-1 to get to Moon?

    It will take about 5� days for Chandrayaan-1 to get to the Moon.

  • How close to Moon will Chandrayaan-1 come while orbiting the Moon?

    Chandrayaan-1 spacecraft will be in a 100 km polar orbit around the Moon.

  • What are Chandrayaan' s scientific goals?
  • The Chandrayaan-1 mission is aimed at high-resolution remote sensing of the Lunar surface in visible, near Infrared, low energy X-rays and high-energy X-ray regions.

    Specific scientific goals are:

    • To prepare a three-dimensional atlas (with a high spatial and altitude resolution of 5-10m) of both near and far side of the moon.

    • To conduct chemical and mineralogical mapping of the entire lunar surface for distribution of elements such as Magnesium, Aluminum, Silicon, Calcium, Iron and Titanium with a spatial resolution of about 20 km and high atomic number elements such as Radon, Uranium & Thorium with a spatial resolution of about 40 km.

    By simultaneous photo geological and chemical mapping we will be able to identify different geological units, which will test the hypothesis for the origin and early evolutionary history of the moon and help in determining the nature of the lunar crust.

    Delta 32 Mutation

    There may be. There are many stories where someone who was in constant contact with plague victims didn’t die. Maybe genetics is the explanation.

    For example, in 1665, the plague hit a small village in England called Eyam. The town quarantined itself to keep the Black Death from spreading into the rest of the country. A year later, the plague had burnt itself out but half of the townspeople were dead. Was there something special about the half that lived?

    In 1996, researchers tracked down descendants of the people of Eyam and looked for any mutations they might have in common to explain this high survival rate. What they found was a mutation called CCR5-delta 32. 

    The CCR5-delta 32 mutation was already known for a different reason—people with one copy of the CCR5-delta 32 mutation are resistant to HIV, the virus that causes AIDS. People with 2 copies are virtually immune to HIV. 


    The spread of the black death


    The CCR5-delta 32 mutation probably arose a few thousand years ago in Northeastern Europe. It stayed rare until around 700 years ago when it suddenly became more common. The plague started in Europe around 700 years ago.

    So, does CCR5-delta 32 protect people from the plague bacteria? Probably not. Mice infected with the plague bacteria died at around the same rates whether or not they had the CCR5-delta 32 mutation. 

    Why then is this mutation so common in Europeans and even more common in people whose ancestors came from Eyam? 

    Maybe smallpox is the reason. Smallpox killed 3 in 10 infected people for thousands of years in Europe. Recent studies suggest that smallpox, like HIV, can’t infect someone with the CCR5-delta 32 mutation.

    Of course this doesn’t explain Eyam (unless there was a lot of smallpox in the area). A more controversial theory is that an unknown virus, not the plague bacteria, caused the Black Death. Besides the evidence of the CCR5-delta 32 mutation itself, some people contend that the disease shouldn’t have been stopped by quarantine and that it spread too quickly for a flea borne illness. 

    Anyway, as you can see, while genetics were probably involved, there isn’t yet a solid answer as to what genes were involved.

    "KHWAISHEIN"

    Dear Friends, 
     
    ~ANEEK'S MOST AWAITED ALBUM RELEASE ~
                                       "KHWAISHEIN"
    Fans of Aneek Dhar have been spellbound by his remarkable singing since his entry on the music scene. He first gained a reputation for good singing when he won the Bengali spin off of the popular Zee TV talent hunt Sa Re Ga Ma Pa. The format of that competition required that performances in the show�s finale will also be scored and the winner would be chosen at the end of the show. So, after hours of competition on the show�s finale, and after months of hard work, Aneek became the winner. Aneek appeared as a wild card entry in Zee TV�s Sa Re Ga Ma Pa Challenge 2007.
     
    This competition was an international one, gathering talent from all over the globe in one talent search. One of his performances was so touching that it brought tears to a judge�s eyes. Judges of the Sa Re Ga Ma Pa competition had wonderful things to say about Aneek. Shekhar Ravjiani (of music director duo Vishal-Shekhar) called Aneek a �ready made playback singer.� Ghazal maestro Jagjit Singh commented �you sing very well. At your age, we used to struggle but you did a fabulous job.� After months of tough competition Aneek was declared the winner on October 13th 2007.

    His fans have watched Aneek sing songs from all genres of Indian music with equal ease and comfort. And now, he has come out with his first album! Aneek Dhar's album "KHWAISHEIN" will be releasing in September. The album has great potential. Its tracks will be enjoyed by all his fans. Many prestigious music directors have contributed to the making of this album. I encourage all fans to own original copies of this album to support our favorite singer�s first solo musical venture.
    (Write up by my dear sis Sonnia@Lucky Jade)

    The grand release will held at two places.It will be in Kolkata and on the set of Srgmp(Bombay) in September 2008. The Kolkata launching of the album will be held on September 12th. The taping of his SRGMP launching is complete and it should be telecasted this week. You can click on the link below for a picture slide show of the SRGMP launching. (Courtesy of Bollyvista)
