Facial Symmetry And Good Gene
Do you know that “beautiful people are healthier and live longer”? One of many researches performed at McMaster University, Canada, reports that symmetrical faces regarded as being more attractive. It also an indicator of good genes, great health conditions and long life.
It’s been suggested that symmetrical faces are indicators of a good “mate” , and these mates have good genes which can be inherited by the next generation.
Cat’s Urine And Machoism In Rats
Researcher had expected that the smell of a cat would reduce the sexual drive in rats and the scared mice aren’t sexy mice. But now they have found that cats could help mice get lucky in love.
According to a new study cat’s urine not only scare mice away, but it also seems to act like an aphrodisiac (agent that arouses sexual desire) for the rats. The smell make male mice more macho and attract females.

Doomsday Is 2012
As we all know, there are many spiritual leaders and believers had predicted end of the world, dating back to at least 2800 B.C. They have all been wrong for thousands of years, but they are still trying to predict the doomsday.
These believers solely trust that they have known the Earth- shaking secret that should be informed to others. We all are familiar with the dozens of predictions that the world would end in 2000, but it’s been 8 years and nothing happened so far.
The latest prediction says that the world is going to end in 2012 . It either will bring a new age of global spiritual awakening, or the end of the world. Or maybe something in between.

Do Birds Know If You Look In The Eye?
The eyes are the window to the soul. Eyes can tell us one’s emotions and intentions. According to a research done by Julia Carter and her colleagues from University of Bristol, Starlings keep away from their food dish if a human is looking at it. When the person is just as close, but if their eyes are turned away, the Starlings started feeding earlier and consumed more food.

How Many Items Can You Remember?
Researchers have found out that the maximum amount of items we can store in our conscious mind is only three to four at a time. This is what’s called our working memory. It is more active version of short-term memory, which refers to the temporary storage of information. Scientists also suggested that the true capacity is lower when people are not allowed to use tricks like repeating items over and over or grouping items together.

How Do Birds Navigate?
Animal species, ranging from birds and mammals to reptiles and insects, navigate by using the Earth’s magnetic field. But Earth’s magnetic field is very weak. So how exactly birds do it. New research finds that a photochemical compass helps migrating birds to use the magnetic field along with light. The photoreceptors in a bird’s retina absorb light, which then produces a short-lived photochemical substance that is sensitive to the magnitude and direction of a weak magnetic field. It’s been supported by the fact that blue light photoreceptors have been detected in retinas of migratory birds when they perform magnetic orientation.

Scaning The Genome For Disease
Exploring the genetic background of major diseases such as diabetes or cardiovascular diseases has now become easier. Normally DNA sequence of every organism shows natural variations called “single nucleotide polymorphisms” or SNPs. The genome of an individual has several million SNPs and, which will be different from others within the same species. Now scientists investigate these SNPs to clarify whether they are related to or influence the development of certain diseases. Researchers have now discovered three million SNPs in the genome of the rat, which will help to understand the background of major diseases.

NASA Launches New Science Web Site
A new Web site has been launched by NASA’s Science Mission Directorate, which provides enhanced and engaging information about NASA’s vast scope of scientific endeavors and achievements. The site will provide in-depth coverage of NASA’s past, present and future science missions with features that include:- Interactive tables and searches for Earth, heliophysics, planetary and astrophysics missions
- Resources for researchers including links to upcoming science solicitations and opportunities
- A citizen-scientist page with access to resources that equip the public to engage in scientific investigation
- Expanded “For Educators” and “For Kids” pages to provide access to a broader range of resources for learning the science behind NASA missions
- Easy-to-navigate design and an improved search engine to help find information.

Soyuz Landed 400km Off-target because of women?
The Russian Soyuz re-entry capsule, carrying the first South Korean astronaut back to Earth, suffered a “ballistic re-entry”, putting the capsule 400 km (250 miles) off-target. Russian Federal Space Agency chief Anatoly Perminov placed some of the blame on an old naval superstition.
“.. in the future, we will work somehow to ensure that the number of women will not surpass [the number of men].”

Good Rhythm And Intelligence
Researchers at the medical university Karolinska Institutet and Umeå University of Sweden, demonstrated a correlation between general intelligence and the ability to tap out a simple regular rhythm. But the task subjects performed had nothing to do with any musical rhythmic sense but simply measured the capacity for rhythmic accuracy. The study also revealed a correlation between high intelligence, a good ability to keep time, and a high volume of white matter in the parts of the brain’s frontal lobes involved in problem solving, planning and managing time.
High Definition moon map
Japan’s lunar spacecraft,Selene is sending stunningly-detailed information from Moon. JAXA—Japan’s space agency—also announced that the Selene mission has gathered detailed information regarding the mineral composition of parts of the Moon’s surface, including thorium, potassium, and uranium sites.
Soyuz takes South Korea’s first Astronaut
So-Yeon Yi, a 29-year-old female engineer, is flying under a commercial agreement between the Russian space agency and South Korea’s ministry of science and technology. Yi will spend nine days aboard the space station and return to Earth on April 19. She is the youngest woman to ever launch into space.
