Science & Technology Facts

Astronomers found a twin star to Earth’s own sun, which is much older. The rare star is the oldest known solar twin and can tell what Earth star will looks like in 4 billion years. The star, called HIP 102152, appears to be as similar to the Sun in its basic characteristics as any other known star. The sun is only 4.6 billion years old; HIP 102152 is 8.2 billion years old.

Acer on 2 September 2013 launched a new Smartphone with a 6-inch screen called the Liquid S2 which is the world’s first 4K recording Smartphone which is four times the resolution of current full HD. 4K video will be shot using the phone’s 13 megapixel rear camera and the power of a quadcore Qualcomm Snapdragon 800 processor which is clocked at a stunning 2.2GHz.

A new scientific study showed that ageing works through a special set of genes that everyone has, the rDNA genes. The international team led by Dr Takehiko Kobayashi from the National Institute of Genetics in Mishima, Japan, found that if we improve the stability of the rDNA genes, which are quite unstable, the lifespan of baker’s yeast could be extended. It could help in studying cell ageing.

Scientists have discovered that the sleeping patterns of baby owls are similar to that of human babies. The sleep of baby birds appears to change in the same way as it does in humans, researchers at Germany’s Max Planck Institute for Ornithology and the University of Lausanne in Switzerland have found.

An Indian-origin designer has developed “smart” street lamps, which light up only in the presence of people or vehicles. The invention could slash energy costs by 80 per cent. Chintan Shah invented the system dubbed Twilight when he was a student at the Delft University of Technology in the Netherlands. The lamps have sensors that can distinguish between people and small animals like cats and mice, to avoid lighting up unnecessarily.
