Breastfeeding helps mothers stay slim

Breastfeeding has long been believed to help mothers get their figure back after giving birth. Now, a new study has claimed it could also help them stay slim for decades.
Researchers at the Oxford University found that women who breastfed their babies even for a few months after the birth were less likely to be obese 30 years later.

The researchers worked out that for every six months a woman gives her baby breast milk, she loses around two pounds, depending on her initial weight and height.Although this may not sound much, the researchers claimed it could help prevent thousands of deaths from cancer, heart problems and other illnesses related to obesity, the Daily Mail reported.

The study, published in the International Journal of Obesity, surveyed 740,600 women whose average age was 57. They had all answered questions about how many children they had and the total number of months they had spent breastfeeding.

Experts have already established that breastfeeding uses up large amounts of energy which is equivalent to burning 500 calories a day — the same as a typical gym session.

Wallpapers to light up rooms

A Pakistani scientist has succeeded in growing white LEDs directly on paper.  With this breakthrough, people can now imagine a white luminous curtain waving in the breeze or wallpaper that lights up your room with perfect white light.

Gul Amin, who recently received his doctorate at the Physical Electronics and Nanotechnology group, Campus Norrkoping, showed in his thesis how it is possible to grow white LEDs, made from zinc oxide and a conducting polymer, directly on a piece of paper. He also described how they could be printed onto wallpaper, for example - a method with a patent pending.

His research colleague, Naved ul Hassan Alvi, looked at his thesis from last summer at various methods for producing - growing - different nanostructures of zinc oxide on a number of different semiconducting materials.

Nanostructures of zinc oxide have a number of characteristics that make them suited to the manufacture of white LEDs - among them a large band gap and electrons that move easily and give off relatively large amounts of energy once they have bounced back towards the nucleus.


Common barnyard chicken may help fight cancer

The common barnyard chicken could provide some very un-common clues for fighting off diseases and might even offer new ways to attack cancer, a team of international researchers has claimed.  James Womack from Texas A and M University and the team, comprised mostly of scientists from the Seoul National University in Korea, examined 62 White Leghorn and 53 Cornish chickens for diversity in NK-lysin, an antibacterial substance that occurs naturally in animals and is used as a method of fighting off diseases.

They were able to obtain two genetic variations of NK-lysin and the results offered two unexpected shockers: both showed abilities to fight off bacterial infections and other diseases, while one showed it could successfully fight cancer cells as well.
“It took all of us by surprise,” Womack said.
