Shopping malls set to be replicated in e-world




Shopping online is easier than shopping in a mall — as long as you know exactly what you want to buy. The problem comes when you don't know what you want.

The web has yet to duplicate the real-world feel of a mall. But now, many entrepreneurs have their sights set on better replicating those experiences online, creating a category of e-commerce loosely known as social shopping. Venture capitalists are opening their pocketbooks for these new start-ups , and even some of the biggest players in e-commerce , like Amazon and eBay, have introduced their own social features.

The social shopping sites essentially compile stylish goods of similar sensibility from shops around the Web, and make it easy to share with friends what items they like and buy. Most of the sites have adopted the interface of pinning images on a virtual bulletin board popularized by Pinterest , one of the most popular social networks.

Deena Varshavskaya, the founder and chief executive of the social shopping site Wanelo , which she started in late 2010, said sites like Amazon, eBay and Etsy had made people comfortable with buying things online. But as more companies and shops migrated to web, it became harder to find cool, stylish and quirky items, giving entrepreneurs an opening.

comment ;- i like to shop in an e shopping mall ,where i can see each item on display in "x' or "y" mall will be seen on screen  in the same exact order as in the real mall.i like to browse through each SUCH mall and select and E- buy ,instead of driving around and wasting time ,from mall to mall 

Too many soft drinks make child aggressive


MUMBAI: Young children who have more than four soft drinks a day are twice as likely to destroy things belonging to others, get into fights and physically attack people.

This is the conclusion of a new research by Columbia University's Mailman School of Public Health that has been published in The Journal of Pediatrics. Stating that Americans buy more soft drinks per capita than people in any other countries, the study said that aggression, attention problems, and withdrawal behavior are all associated with soft drink consumption in young children.

Shakira Suglia and colleagues assessed approximately 3,000 5-year-old children enrolled in the Fragile Families and Child Wellbeing Study, a study that follows mother-child pairs from 20 large US cities. Mothers reported their child's soft drink consumption and completed the child behavior checklist based on their child's behavior during the previous two months. The researchers found that 43% of the children consumed at least 1 serving of soft drinks per day, and 4% consumed 4 or more.

Aggression, withdrawal, and attention problems were associated with soda consumption. ``Children who drank 4 or more soft drinks per day were more than twice as likely to destroy things belonging to others, get into fights, and physically attack people,'' said the study. They also had increased attention problems and withdrawal behavior compared with those who did not consume soft drinks.

"We found that the child's aggressive behavior score increased with every increase in soft drinks servings per day," said Dr Suglia.

Decoded: How females choose the right sperm

WASHINGTON: Scientists have decoded how females select the 'right' sperm to fertilize their eggs when faced with the risk of being fertilized by sperm from a different species.

Researchers from the University of East Anglia investigated salmon and trout, which fertilize externally in river water. Since hybrid offspring of the two species become reproductive deadends , females of both species practice selection to avoid hybrid fertilizations.

The study shows that when eggs from each species are presented with either salmon or trout, they happily allow complete fertilization by either species' sperm. However, if eggs are given a simultaneous choice of both species' sperms, they clearly favour their own species' sperm.

"It is actually the ovarian fluid that controls which species' sperm wins the fertilizations... If we put salmon ovarian fluid onto salmon eggs, then salmon sperm win, but if we put trout ovarian fluid onto eggs from that same salmon female, trout sperm now win," researchers said.

"Ovarian fluid gives a chemical signal to the sperm of its own species, causing changes in the way their tails beat, so that they swim in a straighter trajectory, and therefore guided more effectively towards the site of fertilization. These findings allow us to establish that females have indeed evolved mechanisms of 'cryptic choice' at the level of the sperm and egg," said researchers.
