Favourite Foods Determined by Mother's Milk

Scientists have found that children's food preferences depend on the flavours passed to them through their mothers milk.

Dr. Beauchamp of the Monell Chemical Senses Center in philadelphia, found that children who had been fed savoury milk preferred savoury tastes, where as those with sweet milk preferred sweeter tastes.

The critical time in which babies learnt this preference was at the age of two to five months. It is believed that if mothers eat healthy foods such as fruit and vegetables at this critical time, babies can be primed to like it later in life. Mothers are therefore to be advised to increase consumption of healthy products during this time.

This means that babies who are fed formula milk instead of breast milk do not get this priming, and do not get the varied sensory stimuli that they would be exposed to with breast milk.

Glass half full genetics

Scientists at the University of Michigan have discovered that people optimistic or pessimistic outlook to life is genetic, and depends on levels of just one molecule: Neuropeptide Y.

They found that if you have lower levels of NPY, you are likely to be more pessimistic than those with higher levels. This in turn means that people with lower NPY are more likely to have depression and react badly to stressful situations.

The scientists made this finding by scanning peoples brains while showing them neutral and emotionally charged photos. Those with high NPY had a stronger emotional response to the photos than those with lower levels. This means that people may be diagnosed earlier with psychiatric conditions such as depression.

Wear Blue to Prevent Shark Attack

Researchers have found that sharks are colour blind. They can only distinguish between light and dark areas. This has lead researchers to conclude that swimmers who wear blue wetsuits are less likely to be attacked as the sharks could not distinguish between them and the surrounding sea.

Statistics shows that people attacked by sharks usually are wearing black wetsuits, backing up this claim.

This information means that surfing equipment and swim wear will be able to be designed to be essentially invisible to sharks. I could also be used when designing fishing lures, to prevent sharks from being caught.

Bullet-Proof Custard

A new type of body armour, dubbed "bullet-proof custard" has been developed for the army.

The armour contains a custard like substance embedded between layers of kevlar. The substance is compared to custard as it hardens when it is impacted. It means the armour is more flexible than traditional designs but even more effective at preventing damage from bullets.

The armour is half the weight as traditional designs, allowing soldiers more maneuverability, and to stay cooler under extreme conditions.

'Toylet': Gaming While You Go!

Sega have invented a new gaming system that you play while you are in the bathroom, and the controller is your wee!

The device, named the 'Toylet', has sensors that can pick up the speed, location and intensity of urine as it enters the urinal. There are currently a choice of four games that you can play. 

The consoles are going to be installed in four metro stations in Japan. The screens will show adverts as well as the games in order to make money from the consoles.

The Latest in the Fight Against Pirates: Laser Canons!

Laser canons have been developed by engineers to defends ships from pirates. The idea is that it is a non-leathel weapon that dazzles and confuses pirates so they are unable to approach the ship.

The lasers are capable of working up to a mile away, they cause a green glare that is able to hide the ship preventing the pirates from aiming weapons or approaching the ship.

The laser is able to work with radar so they can automatically fire at targets. It also has the capability to fire at a rapid rate to produce flickering which intensifies the effect.
