SCI-ZONE

By Dr. Freak

Food Packaging Gets Hi-tech
Ever got fooled by the charismatic salesman and bought some ancient and expired pack of food, only to find it totally inedible afterwards? Well, that is coming to an end as food packages are getting smarter. Later this year, you may witness the introduction of hi-tech food-cartons, which can monitor freshness, temperature and moisture while dramatically increasing shelf-life. Swedish dairy giant Arla Foods developed this special sensory packaging system which accommodates electronic identifiers. These cartons can also communicate with smart, computer-controlled refrigerators. Well, it looks like digital technology is going to change our life a lot in the coming days. Sci-fi life is becoming reality.

Hawking Changing His Black Hole Theory
Stephen Hawking, regarded as the greatest living scientist of our age, has finally changed his revolutionary Black Hole theory after 30 years. He announced the fault of his theory in the 17th International Conference on General Relativity and Gravitation. Hawking admitted that his speculation about black holes swallowing up all that comes near it is contradictory and he has finally concluded that not all information is lost after a matter gets into a black hole. Though he is yet to publish any details, the scientific community is quite buzzing about Hawking's new theory. Sorry sci-fi enthusiasts, black holes are not a passage to another world.

Japanese Carrier Unveils Mobile-Phone Wallet
Ever got frustrated with countless notes and coins and calculation of changes you get back? In this world of cashless payment, we Bangladeshi's are definitely living in the stone age as only a few of us have access to credit cards. Well, in Japan, credit cards are also ancient, as their mobile phones are becoming the money-wallet. Japanese mobile-service giant NTT DoCoMo has unveiled a new transaction system, which enables the user to use the cell-phone to pay all the bills. A small microchip incorporated in the phone does the trick. All you have to do is find out the electronic payment counter, find out bill and balance and simply wave your cell phone within a few inches of a special display found in stores, restaurants and vending machines around Japan. A fairy-like tinkling sound means your purchase is being deducted from the embedded chip using radio-frequency ID technology. Sounds good? Well as for us, we may get a hold on this technology soon (as in our country, very soon means waiting about a decade).

Want To Eat? Pee On It
Would you eat food cooked in your own urine? If not, you are in serious trouble if you are lost in the desert with few rations. You may think its insane, but the US Army don't. Food scientists working for the US military have developed a dried food ration that troops can hydrate by adding the filthiest of muddy swamp water or even peeing on it.The ration comes in a pouch containing a filter that removes 99.9 per cent of bacteria and most toxic chemicals from the water used to rehydrate it, according to the Combat Feeding Directorate, part of the US Army Soldier Systems Center in Natick, Massachusetts. This is the same organisation that created the "indestructible sandwich" that will stay fresh for three years. The aim is to reduce the amount of water soldiers need to carry. One day's food supply of three meals, weighs 3.5 kilograms but that can be reduced to about 0.4 kilograms with the dehydrated pouches, says spokeswoman Diane Wood. The pouch - containing chicken and rice initially - relies on osmosis to filter the water or urine. Well, it's a definite step in fighting the food crisis in the future.
