A proposed underwater museum in Alexandria, Egypt, came closer to reality when the UN established a committee to aid the design process with the Egyptian government Shown with a 2008 illustration of the proposed underwater museum, the Bay of Alexandria once contained Cleopatra's island palace and the Pharos of Alexandria lighthouse , one of the seven wonders of the ancient world. Both of them were done in centuries ago by earthquakes.  The proposed museum's underwater facility (at bottom in architect Jacques Rougerie's conception) will be difficult and expensive to build and is the focus of the just launched two-year feasibility study. But planners believe that the benefits of plunging visitors into the historical context of the objects--on the sunken island that once held Cleopatra's palace--will be worth the trouble. The marble head of Roman princess Antonia Minor, mother of Emperor Claudius, rests on sand at the now sunken site of Cleopatra's Alexandria...

Experts have come up with a new security system for Internet using a special laser that may help keep hackers’ prying eyes off for good. Scientists at Tel Aviv University have developed a digital security tool with existing fiber optic and computer technology that transmits binary lock-and-key information in the form of light pulses. The device, invented by Dr. Jacob Scheuer, TAU’s School of Electrical Engineering, allegedly ensures that a shared key code can be unlocked by the sender and receiver, and absolutely nobody else. Dr. Scheuer explained: "Rather than developing the lock or the key, we've developed a system which acts as a type of key bearer.” The researchers continued: "The trick is for those at either end of the fibre optic link to send different laser signals they can distinguish between, but which look identical to an eavesdropper." Dr. Scheuer added: "We've already published the theoretical idea and now have developed a preliminary demonst...

In a new research, scientists have suggested that hot water may sometimes freeze faster than cold because of random impurities in the water. Fast-freezing of hot water is known as the Mpemba effect, after a Tanzanian schoolboy called Erasto Mpemba. Physicists have come up with several possible explanations, including faster evaporation reducing the volume of hot water, a layer of frost insulating the cooler water, and differing concentration of solutes. But the answer has been very hard to pin down because the effect is unreliable - cold water is just as likely to freeze faster. According to a report in New Scientist, James Brownridge, who is radiation safety officer for the State University of New York at Binghamton, believes that this randomness is crucial. Over the past 10 years, he has carried out hundreds of experiments on the Mpemba effect in his spare time, and has evidence that the effect is based on the shifty phenomenon of supercooling. “Water hardly ever freezes at 0 degree...

The structure of the human skin is basically divided into two general layers, the dermis and the epidermis. The latter is divided further into five layers. The layer at the very surface of the skin is called the Stratum corneum, which consists mainly of dead skin cells. The body sheds these dead skin cells on its own accord, however, one needs to take care and sometimes use certain remedies to get rid of this skin. Dead skin cells impact the skin's health. As the dead skin cells build up on the surface of the skin, they can act as a barrier to absorption of nutrients from nourishing creams. Also, they tend to block sweat glands, which can result in whiteheads, blackheads or acne. Here are a few ways one can get rid of dead skin... An exfoliating scrub is the easiest way of getting rid of dead skin cells on your face. Use one with almonds as an ingredient. The essential oil of almonds will help repair your skin. Lather soap on your face, or acne wash if you hav...
