SUNSCREEN PROVIDE 12 HOURS PROTECTION.

Sunscreens have constantly been scrutinized for further improvement in terms of longevity and composition, on account of it being a high demand product. So this new mixture made out of all natural ingredients with long lasting protection, would be more than welcome.

The ingredients are particular components found in algae and reef fish mucus to concoct a material that blocks both types of UV rays- UV-A (melanoma inducing) and UV-B (causing sunburns).

Current sunscreens have achieved this, but the chemicals used in their making are questionable to our health for long term use, and accidental ingestion.

This discovery of using algae and reef fish mucus is not recent. Scientists have been trying to incorporate a naturally obtained substance, mycosporines, for quite some time in facial sunscreens. But, the mycosporines would just smear and dribble too much to be of any use.

The use of a technique called polymer scaffolding turned out to be the solution. The primary polymer used was chitosan, which is derived from the crustaceans (crabs and shrimps), proved to sustain the film of sunscreen intact for over 12 hours. A wide range of polymers could be used and, this films showed effectiveness both indoors and outdoors of cloths and furniture.

The next step would be to introduce this as a facial brand sunscreen. The FDA would probably readily approve of the products as it uses all natural ingredients.

Check out this latest technology: NASA’s Speedy WiFi Chip- Gimme That!

NASA’s new cool invention of this WiFi chip is going to be in great demand; once it is released in the market. Why? This chip, which can be used in computers, wireless phones, and other electronic devices, consumes 100 times less power than the conventional receivers.

This chip was developed by Adrian Tang, researcher at NASA’s Jet Propulsion Lab in California and, University of California-Los Angeles professor, MC Frank Chang, Extension of battery life in nearly every device that uses WiFi, is guaranteed by using this chip. Amazed? Read on for the mechanism behind this.

The secret behind the chip’s speed is that it doesn’t generate its own signal, but instead, reflects a constant signal sent by a customised router. The data is then imprinted of the signal reflected.

Now, as it imprints the data, and the signal is a reflected one, no power is consumed.

The last problem that now arose, was that of recognizing the correct reflected signal carrying the data.
