Has Apple Reinvented The Touchscreen?

Thursday, January 8th, 2009

All the top stars on the block seem to be heading with single-minded determination towards the same goal. Blackberry, Sony Ericsson, Nokia, and Google is not to be left behind too. It is extremely impressive to watch the unfolding of the “touchscreen” era.

This was exclusively the domain of the enterprise phone segment just a little while earlier. But things have changed so fast that there perhaps may not be a cell phone manufacturer that does not wish to proudly lay claim to this distinction.

We will have to give credit to the keypad. Even with the possibility and threat of being ousted looming large, it still manages to hold its head high, with the hope that the competition does not invade its territory. As of now there are more phones that come with only a keypad when compared to touchscreen phones. In fact many of the touchscreen phones also have a keypad. (more…)

Engineering Artificial Life!

“Somewhere something incredible is waiting to be known.” ~ Dr. Carl Sagan ~

Man built many things with the help of science, but there has always been something that has been out of reach for man – creation of life. This has always been the domain of the “creator of the universe” and man could not transcend this.

Latest reports reveal that this is about to change and scientists have come closer to being able to put life into non-living things – once a humanly unthinkable task.

Scientists have taken several steps towards realizing one of the most magical moments for mankind. This crucial step involves the creation of a synthetic chromosome from scratch that will help create artificial life forms. This incredible human intellect accomplished the feat of making DNA fragments using lab chemicals and then assembling them in a cell. This genome contains all that an organism needs to live and reproduce. The organism in the study is called Mycoplasma genitalium, which is the tiniest bacteria ever found, and consists of 582,970 fundamental building blocks of DNA, making it longer than any previous genetic material ever created through chemicals. Not only that, unlike viruses made by humans, synthetic bacterium had the capacity to make copies of itself through cell division.

Initially, scientists started with building long strands of DNA. Each one was a quarter copy of the whole M genitalium genome. These strands were inserted into yeast cells, which stitched the strands together and made clones of the whole genome. Then this synthetic chromosome was inserted into a cell, in order for it to reproduce and create a new life form. (more…)
