The use of deoxyribonucleic acid or DNA to solve crimes is fast becoming a powerful tool due to the incredible accuracy of results when biological evidence is present. In the same manner that it is used to identify the criminal, it can also be used to clear suspects and exonerate persons that have been mistakenly accused or convicted of crimes.

Crimes can be solved with the use of DNA technology in two ways. A sample of the person’s DNA can be compared to evidence from the crime scene in cases where there is an identified suspect. Otherwise, biological evidence from the crime scene can be analyzed and compared to offender profiles in DNA databases. A match helps identify the perpetrator if he/she has already a record on file. A no-match at the very least encourages investigators to pursue other possibilities.

The introduction of the E-plane ended the inability to use an electric motor as the energy source for a manned airplane. The first E-plane was a compact two-seat carbon composite plane powered by Toyota Prius batteries and a 100-hp motor. It had an impractically short range, very much similar to the earliest electric cars. The plane’s range was expected to increase dramatically once it flew on fuel-cell alone.

A fuel-cell airplane is a lot quieter and more efficient wherein the propeller would be the only source of noise. The plane will be able to fly for at least an hour on two pounds of hydrogen. NASA studies suggest that cheaper fuel cells is the most viable alternative to heavy piston engines if the automotive industry would be more open to fuel cell cars.

All the world welcome new inventions for there could never be enough good inventions for mankind who is notorious for causing its own problems. Just how far some “scientists” would go to credit themselves with accomplishments provided by doctored or bogus findings, no one would really know. When scientific findings become inventions themselves, there must be something terribly wrong about the situation.

History would attest to the fact that even if such instances are rare in the science field, they do happen, not exempting even the most popular and renowned scientists. Spurious science reveals itself in many ways. The human brain finds it very difficult to duplicate the elements of randomness of scientific data. Image editing tools can root out signs of image tampering. It could be very hard to imagine what the effects of actual scientific misconduct could do.

What comes next after digital photography? A digital picture frame, of course! Perceived as a natural progression of digital photography, the digital picture frame is the newest way to display your precious digital pictures. It is basically an electronic device which functions like a photo album except much better. It is able to hold thousands of digital photos by simply copying the images onto a small memory card which is inserted into the frame.

Digital photo frames can also display the photos in a TV set and most display the photos to view as a slideshow with adjustable time intervals. Although it typically displays pictures directly from a camera’s memory card, some frames can provide internal memory storage. Others can load pictures over the Internet from RSS feeds.

It has been known for sometime now that criminals leave traces of themselves at crime scenes whether it is in the form of blood, semen, hair or a scrape of skin. A unique genetic fingerprint is left behind that will establish the presence of one person with certainty. Thus is the known side of DNA Testing.

DNA however, has a lesser known aspect to it. DNA traces also leave clues of ancestry and appearance which can eventually be used as a foolproof police sketch. This could be far more helpful to the resolution of the crime than typically unreliable descriptions from eyewitnesses. The science should prove itself reliable especially if there are differences in opinion between the DNA markers.

Standard video conferencing is associated with prohibitive costs. The introduction of web conferencing is an important development in business communication as it has enabled cost to decrease while application increases. More than ever, business can be done in the comfort of people’s homes courtesy of their desktop computer. Web conferencing has allowed users to do many things at a click of a button, doing away with the substantial cost entailed in traveling to do business. It has provided a suitable substitute to face-to-face meetings as users see, hear, text, chat, present and share information.

For all intents and purposes, people can meet through web conferencing whenever and wherever needed as long as the participants have access to an online PC or laptop. High costs associated with bandwidth are no longer a deterrent to communication due to the tremendous savings afforded by web conferencing.
