Quick Guide To Instantly Find Out Who Owns a Phone Number

It is very frustrating to receive phone calls from an unknown number with no explanatory voicemail messages to go with them. This could be a single instance, a call at odd hours of the night, or repeated harassing hang-ups. Thanks to advances in phone service and the internet, it is easier than ever to learn how to find out who owns a phone number.

Search Engines
For many numbers, the task of looking up a phone number is as easy as typing it into Google, Bing, MSN, or the search engine of your choice. This tool will access anyplace on the web where the number might show up. Therefore, if the number is listed publicly online, or if there is anyplace on the internet where someone has posted their number, that site will pop up on your search. Sometimes, if it is a telemarketer or a collector, you will find forums where others have listed the number and any information they have found out about it, including who owns the number. If you are unsure how to find out who owns a phone number, this is the ideal place to start.

Reverse Phone Lookup Services
If you are unable to uncover any helpful information using a search engine, you can try to utilize a reverse phone lookup website. The site administrators here understand how to find out who owns a phone number using more sophisticated tools than we have at our disposal online. You will likely learn if it is a land line or a cell phone and where it is based, but if you want to know exactly who owns the number, you may have to pay a fee.

The Phone Service
There are tools available outside the internet as well. If the internet is not turning up any information, you can call your service provider and talk to a representative about the calls. They will possibly know how to find out who owns a phone number; if they are unable to help you, they will be able to make suggestions for blocking the calls or handling them if they are harassing in nature.

Call The Number
There is a chance that if the number is an unlisted cell phone number, you may not be able to uncover the name of the number's owner. If this is the case, learning how to find out who owns a phone number may become something a little more basic. You can call the number. If it is a business, the person answering the phone number may state the name of the company; if it is an individual, you will hopefully get voicemail and the person will state his or her name.

If you choose to use this route, be sure to call from a public phone or block your own call on caller id. If you are calling from a land line, you can dial *67 before calling. If you are calling from a cell phone, your service provider can tell you the procedure for blocking your number.

'Watermark Ink' chip can instantly identify liquids

If you want to know exactly what a substance is, your best bet is to use something like a gas chromatographer. The problem is, such machines tend to be large, lab-based and expensive - not the greatest for use in the field, or by people who aren't connected with a research institute. Researchers from Harvard University's School of Engineering and Applied Sciences, however, have created inexpensive, portable 3D-nanostructured chips, that can instantly identify any liquid via its surface tension.

The chips utilize something known as the "Watermark Ink" or "W-Ink" concept. W-Ink is based around a fabricated material called inverse opal, which has a layered glass structure with an internal network of ordered, interconnected air pores. By selectively treating certain parts of the inverse opal with vaporized chemicals and oxygen plasma, the Harvard researchers have been able to alter the properties of those pores and the channels between them. Depending on how those pores are altered, they will only allow liquid with a specific surface tension to flow into them. If that liquid is able to enter the pores, it alters the opal's optical properties, causing it to change color.

Single chips can be "tuned" to test for multiple liquids, producing a different type of color change in the presence of each one. They require no power source, and can be reused many times.

Old school spies could even find them useful, as they can be treated to reveal written messages when subjected to the right liquids - they can even contain several messages, each one becoming visible using a different solution.

The Harvard team are hoping to commercialize the W-Ink technology, and are currently working on calibrating the chips for use in quality assurance and contaminant identification. Their research was recently published in the Journal of the American Chemical Society.

The video below shows how the chips can react in different ways, to different liquids.
