Recent advances in Laser Scalpel technology have made it possible to target individual cells without harming any surrounding tissue. Before this advancement laser scalpels could only be so precise because the heat coming from the laser would actually damage surrounding tissue. This increased precision is made possible by the use of extremely fast light pulses that don't take enough time to hurt the surrounding area. The latest development is not so much the technology itself but the work of rocket scientist Adela Ben-Yakar who was able to shrink the technology to make it possible to work inside humans for surgery. This new technology will undoubtedly help in recovery periods after surgery considering there will be less damage.

The search continues, scientist are still looking for new and inexpensive ways to deliver insulin into the blood stream is one important avenue for tackling the diabetes epidemic that is sweeping our nation and the world. The preferred option for many patients would be an insulin pill taken orally. But studies have long shown that insulin is easily broken down by the digestive system and that any surviving hormone is not easily absorbed into the bloodstream from the gut. An insulin inhaler made it as far as the US market in 2006, but was withdrawn a year later because it wasn't cost effective. rodents got their new treatment in liquid form, "but chewing gum would be a better delivery method in humans" said "the team" Chewing would ensure a plentiful supply of saliva, providing the protein needed for the insulin to make its way into the bloodstream.therefore this is something that i wold invest in as new and upcoming thing
Radio frequency identification ("RFID") is a technology that uses radio waves to identify things. An RFID system includes three elements a tag, a reader, and a database. An RFID tag comprises a chip that contains a unique number that identifies an object.
The simplest RFID tags are "passive" and they do not carry their own power supply to enable data transmission. Passive tags receive their power from the electromagnetic waves. Other tags like "active" do contain some form of power supply allowing the broadcast of information to the reader. Active tags are often able to transmit over a much longer range than passive tags like about 100 feet or more.
RFID technology can be mainly used for keep track of objects, keep track of people, to provide services, or as an internal component of a product or device.
RFID technology could be used in wal-mart as clipped tags instead of bar codes, it can be used in hospitals for the newborn babies, it can be used in an ambulance to locate the a patient, it can be used to find a criminal, and much more. But RFID can be dangerous in privacy concerns. RFID can be found in a person's credit cards, clothing, EZ-pass, and it can also can be found in a humans body. This RFID is able to find your location, personally identifiable information, and most of all, it can track you. So now you have be careful and make sure that RFID is not attached to you.
