Self Healing Electronics

This in an article from Huffington Post, a famous website which contains all kinds of articles. The article does not display a specific author, which because the article is originally from EarthTechling. The original article was written by Angeli Duffin who is doing product design and development with Fair Trade artisans around the world, she then moved on to the editorial side, writing for eBay’s Green Team blog and working as a marketing consultant for social and environmentally minded companies. Huffington Post is very famous and well-known, and the author has a lot of experience in the environmental theme. Therefore, this article is valid because the author has lots of experience in the field and Huffington Post is very famous.

The article talks about the possibility of self-healing electronics rising from the amounts of e-waste being produced. It says that the devices (in order to reach our demands) use integrated chips which increase the likelihood of a circuit break that could shut down the whole system as the device heats up or becomes fatigued. These devices are easy to replace, which ends up generating e-waste. The article describes that to solve this, the Illinois team devised a system to place tiny microcapsules on top of a gold line functioning as a circuit. When a crack occurs, the microcapsules break open, releasing liquid metal that fills the crack in the circuit, repairing the electrical flow. This would be the self-healing device.


Satellite Imagery in China

The article is from a website called SpaceNews which offers a distinct online information portal, delivering accurate, timely news and in-depth analysis, in addition to a variety of custom publishing options. The article was published by Peter B. de Selding who earned a B.A in political science at Washington College and a Master’s Degree in Journalism from Missouri-Columbia. Therefore, we can observe that the site is popular in the space field, showing that it has been very popular for the last two decades. Also the author is very well educated, and is properly trained to write an article, specially in the political front, which is an aspect, aside from space, that this article takes on. Also, this author wrote various other articles on the webpage, therefore he has experience writing in SpaceNews. Ergo, this article is valid because of its popularity and experienced author.

The article explains the launch of the DF-2 satellite in China, which is capable of producing images with a ground sampling distance of 80 centimeters in black and white, and 3.2 meters in color. Its images have a width of 48 kilometers, and the satellite is capable of swiveling on its axis 35 degrees to either side. It also explains that China  has been one of the world’s biggest markets for commercial Earth observation satellite imagery and how its increasing self-sufficiency has  cost several satellite image providers like RapidEye of Germany.

Weather Forecast Technology

This article was posted in the site Scientific American which is a magazine published in 1845 and is the oldest continuously published magazine in the U.S. In this magazine, lots of nobel prize scientists have contributed articles. The article is written by Jane Lubchenco and Jack Hayes. As observed, the magazine is very well-known and prestigious, therefore the content in is valid.

The article starts off with an example of the Hurricane Joplin that hit the USA in 2011, it ended with 550 casualties. This hurricane was warned 20 minutes before it hit the USA. Now, tools for forecasting extreme weather have improved, and now extreme weather can be warned of an hour before it actually occurs, which gives the family enough time to prepare and take shelter. Radars are used to predict these extreme weathers and although the Doppler Radar does have flaws, it can distinguish a rainstorm from a dust storm. Forsyth, a meteorologist, has since focused on upgrading radars. One critical upgrade is called dual polarization. This technology allows forecasters to differentiate more confidently between types of precipitation and amount. The understanding of particle size helps to produce more accurate forecasts, so residents know they should prepare for hail and not rain, for example. This article is relevant to the topic we are studying because it shows how weather forecasting technology and its improvement can be the difference between life and death, as it gives people enough time to prepare for extreme weather.

Electronic Prescribing

This review is posted on The National Center for Biotechnology Information which advances science and health by providing access to biomedical and genomic information. It contains medical information, therefore it can be assumed that the contents of this review can be trusted as the site focuses on medicine.

The review show how Electronic Prescribing affected the field of medicine. Before its introduction medication errors, which were the mayor type of medical errors, where something that factored in the quality of patient care and as it states,  nearly 100,000 individuals per year in the US died of preventable medical errors of with 7000 were medication errors. The introduction of Electronic Prescribing, which is Computerized Physician Order Entry systems, lowered this number down and also improve the quality of patient care. However, it shows some negative effects, including the facilitation of medication error risks or an increase in mortality. This is relevant to what we are studying because it shows that the implementation of technology in the field of medicine saves lives and it drastically improves patient care quality, making it easier to access information needed.

Technological Surgery

This article is from Imperial  BRC which is a National Institute for Health Research, therefore can be trusted in the field of medicine. The Imperial BRC develops technology for medicine as well as conducting research.

The article explains the use of surgical technology in health care. It says that the Imperial BRC constructed a Surgical Robot called i-snake “to facilitate large area in vivo tissue imaging and characterisation through the integration of miniaturised reflected white light and fluorescence intensity imaging for MIS.” It shows various examples of the implementation of technology in medicine, such as Robotic Assisted Technology, using robotic assisted MIS, which allows procedures to take place that would otherwise be prohibited by the operating environment. It is relevant to the topic we are studying because it depicts the use and aid of technology in medicine, which in some cases helps to give a more precise outcome, and in other cases its implementation actually allows the procedure to occur. It also provides a safer work space, and also a safer procedure as it is more precise than the human hand and it therefore avoids risks that could mean life or death.

Wearables and Trackables – Their Impact

This in an article from Huffington Post, a famous website which contains all kinds of articles. The author of this article is Ali Cherry who is a Student and Teacher of healthy habits and is also the founder of Snack Packers. This shows that she is really immersed in the topic of health and therefore we can trust that this article is valid.

This article talks about how people are getting into the habit of collecting their personal health numbers of steps, blood pressure and much more. Wearable devices like Fitbit and MyFitnessPal are the ones responsible for this collection of data. It is relevant to what we are studying because it shows the impact that technology has on, not only big industries as we know, but also on a human being’s personal life. A person can now keep track of their fitness and are therefore able to take better care of theirselves on a daily basis, ergo avoiding medical problems. However, it also arguments that these wearables may, in the long run, outsource the monitoring of our bodies and making ourselves dependent on technology to take care of ourselves. These trackers help us know what is good and bad in our body when we take a jog or a walk, as it registers many data of our body that is useful and can tell us if we need to improve on something.
