While wireless devices have allowed us to use more compact and portable devices it has also increased exposure to hackers. In an article that I recently read in science I found out that wireless pacemakers have been made. It is controversial as some people believe that it will make people with wireless pacemakers more susceptible to hackers. This is because if someone were able to hack into a wireless pacemaker device that regulates a person’s heart beat they could then potentially have the power to stop the person’s heart from beating.
However I do not think this is a major concern as I beleive most people do not have the ability to hack into a wireless pacemaker. It would only become a problem if the person with the pacemaker has a position of higher notice as it would make them vulnerable to hackers. Still I think the regular person would not need to worry about someone hacking into their wireless pacemaker.

What a pacemaker does is it manages how the heartbeats, it is used by people with irregular heart beats. People with irregular heartbeats require a pacemaker to send electrical impulses in order to correct their irregular heartbeat. This is important as people with a slow heartbeat could die in their sleep if their heart begins to beat even slower during sleep.

Still a wireless pacemaker is be beneficial compared to the previous available technology. As previous pacemakers required a chest incision in order to be placed inside the heart, but wireless pacemakers do not require an incision. Instead a catheter (a thin tube) is used to place the smaller pacemaker in its correct position in the heart. Another benefit is that it requires fewer follow up placement surgeries as previous pacemakers had lead wires which would sometimes dislocate from its position and require more surgery.
Overall the wireless pacemaker has made it easier for doctors to place inside patients’ hearts and has removed the need for incision surgery. Most importantly it has become the smallest pacemaker available for patients with irregular heartbeats.

Today in grocery stores you will be able to find a mix of fresh fruit and frozen fruit. At first I believed that fresh fruits must be the healthier and more nutritious option between the two. However after researching I found out that frozen fruits holds qualities that allow it to be just as nutritious as fresh fruit.
Below is a youtube video by Dole frozen that describes how frozen fruit is made.
Frozen fruit and fresh fruit share a similar growing process as they both grow on land the part where the process starts to differentiate is when the fruit is picked for processing. Fresh fruit is picked before it has even ripened so that its deterioration during processing and shipping is limited. On the other hand frozen fruit is picked once it has fully ripened, this is allowed as the process of freezing the fruit acts as a preservative that limits the amount of deterioration that occurs. Freezing fruits dramatically slows down deterioration rates, as a result nutrients such as vitamins and antioxidant levels stay relatively similar to the time when it was frozen. This is good as fruit begins to lose its nutrients right after it has been picked thus it is beneficial to eat a fruit right after it has been picked. As most of us do not have access to fruit that has just been picked we have to go for the next option, which may be frozen fruit.
Still fresh fruit has its benefits in particular frozen fruits often contain higher sugar levels. This is because fruit companies may choose to add sugars to enhance the taste of frozen fruit. By doing so these fruit companies increase the sugar content people intake when they are eating fruits. While adding sugar to frozen fruits may cause some people to enjoy eating fruits more it comes at the cost of increasing the amount of sugar intake per fruit which ultimately increases the amount of calories being eaten.
However there has been a steady increase in popularity for frozen fruit this may be attributed to its ease in preparation compared to fresh fruit. Unlike fresh fruit that has to be washed and sliced frozen fruit comes ready to serve and use. For those of us that want to spend less amount of time preparing meals frozen fruit is the more convenient option.

Regardless I think that both fresh fruit and frozen fruit has its benefits and downfalls but the most important idea to keep in mind is to be actively trying to incorporate fruits into diets.

Recently I read an article published in the journal Nature that talked about the possibility of making transparent devices. This was intriguing as transparent phones only existed in the movies but now it may be possible to see them being sold in stores in the coming years. The article says that it would be relatively easy to make most parts of a regular phone translucent. The hard part would be making a translucent battery and SIM card. Specifically making a translucent battery would be the hardest part. Luckily a researcher at Stanford figured out a way to make lithium ion batteries appear translucent. To do this the researcher suggested decreasing the size of the battery so that it is invisible to the naked eye. While the battery would still be opaque it would be so small that people would not be able to detect it.
At the time the article was published in 2013 rumors had been circulating that certain companies were planning to release a translucent phone within the next year. However three years later translucent phones have not yet made it into the consumer market. This was surprising to me, as there seemed to be consumer interest in purchasing redesigned translucent phones. This led me to research further to find out if the reason behind this was a problem with the feasibility of making a transparent phone. For those who are interested there is an exiting app that allows your phone to appear translucent by using the camera on the phone.

After researching I found out that the problem was with the transparent screen. In particular having two transparent screens would make it hard to see images, as there would be no background to light up the image. Although by simply adding more light power to the screen would increase the visibility of images it would in return use up too much of the batteries power. This would result in a short battery life that would be out competed by batteries of regular phones. As a result we are still waiting for a breakthrough to occur in the making of transparent devices.
below is a YouTube video that summarizes some events that have occurred with the making of the translucent phone
