One Breath Closer…

According to the World Health Organization (WHO), the leading cause of death worldwide is cancer. More specifically, lung cancer is the most common type of cancer in the world. This terrible disease does not discriminate when it comes to victims. It afflicts both genders, and people of all ages and ethnicities. Luckily, scientists have been working on a new detection device for lung cancer that holds promising benefits for patients. We are literally one breath closer to early detection and treatment of this terrible disease.

The article, Ground-Breaking Lung Cancer Breath Test in Clinical Trial, published on February 14, 2015 states that a breath test shows hopeful advancements in detecting lung cancer. Scientists at the University of Leicester have begun the clinical trials of the Lung Cancer Indicator Detection (LuCID) project. LuCID is a device that detects Volatile Organic Compounds (VOC) at low concentrations in a patient’s breath. The evaluation of VOC’s in a patient’s breath can serve as a biomarker to detect lung cancer.

Dr Siddiqui, the lead researcher in this study, states that lung cancer has one of the lowest survival rates of all cancers. More importantly, he emphasizes the importance of early detection to improve a patient’s prognosis. Basically, the earlier the cancer is discovered, the greater the chance of survival for the patient. For this reason, the LuCID device may just be the missing key to early detection. The device is also cheaper, more efficient, and less invasive compared to other detection methods. For example, performing a CT scan exposes the patient to harmful radiation that could result in further health complications. Another downside to invasive techniques is that they are not suitable for everyone, especially children and pregnant women. Overall, the breath test is a safer alternative to more conventional lung cancer detection methods.

Though the LuCID project is still in clinical trials, it is showing promising results in early detection for lung cancer. Catching lung cancer at an early stage can give patients a much better chance at fighting this disease. Furthermore, this new procedure may potentially lead to more safer and non-invasive detection methods for other diseases as well.

Understanding Hacking in the News

Video: “Hack reveals scandalous Sony secrets” uploaded by CNN

I’m sure you’ve heard about the most recent Sony hack and the following controversy regarding the movie “The Interview” that depicts a plot to assassinate the leader of North Korea. Sony isn’t the only company to get hacked, and they certainly won’t be the last, but the following information should help you understand the jargon you might hear in the news when the next attack happens.

Let’s start with phishing. This is the type of hacking that you will likely hear about most because it happens all of the time. It is usually done by sending out mass emails in the guise of a legitimate financial or institutional service asking to confirm payment or Social Insurance Numbers. This technique is used to steal a person’s money or identity. When you hear about these attacks in the news, or even from an institution, you generally hear something like “There have been recent reports of fraudulent emails sent to you from us. Please do not respond or open them.” Even UBC staff and students have been affected.

The next form of hacking used to be the go-to for TV shows and movies from the mid 2000s when someone hacked into another’s computer. That’s right, the Trojan virus. Again, the Trojan virus usually targets individual people; however, it is often used to get past the gates of a company’s system. In this case, an email will be sent to a large list of individuals with a file attachment (usually a photograph or document) that disguises the malicious program built into the file. Once you open the file the harmful program will start running. A program like this can do all sorts of awful things from completely wiping your computer of all of its data, recording every key stroke, or collecting all of your data. It is believed that the most recent Sony Pictures Entertainment hack–the one that fueled harsh words and actions between the US and North Korea­–began with a Trojan virus.

Finally, the other most common attack you will hear about is denial of service. Now, denial of service itself is not a form of hacking, but a result of certain attack strategies. The goal with this type of attack is to suspend or interrupt a service so that the company providing the service loses money or users. The strategy to cause this interruption almost always includes overloading the system by causing too much traffic on, or to a website. A good example of this was was when PlayStation‘s network was so overloaded by millions of fake users that it had to be shutdown.

By now, you are probably thinking that the Internet is a very dangerous place, which it is. The first step in protecting yourself is with strong passwords. The CBC reported ways to make your passwords stronger, with it, SplashData’s list of the most used passwords in 2014 (please don’t use “123456” like many other people did). Additionally, the Government of Canada has provided a wealth of information on how to protect yourself from cyber criminals.

Living LARGE

What do you think of when you hear the phrase “living large”? Well, most of us will think of an individual who is living life to the extreme, maybe spending a ridiculous amount of money or living a very extravagant lifestyle. However, for far too many parents and children in North America, “living large” has a very serious and negative connotation. I am referring to the epidemic of obesity in children in North America. Fortunately, a new study has shown that a program that aims to reduce childhood obesity is working well in the U.S.

The study, “Changes in Body Mass Index Associated With Head Start Participation” focuses on a program funded by the U.S. government for low income households. The Head Start program focuses on health, nutrition, exercise, and early education for the young children. Basically, the program promotes healthy living and provides a well-structured plan to achieve it. The program includes health and nutritional services, such as meal plans, activity outlines, and family counselling.  The study looked at two groups of children, one with a healthy BMI and another who were overweight or obese. The researchers monitored the children’s BMI throughout two academic years. The study led by Dr. Lemung found that children who were obese  and overweight who participated in the program had a significantly healthier BMI by kindergarten than those who were in a primary health care system.

Furthermore, a recent CBS news article published in January 2015 focused on the obesity epidemic amongst children in the United States. The article states that about a quarter of the children from ages two to five are either obese or overweight. Moreover, it states that as children enter adulthood, obesity seems to follow. Unsurprisingly, this trend is noted to lead to future health risks for the children. The health risks include a higher chance of developing diabetes, heart disease, lung disease, and much more.

Unsurprisingly, young children living large with no plans to improve their health can threaten their future wellbeing. We need to ensure younger generations are able to thrive in the future and not be held back by complications of obesity. Fortunately, programs such as Head Start have shown to prevent and treat obesity at a very young age. In conclusion, more programs and preventative measures for obesity should be implemented around the world. In turn, these type of initiatives will provide a great way to ensure children get a “head start” in living healthy and not LARGE.
