Dangerous Gases Beware! MIT Creates a Travel Sized Toxin Detector

In 2014, roughly 6.7 out of every 1,000 people were harmed by some sort of dangerous chemical in the United States alone. While this may not appear to be an opposing sum, a little math inevitably reveals that this resulted in 2.2 million exposures to poisonous gas. While a superfluous amount of these deaths claimed children as their victims, other age groups, such as teenagers and young adults were the second most susceptible to toxic gas attacks.

In order to find a solution to this toxic issue, scientists at MIT have created a sensor highly sensitive to dangerous amounts of toxic gasses, as well as being able to communicate with you through wireless smart devices.

Originally intended for soldiers since their standard equipment often lacks toxin detectors, the sensor is fitted with carbon nanotubes that act as a form of insulation. The molecular structure of these tubes break down when in contact with toxic gasses, such as carbon monoxide. Upon breaking apart, the nanotubes are able to physically come in contact with one another, creating conduction, which then allows a signal to be sent to your smart device.

For added insurance, the signal requires no internet connection, insuring the user safety wherever he or she may go. Although the product hasn’t passed the final stages yet, the company C2Sense is preparing it for commercial use, with the expected release date looming around an unspecified date sometime next year.

When Life Gives You Heart Problems

…Make lemonade. At least, that’s the motto of nine-year-old New Mexico resident Addison Witulski.

Upon finding out that her grandparents were concerned with getting her younger brother Kaden to Houston, Texas for a heart surgery, Witulski decided to take matters into her own hands. She rounded up her friends Emily and Erica Borden and set to work selling cups of ice cold lemonade and one of a kind drawings crafted by Witulski herself.

Though her drinks and works of art only sold for around twenty-five cents each, the determined group of girls made over $500 to donate to the younger Witulski sibling’s journey to Houston.

Kim Allred, grandmother and caregiver of Addison and her little brother, was floored by the the depth of human kindness expressed by such a young soul. Allred says of her granddaughter: “She helps me more than I help her sometimes.” She also describes the sense of amazement she felt upon realizing that the nine-year-old could have just as easily spent her hard earned cash on new toys or clothes, but instead stuck to her goal of helping her brother get his heart surgery.

To help their efforts, a few of the local police officers also paid a visit and purchased a cup of their own, bumping up the girls’ grand total to $568.10.

Aside from his sister’s successful lemonade business, Kaden’s family has also set up a GoFundMe account in the hopes of garnering more support for the young boy’s surgery. Check it out here: https://www.gofundme.com/263zwec

A Low Salt Diet Could Cause Cardiovascular Disease

People suffering from high blood pressure are recommended to consume low sodium meals. In fact, most people are supposed to take a maximum of 2.3 grams of sodium a day, the amount present in a teaspoon of salt in a day.

New York Times however has recently reported that it is actually a low-sodium diet that would increase the chance of cardiovascular risk, referring to a review of studies conducted this year. The research was an observational review comprising 113,118 people who were investigated for a period of 4 years. Scientists recorded their blood pressure readings and approximated their level of sodium consumption by urinalysis.

Among 65,559 individuals who never contracted hypertension and consumed more than 7 grams of sodium every day, none of them increase their chances of contracting any cardiovascular disease. However, for those who consumed less than 3 grams of sodium every day, 26% of them increased their risk of death from cardiovascular events like for instance heart attack and stroke. This is in comparison to their counter parts who utilized more than 5 grams of sodium in a day.

Among those with blood pressure, those who consumed more than 7 grams every day increased the risk by 23% while those who consumed less than 3 gram increased their risk of cardiovascular death by 34%.

This prompted Dr. Andrew Mente, an epidemiologist at the University of McMaster, to saying that eating less salt does actually lower blood pressure. Moreover, it is not wise to consider blood pressure alone, but rather the actual clinical event. This is because less salt will expose you to critical cardiovascular diseases including stroke, heart attack and mortality in both the long run and the short run.
