This Live Science article covers a set of beautiful equations, nominated by scientists, that describe the nature of the world. It’s worth reading for a glimpse into the beauty of mathematics and its power to illuminate the fundamental laws that govern the universe.
Students at Carnegie Mellon University (CMU) have created a wrist oximeter that monitors blood oxygen levels and can warn the wearer and others of an impending opioid overdose. Opioids such as heroin depress the central nervous system, including respiration, and an overdose kills by suppressing respiration to the point that a person’s heart and brain dies from insufficient oxygen. The CMU wrist oximeter continuously monitors oxygen levels and when low blood oxygen is detected, it will warn the wearer and can also send a text message to an emergency contact.
The Harm Reduction Coalition has a set of web pages explaining the principles behind an overdose and how the drug Naloxone (Narcan®) works to quickly reverse the effects of an opioid overdose and prevent death by restoring the central nervous system to normal operation and thereby restoring normal respiration.
For those interested in a more in depth exploration of the effect of heroin on mammals (rats are used in this experiment), I found the study Intravenous Heroin Induces Rapid Brain Hypoxia and Hyperglycemia that Precede Brain Metabolic Response helpful.
It’s worth noting that Naloxone is relatively easy to administer (with training available) and can be purchased without a prescription. This Time article has details on the legality and availability of Naloxone. If you’re around someone who uses opioids, having Naloxone available could save their life.
This 18 minute video provides a very good explanation of video displays and human vision.
This PDF/guide is worth reviewing if you want to understand enough about optical networking to plan/design networks.
I was surprised to learn that wasps also pollinate. I thought they were just hateful murderbugs. I like bees because they’re prolific pollinators and (in my experience) not as prone to stinging us.
It’s worth reading this short piece to learn how important wasps are to the environment and how poorly they’ve been treated relative to bees by the scientific community.
This Nib comic does an excellent job of explaining the origin and history of hysteria. Everyone should learn this history because hysteria is an accessible and profound example of the harm patriarchy does to all of society: men, women, and children.
NASA has a cool site where you can see in real time what NASA’s Deep Space Network is up to, what spacecraft it’s communicating with and where they are.
This is an excellent comic on the current crisis of reproducibility in science, outlining the nature of the problem, aggravating factors, and what scientists are doing to address it.
Reproducibility is a foundational idea in modern science and should be a required component of secondary education.
