Science Snippet: ATP ’s Amazing Power

Just as electricity powers almost every modern gadget, the tiny molecule adenosine triphosphate (ATP) is the major source of energy for organisms’ biochemical reactions. ATP stores energy in the chemical bonds that hold its three phosphate groups together—the triphosphate part of its name. In the human body, ATP powers processes such as cell signaling, muscle contraction, nerve firing, and DNA and RNA synthesis. Because our cells are constantly using and producing ATP, each of us t...

What Are K2 and Spice Anyway?
Chances are, you’ve probably heard about the new trend in synthetic cannabis products either from your local news media or from your ongoing EMS education. Over the past few years, these products have been increasing in prevalence around the US and in Europe. But what are these products anyway? Are they cannabis or not? Are they legal to posses? Are the effects similar to traditional marijuana?
Here’s a quick rundown of what EMS folks should know about this new and growing trend in street pharmacology.
Synthetic cannabis products have a variety of street names including Spice, K2, Herbal Incense, Potpourri, Barel...

Rapid Diagnosis: Pinpoint Pupils
Abnormally constricted or “pinpoint” pupils are a great finding for our rapid diagnosis series. There are many things that can cause the pupil to abnormally dilate. Very few things will make the pupil abnormally constrict. Constricted pupils are a doorway to a very short list of ailments and with a bit of background you should be able to hang your hat on one fairly quick.
How So We Assess For “Pinpoint” Pupils?
Recall that the pupil should be mid-range and reactive under normal lighting conditions. When subjected to bright light, the pupil will constricted to reduce the volume of light entering the iris. In d...

Submersion Vibes and Intentions
In my previous post, I invited people to enroll in the new Submersion course deep dive on Subjective Reality, which is the perspective that you could be living in a simulation or dream world of some kind. So far 211 people have signed up, which is awesome! I expect that many more will join by the deadline on Thursday, November 3rd.
In this post I’ll share more about the intentions and vibes that I imagine for this 60-day group experience.
Instead of using only words, I’m going to communicate this in a very visual way – with lots of imagery that I created with the help of machine intelligence, Pixelmator...

Quiz: Antibiotic Resistance and Researchers Studying It
Antibiotics are a class of drugs that treat bacterial infections. They may seem common now, but they were discovered less than a century ago. In 1928, Alexander Fleming, a scientist studying bacteria, found that mold from his bread kept bacteria from growing. He determined that “mold juice” was able to kill different types of harmful bacteria, and he and his assistants worked to figure out what natural product in the mold was actually causing the killing. It turned out to be penicillin!
Thanks to Fleming’s discovery, doctors have been successfully treating bacterial infections with penicillin and other newer anti...

Wearable EEG Patch Measures Brain Activity
Researchers at Osaka University in Japan engineered a wearable electroencephalography (EEG) device that can measure brain activity, potentially letting clinicians monitor conditions such as depression or dementia. At present, assessing brain activity requires a trip to a facility with bulky and expensive equipment, making long-term monitoring difficult. This latest technology aims to allow for at-home measurements of brain activity.
The device consists of a near-transparent patch that is flexible and stretchy. The adhesive patch can be worn on the forehead and provides brain activity readings that are comparable in acc...

Rheumatic heart disease – Cardiology Basics
Rheumatic heart disease – Cardiology Basics
Rheumatic heart disease is a group diseases which occur secondary to heart valve damage from rheumatic fever. Rheumatic fever is a disease in which antibodies produced by the body against streptococci cross react with different tissues in the body, especially the heart.
Group A beta hemolytic streptococci causing sore throat are involved in the pathogenesis of rheumatic fever. Most of the long term damage following rheumatic fever is caused by damage to heart valves . Initial manifestation of rheumatic fever is with polyarthritis, usually of the large joints.
But it does no...

In Other Words: The Measure of a Mole
When we encounter the word mole, some of us might think of a small, fuzzy animal that burrows in gardens, or perhaps the common, pigmented marks on our skin. But in chemistry, the mole is a key unit of measurement; its name is derived from the word molecule. Similar to how “dozen” is another way of saying 12, “mole” is another way of saying 602,214,076,000,000,000,000,000 (that’s about 602 billion trillion), specifically for elementary entities such as molecules and atoms. Scientists sometimes abbreviate this number as 6.02 x 1023, which is why Mole Day is celebrated from 6:02 a.m. to 6:02 p.m. on October 23 each...

National Chemistry Week: Recent Interviews With NIGMS-Funded Chemists
Credit: ACS Website.
It’s almost National Chemistry Week (NCW)! Each year, the American Chemical Society (ACS) unites scientists, undergraduate students, high school chemistry clubs, and other groups through this community-based program to reach the public—especially elementary and middle school students—with positive chemistry messages.
Local groups plan and coordinate NCW events, so while they vary across the country, they often present chemistry education through hands-on science activities to local schools, museums, scouting groups, or Saturday Science events. Lily Raines, Ph.D., manager at the ACS Office of ...

A Small Lifespan Study of Combined Interventions
My attention was drawn recently to a small mouse life span study run by one of the groups that has been in the longevity community for a while now. It is interesting for testing combinations of interventions that have in the past been demonstrated to modestly slow aging in mice (such as rapamycin), or modestly improve aspects of cell function in old tissues (such as nicotinamide mononucleotide). Combinatorial studies are rare in academia and industry, for reasons that have a lot to do with (a) the perverse incentives produced by the existence of intellectual property, in that the rights to use specific interventions can be...
