When it rains, when a low-pressure system passes by, and when water soaks the soil, it's not a great day to sample for radon. Those conditions force radon out of pore spaces and into basements.
There have been three major accidents at commercial nuclear reactors – Three Mile Island (1979), Chernobyl (1986), and Fukushima (2011). Let’s take a look at each of these accidents to see what happened.
Shipping regulations passed in December 2020 and poised to take effect in the near future will greatly restrict access to electronic cigarettes. Since the law was enacted, additional research has shown that smokers who switch to vaping have a good shot at giving up cigarettes, and maybe even nicotine, forever. Congress is hindering this important public health victory.
Long before COVID-19, overwhelming infection, sepsis, often bacterial rather than viral, has been a leading cause of death in US hospitals. Sepsis has attracted the concern of Medicare, which requires hospitals to report on their adherence to a bundle of treatment measures. How is that working out?
The recent excellent article by Josh Bloom, “NYC Pol Uses Phony Cancer Scare & ‘Children’ to Ban Glyphosate in Parks,” talks about the scare tactics used by a council member in New York to ban glyphosate (Roundup) from city parks. I’m taking a deeper dive looking at how the WHO’s International Agency for Research on Cancer (IARC) and our EPA determine whether or not glyphosate causes cancer. A flawed process leads to flawed science, which like radioactivity – stays around forever!
Fish + bacteria = 25% mortality. Fish + bacteria + rocks = 5% mortality. What magic lies within the rocks? What can farm-raised fish teach us?
Where does the Earth’s magnetic field come from, why do we think it’s going to reverse itself (and what in the world does that mean, anyway?), and what’s any of that got to do with me or cosmic radiation?
Once we leave the atmosphere and travel beyond the cocoon of Earth’s magnetic field, the radiation environment changes dramatically. With talk increasingly turned towards a return to the Moon and manned trips to Mars, what radiation problems will our astronauts encounter?
The CDC just announced the pause of the Johnson & Johnson vaccine in the U.S. because of six blood clots among seven million people vaccinated. If you're shaking your head trying to figure out why the CDC pulled a life-saving vaccine after a few adverse events so rare -- where you'd have a much greater risk from dying from crossing the street or getting into a car -- you are not alone. Is the U.S. shifting regulatory policy to the Precautionary Principle?
Our country continues to be plagued by maternal deaths, and there are disparities in outcomes when stratified by race or ethnicity. So what’s going on? A new study that looks back over 18 years searches for some answers.
Space is a harsh environment. We’re all familiar with the big risks from television – asteroids, solar flares, lack of air, extreme temperatures, and the occasional testy alien ships. What we don’t think about quite as much is the radiation. With trips to the Moon and Mars, in the planning stages, we are once again about to send people into that harsh universe. In addition to the engineering, logistics, and everything else that goes into such trips, NASA is looking at revising the limits for radiation exposure its astronauts can receive.
Like a number of our friends, my wife and I are switching to a more plant-based diet but still find a steak or fish a good occasional choice. That got us to talking about why some people choose to restrict their diet. In looking for an answer I ran across a plausible explanation, that generalizes to other issues.
