The benefits of fluoridated water are well-established but when nature rather than science is in charge it can be harmful. The dose makes the poison and over 200 million people worldwide are estimated to be exposed to high fluoride levels in their drinking water.

A new study finds that long-term consumption of water with fluoride levels far above, 1000 percent more, established drinking water standards may be linked to cognitive impairments in children.

In pursuit of the ambitious goal of reaching net-zero emissions, nations worldwide must expand their use of clean energy sources. In the case of solar energy, this change may already be upon us.

Is it possible for there to be ghosts? – Madelyn, age 11, Fort Lupton, Colorado

---

Certainly, lots of people believe in ghosts – a spirit left behind after someone who was alive has died.

In a 2021 poll of 1,000 American adults, 41% said they believe in ghosts, and 20% said they had personally experienced them. If they’re right, that’s more than 50 million spirit encounters in the U.S. alone.

Harvard University, and its anti-science allies like The Guardian(1) paper in England, are again claiming that meat causes diabetes.

The occasional reader of this blog will excuse me if yet again I do not report here of this or that new result by the LHC collaboration, and instead discuss matters of lesser relevance. But to me, education is important. Even if I am not a University professor, but rather an employee of a research institute (and as such, not obliged to spend some of my time teaching), I do teach courses to university students. I do that because I believe I can give students a positive imprinting on the beauty of physics, on the exciting nature of research in fundamental science, and on how interesting all of that is. 

If you are a parent, or know a parent, you have had someone claim that if their kid eats sugar they get 'hyperactive' - that may happen, but only because a child has been told they get hyperactive and act that way, the same way if you tell a child rum cake has rum they may act drunk.

Biologically, it doesn't work that way. Sugar can certainly help you if you are diabetic(1) and "anti-sugar rhetoric is simply diet-centric disease-mongering engendered by physiologic illiteracy,” according to Edward Archer, PhD.(2)

A new study sought to analyze the chewing nature of four types of gum bases and along the way determine bubbling capacity also. Gums are generally oils, resins, and elastomers generally held in pleasant form by the gum base. 

So gum base is important to manufacturers. Chewing gum is a $25 billion per year business, 1,740,000,000,000 sticks. If humans chew each stick for 10 minutes, that is over 33,000,000 years we spend at it - annually. 

Common sense says that if you have a lot more people walking, often in dark costumes, and just as many people driving, plus more people drinking alcohol than would otherwise occur on a Tuesday, pedestrian fatalities will go up. 

Common sense is right. They will.

Antiviral drugs are generally considered to be a 20th century invention. But recent research has uncovered an unexpected facet to your immune system: It can synthesize its own antiviral molecules in response to viral infections.

My laboratory studies a protein that makes these natural antiviral molecules. Far from a modern human invention, nature evolved cells to make their own “drugs” as the earliest defense against viruses.
