Halloween is just a few days away so prior to worrying about razor blades in candy or kids getting run down in the streets you may want to think about pumpkins.

They are full of toxic chemicals. Even organic pumpkins.

Andy Brunning, of the Compound Interest site, made this graphic for Chemical  &  Engineering News, but they have nothing to do with this article about the dangers of pumpkin chemicals. Theirs is informational, the snark is all mine.

Hurricane Katrina was not dangerous until it hit land in Louisiana. But it intensified and since activists had successfully lobbied the Clinton administration to prevent the Army Corps of Engineers from making repairs, devastation occurred.

Injuries and lives lost may have been reduced if there was a better way to predict when a commonplace tropical depression or tropical storm will intensify. 

A new paper says there’s more than one mechanism that causes rapid intensification. 

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.

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.
