Kids Who 'Skype A Scientist' Learn Science In A Whole New Way

July 24, 2017 - 2:30pm

Although most people have been in a classroom, hospital, courtroom, etc., almost no one has been in a laboratory. So, how is anyone supposed to understand how science is done or who is doing it? A new program run by a graduate student called "skype a scientist" is looking to change that.

Can You Hear Me Now? A Tale of Hearing Impairment and Alzheimer's

July 24, 2017 - 1:00pm

I am of an age when my ability to not “hear” my wife is becoming less a spontaneous reaction and more a physiologic one. I just don’t hear as well as I did ten or fifteen years ago and I have been known to spend more than a few moments looking for my cell phone. So I was particularly entranced by a headline that said that hearing loss, among other “modifiable factors,” might be involved in the development of dementia.

The Chicken May NOT Cross The Road! We Will Need New Jokes

July 24, 2017 - 11:16am

When it comes to survival, birds are not birdbrains. 

A recent Australian study in the journal Frontiers in Ecology and Evolution found that birds can adapt to urban environments better than we thought. But before we get to that, I do have a bit of a problem with one sentence in the introduction:

LNT at Cato, We Take Down Junk Science in USA Today, and More Outreach

July 24, 2017 - 10:23am

1. Dr. Julianna LeMieux and I were at the Cato Institute for the Dr. Ed Calabrese talk on the linear no-threshold model (LNT) used to set regulatory limits.

Members of our Board of Scientific Advisors, like Dr. Jerry Cutler and others, have long-considered LNT to be the Patient Zero of junk science used to create regulations. It basically says that particle 1 is as harmful as particle 1,000,000. Also mixed in the discussion is hormesis, a u-shaped curve in dose-response, which can also be controversial when misused by activists.

Some Diagnoses Are Just Junk Medicine

July 21, 2017 - 3:55pm

Some medical diagnoses are like fad diets — everyone you know has chronic Lyme disease or gluten intolerance, if not out and out celiac disease (whether a medical test confirms it or not). But many are just junk medicine, just as many fad diets are junk nutrition.

July 21, 2017 - 12:51am

New research suggests that saffron -- a spice used in some Asian, Indian, and Mediterranean dishes -- may have an intrinsic ability to fight cancer. But don't get too excited. Research on antioxidants suggests the same thing, but they fail in clinical trials.

Vitamin D Doesn't Help Kids Avoid Colds

July 20, 2017 - 5:37pm

Although some observational studies have suggested that vitamin D can help prevent upper respiratory ailments in adults, no such data substantiates that claim for children. And a new study that compared low and high dose vitamin D with respect to such problems in kids found no effect at either level. Sorry, parents!

The Alzheimers Association’s International Conference is underway in London which might explain an uptick in reports on Alzheimer's in the popular media.

Chipotle or Shark Attack? You're Safer with Sharks

July 20, 2017 - 12:15am

In 2015, you were roughly 16 times more likely to get food poisoning from Chipotle than you were to be attacked by a shark. We can't remove all the sharks from the ocean, but we can remove pathogens from our food. Chipotle should have focused on that, instead of GMOs.

Is Chipotle Really A Bioweapons Research Lab?

July 19, 2017 - 11:44pm

What's happened to Chipotle during the past two years is too bad to be true. The food chain has given a whole bunch of people food poisoning, especially from norovirus. But the virus rarely strikes in the summer, so how did it end up hitting the same chain again? Could this be a conspiracy? Is Chipotle actually making the virus? Put on your tin foil hats and read this.

If you believe the hype that the Organic Consumers Association puts out, you believe that organic foods are better for you than the conventionally raised variety. And you likely also believe that animals raised in line with organic principles are also treated more humanely. Oops!

July 19, 2017 - 12:59pm

Heavy metals get a bad rap. For the most part, it is deserved because they are usually toxic. Except when they aren't. You have probably consumed a whole lot of at least one or two of them and are just fine. Here's why.
