Pop Quiz: You open the refrigerator and pull out a tasty treat. It’s May 6 and the label says: “Use By” May 4. Do you eat or toss? And what if it said: “Best if Used By”? Although you think you know the correct answer, most of us don’t.

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.

The anti-biotech movement continues to warn that consuming GE crops makes people sick. A recent email blast from The Institute for Responsible Technology typifies the latest arguments coming from activist groups. How well do these stand up to the facts?

In a pandemic, will physicians, who determine that the potential benefit of Ivermectin outweighs its well-documented risks for their patients, finally once again be given free rein to practice medicine?

Last week, the American Council on Science and Health posted an article entitled, “Ivermectin Gets A Randomized Clinical Trial. The Results Are Not Promising.” The article focused on a JAMA paper, “Effect of Ivermectin on Time to Resolution of Symptoms Among Adults With Mild COVID-19A Randomized Clinical Trial.” The article noted the findings, made observations about other completed trials and the problems with them. 

Despite evidence that all the approved COVID-19 shots drastically cut the risk of transmission, the CDC insists that vaccinated individuals still have to mask up and keep their distance. This policy may do more harm than good as we try to further boost vaccine uptake.

What d’ya say – want to design a nuclear reactor? And why not? It’s a slow day, and what else are we going to do?

Energy fuels our growth and maintenance. How exactly that changes, and the relative contributions of exercise and metabolism over time, is difficult to ascertain. A new study provides some answers. It is both dynamic and, as is often the case, nuanced.

The creative class, the elites and the bobos, deep concentrated work, death and evolution, shopping, and of course, COVID-19

After a short gestation period, COVID-19 vaccines arrived throughout the nation and became part of the daily scene. Questions about which vaccine to get have diminished replaced with concerns about who is getting shots and who is not. Here is what the latest statistics tell us.

The pandemic chaos continues...

Always eager to win friends and influence people, The Conversation recently published an article claiming that people who refuse to get COVID shots are selfish and un-American. This is not how you convert vaccine skeptics.

Dr. Jeff Singer of the Cato Institute, and also a member of the ACSH Board of Scientific Advisors was invited to participate in a panel discussion on ending the opioid crisis. Here is a description of the event and a link to a YouTube video of the discussion.

On February 9, 2001, the Ehime Maru, a Japanese trawler off Diamond Head in Hawaii, was rammed and subsequently sank by the USS Greeneville with the loss of nine lives. The Naval Court of Inquiry found the captain responsible. What does any of this have to do with COVID-19, let alone swiss cheese? Let’s start with the findings of the naval inquiry that will get us to the cheese.

According to a recently released study by the Environmental Working Group (EWG): “Wireless radiation exposure for children should be hundreds of times lower than current federal limits.” It recommends stricter, lower exposure limits for all radio frequency sources, especially for children. Is there a reason for concern?

Stuart Little aside, laboratory animals aren’t people. And – yes – I know that this is pretty obvious to most of us, but it needs to be said. This is one limitation in studying the effects of…well…anything on rats and mice and applying the results to humans.

To a physicist, every moment of every day is filled with radiation.

Last week with little fanfare, the Environmental Working Group released its latest “report” on the putative harmful effects of cellphone radiation. Right from the start, it features two eye-catching words, "radiation" and "children."

Roughly 70% of Americans have gotten or plan to get vaccinated – a percentage that has not changed since June. The public remains divided between those that fear the virus and its consequences and those who fear the vaccination.

June and July saw substantial changes in the progression of the COVID-19 pandemic, essentially reflecting the competition between relief from vaccination and the spread of the more contagious delta variant of the virus. These changes varied by time and place; here we seek perspective by examining temporal trends in six regions of the US [1]

Is there *nothing* so offensive and juvenile that it's off-limits, even to me? Maybe not.

Masks offer some protection against COVID-19 infection, but not nearly as much as the authorized vaccines. By telling the public they have to continue masking after immunization, we all but guarantee skeptics will forgo both shots and masks.

I've been following (and writing about) Antibe Therapeutics' otenaproxesul, an atypical NSAID without the GI toxicity of Aleve or Advil, since early 2020. It's been nothing but good news. Until now. Otenaproxesul caused a substantial jump in liver enzymes in some clinical trial participants. Can the company overcome this? Wall Street sure doesn't think so.

Studies investigating serious side effects associated with the COVID-19 vaccines are beginning to give us a better sense of how safe the shots are. Despite what you may see on Twitter, the evidence continues to show that vaccination poses minimal risk to the vast majority of people.
