In July, the CDC released a preliminary report showing that opioid‐​related overdose deaths increased 6.2 percent from December 2018 to December 2019. During that same period, deaths due to fentanyl and its analogs increased 15.8 percent. Seemingly in a state of denial, weeks later H.R. 7701 was introduced in Congress, effectively doubling down on clearly failed policies. ACSH advisor Dr. Jeff Singer (pictured) takes a closer look at this issue while examining the wayward thinking permeating the House.

A large study just found that there was little, or no, evidence of cancer linked to the use of hair dye. But one of the most common dyes, para-phenylenediamine, could be reasonably expected by a chemist to be carcinogenic because of the conditions used in the dying process. Even though it's not. Here's why.

Are vaccines going to be adequately tested for safety and efficacy if Phase 3 clinical trials are not completed? Does convalescent plasma work to treat COVID? Is the COVID death toll inflated? We attempt to clarify these controversies.

Here we go: Zombies, in this case, among ants .... What's that listless, unfocused feeling that the time of COVID has created within us? ... Abbott's new 15-minute COVID test explained ... And a book review points out that not telling the public the whole story has historical roots.

Some of you screwballs out there have been complaining that I'm not giving enough chemistry lessons. Be careful what you ask for. Here are a chemistry AND a biochemistry lesson about aspirin and heroin. Don't blame me. Consumer demand rules.

FDA Commissioner Stephen Hahn indicated that his agency would be willing to grant emergency authorization to a coronavirus vaccine, even before it completes Phase 3 clinical trials. This is a reckless gamble and could cause an unmitigated public health disaster.

The COVID crisis, the unrelenting, omnipresent dilemma battering America and altering our daily lives, has commanded our attention like no other health and science issue we've ever seen. But what about other issues, like those involving the effectiveness of ordinary chemicals used around the house ... or highly-dangerous ones that would-be criminals seek to acquire to carry out their premeditated homicides? Yes, our scientific experts are weighing in on those, too, as demonstrated by the varied media coverage ACSH recently received. So from Missouri to Manila, some of the places we appeared in August.

One of the issues in medical data, brought into sharp relief by the pandemic, is what is written on death certificates. For a while, the presumption of a COVID-19 infection without a positive culture was enough to get it listed as a cause of death –- possibly creating a bit of an over-count. But it is not just COVID-19 that is problematic.

Loneliness, if you follow the media, is a problem of old age. It worsens one by one, as you lose your companions. Yet at the same time, it seems to be a problem of adolescence, too, as youngsters tries to find their peeps. So loneliness can affect any age, and a new paper suggests the sources of loneliness change over time.

For everything, there is a time and place. Emergency Use Authorizations by the FDA were necessary for COVID-19's recent past; they are not necessary and will be harmful when applied to a COVID-19 vaccine.

There is no safe way to inject heroin. Narcan (naloxone) may not save your life. Your friends may not be able to, either.

A study early in the COVID-19 pandemic linked air pollution, especially smaller particles, to COVID-19's mortality. As it turns out, and as ACSH scientific advisor Dr. Fred Lipfert points out, the linkage is weak -- at best.

A fact-checking site called PolitiFact weighs in on the validity of the claim that opioid deaths decreased in 2018, thus supposedly marking the first time we are getting control of the "opioid epidemic." Let's fact-check the fact-checkers. Plus, Andrew Kolodny dines on his own words.

A European study found that 44% of "antibiotic-free" animal feed samples tested contained antibiotics.

On tap this time around: Is natural always best, or even better? ... Channeling Rod Serling on digital clutter ... "Slow down, you move too fast" ... How do penguins survive the winter? ... And, can food coloring help against COVID-19?

There are some striking differences between how Europeans and Americans are navigating the pandemic. The latter have a lot to learn from the former.

September marks the 175th anniversary of Scientific American, one of the magazines from a memorable era in journalism that included Life as well as Time – periodicals longer than 20 pages. In honor of SA's anniversary, the editors devoted an article to the words used in articles since the founding of the magazine back in 1845.

As I watch the current debacle of our children preparing to return to school, I more and more feel it is time to take a moment to talk about the errors we have made. My original thoughts turned to responsibility and accountability, words that have occupied my professional life as a surgeon, words molding my thinking just as they molded my character.

If you're someone who believes that the Food and Drug Administration is purely guided by science and that politics has never influenced its decisions, we likely live on different planets. As for some background, here's some recommended reading to go with our overall perspective on this issue.

My PSA was 22 – but my biopsy only showed inflammation. I was needlessly upset, and it seems like I underwent an unnecessary procedure. There has to be a better way!

For every additional microgram per liter of lithium in the water supply, the suicide rate dropped by 0.27 per 100,000 people per year.

Navalny, a Russian anti-corruption activist and well-known critic of President Vladimir Putin, is being treated in Germany for an apparent case of poisoning by an "organophosphorus neurotoxin." But which one: the insecticide or the chemical weapon? Here are some clues.

Another clinical trial of remdesivir – this time with hospitalized patients having moderate COVID-19 – yielded disappointing and strange results. The first randomized trial showed a modest benefit in patients with severe COVID, so theoretically the drug should have worked better in patients who weren't as sick. But, it didn't.

There are any number of papers supporting the idea that higher levels of air pollution are inversely correlated with poorer health outcomes. These studies all suffer from the fellow travelers of air pollution, traffic density, poverty, and lesser education which confound a clear linkage between air pollution and health. A new study offers a possibility.

The most recent workshop of the Beyond Science and Decisions series was conducted at the National Institute for Occupational Safety and Health (NIOSH) in Cincinnati, Ohio, in February of this year.
