The classic ethical dilemma for autonomous driving is the "trolley problem." It's a binary choice of intentionally killing one person to avoid the deaths of multiple individuals – or yourself – while driving. But should this dramatic “edge case” be the model for autonomous vehicles’ decision-making? A group of researchers argue that more mundane driving scenarios would be better.

In a move that will significantly expand the restrictions on per- and poly-fluoroalkyl substances (PFAS) – more commonly known as the “forever chemicals” – the International Agency for Research on Cancer has reclassified perfluorooctanoic acid (PFOA) as “carcinogenic to humans.” It did so even though no valid studies show it increases the risk of causing cancer in people. How will this reclassification increase pressure in Europe and the U.S. for more action? Here's a look.

The wellness world loves science washing. By using technical-sounding jargon, it’s easy to add a sheen of legitimacy to an otherwise nonsensical product or offering. One of the most recent examples is Functional Blood Chemistry Analysis, or FBCA.

A host of societal problems are associated with social media (SM): Amongst other ills are the dissemination of anti-vax disinformation; being purveyors of anti-Semitic tropes; and fostering narratives resulting in teenage suicide, anxiety, and depression. Until now, host platforms have enjoyed broad protection from legal action –even when dangerous ramifications surface. That may be about to change. 

Winter is here, which means a barrage of pathogens is patiently waiting to make our lives miserable. Influenza, colds, and the "stomach bug" are the top three nasties likely to get you, but can you prevent this by washing your hands or using an alcohol-based disinfectant? Or maybe neither?

In a CBS Eye on the World interview, host John Batchelor and I discussed myriad pressing concerns regarding data security in the healthcare sector.

Was Derek Chauvin's use of force against George Floyd justified? The former police officer's attorney said yes, pointing to a controversial syndrome known as "excited delirium" to explain Floyd's frenzied behavior while in custody. Does this defense withstand scientific scrutiny? Meanwhile, 10,000 steps: it's a magic threshold often used to pinpoint fitness, but there's little evidence behind this popular idea.

The level of respiratory illnesses in the U.S. is high and increasing. We are again experiencing a "tripledemic" of COVID-19, flu, and respiratory syncytial virus (RSV). As the peak incidence of those infections approaches, we should be vigilant and take appropriate precautions.

A recent study from JAMA Internal Medicine documents that in many cases in which a patient has died, the electronic medical record – the baseline truth for Big Healthcare Data – lists them as alive. Does the term "garbage in, garbage out" ring some bells?

In last week’s “Red State/Blue State” square-off between the governors of Florida and California, CA's Gavin Newsom touted his state’s lower per-capita overdose death rate. It might have to do with how the different states compare on harm reduction.

Congestive heart failure refers to the inability of the heart to perform its basic function, which is pumping blood throughout the body. It comes in various forms, causing swelling of the legs and shortness of breath. It is a very debilitating condition that few outside medicine are aware of. A new study offers a unique treatment, but more importantly for our discussion, it sheds light on how “science” advances and looks at an infrequently used term, hormesis.

Anyone who has spent time in a traffic jam waiting to “get somewhere” can easily accept the premise that traffic can raise your blood pressure. If you don’t believe me, spend 30 minutes going 4 miles in Los Angeles or trying to go over the George Washington Bridge in New York at rush hour. A new study suggests that the creeping elevation of your blood pressure is not so much due to your fellow drivers but to pollutants in the air. Obviously, they haven’t driven in Jersey. What could they be thinking?

Sickle Cell Disease is an awful genetic disease that disproportionally affects black people. It's caused by a single-point mutation in DNA, which results in a modified hemoglobin protein, differing by only one amino acid. While this may sound insignificant, it's anything but. Simple organic chemistry explains why this change profoundly affects those unfortunate enough to inherit the disease, which is characterized by abnormal hemoglobin.

Just like a trip to the dentist, it's time for The Dreaded Chemistry Lesson From Hell. This time we'll discuss the element xenon. Also, Dr. Charles "Chuckie D." Dinerstein gets his comeuppance. And a mini-book review. No extra charge!

The need for social distancing and isolation during the pandemic has driven a surge in home-delivered foods and meal kits. Consumers must trust the vendors and shippers to provide logistics, packaging, and shipping policies that ensure safe foods. How well are they doing? 

Social media platforms, fringe websites and activist groups are well-known sources of unscientific nonsense. Less discussed is the fact that ideological activism masquerading as research often finds a home in prestigious academic journals. One journal in particular has a long history of publishing such dubious content—The Lancet.

A recent story from the Associated Press (AP) highlights the many flaws in how we talk about teenage vaping. It's a public health issue that needs to be addressed, but before we can do anything about it, we have to understand the level of risk e-cigarette use actually poses to minors.

The Biden administration announced a "test to treat" plan to provide easy access to Paxlovid – an effective COVID antiviral drug – for anyone who's infected. It's not perfect, but it's sorely needed.

A new study looks at how those, who vape and use hookahs, inhale and exhale. It's an examination of duration, volume, and velocity. In other words, constructing product-specific puff topographies.

Explaining a paradox of science, let nature bury the excess carbon, Power, and letting go – at least of our notes.

Have you ever tasted a medicine pill that’s so bitter that you can barely swallow it? Most adults can handle it. But with kids, bitterness can affect compliance. Here’s some clever chemistry to the rescue.

Virus particles come from people, like you and me, when we are ill, even before we are symptomatic. While the necessity for masks for this pandemic may be ending, barrier face coverings (BFC) may, in the future, reduce exposure to particles of concern - other viruses. Here is the work of my organization.

We're learning more every day about the SARS-CoV-2 virus, but it will likely present surprises. The best strategy is still to prevent new infections.

Canada has approved Medicago's plant-based COVID-19 vaccine. The new shot itself is an impressive development, but the technology it's built on suggests that we may be growing more drugs in greenhouses in the coming years.
