The mystery of vaping deaths widens. What is going on? Let's ask Steve. We go back a long way, so when a tricky chemistry problem comes up we like to fire off an email, to pick his warped brain. Often he is right on the mark.

Yes, 65. Here are the articles we have published on the opioid crisis written by ACSH's Dr. Josh Bloom. Grouped and categorized, we're also providing his research to date as a reference guide for media.

Two recent observational studies found that remission from Type 2 diabetes is as easy -- or hard -- as losing a significant amount of weight.

When it comes to energy and climate policy, there's little rationality to be found. Those who believe that climate change is an existential threat often reject nuclear power in favor of wind and solar, despite those options being insufficient to power the planet. That said, to embrace nuclear energy, we also must have a realistic solution to the problem of waste.

The anti-nuclear crowd uses an assortment of scare tactics to turn public opinion against the use of nuclear power. One of them is highlighting the risk of a serious accident, that might occur when spent nuclear fuel is transported to a disposal site. Is there any validity to this? A visit to the National Museum of Nuclear Science & History in Albuquerque, NM tells us there is not. (It's actually very safe.)

In the conversation about Medicare for All, do you really know what Medicare provides? It may be surprising what a bargain it is, especially compared to private insurance.

The denial of prescription analgesic medication to chronic pain patients has caused unnecessary suffering. But it has also driven up the suicide rate, trapping those who cannot bear to live without the drugs that have kept them functioning for years. ACSH advisor Red Lawhern, Ph.D., discusses the tragedy of intolerable pain.

In the insane universe of dietary fads and fears, at any given time there's always a food that is "super" and another that is a "killer." With rare exceptions, both descriptions are wrong. One of the perennial "bad guys" is high fructose corn syrup. Nutritionist Angela Dowden explains why the reputation of HFCS is not deserved.

Scientists have discovered molecules that inhibit tumor growth by starving cancer cells of their favorite foods: the sugar glucose and the amino acid, glutamine.

Parents and children reading together - the idea may conjure up images of a child safely snuggled in bed sharing a quiet moment with Mom or Dad. But when the book is an e-reader, a new study suggests the scene is more reminiscent of two kids fighting over who gets the remote control.
