As was the case with other "instant therapies" for COVID, convalescent plasma showed no utility whatsoever in a well-designed randomized controlled trial, something that should come as no surprise to anyone who has ever waded in the treacherous waters of drug discovery research. Another one bites the dust.

Environmental Working Group claims that meat "is exacerbating the climate crisis." EWG isn't wrong to point out the environmental impacts of animal agriculture, though the activist group has oversimplified the problem—and its promising solutions.

In a bid to bolster their flagging anti-biotech agenda, several high-profile activist groups have bizarrely joined the chorus of voices suggesting that SARS-CoV-2 escaped from a lab. The science community needs to make clear that wherever the virus came from, its beginnings do not undermine the safety or efficacy of important biotechnology innovations in food and medicine.

The same mRNA technology that gave us effective COVID-19 vaccines could yield a new generation of highly protective seasonal flu shots. When will we see these upgraded influenza vaccines? Perhaps sooner than you think.

Hospital data show that the largest shares of COVID infections and deaths have been to the unvaccinated, about whom we have little personal information. The media has interviewed a few individuals, but large-scale demographic data are needed for a better understanding. A new report from the Centers for Disease Control and Prevention (CDC) may provide some insight.

We're almost two years into the pandemic and there have been more than enough ups and downs to last a lifetime. But now we have a potentially big "up," because the results just came in on Pfizer's COVID drug Paxlovid—and they are nothing short of amazing. Will we finally be free of the terror of this pandemic? Maybe.

What went wrong during the COVID-19 pandemic? A team of public health researchers recently outlined some of the crucial policy mistakes we made and explained how we might avoid them in the future.

The anti-GMO movement is gradually campaigning itself into irrelevance. Unfortunately, this positive trend has been slowed by public universities that pay activists exorbitant speaking fees to promote their questionable ideas. This is but one example of taxpayers subsidizing ideological advocacy with potentially serious consequences.

The Veteran Administration's "Opioid Safety Initiative" – as fine an example of doublespeak as you'll see – succeeded in reducing opioid prescriptions by 64% in less than a decade. That's just fine if you're prepared to accept the accompanying 75% increase in rural veteran suicides. Drs. Jeffrey Singer and Josh Bloom are not. Here's their opinion piece in The Virginian-Pilot.

The process of respiration – converting oxygen to carbon dioxide and energy – is what life is all about. This metabolic process, which humans and animals must do to live, changes the environment when we inhale air and release our breath back into the world. How does COVID-19 fit into this?

Some vaccines are one-and-done, like measles. Others are annual events, like the seasonal flu. There's new data as to where on that spectrum the COVID-19 vaccine lies.

We hope you enjoy this – probably your last – Thanksgiving. Because, as you will see, you'll be scarfing down carcinogens with every bite. Don't believe me? Ask the Environmental Working Group. They'll be only too happy to tell you how these trace chemicals will kill you. For the rest of the ACSH staff, so long. It's been nice knowing all of you.

One recent article in the bioethical literature bemoaned the expense of pursuing this noble career. Worse still, is that no one really knows what qualifies one to practice bioethics. But at $80,000 for advanced certification, it’s still a lot cheaper than a law or medical degree (although perhaps not quite as expensive as a degree in theology – which some claim might be more helpful).

Science journalism is plagued by several critical problems that jeopardize its credibility. If we want the public to be more science-minded, we have to correct these issues sooner rather than later.

Annapurna – goddess of food, Christmas trees, phrases I may or may not miss next year, and do our inner cycles embody our “self?”

A new study suggests that electronic cigarette users may experience strokes a decade earlier than traditional smokers. But the authors have overlooked a more interesting result: smokers who switch to vaping have a lower overall stroke risk.

The CDC recently revised its blood reference value for lead in children. Will this result in better protection for kids from the adverse health effects of lead?

Over the last year, the number of immune individuals necessary to achieve herd immunity has risen from 70% to 90%. Is it even possible to achieve herd immunity? Every other disease has herd immunity; why not COVID-19? And another problem, why is COVID-19 different from its siblings SARS or MERS?

The built environment can heat and cool us, human error, debunking the latke, and who is really anti-nuclear power?

We now have both mRNA (Pfizer, Moderna) and vector (AstraZeneca, J&J) vaccines. As we move to boosters, can we – should we – mix and match? Is choosing one from Column A and one from Column B better, worse, or just the same?

In recent years, the “Death with Dignity” [1] movements have been racking up victories. Thirty years ago, only Switzerland allowed assisted deaths. Today, no less than 12 countries and 10 states plus the District of Columbia sanction (or decriminalize) euthanasia (where the doctor administers a lethal drug) and Medical Assistance In Dying (MAID), when the patient does the deed.

The CDC 2016 Opioid Prescribing Advice, which has caused so much hardship to so many pain patients, has been tossed out and replaced by a revised document. Is it better? Sure looks that way.

An unexpected delay in the FDA's authorization of COVID shots for children under age 5 could amplify parents' existing concerns about vaccinating their kids. Here's what we know about the situation.

The American public has been concerned with radiation safety as far back as the tragic story of the “Radium Girls,” female factory workers who contracted radiation poisoning from painting watch dials with self-luminous paint between 1917 and 1920. While there is substantial data demonstrating powerful carcinogenesis from high-dose radiation, e.g., an atomic bomb explosion, can small doses of radiation cause cancer? Some believe that they can.

All over the U.S. the lines for COVID testing often stretch around the block. You can wait an hour or two just to be tested, before learning that the results are not available when you need them. President Biden is going to send us all two home tests. But what are the science-guided recommendations? The New England Journal of Medicine provides a very reasonable answer, beginning with a simple picture.
