A researcher whose work was supported by the Federal government, among others, has agreed to retract two of her papers published in 2009 in the pages of Environmental Health Perspectives and the Journal of Biological Chemistry, respectively.

How many of us have had COVID-19 or received vaccinations? The numbers of those inoculated are a bit easier to come by, but to count all those infected we’d have to test everybody. (That hasn’t happened – and won’t be happening.) Knowing the number of asymptomatic transmitters is helpful in both understanding who’s most impacted by COVID-19 and achieving the nirvana of herd immunity. A new study looks at a different population among us: blood donors.

It takes up a third of our life; why do we sleep? Jimming the lock of the lock and key model of biology. How to escape a volcano, like the one on La Palma. The Work Ethic revisited.

The Zika virus is getting a lot of media attention so the Centers for Disease Control has issued an update.

Alarmed by the spread of the supposed “superbugs” — bacteria that resist modern antibiotics — politicians from both parties are considering policies to encourage the pharmaceutical industry to develop new antibiotics. Rep. Phil Gingrey (R-Ga.), a physician, recently introduced the Generating Antibiotic Incentives Now bill, which would extend patent protections for antibiotics for five additional years and speed reviews by the FDA. Rep.

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.

It is an understatement to say that antibiotic resistance is a major problem facing our healthcare system. Every year 2 million Americans are infected with resistant bacteria, and at least 23,000 people die each year from these infections. Each year MRSA kills about as many people as HIV. Compounding this problem is the fact that companies (factory farms?) are actively contributing to this problem (

This is another retrospective observational study, this one from England looking at the transmission of COVID-19 in both its alpha and delta variants to other adults. It helped me refine how I think about vaccines, let me share the findings and my thoughts.

Dr. Fauci, speaking on vaccinations: “Past unsuccessful attempts to elicit solid protection against mucosal respiratory viruses [COVID-19] and to control the deadly outbreaks and pandemics they cause," he said, "have been a scientific and public health failure that must be urgently addressed.” That's a lot to unpack.

As the news cycle brings us more COVID-19 variants and reports of the efficacy of the new vaccines by J&J, Novavax, and AstraZeneca, you have to wonder which vaccine is best and why.

According to an estimate released Monday by the Centers for Disease Control and Prevention, over one million people in America are living with HIV. This towering figure is the highest since the 1980s* and may at first seem like discouraging information. But in fact the CDC report represents both good and bad news about the fight against HIV/AIDS.

A new study suggests that the antiviral Molnupiravir may “paradoxically” be driving COVID-19 mutations, creating variants of concern. What is going on? It is all about molnupiravir’s mode of action and evolution.

The question of the protection afforded by COVID infection vs. the immunity conferred by the mRNA vaccines is still unsettled. A new study may put our concerns to rest. Spoiler alert: each form of immunity has its strengths.

China’s Zero-COVID policy goes against the central idea of the hygiene hypothesis: that to be the fittest to survive you must be exposed to germs. Could China’s current dilemma be sufficient proof of the need for a sweet spot between filth and sterility?

A South Korean company named Seoul Semiconductor claims to have developed an ultraviolet light-emitting diode (UV LED) that can kill 99.9% of SARS-CoV-2 in 30 seconds.

Are viruses alive? Dead? Dead-alive? ACSH's Dr. Josh Bloom posed this question last night on the new ACSH-sponsored Facebook page, Infectious Diseases and Vaccines, with the promise of a Snickers bar for the best answer. He got a ton of responses, including one woman who wrote, They don t contain all of the structures and biosynthetic machinery necessary for reproduction. Their genome is mostly DNA or RNA, but not both like most organisms.

Last week, the FDA and CDC presented their recommendations for the newest round of COVID-19 vaccines. As with everything COVID, there are proponents and detractors, or, putting it another way, both knowledgeable experts and disinformation-spreading attention-seekers. The reality is that a group of experts made a judgment based on actual data.  We discuss the evidence here so you can make your own informed decision.

Being able to treat a bacterial infection with an effective antibiotic is something that we in the developed world have come to take for granted. But the ease with which we're currently able to conquer so many bacterial illnesses may soon come to an end, according to an article in The Lancet Infectious Diseases.

Have you ever forgotten where you put your keys and searched your apartment high and low? Or perhaps, more than once, you forgot the name of someone who had just told you his name. Or maybe you make a shopping list even when your prospective purchases are few.

Our first two vaccines have greater than 90% efficacy; Novavax reports 89.3%, Johnson and Johnson’s reports 66%. Should we care? What do those numbers mean to you and me when we worry about the protection the vaccine affords us?

Hospital employees — including doctors, nurses and others — who wear their scrubs or gowns outside of work may unknowingly pose a public health threat, Dr. Betsy McCaughey told the Pittsburgh Tribune-Review Monday. Founder of the Committee to Reduce Infection Deaths (RID) and Chairperson of ACSH, Dr.

We've just gotten a whole bunch of good news – news we really needed – about finally getting the upper hand against COVID-19. Two vaccines, both more than 90% effective at protecting clinical trial participants against the disease, were announced just seven days apart. These numbers are well beyond expectations, but some critically important questions linger. Here they are. The answers will determine how successful the vaccines will be.

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.

Catchy phrase, but let me ask you this: does it have a different meaning to you when spoken at a Women’s Day rally as opposed to an anti-vaccine mandate confab? It does for me; I wonder why.

The battle of medicine vs. bacteria has been going quite poorly for more than two decades, primarily due to antibiotic resistance. The last thing we need is giving these bugs another edge. But in China, a newly-discovered gene can spread to many types of bacteria, and render useless some antibiotics that are our last line of defense against unresponsive infections.
