Translates mechanism and epidemiology without dumbing them down, and reaches for the historical parallel. Seven years covering biotech and public health.

Autoimmune & Inflammation

Histamine Was Always the Wrong Target for the Eczema Itch

Eczema itch runs on cytokines, not mainly histamine, which is why the pills in the allergy aisle keep failing the trials, and a network meta-analysis just said so one more time.

Nutrition & Food

The FDA Revoked Two Petroleum Dyes That Industry Abandoned Before Most Americans Were Born

Orange B was last certified in 1978. Citrus Red No. 2 has painted Florida oranges since 1959. The six petroleum dyes actually in the food supply remain on a voluntary timeline no manufacturer has publicly signed.

Infectious Disease

Five Years After COVID, Japan Is Still Dying at Pandemic Rates, and Confirmed COVID Explains Only a Tenth

Japan's excess deaths peaked at 7.55 percent in 2022 and still ran at 5.76 percent through 2023, after Tokyo downgraded COVID to a routine infectious disease, in one of the most heavily mRNA-dosed countries on earth.

Infectious Disease

Against Omicron, a Second COVID Dose Added Almost Nothing for Kids Who Were Already Infected

In Austria's own registry, one dose protected previously infected people slightly better than two; in children against the omicron they actually faced, the second dose's benefit could not be told apart from zero. The guidance never moved.

Drugs & FDA

The Last Time Washington Went After Hospital Drug Markups, the Supreme Court Blocked It. This Time CMS Brought Receipts.

In 2018 the Supreme Court blocked CMS from cutting the markup 340B hospitals charge Medicare for discounted drugs, because the agency skipped a required survey. CMS ran the survey this time, and found seniors paying co-pays bigger than what the hospital paid for the drug.

Two Journals That Buried the Lab-Leak Question Now Warn of a 'Gilded Age' in American Science

The Lancet and Science marked America's 250th by casting the administration's research cuts as vandalism. Both journals spent the public trust they now invoke, and the editorials never mention how.

Cancer

One Protein Keeps Your T Cells in the Fight. The Same Protein Feeds Autoimmune Disease.

In mice, deleting the LEF1 gene collapsed the reserve T cells that sustain the fight against chronic infection and cancer. The same deletion protected against autoimmune diabetes.

Europe Called Medical AI 'High Risk' and Still Gave Patients No Right to Refuse It

An algorithm once cut the extra care flagged for Black patients by more than half, and ran for years before anyone noticed. A commentary in the Journal of the Royal Society of Medicine says the rules now governing medical AI would not have caught it.

Drugs & FDA

The FDA's Fix for a $10 Billion Flood of Chinese Vapes Is a Form the Smugglers Will Ignore

Foreign manufacturers ship most of America's vapes and falsify the customs forms to do it. Washington's answer is to ask them to register with the agency they already evade.

Infectious Disease

The Same System Now Racing to Test a Bundibugyo Ebola Vaccine Had Nineteen Years to Build One

Bundibugyo Ebola was identified in 2007. By the time this year's outbreak passed 1,200 cases there was still no licensed vaccine and none in clinical development. Now roughly $75 million is moving to test three experimental shots on the people dying from it.

Infectious Disease

The Gut Lining Starves Salmonella of Iron, a Trick We Thought Only Immune Cells Knew

Salmonella sickens more than a million Americans a year. University of Vermont researchers found the cells it invades fight back by withholding the iron and manganese the bacteria need, a defense the textbooks credited mainly to immune cells.

Infectious Disease

Most of These Ebola Patients Aren't Bleeding. That's Why It's Spreading.

A Bundibugyo virus outbreak in DRC and Uganda has topped 1,100 confirmed cases, yet roughly nine in ten patients show no bleeding, the symptom everyone is trained to look for.

Infectious Disease

A Blocked Vaccine Study, and the Statistical Method Its Own Lead Author Warned About

A CDC vaccine-effectiveness study pulled from the agency's own journal landed in JAMA, and the press called it censorship. The method it used has a documented blind spot its own lead author once published on.

Cancer

A Cancer Algorithm Found Answers in 71 Children. The 'Quantum' Label Is the Least Interesting Thing About It.

A University of Utah team used the linear algebra of quantum mechanics to pull two survival predictors from just 71 neuroblastoma patients. The science is real. The word doing the marketing is not.

Infectious Disease

The Ebola Vaccine We Celebrated Doesn't Touch the Strain Now Burning Through Congo

Congo's Ebola outbreak has passed 1,000 cases and is rising faster than any before it, but it is caused by Bundibugyo virus, against which the licensed Ebola vaccine and antibody drugs were never designed to work.

Investigations

A Top Cancer Scientist, a Deleted Study, and the Question Washington Won't Fund

A June 2026 Senate subcommittee hearing centered on a Brown University cancer researcher's review of 333 post-vaccination cancer case reports, and on the retractions, censorship, and cyberattack that met it.

Investigations

Retracted by Its Title: A Vaccine-SIDS Paper and a Standard That Isn't Science

A vaccine-safety paper sat in a peer-reviewed journal for five years, then was pulled in 2026 with a critic saying its title alone disqualified it. The science against the paper is strong; the retraction that followed wasn't science.

Brain & Aging

A 14-Patient Hand-Exoskeleton Study Lands in Science Advances, With a Headline That Outruns the Data

A Vienna-led team published a 14-patient feasibility study of a wearable hand exoskeleton with closed-loop electrical stimulation. The mechanism is genuinely novel; the headline is doing work the data cannot.

Drugs & FDA

Moderna's mRNA flu shot got a 9-0 vote. The comparator question that killed its first filing did not go away.

An FDA panel voted 9-0 to back Moderna's first mRNA flu vaccine. Four months earlier, the same agency refused to even read the file over the comparator the trial used. The comparator did not change.

Drugs & FDA

A $200 Flu Pill Just Got a Cheaper Twin. The 10 Percent Resistance Problem Came With It.

The FDA cleared the first generic of baloxavir, the one-pill flu drug, in time for the 2026–2027 season. Cheaper is real. The mutation that turns the drug into a sugar pill is real too.

Infectious Disease

Decades of Failed Diarrhea Vaccines Kept Hitting the Wrong Coat. A WashU Team Just Found the Scissors Underneath.

A WashU-led team identified a structurally conserved patch on three mucus-cleaving enzymes that ETEC, Shigella, and other gut pathogens all use to breach the intestinal barrier, offering a single antibody target the field has chased for decades.

Infectious Disease

American Infant Mortality Just Hit a Record Low. The International Comparison Is Half an Accounting Trick. The Mississippi Gap Is Not.

Preliminary CDC data put the 2025 U.S. infant mortality rate at 5.4 per 1,000 live births, a record low. The international comparison the headlines lean on is partly an artifact of how countries count. The domestic gap is not.

Brain & Aging

The Shingles Vaccine Keeps Cutting Dementia Risk. The Reason May Not Be the Shingles.

Four big studies now tie the shingles vaccine to lower dementia risk. The most useful finding is that the same effect shows up with an RSV vaccine that shares its adjuvant.

Drugs & FDA

Astellas Brings Real-World Numbers for Its Menopause Drug to ENDO 2026. The Black Box Warning Stayed Home.

Astellas presented its first real-world numbers for Veozah at ENDO 2026, framed as a win. The 656-woman observational study had no placebo arm and the company's release did not mention the FDA black-box warning for liver injury.

Drugs & FDA

Testosterone Prescriptions Quadrupled. The Workups Didn't.

A Michigan Medicine chart review presented at ENDO 2026 found that only 12 percent of men prescribed testosterone got the guideline-required workup, even as the U.S. wrote 11 million testosterone prescriptions in 2024.

Drugs & FDA

A DoD-Funded Fentanyl Vaccine Is Headed to Phase 1. Antibodies Don't Stop a Supply Chain.

A Pentagon-funded fentanyl vaccine licensed to startup ARMR Sciences will begin Phase 1 in the Netherlands in early 2026. Three decades of failed addiction vaccines, and a supply chain that runs through Chinese precursor labs, are the context the press release leaves out.

Infectious Disease

The Battlefield Medicine Revolution Was Built on Fake Wounds

A British prosthetics graduate is heading to NHS ambulance crews and the British military to build realistic trauma wounds, the artisan end of the twenty-year battlefield-medicine revolution that turned hemorrhage into a survivable injury.

Nutrition & Food

The thin trial behind England's next supermarket-layout mandate

A non-randomized trial of 36 English discount stores produced a moment-of-implementation bump in produce sales that lost statistical significance by three months, and a household-purchasing signal that never landed. The authors' immediate call for a national layout mandate is the louder finding.

Infectious Disease

A 16-month-old died at an Arkansas splash pad. Its chlorinator had been broken for a month.

A new global synthesis on free-living amoebae explains why a single bad month at a public splash pad is enough to kill a child, and why the CDC's existing protocol would have caught it.

Investigations

A Senate Subcommittee Just Put the COVID Shot Cancer Question on the Record

A Senate Homeland Security subcommittee took testimony on whether mRNA COVID shots can plausibly cause cancer, and on the parallel campaign to keep that question out of the journals. Dr. John Campbell walked his audience through it.

Nutrition & Food

The supplement aisle has spent twenty years getting older Americans wrong

A May 2026 review by two geriatric researchers, syndicated this week by ScienceDaily, restates what twenty years of trial data have already shown: the supplement aisle is built around vague promises older Americans do not need, while protein, the gap that actually moves aging outcomes, sits in the m

Alnylam Bet $2 Billion on AI-Designed RNAi. The Check It Actually Wrote Was $30 Million.

Alnylam paid Inceptive Nucleics $30 million up front, with up to $2 billion in milestones tied to outcomes the rest of AI drug discovery has spent a decade failing to deliver.

A Senior NIAID Scientist Got Caught Smuggling 113 Vials Through Detroit. He Says He Does It All the Time.

Two NIAID scientists are charged with bringing 113 undeclared vials into Detroit during an active Congo mpox outbreak. One allegedly told a federal officer he does it all the time.

Infectious Disease

Xocova clears the FDA. What it actually prevents is the smaller story.

The FDA approved Shionogi's ensitrelvir for post-exposure COVID prevention, citing a 67% relative risk reduction. Look at what the trial actually measured and a different story comes into focus.

Drugs & FDA

Hepatitis Delta Has Waited Forty-Nine Years for a Drug. The FDA Made American Patients Wait Three Extra.

The FDA cleared bulevirtide for chronic hepatitis delta this week, six years after Europe started using it and three years after a U.S. application was turned down on manufacturing grounds. The wait is its own story.

Infectious Disease

America's Ebola Fortress: History Has Tested This Strategy, and It Failed

Washington has built a wall around the Ebola outbreak in Central Africa. The last time America tried this, the evidence says the wall leaked, and so did the response.
