The hottest Regulatory reform Substack posts right now

Better AI-designed molecules won't automatically make clinical trials faster, because timelines are set by human biology, patient recruitment, logistics, and regulatory processes that take real calendar time.
Clinical trials do two jobs—validation and learning—and AI needs rich human trial data to improve; many important outcomes, especially for chronic diseases and aging, take years to observe so trials remain slow even with better drugs.
Real acceleration requires institutional and regulatory reforms—like validated surrogate endpoints, streamlined review pathways, and better data sharing—because AI alone can only improve trials at the margins until those systems change.

A federal judge halted the CDC's January 2026 immunization memo and froze recent ACIP appointments and prior ACIP votes, which in practice blocks the administration's vaccine schedule reforms across the country.
The court relied on FACA and arbitrary-and-capricious reasoning to question the new ACIP's balance and member qualifications. Its treatment of a long-time vaccine researcher as lacking relevant expertise looks like judicial substitution for executive judgment.
The administration has strong grounds to appeal, arguing the stay functions like a nationwide injunction under APA §705 and raising core separation-of-powers questions about who gets to set public health policy. Higher courts may need to decide whether lower courts can use APA stays to produce nationwide effects despite limits on universal injunctions.

Radiation harm depends on how fast damage happens relative to the body's repair systems, so the full dose‑rate profile matters more than total dose or a simple average rate.
Nuclear fission is extremely energy‑dense and can provide very cheap, low‑carbon power, but fear‑driven regulation based on the linear no‑threshold idea has inflated costs and blocked that potential.
Proposed reforms are concrete: adopt a dose‑rate‑aware Sigmoid No Threshold model and restructure regulation and liability to balance benefits and risks, and manage spent fuel with short pool storage, dry casks, reprocessing for breeder material, and vitrification of leftovers instead of deep geologic disposal.

The president, who doesn’t drink or smoke, signed an executive order to reschedule marijuana and speed up federal review.
Rescheduling could loosen regulations, reduce tax burdens for cannabis companies, and open the door to federal recognition of medical marijuana.
The move breaks with traditional Republican drug-policy stances and has unsettled some conservative allies, even as the cannabis industry has long leaned toward Democrats and progressives.

Lawmakers are moving to close loopholes for special government employees and curb potential self-dealing.
The proposed bill would bar many SGEs and their companies from getting more than $1 million a year from the federal agencies where they work.
It would also create a searchable database to track SGEs because there’s currently no centralized disclosure system.

Bipartisan environmental reform is hard to achieve because Republicans and Democrats have different ideas on what needs changing. One side wants to make building easier, while the other focuses on renewable energy.
Many lawsuits against projects can cause delays and make them financially unfeasible. Even if most of these lawsuits fail, they still create uncertainty that can halt progress.
Current environmental policies and lawsuits can block innovation instead of helping the environment. A reset might be needed to improve infrastructure and address climate change effectively.

Arizona needs to simplify its housing permitting processes to build more homes faster. Doing this would help meet the growing demand for housing and keep prices more affordable.
Many local governments in Arizona hinder the construction of new homes, especially multi-family units. This has contributed to rising home prices over the past decade.
The challenges Arizona faces with housing development are similar to those in other areas. The solutions proposed for Arizona could be helpful for improving housing issues in many other places as well.

Robert F. Kennedy Jr. moved from environmental law into a prominent role challenging pharmaceutical and public health institutions and now serves as HHS Secretary pushing anti‑corruption reforms.
His policy agenda focuses on three pillars — transparency, detoxification, and decentralization — including public access to raw trial and CDC data, phasing out suspected toxic chemicals, and breaking up concentrated federal health authority.
A major CDC audit under his leadership reportedly uncovered data suppression, conflicts of interest, and questionable handling of autism data, leading to legal referrals, grant freezes, and plans to release terabytes of raw epidemiological data for independent review.

Understanding the FDA's approval process for drugs includes stages like drug discovery, preclinical studies, clinical trials, and regulatory approval.
The FDA's accelerated approval program, initiated in the 1990s due to HIV/AIDS, aims to speed up bringing life-saving drugs to market for urgent conditions, but follow-up studies are crucial.
FDA approval decisions hinge on expert clinical judgment, balancing benefits and risks for patient safety and efficacy, a process that involves multiple stakeholders and extensive data evaluation.

Cities can improve public transport by building small tunnels to connect existing train lines, making systems more efficient without huge costs.
New Zealand's unique approach to controlling inflation changed how many countries handle their economies, showing that bold ideas can lead to widespread change.
Lead poisoning is a big global issue that can be mostly solved with actions that have worked in wealthier countries, like testing and regulating sources of lead.
