America’s top health official is advocating for a nationwide ban on lab-grown meat, arguing that it is a risky corporate experiment that should not become part of the country’s food supply.
Robert F. Kennedy Jr., serving as Secretary of Health and Human Services, has expressed strong opposition to cultivated meat. He has directed the FDA to strengthen oversight of these products and has voiced support for state-level bans, arguing that cell-cultured meat is an unproven, ultra-processed food whose long-term health effects remain uncertain.
Supporters of Kennedy’s position say a cautious approach is warranted. They argue that the lab-grown meat industry could concentrate control of the food supply in the hands of a small number of large corporations and investors. Under Kennedy’s leadership, HHS and the USDA have also shifted federal dietary guidelines to place greater emphasis on traditional livestock products and full-fat dairy as part of a conventional diet.
Critics, however, argue that cultivated meat has the potential to reduce factory farming, lower greenhouse gas emissions, and help meet the food demands of a growing global population more efficiently than traditional meat production. They contend that the central question is whether Kennedy’s actions are intended to protect public health or to preserve the existing food system from emerging competition.

For two centuries, the laws of thermodynamics have governed our world. They run your car engine. They keep your kitchen fridge cold. We built the modern industrial age on them. There was just one problem. The math was mostly an educated guess.

Thermodynamics has always relied on engineering intuition rather than precise fundamental proofs. It worked, so we used it. But now, physicists are going back to the foundations. Led by Bryan Roberts at the London School of Economics, they are rebuilding the math from scratch.

They are using ‘gauge theory’—a complex geometric framework usually reserved for quantum physics. They are finally establishing a mathematically bulletproof bridge between classical heat and work, and the subatomic world. It takes thermodynamics from a practical rule of thumb to a rigorously grounded science.

For 17 years, “courage can be contagious” was the phrase Captain Chesley Sullenberger used to describe that freezing January day in 2009, when he landed a crippled airliner on the Hudson River and walked away with all 155 people on board.

Yesterday, at 75, he revealed a new chapter.

Sully has early-stage Alzheimer’s.

He says the changes started small — a name that doesn’t come as easily, a story he’s already told once before.

His doctor at UCSF told him this disease spares no one, young or old, and touches millions of families quietly, often in silence.

But silence isn’t Sully’s way.

He decided to speak up, hoping other families facing the same diagnosis won’t feel so alone in it.

His wife Lorrie says he’s still the same steady man the world watched on TV that day in the Hudson.

And Sully says the same courage that got everyone off that plane safely is the courage he’s leaning on now.

In September, he’ll be inducted into the National Aviation Hall of Fame — proof that Alzheimer’s can affect his memory, but it can’t touch his legacy.

If courage really is contagious, Captain Sully is spreading it one more time.

What do you want to say to him?
