Most of us think of sound as something we can hear: music, speech, barking dogs, thunder, or the roar of traffic. But an enormous acoustic world exists beneath the threshold of human hearing. Known as "infrasound," these ultra-low-frequency vibrations — generally below 20 hertz — travel invisibly through the atmosphere, oceans, and even the ground. Although largely imperceptible to us, they carry extraordinary information about the natural world and human activity. And, in turn, they can affect how we feel and act.

Scientists are increasingly using infrasound to monitor volcanoes, detect meteors, track storms and nuclear explosions, and possibly improve warning systems for dangerous weather events.

Those who pay attention to our environmental issues and are old enough will probably remember the Love Canal disaster of the 1970s: A Niagara Falls, New York, neighborhood had been built on top of 21,000 tons of toxic industrial waste, and leaking chemicals caused high rates of cancer, miscarriages, and birth defects. It led to forced federal evacuations and prompted the creation of EPA's Superfund program to remediate toxic wastes.

Sadly, the online environment populated by today's youth, sometimes as young as grade schoolers, has grown as polluted – by intellectual, not chemical, waste. By allowing this to occur, we are betraying entire generations, failing our duty of care.

Florida's citrus industry is fighting for its life. After two decades of devastation from bacteria-caused citrus greening disease — known scientifically as huanglongbing, or HLB — production has collapsed from more than 250 million boxes in the early 2000s to a tiny fraction of that today. Growers have endured hurricanes, shrinking acreage and the slow death of millions of trees. Now, the state is planting more than 300,000 citrus trees developed using CRISPR gene-editing technology, hoping to restore an industry that once defined Florida agriculture.

This is a story of scientific ingenuity and economic urgency. But it is also a story of regulatory inconsistency that risks slowing the very innovations Florida desperately needs.

There is a particular kind of government betrayal that arrives not with a bang, but with an obscure bureaucratic memo. No dramatic announcement, no press conference, no honest accounting to the public.

Just a directive, handed down through internal channels, instructing scientists to withdraw publication of their work — work they spent years producing; that taxpayers spent millions funding; that concluded, simply and clearly, that FDA-approved vaccines are safe.

That is what has been happening at the FDA. And it should disgust and anger every American who has ever trusted a public health institution.
