Reports of junk DNA’s ‘demise’ were based on junky logic and dubious definitions
Science is an oddly successful enterprise. On the whole, it provides an impressive guide to reality. From antibiotics and atomic bombs to laser beams and X-rays, science enables humans to forge powerful tools from nature’s secrets. Yet many aspects of science are deeply flawed, from the politicization of research funding to widespread misuse of math […]

Humankind’s destructive streak may be older than the species itself
Some scientists have proposed designating a new geological epoch, the Anthropocene, that would cover the period since humans became the predominant environmental force on the planet. But when would you have it begin? Some geologists argue that the Anthropocene began with the Industrial Revolution, when fossil fuel consumption started influencing climate. Others point back several […]

A theorem in limbo shows that QED is not the last word in a mathematical proof
When a top-tier mathematician announced in August that he had proved one of the greatest problems in mathematics, the claim was trumpeted in the New York Times, Nature, Science and the Boston Globe. But that didn’t make the abc conjecture proven. People often think of mathematics as a solitary pursuit, with a written proof as […]

Real-life Maxwell’s demon adds fuel to debate about status of the second law
Fight Club had its First Rule (don’t talk about Fight Club). The Transporter enforces Rule Number 1 (never change the deal). And NCIS Special Agent Leroy Jethro Gibbs observes Rule 1 (never mix the suspects together in the same room). Physics has the second law of thermodynamics. It’s weird when you think about it. Movies […]

A mathematician puts Fermat’s Last Theorem on an axiomatic diet
Fermat’s Last Theorem is so simple to state, but so hard to prove. Though the 350-year-old claim is a straightforward one about integers, the proof that University of Oxford mathematician Andrew Wiles finally created for it nearly two decades ago required almost unimaginably complex theoretical machinery. The proof was a dazzling demonstration of that machinery’s […]
