Un hombre exhala durante el uso de un cigarrillo electrónico en Portland, Maine.

El presidente estadounidense Donald Trump anunció que buscará prohibir la mayoría de los cigarros electrónicos saborizados. Este anuncio tiene una buena intención —lo cual es raro en su administración— pero eso no hace que la idea sea menos estúpida.

Es razonable preocuparse por el aumento masivo en los últimos años de adolescentes que utilizan estos cigarros electrónicos o vaporizadores. El gobierno estadounidense, bajo la guía de Scott Gottlieb, el excomisionado de la Administración de Medicamentos y Alimentos (FDA por sus siglas en inglés), decidió correctamente al tomar medidas enérgicas contra las compañías de cigarros electrónicos que vendían productos ricos en nicotina a los adolescentes.…  Seguir leyendo »

President Trump’s announcement Wednesday that he will seek to ban most flavored e-cigarettes comes from a good place — a rarity in this administration. But that doesn’t make a ban any less stupid.

It’s reasonable to be concerned about the massive surge in teen vapers over the past few years. The administration, led by former Food and Drug Administration commissioner Scott Gottlieb, was absolutely correct to crack down on e-cigarette companies marketing nicotine-rich products to teenagers. Keeping young people away from the addictive products and regulating them carefully is vital, given that teens who use e-cigarettes are more likely to start smoking.…  Seguir leyendo »

For a half-century, the ethics of human genetic engineering have been discussed in the abstract. Because the tools to edit DNA didn’t exist, the question was more a thought experiment than a real concern.

Today, though, the conversation has completely changed. There has been a frenzy of excitement around the possibilities of CRISPR-Cas9. The technology, which allows scientists to design proteins that unzip and replace chunks of DNA as they please, makes it possible to edit genes quickly and cheaply. Investors have poured hundreds of millions of dollars into the innovation, which seems to have endless possibilities: making crops more resilient to diseases, designing mosquitoes so they can’t carry malaria — maybe even eliminating diseases among humans by altering the genes we pass on.…  Seguir leyendo »

Thirty years ago, as footage of the Challenger space shuttle explosion streamed across television screens, President Ronald Reagan addressed the nation to reassure citizens that the tragedy would not stop American space exploration.

“It’s all part of the process of exploration and discovery,” Reagan said. That sentiment — that the spirit of discovery is at the core of space exploration — remains central to NASA’s operating mission today, even as the agency’s budget flat-lines and the feasibility of future missions is questioned.

More recently, discussions of the future of space exploration have shifted. Last summer, as the New Horizons spacecraft sped past Pluto to observe the dwarf planet for the first time in history, President Obama lauded the achievement as “a great day for discovery and American leadership.”…  Seguir leyendo »
