Editing Your DNA: The Promises and the Risks Ever since scientists discovered they could tamper with genetic material, people have questioned whether the technology is too powerful and too dangerous to unleash on the world. Now, just in the last three years, new methods of DNA engineering are so precise, so fast, and so inexpensive, that it’s bringing this technology within reach of more scientists and entrepreneurs than ever before. Given the fraught debate over genetically modified foods, how will society deal with the sci-fi -- like prospects of species-specific bio-weapons, invasive mutant crops, or enhancing genes for qualities like beauty and intelligence?
Nuclear crisis on the Korean Peninsula slowly coming to a head North Korea did not conduct a nuclear test this weekend, but it did show apparent progress in developing a missile that that could strike the United States. The Trump Administration says it has lost its "strategic patience." We hear what that might -- or might not -- mean for North Korea, China and the prospects for diplomacy.
Will the march for science politicize objective research? Protesters are gathering all over the country for tomorrow's Earth Day March for Science. Since President Trump has proposed massive cuts in basic scientific research, will the movement be perceived as partisan politics — whether scientists themselves like it or not?
Mixed Messages from US diplomats on the new hard line on Syria Since President Trump's surprise retaliation against Syria's use of chemical weapons, Bashar al-Assad has used the same airport to launch conventional attacks on his own people. It's not clear what the US, its allies — or Vladimir Putin's Russia -- plan to do now.
