Dangerous science in China 　 　　　　　　　　 1. A Chinese researcher stunned the medical world by announcing that he had altered the DNA of embryos, resulting in the births of twin girls with enhanced protection against infection. In the ensuing uproar, doctors, scientists, ethicists and governments denounced the project, demanded an investigation and the suspension of more work by the scientist until its effects and implications are better understood. Gene editing may be inevitable, but this is not the way to do science. But projects of this nature are likely to become ever more common, and the science profession and society as a whole must better prepare for this grim future. 2. On paper, He Jiankui looks like an ordinary scientist. He received a PhD in biophysics from Rice University and did postdoctoral research at Stanford before returning to China. He, who was according to his Stanford advisor “super bright” and “at the cutting edge of trying to apply new technologies to biology,”

1 WASHINGTON — Humans are transforming Earth’s natural landscapes so dramatically that as many as one million plant and animal species are now at risk of extinction, posing a dire threat to ecosystems that people all over the world depend on for their survival, a sweeping new United Nations assessment has concluded.        2 The 1,500-page report, compiled by hundreds of international experts and based on thousands of scientific studies, is the most exhaustive look yet at the decline in biodiversity across the globe and the dangers that creates for human civilization. A summary of its findings , which was approved by representatives from the United States and 131 other countries, was released Monday in Paris. The full report is set to be published this year.                                                                                      3 Its conclusions are stark. In most major land habitats, from the savannas of Africa to the rain forests of South America, the average abu

Tokyo Olympics offer ‘second-chance’ lottery for Japan fans Tokyo Olympic organizers are putting “a few hundred-thousand” tickets into a lottery next month for Japan residents who were shut out when results of the first lottery were announced in June. The new “second-chance” lottery is being organized on short notice because of unprecedented demand in Japan. Demand is believed to be at least 10 times over supply — probably more. It means few in the host country who want tickets can get them. Organizing committee spokesman Masa Takaya on Friday said 3.22 million tickets were sold to Japan residents in the first lottery. He said more than 90 percent of applicants bought the tickets that they were awarded. He said only the unsold tickets would be those offered in the next round. Tokyo organizers are trying to satisfy the Japanese public. But there simply aren’t enough Olympic tickets to go around with demand soaring. Authorized Ticket Resellers — the Olympic agents contracted to

Unrivaled demand causes turmoil Overwhelmed by unprecedented demand, Tokyo Olympic organizers said Thursday they hope to run another ticket lottery next month for residents of Japan who got nothing the first time. Millions of Japanese were let down last month when they came away empty-handed in a lottery for next year’s Olympics. The bad news is that — despite a last-minute change of plans — most applicants will be disappointed again. There simply aren’t enough Olympic tickets to go around with demand soaring in Japan and elsewhere as Authorized Ticket Resellers — the Olympic agents contracted to sell tickets outside Japan — have also opened sales worldwide. Demand is being driven by the 35 million people who live in Greater Tokyo, and is in sharp contrast to the last Olympics in Rio de Janeiro where tickets were being given away or went unsold. “The demand from the general public indeed exceeded our expectations,” Tokyo spokesman Masa Takaya told The Associated Press.
