NASA's InSight lands on Mars to peer into planet's deep interior

NASA's InSight spacecraft, the first robotic lander designed to study the deep interior of a distant world, touched down safely on the surface of Mars on Monday with instruments to detect planetary seismic rumblings never measured anywhere but Earth. Engineers at the Jet Propulsion Laboratory (JPL) near Los Angeles burst into cheers, applause and hugs as they received signals confirming InSight's arrival on Martian soil - a vast, barren plain near the planet's equator - shortly before 3 p.m. EST.

In open letter, scientists in China say baby gene editing 'crazy'

More than 100 scientists, most of them in China, have condemned as "crazy" and unethical a geneticist's claim that he altered the genes of twin girls born this month to create the first gene-edited babies. In an open letter circulating online, the scientists said the use of CRISPR-Cas9 technology to edit the genes of human embryos was risky, unjustified and harmed the reputation and development of the biomedical community in China.
