Indonesia's sweeping restructuring of science sector faces criticism

Indonesia's government is facing criticism from some top scientists and lawmakers that a sweeping restructuring bringing together the country's leading science and technology institutes could undermine research efforts. The policy will see half a dozen science, technology and research institutes integrated into a National Research and Innovation Agency (BRIN), a move the government hopes will improve access to resources and funding, and boost competitiveness.

Son calls father's pig-heart transplant a miracle of science

The son of a transplant recipient who was implanted with a genetically modified pig heart in a first-of-its-kind surgery, called his father's procedure "a miracle." The surgery, performed by a team at the University of Maryland Medicine on Jan. 7, is among the first to demonstrate the feasibility of a pig-to-human heart transplant, a field made possible by new gene editing tools.

Anemia in astronauts could be a challenge for space missions

The next "giant leap" for humans may be a trip to Mars, but having enough oxygen-carrying red blood cells for the journey might present a challenge, new research suggests. Even space tourists lining up for short trips might have to stay home if they are at risk for anemia, or red blood cell deficiency, researchers said.

NASA begins process of bringing new space telescope into focus

NASA on Wednesday embarked on a months-long, painstaking process of bringing its newly launched James Webb Space Telescope into focus, a task due for completion in time for the revolutionary eye in the sky to begin peering into the cosmos by early summer. Mission control engineers at NASA's Goddard Space Flight Center in Greenbelt, Maryland, began by sending their initial commands to tiny motors called actuators that slowly position and fine-tune the telescope's principal mirror.
