Costa Rica researchers to trial coronavirus treatment from horse antibodies

Researchers in Costa Rica are due to begin trials of an inexpensive coronavirus treatment based on antibodies taken from horses injected with the SARS-Cov-2, the virus that causes COVID-19, according to scientists. Developed by University of Costa Rica's Clodomiro Picado Institute (ICP), the equine antibodies medication is to be tested on 26 patients from mid-September, Roman Macaya, president of the Social Security Fund that manages public health centers, told Reuters.

Reusable Chinese spacecraft lands successfully: state media

An experimental reusable spacecraft launched into orbit two days ago by China has successfully returned to a designated site on Sunday, marking a breakthrough that could lead to cheaper round-trips to space, the official Xinhua News Agency reported. The mission had been kept low-key, and state media had yet to publish photographs or video footage of both the launch and landing of the spacecraft. No details were given on the techologies that had been tested.
