Science News Roundup: Chile's ALMA seeks to double capacity in a decade after a slow re-opening; Ghana startup strives for greater African representation in cancer research and more

Less than a week after its launch from the Cape Canaveral U.S. Space Force Base in Florida, the CST-100 Starliner autonomously separated from the space station at 2:36 p.m. EDT (1836 GMT) to embark on a five-hour-plus return flight. Bacteria with antibiotic resistant genes discovered in Antarctica, scientists say Bacteria in Antarctica have been discovered with genes that give them natural antibiotic and antimicrobial resistance and have the potential to spread out of the polar regions, according to scientists in Chile.

Following is a summary of current science news briefs.

Chile's ALMA seeks to double capacity in a decade after a slow re-opening

Now that Chile's ALMA Observatory is running at full force after the COVID-19 pandemic caused its first shutdown, its director is hoping to double its capacity to better understand black holes. "We're looking to enhance the capabilities of ALMA over the next 10 years," said Sean Dougherty, ALMA's director.

Ghana startup strives for greater African representation in cancer research

In the open-air kitchen of a small research clinic in Ghana's capital, Accra, pathologist Kafui Akakpo carefully carved a piece of cancerous breast tissue into a sample smaller than a matchbox. Hundreds of other samples bobbed around him in plastic jars of formaldehyde, but this one would soon travel across town to Yemaachi Biotech, Ghanaian research, and diagnostics startup that Akakpo thinks could change African cancer studies forever.

Uncrewed Boeing Starliner capsule undocks from the space station for return to Earth

The uncrewed new Boeing Starliner capsule undocked from the International Space Station on Wednesday to begin a descent back to Earth from its first journey to the outpost, nearing the end of a high-stakes test flight as NASA's next vehicle for carrying humans to orbit. Less than a week after its launch from the Cape Canaveral U.S. Space Force Base in Florida, the CST-100 Starliner autonomously separated from the space station at 2:36 p.m. EDT (1836 GMT) to embark on a five-hour-plus return flight.

Bacteria with antibiotic-resistant genes discovered in Antarctica, scientists say

Bacteria in Antarctica have been discovered with genes that give them natural antibiotic and antimicrobial resistance and have the potential to spread out of the polar regions, according to scientists in Chile. Andres Marcoleta, a researcher from the University of Chile who headed the study in the Science of the Total Environment journal in March, said that these "superpowers" which evolved to resist extreme conditions are contained in mobile DNA fragments that can easily be transferred to other bacteria.

Boeing Starliner capsule returns to Earth, capping key uncrewed test mission

Boeing Co's Starliner astronaut capsule returned from the International Space Station and landed in New Mexico on Wednesday, capping a high-stakes test flight as NASA's next vehicle for carrying humans to orbit. Less than a week after its launch from the Cape Canaveral U.S. Space Force Base in Florida, the CST-100 Starliner capsule plunged through Earth's atmosphere Wednesday evening ahead of a parachute-assisted descent over the desert of White Sands Space Harbor, New Mexico. It touched down on time at 6:49 p.m. EDT (2249 GMT).

ESA does not anticipate Russian withdrawal from ISS

The European Space Agency does not expect Russia to terminate the joint operation of the International Space Station (ISS) with the West, ESA Director-General Josef Aschbacher told Reuters on Wednesday. The ISS, the largest artificial object in space, has been continuously occupied since November 2000, operated by a U.S.-Russian-led international consortium of five space agencies from 15 countries.
