Scientists working on Australia's Great Barrier Reef have successfully trialed a new method for freezing and storing coral larvae they say could eventually help rewild reefs threatened by climate change.

Scientists are scrambling to protect coral reefs as rising ocean temperatures destabilize delicate ecosystems. The Great Barrier Reef has suffered four bleaching events in the last seven years including the first ever bleach during a La Nina phenomenon, which typically brings cooler temperatures.

Cryogenically frozen coral can be stored and later reintroduced to the wild but the current process requires sophisticated equipment including lasers. Scientists say a new lightweight "cryomesh" can be manufactured cheaply and better preserves coral. In a December lab trial, the world's first with Great Barrier Reef coral, scientists used the cryomesh to freeze coral larvae at the Australian Institute of Marine Sciences (AIMS). The coral had been collected from the reef for the trial, which coincided with the brief annual spawning window.

"If we can secure the biodiversity of coral … then we'll have tools for the future to really help restore the reefs and this technology for coral reefs in the future is a real game-changer," Mary Hagedorn, senior research scientist at Smithsonian National Zoo and Conservation Biology Institute told Reuters from the AIMS lab.

The cryomesh was previously trialed on smaller and larger varieties of Hawaiian corals. A trial on the larger variety failed.

Trials are continuing with larger varieties of Great Barrier Reef coral.

The trials involved scientists from AIMS, the Smithsonian National Zoo and Conservation Biology Institute, the Great Barrier Reef foundation and the Taronga Conservation Society Australia as part of the Reef Restoration and Adaptation Program.

The mesh technology, which will help store coral larvae at -196C, was devised by a team from the University of Minnesota’s College of Science and Engineering, including Dr. Zongqi Guo and Professor John C. Bischof. It was first tested on corals by researcher Nikolas Zuchowicz.

“This new technology that we’ve got will allow us to do that at a scale that can actually help to support some of the aquaculture and restoration interventions,” said Jonathan Daly of the Taronga Conservation Society Australia.

An American influencer who sparked outrage after posting a video of her snatching a baby wombat from its mother while in Australia apologized on Saturday, saying she had acted out of concern for the young animal’s welfare.
Australian authorities had threatened Sam Jones with deportation after she posted a video on her Instagram account of her running with a wombat joey in her hands from its mother on a roadside at night, The Associated Press reported.
“I ran, not to rip the joey away from its mother, but from fear she might attack me,” Jones, who also uses the name Samantha Strable, posted on social media.
“The snap judgement I made in these moments was never from a place of harm or stealing a joey,” she added.
Prime Minister Anthony Albanese said the video of the young wombat being grabbed was “just an outrage.”
Home Affairs Minister Tony Burke said his department was investigating whether Jones had breached the terms of her visa before she left the country on Friday.
“There’s never been a better day to be a baby wombat in Australia,” Burke said after she left Australia voluntarily.
Burke said he did not expect Jones would apply for an Australian visa again.
The animal appears to be a common wombat, also known as a bare-nosed wombat. It is a protected marsupial found only in Australia.
Montana-based Jones claimed she became “extremely concerned” when she found the two wombats on a road not moving.
“As wombats are so often hit on Australian roads, I stopped to ensure they got off the road safely and didn’t get hit,” Jones said.
“However, as is seen from the video, when I walked up to them, the joey did not move or run off. I was concerned it may have been sick or injured, and made a snap judgement to pick up the joey and see if that was the case,” she added.
An unidentified man laughs as he films Jones saying: “I caught a baby wombat.” They both note the mother’s sounds of aggression.
Animal welfare experts said Jones could have harmed the joey by dangling it by its two forelegs.
Jones said she returned the joey to its mother and ensured they both left the road.
“I have done a great deal of reflection on this situation and have realized that I did not handle this situation as best as I should have,” she said.
“I have learned from this situation, and am truly sorry for the distress I have caused,” she added.
