Everyone can play a part in conserving Australia’s World Heritage-listed Great Barrier Reef — ScienceDaily

Many Australians do not know what they can individually do to make a difference to the health of the World Heritage-listed Great Barrier Reef (GBR), according to a survey led by QUT researchers.

The researchers found most Australians are not making a connection between climate change and reef health and say there is more individuals could do on this front, both in the home and to influence government policies.

Senior Research Fellow Dr Angela Dean conducted the online survey of 4,285 Australians with Professor Kerrie Wilson, Director of QUT’s Institute for Future Environments, and Dr Robyn Gulliver from the University of Queensland.

The resulting paper, “Taking action for the Reef?” — Australians do not connect Reef conservation with individual climate-related actions, has been published in Conservation Letters: a journal of the Society for Conservation Biology.

“While there are many threats to reef health, including poor water quality stemming from

Baby Coral Deaths Threaten the Great Barrier Reef’s Recovery

(Bloomberg) — The mass death of young and old corals in Australia’s Great Barrier Reef is threatening the recovery of the largest living structure on Earth.

An undated handout photo received from the ARC Centre of Excellence Coral Reef Studies on October 14, 2020 shows a damaged part of the Great Barrier Reef – the vast World Heritage-listed reef off Australia’s northeastern coast.

The bleaching of corals off Australia’s northeastern coast due to ocean warming and acidification is happening across all species and to specimens of all ages, according to a new study that analyzed coral demographics. The study, led by Andy Dietzel at the ARC Centre of Excellence for Coral Reef Studies in Australia, confirmed the Great Barrier Reef lost half its corals between 1995 and 2017.

“We measured changes in colony sizes because population studies are important for understanding demography and the corals’ capacity to

Boom Supersonic wants you to break the sound barrier

Someday ordinary people might fly at supersonic speeds in this. 


Boom Supersonic

Boom Supersonic on Wednesday unveiled what it hopes to be the first step in letting ordinary people fly at supersonic speeds again. The XB-1 that rolled out at an event in Colorado won’t carry passengers, but it’ll serve as a demonstration aircraft to test the company’s technologies.

“We have begun to pave the path of a mainstream supersonic future,” said CEO Blake Scholl. “Today we stand on the precipice of a new age of travel.” 

The 71-foot XB-1 will use three General Electric engines with 12,000 pounds of thrust. As with the Concorde, a long pointy nose will obscure the view of the runway from the cockpit during landing, but cameras will take the place
