The population of corals within Australia’s Great Barrier Reef has plummeted by 50 percent in the last two decades, according to a new study published on Wednesday.
Researchers from the ARC Centre of Excellence for Coral Reef Studies in Queensland, Australia, assessed the colony size of corals in the reef — the world’s largest — between 1995 and 2017, and found a drastic depletion in the population of small, medium and large coral.
“The decline occurred in both shallow and deeper water, and across virtually all species, but especially in branching and table-shaped corals,” study co-author Professor Terry Hughes said of the findings, published in the Royal Society journal.
These specific corals are especially important in providing a habitat for marine life such as fish that inhabit the reef, the researchers said, meaning their loss also results in a decline in reef biodiversity. Despite covering less than 0.1 percent of
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
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
Streaming giant Netflix quietly did away with its 30-day trial in the U.S., according to CNET, just like Disney+, which stopped offering free trials back in June. The U.S. is not the only market where Netflix has decided to end its free trial. The company ended trial periods in Mexico and several other countries as far back as two years ago.
“Free trials are not available, but you can still sign up and take advantage of all Netflix has to offer,” Netflix’s free trial help page now reads. In a statement to CNET, a Netflix spokesperson said the company is currently looking at differen marketing

He is a seventh-degree black belt in Shotokan karate. Any others?
“I do other martial arts, and I hold the rank of black belt in Tae Kwon Do and Ju-jitsu and a couple of other styles. But my base style, my traditional style, is Shotokan karate. At Excel Martial Arts Training Center, we teach traditional karate. We teach Ju-jitsu. We teach sport martial arts, which includes different types of
(Bloomberg) — One Chinese app briefly gave the country’s internet users access to long-banned websites like Facebook Inc. and Google, setting off speculation about the future of Beijing’s censorship practices.
The Tuber browser, backed by Chinese cybersecurity giant 360 Security Technology Inc., appeared to provide the nation’s 904 million online users the ability to legally visit overseas websites and browse foreign social media. Chinese users hailed their newfound ability to peruse content from Youtube videos to Instagram photos without
Looking for investment income? Focusing on yield alone means you’ll miss out on lots of quality companies that pay a smaller dividend, but are still growing and could increase the payout in the future. Looking for companies that check both boxes — dividend payment and growth — can create a powerful compound growth effect over the long term.

In the middle of a pandemic, it reported good news. Here’s why.
This is a story about the three things McDonald’s has done recently that enabled it to report big revenue growth last month, in the midst of a pandemic and economic recession.
The three things? They’re about promotions, predictions, and process — our own new version of the 3 P’s, if you will (as opposed to people process and product). And as you read and learn what McDonald’s has done, you just might find some brilliant inspiration for your business.
First, the big story. McDonald’s said this week that its sales in the United States have bounced back since the start of the pandemic, increasing 4.6 percent over the last three months, against the comparable time period in 2019.
A 3,500 pound great white shark dubbed Nukumi — meaning “Queen of the Ocean” — has been spotted off the coast of Nova Scotia. The massive 50-year-old shark was tagged and released by Ocearch, a research and exploring team that hopes its latest trip out to sea provides new clues to unravel the mysteries of great whites.
“When you see these big females like that that have scars from decades over their lives and multiple mating cycles, you can really kinda see the story of their life unfolding across all the blotches and healed wounds on their body,” team leader Chris Fischer told CBS News’ Jeff Glor. “It really hits you differently thank you would think.”
Tagging Nukumi, one of the largest great white sharks ever seen, was the crowning achievement of Ocearch’s month-long trip off
