Australia unveils starfish-killing robot to protect Barrier Reef

SYDNEY: A robot submarine able to hunt and kill the predatory crown-of-thorns starfish devastating the Great Barrier Reef was unveiled by Australian researchers on Friday.
Scientists at Queensland University of Technology (QUT) said the robot, named the RangerBot and developed with a grant from Google, would serve as a "robo reef protector" for the vast World Heritage site off Australia's northeastern coast.
The RangerBot has an eight-hour battery life and computer vision capabilities allowing it to monitor and map reef areas at scales not previously possible.
"RangerBot is the world's first underwater robotic system designed specifically for coral reef environments, using only robot-vision for real-time navigation, obstacle avoidance and complex science missions," said Matthew Dunbabin, the QUT professor who unveiled the submarine.
"This multi-function ocean drone can monitor a wide range of issues facing coral reefs including coral bleaching, water quality, pest species, pollution and siltation."
Software will also enable the bot to detect crown-of-thorns starfish, which eat coral, and "instigate an injection which is fatal" to the predators, he said, adding that the injection is harmless for other reef creatures.
The starfish have proliferated in recent times due to pollution and agricultural runoff.
The Great Barrier Reef, about the size of Japan or Italy, is reeling from two straight years of bleaching as sea temperatures rise because of climate change.
Experts have warned that the 2,300-kilometre (1,400-mile) long area could have suffered irreparable damage due to the combined effects of bleaching, damage from agricultural runoff and the impact of the crown-of-thorns starfish.

Barclays payments to Qatar would have been ‘unacceptable’ to market, London court hears

  • The UK Serious Fraud Office alleges that four bankers agreed to pay £322 million in secret fees to Qatar
  • It is claimed that Barclays agreed to pay Qatar more than double the standard 1.5 percent investment commission and hid this from other investors

LONDON: Former Barclays Chairman Marcus Agius could not remember if he was told the bank was paying higher fees to Qatar than other investors during an £11.2 billion ($14.6 billion) fundraising in the depths of the 2008 financial crisis, a London court heard on Tuesday.

However he said that paying such commission to one set of underwriters and not the other would have been “unacceptable to the market.” Agius is not accused of any wrongdoing.

He was the first witness to testify in the trial of four former Barclays executives, who include the then CEO John Varley.

“I would have wanted to understand why it would’ve been necessary,” he told the court.

The UK Serious Fraud Office alleges that the four bankers agreed to pay £322 million in secret fees to Qatar.

During the fraud trial — which began in January — the prosecution told the court that the then Qatari Prime Minister Sheikh Hamad bin Jassim demanded a personal fee for investing in Barclays.

It is claimed that Barclays agreed to pay Qatar more than double the standard 1.5 percent investment commission and hid this from other investors by making the payments through what prosecutors alleged were bogus Advisory Services Agreements, or ASAs, Southwark Crown Court heard.

Agius also told the court that he feared resignations from the board in 2008.

“Any one of them might have said, ‘This wasn’t what I signed up for, how do I get out of here?,’” he said.

“I’m clear that in June 2008 we at Barclays did not anticipate how much worse things were going to get. I don’t think we thought it was going to go as badly as it ultimately did.”
