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.

UK core pay growth strongest in nearly 11 years, but jobs growth slows

  • Core earnings have increased by 3.6 percent annually, beating the median forecast of 3.5 percent
  • The unemployment rate fell by 51,000 to just under 1.3 million

LONDON: British wages, excluding bonuses, rose at their fastest pace in more than a decade in the three months to May, official data showed, but there were some signs that the labor market might be weakening. Core earnings rose by an annual 3.6 percent, beating the median forecast of 3.5 percent in a Reuters poll of economists. Including bonuses, pay growth also picked up to 3.4 percent from 3.2 percent, stronger than the 3.1 percent forecast in the poll. Britain’s labor market has been a silver lining for the economy since the Brexit vote in June 2016, something many economists attribute to employers preferring to hire workers that they can later lay off over making longer-term commitments to investment. The pick-up in pay has been noted by the Bank of England which says it might need to raise interest rates in response, assuming Britain can avoid a no-deal Brexit. Tuesday’s data showed the unemployment rate remained at 3.8 percent as expected, its joint-lowest since the three months to January 1975. The number of people out of work fell by 51,000 to just under 1.3 million. But the growth in employment slowed to 28,000, the weakest increase since the three months to August last year and vacancies fell to their lowest level in more than a year. Some recent surveys of companies have suggested employers are turning more cautious about hiring as Britain approaches its new Brexit deadline of Oct. 31. Both the contenders to be prime minister say they would leave the EU without a transition deal if necessary. A survey published last week showed that companies were more worried about Brexit than at any time since the decision to leave the European Union and they planned to reduce investment and hiring. “The labor market continues to be strong,” ONS statistician Matt Hughes said. “Regular pay is growing at its fastest rate for nearly 11 years in cash terms and its quickest for over three years after taking account of inflation.” The BoE said in May it expected wage growth of 3 percent at the end of this year.
