Mass bleaching events offer low prospect of recovery for Great Barrier Reef

Mass bleaching events offer zero prospect of recovery for Great Barrier Reef

Mass bleaching events occurred just twelve months apart offer zero prospect of recovery for the Great Barrier Reef in north Queensland, scientists have warned.

The Great Barrier Reef suffered two consecutive massive coral bleaching events, in 2016 and 2017. A team of scientists from the Australian Research Council’s Centre of Excellence for Coral Reef Studies conducted aerial surveys of the structure, and found that the bleaching events damaged a 1,500km stretch of the reef.

Cyclone Debbie impacts Great Barrier Reef: Report

Cyclone Debbie makes devastating blow to Great Barrier Reef

After suffering back-to-back severe coral bleaching, the Great Barrier Reef has had to cope with another devastating blow — Cyclone Debbie. Ferocious winds moving at speeds of up to 260 kilometer per hour tore through the Whitsunday Islands and made landfall at Airlie Beach. Local researchers and reporters went underwater to examine the destruction caused by the cyclone.

The cyclone snapped off branches and lifted up and threw aside massive pieces of coral. Local tour operators portrayed a disheartening picture of the broken reef.

Coral bleaching affected two-thirds of Australia’s Great Barrier Reef: Study

Coral bleaching affected two-thirds of Australia’s Great Barrier Reef: scientists say

New aerial surveys have confirmed that back-to-back coral bleaching events have affected more than two-thirds of Australia’s Great Barrier Reef.

A team of scientists with the Centre of Excellence for Coral Reef Studies at the Australian Research Council conducted the surveys, and scored bleaching at 800 individual coral reefs across 8,000 kilometers at the world’s biggest living structure.

The results proved that two mass bleaching events that took placed in the recent years have affected a 1,500-kilometer stretch, leaving merely the southern part of the reef unscathed.

FRBs really coming from outer space: Research

FRBs really coming from outer space: scientists say

The mysterious pulses of radio energy or super-bright flashes called fast radio bursts (FRBs) have been perplexing scientists for the last many years. But, now they are sure at least about one thing, i.e., those pulses are originating from outer space.

Lasting just a few milliseconds, FRBs are around a billion times more luminous than even our Sun, and these flashes seem to be traveling across at really fast speeds covering vast distances.

ANU crowdsources ‘Planet 9’ search

ANU crowdsources ‘Planet 9’ search

Seeking help from public to find the mooted-but-not-yet-discovered “Planet 9,” the Australian National University (ANU) has decided to crowdsource the search.

After years of dismissing the idea that another planet termed as Planet 9 exists beyond Pluto was revived in January last year when CalTech scientists claimed that they claimed that they detected an undiscovered planet in the so-called Kuiper Belt.

In March 2016, Michelle Bannister of the SETI Institute revealed a formerly-undocumented Kuiper Belt Object that partly matched the CalTech scientists’ predictions.

Debate over Great Barrier Reef’s decline continues

Debate over Great Barrier Reef’s death continues

Earlier this month, the Great Barrier Reef Marine Park Authority (GBRMPA) of Australia warned that numerous species in the popular reef would struggle to fully recover as it is experiencing an unprecedented mass coral bleaching for the second year in a row.

Most scientists believe that reefs across the globe, including Australia’s Great Barrier Reef, are dying due to global warming.

However, some coral reef experts and Republicans in particular argue that there is no strong evidence showing that manmade global warming is responsible for reef damages.

Scientists struggling to prevent total wipeout of crucial coral reefs

Scientists struggling to prevent total wipeout of crucial coral reefs

Following a recent aerial survey of Australia’s Great Barrier Reef, scientists are trying to find new ways to prevent a possible total wipeout of the coral reefs.

The aerial survey showed that the Great Barrier Reef is experiencing widespread coral bleaching for the second year in a row, indicating that water temperatures remained too warm to allow corals to recover from last year’s bleaching.

Scientists warned that several coral species are now more susceptible to bleaching after more than twelve months of continued above-average ocean temperatures.

Star and black hole spotted in tight orbital dance

Star, black hole spotted in tight orbital dance

With the help of the Australia Telescope Compact Array, astronomers have discovered a star orbiting a black hole at merely 2½ times the distance between the Earth and Moon. Astronomers have limited information about black holes and the way they function. Many questions have still remained unanswered regarding black holes.

While the star is still at a distance of one million kilometers for the black hole, it is very close in astronomical terms. No star ever before has been discovered so close to a black hole.

Great Barrier Reef experiencing second year of mass coral bleaching

Great Barrier Reef experiencing second year of mass coral bleaching

Several species in Australia’s Great Barrier Reef would struggle to fully recover as the reef is experiencing an unprecedented second year of mass coral bleaching, scientists have warned.

Last year during March and April, the 1,400-mile (2,300-kilometre) reef experienced its most severe coral bleaching on record.

The Great Barrier Reef Marine Park Authority (GBRMPA) said in statement that the reef is once again experiencing coral bleaching due to warmer water temperature. The statement followed an aerial survey off the country’s eastern coast on Thursday.

Australian Researchers Find Clues for Early Detection of Lung Cancer

Australian Researchers Find Clues for Early Detection of Specific Form of Lung Cancer

Australian researchers have found an innovative way of early detection of lung cancer and the process can bring a major change in detection of lung cancer by checking for ‘origin cell’. The research team at Walter and Eliza Hall Institute in Melbourne has found the cell that they term as the reason behind lung cancer among 30 percent of patients. The technique could help smokers and ex-smokers as basal stem cells in the airway of the lungs hold the key for early detection.
