MH370: Two new 'pings' boost confidence that missing plane could be found

April 9, 2014

MH370Sydney/Perth, Apr 9: Australian officials said on Wednesday that two new "ping" signals had been detected in the search for Malaysia Airlines Flight MH370, boosting confidence after more than a month of fruitless searching for the missing jetliner.

The signals, which could be from the plane's black box recorders, bring to four the number of overall "pings" detected in recent days within the search area by a US Navy "Towed Pinger Locator"(TPL).

Angus Houston, head of the Australian agency coordinating the search, struck an optimistic tone when announcing the information, but urged caution as the task of searching the remote Indian Ocean region remained enormous.

"I believe we are searching in the right area but we need to visually identify aircraft wreckage before we can confirm with certainty that this is the final resting place of MH370," Houston told reporters in Perth.

"I'm now optimistic that we will find the aircraft, or what is left of the aircraft, in the not too distant future."

The black boxes record cockpit data and may provide answers about what happened to the plane, which was carrying 227 passengers and 12 crew when it vanished on March 8 and flew thousands of kilometres off its Kuala Lumpur-to-Beijing route.

But the batteries in the beacons have already reached the end of their 30-day expected life, making efforts to swiftly locate them all the more critical.

Authorities say evidence suggests the plane was deliberately diverted by someone familiar with the aircraft, but have not ruled out mechanical problems.

Analysis of satellite data led investigators to conclude the Boeing 777 came down in a remote area of the Indian Ocean, some 2,261 kms (1,405 miles) northwest of the Australian city of Perth.

Fresh pings but in a large area

Up to 11 military aircraft, four civilian aircraft and 14 ships were planned to carry on Wednesday with a massive search that has, so far, yielded frustratingly little concrete information.

On the weekend, the sophisticated US Navy TPL picked up what officials said were two signals consistent with black box locator beacons — the first for more than two hours and the second for about 13 minutes.

On Wednesday, Houston said that another ping was detected on Tuesday afternoon and lasted five minutes, 25 seconds, while a second was picked up on Tuesday night and lasted seven minutes. That brings to four the number of pings found in the area.

But two US Navy officers told Reuters on Wednesday that while the pings had been found within a 1,300 square kilometre area, they were not confident that they represented reoccurances of the same signal.

"I'd say they are separate acoustic events," said US Navy Captain Mark Matthews, citing the fact that the pings are not close together.

"There has been variability in the geographic position which leads me to be less optimistic than I would be if I could consistently reacquire the signal so that I have a nice, small geographic area to focus the autonomous under water vehicle search on," he added.

An autonomous underwater vehicle named Bluefin-21 is onboard the Ocean Shield and could be sent to look for wreckage on the sea floor once intelligence narrows the search area.

The potential search area is currently about 4.5 km (2.8 miles) deep, the outer reach of the Bluefin's range.

A race against time

Although the batteries in the black box recorders are thought to have a lifespan of roughly 30 days, officials have said they can last for as long as two weeks beyond that time.

That meant the search was becoming even more of a race against time than it has been up to now, said Houston.

"I mean, we are looking at this stage for transmissions that are probably weaker than they would have been early on because the batteries of both devices are passed their use-by date and they will very shortly fail," he said.

Despite the new signals being detected, Houston insisted that search teams should exhaust the capability of planes and vessels before deploying underwater vehicles.

"Bear in mind, that the time spent on the surface we're covering six times more area and any given time than we'll be able to do when we go underwater," Houston said.

"So with the batteries likely to fade or fail very shortly, we need to get as much positional data as we can so that we can define a very small search area."

For the first time in the 15 years of the Global Risks Report, the climate change and environment risk has occupied all the top five slots.

According to the 15th edition of the World Economic Forum's (WEF) Global Risks Report, the top five risks in terms of likelihood are extreme weather, climate action failure, natural disasters, biodiversity loss and human-made environmental disasters. They all fall in the one category of climate change and related environmental disasters.

WEF President Borge Brende said the world was feeling long-mounting and interconnected risks.

The report also points to how citizens are protesting across the world as discontent rises with failed systems that are creating inequality. The citizens' discontent had hardened with systems that had failed to promote advancement, it said.

"Disapproval of how governments are addressing profound economic and social issues has sparked protests throughout the world, potentially weakening the ability of governments to take decisive action should a downturn occur. Without economic and social stability, countries could lack the financial resources, fiscal margin, political capital or social support needed to confront key global risks," it said.

Listing the grim scenario, Borge said the global economy was faced with "synchronised slowdown", the past five years had been the warmest on record and cyber attacks were expected to increase this year.

The report warns that while the myriad risks were rising, time was running out on how to prevent them.

Borge said the growing palpability of shared economic, environmental and societal risks indicated that the horizon had shortened for preventing "or even mitigating" some of the direst consequences of global risks.

"It's sobering that in the face of this development, when the challenges before us demand immediate collective action, fractures within the global community appear to only be widening," he said.

The report points to grave concern about the consequences of continued environmental degradation, including the record pace of species decline.

Pointing to an unsettled geopolitical environment, the report said today's risk landscape was one in which new centres of power and influence were forming and old alliance structures and global institutions were being tested.

"While these changes can create openings for new partnership structures in the immediate term, they are putting stress on systems of coordination and challenging norms around shared responsibility. Unless stakeholders adapt multilateral mechanisms for this turbulent period, the risks that were once on the horizon will continue to arrive," it said.

Calling it a "an unsettled world", the WEF report notes that powerful economic, demographic and technological forces were shaping a new balance of power. "The result is an unsettled geopolitical landscape in which states are increasingly viewing opportunities and challenges through unilateral lenses," it said.

"What were once givens regarding alliance structures and multilateral systems no longer hold as states question the value of long-standing frameworks, adopt more nationalist postures in pursuit of individual agendas and weigh the potential geopolitical consequences of economic decoupling. Beyond the risk of conflict, if stakeholders concentrate on immediate geo-strategic advantage and fail to re-imagine or adapt mechanisms for coordination during this unsettled period, opportunities for action on key priorities may slip away," the WEF said.

In a chapter on risks to economic stability and social cohesion, it said a challenging economic climate might persist this year and members of the multi-stakeholder community saw "economic confrontations" and "domestic political polarisation" as the top risks in 2020.

The report also warned of downward pressure on the global economy from macroeconomic fragilities and financial inequality. These pressures continued to intensify in 2019, increasing the risk of economic stagnation.

Low trade barriers, fiscal prudence and strong global investment, once seen as fundamentals for economic growth, are fraying as leaders advance nationalist policies. The margins for monetary and fiscal stimuli are also narrower than before the 2008-2009 financial crisis, creating uncertainty about how well countercyclical policies will work.

The strategic partners for the WEF report included Marsh & McLennan and Zurich Insurance Group. The academic advisers were National University of Singapore, Oxford Martin School, University of Oxford and Wharton Risk Management and Decision Processes Center, University of Pennsylvania.

May 6: In a first, a Pakistani Hindu youth has become the first person from the minority community to join the Pakistan Air Force.

Rahul Dev has been recruited as a General Duty Pilot Officer, the Pakistan Air Force (PAF) said in a tweet.

Dev hails from Tharparkar district of Sindh province.

Sharing the picture of the young man, the PAF recently tweeted, "Good news during #COVID19 tense situation. Thar rocked again...Congratulations #RahulDev who hails from very remote village of Tharparkar has been selected as GD Pilot in #PAF."

Though Dev's exact age is not known, those inducted in PAF at his level are often around 20.

The official Radio Pakistan on Wednesday said it is "for the first time in Pakistan's history" that a Hindu youth has been recruited as a general duty pilot officer in PAF.

The Express Tribune in a report published on Wednesday said the induction showed that the PAF was breaking barriers.

Last year, Kainat Junaid became the first woman from Khyber-Pakthunkhwa province to have been selected for fighter pilot training.

Junaid not only secured the top position in PAF's test for General Duty Pilot, but also became Pakistan’s first female fighter pilot to serve the country alongside her father.

Her father Ahmed Junaid is a Squadron Leader in the PAF.

Melbourne, Apr 10: Scientists have identified six drug candidates from more than 10,000 compounds that may help treat COVID-19.

The research, published in the journal Nature, tested the efficacy of approved drugs, drug candidates in clinical trials and other compounds.

"Currently there are no targeted therapeutics or effective treatment options for COVID-19," said Professor Luke Guddat from the University of Queensland in Australia.

"In order to rapidly discover lead compounds for clinical use, we initiated a programme of high-throughput drug screening, both in laboratories and also using the latest computer software to predict how different drugs bind to the virus," Guddat said.

The project targeted the main COVID-19 virus enzyme, known as the main protease or Mpro, which plays a pivotal role in mediating viral replication, the researchers said.

This makes it an attractive drug target for this virus, and as people don't naturally have this enzyme, compounds that target it are likely to have low toxicity, they said.

"We add the drugs directly to the enzyme or to cell cultures growing the virus and assess how much of each compound is required to stop the enzyme from working or to kill the virus. If the amount is small, then we have a promising compound for further studies," said Guddat.

After assaying thousands of drugs, researchers found of the six that appear to be effective in inhibiting the enzyme, one is of particular interest.

"We're particularly looking at several leads that have been subjected to clinical trials including for the prevention and treatment of various disorders such as cardiovascular diseases, arthritis, stroke, atherosclerosis and cancer," Guddat said.

Researchers said compounds that are already along the pipeline to drug discovery are preferred, as they can be further tested as antivirals at an accelerated rate compared to new drug leads that would have to go through this process from scratch.

"With continued and up-scaled efforts we are optimistic that new candidates can enter the COVID-19 drug discovery pipeline in the near future," Guddat said.
