Suspected debris from missing Malaysian jet may have sunk: Australia

March 21, 2014

Debris_sunkPerth/Kuala Lumpur, Mar 21: The international team hunting for Malaysia Airlines Flight MH370 in the southern Indian Ocean has not turned up anything so far, and Australia's deputy prime minister said the suspected debris may have sunk.

Aircraft and ships have renewed a search in the Andaman Sea between India and Thailand, going over areas that have already been exhaustively swept to find some clue to unlock one of the most inexplicable mysteries in modern aviation.

The Boeing 777 went missing almost two weeks ago off the Malaysian coast with 239 people aboard. There has been no confirmed sign of wreckage but two objects seen floating deep south in the Indian Ocean were considered a credibe lead and set off a huge hunt on Thursday.

Australian authorities said the first aircraft to sweep treacherous seas on Friday in an area about 2,500km (1,500 miles) southwest of Perth was on its way back to base without spotting the objects picked out by satellite images five days ago.

"Something that was floating on the sea that long ago may no longer be floating," Deputy prime minister Warren Truss told reporters in Perth. "It may have slipped to the bottom."

But the search is continuing and and Australian, New Zealand and US aircraft would be joined by Chinese and Japanese planes over the weekend.

"It's about the most inaccessible spot that you can imagine on the face of the Earth, but if there is anything down there, we will find it," Australian Prime Minister Tony Abbott told reporters in Papua New Guineau, where he is on a visit.

"Now it could just be a container that's fallen off a ship. We just don't know, but we owe it to the families, and the friends and the loved ones to do everything we can to try to resolve what is as yet an extraordinary riddle."

India said it was sending two aircraft, a Poseidon P-8I maritime surveillance aircraft and a C-130 Hercules transporter, to join the hunt in the southern Indian Ocean. It is also sending another P-8I and four warships to search in the Andaman Sea, where the plane was last seen on military radar on March 8.

In New Delhi, officials said the search in areas around the Andaman island chain was not at the request of Malaysian authorities coordinating the global search for the airliner.

"All the navies of the world have SAR regions," said Capt DK Sharma, an Indian Navy spokesman, referring to search and rescue regions. "So we're doing it at our own behest.

"We're doing it on our own because the Malaysian plane is still missing."

Investigators suspect Flight MH370, which took off from Kuala Lumpur for Beijing shortly after midnight on March 8, was deliberately diverted thousands of miles from its scheduled path. They say they are focusing on hijacking or sabotage but have not ruled out technical problems.

The search for the plane also continues in other regions, including a wide arc sweeping northward from Laos to Kazakhstan.

In the Indian Ocean, three Australian P-3 Orions joined a high-tech US Navy P-8 Poseidon and a civilian Bombardier Global Express jet to search the 23,000 square km (8,900 sq mile) zone, the Australian Maritime Safety Authority said.

A Norwegian merchant ship, the Hoegh St. Petersburg, was diverted to the area on Thursday and was still searching there and another vessel would arrive later on Friday.

China's icebreaker for Antarctic research, Xuelong, or Snow Dragon, will set off from Perth to search the area, Chinese state news agency Xinhua cited maritime authorities as saying. Up to five more Chinese ships were steaming towards the search zone from across the Indian Ocean, Xinhua reported.

Australian authorities said they had not asked for the ships to search the area. About two-thirds of the missing plane's passengers were Chinese nationals.

Studying satellites

There have been many false leads and no confirmed wreckage found from Flight MH370 since it vanished off Malaysia's east coast less than an hour after taking off.

There has also been criticism of the search operation and investigation, as more than two dozen countries scramble to overcome logistical and diplomatic hurdles.

Investigators piecing together patchy data from military radar and satellites believe that, minutes after its identifying transponder was switched off as it crossed the Gulf of Thailand, the plane turned sharply west, re-crossing the Malay Peninsula and following an established route towards India.

What happened next is unclear, but faint electronic "pings" picked up by one commercial satellite suggest the aircraft flew on for at least six hours.

A source with direct knowledge of the situation said that information gleaned from the pings had been passed to investigators within a few days, but it took Malaysia more than a week to narrow the search area to two large arcs - one reaching south to near where the potential debris was spotted, and a second crossing to the north into China and central Asia.

Feb 4: Americans on Monday kicked off the first vote of the 2020 presidential race as the midwestern state of Iowa began its caucuses, the closely-watched first step in deciding which Democrat will face incumbent Donald Trump in November's election.

The two frontrunners, left-wing Senator Bernie Sanders and former Vice President Joe Biden face a key test in the sparsely populated state, with a handful of others looking to make their mark to give their campaigns momentum.

The Iowa vote is a critical early look at the viability of the 11 Democratic candidates still in the race - even though just 41 Iowa delegates are up for grabs, a fraction of the 1,991 needed to secure the party nomination in July.

Iowa Democrats filed into nearly 1,700 caucus sites - schools, libraries, churches, mosques and meeting halls with Sanders and Biden in the lead in the state, followed by former South Bend, Indiana mayor Pete Buttigieg and Senator Elizabeth Warren, who is also on the left of the party.

But polling has fluctuated and Iowa's quirky caucus system - where voting is not by secret ballot but by public declaration for a candidate - makes the night hard to predict.

Luke Elzinga, a volunteer for Sanders, appeared early at Lincoln High School in Des Moines which was converted into a caucus location.

"I think he really inspires a lot of young people, a lot of disaffected voters who might not otherwise turn out," Elzinga, 28, told AFP news agency shortly before the caucusing began.

"And so I think he's the best candidate to beat Trump."

Three candidates - Sanders, Warren and Amy Klobuchar - have faced the unprecedented scenario of spending much of the past two weeks tethered to Washington for the impeachment trial of Trump instead of on the campaign trail in Iowa.

Even as candidates sought to make 11th-hour impressions on undecided voters, the senators were obligated to return to Washington for the trial's closing arguments on Monday.

Defeating Trump

In a vote scheduled for Wednesday, Trump is almost certain to be acquitted by the Republican-led upper house on charges of abuse of power and obstruction of Congress.

For Democrats, second-tier hopefuls Klobuchar and tech entrepreneur Andrew Yang look to outpace expectations and seize momentum heading into the next contest in New Hampshire on February 11.

Earlier on Monday Biden - who still holds the lead in national polls - brought pizza to a field office in a strip mall near Des Moines to thank volunteers.

"I'm feeling good about today," he said.

Like many candidates, Biden spent the weekend crisscrossing Iowa in a final push to convince undecided voters he is best placed to accomplish Democrats' number one goal: defeating Trump.

The president has not stood idly by. On Sunday he branded Biden "Sleepy Joe" and described Sanders as "a communist," previewing a likely line of attack were Sanders to win the nomination.

Unlike secret ballot voting, caucus-goers publicly declare their presidential choice by standing together with other supporters of a candidate.

Candidates who reach 15 percent support earn delegates for the nomination race while supporters of candidates who fall short can shift their allegiance to others.

Turnout is critical, and candidates and their representatives will seek to persuade voters on issues including healthcare, taxes and ending Washington corruption.

One key candidate who has opted not to contest in Iowa is billionaire businessman Michael Bloomberg, who entered the race in November but has surged into fourth place in RealClearPolitics' national polling average.

The former New York mayor, who has spent more than $300m on advertising, according to Advertising Analytics, is focused on running a national campaign with particular emphasis on states that vote on "Super Tuesday," on March 3.

May 19: A Chinese laboratory has been developing a drug it believes has the power to bring the coronavirus pandemic to a halt.

The outbreak first emerged in China late last year before spreading across the world, prompting an international race to find treatments and vaccines.

A drug being tested by scientists at China's prestigious Peking University could not only shorten the recovery time for those infected, but even offer short-term immunity from the virus, researchers say.

Sunney Xie, director of the university's Beijing Advanced Innovation Center for Genomics, told AFP that the drug has been successful at the animal testing stage.

"When we injected neutralising antibodies into infected mice, after five days the viral load was reduced by a factor of 2,500," said Xie.

"That means this potential drug has (a) therapeutic effect."

The drug uses neutralising antibodies -- produced by the human immune system to prevent the virus infecting cells -- which Xie's team isolated from the blood of 60 recovered patients.

A study on the team's research, published Sunday in the scientific journal Cell, suggests that using the antibodies provides a potential "cure" for the disease and shortens recovery time.

Xie said his team had been working "day and night" searching for the antibody.

"Our expertise is single-cell genomics rather than immunology or virology. When we realised that the single-cell genomic approach can effectively find the neutralising antibody we were thrilled."

He added that the drug should be ready for use later this year and in time for any potential winter outbreak of the virus, which has infected 4.8 million people around the world and killed more than 315,000.

"Planning for the clinical trial is underway," said Xie, adding it will be carried out in Australia and other countries since cases have dwindled in China, offering fewer human guinea pigs for testing.

"The hope is these neutralised antibodies can become a specialised drug that would stop the pandemic," he said.

China already has five potential coronavirus vaccines at the human trial stage, a health official said last week.

But the World Health Organization has warned that developing a vaccine could take 12 to 18 months.

Scientists have also pointed to the potential benefits of plasma -- a blood fluid -- from recovered individuals who have developed antibodies to the virus enabling the body's defences to attack it.

More than 700 patients have received plasma therapy in China, a process which authorities said showed "very good therapeutic effects".

"However, it (plasma) is limited in supply," Xie said, noting that the 14 neutralising antibodies used in their drug could be put into mass production quickly.

Using antibodies in drug treatments is not a new approach, and it has been successful in treating several other viruses such as HIV, Ebola and Middle East Respiratory Syndrome (MERS).

Xie said his researchers had "an early start" since the outbreak started in China before spreading to other countries.

Ebola drug Remdesivir was considered a hopeful early treatment for COVID-19 -- clinical trials in the US showed it shortened the recovery time in some patients by a third -- but the difference in mortality rate was not significant.

The new drug could even offer short-term protection against the virus.

The study showed that if the neutralising antibody was injected before the mice were infected with the virus, the mice stayed free of infection and no virus was detected.

This may offer temporary protection for medical workers for a few weeks, which Xie said they are hoping to "extend to a few months".

More than 100 vaccines for COVID-19 are in the works globally, but as the process of vaccine development is more demanding, Xie is hoping that the new drug could be a faster and more efficient way to stop the global march of the coronavirus.

"We would be able to stop the pandemic with an effective drug, even without a vaccine," he said.

Geneva, Jun 22: The global count of coronavirus cases has surpassed 8.7 million, with 183,020 new cases recorded on Sunday, the World Health Organisation said in its daily situation report.

Over the last 24 hours, 4,743 people died from COVID-19 worldwide, taking the death toll to 461,715 fatalities, according to the report.

The cumulative global toll of confirmed cases has now reached 8,708,008, as stated in the report.

The WHO Regional Director for Europe, Dr Hans Henri P. Kluge, shared that Europe accounts for 31 per cent of COVID-19 cases and 43 per cent of COVID-19 deaths globally.

Dr Kluge highlighted that several countries continue to face increasing disease incidence and that "preparing for the autumn is a priority now at the WHO Regional Office for Europe"

The United States continues to be worst affected by the contagion with the highest count of cases and fatalities -- 2.2 million and 118,895, respectively.

The novel coronavirus was declared a pandemic by WHO on March 11.
