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.

New Delhi, Feb 10: Former Jammu and Kashmir chief minister Omar Abdullah's sister on Monday moved the Supreme Court to challenge his detention under the Public Safety Act.

Senior advocate Kapil Sibal, appearing for the petitioner, mentioned the matter for urgent listing before a bench headed by Justice N V Ramana.

Sibal told the bench that they have filed a habeas corpus petition challenging the detention of Abdullah under the PSA and the matter should be heard this week.

The bench agreed for urgent listing of the matter.

Beijing, Feb 19: The death count from China's new coronavirus epidemic jumped to 2,000 on Wednesday after 132 more people died in Hubei province, the hard-hit epicentre of the outbreak.

In its daily update, the province's health commission also reported 1,693 new cases of people infected with the virus.

This brings the total number of cases in mainland China past 74,000.

Most of the cases are in Hubei, where the virus first emerged in December before spiralling into a nationwide epidemic.

Wednesday's jump in the death count was an increase on Tuesday's figures, although the number of new cases reported in Hubei were the lowest for a week.

A study released by Chinese officials claimed most patients have mild cases of the illness.

Outside of hardest-hit Hubei, which has been effectively locked down to try to contain the virus, the number of new cases has been slowing and China's national health authority has said this is a sign the outbreak is under control.

President Xi Jinping, in a phone call with the British prime minister, said China's measures were achieving "visible progress", according to state media Tuesday.

However, the World Health Organization has cautioned that it was too early to tell if the decline would continue.

On Tuesday the director of a hospital in the central Hubei city of Wuhan became the seventh medical worker to succumb to the COVID-19 illness.

Washington, Apr 28: After nearly three weeks in an intensive care unit in Los Angeles, doctors treating 41-year-old Broadway actor Nick Cordero for COVID-19 were forced to amputate his right leg.

The flow of blood had been impeded by a blood clot: yet another dangerous complication of the disease that has been bubbling up in frontline reports from China, Europe and the United States.

To be sure, so-called "thrombotic events" occur for a variety of reasons among intensive care patients, but the rates among COVID-19 patients are far higher than would be otherwise expected.

"I have had 40-year-olds in my ICU who have clots in their fingers that look like they'll lose the finger, but there's no other reason to lose the finger than the virus," Shari Brosnahan, a critical care doctor at NYU Langone said.

One of these patients is suffering from a lack of blood flow to both feet and both hands, and she predicts an amputation may be necessary, or the blood vessels may get so damaged that an extremity could drop off by itself.

Blood clots aren't just dangerous for our limbs, but can make their way to the lungs, heart or brain, where they may cause lethal pulmonary embolisms, heart attacks, and strokes.

A recent paper from the Netherlands in the journal Thrombosis Research found that 31 percent of 184 patients suffered thrombotic complications, a figure that the researchers called "remarkably high" -- even if extreme consequences like amputation are rare.

Behnood Bikdeli, a doctor at New York-Presbyterian Hospital, assembled an international consortium of experts to study the issue. Their findings were published in the Journal of The American College of Cardiology.

The experts found the risks were so great that COVID-19 patients "may need to receive blood thinners, preventively, prophylactically," even before imaging tests are ordered, said Bikdeli.

What exactly is causing it? The reasons aren't fully understood, but he offered several possible explanations.

People with severe forms of COVID-19 often have underlying medical conditions like heart or lung disease -- which are themselves linked to higher rates of clotting.

Next, being in intensive care makes a person likelier to develop a clot because they are staying still for so long. That's why for example people are encouraged to stretch and move around on long haul flights.

It's also now clear the COVID-19 illness is associated with an abnormal immune reaction called "cytokine storm" -- and some research has indicated this too is linked to higher rates of clotting.

There could also be something about the virus itself that is causing coagulation, which has some precedent in other viral illnesses.

A paper in the journal The Lancet last week showed that the virus can infect the inner cell layer of organs and of blood vessels, called the endothelium. This, in theory, could interfere with the clotting process.

According to Brosnahan, while thinners like Heparin are effective in some patients, they don't work for all patients because the clots are at times too small.

"There are too many microclots," she said. "We're not sure exactly where they are."

Autopsies have in fact shown some people's lungs filled with hundreds of microclots.

The arrival of a new mystery however helps solve a slightly older one.

Cecilia Mirant-Borde, an intensive care doctor at a military veterans hospital in Manhattan, told AFP that lungs filled with microclots helped explain why ventilators work poorly for patients with low blood oxygen.

Earlier in the pandemic doctors were treating these patients according to protocols developed for acute respiratory distress syndrome, sometimes known as "wet lung."

But in some cases, "it's not because the lungs are occupied with water" -- rather, it's that the microclotting is blocking circulation and blood is leaving the lungs with less oxygen than it should.

It has just been a little under five months since the virus emerged in Wuhan, China, and researchers are learning more about its impact every day.

"While we react surprised, we shouldn't be as surprised as we were. Viruses tend to do weird things," said Brosnahan.

While the dizzying array of complications may seem daunting, "it's possible there'll be one or a couple of unifying mechanisms that describe how this damage happens," she said.

"It's possible it's all the same thing, and that there'll be the same solution."
