Google Earth discovers 'lost pyramid complexes' in Egypt

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.

Washington, Apr 12: The US has overtaken Italy as the country with the highest number of deaths due to COVID-19 pandemic with the fatalities crossing 20,000, according to Johns Hopkins University data, as the novel coronavirus continues to wreak havoc across the globe.

The deadly coronavirus, that originated in China in December last year, has so far killed more than one lakh people across the globe. The United States on Saturday became the country with the highest number of deaths at 20,597, surpassing Italy's 19,468 fatalities.

More than 5.3 lakh Americans have tested positive for coronavirus, which is about the same for the next four countries put together: Spain (163,027), Italy (152,271), Germany (125,452) and France (93,790). In terms of fatalities, the US and Italy are followed by Spain (16,606), France (13832) and United Kingdom (9,875), the varsity data showed.

New York City, the financial capital of the world, has emerged as the epicenter of coronavirus in the world. A city of 8.3 million, which is one of the most densely populated cities in the US, by Saturday night had as many as 8,627 deaths and more than 180,000 people had tested positive for COVID-19.

President Donald Trump has declared a national emergency and all the 50 States have been notified with major disaster declaration. More than 95 per cent of the country's 330 million population are under stay-at-home order. Trump has deployed more than 50,000 personnel from the armed forces in fight against COVID-19.

After an initial two-week social mitigation measures, that includes social distancing, the measures have been extended till April 30. Initially, members of the White House Task Force on Coronavirus had projected between one and two lakhs deaths. Now, they have dropped the projection to 60,000 deaths, mainly due to the successful implementation of these measures.

"The people of our country have gone through a lot. But we did it the right way. And we look like we'll be coming in on the very, very low side, really below the lowest, the lowest side of the curve of death," Trump told Fox News on Saturday night.

Trump asserted that situation was improving in places like New York, where there is a drop in new patients. Responding to a question, he said he wanted the country to open up as soon as possible.

However, he has not taken a decision so far, even as some media reports said that he the President was looking for early May.

"I think it's going to be the toughest decision that I've ever made. I really, hopefully that I ever will have to make. But it's certainly the toughest decision that I've ever made. I hope that I'm going to make the right decision," Trump said, adding that he will be making a decision reasonably soon.

"We're setting up a council now of some of the most distinguished leaders in virtually every field including politics and business and medical. We'll be making that decision fairly soon," Trump said.

Meanwhile, The New York Times reported that its investigations have revealed that the president was warned about a potential pandemic but that internal divisions, lack of planning and his faith in his own instincts led to a halting response.

According to The Washington Post, coronavirus is killing about one in 10 hospitalised middle-aged patients and four in 10 older than 85 in the United States. It is particularly lethal to men even when taking into account common chronic diseases that exacerbate risk.

Globally, the novel coronavirus has killed 108,862 people and infected over 1.7 million people globally. The US has the highest number of infections at 529,887, according to Johns Hopkins University data.

Washington, May 19: As the scientists across the world are struggling to develop a vaccine for combating coronavirus, US drugmaker Moderna announced on Monday (local time) that the phase I trial of its Covid-19 vaccine has shown positive early results.

The company is hopeful that it's vaccine could be available to the public as early as January next year. Several firms across the world are in the race to develop a vaccine for the deadly virus which has claimed over 3 lakh lives worldwide.

CNN citing Dr. Tal Zaks, Moderna's chief medical officer reported that "if future studies go well, the company's vaccine could be available to the public as early as January".

"This is absolutely good news and news that we think many have been waiting for for quite some time," Zaks was quoted as saying.

Moderna, based in Cambridge, Massachusetts announced that the vaccine developed neutralising antibodies to the virus at levels reaching or exceeding the levels seen in people who have naturally recovered from Covid-19, reported CNN.

These will be followed by phase 2 trials and phase 3 trials, which Moderna plans to start in July.

President Donald Trump had on Friday said that that the United States will be able to deliver a few hundred million doses of COVID-19 vaccine, under 'Operation Warp Speed', by the end of this year.

"I have very recently seen early data from a clinical trial with a coronavirus vaccine and this data made me feel even more confident that we'll be able to deliver a few hundred million doses of vaccine by the end of 2020 and we will do the best we can," Trump had said at a press conference at the White House on Friday.
