The commercial space launch company Blue Origin, in partnership with the U.S. space agency NASA, launched an unmanned reusable suborbital rocket into space Tuesday and landed it on a West Texas launch site. The 12-minute flight, 100 kilometers to the edge of space and back, was a test of a number of new technologies, including two NASA precision descent and landing sensor systems, which could be used in future landers on the moon and Mars, and are able to intelligently identify and avoid potential hazards on target landing zones. FILE – A general view of the Blue Origin New Shepard rocket booster at the 33rd Space Symposium in Colorado Springs, Colorado, Apr. 5, 2017.The launch included Blue Origin’s six-person crew capsule, which is designed with future commercial passengers in mind, including what the company says are the largest windows ever designed for a spacecraft. Once in space, the capsule separated from the launch rocket. The reusable rocket, named New Shepard after the first U.S. astronaut in space, Alan Shepard, touched down at the Texas launch and landing site with a controlled, engine-powered descent. The capsule landed a short time later using three large parachutes.  The capsule contained a variety of experiments and other payloads, including postcards provided by children from across the country. Blue Origin is owned by U.S. investor and entrepreneur Jeff Bezos, the CEO of Amazon.com.

Britain’s opposition Labor Party Leader Keir Starmer on Tuesday called on the government to implement a three-week temporary nationwide “circuit breaker” lockdown to stop the spread of COVID-19 throughout Britain.Starmer made the proposal in a speech in London, one day after Prime Minister Boris Johnson introduced his three-tiered regional alert plan designed to simplify and standardize the variety of COVID-related restrictions that have been imposed around the country.But Starmer said Britain is in a decisive moment in the fight against the virus and “there’s no longer time to give this prime minister the benefit of the doubt.””This was not inevitable, but it is now necessary,” he said, acknowledging that the restrictions are largely unpopular.Britain’s Prime Minister Boris Johnson speaks during a coronavirus briefing in Downing Street, London, Oct. 12, 2020.He also said the lockdown idea comes from recommendations made by Britain’s Scientific Advisory Group for Emergencies (SAGE) which said “a package of stringent interventions is now urgently needed” to lower the rate of infection and take strain off hospitals and the National Health service.Quoting SAGE, the opposition leader said, “not acting now will result in a very large epidemic with catastrophic consequences.”Starmer proposed allowing only essential work and travel, restricting household mixing and that all pubs, bars and restaurants should be closed, but also be compensated. He said he understood the measures would require “significant sacrifices across the country.”The Labor Party leader added that schools would not have to close under his proposal, as the lockdown would be timed to coincide with an upcoming school holiday.Speaking directly to Prime Minister Johnson, Starmer said: “You know that the scientific evidence backs this approach … that the restrictions that you introduced won’t be enough.”Starmer’s words will only increase the pressure on the British leader, who has defended his decision not to re-introduce a full lockdown by saying he was trying to protect lives and livelihoods by balancing public health and the economy.

The United Nations is warning that climate change is threatening the lives of millions of people throughout the world, and that demand for humanitarian aid could rise 50% by 2030. The U.N.’s World Meteorological Organization released a report Tuesday that found more weather-related disasters such as heat waves, storms and droughts are occurring each year. “While COVID-19 generated a large international health and economic crisis from which it will take years to recover, it is crucial to remember that climate change will continue to pose an ongoing and increasing threat to human lives, ecosystems, economies and societies for centuries to come,” said WMO Secretary-General Petteri Taalas.  The 2020 State of Climate Services Report said 11,000 disasters attributed to weather have taken place over the past 50 years, causing 2 million deaths and $3.6 trillion in economic damage.  The report also said 108 million people worldwide needed humanitarian help in 2018 because of natural disasters. Despite the increase in weather-related disasters over that period, the report noted that the average number of fatalities from each disaster per year fell by one-third. In addition to the U.N., the report was prepared by 15 other international agencies and financial institutions. They urge governments to invest more in early-warning systems that can help countries more effectively respond and mitigate the impact of natural disasters.

U.S. pharmaceutical giant Johnson & Johnson paused its late-stage clinical trials of its COVID-19 vaccine after a participant was diagnosed with an unexplained illness. The pause was first reported Monday by the health care news website Stat, which obtained a document the company sent to outside researchers.  Johnson & Johnson had just launched its wide scale testing of its single-dose experimental vaccine. The trial involves 60,000 volunteers across more than 200 locations in the United States and internationally, including Argentina, Brazil, Chile, Mexico and South Africa.   The company said in a statement that so-called “adverse events” such as illnesses and accidents are an expected part of a clinical study, especially with such a large number of participants.  It also said the hold was a “study pause” and not a “clinical hold” which is imposed by a formal health regulatory agency.  Because it can be administered in a single dose, Johnson & Johnson’s vaccine has significant advantages over the other three potential vaccines, which require two doses.   The single-dose vaccine would not have to be kept frozen in ultracold temperatures, making it easier to utilize in a mass immunization campaign.   The Johnson & Johnson vaccine trial is the second to be put on hold after a volunteer became ill after receiving the vaccine.  U.S.-based drugmaker AstraZeneca halted its late-stage trial of a vaccine developed with the University of Oxford early last month after a volunteer in Britain was diagnosed with transverse myelitis, an inflammatory syndrome that affects the spinal cord and is often sparked by viral infections.  FILE – A worker feeds vials for production of SARS CoV-2 Vaccine for COVID-19 at the SinoVac vaccine factory in Beijing.The late-stage testing of that vaccine has resumed in Britain, Brazil, India and South Africa, but remains on hold in the United States.  Meanwhile, a new study suggests that a person infected with COVID-19 is still vulnerable to the disease. A report published Monday in The Lancet Infectious Diseases medical journal revealed a 25-year-old man in (the western U.S. state of) Nevada first tested positive with COVID-19 back in April, then a second time in June with more severe symptoms that led to him being placed on oxygen.    Researchers say the man was infected with two distinct strains of the novel coronavirus, but could not be sure why the second infection was worse. He may have been exposed to a higher dose of the virus the second time, or the later version was more virulent than the first. This is the first confirmed case of COVID-19 reinfection in the United States, and just the fifth of its kind in the world, with one patient each in Belgium, the Netherlands, Hong Kong and Ecuador. The researchers say the reinfections suggest that previous exposure to the coronavirus “does not necessarily translate to guaranteed total immunity.” The Lancet study appears to support a warning by the World Health Organization against a strategy of pursuing herd immunity to stop the coronavirus pandemic, calling the idea unethical.    At a news briefing in Geneva Monday, WHO Director-General Tedros Adhanom Ghebreyesus said health officials should only try to achieve immunity through vaccination, not through exposing people to the virus.     Herd immunity happens when a population is protected from a virus because a threshold immunity has been reached in that society.     “Never in the history of public health has herd immunity been used as a strategy for responding to an outbreak, let alone a pandemic. It’s scientifically and ethically problematic,” Dr. Tedros said.     The WHO estimates that about 10% of the world has contracted the coronavirus. It is not yet known what percentage rate of infection is needed to achieve herd immunity.   Tedros noted that to obtain herd immunity from measles, about 95% of the population must be vaccinated, while for polio, the threshold is about 80%.

A late-stage study of Johnson & Johnson’s COVID-19 vaccine candidate has been paused while the company investigates whether a study participant’s “unexplained illness” is related to the shot. The company said in a statement Monday evening that illnesses, accidents and other so-called adverse events “are an expected part of any clinical study, especially large studies,” but that its physicians and a safety monitoring panel would try to determine what might have caused the illness. The pause is at least the second such hold to occur among several vaccines that have reached large-scale final tests in the U.S. The company declined to reveal any more details about the illness, citing the participant’s privacy. Temporary stoppages of large medical studies are relatively common. Few are made public in typical drug trials, but the work to make a coronavirus vaccine has raised the stakes on these kinds of complications. Companies are required to investigate any serious or unexpected reaction that occurs during drug testing. Given that such tests are done on tens of thousands of people, some medical problems are a coincidence. In fact, one of the first steps the company said it will take is to determine if the person received the vaccine or a placebo.FILE – A worker feeds vials for production of SARS CoV-2 Vaccine for COVID-19 at the SinoVac vaccine factory in Beijing.The halt was first reported by the health news site STAT. Final-stage testing of a vaccine made by AstraZeneca and Oxford University remains on hold in the U.S. as officials examine whether an illness in its trial poses a safety risk. That trial was stopped when a woman developed severe neurological symptoms consistent with transverse myelitis, a rare inflammation of the spinal cord, the company has said. That company’s testing has restarted elsewhere. Johnson & Johnson was aiming to enroll 60,000 volunteers to prove if its single-dose approach is safe and protects against the coronavirus. Other vaccine candidates in the U.S. require two shots.

Microsoft announced legal action Monday seeking to disrupt a major cybercrime digital network that uses more than 1 million zombie computers to loot bank accounts and spread ransomware, which experts consider a major threat to the U.S. presidential election. The operation to knock offline command-and-control servers for a global botnet that uses an infrastructure known as Trickbot to infect computers with malware was initiated with an order that Microsoft obtained in Virginia federal court on Oct. 6.  Microsoft argued that the crime network is abusing its trademark. “It is very hard to tell how effective it will be, but we are confident it will have a very long-lasting effect,” said Jean-Ian Boutin, head of threat research at ESET, one of several cybersecurity firms that partnered with Microsoft to map the command-and-control servers. “We’re sure that they are going to notice and it will be hard for them to get back to the state that the botnet was in.” Cybersecurity experts said that Microsoft’s use of a U.S. court order to persuade internet providers to take down the botnet servers is laudable. But they add that it’s not apt to be successful because too many won’t comply and because Trickbot’s operators have a decentralized fall-back system and employ encrypted routing. Paul Vixie of Farsight Security said via email “experience tells me it won’t scale — there are too many IP’s behind uncooperative national borders.” And the cybersecurity firm Intel 471 reported no significant hit on Trickbot operations Monday and predicted “little medium- to long-term impact” in a report shared with The Associated Press.  But ransomware expert Brett Callow of the cybersecurity firm Emsisoft said that a temporary Trickbot disruption could, at least during the election, limit attacks and prevent the activation of ransomware on systems already infected.  The announcement follows a Washington Post report Friday of a major — but ultimately unsuccessful — effort by the U.S. military’s Cyber Command to dismantle Trickbot beginning last month with direct attacks rather than asking providers to deny hosting to domains used by command-and-control servers.  A U.S. policy called “persistent engagement” authorizes U.S. cyberwarriors to engage hostile hackers in cyberspace and disrupt their operations with code, something Cybercom did against Russian misinformation jockeys during U.S. midterm elections in 2018. Created in 2016 and used by a loose consortium of Russian-speaking cybercriminals, Trickbot is a digital superstructure for sowing malware in the computers of unwitting individuals and websites. In recent months, its operators have been increasingly renting it out to other criminals who have used it to sow ransomware, which encrypts data on target networks, crippling them until the victims pay up. One of the biggest reported victims of a ransomware variety sowed by Trickbot called Ryuk was the hospital chain Universal Health Services, which said all 250 of its U.S. facilities were hobbled in an attack last month that forced doctors and nurses to resort to paper and pencil.  U.S. Department of Homeland Security officials list ransomware as a major threat to the Nov. 3 presidential election. They fear an attack could freeze up state or local voter registration systems, disrupting voting, or knock out result-reporting websites.  While cybersecurity experts say the operators of Trickbot and affiliated digital crime syndicates are Russian speakers mostly based in eastern Europe, they caution that they are motivated by profit, not politics. They do, however, operate with impunity with no Kremlin interference as long as their targets are abroad.  “In today’s world, Trickbot is a type of a plague,” said Alex Holden, founder of Milwaukee-based Hold Security, which tracks its activity closely on the dark web, “and a government that ignores a global plague is more than complacent.” Trickbot is “malware-as-a-service,” its modular architecture lets it be used as a delivery mechanism for a wide array of criminal activity. It began mostly as a so-called banking Trojan that attempts to steal credentials from online bank account so criminals can fraudulently transfer cash. But recently, researchers have noted a rise in Trickbot’s use in ransomware attacks targeting everything from municipal and state governments to school districts and hospitals. Ryuk and another type of ransomware called Conti — also distributed via Trickbot — dominated attacks on the U.S. public sector in September, said Callow of Emsisoft.  Holden said the reported Cybercom disruption — involving efforts to confuse its configuration through code injections — succeeded in temporarily breaking down communications between command-and-control servers and most of the bots. “But that’s hardly a decisive victory,” he said, adding that the botnet rebounded with new victims and ransomware. The disruption — in two waves that began Sept. 22 — was first reported by cybersecurity journalist Brian Krebs. The AP could not immediately confirm the reported Cybercom involvement.

U.S. President Donald Trump’s doctor says the president has tested negative for COVID-19 on “consecutive days” as Trump traveled to Florida for his first campaign rally since being diagnosed with the disease earlier this month.In a memo released Monday by the White House, Dr. Sean Conley said Trump was tested using a newer rapid coronavirus test from Abbott Laboratories. He did not say when Trump was tested.Conley said the negative tests, along with other clinical and laboratory data, “indicate a lack of detectable viral replication.” He also repeated an assessment that he gave over the weekend that Trump is no longer infectious to others.Trump returned to the campaign trail Monday for a busy week that includes stops in Florida, Pennsylvania, Iowa, North Carolina and Wisconsin, his first campaign travel since his positive test for COVID-19, the disease caused by the coronavirus, on Oct 2. Trump spent several days at Walter Reed National Military Medical Center and completed his COVID-19 treatment at the White House.Dr. Anthony Fauci, director of the National Institute for Allergy and Infectious Diseases, speaks during a House Subcommittee on the Coronavirus crisis hearing, July 31, 2020 on Capitol Hill in Washington.Dr. Anthony Fauci, speaking on CNN before Trump left the White House for Florida, questioned the wisdom of holding an event like this. Test positivity rates, he noted, are climbing in parts of the Sun Belt.“We know that that is asking for trouble when you do that,” Fauci, the nation’s top infectious-disease expert, said on CNN.Trump described himself Sunday as being “in very good shape” and said he was no longer taking any medication.FILE – President Donald Trump walks out of Walter Reed National Military Medical Center after receiving treatment as a COVID-19 patient, in Bethesda, Maryland, Oct. 5, 2020.“I beat this crazy, horrible China virus,” Trump said in a telephone interview on Fox News Channel’s “Sunday Morning Futures” show. “It seems like I’m immune, maybe a long time, a short time, maybe a lifetime.”Those who recover from COVID-19 are likely to be immune for some period of time, Fauci told CNN on Monday, but there are cases emerging in which patients are reinfected weeks or months later, he added.Trump said he had a “protective glow” after being treated with several medications during his hospital stay and after returning to the White House last week.A short time after the television interview, Trump said of the coronavirus on Twitter, “I can’t get it (immune), and can’t give it. Very nice to know!!!”Twitter disabled some sharing options on the tweet and labeled it for violating “Twitter Rules about spreading misleading and potentially harmful information related to COVID-19.”Facebook did nothing to the same post by Trump on its platform.The U.S. Centers for Disease Control and Prevention has provided limited information about immunity and reinfection. A person who has recovered from COVID-19 may have low levels of the virus in their bodies for up to three months after diagnosis and not be infectious to others.“This science does not imply a person is immune to reinfection with SARS-CoV-2, the virus that causes COVID-19, in the three months following infection,” the CDC said. The coronavirus has killed nearly 215,000 people in the United States and infected more than 7.8 million Americans, according to Johns Hopkins University data. The U.S. leads the world in the number of confirmed cases and deaths, according to Johns Hopkins.Some medical experts have also voiced skepticism that Trump could be declared contagion-free so soon, according to the Associated Press.It also was unclear what — if any — added precautions and safety measures the campaign planned to take to prevent the trips from further spreading a virus that has already infected many of the president’s closest aides and allies, including his campaign manager and the head of the Republican Party, according to the AP.CDC guidelines for limiting exposure to the coronavirus is washing your hands, wearing a face mask that covers your mouth and nose when around others, and socially distancing by keeping at least 2 meters between you and others.
