An unmanned spacecraft blasted off Thursday on a yearlong journey to Mars, beginning one of China’s most ambitious space missions to date.The Tianwen-1 lifted off from the Wenchang Spacecraft Launch site on China’s southern Hainan Island aboard a Long March 5 rocket as hundreds of cheering fans gathered on beaches across the bay to witness the event.The Tianwen-1, which translates into “Heavenly Questions” or “Questions to Heaven,” is expected to reach the Red Planet by February.  Once it enters orbit, a landing probe will detach and land on the planet’s Utopia Planitia region, where it will release a small solar-powered rover that will explore the surface for at least three months.A successful landing would make China only the second nation to place a spacecraft on the Martian surface, with the…

One of the great mysteries of the coronavirus is how quickly it rocketed around the world.  It first flared in central China and, within three months, was on every continent but Antarctica, shutting down daily life for millions. Behind the rapid spread was something that initially caught scientists off guard, baffled health authorities and undermined early containment efforts — the virus could be spread by seemingly healthy people.As workers return to offices, children prepare to return to schools and those desperate for normalcy again visit malls and restaurants, the emerging science points to a menacing reality: If people who appear healthy can transmit the illness, it may be impossible to contain."It can be a killer and then 40 percent of people don't even know they have it," said Dr. Eric…

President Donald Trump has announced the U.S. government will provide an additional $5 billion in aid, equipment and training to the nation’s nursing homes, many of which are hot spots in the coronavirus pandemic.He said COVID-19, the disease caused by the coronavirus, poses "the greatest threat to our senior citizens," and that "nearly half of the deaths have occurred among those living in nursing homes or long-term care facilities."According to federal estimates, nursing home residents accounted for roughly 37,000 COVID-19-related deaths; overall, the U.S. has recorded nearly 143,000 deaths, according to Johns Hopkins University statistics.“I want to send a message of support and hope to every senior citizen who has been dealing with the struggle of isolation in what should be the golden years of your life," Trump said Wednesday…

The U.S. government will pay $1.95 billion to American drug maker Pfizer and German biotech company BioNTech SE for 100 million doses of a COVID-19 vaccine, if it proves to be safe and effective. The companies said Wednesday they finalized a deal with the U.S. Department of Health and Human Services and the Defense Department to supply the agencies with a vaccine they are developing jointly, the latest in a number of comparable agreements with other vaccine companies. FILE - Department of Health and Human Services Secretary Alex Azar speaks during a White House Coronavirus Task Force briefing in Washington, July 8, 2020.HHS Secretary Alex Azar told Fox News on Wednesday the U.S. could buy 500 million additional doses of the vaccine provided they are "safe and effective." The deal announced Wednesday is…

Laboratories across the U.S. are buckling under a surge of coronavirus tests, creating long processing delays that experts say are actually undercutting the pandemic response.With the U.S. tally of infections at 3.9 million Wednesday and new cases surging, the bottlenecks are creating problems for workers kept off the job while awaiting results, nursing homes struggling to keep the virus out and for the labs themselves, dealing with a crushing workload.Some labs are taking weeks to return COVID-19 results, exacerbating fears that asymptomatic people could be spreading the virus if they don’t isolate while they wait.“There’s been this obsession with, ‘How many tests are we doing per day?'” said Dr. Tom Frieden, former director of the Centers for Disease Control and Prevention. “The question is how many tests are being done…

The European Southern Observatory on Wednesday released the first image ever captured by a telescope of multiple planets orbiting around a sunlike star.In a statement, the ESO said the image was taken by its Extremely Large Telescope in Chile’s Atacama Desert.This image from the European Southern Observatory, July 2020, shows the star TYC 8998-760-1, upper left, and two exoplanets. The image was captured by blocking the light from the star, allowing for the fainter planets to be detected.The researchers who discovered the solar system said it was 300 light-years away, relatively close by galactic standards. They said the star was officially known as TYC 8998-760-1 and located in the Musca constellation (the Fly). They have determined it is barely 17 million years old, compared with our sun, which is believed…

COVID-19 tests that take an hour or less and can be done at doctors’ offices, workplaces, or even at home are under development. They could have a big impact on the course of the pandemic in the United States, where long lines for tests and long waits for results are undermining efforts to control the disease.  People who get tested for the coronavirus that causes COVID-19 have been waiting for days, up to a week in some places, to find out if they are infected, as overloaded labs struggle to keep up with demand. Patients can spread the virus while they are waiting for test results. That's also a setback for public health workers who need to identify patients' contacts and isolate them before the virus spreads further. Plus, patients tested one day…

A new study indicates that the accelerated melting of Arctic permafrost could release as much as 40 billion tons of carbon into the atmosphere not previously accounted for in global emissions estimates.  Permafrost is the thick layer of soil in the world's Arctic and Antarctic regions that, for centuries in some cases, has remained frozen throughout the year. It is vital to the world's climate because it stores twice as much carbon as there is in the atmosphere.   The study, published Monday in the science journal Nature Geoscience, examines how under usual circumstances, the top layer of this frozen soil thaws during summer when plants and microorganisms spring to life. The microbes eat plant roots and respirate like all living organisms and inevitably emit greenhouse gases, mostly carbon dioxide. This…

A study of the Arctic says polar bears are one of the most threatened species on earth because of melting sea ice caused by climate change, and without aggressive steps, the animals could be extinct by the end of the century. The University of Toronto study, published Monday in the journal Nature Climate Change, says that polar bears rely on sea ice to reach their prey, usually seals and other water mammals. Researchers who conducted the study say a loss of ice will force the animals onto land, where they must rely on fat reserves due to a lack of food. Co-author of a report on the study Steven Amstrup says the bears currently have less time to feed and a longer time to wait until the ice returns.  He says typically, the ice melts in the early summer and midsummer and returns in fall.  “That period when the ice is absent is getting ever longer and the bears are facing that longer period with less fat on board." Modelling was…

U.S. space agency astronauts Bob Behnken and Chris Cassidy Tuesday floated out of the International Space Station (ISS) on their fourth and final spacewalk to complete the upgrade of the station’s power supply system.Tuesday’s spacewalk is the fourth for the astronauts in under a month, and the 10th spacewalk in each of their careers, tying the U.S. record set by previous space station residents. It is the 12th total spacewalk since 2017 to upgrade the station’s batteries, and the 231st extravehicular mission in the history of the ISS.In under two weeks, Behnken and fellow commercial crew astronaut Doug Hurley, who monitored the spacewalk from inside the ISS, will depart the orbiting complex in the same SpaceX Dragon crew capsule in which they arrived at the end of May.SpaceX is aiming…

With over 14.7 million confirmed novel coronavirus cases and nearly 610,000 fatalities, researchers are reporting progress in the race to develop a safe and effective vaccine against the disease.  Two different experimental vaccines -- one developed in a joint venture between Britain’s Oxford University and British-Swedish drug maker AstraZeneca, the other by Chinese biotech firm CanSino Biologics -- have produced strong immune responses in late-stage human trials, according to two peer-reviewed studies published Monday in the British medical journal The Lancet.   Meanwhile, U.S. drug maker Pfizer and its German partner BioNTech also reported positive progress Monday on their vaccine candidate.  The vaccine developed by the joint Oxford-AstraZeneca partnership is receiving the most attention, with the company having signed agreements with many governments to supply its vaccine if it is proved to be effective and granted regulatory approval. The company has…

Officials in the Bahamas say that starting Wednesday, it will ban travelers from the United States due to the coronavirus pandemic. Officials say the large increase in COVID-19 cases throughout the United States and other countries is the reason for the ban; however, some international travel will be permitted, although it will be confined to Canada, Britain, and the European Union. COVID-19 is the disease caused by the coronavirus. The ban marks a sudden shift from the Bahamas’ decision three weeks ago to reopen to virtually all international tourism. Those still permitted to travel to the Bahamas under the new requirements must test negative for COVID-19 from an accredited lab 10 or fewer days before traveling, or otherwise quarantine themselves for 14 days. “Regrettably, the situation here at home has already deteriorated since we…

Scientists at Oxford University say their experimental coronavirus vaccine has been shown in an early trial to prompt a protective immune response in hundreds of people who got the shot.British researchers first began testing the vaccine in April in about 1,000 people, half of whom got the experimental vaccine. Such early trials are usually designed only to evaluate safety, but in this case experts were also looking to see what kind of immune response was provoked.In research published Monday in the journal Lancet, scientists said that they found their experimental COVID-19 vaccine produced a dual immune response in people aged 18 to 55."We are seeing good immune response in almost everybody," said Dr. Adrian Hill, director of the Jenner Institute at Oxford University. "What this vaccine does particularly well is…

Cameroon's medical authorities say over 200,000 children have not received routine vaccinations on schedule since March, when the country had its first case of COVID-19.  Parents are refusing to take their kids to hospitals because they fear they may be infected with the virus, which has spread to nearly 17,000 people and caused nearly 400 deaths.  Doctors are warning that without the vaccinations, children in Cameroon risk preventable diseases such as diphtheria, the measles, and tetanus.  A 4-month-old baby cries as she receives her second polio vaccine at the Chantal Biya Foundation Hospital in Cameroon’s capital Yaounde. Elizabeth Mbungong, 27, says she is getting her baby’s booster shot nearly three months late because she was scared of going to the hospital during the COVID-19 pandemic. "I gave birth in the month of March and the first vaccine was given…

Astrophysicists on Monday published the largest-ever 3D map of the Universe, the result of an analysis of more than 4 million galaxies and ultra-bright, energy-packed quasars.The efforts of hundreds of scientists from about 30 institutions worldwide have yielded a "complete story of the expansion of the universe," said Will Percival of the University of Waterloo in Ontario, Canada.In the project launched more than two decades ago, the researchers made "the most accurate expansion history measurements over the widest-ever range of cosmic time," he said in a statement.The map relies on the latest observations of the Sloan Digital Sky Survey (SDSS), titled the "extended Baryon Oscillation Spectroscopic Survey" (eBOSS), with data collected from an optical telescope in New Mexico over six years.The infant universe following the big bang is relatively well…

The United Arab Emirates launched its first mission to Mars early Monday as it strives to develop its scientific and technology capabilities and move away from its reliance on oil. The Hope Probe blasted off from Japan's Tanegashima Space Center at 1:58 a.m. UAE time/6:58 a.m. Japanese time Monday (2158 GMT Sunday) for a seven-month journey to the Red Planet, where it will orbit and send back data about the atmosphere. The first Arab mission to Mars was initially set to launch July 14 but had been delayed twice because of bad weather. There are currently eight active missions exploring Mars; some orbit the planet and some have landed on its surface. China and the United States each plan to send another this year. The Emirates Mars Mission has cost…

The World Health Organization reports the COVID-19 pandemic and lack of money are hampering efforts to bring a speedy end to the Ebola outbreak in Democratic Republic of Congo’s Equateur Province.  Since the outbreak was declared June 1, 56 cases, including 20 deaths have been recorded.Shortly after Ebola was detected in the DRC, World Health Officials expressed confidence they would be able to quickly control the spread of the deadly virus.  They noted many lessons had been learned from previous outbreaks.  They said the availability of a vaccine, and therapeutics could help them prevent the onset of the disease and treat those who fell ill.   World Health Organization spokeswoman, Fadela Chaib says these new tools are being used to good effect.  Over the course of four days, she says 12,000…

Actor and activist Angelina Jolie urged the U.N. Security Council on Friday to fulfill its promise to hold to account perpetrators of sexual violence against children in conflict settings.“I have met child survivors of sexual violence – and domestic violence and trauma and abuse – everywhere,” Jolie said of her 20 years working with the U.N. refugee agency. “There is no continent untouched by these crimes.”She addressed a council session reflecting on the issue, one year after adoption of Resolution 2467, which strengthened prevention through justice and accountability mechanisms, empowered the council to impose sanctions on perpetrators, and opened the way for victims to seek reparations.Jolie gave the example of Yazidi children she had met in northern Iraq. Thousands of their mothers and female relatives have been abducted, enslaved and…

Researchers have discovered one of the blackest materials on Earth – material that reflects less than .5 percent of the light that hits it – on the skin of deep-sea fish that use their blackness as camouflage from predators.The fish's skin and its possible applications in the above-water world are described in a study published Thursday in the science journal Current Biology. The lead author of the study, Smithsonian Natural History Museum zoologist Karen Osborn, said in her research she kept coming across black fish that she could not quite photograph — she could only capture their silhouette.This inspired her to capture samples of the fish and examine them. Deep-sea fish of this nature, she said, use their blackness to escape predators. In their environment, where sunlight cannot reach, many…

The European Space Agency (ESA) and NASA have released the Images of the sun taken with the Polarimetric and Helioseismic Imager and Extreme Ultraviolet Imager of the Solar Orbiter spacecraft are seen in a combination of photos released by NASA, July 16, 2020.The campfires could help explain why the corona, the Sun’s upper atmosphere, is 300 times hotter than the solar surface.Of the Solar Orbiter’s 10 instruments, six are imaging devices, each studying a different aspect of the sun.The Solar and Heliospheric Imager (SoloHI) exposed zodiacal light — light from the sun reflecting off interplanetary dust. To capture it, the imager had to dim the sun’s light to one-trillionth of its normal brightness.The Polar and Helioseismic Imager (PHI) mapped the sun’s magnetic field. Four instruments meant for measuring the space…
