Physicians and engineers in the Netherlands said they are developing a “smart mask” that uses sensors and data to monitor a wearer's temperature and respiration and warns them when the mask needs replacing.Though the mask is still in the development stage, researchers at the Holst Center, an independent research and development technology lab in the city of Eindhoven, said in addition to monitoring vital signs, a humidity sensor can indicate if the mask is functioning properly.   The core technology has already been largely developed in a joint research project with multiple partners to commercialize the smart mask. Holst Center researcher Ashok Sridhar said the mask was designed with practical applications to indicate if the wearer is basically healthy.Sridhar said the mask will also tell wearers how the mask itself is…

Ángela López hardly fits the profile of a rule-breaker. But the mother of a 7-year-old girl with respiratory problems has found herself among parents ready to challenge Spanish authorities on a blanket order to return to school.     They are wary of safety measures they see as ill-funded as a new wave of coronavirus infections sweeps the country. They fear sick students could infect relatives who are at higher risk of falling ill from COVID-19. And they claim that they have invested in computers and better network connections to prepare for online lessons, even preparing to homeschool their children if necessary.   Many of the defiant parents, including López, are also ready to stand up to the country’s rigid, one-size-fits-all rule of mandatory in-school education, even if that means…

The Lost Summer of 2020 drew to a close Monday with many big Labor Day gatherings canceled across the U.S. and health authorities pleading with people to keep their distance from others so as not to cause another coronavirus surge like the one that followed Memorial Day. Downtown Atlanta was quiet as the 85,000 or so people who come dressed as their favorite superheroes or sci-fi characters for the annual Dragon Con convention met online instead. Huge football stadiums at places like Ohio State and the University of Texas sat empty. Many Labor Day parades marking the unofficial end of summer were called off, and masks were usually required at the few that went on. "Please, please do not make the same mistakes we all made on Memorial Day weekend.…

Spain has become the first nation in Western Europe to exceed a half-million COVID-19 total infections, as the total number of cases around the world surged to 27.3 million, including 893,000 deaths.Data from Spain’s Health Ministry showed a total of 525,549 cases as of Tuesday, including 29,516 deaths.  In comparison, France has recorded 367,174 total infections and 30,732 deaths, while Britain has 352,451 total cases, including 41,643 deaths, according to Johns Hopkins University’s coronavirus tracking project.    Social culture Spain imposed one of the world’s strictest lockdowns at the pandemic’s peak back in March, when the country’s hospitals were overwhelmed with new coronavirus patients and the number of fatalities exceeded more than 800 on a daily basis. The outbreak eventually was brought under control, but the number of new infections has steadily risen since the country began…

In April, during the height of the coronavirus lockdown, Trump administration health experts hailed a test that would confirm if someone had already had the virus and therefore couldn't get sick again. The antibody test would show who might have "the wonderful, beautiful immunity," President Donald Trump said was needed to get the nation working again. Months later, the tests exist but haven't fulfilled their promise of allowing Americans to reclaim their lives, said Dr. Jennifer Rakeman of New York City's Public Health Laboratory. In fighting off the virus, the body makes antibodies, which the tests measure. Unfortunately, scientists are still figuring out how well and for how long antibodies provide the immunity that protects against another infection by the coronavirus.  An Indian girl cries as a medical worker collects her swab sample…

Researchers in Australia say they have developed a technique to make coal-fired power plants run without coal. They say new thermal energy storage blocks can heat water, which, in turn, produces steam to power turbines using existing power station infrastructure. Researchers at the University of Newcastle in New South Wales say their thermal blocks would allow coal-fired power stations to run coal-free, delivering clean, renewable electricity.   The bricks are made of graphite and metals, including zinc and aluminum, plus other undisclosed materials.   The Australian team says they store energy from solar and wind farms in the form of heat, which can make steam to run electricity-generating turbines.   The aim is to fit the technology to existing power stations where, instead of burning coal, the blocks would generate power without pollution.     Professor of engineering at Australia’s University of Newcastle Erich Kisi says the technology would allow coal-fired stations to phase out the use of the fossil fuel. “As coal burning is reduced, storage…

Bright green stalks of weeds are sprouting from the ground where planes were supposed to take off at a new Mexico City airport as officials let nature take over in their bid to transform the marshy swath of an ancient lake into a giant park. The ghostly skeletons of a partly built control tower and flight terminal are recognizably in the style of Norman Foster, the British architect commissioned by Mexico's last president to build a futuristic international airport at a cost of $13 billion on 4,800 hectares just east of the capital. Upon taking office in December 2018, President Andres Manuel Lopez Obrador axed the project, citing the results of an informal referendum, after arguing it would be costly to prevent sinking on the waterlogged soil. Instead of the slick design from…

Bulked-up, mutant "mighty mice" held onto their muscle during a monthlong stay at the International Space Station, returning to Earth with ripped bodybuilder physiques, scientists reported Monday.  The findings hold promise for preventing muscle and bone loss in astronauts on prolonged space trips like Mars missions, as well as people on Earth who are confined to bed or need wheelchairs. A research team led by Dr. Se-Jin Lee of the Jackson Laboratory in Connecticut sent 40 young female black mice to the space station in December, launching aboard a SpaceX rocket.  In a paper published in the Proceedings of the National Academy of Sciences, Lee said the 24 regular untreated mice lost considerable muscle and bone mass in weightlessness as expected — up to 18%. But the eight genetically engineered "mighty mice"…

Wildfires have burned more than 2 million acres in California this year, setting a state record even as crews battled dozens of growing blazes in sweltering temperatures Monday that strained the electrical grid and threatened power outages for millions. The most striking thing about the record is how early it was set, with the most dangerous part of the year ahead, said Lynne Tolmachoff, spokeswoman for the California Department of Forestry and Fire Protection, or Cal Fire. "It's a little unnerving because September and October are historically our worst months for fires," she said. "It's usually hot, and the fuels really dry out. And we see more of our wind events." The previous high was 1.96 million acres (793,184 hectares) burned in 2018. Cal Fire began tracking the numbers in 1987. Firefighters struggled to…

Suellen de Souza could no longer endure the confinement. After six months of precautions, the Brazilian nursing technician decided that Sunday would be her first day at the beach since the pandemic began. "This week it was very hot ... the truth is I really wanted to come" to the beach, said the 21-year-old at Rio de Janeiro's Ipanema beach, which is technically still closed to sun-bathers though few respect the prohibition and authorities seldom enforce it. Under a burning midday sun, she had difficulty finding an empty space in the sand as thousands crowded the famed beach, which was dotted with hundreds of umbrellas and families sunning themselves. Beach-goers were packed close together with few wearing face masks. With tentative signs the coronavirus pandemic is easing, Brazilians exhausted with…

The World Health Organization says it is unlikely a safe, effective vaccine against COVID-19 will be available for widespread use before the middle of next year.  Urging people to lower their expectations, health officials say the development of a safe, efficacious vaccine takes time and cannot be rushed.  As it is, the WHO reports remarkable progress is being made toward this end. It notes at least six to nine candidate vaccines have begun Phase 3 clinical trials.   WHO spokeswoman Margaret Harris says many thousands of people participate in these carefully crafted trials. She says a vaccine must be proven to be safe and seen to provide protection against the coronavirus in at least 50% of subjects before it can be approved for public use.      Harris says the…

Wildfires in the Arctic have already released more planet-warming carbon dioxide this year than all of last year, with smoke plumes from the fires covering an area more than one-third the size of Canada, according to new data from the FILE - In this July 10, 2020 file image taken from video provided by Russian Emergency Ministry, a Russian aircraft releases water in the Trans-Baikal National Park in Buryatia, southern Siberia.Previous studies show that climate change is warming Arctic regions around two times the rate of other parts of the planet.  According to Hoy, as cold and wet regions become dry and flammable, fires burn more readily. The fires can be started by human activity, lightning strikes, or “zombie fires” — fires that smolder beneath the ground over winter.Satellite measurements…

New studies by the World Health Organization and the United Nations show people suffering from noncommunicable diseases are more susceptible to becoming severely ill and dying from COVID-19.Noncommunicable diseases kill more than 40 million people a year worldwide. The World Health Organization says seven out of 10 deaths globally are caused by cardiovascular diseases, cancer, diabetes, respiratory and other NCDs.Of those, the data show, 17 million people die prematurely, the great majority between the ages of 30 and 70.  Most of the deaths occur in low-income countries.Nick Banatvala, the head of a U.N. task force on noncommunicable diseases, said Friday that NCDs and their risk factors are increasing susceptibility to COVID-19 infection and the likelihood of worse outcomes, including in young people.  He said research from academics in several countries…

An independent panel appointed by the World Health Organization to review its coordination of the response to the COVID-19 pandemic will have full access to any internal U.N. agency documents, materials and emails necessary, the panel said Thursday as it begins the probe.   The panel's co-chairs, former Liberian President Ellen Johnson Sirleaf and former New Zealand Prime Minister Helen Clark, announced the 11 other members during a media briefing. They include Dr. Joanne Liu, who was an outspoken WHO critic while leading Medecins Sans Frontieres during the 2014-2016 Ebola outbreak in West Africa.     Also named to the panel are: Dr. Zhong Nanshan, a renowned Chinese doctor who was the first to publicly confirm human-to-human transmission of the coronavirus; Mark Dybul, who led the Global Fund to Fight…

New Zealand has recorded its first COVID-19 death since the end of May, health officials say, bringing the country’s total death tally from the virus to 23. In contrast, the United States continues to top the list of COVID-19 deaths with more than 186,000, and more than 6.1 million cases.Brazil follows the U.S. with just over 4 million cases and more than 124,000 deaths.   India comes in third with nearly 4 million cases and over 68,000 deaths. Berlusconi hospitalized Former Italian Prime Minister and leader of the Forza Italia (Go Italy!) party Silvio Berlusconi gestures during a rally ahead of a regional election in Emilia-Romagna, in Ravenna, Jan. 24, 2020.Silvio Berlusconi, Italy’s former prime minister, has been hospitalized for COVID-j19.  Doctors say the 83-year-old also has been diagnosed with the early stages of double pneumonia. His condition, however, is “not a cause for concern,” his Forza Italia party said in a statement.  His girlfriend, lawmaker Marta Fascina, has…

Two COVID-19 vaccines that could arrive as soon as November use a promising new technique that experts say speeds up the development process.  The new vaccines will be the first test to see if vaccines based on genetic code, rather than the germ itself, can be safe and effective. U.S.-based biotech company Moderna is developing one. The other is the product of a collaboration between German drugmaker BioNTech and U.S.-headquartered Pfizer.  FILE - The Pfizer company logo is seen at the company's headquarters in New York, Dec. 4, 2017.FILE - A sign marks an entrance to a Moderna, Inc., building, in Cambridge, Mass., May 18, 2020.All previous vaccines have triggered the immune system with dead or weakened versions of a germ or parts of it.

The U.S. space agency, NASA and aerospace firm Northrop Grumman Wednesday conducted a full-scale test of a rocket motor, known as a "Flight Support Booster" or "FSB-1,” that will power the first Artemis mission to the moon.During the test at Northrop Grumman's facility in Promontory, Utah, the 47-meter booster motor was anchored to the ground horizontally, and fired for just over two minutes, producing 1.6 million kilograms of thrust.NASA and Northrop Grumman will use data from the test to evaluate the motor’s performance using potential new materials and processes that can be incorporated into future boosters. NASA has contracted Northrop Grumman to build boosters for future rocket flights.Researchers Discover First Intermediate-size Black HoleAstronomers say they have discovered evidence of the first intermediate-size black hole, created by merger of two smaller…

The U.S. Centers for Disease Control and Prevention has confirmed that it has informed public health officials in all 50 states and several large cities to be prepared to distribute a coronavirus vaccine by November 1, two days before the presidential election.The McClatchy news service was the first to report Wednesday that the CDC had sent out a four-page memo on August 27 for health departments to draft vaccination plans by October 1  “to coincide with the earliest possible release of COVID-19 vaccine.” The 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.Fauci's take on potential vaccine News of the CDC memo coincided with remarks made Wednesday by Dr. Anthony…

It seems possible, though how often it happens isn't known. Researchers in Hong Kong  recently reported evidence of a person who got the coronavirus a second time, months after an initial infection. The finding has not yet been published in a journal. But scientists said the 33-year-old man had mild symptoms the first time and none the second time, suggesting his immune system may have provided some protection against serious illness even if it could not prevent a reinfection. His more recent infection was detected through screening and testing at the Hong Kong airport, and researchers said genetic tests revealed different strains of the virus. Several other possible cases have been reported, including a U.S. man who was sicker the second time than the first. Even if people can get…

The U.S. Centers for Disease Control and Prevention sent guidelines on August 27 to all 50 states, U.S. territories and several large cities, telling them to be prepared to distribute a coronavirus vaccine by Nov. 1, two days before the presidential election, according to several media reports Wednesday.In a four-page memo sent to governors in August, the CDC told health departments to draft vaccination plans by October 1 “to coincide with the earliest possible release of COVID-19 vaccine.”McClatchy first reported news of the letter, which other media then reported.The CDC declined to comment on the letter, Bloomberg reported Wednesday.States “in the near future” will receive permit applications from McKesson Corp., the firm that has contracted with the CDC to distribute vaccines to sites including state and local health departments and…

A Mexican court will later this week hear a case brought on by 15 young people demanding the government of President Andres Manuel Lopez Obrador set out clear policies on climate change, documents show. Lopez Obrador is under increased pressure to help mitigate the effects of climate change. The plaintiffs from the state Baja California filed a legal stay of proceedings, known locally as amparo, before a district court in administrative matters, several documents related to the case show. In it, the youths, aged 17 to 23, demand clearer regulations and public policies derived from the country's existing General Law on Climate Change and the Mexican constitution, the documents showed. All of the documents, which have not been made public, were provided by a representative of the plaintiffs. Demonstrators march during the global protest on climate…
