Activists in Cameroon held events and marches for Thursday's World Toilet Day, calling on authorities to provide more public bathrooms. Cameroonian authorities say 60% of its 25 million people lack toilets, fueling the spread of diseases such as cholera and dysentery.School authorities at Yaoundé’s Government Primary School Efoulan say they have close to 2,000 children and teachers but only five toilets, which are often unusable as they run short of water and toilet paper.The Cameroon Association to Improve Hygiene organized this and similar events in 30 schools in the capital to mark this year’s World Toilet Day.The group’s head, Edmond Kimbi, said hundreds of their members also marched in Yaoundé and coastal cities to demand more and better public toilets."It is actually too regrettable that schools and universities have very…

The National Science Foundation announced Thursday that it would close the huge telescope at the renowned Arecibo Observatory in Puerto Rico in a blow to scientists worldwide who depend on it to search for planets, asteroids and extraterrestrial life. The independent, federally funded agency said it was too dangerous to keep operating the single-dish radio telescope — one of the world's largest — given the significant damage it recently sustained. An auxiliary cable broke in August, tearing a 100-foot hole in the reflector dish and damaging the dome above it. Then on November 6, one of the telescope's main steel cables snapped, leading officials to warn that the entire structure could collapse. NSF officials noted that even if crews were to repair all the damage, engineers found the structure would still be unstable in the…

Just as the coronavirus pandemic began to take hold, in February, four people set sail for one of the most remote places on Earth – a small camp on Kure Atoll, at the edge of the uninhabited Northwestern Hawaiian Islands.There, more than 1,400 miles from Honolulu, they lived in isolation for eight months while working to restore the island's environment. Cut off from the rest of the planet, their world was limited to a tiny patch of sand halfway between the U.S. mainland and Asia. With no television or internet access, their only information came from satellite text messages and occasional emails.Now they are back, emerging into a changed society that might feel as foreign today as island isolation did in March. They must adjust to wearing face masks, staying…

The head of Germany's disease control agency said Thursday that while the coronavirus infection rate in the country remains serious, there are signs a partial lockdown is working.Germany implemented restrictive measures in early November to curb a nationwide surge in cases, closing bars, restaurants and other leisure venues but keeping schools and shops open.Speaking to reporters in Berlin, Robert Koch Institute chief Lothar Wieler said the number of new infections has since plateaued, with 22,609 reported on Thursday - roughly the same number as a week ago. He said the fact they are not rising is good news but cautioned that it was too early to say if this is a trend.Wieler said the overall number of cases is still too high, and there is a risk that hospitals may…

Thursday brought further good news from the global effort to produce a safe and effective vaccine against the coronavirus that causes COVID-19.  A report published in the prestigious medical journal The Lancet says that a potential vaccine developed by British pharmaceutical giant AstraZeneca in collaboration with the University of Oxford was safe and produced a strong immune response in both younger and older participants.  The two-dose vaccine was given to 560 healthy adult volunteers in a second-stage clinical trial, including 240 volunteers 70 years of age and older.  Dr. Maheshi Ramasamy, a  University of Oxford researcher and co-author of the study, described the antibody and T-cell responses in the older volunteers as “robust.”  Pfizer Says Its Coronavirus Vaccine is 95% EffectivePfizer to seek approval within days for emergency use of vaccine COVID-19…

The World Health Organization has officially declared an end to the Ebola outbreak in Democratic Republic of Congo’s Equateur Province, nearly six months after the first cases were reported. Health officials are hailing the end of this outbreak as a milestone and cause for celebration.  Combating Ebola in the remote, heavily forested region posed numerous logistical challenges, not least of which was reaching communities scattered across this geographically vast area and then gaining their trust.Bob Ghosn is head of the International Federation of Red Cross and Red Crescent Societies Ebola Response Operation in the DRC   Speaking on a telephone line from Goma, he tells VOA tackling Ebola in itself is difficult enough.   But tackling two epidemics, Ebola and COVID-19, at the same time has proven to be a nightmare.“It also made…

Thousands of demonstrators rallied Wednesday in central Berlin to protest the parliamentary vote that would give Chancellor Angela Merkel’s government powers to enforce restrictions aimed at curbing the spread of COVID-19.Germany's lower and upper houses of parliament are due to vote and pass laws Wednesday that could allow the government to impose restrictions on social contact, rules on mask-wearing, drinking alcohol in public, shutting shops and stopping sports events.   Although most Germans accept the latest limited lockdown to tackle a second wave of the virus, a minority of right-wing critics say the law gives the government too much power. The far-right Alternative for Germany (AfD) has even compared the measures to the Enabling Act of 1933 that paved the way Hitler's Nazi dictatorship.  Germany Sees Signs for Cautious Optimism…

The World Health Organization's emergencies program director said Wednesday that vaccines alone would not end the COVID-19 pandemic and would do nothing to stop the current global surge in coronavirus infections.Mike Ryan made the comments during a virtual question-and-answer session from the agency’s headquarters in Geneva.His comments came the same day that pharmaceutical company Pfizer and its German partner BioNTech announced that final results from the late-stage trial of their COVID-19 vaccine showed it was 95% effective.The companies said they had the required two months of safety data and would apply for emergency U.S. authorization within days.On Monday, Moderna released preliminary data for its vaccine, showing similar effectiveness.Ryan said the world would have to get through this current wave of COVID-19 infections without vaccines, which he said were not the…

The pharmaceutical company Pfizer said Wednesday that its coronavirus vaccine is 95% effective and caused no serious side effects as it plans to seek federal approval for the vaccine’s emergency use.Pfizer disclosed the results after a final analysis of the vaccine’s Phase 3 trial, which also revealed it protects older people most at risk of dying from COVID-19, the disease caused by the coronavirus.The American pharmaceutical giant’s announcement came a week after it first revealed promising preliminary findings, and days before it plans to formally ask the federal government to approve the vaccine for emergency use.5 Things to Know About Pfizer's Coronavirus Vaccine Early results look great, but questions remain Pfizer has not yet released detailed information about the trial and the results have not been scrutinized by independent experts.Pfizer…

Iota continues to pound Nicaragua with strong winds and heavy rains even after weakening from a hurricane to a tropical storm. As of late Tuesday night, the National Hurricane Center in Miami said Iota was carrying maximum sustained winds of 65 kilometers an hour on a path towards Tegucigalpa, Honduras.  Forecasters say Tropical Storm Iota will dump between 7 to 20 kilometers of rain on a stretch of Central America from southern Nicaragua to southern Belize overnight, leading to “significant, life-threatening flash flooding and river flooding,” along with mudslides in higher areas. The storm is expected to weaken to a tropical depression through the night before dissipating sometime Wednesday.A woman sits near her house damaged the passing of Hurricane Iota, in Puerto Cabezas, Nov. 18, 2020.Iota made landfall Monday on the northeastern…

An agreement announced Tuesday paves the way for the largest dam demolition in U.S. history, a project that promises to reopen hundreds of miles of waterway along the Oregon-California border to salmon that are critical to tribes but have dwindled to almost nothing in recent years. If approved, the deal would revive plans to remove four massive hydroelectric dams on the lower Klamath River, creating the foundation for the most ambitious salmon restoration effort in history. The project on California's second-largest river would be at the vanguard of a trend toward dam demolitions in the U.S. as the structures age and become less economically viable amid growing environmental concerns about the health of native fish. Previous efforts to address problems in the Klamath Basin have fallen apart amid years of legal sparring…

A group of major U.S. utilities, Tesla, Uber and others said on Tuesday they are launching a new group to lobby for national policies to boost electric vehicle sales. The new Zero Emission Transportation Association wants to boost consumer electric vehicle (EV) incentives and encourage the retirement of gasoline-powered vehicles. It also advocates for tougher emissions and performance standards that will potentially enable full electrification by 2030. Under President Donald Trump, the White House rejected new tax credits for electric vehicles as it proposed to kill existing credits and made it easier to sell gas-guzzling vehicles. President-elect Joe Biden promises new tax incentives, including new rebates to buy EVs and a dramatic expansion of charging stations for electric vehicles – policy measures automakers have long advocated. "We can own the electric vehicle market –…

The World Health Organization’s 194 member states have agreed to push for the global elimination of cervical cancer, a disease that every year affects 570,000 women and kills more than 300,000. A new strategy to accelerate the elimination of cervical cancer was adopted at this year’s World Health Assembly.Cervical cancer is a vaccine-preventable disease and curable if detected early and adequately treated. Health officials say the tools are available to eliminate this disease, the fourth most common cancer among women globally.   WHO’s three-point strategy calls for all girls to be vaccinated for HPV or human papillomavirus before age 15. It says women should be screened twice between the ages of 35 and 45 and those found to have the cancer should receive treatment. WHO’s assistant director-general, Princess Nothemba Simelela, says new…

Hurricane Iota made landfall along the northeastern coast of Nicaragua late Monday night and flash flooding and landslides are expected across Central America. The National Hurricane Center said Iota struck Nicaragua as a Category 4 storm, with winds of 210 kilometers per hour. Many people hunkered down in shelters while the Nicaraguan government evacuated thousands of residents in low lying coastal areas ahead of the storm. One resident in the seaside town of Bilwi, business owner Business owner Adán Artola Schultz, described the sound of metal structures banging and buckling in the wind as “like bullets” to the Associated Press.  Jason Bermúdez, a university student from Bilwi, told AP a lot of houses have lost their roofs, fences and fruit trees that got knocked down. Bermúdez said “(W)e will never forget this year.” “The situation is exacerbated by the fact that Iota is making landfall in almost the exact same location that category 4 Hurricane Eta…

The Trump administration is moving to finalize the sale of controversial oil drilling leases in a wildlife refuge in Alaska.A notice from the Bureau of Land Management posted on the federal register is listed as “unpublished” as of Monday, but it calls for nominations on the lease tracts considered for the oil sale. Oil drilling in the sensitive Arctic National Wildlife Refuge (ANWR) was banned for decades before a 2017 reversal by the Trump administration.In an executive order signed in April 2017, Trump reversed the Obama administration's decision to prohibit oil and gas drilling in the Arctic waters off Alaska.The White House said 90 billion barrels of oil and 327 trillion cubic feet of natural gas are buried off the U.S. coastline but that 94% of the area is off limits. President-elect…

Last week the World Health Organization hosted its annual summit known as the World Health Assembly to outline new policies and priorities, but a controversy involving Taiwan ended up also drawing renewed attention on how Beijing’s politics continue to influence the WHO.During the summit, which was hosted on the WHO official Facebook page, WHO moderators appeared to censor comments that contained words related to Taiwan or that implied the coronavirus originated in China. Several Taiwanese media reported that the WHO Facebook page blocked any Taiwan-related comments that included "Taiwan" or "Taiwan can help."After coming under criticism, the WHO said it was facing an “onslaught” of cyberattacks during the summit by activists using words including “Taiwan” and “China.” The group said it applied content filters to improve moderators’ ability to monitor conversations.…

Experts at the World Health Organization (WHO) say the news Monday of another COVID-19 vaccine candidate is encouraging but more information is needed and, as new virus cases surge around the world, it is no time to be complacent.At their regular COVID-19 news briefing in Geneva, WHO officials reacted to the news from U.S. pharmaceutical company Moderna that its vaccine candidate tested at better than 90% efficacy.WHO Chief Scientist Soumya Swaminathan said that level of efficacy in this vaccine, as well as the Phizer/BinNTech vaccine candidate announced last week, is very encouraging.WHO Chief Says Vaccine Alone Will Not End the PandemicTedros tells executive board that testing, vaccine will complement other tools, not replace themBut, she said, there are many questions remaining about the duration of protection they provide, the impact…

The high-pitched whine of a mosquito is annoying, but scientists have developed an app that uses that sound to detect dangerous mosquitoes.Mosquitoes kill hundreds of thousands of people each year by spreading microbes that cause diseases such as malaria, dengue fever and yellow fever. But researcher Haripriya Vaidehi Narayanan says anyone with a cellphone can help tackle these diseases by using the Abuzz app to identify mosquitoes. "If they see a mosquito around us, they just open the phone, open up the app, point their phone towards the mosquito and hit the record button," said Narayanan, who started working on the project as a graduate student at Stanford University. She's now in the Department of Immunology at the University of California Los Angeles. "So then, when the mosquito flaps its wings and…

The European Commission, the European Union’s administrative branch, announced  Monday a deal with to purchase 405 billion doses of a potential coronavirus vaccine from German bio-tech company CureVac. The announcement comes just days after EU officials announced a similar deal with German company BioNTech and U.S. pharmaceutical giant Pfizer for an initial 300 million doses of the vaccine candidate they jointly produced, which, they say, has proven 90 percent effective against COVID-19 in late-stage testing. European Commission President Ursula von der Leyen told reporters the deal with CureVac is, of course, conditional on their vaccine proving to be safe and effective.  Von der Leyen said the fifth CureVac is fifth company the alliance has contracted with a for its COVID-19 vaccine portfolio.FILE - A sign marks the headquarters of Moderna Therapeutics, which…

Portions of Central America are bracing for the arrival of Hurricane Iota which the National Hurricane Center says has strengthened into a dangerous Category 4 hurricane.  The meteorologists warn, however, that Iota could transform into a “catastrophic Category 5 hurricane” as it moves over the Caribbean before it slams into Colombia, Nicaragua and Honduras by Monday night. The forecasters say Iota is expected to deliver “potentially catastrophic winds, life-threatening storm surge and extreme rainfall impacts.”    Iota is moving with maximum sustained winds of 230 kilometers per hour as it heads toward much of the same area devastated by Hurricane Eta earlier this month.  ...

Giant, aging cables that support one of the world's largest single-dish radio telescopes are slowly unraveling in this U.S. territory, pushing an observatory renowned for its key role in astronomical discoveries to the brink of collapse.The Arecibo Observatory, which is tethered above a sinkhole in Puerto Rico's lush mountain region, boasts a 1,000-foot-wide (305-meter-wide) dish featured in the Jodie Foster film "Contact" and the James Bond movie "GoldenEye." The dish and a dome suspended above it have been used to track asteroids headed to Earth, conduct research that led to a Nobel Prize and helped scientists trying to determine if a planet is habitable."As someone who depends on Arecibo for my science, I'm frightened. It's a very worrisome situation right now. There's a possibility of cascading, catastrophic failure," said astronomer…

In an unassuming house in rolling hills east of the Hungarian capital, a small family firm is helping oil the wheels of the world’s big pharmaceutical companies on the path to a coronavirus vaccine. Biologist Noemi Lukacs, 71, retired to Szirak, her birth village, to establish English & Scientific Consulting (SciCons) and manufacture a genetic sensor so sensitive that a few grams can supply the entire global industry for a year. “We produce monoclonal antibodies,” Lukacs told Reuters in the single-story house where she was born, now partly converted into a world-class laboratory. The white powder ships worldwide from here, micrograms at a time. “These antibodies recognize double-stranded RNA [dsRNA],” she explained. DsRNA is a byproduct of viruses replicating, so its presence signals the presence of a live virus, long useful in virus-related…
