Because of strict visa policies, promotions to attract international tourists have not been as effective as expected, according to many businesses. Enterprises have made huge investments to welcome back tourists, but such illogical visa policies may slow down the tourism recovery pace. Being confused and facing difficulties Many travel companies in Da Nang City told Tuoi Tre (Youth) newspaper that visa policies for foreign tourists were still their biggest concern. Before the COVID-19 outbreak, Vietnam offered the visa waiver policy for citizens of many countries and the normal visa approval period was three to five days (visas which were valid for 30 days). However, the list of countries whose citizens are entitled to Vietnam’s visa waiver policy has been shortened and the visa processing period has been lengthened, putting enterprises at a disadvantage. Cao Tri Dung, chairman of the Da Nang Tourism Association, said that after the COVID-19 pandemic, the number of … [Read more...] about Strict visa policies hinder international guests from visiting Vietnam

WASHINGTON -- After some four years probing Mars' interior, NASA's InSight lander will likely retire this summer as accumulated dust on its solar panels saps its power. The lander will, however, leave behind a legacy of data that will be tapped by scientists around the world for years to come, helping to improve our understanding of planet formation, NASA said, while announcing on Tuesday the imminent end to InSight's science operations. Equiped with an ultra-sensitive seismometer, InSight recorded more than 1,300 "marsquakes," including a magnitude 5 quake on May 4, the largest so far. But around July, the seismometer will be turned off. The lander's energy level will then be checked about once a day, and some pictures may still be taken. Then by the end of 2022, the mission will be completely stopped. The cause: the accumulation over months of Martian dust on the lander's two solar panels, each measuring about seven feet (2.2 meters) wide. InSight, which is already … [Read more...] about End of the line nears for NASA InSight Mars lander

Rising COVID-19 cases are driving up the use of therapeutics, with Pfizer Inc's oral antiviral treatment Paxlovid seeing a 315% jump over the past four weeks, U.S. health officials said on Tuesday. The increase in U.S. cases and hospitalizations is starting to affect recommendations on behavior, with New York City, the nation's most populous city, advising stricter mask usage but stopping short of new mandates. Apple has scrapped return to office plans. "Increasingly, we'll see this virus hit people who are substantially older, frail, have underlying illnesses, or are distinctly immunocompromised," said Dr. William Schaffner, infectious disease expert at Vanderbilt University Medical Center in Nashville. "But we now have better treatments and many of those people will leave the hospital vertically rather than horizontally." The United States is averaging nearly 97,000 new cases a day, up from about 73,000 a week ago, according to a Reuters tally. Cases have been gradually … [Read more...] about As U.S. COVID-19 cases rise, so does demand for antivirals

Vietnam does not place much emphasis on achieving high results in vovinam at SEA Games 31 , said … [Read more...] about Vovinam makes comeback at SEA Games 31
