An international group of vaccine experts have come out in opposition of providing booster shots of COVID-19 vaccines to the general population, an opinion that pushes back against increasing efforts in the United States and other nations battling a surge of new cases.In an essay published Monday in The Lancet medical journal, the experts say recent studies show the current vaccines in use around the world continue to provide strong protection against the virus despite the presence of the more contagious delta variant, especially against severe illness and hospitalization. The trend to provide booster shots of COVID-19 vaccines began after studies out of Israel suggested the two-dose Pfizer vaccine’s effectiveness had significantly decreased among elderly people who were inoculated at the beginning of this year. The data prompted Israel to begin administering booster shots to people 50 years of age or older.   The authors suggest that modifying the vaccines to match the specific COVID-19 variants is a better approach than providing extra doses of the original vaccine.   The authors include two leading scientists with the World Health Organization, Ana-Maria Henao-Restrepo and Soumya Swaminathan, and Dr. Marian Gruber and Dr. Philip Krause, two key officials in the U.S. Food and Drug Administration’s vaccine review office who are leaving their posts before the end of the year. The New York Times recently reported that Gruber and Krause are upset over the Biden administration’s recent announcement that booster shots would be offered for some Americans beginning next month, well before the FDA had time to properly review the data. The FDA is nearing a decision on whether to recommend COVID-19 vaccines for children under 12 years of age and booster shots of the current vaccines already approved for adult Americans. Both the FDA and the Centers for Disease Control and Prevention last month recommended a third shot of Pfizer or Moderna for some people with weakened immune systems.  FILE – World Health Organization Director-General Tedros Adhanom Ghebreyesus attends a news conference in Geneva.Tedros Adhanom Ghebreyesus, the director-general of the World Health Organization, recently implored wealthy nations to forgo COVID-19 vaccine booster shots for the rest of the year to ensure that low- and lower-middle-income countries have more access to the vaccine. Tedros had previously asked high and upper-middle income nations not to provide boosters until September.  British Prime Minister Boris Johnson is set to announce Wednesday that the government will provide COVID-19 vaccine booster shots for citizens 50 years of age and older in time for the upcoming winter months. Putin self-isolatingMeanwhile, Russian President Vladimir Putin is self-isolating after several members of his entourage tested positive for COVID-19, according to a statement by the Kremlin.   President Putin has tested negative for the virus, but has decided not to  travel to Tajikistan for upcoming security conferences, the statement added. He met Monday with Syrian President Bashar al-Assad and held a separate public event with several members of Russia’s Paralympic team.   Putin has been fully vaccinated against COVID-19 with the domestically-developed two-dose Sputnik V vaccine.  Some information for this report came from the Associated Press, Reuters and Agence France-Presse.

Researchers in Australia have developed new microscopic lasers that have a range of potential medical, surgical, industrial and military uses.   Researchers at the Australian National University (ANU) say “nanolasers” promise to be even more powerful than conventional technology. The technology uses laser light instead of electronics and is an approach called photonics. Nanolasers, they say, need only a small amount of energy to start shining. Instead of using mirrors that reflect light, the team has created a device that traps energy and prevents it from escaping. That power is harnessed and builds into a “strong, well-shaped” beam. Researchers say this overcomes a well-known challenge of nanolasers — “energy leakage.”   The project is a collaboration with academics at Korea University, and is published in the journal Nature Communications. The lead researcher is professor Yuri Kivshar, who says the beams would act like a torch, or flashlight, to guide a surgeon.   “Why do we need [it] smaller? Imagine you are doing [a] kind of operation inside of body [sic] and you are using optical fiber. So, optical fibers introduced inside of body will see only light, which inside there is basically nothing, so you need a kind of torch. This torch will lighten the place which you need to work on and that will be a kind of real torch effect,”  he said.Academics have said that while their nanolasers are not the smallest ever developed, they are among the most efficient and powerful.   According to the ANU study, the energy threshold at which the laser starts to work is about 50 times lower than any previously documented nanolaser.    The physicists believe the technology could have a range of applications in small devices, including hair removal, laser printing, night-time surveillance and the illumination of delicate surgery inside the body.

Four people are set to become the world’s first all-civilian crew to fly into Earth orbit when they blast off from NASA’s Kennedy Space Center Wednesday as space tourism takes its biggest leap yet.  Weather conditions are 70% favorable for Wednesday night’s scheduled launch of Americans Jared Isaacman, Hayley Arceneaux, Chris Sembroski and Sian Proctor from the U.S. spaceport’s historic Launch Pad 39A, which was used for the Apollo moon missions during the 1960s and 70s.  The four-member crew will fly into space aboard the Crew Dragon spacecraft built by SpaceX, the privately-run company which has begun sending astronauts to the International Space Station. The fully automated Crew Dragon spacecraft will take the crew to an altitude of 575 kilometers above the Earth’s surface, just above the current positions of both the ISS and the Hubble Space Telescope.   SpaceX said the four space tourists will “conduct scientific research designed to advance human health on Earth and during future long-duration spaceflights” before splashing down in the Atlantic Ocean near the Florida coast three days later.   The mission, dubbed Inspiration4, will be led by the 38-year-old Isaacman, a billionaire technology entrepreneur and founder of an online payment-processing company who is said to have paid SpaceX several million dollars for the flight. The 29-year-old Arceneaux is a childhood bone cancer survivor who has a titanium rod in her leg, which makes her the first person to fly in space with a prosthesis. Sembroski is a 42-year-old retired U.S. Air Force ballistic missile maintenance engineer who now works in the aviation industry, while 51-year-old Proctor is a geoscientist and community college professor who was a NASA astronaut finalist in 2009.  Sembroski and Proctor were selected through a nationwide search contest, while Arceneaux is flying as a representative of St. Jude Children’s Research Hospital in Memphis, Tennessee, where she was treated during her battle with cancer and now works as a physician’s assistant. Isaacman is using the flight to raise $100 million for St. Jude, and has pledged $100 million of his own money to the hospital. Isaacman’s flight will far exceed those of fellow billionaires Richard Branson and Jeff Bezos, who each took brief non-orbital flights to the edge of space aboard their own self-financed vehicles — Virgin Galactic and Blue Origin, respectively — earlier this year.      Some information for this report came from the Associated Press, Reuters and Agence France Presse.

The Atlantic storm dubbed Nicholas has been upgraded from a tropical storm to a hurricane as it heads towards the southeastern coast of Texas. The National Hurricane Center says Nicholas is about 30 kilometers southeast of Matagorda, Texas, carrying maximum sustained winds of 120 kilometers an hour, making it a Category 1 storm on the five-level scale that measures a storm’s maximum sustained wind speed and destructive potential. It is the sixth named hurricane of the 2021 Atlantic hurricane season. Nicholas, which has already begun to produce heavy rains and strong winds along parts of Texas and neighboring Louisiana, is expected to make landfall along the Texas coast before daybreak Tuesday morning. Forecasters expect the hurricane to travel along a northeastern path outside of the city of Houston before moving into Louisiana during the day. Forecasters have issued hurricane watches and warnings and storm surge warnings for several communities along the Texas coast, with the likelihood of life-threatening situations such as flash flooding. Nicholas is expected to produce between 15 and 30 centimeters of rain along the region into Wednesday. The National Hurricane Center also says there is a chance of “a tornado or two” along the upper Texas and southwest Louisiana coast through Tuesday morning. The flood-prone city of Houston was swamped by Hurricane Harvey in 2017, which dropped 152 centimeters of rain (60 inches) on the city over four days. “Listen to local weather alerts and heed local advisories about the right and safe thing to do, and you’ll make it through this storm just like you’ve had many other storms,” Texas Governor Greg Abbott said during a news conference in Houston Monday. Forecasters say Nicholas is likely to gradually weaken over the next two or three days. Some information for this report came from The Associated Press.

A World Bank report released Monday suggests climate change could force 216 million people across six regions to migrate within their countries in the next 30 years, with “hotspots” emerging within the next nine years unless urgent steps are taken. 
The “Groundswell Part 2” report examines how climate change is a powerful driver of migration within a nation because of its impact on people’s livelihoods through droughts, rising sea levels, crop failures and other climate-related conditions.  
The original Groundswell climate report was published in 2018 and detailed projections and analysis for three world regions: sub-Saharan Africa, South Asia and Latin America. “Groundswell 2” conducted similar studies on East Asia and the Pacific, North Africa, and eastern Europe and Central Asia. 
Both studies established different scenarios to explore potential future outcomes and identify internal climate in- and out- migration hotspots in each region — that is, the areas from which people are expected to move, and the areas to which they might go. 
The study suggests that by 2050, sub-Saharan Africa could see as many as 86 million internal climate migrants; East Asia and the Pacific, 49 million; South Asia, 40 million; North Africa, 19 million; Latin America, 17 million; and eastern Europe and Central Asia, 5 million. 
To slow the factors driving climate migration and avoid these worst-case outcomes, the report recommends a series of steps world leaders can take, including reducing global emissions in line with the goals established by the Paris 2015 climate agreement, and taking steps to better understand the drivers of internal climate migration, so appropriate policies to address them can be developed.

Britain’s chief medical officer (CMO), Professor Chris Whitty, recommended Monday that children between the ages of 12 and 15 be offered the COVID-19 vaccine, saying they would benefit from reduced disruption to their education. More than a week ago, Britain’s Joint Committee on Vaccination and Immunization, the panel that advises British health departments on immunization policies, issued a statement saying the “margin of benefit” to inoculating children of those ages was too small for them to recommend the government do so. Britain’s Chief Medical Officer for England Chris Whitty attends a remote press conference to update the nation on the COVID-19 pandemic, inside 10 Downing Street in central London on June 10, 2020.But Monday, Whitty, along with his counterparts from Scotland, Wales and Northern Ireland, told reporters they are recommending to their respective health ministers that the age group be given a single dose of the Pfizer-BioNTech vaccine. They have yet to decide on whether to give the students a second dose. Whitty stressed the vaccinations should be “an offer,” not a mandate, adding, “We do not think this is a panacea. This is not a silver bullet … but we think it is an important and potentially useful additional tool to help reduce the public health impacts that come through educational disruption.” Whitty said the CMOs have shared their recommendations with their ministers, and it is now up to the ministers to decide how to respond.  The United States, Israel and some European countries have rolled out vaccinations to children more broadly, putting pressure on the British government to follow suit. Britain has experienced more than 134,000 deaths from COVID-19, and a rapid start to its immunization rollout has slowed, with 81% of those over 16 receiving two vaccine doses. Some information in this report was provided by The Associated Press, Reuters, and Agence France-Presse.
