The White House released official portraits of President Donald Trump and Vice President Mike Pence Tuesday morning.According to an official press release from the White House, the portraits were produced by the Government Publishing Office. The photos will be distributed and displayed in the offices of federal agencies across the country.The walls of federal agencies have been a bit bare since Jan. 20, when former President Barack Obama's portrait was taken down in all federal agencies following the inauguration. A September story by the Washington Post reported that the Trump administration was slow to release an official portrait — Obama's portrait was released by March of his first year in office, President Bill Clinton's was released by June.The White House also says the photographs will be made available for sale to the public.  859

The United Kingdom says it will be the first to conduct COVID-19 vaccine human challenge trials.It's different than other vaccine studies. People will be deliberately infected with the virus, which speeds up the research process.Pending approval, the process will start in January at a London hospital. It will require about 90 healthy young adults between the ages of 18 and 30.The group 1 Day Sooner has recruited from all over the world, including 3,000 Britons.“If the vaccine works, then ideally, people don't get infected and if people do, then they will be closely monitored and treated, but because these are young and healthy people taking part in the trial, I think, researchers feel comfortable doing so because the risks of death are on par with something like kidney donation for people who are young and healthy,” said Abie Rohrig with 1 Day Sooner.Before researchers test the vaccine, they'll do a characterization study. That's where volunteers are infected by getting a vaccine to determine the right amount of virus to give during the trial.Because of the risk, 1 Day Sooner is advocating for the entire process to be made public.Results could come in May. Even though that's likely after other COVID-19 vaccines are licensed, it's still important because we need billions of doses and because of the unique data human challenge trials provide.“Researchers can understand how the virus works in the human body. They can understand the biological markers of immunity. In fact, much of our understanding of other types of coronaviruses come from challenge studies that were conducted in the 1960s in Britain,” said Rohrig.Human challenge volunteers are paid and monitored for at least a year after. 1722

The Trump administration is promising one of the largest fireworks displays in recent memory in Washington on July Fourth. It also plans to give away as many as 300,000 face masks to those who come down to the National Mall for the festivities, although they won't be required to wear them. This is despite concerns from D.C. Mayor Muriel Bowser, who warns that the plans run counter to established health guidelines. Interior Secretary David Bernhardt on Wednesday detailed President Donald Trump's plans for Independence Day in the nation's capital and said they include a mile-long detonation of 10,000 fireworks. Trump and first lady Melania Trump plan to host events on Saturday from the White House south lawn and from the Ellipse.Additionally, military planes will conduct flyovers in a handful of major cities along the East Coast as part of this year’s July Fourth celebration. The Pentagon says roughly 1,700 service members will support a salute to the “Great Cities of the American Revolution.” The flyovers will begin in Boston and proceed to New York City, Philadelphia and Baltimore. Washington has held an Independence Day celebration for decades, featuring a parade along Constitution Avenue, a concert on the Capitol lawn with music by the National Symphony Orchestra and fireworks beginning at dusk near the Washington Monument.President Donald Trump plans to kick off Independence Day festivities with a showy display at Mount Rushmore the day before. When he speaks at the Mount Rushmore, he’ll stand before a crowd of thousands of people who won't be required to socially distance or wear masks despite the coronavirus pandemic. The event will include fighter jets thundering over the 79-year-old stone monument in South Dakota’s Black Hills and the first fireworks display there since 2009.Public health experts are warning of the risk that it could help the coronavirus to spread. And others say the fireworks will put the forest around the monument at risk to wildfires. 2003

The weekend didn't make things any easier for students of Marjory Stoneman Douglas High School: Parents had to lay teen children to rest; the family who had taken in shooter Nikolas Cruz said they didn't know they were living with a "monster;" and a tweet from President Donald Trump seemed to infuriate an already-angry student body.The students promised action in the wake of the massacre that left 17 of their classmates and teachers dead. They're headed to Tallahassee, Florida, to speak to legislators about school safety and gun control this week, and they have school walkouts and a march scheduled in the coming months.Meanwhile, Anthony Borges, 15, continued his recovery. He's one of four patients who remain hospitalized after Wednesday's massacre in Parkland, Florida. He was shot five times, according to the Broward County Sheriff's Office.  868

The smoke from dozens of wildfires in the western United States is stretching clear across the country — and even pushing into Mexico, Canada and Europe. While the dangerous plumes are forcing people inside along the West Coast, residents thousands of miles away in the East are seeing unusually hazy skies and remarkable sunsets.The wildfires racing across tinder-dry landscape in California, Idaho, Oregon and Washington are extraordinary, but the long reach of their smoke isn’t unprecedented. While there are only small pockets in the southeastern U.S. that are haze free, experts say the smoke poses less of a health concern for those who are farther away.The sun was transformed into a perfect orange orb as it set over New York City on Tuesday. Photographs of it sinking behind the skyline and glinting through tree leaves flooded social media. On Wednesday, New Jersey residents described a yellow tinge to the overcast skies, and weather forecasters were kept busy explaining the phenomenon and making predictions as to how long the conditions would last.On the opposite coast, air quality conditions were among some of the worst ever recorded. Smoke cloaked the Golden Gate Bridge and left Portland and Seattle in an ashy fog, as crews have exhausted themselves trying to keep the flames from consuming more homes and even wider swaths of forest.Satellite images showed that smoke from the wildfires has traveled almost 5,000 miles (8,000 kilometers) to Britain and other parts of northern Europe, scientists said Wednesday.The current weather system, which favors a westerly wind across the higher levels of the atmosphere, is to blame for the reach of the smoke, experts explained.“We always seem, at times, to get the right combination of enough smoke and the upper level jet stream to line up to bring that across the country, so we’re just seeing this again,” said Matt Solum with the National Weather Service’s regional operations center in Salt Lake City, Utah. “It’s definitely not the first time this has happened.”There could be some easing of the haze this weekend as a storm system is expected to move into the Pacific Northwest and could affect the conditions that helped the smoke travel across the country. But Solum said there’s always a chance for more smoke and haze to shift around.“Just due to all the wildfires that are going on, this is likely going to continue for a while,” he said. “You might have ebbs and flows of that smoke just depending on how the upper level winds set up.”Kim Knowlton, a senior scientist with the Natural Resources Defense Council in New York City, said she woke up Wednesday to a red sunrise and more haze.She said millions of people who live beyond the flames can end up dealing with diminished air quality as it’s not uncommon for wildfire smoke to travel hundreds of miles.Although the health impacts are reduced the farther and higher into the atmosphere the smoke travels, Knowlton and her colleagues said the resulting haze can exacerbate existing problems like asthma and add to ozone pollution. 3070
