The US ambassador to Mexico was not invited to a meeting between senior White House adviser Jared Kushner and Mexican officials, including President Enrique Pe?a Nieto, a US official told CNN.Roberta Jacobson, a career diplomat who has more than 30 years of experience in the region, announced her retirement earlier this month effective in May. Her departure comes at a time when US relations with Mexico have been strained over issues related to trade and migration.Kimberly Breier, who was just nominated to be the new assistant secretary for Western Hemisphere -- a senior State Department position Jacobson previously held -- was with Kushner at the Wednesday meeting.The New York Times first reported that Jacobson was not at the meeting.The timing of the meeting came amid NAFTA negotiations and questions over President Donald Trump's tariff proposal. It also comes shortly after Kushner had his security clearance downgraded because he had not obtained his full clearance.  995

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 shortest day in what feels like the longest year has arrived. Monday is the Winter Solstice, the day each year when there is the least amount of sunshine in the Northern Hemisphere.The Winter Solstice is the official first day of winter, which lasts until March 20, 2021. It’s when the sun appears at its most southern position in the sky.If it has felt like the world has been getting darker and darker the last six months, that’s because it kind of has been. As the sun spent less and less time shining on the Northern Hemisphere.The closer a person is to the North Pole, the less time they will see the sun. People in Nome, Alaska will only have roughly 3 hours and 54 minutes of sunshine on Monday.There will now begin to be slightly more daylight each day until the Summer Solstice, which is on June 20, 2021.In the Southern Hemisphere, it’s the opposite: it’s the day each year with the most sunshine and marks the beginning of summer in places like Australia, Argentina and South Africa.Many traditional celebrations on the solstice were canceled this year because of the coronavirus pandemic. Including at the world famous Stonehenge, where there is usually a large annual celebration on the solstices. 1222
