“The U.S. Food and Drug Administration has given the green light to two biotechnology companies for clinical trials that will transplant organs from genetically modified pigs into people with kidney failure. If successful, these studies could lead to the broader use of cross-species transplantation, a dream of medical scientists for centuries…

The United Therapeutics study, which is expected to begin midyear, will start with six patients who have been on dialysis for at least six months but do not have other serious medical problems. There will be a three-month waiting period between each transplant so that doctors can learn from the outcomes.

If the first six transplants are successful, the trial will expand to include up to 50 participants in what is called a phaseless trial — a type of study that combines the traditional Phase 1, Phase 2 and Phase 3 trials and can lead directly to approval…

The eGenesis trial will begin with three patients with kidney failure who are unlikely to receive a human organ within five years.”

“China said Tuesday it was expanding its visa-free transit policy, allowing Americans and other eligible foreign travelers to stay in parts of the country as long as 240 hours, or 10 days, as officials try to attract more overseas visitors.

China’s National Immigration Agency announced the measure, which is effective immediately, on its WeChat account, saying passport holders from 54 countries are eligible. They include countries in Europe, Latin America and Asia, as well as the United States and Canada.

Previously, travelers could stay in China visa-free for as long as 72 to 144 hours depending on where they visited, as long as they continued on to a third country or region.”

“Americans can now renew their passports online, bypassing a cumbersome mail-in paper application process that often caused delays.

The State Department announced Wednesday that its online renewal system is now fully operational, after testing in pilot programs, and available to adult passport holders whose passport has expired within the past five years or will expire in the coming year. It is not available for the renewal of children’s passports, for first-time passport applicants for renewal applicants who live outside the United States or for expedited applications.”
