Hepatitis B and C found a foe in biotech and medical researchers spearheaded or funded by a Chilean biochemist.

Why it matters: The work and research fostered by Pablo D. Valenzuela led to a groundbreaking vaccine-making technique and the treatment of those with hepatitis B or C, which each affect more than 1.5 million people worldwide every year, according the World Health Organization.

Details: Valenzuela, along with William Rutter and Edward Penhoet, founded the biotech firm Chiron in 1981.

  • With Valenzuela as head of research and development, scientists at Chiron in 1989 named the hepatitis C virus, which had puzzled doctors and researchers for years.
  • That research was awarded the Nobel Prize in Physiology or Medicine last year.

In 1986, Chiron accomplished what’s been called a “milestone” and “a medical biotechnology landmark": the creation of the first approved recombinant vaccine.

  • The mechanism, patented by Valenzuela for hepatitis B, “clones” a virus so the immune response can be triggered with particles that don’t have the actual disease agent.
  • Until then, vaccines had mostly been developed with dead viruses, which made them difficult to produce since they sometimes required plasma from patients that was hard to get.
  • In several parts of the world, including the U.S., people can now be safely and effectively vaccinated against hepatitis B from infancy.

Biden's ambassador nominee: "China is not an Olympian power"

President Biden's nominee to serve as ambassador to China delivered a stark assessment of the challenges the U.S. faces in confronting Beijing, but stressed that the rising superpower is "not all-powerful" and the West retains "substantial" advantages.

The big picture: Nicholas Burns, a retired career diplomat and former U.S. ambassador to NATO, used his confirmation hearing Wednesday to echo the growing bipartisan consensus that China poses "the greatest threat to the security of our country and the democratic world" in the 21st century.

Scoop: U.S. and Israel to form team to solve consulate dispute

The U.S. and Israel are planning to form a joint team to hold discreet negotiations on the reopening of the U.S. Consulate in Jerusalem, Israeli officials say.

Why it matters: The consulate handled relations with the Palestinians for 25 years before being shut down by then President Donald Trump in 2019. Senior officials in Israeli Prime Minister Naftali Bennett's government see the consulate issue as a political hot potato that could destabilize their unwieldy coalition.

Driving the news: Cruz, 23, pleaded guilty at a hearing on Wednesday to 17 murder counts and 17 counts of attempted first-degree murder for carrying out the deadly shooting.
