Scientists and doctors are exploring whether existing treatments for HIV, Ebola and malaria could combat the coronavirus, the Los Angeles Times reports.

Driving the news: The antiviral remdesivir protected monkeys from MERS, another coronavirus, both before and after exposure, the National Institute of Health announced Thursday.

The medication, made by Gilead, has been used in experiments to fight Ebola, and has also been used to keep SARS from replicating in animals.

  • Two other drugs for Ebola and malaria are being used on Chinese patients — one to disrupt covis-19's genetic material and the other to keep the coronavirus from penetrating cells, respectively.
  • Doctors are also looking at HIV medication that could block an enzyme the virus needs to mature, per LAT.

Why it matters: An anti-viral or immunotherapy that's already been proven safe could be a faster solution to slowing down infections. But their effectiveness against the coronavirus still has to be tested.

California Gov. Gavin Newsom (D) extended a drought emergency declaration to cover 41 of the state's 58 counties on Monday.

Why it matters: Most of California and the American West are experiencing an "extreme" or "exceptional" drought, per the U.S. Drought Monitor. Newsom and other officials are concerned California could experience a repeat of the catastrophic 2020 wildfire season.

Nine children were among 20 Palestinians killed in Israeli airstrikes after Hamas fired dozens of rockets at Jerusalem for the first time since 2014 Monday, per AP and Reuters.

The big picture: The rockets come after escalating violence in Jerusalem has injured 250 Palestinians and several Israeli police officers during protests over the planned evictions of Palestinian families from their homes that began Friday.

Pelosi's Republican playbook

As Republicans fight among themselves, House Speaker Nancy Pelosi (D-Calif.) is showing the myriad ways she deals with the GOP herself.

Between the lines: We've seen Pelosi cut opponents off at the knees, like she did with President Trump, or pretend to forget their names, as she did to Sen. Ron Johnson (R-Wis.). Now she's feeding oppo research against her House counterpart, Minority Leader Kevin McCarthy (R-Calif.), so others can use the same harsh rhetoric to frame the Republicans as the party of dysfunction.
