Scientists are proposing a new way to fight solid cancer tumors by interfering with blood vessels surrounding them to shut off the tumor's supply of oxygen and nutrients. The new research could lead to a therapy that combines two different mechanisms used by immune cells to halt the growth of cancer tumors.

The background: The immune system is the most powerful weapon against diseases that we know. Medical researchers have triggered the immune system to fight cancer cells floating in the blood stream, but not successfully on solid tumors.

How it might work: T-cells are a special type of immune cell. They produce both interferon gamma and something called tumor necrosis factor (TNF). Working together, TNF can burst the blood vessels around a cancer, which allows interferon gamma to cut off the blood supply. The researchers tested it on genetically modified mice in a clinical lab setting. It didn't kill the cancer cells, but it kept the disease from progressing by stopping the growth of tumors.

Speaker Nancy Pelosi (D-Calif.) on Monday unveiled House Democrats' new $2.2 trillion coronavirus relief proposal.

Why it matters: Negotiations with the Trump administration have stalled since the House passed its $3 trillion HEROES Act in May. The pared-down bill, which is $200,000 smaller than Democrats' most recent proposal, is part of Pelosi's last-ditch effort to strike a deal with the White House.

Ex-officer pleads not guilty to charges related to Breonna Taylor killing

The former Louisville police officer charged with three counts of wanton endangerment in connection with the raid that led to the fatal shooting of Breonna Taylor, an unarmed Black woman, pleaded "not guilty" on Monday, the Courier Journal reports.

The big picture: The announcement of charges against Brett Hankison, who was fired from the department in June, set off nationwide protests last week. None of the officers involved in the raid were indicted on homicide or manslaughter charges related to Taylor's death.
