Researchers at George Mason University have developed a urine test to identify tuberculosis cases, per New Scientist. The method — which worked successfully on 48 people with TB —provides a diagnosis within just 12 hours, compared to days for existing skin and sputum culture tests.

How it works: The test can detect a sugar on the surface of TB bacteria that is present in low concentrations in the urine of those infected.

Why it matters: TB killed about 1.7 million people last year. "In around 40 per cent of cases, the infection isn’t identified until symptoms become obvious," writes Andy Coghlan in the New Scientist. The urine test, which the researchers hope to have publicly available within three years, could allow for the rapid identification of the disease.

Pelosi on state of coronavirus stimulus talks: "It's a chasm"

Democrats and the Trump administration remain "miles apart" on negotiations over a coronavirus stimulus deal, House Speaker Nancy Pelosi (D-Calif.) said on Wednesday.

Driving the news, via Axios' Dion Rabouin: Congress' failure to renew enhanced unemployment measures for millions of Americans at the end of July is already affecting consumer spending patterns, holding down retail purchases and foot traffic, economists at Deutsche Bank say.

U.S. threatens to veto UN peacekeeping in Lebanon over Hezbollah concerns

The Trump administration is threatening to veto a resolution to extend the UN's long-standing peacekeeping mission in southern Lebanon if its mandate isn't changed, Israeli and U.S. officials tell me.

Why it matters: The U.S. is the main funder of the UN Interim Force in Lebanon (UNIFIL), which has an annual budget of $250 million. The veto threat is a tactical move, and part of a broader effort to put pressure on Iran and its proxy in Lebanon, Hezbollah.
