A new study found that a rare brain defect, which can lead to strokes and seizures, is caused by specific bacteria that live inside the gut.

What's next: Brain surgery is the only treatment after the defect is discovered. With these new findings, researchers hope that they will be able to use antibiotics and a fecal transplant to prevent the brain defects in children who inherit the mutated genes. It is too soon to say whether that approach will work though, another researcher not involved in the study told the New York Times.

The experiment: The scientists deleted defect-linked genes in mice and they developed malformations in the brain. When the researchers moved their lab to a different building, the mice no longer developed the lesions. They determined that the needle they used to inject the mice in the old building exposed them to a bacteria, leading them to develop lesions, connecting the microorganisms and the disease.

President Trump's outdoor campaign rally in Portsmouth, N.H., slated to take place on Saturday, was postponed on Friday due to weather from Tropical Storm Fay, a senior White House official confirmed to Axios.

The state of play: Press Secretary Kayleigh McEnany told reporters on Air Force One that the event would take place in "a week or two" instead. The outdoor rally — which had encouraged the use of face masks — was scheduled after sparse attendance at Trump's indoor comeback to the campaign trail in Tulsa.

Biden's big economic plan plays it down the middle for Democrats

Joe Biden yesterday laid out the broad strokes of his economic policy platform, which seemingly is designed to not freak out centrists and not piss off progressives.

Why it matters: Biden has a better-than-even shot of becoming the next president, which means his tax plans could become everyone's tax bills.
