Between the end of February and mid-August, funding ceased for 383 studies that were testing treatments for conditions including cancer, heart disease and brain disease.

On Monday, scores of scientists at the agency sent their Trump-appointed leader a letter titled the Bethesda Declaration, challenging “policies that undermine the NIH mission, waste public resources, and harm the health of Americans and people across the globe.”

The lawsuit filed in federal court in Boston challenges the Trump administration, the Department of Health and Human Services and the National Institutes of Health over efforts to reduce funding that goes to so-called indirect costs — including lab, faculty, infrastructure, and utility costs.

Monday’s announcement from the NIH’s $1.15 billion RECOVER project comes amid frustration from patients who’ve struggled for months or even years with sometimes-disabling health problems.

A study from the National Institutes of Health last month showed women who use chemical hair relaxers or straighteners may have a higher risk of the cancer.

The survey found that 11% of young adults reported using marijuana on a daily basis in 2021 and 43% had used it in the past year. About 8% of young adults reported using substances such as LSD, PCP and psychedelic mushrooms in the past year, up from just 3% in 2011.

After decades of scientists basically using male laboratory animals for medical research, the National Institutes of Health is ending the gender bias practice in research. The shift, as published in the journal Nature, should help minimize side effects and dosage miscalculations not discovered until after products hit the market.
