Politicians have mocked, belittled, and cut federally funded research for decades, but funding basic science has a long history of lifesaving discoveries.

For years, post-traumatic stress disorder (PTSD) has been studied primarily in people who experience trauma firsthand. But what about those who witness it — military veterans, first responders, health care workers, or bystanders to violence — who constitute 10 percent of all PTSD cases?

New research from Virginia Tech, published in PLOS ONE, reveals that witnessing trauma triggers unique brain changes, distinct from those caused by experiencing trauma firsthand. The study is the first to shed light on the molecular differences between directly acquired PTSD and bystander PTSD and could pave the way for changes in how the disorders are treated.

The agency froze most spending above $1. Government researchers now struggle to carry out basic functions of their jobs.

Wealthy, educated Americans face far fewer health risks

Mathematicians from New York University and the University of British Columbia have resolved a decades-old geometric problem, the Kakeya conjecture in 3D, which studies the shape left behind by a needle moving in multiple directions.

In their ongoing efforts to push the boundaries of quantum possibilities, physicists at WashU have created a new type of “time crystal,” a novel phase of matter that defies common perceptions of motion and time.

Researchers found that adding city waste products to local farms promoted a healthy soil microbiome and improved how tomatoes taste.

When the FDA announced in January, before President Joe Biden’s term ended, that it would ban a dye called red dye No. 3 in food and ingested drugs, the federal agency cited just one 1987 study on rats to support its action.

National Institutes of Health officials have urged scientists to remove all references to mRNA vaccine technology from their grant applications, two researchers said, in a move that signaled the agency might abandon a promising field of medical research.
