Jenn Kauffman, who has a background inand labor studies, was a semifinalist for the fellows program this year and had been waiting to hear if she would be accepted. As layoffs were announced, she began to worry if it would continue.

“I worked really hard and wanted that satisfaction to see it through,” she said.On Feb. 19, during the week finalists would have been named, the Trump administration announced an executive order cutting the program.Kauffman, 45, said she was crushed by the decision and worries that the mass layoffs and dissolution of the fellows program will forever change public service.

“It’s so easy to decimate something but so much harder to rebuild,” she said. “And I worry that the incredibly talented people who may have been my cohort or colleagues are going to go elsewhere, and there will be an incredible brain drain. It’s such a loss for the American people.”Sydney Smith, 28, said many of the fellows were shocked at being let go because they came in to the government with ideas on how to make it more efficient.

Smith studied chemistry as an undergraduate student at Willamette University in Oregon before going on to study accounting at George Washington University. She heard about the presidential fellows program but was skeptical she would get in because of the low acceptance rate.

After she made it as a finalist in 2023, she started working forIt’s not clear exactly how Alzheimer’s and other types of dementia form. But certain viruses that sneak inside the nervous system – especially members of the herpes family including the chickenpox virus -- have long been suspected of adding to genetic and other factors that make people more vulnerable.

, doctors at Boston’s Brigham and Women’s Hospital reported that an episode of shingles could raise someone’s risk of dementia by about 20%.Partly, it’s because that virus can cause inflammation, bad for organs including the brain. It also can directly infect blood vessels in the brain, causing clots and impeding blood flow, said Colorado’s Nagel, a risk both for strokes and for dementia.

More intriguing, her lab also discovered shingles can spur formation of a sticky protein called amyloid that’s one of the hallmarks of Alzheimer’s.Adults who get recommended vaccines tend to have other brain-healthy habits including exercising and a good diet, which made it hard to prove an extra benefit.
