WASHINGTON, D.C.—The day after businessman and reality-TV star Donald Trump was sworn into office as the 45th president of the United States, hundreds of thousands of protestors descended on the nation’s capital allied loosely under the banner of marching for human rights. More than 200 similar marches had also been planned in cities across the country.

The Women’s March on Washington started near the Capitol and brought together a far-flung coalition of individuals and groups. Some of the protestors said they were here to stand in solidarity with efforts to protect the rights of women and their families. Others said they came to register their dismay about the Trump administration’s stance on certain scientific and medical issues—including climate change, reproductive rights and the future of research funding. Some researchers who joined the march said they were alarmed over what might happen to science in general with Trump at the helm.

Here is a sampling of photos and comments from protestors who said concerns about science brought them out:
