Meet The Blind Birder Reimagining Accessibility In The Outdoors For many blind and low vision people, accessing outdoor spaces like parks can be challenging. Trails are often unsafe or difficult to navigate, signs don’t usually have Braille, guides generally aren’t trained to help disabled visitors, and so on. But nature recordist Juan Pablo Culasso, based in Bogata, Colombia, is changing that. He...

What’s Behind The Strange Slowing Of The Earth’s Core? Even though some days feel more chaotic than others, the rotation of the surface of the planet proceeds at a pretty constant rate—about one full rotation every 24 hours. But the rotational speed of the inner core is less stable, and has been known to shift over time. Now, researchers are reporting in the journal Nature Geoscience that accordin...

Why Are Gas Stoves Under Fire? If you were online at all last week, you probably encountered conversations about gas stoves.

Early Migration To North America Likely Wasn’t A One-Way Road The story of how early humans migrated to North America might not be as simple as we once thought. The prevailing theory was that ancient peoples traveled from Siberia to modern-day Alaska using the Bering strait as a land bridge. But new genomic research, published in Current Biology, reveals movement in the opposite direction, back to...

FDA Expands Pharmacy Options for Abortion Pills This week, the FDA finalized rules that would allow more retail pharmacies to stock and fill prescriptions for the abortion drug mifepristone .

How Redlining Shaped Baltimore’s Tree Canopy Redlining was pervasive in American cities from the 1930s through the late 1960s. Maps were drawn specifically to ensure that Black people were denied mortgages. These discriminatory practices created a lasting legacy of economic and racial inequality which persists today. Less obvious is how redlining has shaped nature and the urban ecosystem. A recent...
