The ultimate goal of a lumpectomy is to remove all the cancerous tissue from a person's breast while saving as much of the healthy tissue as possible. But that's even harder than it sounds. Without the ability to look at tissue under a microscope, it's currently impossible to tell whether the area surrounding a tumor contains cancerous cells or…

What counting Florida butterflies can tell the world about climate change
Every year when summer temperatures sizzle and the rest of South Florida heads inside, a dedicated crew of citizen scientists ventures into the buggy heat to do an increasingly difficult job: count butterflies. For the last quarter century, the North American Butterfly Association has tallied the nation’s population of butterflies three times a year, including…

Genetic analysis of New World birds confirms untested evolutionary assumption

Genetic analysis of New World birds confirms untested evolutionary assumption
Biologists have always been fascinated by the diversity and changeability of life on Earth and have attempted to answer a fundamental question: How do new species originate? An implicit assumption in the discipline of speciation biology is that genetic differences between populations of animals and plants in a given species are important drivers of new…

South African cave yields yet more fossils of a newfound relative
Probing deeper into the South African cave system known as Rising Star, a subterranian maze that last year yielded the largest cache of hominin fossils known to science, an international team of researchers has discovered another chamber with more remains of a newfound human relative, Homo naledi. The discovery, announced May 9, 2017 with the…
