Tau proteins protect brains of kingfishers while diving: Study

Ever wondered what helps kingfishers dive without hurting their brains while if a human ever belly-flopped into a pool, water can be surprisingly hard and sometimes can lead to injuries as well. A team of researchers has found that it’s the magic of Tau proteins that help stabilise tiny

DNA from 93-year-old butterfly confirms the first US case of human-led insect extinction

Credit: Field Museum The Xerces blue butterfly was last seen flapping its iridescent periwinkle wings in San Francisco in the early 1940s. It s generally accepted to be extinct, the first American insect species destroyed by urban development, but there are lingering questions about whether it was really a species to begin with, or just a sub-population of another common butterfly. In a new study in Biology Letters, researchers analyzed the DNA of a 93-year-old Xerces blue specimen in museum collections, and they found that its DNA is unique enough to merit being considered a species. The study confirms that yes, the Xerces blue really did go extinct, and that insect conservation is something we have to take seriously.

Field Museum Scientists Use DNA to Unlock Extinction Mystery of Xerces Blue Butterfly

Was the elegy misguided? The Xerces status as a distinct species, as opposed to being a sub-population of another non-extinct butterfly, has been questioned by some for decades. In a new study published in Biology Letters, researchers at the Field Museum were able to put a definitive end to those doubts, confirming that the Xerces blue was indeed a unique species, albeit one now also confirmed as extinct. “It’s interesting to reaffirm that what people have been thinking for nearly 100 years is true, that this was a species driven to extinction by human activities,” said Felix Grewe, co-director of the Field’s Grainger Bioinformatics Center and the lead author of the Biology Letters paper on the project.
