Parrots and songbirds have evolved distinct brain mechanisms, study shows
When humans learn to speak a language, we learn to produce new vocalizations and use them flexibly for communication, but how the brain is able to achieve this is an important but largely unanswered question, according to Zhilei Zhao, Klarman Fellow.....»»
Study suggests climate played a crucial role in human migration from Africa
About 6 million years ago, in the deep forests of eastern Africa, something spectacular happened. Chimpanzees, our closest relative in the animal kingdom, evolved in one direction, while our earliest ancestors continued in another......»»
Environmental engineers suggest that anaerobic digestion could be used to clean cattle manure, produce fuel
Chemicals—from antibiotics used to keep livestock healthy to pesticides that shield crops from insects and other pests—play an important role in modern agriculture. However, many of these substances accumulate in cow manure used as fertilizer, wh.....»»
DNA analysis of bat droppings shows astonishingly high number of insect species
Adequate food supply is a fundamental need and requirement for survival. To protect a species, it is often very helpful to know what that species prefers and frequently consumes. Through the analysis of DNA traces in the droppings of a Leisler's bat.....»»

Snake skulls show how species adapt to prey
By studying the skull shapes of dipsadine snakes, researchers at The University of Texas at Arlington have found how these species of snakes in Central and South America have evolved and adapted to meet the demands of their habitats and food sources......»»
Fish brains may provide insight into the molecular basis of decision-making
How do animals make decisions when faced with competing demands, and how have decision making processes evolved over time? In a recent publication in Biology Letters, Tina Barbasch, a postdoctoral researcher at the Carl R. Woese Institute for Genomic.....»»
Political ideology affected how COVID-19 news was consumed, study finds
During the COVID-19 pandemic, the speed with which available health and safety information evolved was novel to most people around the world. To assess how the public handled the changing guidance, an international research team compared information.....»»

Dwarf galaxies use 10-million-year quiet period to churn out stars
If you look at massive galaxies teeming with stars, you might be forgiven for thinking they are star factories, churning out brilliant balls of gas. But actually, less evolved dwarf galaxies have bigger regions of star factories, with higher rates of.....»»
First comprehensive look at effects of 2020–2021 California megafires on terrestrial wildlife habitat
The only thing constant is change—isn't that how the saying goes? We know that wildlife in western forests evolved with changing habitats and disturbances like wildfire. Each species responds differently, some benefiting from openings, others losin.....»»
