Shining a light on the effects of habituation and neural adaptation on the evolution of animal signals
A new paper published in The Quarterly Review of Biology examines the possible effects of two properties of receiver playing fields documented in studies of animal psychology—habituation and neural adaptation—on the efficacy of mate choice signal.....»»
Unveiling rare diversity: The origin of heritable mutations in trees
What is the origin of genetic diversity in plants? Can new mutations acquired during growth be passed on to seeds? INRAE scientists, in collaboration with CIRAD and the CNRS, have used the French Guiana forest as the setting for their research, leadi.....»»
The Golgi organelle"s ribbon structure is not exclusive to vertebrates, contrary to previous consensus
Researchers report February 29 in the journal Cell Reports that the Golgi ribbon, an organelle structure previously thought to be exclusive to vertebrates, is also present in animal taxa, including mollusks, earthworms, and sea urchins......»»
Scientists reveal how first cells could have formed on Earth
Roughly 4 billion years ago, Earth was developing conditions suitable for life. Origin-of-life scientists often wonder if the type of chemistry found on the early Earth was similar to what life requires today. They know that spherical collections of.....»»
Slimming down a colossal fossil whale
A 30 million year-old fossil whale may not be the heaviest animal of all time after all, according to a new analysis by paleontologists at UC Davis and the Smithsonian Institution. The new analysis puts Perucetus colossus back in the same weight rang.....»»
Drying without dying: Tracing water scarcity coping mechanisms from mosses to flowering plants
Imagine you find the dried-up remains of a once green and lush philodendron on your bookshelf and realize you can't remember the last time you watered your houseplants. You soak the soil with water, hoping you can breathe life back into its desiccate.....»»
A liking for licking—sex and social status influence social grooming among free-ranging feral cattle in Hong Kong
Unique insights into the social lives of cattle revealed in a new study by scientists at City University of Hong Kong (CityUHK) can enhance our understanding of animal behavior and welfare. The study suggests that sex and social status influence soci.....»»
New measurement captures clearer picture of our galaxy and beyond
With unique capabilities to track microwave energy fluctuations, a small observatory in the Andes mountains of northern Chile produced maps of 75% of the sky as part of an effort to measure the universe's origin and evolution more accurately......»»
Researchers describe new technological platform to accelerate drug development
Drug development is currently an extremely long, expensive and inefficient process. Findings generated in a lab are often very hard to replicate once translated into animal models or in humans......»»
Paleontologists discover a 240-million-year-old "Chinese dragon"
An international team of scientists from China, the U.S. and Europe has studied new fossils of the marine reptile Dinocephalosaurus orientalis. This research has made it possible to fully describe the bizarre, very impressive animal for the first tim.....»»
Male glass frogs that care for offspring found to have smaller testes
A small international team of animal behavior researchers has found that species of glass frogs whose males help care for offspring tend to have smaller testes than species whose males do not help care for offspring. In their study, published in the.....»»

Live imaging reveals key cell dynamics in 3D organ formation in Drosophila
Animal development requires successive changes in cell and tissue structures. To form complex 3D organs, cell shapes must adapt to support tissue morphogenesis. However, our understanding of how cellular structure changes are coupled with dynamic tis.....»»
Study shows orchid family emerged in northern hemisphere and thrived alongside dinosaurs for 20 million years
In a new study published in New Phytologist, scientists at the Royal Botanic Gardens, Kew, along with partners in Latin America, Asia and Australia, present an updated family tree of orchids, tracing their origins to the northern hemisphere some 85 m.....»»
