‘Science at the Smithsonian’ gallery: 165 years of scientific achievement

‘Science at the Smithsonian’ gallery: 165 years of scientific achievement

On Aug. 10, 1846, U.S. President James K. Polk signed the legislation that established the Smithsonian Institution as a trust administered by a Board of Regents and a Secretary of the Smithsonian. Joseph Henry, the first secretary of the Smithsonian (1846-1878), strove to develop the Smithsonian into the nation’s first major research institute for science. [...] [...more]

Research on tungara frogs may be applicable to hearing loss/attention deficits in humans

Research on tungara frogs may be applicable to hearing loss/attention deficits in humans

A new study has revealed information about the way tungara frogs in the tropical rain forest hear, sort, and process sounds which is very similar to the way humans do. The knowledge could be applicable to communication disorders associated with hearing loss and attention deficits or difficulties. [...more]

Genetic study confirms American crocodiles and critically endangered Cuban crocodiles are hybridizing in the wild

A new genetic study by a team of Cuban and American researchers confirms that American crocodiles are hybridizing with wild populations of critically endangered Cuban crocodiles, which may cause a population decline of this species found only in the Cuban Archipelago. [...more]

This fossil represents a new genus and species of extinct aneuretopsychid, Jeholopsyche liaoningensis, recently described in a paper in the journal ZooKeys by Conrad Labandeira of the Smithsonian’s National Museum of Natural History, and Dong Ren and ChungKun Shih of the College of Life Sciences, Capital Normal University, Beijing. The aneuretopsychidae are a family of long-proboscid insects that lived in Asia from the Late Jurassic to Early Cretaceous. The paper documents the first formal record of fossil Aneuretopsychidae in China. The new fossils reveal previously unknown and detailed structure of the mouthparts, antennae, head, thorax, legs and abdomen of this distinctive insect lineage.
