Moulting and breeding cost birds a lot of energy. So it would make sense for the animals to do these two things at separate times. Yet slaty brush finches…
How do organisms evolve into individuals that are distinguished from others by their own personal brain structure and behaviour? Scientists in Dresden, Berlin,…
A variety of methods have previously been developed with the goal of attaching CO2 to various organic molecules to convert them into intermediate products for…
In healthy human cells, the genome tends to be in a highly ordered state: DNA is neatly packed into precisely 46 chromosomes. In cancer cells, the picture is…
Scientists in Dresden, Berlin, Münster, and Saarbrücken have now taken a decisive step towards clarifying this question. Using mice as an animal model, they…
From the several pandemics generally called 'pestilences' three are historically recognized as due to plague, but only for the third pandemic of the 19th to…
Children born with rare, inherited conditions known as Congenital Disorders of Glycosylation, or CDG, have mutations in one of the many enzymes the body uses…
By monitoring the behavior of a class of cells in the brains of living mice, neuroscientists at Johns Hopkins discovered that these cells remain highly dynamic…
University of Washington engineers and NanoFacture, a Bellevue, Wash., company, have created a device that can extract human DNA from fluid samples in a…
Enzymes could break down cell walls faster – leading to less expensive biofuels for transportation – if two enzyme systems are brought together in an…
Humans are only capable of hearing sounds of 20kHz maximum, dropping to around 12-15kHz as we age, and even dolphins, known exponents of ultrasound, can't…
In a study to be published May 7 in mBio®, the online open-access journal of the American Society for Microbiology, scientists at Emory University School of…
An entomologist at the University of California, Riverside discovered a new wasp species in Russia and named it after the university, commonly abbreviated as…
Instead of sequencing each gene one at a time, the team used a technique called whole-exome sequencing that deciphers nearly all human genes simultaneously.”My…
Kansas State University researchers Jeroen Roelofs, assistant professor, and Chingakham Ranjit Singh, research assistant professor — both in the Division of…
Researchers at the Monell Center and collaborators have identified a protein that is critical to the ability of mammals to smell. Mice engineered to be lacking…
