Molecular bioscientist Jared Ellefson of the University of Texas at Austin has created a way for RNA to "proofread" copies of genetic information for the first time. This artist's interpretation of the process shows RNA making DNA copies in...

This is a drawing of the skeleton of Alamosaurus sanjuanensis compared to a 180cm (5ft 11") human. Based on reconstructed skeleton exhibited at the Perot Museum of Nature and Science, in Dallas, Texas. Colored bones indicate the institutional collection...
This image shows cone photoreceptors (green) in a slice from a mouse retina. A majority of the photoreceptors (97%) in the retina are rods (black). The black layer on top of the photoreceptors is retinal pigment epithelium.Credit: Jung-Woong Kim Early...
A new study is a "major step forward" in the understanding of water-protein interactions. It answers a question that's been dogging research into protein dynamics for decades.Credit: Jo McCulty Scientists are getting closer to directly observing how and why water...
A new imaging technique allows researchers to image both the position and orientation of single fluorescent molecules attached to DNA.Credit: Maurice Y. Lee, Stanford University Researchers have developed a new enhanced DNA imaging technique that can probe the structure of...
Birth by C-section, exposure to antibiotics and formula feeding slow the development and decrease the diversity of a baby's microbes through the first year of life. That is the finding of a study led by researchers from NYU Langone...

The first fossil skull of Castoroides ohioensis found in 1845 alongside the skull of a modern beaver. Credit: New York State Museum A few snippets of protein extracted from the fossil of an extinct species of giant beaver are opening...
The figure depicts one of the X-ray crystal structures solved by the research team. Shown is the serine protease urokinase-type plasminogen activator (green) in complex with a Camelid antibody fragment (orange). The Camelid antibody fragment display an unusual inhibitory...
The collection of avian brains that the scientists analyzed. For each species, the total number of neurons (in millions) in their brains is shown in yellow, the number of neurons (in millions) in their forebrains (pallium) is shown in...
