Team provides novel baseline data on leopard seals, mysterious apex predators of Antarctica

“Begonia” the largest leopard seal ever recorded by Baylor marine biologist, Sarah Kienle and her research team. Credit: Baylor University Baylor University marine biologist Sarah Kienle, Ph.D., has always been fascinated by leopard seals. These prehistoric, reptilian-looking seals are often portrayed as scary villains in movies such as “Happy Feet” and “Eight Below,” but little … Read more

Team reveals surprising details of crucial energy-producing enzyme

Nebraska’s Oleh Khalimonchuk has helped unravel long-obscured details about the formation of cytochrome c oxidase (left), an enzyme critical to producing the energy that powers all sorts of life-sustaining operations in the cell. Credit: Scott Schrage / University Communication and Marketing A new study from the University of Miami and University of Nebraska-Lincoln has upended … Read more

Research team models moving ‘washers’ that help DNA replicate

A helicase protein model created at Rice University shows a before-and-after of how the six-sided ring moves along DNA to split double strands into single strands in response to ATP hydrolysis during replication. Credit: Shikai Jin Knowing the structure of a complex biological system isn’t nearly enough to understand how it works. It helps to … Read more

Research team first to develop 3D structure of twinkle protein

Credit: AA Riccio, NIEHS Researchers from the National Institutes of Health have developed a three-dimensional structure that allows them to see how and where disease mutations on the twinkle protein can lead to mitochondrial diseases. The protein is involved in helping cells use energy our bodies convert from food. Prior to the development of this … Read more

Team discovers new plant gene reprogramming mechanism

Credit: CC0 Public Domain Researchers Albert CairĂ³ and Karel Riha of the Central European Institute of Technology (CEITEC) and their colleagues have discovered a previously unknown mechanism that is responsible for reprogramming gene expression in plants during the transition period when one cell differentiates into another one. The mechanism occurs at the end of meiosis, … Read more

Team troubleshoots asteroid-bound Lucy spacecraft across millions of miles

Team invents new anticoagulant platform, offering hope for advances for heart surgery, dialysis, other procedures

RNA-DNA nanofibers have been designed to bind and inactivate thrombin and due to their size have a prolonged circulation in bloodstream. This induced anticoagulation process can be reversed by the kill switch mechanism that also results in production of smaller complexes for accelerated renal excretion.
