Unraveling the mystery of Texas" cryptic freshwater blobs—expert discusses bryozoans
Despite what you may initially think, the gelatinous blobs occasionally found clinging to structures in ponds or reservoirs are not the nefarious, otherworldly creatures seen in classic science fiction or horror films......»»
Scientists take atomic look at a protein complex that grants access to our DNA
To transcribe the information contained in our genes or to repair the dozens of breaks that occur daily in our DNA, our enzymes must be able to directly access the DNA to perform their functions. However, in the cell nucleus, this access is limited b.....»»
Coupling excitons to polaritons for better solar cells and higher intensity LEDs
In solar cells and light-emitting diodes, maintaining the excited state kinetics of molecules against annihilation is a race against time. These systems need to strike a careful balance between different processes that lead to loss of energy and thos.....»»

Scientists "cautiously optimistic" about AI"s role in drug discovery
The human body contains at least 20,000 different proteins, often called the "workhorses of the cell" because of their role in keeping cells healthy. Each protein consists of a unique string of amino acids that affects its shape and function—or dys.....»»
Researchers demonstrate mechanism that may have stabilized the first RNA molecules
The origins of life remain a major mystery. How were complex molecules able to form and remain intact for prolonged periods without disintegrating? A team at ORIGINS, a Munich-based Cluster of Excellence, has demonstrated a mechanism that could have.....»»
