Two people in safety glasses observe a scientific experiment through a glass window in a lab, with equipment and handwritten notes visible inside the fume hood. Two researchers in lab coats and goggles work with outdoor scientific equipment near a modern building. A person in protective gear descending the stairs next to LZ's central detector, the time projection chamber, in a surface lab clean room before delivery underground. Wind turbine at sunrise with sunflowers in the foreground. Daniela Leitner, a person with short brown hair wearing a white cardigan over a blue top and a gold necklace, photographed outdoors. A digital illustration of light green rod-shaped bacteria floating in front of an uneven dark green surface suggestive of the gut lining. Kristin Persson holding a molecule model. Two scientists in hard hats working on the 2x2 prototype detector for the DUNE near detector. White R&D 100 Awards logo on a dark green background. A digital illustration showing a strand of DNA (red and blue) wrapped around histone proteins (gray). The DNA strand comprising each chromosome is tightly packed into clusters of wrapped histones to compress the long molecule and streamline separation of copied chromosomes during cell replication. The strand is carefully unwound by different enzymes, including TIP60, to make it accessible for duplication and gene expression.
