For scientists studying the ocean, finding the right data can sometimes be as challenging as figuring out what to do with it. Want to know seafloor depth, the location of underwater mountains or sea surface temperatures? The information exists, but it can take considerable time and computer coding to pull it together from different sources and get it into the proper format.

Scientists have long been interested in cellular nanodiscs, tiny particles made from natural cell membranes that mimic many of the functions of living cells. While previous studies demonstrated the therapeutic potential of nanodiscs for drug delivery, detoxification and vaccines, one fundamental question remained unanswered: How does size influence how well they work?

Water isn't always as it seems. Under extreme conditions, such as those found on other planets, it has been discovered to change its atomic structure, giving it the means to alter its appearance and other properties.

Superconductivity has many important practical applications, including creating powerful magnets used in high-resolution medical scans, transporting electricity efficiently and building ultrasensitive measuring devices. Until now, understanding exactly what lay behind this unique phenomenon at high temperatures has eluded scientists over many decades.
