    The image shows a series of suprachiasmatic nucleus slices expressing click beetle green in AVP neurons and click beetle red in non-AVP neurons. As time progresses (spiraling into the image), the AVP (green) and non-AVP (red) neurons luminesce together rhythmically, thanks to the intact genetic clocks of the AVP neurons and exchange of neuronal signals.

    A new mouse model helps researchers study the roles of cell types in keeping time inside the body. UT Southwestern scientists have developed a genetically engineered mouse and imaging system that lets them visualize fluctuations in the circadian clocks of cell types in mice...

    Researchers from Kobe University and the National Institute of Technology, Oshima College have conducted a detailed reanalysis of image data from Voyager 1, 2 and Galileo spacecraft in order to investigate the orientation and distribution of the ancient tectonic troughs found on Jupiter’s moon Ganymede. They discovered that these troughs are concentrically distributed across almost the entire surface of the satellite. This global distribution indicates that these troughs may be actually part of one giant crater covering Ganymede.

    Based on the results of a computer simulation conducted using the “PC Cluster” at the National Astronomical Observatory of Japan (NAOJ), it is speculated that this giant crater could have resulted from the impact o...

    The ultra-thin clear coatings are made with a new spray-on method that is fast, cost-effective and scalable.

    New transparent spray-on coatings are conductive, cost-effective and rival the performance of current industry standards. A simple method for making clear coatings that can block heat and conduct electricity could radically cut the cost of energy-saving smart windows and heat-repelling glass.

    The spray-on coatings developed by researchers at RMIT University in Melbourne, Australia, are ultra-thin, cost-effective and rival the performance of current industry standards for transparent electrodes.

    Combining the best properties of glass and metals in a single component, a transparent electrode is a highly conductive clear coating that allows visible light through.

    The coati...

    Analysis of NASA lander seismograph data reveals boundaries from crust to core. Using data from NASA’s InSight Lander on Mars, Rice University seismologists have made the first direct measurements of three subsurface boundaries from the crust to the core of the red planet.

    “Ultimately it may help us understand planetary formation,” said Alan Levander, co-author of a study available online this week in Geophysical Research Letters...
