Hickory dickory dock, this nucleus could make a good clock.
A special variety of the element thorium hosts an atomic nucleus that could be used to keep time, scientists say. In a first, researchers have measured a type of decay of this thorium nucleus that releases a single particle of light. The measurement of the energy released in the decay is. The improved energy measurement could galvanize work toward the first nuclear clock, which would follow in the footsteps of atomic timepieces.
, which are already such powerful tools that they’re used in everything from GPS satellites to experiments that test whether fundamental laws of physics hold true . Kraemer and colleagues measured the energy released when the thorium-229 nuclei decayed, jumping down in energy from its higher energy state. First, the team had to get thorium-229 into that high-energy state, which is called an isomer. One way to do that is to start from another element that can decay into the thorium isomer.

The GUARDIAN system-a GNSS upper atmospheric real-time disaster information and alert network - GPS SolutionsWe introduce GUARDIAN, a near-real-time (NRT) ionospheric monitoring software for natural hazards warning. GUARDIAN’s ultimate goal is to use NRT total electronic content (TEC) time series to (1) allow users to explore ionospheric TEC perturbations due to natural and anthropogenic events on earth, (2) automatically detect those perturbations, and (3) characterize potential natural hazards. The main goal of GUARDIAN is to provide an augmentation to existing natural hazards early warning systems (EWS). This contribution focuses mainly on objective (1): collecting GNSS measurements in NRT, computing TEC time series, and displaying them on a public website ( https://guardian.jpl.nasa.gov ). We validate the time series obtained in NRT using well-established post-processing methods. Furthermore, we present an inverse modeling proof of concept to obtain tsunami wave parameters from TEC time series, contributing significantly to objective (3). Note that objectives (2) and (3) are only introduced here as parts of the general architecture, and are not currently operational. In its current implementation, the GUARDIAN system uses more than 70 GNSS ground stations distributed around the Pacific Ring of Fire, and monitoring four GNSS constellations (GPS, Galileo, BDS, and GLONASS). As of today, and to the best of our knowledge, GUARDIAN is the only software available and capable of providing multi-GNSS NRT TEC time series over the Pacific region to the general public and scientific community.
