Weekend #Plankton Factoid 🦠🦐
Heliozoans are a group of amoeboid protists found commonly in both fresh and saltwater. They were termed sun-animalcules due to their spherical shape and distinctive radiating microtubules, which support axiopods used to capture food and facilitate movement. Some will also capture symbiotic algal cells which provide energy through photosynthesis. Heliozoa is &quo…

Charged wormholes can be long-lived
Ellis-Bronnikov wormholes suffer from an unstable radial mode. Here we investigate the evolution of the unstable mode(s) for charged wormholes. We show that the instability remains in the presence of charge, but exhibits a very fast decrease to zero, suggesting that wormholes that approach a near-extremal metric could be long-lived. For so-called supercritical wormholes, two purely imaginary unstable modes merge and continue with degenerate imaginary parts and opposite real parts. By analogy, w…

Project Severe Weather Archive of the Philippines (SWAP) Part 2: Baseline Climatology of Close Proximity Soundings in Hailstorm Environments across Luzon, Philippines
The environments of severe thunderstorms that produced hail were examined using 171 proximity soundings (2005-2024) archived in the 3rd Data Release of Project SWAP. These soundings were categorized based on their geographical occurrence into three hail-prone environments across Luzon, Philippines. For each case, key parameters describing instability, vertical wind structure, and moisture were calculated to assess their relationship to hail formation. The probability of hail occurrence, express…
