Albeni Falls Dam plans fish lock and transport system for threatened bull trout (opens the original)
Read excerpt
Engineers in northern Idaho are designing a unique upstream fish passage facility for the Albeni Falls Dam on the Pend Oreille River. Built in 1955, the dam that is 90 feet tall blocked the access of the native migratory fish species to their natural cold-water spawning grounds. This project will incorporate the use of a fish lock mechanism operated together with special transport trucks. The double-pass approach targets connecting threatened bull trout to 750 miles of upstream habitat. Albeni F
Kamoa-Kakula solar project pairs 233 MWp of panels with 526-MWh battery storage (opens the original)
Read excerpt
At the Kamoa-Kakula copper mine in the Democratic Republic of Congo, a huge solar power plant was commissioned for full commercial operation. In collaboration with CrossBoundary Energy, the power plant is a hybrid system that combines 360,000 high-efficiency back-contact solar modules with a large battery storage capacity of 526 megawatt-hours. With 233 megawatts of capacity at peak generation, the power plant supplies 30 megawatts of baseload power to mining industries with a 95% annual availab
Amateur astronomers across several countries helped confirm gas giant TOI-4465 b (opens the original)
Read excerpt
Astronomers at the University of New Mexico detected a dense gas giant exoplanet around 400 light-years away from Earth. The first orbiting data from NASA’s Transiting Exoplanet Survey Satellite picked up 12 hours of dimmed starlight, but to prove the existence of the exoplanet, they needed another full orbit. This task could not be undertaken by just one observatory. It took the efforts of 24 citizen scientists in 10 different countries to observe TOI-4465 b for 12 hours. The discovery of the c
Eastern Iowa balloon measured record calendar-day moisture before 4–6 inches of overnight rain (opens the original)
Read excerpt
A dense column of water vapor was captured by an atmospheric balloon released from Davenport, Iowa. The sounding exceeded the daily precipitable-water record for that calendar day. The pressure front then moved the dense column of moisture into eastern Iowa, releasing convective systems from midnight until dawn. These training storms produced four to six inches of rain, flooding low-lying roads and pushing the longest continuous rainfall streak in Dubuque since 1880 to its peak. The weather ball
WISE volunteers identified more than 3,000 candidate brown dwarfs near the Sun (opens the original)
Read excerpt
Volunteers analyzing space telescope data have identified thousands of dim objects in the neighborhood of our Sun. By analyzing the infrared data acquired by NASA’s WISE (Wide-field Infrared Survey Explorer), the volunteers identified 3,006 motion-confirmed brown dwarf candidates. Brown dwarfs are compact substellar bodies often referred to as ‘failed stars. If these candidates are confirmed through follow-up spectroscopy, this decade-long research would more than double the number of known brow
