Satellite imagery cited by Pepel suggests the Belgorod Reservoir dam in Russia was damaged on July 19, likely from a Ukrainian strike, with a roughly 30-meter spillway breach and a compromised crest road. Floodwaters are flowing into the Nezhegol River, threatening Shebekino, and Pepel warns the damage could be more serious than the 2025 repair."
In naturally aged mice, hippocampal-adjacent white matter accumulates a microglial population that co-expresses senescence and disease-associated microglia (DAM) markers, notably GAL3/Lgals3, defining a white matter–exclusive SenBrain-DAM state enriched in fimbria. Spatial profiling across IMC, GeoMx DSP and CosMx SMI reveals multiple age-related trajectories from homeostatic microglia to DAM and senescent states, with GAL3+ cells marking a prominent age-excluded subset. Systemic senotherapeutics targeting p16 (AP20187) or BCL2 (venetoclax) reduce GAL3+ DAM markers, lower p16, and restore microglial organization and morphology toward a youthful pattern in aged fimbria, including reduced APOE+ GAL3+ cell density and altered microglia–fiber tract alignment. These findings suggest a partially reversible senescence–DAM microglial phenotype in aging white matter and highlight GAL3/Lgals3 as a potential biomarker and target to mitigate white matter–related cognitive decline.
A new Science Advances study models building three dams across the 51-mile Bering Strait to see if closing the passage could strengthen the Atlantic Meridional Overturning Circulation (AMOC) and delay its collapse under warming. Results suggest that under lower CO2 and a mildly weakened AMOC, closure could help maintain AMOC, but with a much weaker AMOC it could accelerate decline; the plan would disrupt wildlife, Indigenous communities, fisheries, and shipping, and outcomes are highly uncertain, necessitating more modeling. Regardless, experts say reducing greenhouse gas emissions remains the most reliable way to protect AMOC.
A Kona Low storm dumped extreme rainfall across Oahu and Maui, triggering a statewide flood watch and mass evacuations—more than 230 people rescued and thousands displaced—as authorities warn that saturated ground means even less rain could trigger dangerous floods; a dam near Honolulu is at risk of collapse, and damages could exceed $1 billion, marking Hawaii’s worst flood in 20 years.
Hawaii is experiencing its worst flooding in more than 20 years, with heavy rain threatening the Wahiawa dam and prompting evacuations for about 5,500 people on Oahu’s North Shore; officials warn of possible dam failure as more rain is forecast, and Governor Green says storm costs could exceed $1 billion, with federal aid being pursued.
Heavy rains on Oahu’s north shore have forced evacuations for about 5,500 residents, with Waialua residents urged to leave due to the risk of road failure. No deaths have been reported yet, but around 200 people have been rescued and 10 hospitalized for hypothermia. A 120-year-old Wahiawa dam is considered at imminent risk of failure, prompting further evacuations and a major mobilization of the Hawaii National Guard and other responders. Gov. Josh Green says damage could exceed $1 billion, and more rain is expected in coming days.
Hawaii endures its worst flooding in two decades as heavy rains inundate areas north of Honolulu, forcing evacuations for thousands and prompting warnings about a vulnerable 120-year-old dam, with more rainfall expected to follow.
Oahu remains under a flash flood warning with a flash flood emergency on the North Shore as a Kona-low storm system dumps heavy rain statewide. Authorities say Wahiawa Dam is at imminent risk of failure, prompting evacuations downstream in Waialua and Haleiwa and the opening of multiple shelters. The Hawaii National Guard, Coast Guard, and Army personnel are assisting with rescues and evacuations, and power outages have affected thousands in evacuation zones. Forecasters warn more heavy rain is possible, and a statewide flood watch and additional advisories extend through the weekend, with Maui also under flood advisories and Hawaii Island facing a winter-storm watch for the peaks.
A 120-year-old dam on Oahu is considered at risk of imminent failure as severe rains flood northern areas, prompting evacuation orders for more than 4,000 residents, activation of the Hawaii National Guard, and shelter evacuations, with no deaths reported so far.
Two powerful storms drenched Hawaii, pushing Wahiawa Dam on Oahu toward potential failure from overtopping and prompting evacuation orders for Waialua and Haleiwa, affecting about 4,000 residents. The 1906, 9,200-acre-foot earthen dam, owned by Dole and forming Lake Wilson, has a spillway that could be overwhelmed in a major flood. Officials say the risk is evolving, with flood watches in effect and more rain expected; Governor Josh Green urged residents to evacuate as state offices closed except emergency management.
Heavy rains on Oahu prompted evacuation orders for more than 4,000 residents as officials warned the 120-year-old Wahiawa Dam could fail, triggering flash floods, rescues, and shelter relocations; the Hawaii National Guard was activated and some areas saw 8–12 inches of rain in a single night.
Africa's largest dam has raised concerns downstream along the Nile River, highlighting tensions over water resources and regional stability.
Russian hackers reportedly took control of a Norwegian dam in April, causing a temporary flood, marking Norway's first official attribution of such an attack to Moscow, amid increasing concerns over cyber espionage and sabotage by pro-Russian actors in Norway.
Russian hackers reportedly took control of a Norwegian dam in Bremanger, highlighting increasing cyber threats from Russia aimed at demonstrating capabilities rather than causing damage, with Norway's police chief warning of ongoing threats and vulnerabilities in critical infrastructure.
China has begun constructing the world's largest hydropower dam in Tibet's Yarlung Tsangpo canyon, sparking concerns from India and Bangladesh over potential environmental impacts and control of trans-border rivers, with critics warning it could threaten downstream livelihoods and regional stability.
