Uganda
Deadly Bus Collision
At least 46 people were killed and many others injured in one of Uganda’s deadliest road accidents in recent years after two buses and two other vehicles collided early Wednesday on the Kampala-Gulu Highway near Kiryandongo. Police initially reported 63 deaths but later corrected the number, explaining that some unconscious victims were mistakenly counted among the dead. The crash occurred around midnight when two buses traveling in opposite directions attempted to overtake a lorry and a car, resulting in a head-on collision and a chain reaction involving other vehicles. President Yoweri Museveni expressed condolences and pledged financial support to the victims’ families. Road safety advocates say the tragedy highlights ongoing issues of speeding, poor infrastructure, and weak traffic law enforcement.

Nuclear Workers Furloughed
The U.S. National Nuclear Security Administration (NNSA), the Energy Department arm that manages the nuclear stockpile, will furlough about 1,400 employees and keep fewer than 400 on duty as the federal government shutdown stretches into a third week. The NNSA’s Office of Secure Transportation can operate until October 27, but assembly sites such as Pantex in Texas and Y-12 in Tennessee are shifting to minimum-safe status, with contractors warning that limited work could halt as early as October 28 when funds are exhausted. This is the first time since the agency’s creation in 2000 that NNSA has furloughed federal workers, a step that could delay surveillance, refurbishments, and deliveries to the Department of Defense.

Southern Ocean’s Carbon Sink
The Southern Ocean, a vital global carbon sink, is defying climate model predictions by maintaining its capacity to absorb CO2, a phenomenon now potentially explained by a study published in Nature Climate Change. Researchers have discovered that an increase in cold, low-salinity surface water has been effectively trapping CO2-rich deep ocean water, temporarily offsetting the anticipated weakening of this critical carbon sink due to climate change. Their analysis revealed that since the 1990s, the density difference, or stratification, between the deep and surface waters has actually strengthened. The near-surface water has become less salty—a process known as “freshening”—due to increased inputs from precipitation and the melting of glaciers and sea ice. While the freshwater barrier has provided a crucial temporary buffer against climate model predictions, the study warns that the situation is becoming increasingly precarious.
This map depicts how Southern Ocean freshening since the 1990s has enhanced density stratification, which prevents deep CO2-enriched waters from reaching the surface. Click on the map to learn more.

Q: What two U.S. states don’t have counties?
A: Alaska and Louisiana
In the U.S., counties are most often the government unit directly below the state level, but can often be only geographical and not political. While Rhode Island and Connecticut have counties, they have no government at the county level. In Louisiana, instead of counties, the state is divided into parishes, and in Alaska, into boroughs. Louisiana is the only state whose political subdivisions are parishes. Its parishes and legal structure date back to its colonial history, when Louisiana was a French colony before being sold to the United States and eventually becoming a state. Due to Alaska’s sparse settlement, the state believed it didn’t have a large enough population to merit county governments, so it opted to use boroughs with the intention of being more versatile than counties. Before the 1980 census, the Alaska census relied on geographic divisions, geographic districts, election districts, and more to parse out the state.
