Helicopter-Plane Crash in DC
Yesterday evening, a 60 passenger, 4 crew-member plane collided with a helicopter carrying 3 U.S soldiers in Washington, DC. There were no survivors. After the collision, the two aircraft fell into the Potomac River. The authorities are currently conducting recovery efforts. As of this morning, 27 bodies from the plane and one from the helicopter have been found. The plane was an American Airlines flight coming from Wichita, Kansas to Washington Reagan National Airport (DCA). The UH-60 Black Hawk helicopter came from Davison Army Airfield in Fort Belvoir, Virginia, and was conducting a training flight. The Federal Aviation Administration (FAA) and the National Transportation Safety Board (NTSB) are investigating the incident.

Sinkhole Rescue Continues
A difficult rescue operation to pull out a 74-year old man from a sinkhole in Yashio entered its third night. The hole first opened up on Tuesday during rush hour, swallowing the man’s truck, and unstable ground around the hole has obstructed rescuers. The sinkhole was caused by the rupture of an underground sewage pipe. Nearby residents have evacuated, and Japanese authorities have asked 1.2 million people to reduce their water usage to prevent leaking sewage from expanding the hole. The sinkhole is now 65 feet (20 m) wide.

Rapid Ocean Surface Warming
An overview of the world’s ocean surface temperature readings from 2023 and early 2024 published in Environmental Research Letters shows the temperature is increasing at a rate 400% faster than the oceans were warming during the 1980s. While an El Niño weather pattern was partly responsible for this rise, researchers believe that roughly 44% of the warming was due to unexpected heat absorbtion by the oceans unconnected to El Niño. While increasing levels of human-produced carbon dioxide in the atmosphere are a factor, other potential contributors include an increase of water vapor in the atmosphere from the eruption of Hunga Tonga-Hunga Ha’apai in 2022, a decrease in aerosols from shipping that reflect away heat back into space since 2020, and a peak in the solar cycle. Through the observation period of 2023 into 2024, average ocean heat temperatures broke records for 450 consecutive days.
This map depicts anomalies in ocean surface temperature readings from January 27, 2025. Recent research shows that ocean surface temperature readings are accelerating faster. Click on the map to learn more.

Q: How many modern-day countries are within the greatest extent of the Inca Empire?
A: Six
The Inca Empire, officially known as the Realm of the Four Parts, was the largest empire in pre-Columbian America. At its largest, the Inca Empire spanned modern-day Peru, western Ecuador, western and south-central Bolivia, northwest Argentina, the southwesternmost tip of Colombia, and a large portion of modern-day Chile. The administrative, political, and military center of the empire was in the city of Cusco, Peru. The Inca civilization rose from the Peruvian highlands sometime in the early 13th century. The Spanish began the conquest of the Inca Empire in 1532, and by 1572 the last Inca state was fully conquered.
