Science news this week: Polar vortices and volcanoes undersea
Jan. 3, 2025: Our weekly roundup of the latest science in the news, as well as a few fascinating articles to keep you entertained over the weekend.
It's a chilly start to 2025 for many as an expanding polar vortex is expected to bring dangerously low temperatures to the eastern half of the U.S. While it's too early for precise measurements, forecasters predict that this month could be the coldest January in the U.S. for more than a decade.
But weather forecasts are not the only 2025 predictions in this week's science news…
West Coast volcano about to blow
Undersea volcano off Oregon coast could erupt this year, geologists predict
Axial is an underwater volcano located 300 miles (480 kilometers) west of Cannon Beach, Oregon. The seamount erupts fairly regularly and is relatively close to the shore, making it a perfect site for studying volcanic activity.
Predicting when a volcano is going to erupt is a difficult feat — and one that usually can only be done a couple of days in advance. However, volcanologists hope that by studying Axial, they may be able to gain new insights into how a volcano's surface activity reflects the movement of magma and fluids underneath, which could help them improve longer-term eruption forecasting.

Could we ever retrieve memories from a dead person's brain?
Neuroscience has advanced exponentially in recent decades, and we now have a pretty good idea of the physical locations where memories are stored in the brain. But could we ever isolate specific memories and program them into machine learning algorithms to replay those special moments?
Legendary ancient battleground uncovered
Lost site of Alexander the Great's famous battle against ancient Persians discovered in Turkey
The Battle of the Granicus in 334 B.C. was one of the most significant turning points in the rise of the famous Macedonian king, Alexander the Great. However, the site of the battlefield has been somewhat of a mystery — until now.
Archaeologists have been sniffing around the area in northwest Turkey since the 19th century, and human skeletons and weapons have been found at the site. However, thanks to modern techniques, researchers have reconstructed what the area might have looked like in Alexander's time, to further support theories of the battleground's location and rule out other contenders.

Earth from space: 'Lake of clouds' appears between volcanic nesting dolls in Russia via rare mirror-like phenomenon
There's something magical about seeing Earth from an airplane window — even more so if you're an astronaut on the International Space Station (ISS). And sometimes, Earth can treat us to impressive optical illusions that can only be seen from above.
In this image, an astronaut has captured one of Russia's deepest lakes — Kol'tsevoye Lake — sandwiched between two halves of a volcano as its surface transformed into a reflective sea of swirling clouds. The illusion occurred thanks to a rare mirror-like phenomenon, known as "sunglint," which relies on sunlight bouncing off a watery surface at an angle.
