Time Travel: Science Fiction or Science Fact? Could we one day build a real time machine, race back to ancient times, or even visit our great-great-grandchildren? To answer that, we first need to understand how time works—a question physicists are nowhere near settling. Still, there’s one thing we can state with confidence: traveling to the future is achievable, while going back is either wildly difficult, or simply impossible.

The Skaun hoard (T27224/1 and T27224/2), made up of "payment gold" dated to around A. D. 200–550.

It had been buried in the dirt for around 1,800 years and consisted of around 396 grams (14 ounces) of gold rings. The detectorist handed in his finds to a museum and received the largest finder's fee ever paid out in Norwegian history. He had been rewarded for the gold weight, not its rarity.

The dwarf reed snake curls its body into a loop and cartwheels at high speed to escape predators, a discovery that sheds more light on unusual animal locomotion. Rolling motion is rare in animals mainly because it requires precisely coordinated movements, crucially with the head and most of the sensory organs remaining stable. This is more challenging to achieve at speed, making rapid and controlled rolling inherently difficult. Researchers first documented the unusual cartwheeling motion of the reed snake in a study in 2023, but couldn't explain exactly how it achieved this feat. Now, using high-speed cameras, they discovered that the snake was able to keep its head stable while rapidly rotating much of its body rapidly. This shows how animals may sometimes perform innovative movements that are difficult to predict from their body shape alone, researchers say. Dwarf reed snake (Yosuke Kojima)In the latest study, researchers recorded dwarf reed snakes, which are native to Southeast Asia, from multiple angles and analysed their movements in detail.

DOI: 10.5194/os-22-2471-2026 For years, pilots have observed strong and unusual currents in the 2.4-kilometer-long (1.5-mile-long), 300-meter-wide (984-foot-wide) canal connecting Lake Varna with the Black Sea. Maarja Kruusmaa, an academician and professor at Tallinn University of Technology, and researcher Laura Piho, working with the Port of Varna, undertook detailed measurements to determine the causes of the phenomenon.
