A gigantic solar eruption in November 2021 defied expectations. Two spacecraft—Solar Orbiter at 0.85 AU and Wind at 0.98 AU—watched the same coronal mass ejection (CME) as it zoomed through the solar wind. Normally, a CME plowing into slower wind should slow down, like a boat hitting chop, but this one sped up. It was a genuine space weather mystery. In their paper published in The Astrophysical Journal Letters, the researchers report that only an unseen internal "engine" could explain the anomaly.

A tiny, iridescent shell seal found in an ancient garbage pit in Israel is the first of its kind ever found in the region and may have belonged to a community deported and relocated by one of the ancient world's mightiest empires thousands of years ago.

Hidden beneath the scorched expanse of the central Libyan Sahara lies a prehistoric graveyard that was once a lush, green gateway to a continent. For decades, the origin of Africa's higher primates has been one of evolution's most enduring mysteries, centered on a single, pivotal question: How did the ancestors of monkeys and apes first cross ancient oceans to reach their new home? Now, a handful of microscopic fossils recovered from these silent sands is threatening to overturn the traditional timeline of that epic journey.

Think of an athlete eyeing the finish line—could a single shot of caffeine be the difference between a podium finish and a personal best? For decades, runners and cyclists have treated the stimulant as a near-magical performance aid, yet the "perfect" dose has remained a subject of locker-room legend and conflicting advice. While some athletes swear by a morning espresso, others push the limits with high-dose supplements, chasing a faster sprint at any cost.

AI chatbots like ChatGPT have made their way into college life, sparking an important debate: Do these tools actually help students become better thinkers, or are they just a shortcut? Universities want to foster critical thinking, creativity and problem-solving, which makes it essential to explore how AI influences these areas.

Imagine a world the size of Neptune, but instead of following the orderly path of its neighbors, it is racing headlong against the flow of its own solar system. In the case of the exoplanet TOI-1710 b, the cosmic clockwork has gone topsy-turvy. This "warm Neptune" doesn't just have a slight tilt; it appears to be performing a backward dance around its sun—an extreme orbital misalignment that hints at a violent, tumultuous history.

For women with polycystic ovary syndrome (PCOS), the journey to fertility can be difficult. But what if a simple, natural supplement could provide a big boost? This hopeful question has focused attention on myo-inositol, a nutrient already popular with many women with PCOS.

From ancient graves to stories of survival on the frontier, signs of human flesh-eating turn stomachs, even as they raise questions. Anthropologists have uncovered bones cut up with axes and chops—like a skull from England dating back 14,700 years that had the meat scraped off its jaws. Such finds confirm that our ancestors sometimes ate each other, but now every human culture views cannibalism as a final taboo. But if eating kin saved lives, why didn't it become routine?

Deep in the Atlantic Ocean, the Lost City hydrothermal field is known for eerie white chimney structures made of carbonate. Alkaline hot springs, loaded with hydrogen and methane, emerge from the seafloor there. Rather than depending on sunlight for survival, living organisms thrive on energy produced by the reaction of water with rocks underground. However, one question remained: Where does the energy-rich fluid that feeds this strange ecosystem actually come from?

It was in the year 2022 when students and working individuals began making use of generative AI tools such as ChatGPT for writing their essays or solving problems. The convenience of obtaining coherent text or some other solution instantly is almost magical. While this technology is certainly useful, it raises a broader issue: what will happen to our thinking? If AI does all the thinking, what will happen to our brains?
