The silent tug-of-war between the clock and the sun in Europe

In Europe, time zones are meant to align daily life with the sun’s rhythm, but in reality, many countries run on a social clock that’s out of sync with their geographical position. A new map shows exactly how well (or badly) nations match their time zones to their natural solar time: some tick in near-perfect alignment (marked in dark green), while others live in what feels like a parallel timeline (shaded brown).

Did you know that 70% of people are right-eye dominant, while roughly 30% are left-eye dominant? That’s according to visual science sources citing ocular dominance studies.

Abortions laws around the world

Across the globe, the ability to end a pregnancy still depends largely on where you live. The map above captures the patchwork of how some countries allow abortion on request (often with gestational limits), others restrict it to narrow grounds such as risk to the patient’s life or health, rape, or fetal impairment, and a few still prohibit it entirely. The World Health Organisation estimates that about 73 million abortions occur each year, where laws are restrictive, unsafe procedures rise and account for an estimated 4.7–13% of maternal deaths, while deaths from safe, regulated abortion are exceedingly rare.

Twenty-four years later, the September 11, 2001, terrorist attacks remain etched deeply in collective memory around the world.

Which beverages have the most caffeine?

When it comes to your morning to-go or afternoon beverages, not all drinks are created equal. This article ranks popular energy drinks and sodas by the amount of caffeine they pack into a 12‑ounce (350ml) serving. According to the Mathematics Department at the University of Utah, the energy drink Red Bull contains about 80 mg of caffeine in an 8.2‑ounce can. That may not sound like much compared with coffee (a typical 8‑ounce drip coffee ranges from 115 mg to 175mg), but it’s nearly four times the amount in a 12‑ounce can of Coca‑Cola. Another early energy drink, Jolt Cola, packs 71.2 mg of caffeine per 12 ounces, still formidable even decades after its launch.
