Unbelievable facts

A female red kangaroo can support three generations at once: an older joey outside the pouch that still drinks milk, a younger joey inside the pouch, and a paused embryo waiting inside her uterus.

It took nearly two years to confirm the father because Momo was very protective of her baby, making sample collection difficult. The baby, born on February 10, 2021, was a healthy male whose parents belonged to two different gibbon species.

The reusable patch weighs only about 7.2 grams and measures roughly 3 centimetres across. It can detect throat movements without vocal-cord vibration, meaning users can silently move their speaking muscles while the system produces the matching recorded phrase.

Unlike many back-support exoskeletons, this suit has no hard metal frame. Its soft fabric design bends naturally with the wearer, while a knitted sensor uses changes in fluid pressure to detect back movement and automatically activate the artificial muscles.

Sokolof’s ads included bold headlines directly telling McDonald’s that its burgers contained too much fat and its fries were still cooked in beef tallow. Burger King, Wendy’s and McDonald’s all announced changes to their frying oils during the campaign in 1990.

Seoul reported around 59,000 visits from April to December 2025. The city is now expanding the program from four locations to 25 branches by the end of 2026.

GoodGym volunteers can also make regular social visits to isolated older people. The organisation calls these residents “coaches” because they give members a reason and motivation to keep exercising.

Samaritans received its first call on 2 November 1953 from St Stephen Walbrook church. The service was initially nicknamed “999 for the suicidal” and offered confidential, non-judgmental listening rather than formal counselling.

Gleanmer can process maps at 88 to 331 frames per second while using under 6 milliwatts. In tests, it achieved over 96% mapping accuracy, and its map of an entire city block needed less than 400 kilobytes of storage.

BMI is only a screening tool, not a complete health diagnosis. It cannot tell the difference between fat and muscle or show where body fat is stored, so doctors may also consider waist size, blood pressure, cholesterol and other health details.

Firm foods like carrots or hard cheese can sometimes be saved by cutting at least 2.5 centimetres around and below the mold. Bread is different because its porous texture lets contamination spread beneath the surface much more easily.

The wrecks were found at very different times. K-129 and USS Scorpion were located in 1968, INS Dakar was found in 1999, and Minerve remained missing until 2019. Together, the four disasters claimed the lives of 318 submariners.

Jeran Campanella, a longtime flat-Earth advocate, publicly admitted he had been wrong to deny the 24-hour Antarctic Sun. Another participant, Austin Whitsitt, accepted the observation but said he still did not think it proved a globe, showing the trip changed some views more than others.

The core reaches across a mysterious period when Earth’s ice-age cycles changed from roughly 41,000-year cycles to 100,000-year cycles. Scientists hope the ancient greenhouse-gas record will help explain why this huge shift happened.

Latvia’s gap is partly linked to life expectancy. Official Latvian statistics say women lived about 80.4 years in 2023, while men lived about 70.4 years, leaving a 9–10 year gap in recent years.

A controlled elliptical study compared machine readings with a metabolic cart, which measures oxygen use. It found one Life Fitness model slightly underestimated calories, while one Precor model overestimated by 24.7%. So the main lesson is simple: don’t “eat back” calories just because the machine says so.

The Gamburtsev Mountains were first discovered in 1958, but no human has actually seen them directly because they are sealed under the ice. The range is often compared to the European Alps because of its size and rugged shape.
