Ancient Roman Bigfoot? 'Unusually Large' Shoes Puzzle Archaeologists - ScienceAlert

Two brothers named Gary and Shaggy have helped Cornell University researchers make a rare genetic discovery. In a study published in Scientific Reports, scientists reported the first molecular characterization of Marfan syndrome in domestic cats, a condition primarily recognized in humans. Gary and Shaggy first stood out as kittens because of their unusually long limbs. As they grew older, veterinarians also identified abnormalities in their eye structures and an enlarged aorta, the body's main artery. Together, these symptoms suggested Marfan syndrome, an inherited condition that weakens connective tissues throughout the body. The disorder affects approximately 1 in 4,000 people, but these brothers represented the first known documented feline cases.

The straight tusks of narwhals, which are mainly found on males, are an oddity among living animal species. This pod is swimming in oceans around northwest Greenland. (Carsten Egevang)The narwhal tusk is a true oddity in the natural world. Reaching up to three metres in length, the tusk is an upper tooth that grows through the whale's lip on the left side. And it is the only mammal tusk that grows perfectly straight, with no curves. A team of international researchers believe they have figured out why it grows so straight — and the answer lies in its unique pattern of opposing spirals.

For more than 150 years, a reported 16-minute train delay in Exeter, England, was cited as a possible early example of a solar storm disrupting human technology. But a railway timetable revealed a problem with the story: the railway line in question did not exist in 1841. According to a report published by ScienceDaily on October 21, 2026, researchers have now traced the incident to October 18, 1848, using historical railway records, newspaper accounts and measurements of Earth’s magnetic field. The findings were published in the journal Space Weather. The train delay that could not have happened in 1841The mystery originated in an account published anonymously in the scientific journal Nature on October 5, 1871. It described a “very intense magnetic disturbance” on October 18, 1841, which allegedly interfered with railway telegraph equipment in Exeter, a city in southwest England. According to the account, the disturbance prevented railway staff from establishing whether the track ahead, near the village of Starcross, was clear. As a result, the scheduled 10.05 pm express train from Exeter towards Newton Abbot was held up for 16 minutes.
