What makes cats ginger cats ginger?
What exactly makes ginger cats ginger has been a long standing mystery for scientists. Whilst it has been known for decades that it is down to genetics, it hasn't been discovered where in the genetic code this distinctive colour comes from until now.Two teams of scientists at Kyushu University in Japan and Stanford University in the US have now revealed the mystery. It is all to do with the catchily-named ARHGAP36 gene.Research has found that cats with orange colouring have a section of DNA code missing within this gene.
Why are most ginger cats male?
Not only does this section of missing DNA code explain the cats colouring, but it also explains why many ginger cats are male. The gene with the missing code is carried on something called the X chromosome. Chromosomes are larger sections of DNA. In male cats there is both an X and a Y chromosome, meanwhile in female cats there are two Y chromosomes.This means for a female the missing part of DNA must be present in both X chromosomes for a cat to be fully ginger, whilst in male cats it only has to be present in the one X chromosome. Because of this mixed colouring, such as ginger patches, are more likely in the females.

Mysterious 'UFO' caught hovering over Disney World before vanishing into the darkness: 'It's aliens'
Visitors at Disney World's Epcot got an unexpected sight recently when a glowing orb appeared over the amusement park. Morgan Huelsman, digital director of The Bobby Bones Show and a Tennessee resident, told the radio show that she and her boyfriend were sitting on a patio waiting for the fireworks when a very bright light suddenly appeared. After searching online and finding no information about drones or satellites in the area, Huelsman described the object as a ' UFO,' adding, 'definitely a UFO with aliens.' The video she captured quickly spread online, sparking speculation from social media users. One user noted that a rocket launch from nearby Cape Canaveral had occurred earlier in the week, suggesting it could explain the sighting. The Bobby Bones Show's X account also commented, emphasizing, 'It was never moving.' The clip shows a bright light hovering over Huelsman's head in the black night sky. However, it is unclear whether the object was moving, as the video was not shot steadily, and the date of the recording is unknown. SpaceX did launch a batch of Starlink satellites from Cape Canaveral on August 18, about 60 miles from Disney World. The park has long been a hotspot for UFO reports, likely due to its proximity to NASA's launch sites. This is not the first unusual sighting in Epcot. In December 2024, visitors reported a glowing red orb in the sky. A Falcon 9 rocket launch that night at 7:52pm ET coincided with the sightings, and the reusable first-stage booster reportedly returned to Earth about 8.5 minutes later, landing on the drone ship A Shortfall of Gravitas in the Atlantic. Another Disney patron, who goes by Armand Luigi, Esq. on social media, reported seeing a similar red streak across the sky on December 23, 2024, which he later identified as a SpaceX launch. Despite the plausible explanation, many remain unconvinced. Some social media users suggested the video could be doctored, claiming, 'It's called CGI.' Others continued to speculate about UFOs and extraterrestrial activity. Experts note that Florida's combination of clear skies, frequent rocket launches, and highly populated tourist areas makes it a prime location for misidentified aerial phenomena. . @webgirlmorgan saw this hovering over EPCOT at Disney World for several minutes before it just blipped away. She thinks it's a UFO after doing research to find it's not a drone or a satellite, what do you think it is? — Bobby Bones Show (@bobbybonesshow) August 21, 2025 Amateur astronomers and UFO enthusiasts often record similar events, fueling online discussions and debates about their origin. Disney officials have not commented directly on the sightings, but the park has long embraced curiosity about unusual occurrences, often encouraging guests to share their experiences on social media. Whether the glowing orb was a SpaceX rocket, a satellite, or something else entirely, the video has captured the imagination of park visitors and the public alike. The incident is the latest in a series of unexplained aerial phenomena reported over Florida theme parks, highlighting both the popularity of UFO lore and the visibility of space activity in the region.

Why 'baby brain' isn't what we think
'Baby brain' is often referenced jokingly and dismissively when discussing pregnancy and forgetfulness. But a new brain scan study reveals something more profound: pregnancy does not weaken the brain, it rewires it. Neelam Tailor explores what this means for neuroscience and caregiving, and how little we still understand about women's health

Millions of people threatened by wildfires near their homes, research finds
Why you can trust Sky News The number of people whose lives or property are at risk from wildfires has surged by almost 40% in just two decades, according to new research. Analysis by an international team of scientists showed that 440 million people were threatened by fire encroaching on their homes between 2002 and 2021. And while the area affected decreased over the study period, the number of people affected each year rose by 7.7 million. Dr Matthew Jones, from the University of East Anglia, told Sky News that a combination of climate change and population movements is driving the increase. "We're seeing hotter, drier conditions, and that's leading to more fire-prone weather," he said. "We're also seeing people migrating more and more into areas that are historically fire-prone. In the western US, we see this idyllic, romantic image of living closer to nature. "And that's a trend which is putting people closer to fire-prone landscapes than in the past." The researchers analysed 18.6 million records of wildfires over 20 years. High-profile disasters in the US, Europe and Australia grab public attention, but they only account for 2.5% of the global burned area, according to results published in the journal Science. The vast majority of affected land - 85% - is in Africa. But that is falling as more savannah scrub and grassland is taken over by agriculture - a change so significant that it shows up in global totals, with a 26% fall in land burned over the study period. "The apparent increase in damaging and destructive wildfire impacts on society has until now seemed perplexing because the area burned by fires globally has been falling," said Dr Jones. He added: "By closely analysing the shifting geography of both fire and population, this study brings vital clarity - our work shows that wildfires really are becoming more frequent and intense in populated areas. "These changes bring danger to life, damage to property, and threat to livelihood." The researchers say the increasing vulnerability of human populations to wildfire underlines the urgent need for proactive measures to protect communities. That could include deliberately starting small, controlled fires to burn off vegetation, so it doesn't build up.
