What were our ancient relatives' relationships like? Dozens of genetic studies have shown that Neanderthals and modern humans interbred over tens of thousands of years and across multiple continents — making the genome of nearly every person outside Africa today roughly 2% Neanderthal. Yet not a single archaeological site has shown them living together. So how did it happen? And why? The answers are written on the human X chromosome, and they're stranger than expected.

See what's new on Pro Beyond the headlines Christina Applegate misdiagnosis: Why can MS be difficult to diagnose? Actor Christina Applegate was diagnosed with multiple sclerosis (MS) over five years ago — but this week, she announced that a recent reevaluation found that she doesn't have the condition after all. In the wake of that revelation, she's been left without a diagnosis, and she said on a podcast that she felt she was "back at square one, where I don't know what's going on with me." Applegate's case is not totally unique, although MS diagnosis has improved over the years. Studies offer different estimates of how frequently MS is misdiagnosed, with rates ranging from 5% to over 40%, depending on the patient population and clinical setting. There is also some degree of underdiagnosis — cases in which people with MS aren't flagged as having the disease. So, how difficult is MS to identify, and what does that mean for patients? Live Science spoke with experts about the current state of MS diagnostics and the improvements that may be coming in the future.

The surprise snap reveals that the top-secret vehicle is very similar to its American counterpart and provides new clues about its capabilities.   The image is widely believed to show China's secretive Shenlong, or "divine dragon," space plane, which has been in action for just over six years. During this time, the reusable winged spacecraft has repeatedly made headlines after deploying various unidentified objects in low Earth orbit. As a result, government officials, private companies and individual researchers have closely monitored the vehicle using tools such as ground-based radar.   Until now, the only direct images of the space plane have been blurry snaps of light reflecting off the uncrewed vehicle toward Earth's surface — offering no clear clues to its specific design, capabilities or intended purpose. China has also never publicly shared any photos of the vehicle or revealed any key information about its design.
