A teenager started hearing a strange pulsing noise, but her mild symptoms were signs of an alarming condition

When Lizzie Clark was 13, she started experiencing a strange ringing in her left ear. At first, she thought the tinnitus-like sound was a side effect from a cold. But the cold left, and the sound lingered, pulsing in time with her heartbeat.
For months, the "strange pulsing noise" was constant, Clark told CBS News. Her parents took her to see her primary care physician, then an ear, nose and throat doctor, but it wasn't until she underwent a CT scan that doctors finally found the cause. The eighth-grader was racing in a track meet when doctors called her parents and said they had seen a growth behind her eardrum.
"I was terrified. I was 13. I was like, 'What growth? What does that mean?'" Clark recalled. "There were a lot of questions buzzing around."
It's unusual for a new social media service to get a foothold in a marketplace entrenched by the likes of X (formerly Twitter), Instagram and TikTok which, dominate people's phones. But Bluesky, a nearly 2-year-old app, is now grabbing attention amid a recent surge of new users, which the company says is likely due to growing frustrations with X.
As NASA scientist Chad Greene flew over northern Greenland with a team of engineers in April, they never expected their radar to find something manmade buried deep within the ice. Greene and his team were flying above the Greenland Ice Sheet on a NASA Gulfstream III plane, scanning the barren expanse of ice that's more than a mile deep in some areas, when their radar instrument picked up something unusual.
