Things To Do In SW Florida

Smartwatches and rings that claim to measure blood sugar levels for medical purposes without piercing the skin could be dangerous and should be avoided, the U.S. Food and Drug Administration warned Wednesday.

The caution applies to any watch or ring, regardless of brand, that claims to measure blood glucose levels in a noninvasive way, the agency said. The FDA said it has not authorized any such device.

The agency’s notice doesn’t apply to smartwatch apps linked to sensors, such as continuous glucose monitoring systems that measure blood sugar directly.

Roughly 37 million Americans have diabetes. People with the disease aren’t able to effectively regulate their blood sugar because their bodies either don’t make enough of the hormone insulin or they have become resistant to insulin.

To manage the condition, they must regularly check their blood sugar levels with a finger prick blood test or with a sensor that places needles just under the skin to monitor glucose levels continuously. read more

A commercial company’s lunar lander that launched from Kennedy Space Center last week has made a successful entry into the moon’s orbit on Wednesday ahead of its Thursday attempt to stick the landing.

Houston-based Intuitive Machines posted on social media that its Nova-C lander named Odysseus, which blasted off from KSC on Feb. 15 atop a SpaceX Falcon 9, had performed a 408-second main engine burn that put it into a successful lunar orbit of an altitude of about 57 miles.

“Odysseus is now closer to the moon than the end-to-end distance driving across Space City, Houston, TX,” the company posted on X noting it had already traveled more than 620,000 miles in the last seven days.

Odysseus completed its scheduled 408-second main engine lunar orbit insertion burn and is currently in a 92 km circular lunar orbit. Initial data indicates the 800 m/s burn was completed within 2 m/s accuracy. 1/4 (21FEB2024 0920 CST) pic.twitter.com/ZoFStQD3cX
