ScienceAlert: Natural Compound in Olives May Help Fight Obesity And Type 2 Diabetes
A naturally occurring compound in olives, elenolic acid, has shown promise as a potential treatment for obesity and type 2 diabetes.
In mouse models of the health conditions, researchers from Virginia Tech in the US discovered that after one week of treatment, elenolic acid reduced blood sugar levels as well as, or even better than, two leading medications.

Chemical signals play major roles in orchestrating messages from our gut. In a previous study on mice from Liu’s lab, the team found that elenolic acid prompts the release of two metabolic hormones that help us sense when to stop eating, by signaling fullness to the brain.
One of those hormones is glucagon-like peptide-1 (GLP-1), which Ozempic and similar drugs mimic in order to regulate blood sugars and satiety. The other is the less well-known peptide YY (PYY), which is released by cells in the gut to reign in your appetite at the end of a meal.
AdaFruit: Feather of the Day: Adafruit RP2040 Feather ThinkInk for 24-pin E-Paper Displays
Easy e-paper _and _RP2040 finally come to your Feather with this Adafruit RP2040 Feather Think Ink that’s designed to make it a breeze to add almost any common e-Ink/e-Paper display. Chances are you’ve seen one of those new-fangled ‘e-readers’ like the Kindle or Nook. They have gigantic electronic paper ‘static’ displays – that means the image stays on the display even when power is completely disconnected. The image is also high contrast and very daylight readable. It really does look just like printed paper!
We’ve liked these displays for a long time, and we’ve got Arduino/CircuitPython drivers for tons of the various display chipsets, so wouldn’t an e-paper RP2040 Feather make a ton of sense? Luckily for us, just about every small-medium size eInk display made these days has a standard 24-pin connection. This Feather will add all the power supply support circuitry and level shifting so you can attach your favorite display – we’ve tested it with up to 5.6″ sized 7-color ACeP displays.
CNN: The planet saw its hottest day on record
July 21 clocked in at 17.09 degrees Celsius, or 62.76 Fahrenheit, and was the hottest day on Earth since at least 1940, according to the preliminary data from the European Union’s Copernicus Climate Change Service.

Sunday’s record came as many countries endure prolonged and brutal heat waves. Around a hundred cities across the US are experiencing their hottest start to summer on record, and swaths of southern Europe have been grappling with triple-digit temperatures.
Despite being based on data from the mid-20th century, the temperature records represent the warmest period the planet has seen in at least 100,000 years, scientists have found from many millennia of climate data extracted from ice cores and coral reefs.
UPI: Study shows shift in GLP-1 drug use for obesity, not diabetes
New prescriptions for these drugs have doubled among people who have obesity but not diabetes, investigators found.
As a result, drug shortages have triggered a drop in new prescriptions for Type 2 diabetes, even though Ozempic and Mounjaro were initially developed as diabetes drugs, the researchers said.
Both drugs were later approved for weight loss under different brand names, Wegovy and Zepbound.
