The chemical synthesis and anti-cancer properties of portimines
Nature, Published online: 20 September 2023; doi:10.1038/d41586-023-02788-yThe natural toxins portimine A and B have attracted interest for their unusual chemical architecture and potent anti-cancer activity. The first total synthesis of portimines enables the identification of portimine A’s molecular target and reveals that the toxin induces programmed cell death in human cancer cells.

Controlling emission energy in metal & #x2013;organic frameworks featuring cyclometalated iridium(III) linkers
Carol Hua, Timothy U. Connell Diagram of iridium and metalloligands combining with Ca2+; graph of resulting metal–organic framework luminescence peakThree iridium(III) metalloligands containing different cyclometallating ligands were incorporated into Ca2+ metal–organic frameworks yielding luminescent materials. Changing the cyclometalling ligand altered the emission wavelength, highlighting the utility of this approach for the generation of tailored solid-state materials for applications including chemical sensing.

Cycle Syncing Won ’ t Fix Women ’ s Fitness
While most of the video series and programs available on the popular “holistic wellness”/fitness site Alo Moves—owned by the trendy activewear line Alo Yoga—are run by solitary instructors, the company’s newest offering is marked by photos and videos of a group of four women pulled close up against one another and roaming Hawaiian beaches.
It’s a clearly symbolic presentation of the company’s new SYNCD program, a collection of 24 videos designed to guide users through self-care and fitness activities customized for each of the four phases of the menstrual cycle. The program, whi...

60% Of Sun Screens Would Fail Federal Safety Tests!
Here in South Florida, spring break is in full swing.
Temperatures are in the mid-to-high-80s, and tourists are flocking to our beautiful, sunny beaches.
Of course, that also means it’s prime time for sunscreen companies to kick up their marketing efforts in an attempt to whip up more fear over the sun.
They want to scare you into thinking that each time the sun strikes your unprotected skin, you risk malignant melanoma, the deadliest form of skin cancer.
If you’re a regular reader, you know that I’ve been vocal about Big Retail’s money grab and how they put out misinformation because they profit each time you slat...

How To Avoid China ’ s Medicine Monopoly
I want to share a shocking statistic with you…
Around 80% of all the pharmaceuticals sold in America — both prescription and over-the-counter — are manufactured in China.
I’m talking about drugs for Parkinson’s and Alzheimer’s, blood pressure and blood thinners, diuretics, aspirin, antibiotics, and a big chunk of the world’s insulin and diabetes drugs — just to name a few.1
We don’t even make penicillin anymore. The last penicillin plant in the U.S. closed its doors in 2004.
Americans who rely on medicine are now almost entirely at the mercy of a country whose relations with the U.S. have become more ...

Why Diabetes Risk Is Higher For Older White Women
Phthalates – the toxic chemical cocktail manufacturers use to make plastic products more durable and personal products smell better – can increase your risk of developing diabetes by up to 63%…
That’s the terrifying conclusion of a new study published in the Journal of Clinical Endocrinology & Metabolism.1
And according to the researchers, the damaging effects extend beyond diabetes in these women.
Phthalate exposure also contributed to a higher incidence of obesity, infertility, and other endocrine disorders over a six-year period.
For reasons not yet understood by the scientists, this damaging associatio...
