Tomb Fungus, Cancer Hope?
What happens when you mix ancient tomb rumors, toxic fungus, and modern science? You might get a new leukemia-fighting compound. University of Pennsylvania researchers discovered a group of funky little molecules—asperigimycins—hidden inside Aspergillus flavus, a fungus once blamed for “cursed” tomb deaths. After tweaking these fungal ribosomally synthesized and posttranslationally modified peptides, the researchers found that adding a lipid tail helped the compounds sneak into leukemia cells using a gateway gene called SLC46A3. One version packed enough punch to rival U.S. Food and Drug Administration–approved leukemia drugs in lab tests. While the fungus isn’t new, its potential as a source of anticancer compounds could be just getting started.

Global Warming Chokes Sleep
Turns out climate change might be keeping us up at night—literally. In a massive global study, researchers found that hotter days were linked to a 45% jump in obstructive sleep apnea (OSA) risk. Using sleep data from over 116,000 people across 62 million nights, they saw that heat-related sleep issues in 2023 alone may have cost nearly 800,000 healthy life-years and an estimated $98 billion across 29 countries. Productivity took a hit too—105 million workdays were potentially lost thanks to heat-triggered sleep apnea. If the planet keeps warming, OSA burdens could double by 2100. So yeah, it’s not just your AC bill that’s sweating.

Your Brew May Matter in Cancer Risk
We’re talking tea again this week—but coffee’s also crashing the party. Researchers from the INHANCE consortium brewed some intriguing data: in a massive, pooled analysis of over 25,000 people, drinking more than 4 cups of caffeinated coffee a day was linked to a lower risk of head and neck cancers—especially oral cavity (odda ratio [OR] = 0.70) and oropharyngeal cancers (OR = 0.78). Even decaf drinkers got a little love, with less than 1 cup per day tied to reduced oral cancer risk. Tea sippers saw a dip in hypopharyngeal cancer risk, but oddly, drinking more than 1 cup a day was linked to a higher risk of laryngeal cancer (OR = 1.38)—maybe due to reflux. So sip smart—your brew may be doing more than keeping you awake.

Meet P40: The Smart Synthetic Skin
Researchers have created P40, a next-generation electronic “skin” that feels, heals, and might just upgrade your surgical toolkit. This graphene-PEDOT:PSS composite stretches 600%, recovers in 20 seconds, senses everything from pressure and pH to dopamine and hydrogen peroxide, and even regulates heat—perfect for monitoring wounds, muscles, or real-time vitals. The technology sticks to skin, muscle, and even brass; costs under $140/kg; and prints like a dream. Bonus: it helped a robotic snake detect, react, and melt obstacles—imagine that in smart bandages or cyborganic implants.

Can mangos mellow out menopause? Maybe! Researchers had postmenopausal women eat 330 g of mangos daily for 2 weeks and found some subtle but juicy perks. Blood pressure dipped, cholesterol improved, and blood sugar behaved better than it did with white bread. Talk about a sweet swap. Microvascular function didn’t change significantly, and inflammation stayed around the same, though one marker (E-selectin looked like it was thinking about budging. So, the mango didn’t do it all, but it might be flexing some cardiometabolic potential.
