Cocoa Fights the Flu?
In a bacteria-powered drug hunt, researchers at Hebrew University have brewed up a powerful antiviral cocktail that may outpace oseltamivir against influenza. Using clever bacterial assays to mimic the flu’s M2 channel (a viral proton transporter and drug target), the team screened a library of known drugs and landed on a surprising synergy: theobromine (yes, from chocolate) and arainosine (a nucleoside metabolite) block both aminoadamantane-sensitive and -resistant flu strains including H1N1 and H5N1. The duo outperformed oseltamivir in cellulo and mouse models, slashing viral RNA by up to 15,717-fold and weight loss to just 6% compared to untreated controls. Best part? Their resistance profile is minimal thanks to distinct and complementary binding in the M2 channel. So while caffeine might keep you up, this chocolate-inspired combo could keep flu down.

Past Lives, Present Minds
Who remembers a past life? According to a new national survey out of Brazil, mostly middle-aged, highly educated women who identify as Spiritist and spiritual. In this small study of 402 adults reporting past-life memories (PLMs), most said these memories emerged spontaneously—on average around age 20 years—and were often accompanied by striking features like childhood phobias (71%), birthmarks or physical anomalies (54%), or even odd fascinations (30%). While intriguing, PLMs were not all harmless flashbacks: 46% screened positive for common mental disorders, and nearly 36% for PTSD. Childhood phobias and unusual philias were significantly linked to those diagnoses. Still, there was a bright side—those with stronger religious or spiritual beliefs reported greater happiness and fewer mental health symptoms overall. In fact, religiosity and spirituality appeared to be protective, suggesting that worldview may play a role in how people interpret and cope with these experiences. While past-life memories in children have gotten the spotlight, this study points to the need for serious research into the adult experience—and its mental health implications. Because whether or not these lives were lived before, their impact in the here and now is very real.

Microbes Whisper ‘You’re Full’
Your gut isn’t just digesting—it’s detecting! Researchers at Duke University uncovered a “neurobiotic sense,” a gut–brain pathway that lets the colon sense microbial chatter and adjust feeding behavior in real time. The star player? Flagellin, a protein found on bacterial tails, which activates the pattern recognition receptor TLR5 on PYY-labelled neuropod cells in the colon. These cells then release the satiety hormone PYY onto NPY2R-expressing vagal neurons, signaling the brain to put the fork down. Mice lacking TLR5 in these cells ate bigger meals, gained more weight, and didn’t show the usual metabolic or inflammatory issues, proving this was no immune fluke. Even in germ-free mice, a flagellin enema cut food intake within 20 minutes—fast and independent of the microbiome. Blocking TLR5 or the NPY2 receptor erased this appetite-suppressing effect. Nearly 60% of vagal neurons tested responded exclusively to flagellin, not nutrients, revealing a direct microbial-to-neuron line. No inflammation, no infection—just microbes nudging neurons. Looks like the gut has a sixth sense after all.

Apple Snails Crack Eye Code
Move over salamanders—Pomacea canaliculate (P. canaliculate), the apple snail, just stole the spotlight as the first invertebrate with camera-type eyes and a proven ability to fully regenerate them after complete removal. In this tour-de-force study published in Nature Communications, researchers showed that these snails not only rebuild complex eye structures within 28 days, but also express conserved vertebrate eye genes like pax6 throughout regeneration. Even more impressive? They created the first CRISPR-ed pax6 knockout in a lophotrochozoan, and the snails completely lost their eyes—confirming pax6 is essential for eye development, just like in humans. Using electron microscopy, transcriptomics, and a newly developed ex ovo embryo culture system, the team mapped out the entire regeneration process, from blastema formation to retinal layering and lens reformation. The snail’s eye anatomy blends vertebrate and invertebrate traits, with rhabdomeric photoreceptors and shared gene regulatory networks, making it a living bridge between evolutionary lineages. With stable gene editing now in play, P. canaliculata emerges as a genetically tractable model for studying organ regeneration and the evolution of vision—one tiny, gooey eye at a time.

Treadmills, Tea & T-Cells
In a playful twist on cancer care, a recently published review makes the case for green tea and exercise as immunological sidekicks in oncology. While past studies have praised their benefits, few have zoomed in on how they boost immunity—until now. Regular physical activity may help reactivate tired T cells and ramp up natural killer cell function, while green tea’s star compound, epigallocatechin gallate, could promote anti-inflammatory cytokine release and enhance CD4⁺ and CD8⁺ T-cell responses. Moderate-intensity exercise showed the most promise, with high-intensity potentially doing more harm than good. And though the authors got the ball rolling, the review fills the gap by emphasizing that both green tea and exercise modulate immune function at multiple levels—including through changes in the gut microbiome and T-cell mitochondria. They called for future studies to dissect these mechanisms at different cancer stages, especially as immunotherapy becomes mainstream. Bottom line? Green tea and a jog may not replace treatment—but they just might help supercharge the immune system along the way.
