A biotech lost half its value over 0.9%. Yes, zero-point-nine.

Wave Life Sciences posted a 14% drop in visceral fat and actually preserved muscle mass. Investors rewarded them by torching 50% of the company's market cap in a single session. Meanwhile, scientists in China made cancer-killing eye drops from pig semen, and somehow that's not even the wildest story today.

Wave's Obesity Drug Killed Visceral Fat but Barely Moved the Scale. The Stock Paid the Price.

Wave Life Sciences shares cratered roughly 50% in a single day after its obesity candidate WVE-007 showed just 0.9% body weight loss at the 400 mg dose over three months. The cruel irony: the drug actually produced a 14% reduction in visceral fat and a 2% gain in lean muscle, the opposite of what GLP-1 drugs typically do. But in a market where Wegovy delivers 15%+ weight loss and Lilly's retatrutide has hit 28.7%, anything under the FDA's 5% threshold reads like a death sentence.

Why it matters: The obesity drug race has become a one-metric contest: the number on the scale. Until the field evolves to value body composition alongside raw weight loss, biotechs with differentiated approaches will keep getting punished by a market that only speaks GLP-1.

Cancer-Killing Eye Drops Made From Pig Semen Actually Worked in Mice

No FDA-approved eye drop exists for any type of eye cancer, which makes this study in Science Advances worth paying attention to despite the bizarre sourcing. A Chinese research team extracted exosomes (tiny lipid-coated delivery vehicles) from boar semen, loaded them with cancer-fighting nanoparticles, and used them as eye drops that killed retinoblastoma cells in mice while preserving healthy retinal tissue. The logic: sperm exosomes evolved to cross biological barriers, and the eye has plenty of those.
