Scientists have created a novel method of contraception, using polymer beads coated in a special protein as “decoy” eggs in mice. In experiments described in Science Translational Medicine, researchers deposited the beads in the uteruses of mice. When the mice mated, sperm cells bound themselves to the fake eggs, preventing the real eggs from being fertilized. The scientists from the National Institutes of Health say it’s extremely unlikely the beads would be used in their current form as human contraception, but that they do show promise as a better way to select sperm for use in fertility treatments.

New Drug Compounds Show Promise Against Endometriosis
Two new drug compounds – one of which has already proven useful in a mouse model of multiple sclerosis – appear to be effective in treating endometriosis, a disorder that, like MS, is driven by estrogen and inflammation, scientists report in Science Translational Medicine.
