How ‘Lipid Rafts’ Help Us Mount an Immune Response
Lewis Carroll might have dreamed up the ‘lipid rafts’ that float around inside our cell membranes. Yet far from featuring as a subplot in Through the Looking Glass, these tiny fat-enriched platforms appear to ramp up the sensitivity of certain immune cells, helping us mount an immune...

Built-in Amps: Scientists Explore How Subtle Head Motions, Quiet Sounds are Reported to the Brain
MBL, WOODS HOLE, MA—The phrase “perk up your ears” made more sense last year after scientists discovered how the quietest sounds are amplified in the cochlea before being transmitted to the brain. When a sound is barely audible, extremely sensitive inner-ear “hair cells”—which are...
