Journal Club: Newfound avenue for disrupting peroxisome organelles could have big implications in the cell
Peroxisomes are packages of enzymes that help destroy toxins and digest fuels for cells. Disrupt the assembly of these organelles, and the results could be fatal for humans. Previously, all mutant proteins linked to such disorders were thought to be … Continue reading

Journal Club: Fruit flies use a protective reflex to kick mites off their wings
Predatory mites are only 200 to 300 micrometers long, but to 3 millimeter-long fruit flies, these tiny arachnids pose as much of a threat as a rat-sized blood-sucking tick would to a human. Now scientists find that fruit flies have … Continue reading

Journal Club: How social structure might drive the evolution of cumulative culture
Humans accumulate knowledge over generations, building vast bodies of expertise—a quality that scientists have long suggested helps make humanity unique. In order to explore how such “cumulative culture” arose, anthropologists examined the way in which hunter-gatherers known as the BaYaka … Continue reading

Journal Club: Rats can be trained to “taste” light, sound, touch, and smell
Imagine the sight, sound, smell, taste, and feeling of peeling and eating an orange. Scientists had long thought the brain handled such multisensory experiences via brain regions known as primary sensory cortices that are exclusively unimodal—that is, each devoted solely … Continue reading
