Proceed with Caution
While genomic data sharing is essential for research, scientists must work to keep sensitive, potentially damaging information under wraps.
Avoiding the transmission of mitochondrial disease takes a trio, but raises a host of logistical issues.
Monitoring Magnetic Bugs
Diamonds are a biomagnetologist’s best friend.
In discrete neuron networks linking odor receptors in the nose to higher brain areas, similar odors are parsed by deep-lying cells with narrow odor selectivity.
Ensembles of as few as 25 mushroom body neurons allow Drosophila to distinguish and react to specific odors.
Let It Linger
Prolonged responses to odors, called afterimages, may originate in the brain, rather than in the nose.
An Olfaction Odyssey
Thanks to a book, a war, and a big green caterpillar, John Hildebrand found himself mapping the exquisite and surprising wiring of the insect olfactory system.
