Researchers Prevent Inheritance of Faulty Mitochondria in Monkeys

Sam Kean

<jats:p>Shoukhrat Mitalipov and colleagues at the Oregon Health and Science University near Portland have achieved a technical feat in monkey cells that could lead to new methods for preventing the inheritance of mitochondrial diseases.</jats:p>

Palabras clave: Multidisciplinary.

Going to the Dogs

Virginia Morell

<jats:p>Cognitive scientists once spurned the dog as too domesticated to study. But now many are leaping at the chance to use man's best friend to help understand how social cognition evolved.</jats:p>

The Large Hadron Collider Redux: Hoping for a Long, Hard Slog

Adrian Cho

<jats:p>As they prepare to restart the Large Hadron Collider, accelerator physicists are confident that, instead of suffering a second catastrophic breakdown, the world's largest atom smasher will perform to the standards set by its predecessors—and give them lots of smaller headaches to struggle with.</jats:p>

How to Make a Collider

Adrian Cho

<jats:p>A synchrotron circulates particles in one direction, so it takes some extra work to make one into a collider.</jats:p>

Comment on “Floral Iridescence, Produced by Diffractive Optics, Acts As a Cue for Animal Pollinators”

Nathan I. Morehouse; Ronald L. Rutowski

<jats:p> Whitney <jats:italic>et al</jats:italic> . (Reports, 2 January 2009, p. 130) investigated the mechanism of iridescence in hibiscus and tulip flowers and suggested that bumblebees are able to use this iridescence as a pollination cue. However, their study failed to isolate iridescence from other coincident visual cues, leaving open questions regarding the importance of iridescent stimuli in foraging-based associative learning in bumblebees. </jats:p>

Response to Comment on “Floral Iridescence, Produced by Diffractive Optics, Acts As a Cue for Animal Pollinators”

Heather M. Whitney; Mathias Kolle; Piers Andrew; Lars Chittka; Ullrich Steiner; Beverley J. Glover

<jats:p>Morehouse and Rutowski make interesting comments on the difficulties of untangling complex optical phenomena. However, our use of a four-colored transfer test in our original study, along with spectrophotometric analysis of the nonoverlapping colors produced by our target disks, allows us to conclude that bees can learn to use iridescence as a foraging cue.</jats:p>
