---THIS WEEK'S HIGHLIGHTS:

--Physical Sciences
-Single-ion quantum lock-in amplifier
The 'lock-in' technique is a valuable tool in experimental physics,
used to increase measurement sensitivity while reducing
susceptibility to noise. Now a quantum analogue has been developed,
with the potential to enhance the sensitivity of any quantum sensor.

--Biological Sciences
-Evolved structure of language shows lineage-specific trends in
word-order universals
Analysis of word-order variation in over a third of the world's 7,000
surviving languages suggests that cultural evolution, rather than
either of the two previous theories put forward by Noam Chomsky and
Joseph Greenberg, can explain most aspects of linguistic structure.

--Biological Sciences
-Body plan innovation in treehoppers through the evolution of an
extra wing-like appendage
The bizarre and varied 'helmet' structure sported by the cicada-like
insects known as treehoppers turns out to be -- in evolutionary terms
-- virtually a third pair of wings. The discovery of this previously
unknown variation of the blueprint for insects illustrates how a
structure relieved of its original role is free to evolve in novel
directions.

--Podcast & Video
-This week, companies race into space, treehopper insects help to
explain evolutionary novelty, and the workings of the hummingbird's
tongue.

** Materials chemistry: Catalytic accordions
Nicolas Giuseppone and Jean-Francois Lutz
Single chains of a specially designed polymer fold up in water to form
an encapsulated catalytic chamber. This supramolecular assembly
strategy mimics the one used by enzymes in nature.

** From isotopes to the stars
Creating more exotic isotopes will reveal the stellar formation of
atoms -- a fitting tribute to Ernest Rutherford,
say Michael Thoennessen and Bradley Sherrill.

** Metrology: Filtering noise with a quantum probe
John J. Bollinger
In the science of measurement, increasing the sensitivity to the
quantity being measured while minimizing the susceptibility to noise
is a challenge. A technique demonstrated with a single electron spin
may help to tackle it.
