---THIS WEEK'S HIGHLIGHTS:

--Biological Sciences
-Transitional mammalian middle ear from a new Cretaceous Jehol eutriconodont
The transformation between the reptiles' multi-boned lower jaw and the
single-boned variant in mammals is an iconic example of evolutionary change.
Direct evidence of the transition is scarce, but receives a boost with the
discovery of a fossil mammal from China in which lower-jaw elements are
part-way to middle-ear ossicles but still joined to the lower jaw by a
sliver of cartilage.

--Physical Sciences
-Magneto-thermal convection in solar prominences
Optical and extreme-ultraviolet data from the Hinode satellite and the
NASA Solar Dynamics Observatory show that dark, low-density bubbles
recently discovered in solar prominences gain their buoyancy in the outer
atmosphere of the Sun from a previously unrecognized form of
magneto-thermal convection.

--Biological Sciences
-Loss-of-function mutations in sodium channel Nav1.7 cause anosmia
Humans and mice carrying mutations in the gene coding for the
voltage-gated sodium ion channel Nav1.7, previously shown to be
insensitive to pain, are now found to be unable to perceive odours.

Limited by an outdated PCR system?

If you want to run 15 minute PCR protocols and use 50% less consumables,
choose Piko Thermal Cyclers, Phusion PCR reagents and UTW reaction
vessels. That is everything you need for the most accurate and rapid
PCR results. Update your PCR with the Thermo Scientific PCR portfolio.

EDITORIALS
** A little knowledge
The Japanese authorities have done well in releasing copious amounts
of crude data on the nuclear crisis. But it is imperative for the
data to be provided in more meaningful and user-friendly ways.
http://links.ealert.nature.com/ctt?kn=96&m=36499055&r=MjA1NzcwMjE4MQS2&b=2&j=OTkwNjI4ODcS1&mt=1&rt=0

** This is not a drill
Worst-case scenarios happen. We must prepare for them and be able to
respond.
http://links.ealert.nature.com/ctt?kn=104&m=36499055&r=MjA1NzcwMjE4MQS2&b=2&j=OTkwNjI4ODcS1&mt=1&rt=0

** Universal truths
Rejection of broad commonality in structure of languages has
implications for all sciences.

WORLD VIEW
** Governments must pay for clean-energy innovation
The current obsession with nuclear power is a red herring,
says Marty Hoffert. The United States and others should instead
invest in a clean-energy revolution.

FEATURES
** Oil spill: Deep wounds
The Gulf of Mexico oil spill set records for its size and depth. A year

A fossil from the Early Cretaceous provides insight into the evolution

D. Grahame Hardie
Maintaining an optimal cellular energy status requires sensing the
levels of the adenine nucleotides ATP, ADP and AMP. Biochemical and

** Host-microbe interaction: Innate immunity cues virulence
Michelle M. C. Buckner and B. Brett Finlay
Salmonella intestinal pathogens employ a clever trick. They use the
immune response that their host triggers to destroy them to enhance
the expression of genes that mediate the pathogens' virulence.
