---THIS WEEK'S HIGHLIGHTS:

--Biological Sciences
-Ultra-prolonged activation of CO2-sensing neurons disorients mosquitoes
The isolation of odorants that modify carbon dioxide detection mechanisms
in the three deadliest mosquito species offers hope that malaria and
dengue fever might be controlled by interfering with insect vectors'
ability to detect a potential host's breath.

--Earth & Environmental Sciences
-A hydrothermal origin for isotopically anomalous cap dolostone cements from south China
Earth's emergence from perhaps its most severe ice age, the Marinoan
'snowball' glaciation some 635 million years ago, is thought to be
linked with a massive release of trapped methane. But now a key line
of evidence for this exit route from a snowball Earth is questioned.

--Physical Sciences
-A graphene-based broadband optical modulator
The development of a graphene-based optical modulator integrated on
a silicon chip opens exciting possibilities for application in the
on-chip optical communications field.

cosmologist suddenly find himself probing the physics of cancer?

** Quantum computing: The power of discord
Physicists have always thought quantum computing is hard because
quantum states are incredibly fragile. But could noise and messiness
actually help things along?

COMMENT
** Children of the AIDS pandemic
Practical support and psychosocial interventions are desperately needed
to help those dealing with the fallout of AIDS, says Lucie Cluver.
http://links.ealert.nature.com/ctt?kn=95&ms=MzY2NzMyNDkS1&r=MjA1NzcwMjE4MQS2&b=2&j=MTAyODgzMTY4S0&mt=1&rt=0

** Stigma impedes AIDS prevention
Medical advances cannot help those who deny they are at risk of HIV and
avoid HIV tests. Salim S. Abdool Karim describes how such attitudes may
be overcome.

Eduardo Reck Miranda is a composer and leading researcher in artificial
intelligence in music, based at the University of Plymouth, UK. A
revised version of his Sacra Conversazione - five movements for
string orchestra, percussion and electronics - will be performed
on 9 June in London. He explains what music can tell us about speech,
physiology and cognition.

Mosquitoes harbouring the malaria parasite follow pulses of carbon

Menno van Lookeren Campagne and Vishva M. Dixit
Humans must maintain a balanced composition for the trillions of

in gut epithelial cells.

Patrick Hayden
Quantum correlations have long been recognized as an informational
resource for quantum communication and computation. It now seems that
they can also do physical work.

Sandra Passchier
The East Antarctic ice sheet, the largest in the world, lies seemingly
frozen in time. Discovery of a rugged landscape buried beneath the
thick ice provides evidence of a more dynamic past.
