---THIS WEEK'S HIGHLIGHTS:

--Earth & Environmental Sciences
-Winter cold of eastern continental boundaries induced by warm ocean
waters
Why are New England winters so chilly? Climate models suggest that
paradoxically, it is a response to the presence of the warm waters
of the Gulf Stream off the North American coast.

--Biological Sciences
-A eudicot from the Early Cretaceous of China
A steady stream of fossil discoveries from the Early Cretaceous of
China is beginning to fill the gaps in our knowledge of the early
history of flowering plants -- and the latest find records a burst
of angiosperm evolution some 125 million years ago.

--Physical Sciences
-Gravity modes as a way to distinguish between hydrogen- and
helium-burning red giant stars
The primary role of NASA's Kepler mission is to discover extrasolar
planets, but here Kepler data are used to distinguish between different
types of red giant star.

** Lessons from the past
The Chernobyl disaster still has much to tell us about the long-term
risks of low-level radiation exposure. But only if the necessary
follow-up studies are supported.

** Concerns over nuclear energy are legitimate
Reassurances from 'experts' on the safety of nuclear power will not wash,
says Colin Macilwain. The Fukushima crisis raises genuine questions.

Jonathan W. Yewdell and Brian P. Dolan
Memory T cells remember viruses from previous infections, providing

they exploit cross-dressing, the transfer of antigens between a
ntigen-presenting cells.

** Molecular genetics: The sound of silence
Laurence D. Hurst
There are various ways in which apparently 'silent' DNA mutations --
those that don't result in a change in the encoded protein -- have
untoward consequences. A striking example has emerged in a study of
Crohn's disease.

Stephen W. Ragsdale
Twenty amino acids form the basis of all proteins, but another two

** Developmental biology: A hair-raising tale
Bruce A. Morgan
Signals from the external microenvironment or 'niche' determine the
fate of stem cells. In the hair follicle, stem cells themselves seem

William R. Boos
Winters are colder in northeastern North America and Asia than in other
