Focus] Origins: On the Origin of The Immune System
Did the immune system evolve to keep out harmful organisms, or is it
like a bouncer at a nightclub, trained to allow the right microbes in
and kick the less desirable ones out? In the fifth essay in Science's
series in honor of the Year of Darwin, John Travis explores the
evolution of the immune system.

ORIGINAL
ARTICLE: Identification and Importance of Brown Adipose Tissue in Ad...
This study used 18F-fluorodeoxyglucose positron-emission
tomographic
and computed tomographic scans to identify substantial depots of brown
adipose tissue in a region extending from the anterior neck to the
thorax. Such depots were found in 7.5% of the women (76 of 1013) and
3.1% of the men (30 of 959). The amount of brown adipose tissue was
inversely correlated with body-mass index, especially in older people,
suggesting a potential role of brown adipose tissue in adult human
metabolism.
SPECIAL
ARTICLE: Changes in the Incidence and Duration of Periods without Ins...
On the basis of data from U.S. national surveys, the authors
estimate
that losing health insurance was more common in 2001-2004 than in
1983-1986. Between the earlier and the later surveys, people who lost
insurance became more likely to transition to public insurance than to
private insurance, a finding that suggests that the availability of
public insurance programs has become increasingly important for people
who lose their private insurance.
