Medicinal Mimicry
While researchers tease out the mechanisms behind the ability of inert pills and sham procedures to trigger health benefits, the ethics of using such placebos in medical research trials is coming under increasing scrutiny.
- Chemistry
The End of Good Science?
Some chemists are sharing their research results more quickly and broadly as they begin to venture into electronic archives, where they can immediately post new, unreviewed papers, as physicists have done for a decade; others think such archives could mean the end of reliable chemistry research.

A Nation Aflame
In the wake of one of the worst fire seasons in the past 50 years, scientists are assessing risk as more people move into fire-prone areas and developing ways to better predict the behavior of--and the potential for--wildfires.

Errant Texts
New studies lambaste popular middle-school science texts for being uninspiring, superficial, and error-ridden.

Captured on Camera: Are They Planets?
Studying several groups of nearby, newborn stars–many of which weren't known until a few years ago–researchers may soon obtain the first image of a bona fide planet orbiting a star other than our sun.

Dust, the Thermostat
Analyses suggest that dust has profound, complex, and far-reaching effects on the planet's climate.
