Bed bugs, once nearly eradicated in the built environment, have made a big comeback recently, especially in urban centers such as New York City. In the first study to explain the failure to control certain bed bug populations, researchers show that some of these nocturnal blood suckers have developed resistance to pyrethroid insecticides
Adolescents who misbehave at school are more likely to have difficulties throughout their adult lives, finds a 40-year study of British citizens published on bmj.com today. These difficulties cover all areas of life, from mental health to domestic and personal relationships to economic deprivation.

In 1913 Theodore Roosevelt added cartographer to his resume when he and his crew ventured up an unspeakably dangerous and uncharted tributary named the River of Doubt. Now, on a charting expedition of their own, Rockefeller University scientists have completed a journey that has also defied expectation.

Masses of immune cells that form as a hallmark of tuberculosis (TB) have long been thought to be the body's way of trying to protect itself by literally walling off the bacteria. But a new study in the January 9th issue of the journal Cell, a Cell Press publication, offers evidence that the TB bacteria actually sends signals that encourage the growth of those organized granuloma structures

Two previously identified pathways associated with aging in mice are connected, say researchers at the Stanford University School of Medicine. The finding reinforces what researchers have recently begun to suspect: that the age-related degeneration of tissues, organs and, yes, even facial skin with which we all struggle is an active, deliberate process rather than a gradual failure of tired cells.

The nuclei of ordinary hydrogen atoms contain only a single proton. If a neutron is added, the hydrogen becomes deuterium. In principle, molecules that contain deuterium in place of hydrogen atoms are chemically identical. However, there can be significant differences.

The evolutionary history of diatoms -- abundant oceanic plankton that remove billions of tons of carbon dioxide from the air each year -- needs to be rewritten, according to a new Cornell study. The findings suggest that after a sudden rise in species numbers, diatoms abruptly declined about 33 million years ago -- trends that coincided with severe global cooling.
