A thermodynamic history traces temperature's effect on Universe, Earth and humans
A new book by Gino Segrè, a theoretical physicist at the University of Pennsylvania, makes temperature the theme of a journey through science, history and culture, revealing the surprisingly deep ways in which this subtle parameter has shaped humans and their world.

Researchers aim to control treatment-resistant head lice
University of Massachusetts researchers are looking for ways to overcome resistance in mutant strains of head lice that aren't killed by conventional treatments.

Livermore researchers show depth of injected CO2 into the ocean critical
Researchers from the Lawrence Livermore National Laboratory have determined that the depth of an injection of carbon dioxide into the deep ocean is a good predictor of how effective that location is at sequestering carbon away from the atmosphere.

Study finds childhood health is directly related to social class
Study from Johns Hopkins Bloomberg School of Public Health found that children in higher social class groupings have better health than children in lower social classes.

Risk from breast cancer susceptibility gene may be exaggerated in most studies
An analysis of past studies on mutations in the breast cancer susceptibility genes BRCA1 and BRCA2 suggests that estimates of penetrance (or the likelihood that mutation carriers will develop breast cancer during their lifetime) have been exaggerated.

Other highlights in the August 21 issue of JNCI
Other highlights include a look at recent trends in incidence of AIDS-associated cancers, a study examining the impact of pre-puberty growth on breast cancer risk, a study of the effects of adrenomedullin overexpression on the survival of breast cancer cells, and findings supporting the association between a human papillomavirus 58 variant and cervical cancer.

Report focuses on the science and safety of genetically modified crops
A new report from the American Academy of Microbiology (AAM) looks at the case of a bacterium called Bacillus thuringiensis (Bt) and its use in agriculture in a careful examination of what we know--and what we need to know--about transgenic plants.

Genetic diversity necessary for optimal ecosystem functioning, according to UGA research
Though it has long been known by scientists that an ecosystem needs different kinds of plants and animals for optimal functioning, University of Georgia scientists have recently found that the genetic diversity of species within a habitat also affects ecosystem processes.

Researchers pinpoint pain responses in newborns
Dr. Anna Taddio, a researcher at The Hospital for Sick Children (HSC), has found that newborns who experience repeated painful procedures in the first days of life experience more intense pain and learn to anticipate it.

Emory researcher claims stress-induced changes in brain can create psychiatric disorders
Emory University psychiatrist J. Douglas Bremner, M.D., has compiled more than ten years of research, reflection, and observations as a clinical psychiatrist in a book that explains how stress-induced changes in the brain may account for some psychiatric disorders, including Post-traumatic Stress Disorder (PTSD), dissociative disorders, borderline personality disorder, adjustment disorder, depression, and anxiety.
