While the outcomes of this summer's political conventions are predictable, the same cannot be said for the campaigns each candidate will wage this fall.

Northwestern researchers map gene mutation that makes mice deaf and causes them to dance
Northwestern University researchers have mapped the deafness mutation in 'jerker' mice to a gene that encodes for the protein espin.

Chemical signatures in rocks provide clues to origin and evolution of oxygen and terrestrial life on Earth
Scientists analyzing some of the oldest-known rocks on Earth have discovered for the first time a way to recover from the geological record details about the evolution of oxygen and ozone in the planet's early atmosphere--two key ingredients that permitted and recorded the expansion of terrestrial life.

In an effort to provide greater access to current chiropractic research, the Journal of Vertebral Subluxation Research (JVSR), a peer-reviewed scientific journal published by the World Chiropractic Alliance, has converted from a print to an electronic publication.

Gene 'shaving' could help doctors predict the efficacy of cancer treatments
A new statistical method that identifies similar groups of genes from large tissue samples could be used by health care professionals to predict the effectiveness of treating patients suffering from a variety of disorders including cancer, according to a research article published in Genome Biology today.

Quality of relationships can affect health, indicated by level of stress hormones, according to new study
It has been known that unpleasant encounters can evoke strong physiological reactions and can be harmful to one's health if exposed to them over a long period of time.
