There are certainly worse things to have than a high IQ, but when it comes to successful job performance a high level of practical intelligence may be even more important than an abundance of academic intelligence.

Protein Escort Service
One of immunology's long-standing mysteries, concerning the function of all 'master-key' antibodies capable of binding with numerous proteins, may emerge from a Weizmann Institiute of Science study reported the Proceedings of the National Academy of Sciences (PNAS).

The amount of calcium adolescents need to achieve maximum bone growth has been determined for the first time by a research team at Purdue University.

Condemnation May Be Driving Circumcised Women From Health Care
American physicians are right to condemn the practice of female circumcision, but researchers say that physicians' condemnation of the practice may have the unintended effect of driving circumcised women away from the health care they need.

A team of noted researchers at Colorado State University may have discovered why tuberculosis is so difficult to treat.

Evolution Re-Sculpted Animal Limbs By Genetic Switches Once Thought Too Drastic For Survival
Extremely powerful genes that govern the shape of an embryo from the earliest stages of development have been tinkered with by nature over the course of evolution to create the enormously wide range of animal forms, scientists report in the August 14 issue of the journal Nature.

Where Fossils Fear To Tread: Scientists Follow Genes To An Ancient Ancestor
Some 600 or 700 million years ago, before animal life made a sudden evolutionary shift and diverged into nearly all the major animal divisions we know from fossils, primitive animals were inventing the genes that would make it all possible.

New Test Detects The Spread Of Prostate Cancer Cells With Greater Accuracy
A new test is now available for men with prostate cancer to more accurately find cancerous cells that have spread to lymph nodes anywhere in the body.
