Evolution of complexity recreated using "molecular time travel"
January 9, 2012 Much of what living cells do is carried out by “molecular machines” — physical complexes of specialized proteins working together to carry out some biological function. How the minute steps of evolution produced these constructions has long puzzled scientists, and provided a favorite target for creationists.
For those with diabetes, controlling blood pressure is crucial, but not urgent
January 9, 2012 A new study suggests that middle-aged adults recently diagnosed with diabetes and hypertension have time to try to learn how to control their high blood pressure without medications, but not too much time. The consequences of delaying effective hypertension treatment for up to a year were small–a two-day reduction in quality-adjusted life expectancy–according to a study by University of Chicago researchers published online for the Journal of General Internal Medicine .
Experts urge BMI method for calculating weight in kids with eating disorders
January 4, 2012 An exact determination of expected body weight for adolescents based on age, height and gender is critical for diagnosis and management of eating disorders such as anorexia nervosa and bulimia. However, there are no clear guidelines regarding the appropriate method for calculating this weight in children with such disorders.

‘Head-first’ diversity shown to drive vertebrate evolution
December 21, 2011 The history of evolution is periodically marked by explosions in biodiversity, as groups of species try out a wide range of shapes and sizes. With a new analysis of two such adaptive radiations in the fossil record, researchers have discovered that these diversifications proceeded head-first.
A small step for lungfish, a big step for the evolution of walking
December 12, 2011 View video of the African lungfish using its thin pelvic limbs to lift its body off the bottom surface to propel itself forward. The eel-like body and scrawny “limbs” of the African lungfish would appear to make it an unlikely innovator for locomotion.
Molecular markers can predict spread of cancer, guide treatment
December 13, 2011 Molecular markers found in cancer cells that have spread from a primary tumor to a limited number of distant sites can help physicians predict which patients with metastatic cancer will benefit from aggressive, targeted radiation therapy. In a study to be published online Dec.

Tiktaalik discovery among National Geographic’s top grants
December 8, 2011 Neil Shubin’s 2004 discovery of the pivotal fossil Tiktaalik roseae , a transitional species between ancient fish and the first limbed animals, is among 10 projects selected for their historical significance as part of the National Geographic celebration of the magazine’s first 10,000 grants. Since 1890, the National Geographic Society has funded grants to every corner of the planet –unlocking many of its secrets, sometimes in spectacular ways.
Drug combination highly effective for newly diagnosed myeloma patients, study finds
December 6, 2011 A three-drug combination treatment for the blood cancer multiple myeloma compares favorably to the best established therapy for newly diagnosed patients, according to a multi-center study led by Andrzej Jakubowiak, MD, PhD, professor of medicine and director of the multiple myeloma program at the University of Chicago Medical Center. Jakubowiak will present final results of the phase I-II study on Dec.
