Single embryo transfer as successful as double transfer in older women

Research by fertility experts in Finland has demonstrated for the first time that in many cases transferring a single embryo to the womb in women undergoing IVF is just as likely to result in pregnancy and a live birth in those aged 36 to 39 as it is in younger women.

An evolutionary life-history framework for understanding sex differences in human mortality rates

Despite research efforts to find modern factors that would explain the different life expectancies of men and women, the gap is actually ancient and universal, according to University of Michigan researchers.

Scientists discover structure of malaria defense process

Scientists from two universities in Italy and Virginia Tech in the United States have determined the structure of a protein that is responsible for the production xanthurenic acid (XA) in Anopheles gambiae, the malaria carrying mosquitoes.

Cancer virus protein p13 needed for successful infection and reproduction

New research shows that a protein made by a cancer-causing virus that was thought to be unimportant for its replication is in fact critically needed by the virus to initiate an infection and to reproduce.

Dysregulation of the Hedgehog pathway in human hepatocarcinogenesis

The unchecked activity of a cell signaling pathway crucial in embryonic development and the liver's response to injury leads to liver cancer, researchers from Duke University Medical Center and John Hopkins University School of Medicine have found.

Procedure cures some diabetic mice, but not in the way previously reported

Researchers attempting to reproduce a controversial 2003 mouse experiment suggestive of a cure for type 1 diabetes have found evidence that the experimental procedure does eliminate diabetic symptoms in a small fraction of the mice exposed to it.

Smk-1 is the first known gene that regulates longevity without disrupting life-sustaining function

Within a hormone-triggered cascade of molecular signals that plays a crucial for a wide range of physiological functions, researchers for the very first time have identified a protein that functions specifically to extend lifespan and youthfulness - without disrupting fertility

A map of recent positive selection in the human genome

By scanning the entire human genome in search of genetic variations that may signal recent evolution, University of Chicago researchers found more than 700 genetic variants that may be targets of recent natural positive selection during the past 10,000 years of human evolution.

Nematode hormone discovery may aid fight against parasitic disease

New research at UT Southwestern Medical Center shows that on a biochemical level, hormone-like molecules in tiny worms called nematodes work similarly to the way in which certain hormones work in humans - findings that one day may help eradicate worm infections that afflict a third of the world's population.
