Mathematical method helps to select human embryos

A team of researchers from the University of the Basque Country (UPV-EHU) have developed a mathematical classification which makes it possible to select human embryos for use in assisted reproduction treatments. Scientists have used the morphology of embryos to select the best candidates for implantation in the woman's uterus.

Anthropologist's studies of childbirth bring new focus on women in evolution

Contrary to the TV sitcom where the wife experiencing strong labor pains screams at her husband to stay away from her, women rarely give birth alone.

Researcher presents evolutionary history of modern humans in Africa

Sarah A. Tishkoff, PhD, David and Lyn Silfen University Associate Professor, will present "Evolutionary History of Modern Humans in Africa," at the 2009 American Association for the Advancement of Science (AAAS) annual meeting in Chicago, as a part of the Sunday, February 15th session, "Studying Vertebrate Genomes: Reading Evolution's Notebooks."

Jumping genes play significant role in gene regulatory networks

Research performed in the Center for Biomolecular Science & Engineering (CBSE) at the University of California, Santa Cruz, suggests that mobile repetitive elements--also known as transposons or "jumping genes"--do indeed affect the evolution of gene regulatory networks.

Neural wiring hints at nervous system gene limits

Genetics may play a surprisingly small role in determining the precise wiring of the mammalian nervous system, according to painstaking mapping of every neuron projecting to a small muscle mice use to move their ears.

New insights into human genetic makeup

Genetic diseases and genetically mixed populations can help researchers understand human diversity and human origins according to a Penn State physical anthropologist.

Discovery of gene network that gave rise to first tooth

A paper in this week's PLoS Biology reports that a common gene regulatory circuit controls the development of all dentitions, from the first teeth in the throats of jawless fishes that lived half a billion years ago, to the incisors and molars of modern vertebrates, including you and me.

Xenophobia, for men only

Very few people fear dandelions. Or even dangerous things - like Hummers. We may object to outsized automobiles on principle, but the mere sight of them doesn't make us tremble and sweat and run away. On the other hand, even toddlers show an automatic and powerful fear of snakes, including harmless ones.
