Tracking life's first step: Two molecules 'awaken' brand new genome

Within hours after fertilization, a unique genome forms from chromosomes contributed by the egg and sperm. However, this new genome is initially inactive and must be "awakened" to begin the transcription of its DNA and start ...

Fix, not fight: Scientists help plants regenerate after injury

After injury, plants make a trade-off between repairing damaged tissue and ramping up their defenses, according to a new study led by researchers in New York University's Center for Genomics and Systems Biology and published ...

Fatty acids crucial to embryonic development

One classical question in developmental biology is how different tissue types arise in the correct position of the developing embryo. While one signaling pathway that controls this process has been well described, unexpected ...

Imaging the genome: Cataloguing the fundamental processes of life

The team of researchers, led by Dr Rafael Carazo Salas from the Department of Genetics, combined high-resolution 3D confocal microscopy and computer-automated analysis of the images to survey the fission yeast genome with ...

Deciphering the mechanism that determines organ size and shape

A study by IRB Barcelona's Development and Growth Control Laboratory, headed by ICREA researcher Marco Milán, reveals how Dpp and Wg morphogens regulate organ proportions and patterning of the fly wing through independent ...

Stem cell scientists chew on the mysteries of jaw development

Scientists in the USC Stem Cell laboratory of Gage Crump have revealed how key genes guide the development of the jaw in zebrafish. These findings may offer clues for understanding craniofacial anomalies in human patients, ...

Important fertility mechanism discovered

Scientists in Mainz and Aachen have discovered a new mechanism that controls egg cell fertility and that might have future therapeutic potential. It was revealed by Professor Dr. Walter Stöcker of the Institute of Zoology ...

What makes cell division accurate?

As all school-children learn, cells divide using a process called mitosis, which consists of a number of phases during which duplicate copies of the cell's DNA-containing chromosomes are pulled apart and separated into two ...
