Jacqueline Kim Dale, Ph.D., formerly a Senior Research Associate at the Stowers Institute for Medical Research, and Olivier Pourquié, Ph.D., Stowers Institute Investigator and an investigator with the Howard Hughes Medical Institute, have demonstrated that the long-studied family of transcription factors called Snail is expressed in a cyclic fashion during the formation of the vertebral precursors in the mouse and chick embryo.

Microbiology

Questions around the movement and population size changes of Kiwis, Tuatara and other New Zealand wildlife over the past hundred years have been continually studied by conservationists and scientists. It now seems the answers might all be found in the viruses that infect them.

Molecular & Cell Biology

The same set of genes responsible for establishing the bilateral body axes in animals as diverse as flies and frogs have been found to play an unexpected role in patterning an animal with a different body plan--a simple sea anemone.

Hatchery-reared steelhead trout show increased growth of some parts of the brain when small stones are scattered on the bottom of their tank, according to a new study by researchers at UC Davis. The brains of those young fish were closer to those of salmon reared in the wild, and the fish also showed behavior closer to wild than to hatchery-reared fish.

Australian snakes' venom could provide the next generation of human therapeutic drugs.

A study by researchers at New York University and the University of London offers additional evidence that mammals and fruit flies share a common genetic makeup that determines the function of their internal biological clocks.

This cast of the Triceratops skull shows characteristics — a shortened face and big eyes — that have made babies lovable throughout the ages. The sprouting horns grow to three feet in the adult, while the scalloped edges of the frill, which can grow to seven feet across, become more wavy and develop scales.

With its big, hockey puck-sized eyes, shortened face and nubby horns, it was probably as cute as a button - at least to its mother, a three-horned dinosaur called Triceratops that could weigh as much as 10 tons and had one of the largest skulls of any land animal on the planet.

For neurons, overexcitement is deadly. To avoid this, brain cells must sop up unneeded neurotransmitters from the synapse through membrane-bound transporters. If these transporters fail, neurons and other brain cells get excited to death-- a phenomenon that may contribute to brain damage during stroke and Alzheimer's disease.

Biotechnology

Scientists at The University of Manchester have created a new type of 'bio-gel' which provides a pH neutral environment for culturing cells in 3D, as published in the journal Advanced Materials (March 2006).

The wood shavings from sawmills can be used to produce an organic substrate for use in intensive crop growth in containers. Moreover, this substrate has the advantage that it can be recycled and is more economic than other, imported ones such as peat or coconut fibre.
