Taking evolution's temperature: Researchers pinpoint the energy it takes to make a species

... distributed across the planet." One of the novel insights in the paper is the finding that the energy required to produce a new species is a fixed quantity. "These authors are changing evolutionary biology, ecology and biogeography, putting them into a firm and quantitative foundation based on the first pr...

Mayo Clinic researchers discover cancer cells may move via wave stimulation

...er on the Mayo Clinic team. "Our work provides new insights into a novel mechanism by which cells can internalize growth factor information. Understanding this process is the first step toward one day halting it, preventing it or reversing it therapeutically." Why Movement Matters Cell growth and movement a...

Scientists elucidate the kinome of key model organism

...ed by Dr. Janet Smith, this study offers important insights into the evolution of kinases, which are enzymes involved in cell communication pathways. Approximately 2.5% of human genes code for protein kinases, and mutations in many of these genes are at the root of a range of human diseases. Dictyostelium is...

Gene discovery may shed light on kidney disease

Researchers map out networks that determine cell fate

...ifferent kinds of stem cells develop. It provides insights into how to transform stem cells into therapeutically useful cells and suggests possible new treatments for leukemias, in which a persistent mixed lineage seems to drive cancerous proliferation. Although the researchers worked only with blood-formin...

Neuronal cell cultures kept on the straight and narrow

...and Technology (NIST), may enable new, fundamental insights into the behavior of neuronal cells. Culturing particular types of cells in isolation is a basic technique for measuring how they respond to various stimuli, testing new drugs, and similar cell biology tasks. Neuronal cells, which make up the centra...

What's shaped like a pear and has 2 genomes? Check the pond

Study reveals how ADHD drugs work in brain

...o look deeper within the PFC to gain more detailed insights into how ADHD meds act on nerves to enhance cognitive ability. Other researchers who contributed to the study include UW-Madison co-authors David Devilbiss, Matthew Andrzejewski, Ann Kelley, Brooke Schmeichel, Christina Hamilton and Robert Spencer, ...

Unusual mechanism keeps repair protein accurate

... The Journal of Biological Chemistry, provides new insights into how cells repair damaged DNA. "DNA is constantly attacked and damaged by a variety of agents," Suo says. "The body must properly repair that damage, or it can lead to cell death or to cancer, birth defects and other diseases. "There are si...
