In plants, steroid levels reflect environmental and internal signals and control many processes. Steroid hormones called brassinosteroids (BRs) start their…
The results indicate remarkable similarity between the gene expression and behavior of the ancient cells that govern reproduction, even between two species…
“These studies show that a potentially protective neutralizing antibody against a viral disease is under the control of immunological tolerance,” said Barton…
In the same journal two other international research teams independently confirm the findings of Dr. John B. Vincent, a scientist at CAMH, and his team. “This…
Recently discovered skull material belonging to the extinct koalas Litokoala and Nimiokoala offers a major step forward in understanding koala evolution,…
Plants take in the carbon dioxide they need for photosynthesis through microscopic breathing pores in the surface of leaves. But for each molecule of the gas…

The new findings provide hope for better treatment for lung diseases like Chronic Obstructive Pulmonary Disease (COPD) and asthma. In the past it has been…
Published today by the leading scientific journal, Proceedings of the National Academy of Sciences (PNAS), the researchers have demonstrated for the first time…
The researchers were studying the gene, called Brd2, which had not previously been linked to body energy balance. While complete absence of the gene was fatal,…
The findings suggest that a better understanding of how the protein, TAK1, works could lead to new insights into the development of liver disease and cancer. “TAK1 appears to be a master regulator of liver function,” said David A. Brenner, MD, professor of medicine and Dean of the UC San Diego School of Medicine. He and Ekihiro Seki, MD, PhD, assistant research scientist in the Department of Medicine, led the work. “Understanding its role in liver disease and cancer may eventually enable us to devise new therapeutic strategies.” Their study appears on line the week of December 14 in advance of publication in the journal Proceedings of the National Academy of Sciences….
