Researchers discover how the heart becomes fully developed

Researchers have discovered how the heart develops from a simple tube into its characteristic S-shape and forms ventricles and atria.

MDC researchers provide new insights on embryonic heart development

When it first starts to develop, the heart is a simple tube. Reporting in the journal Nature Communications, researchers at MDC have now described how it forms itself into a its characteristic S-shape and how the ventricles and atria finally develop.

Researchers report on the sweet side of snake venom toxins

A bite from a lancehead snake can be fatal. Species in the family, found throughout Central and South America, have venom that can disrupt blood clotting and cause hemorrhage, strokes and kidney failure.

Detailed structure of protein pair offers blueprint for new medicines

Walter and Eliza Hall Institute researchers have visualized for the first time how the protein SOCS1 'switches off' cell signaling to dampen immune responses and block cancer growth.

Salk researchers discover molecule that destroys key HIV protein

One of the many challenges in treating HIV is that the virus can lie dormant in cells, quietly evading immune detection until it suddenly roars to life without warning and begins replicating furiously.

Researchers discover three genes that may have contributed to evolution of large human brain

Three genes involved in nerve cell generation in the brain emerged roughly 3.5 million years ago and may have contributed to the rapid evolution of the large human brain, Howard Hughes Medical Institute (HHMI) Investigator David Haussler and colleagues report on May 31, 2018, in the journal Cell.

Scientists uncover the role of the ApoE gene in Alzheimer's Disease

A study conducted at the Massachusetts Institute of Technology has identified why the ApoE4 gene increases the risk of developing Alzheimer's disease, and why the ApoE3 gene reduces the risk.

Weight gain may be the result of inefficient fat metabolism

Researchers from the Karolinska Institutet have shown that protracted weight gain can, in some cases, be attributed to a reduced ability to metabolise fat.

Study shows blood stem cells compensate for immune cell deficiencies

Researchers have shown that if certain blood stem cells that produce immune cells are deficient, other blood stem cells compensate by overproducing the immune cells that are lacking.

Researchers uncover the cause of rheumatoid arthritis

A team of researchers have identified the cellular network involved in initiating and maintaining chronic inflammation in rheumatoid arthritis.

Small defect in tissues can lead normal cells to take on characteristics of diseased cells

Homeowners know that one little termite can lead to big problems: while termites are efficient at gnawing away at wood, they can do even more damage if the wood is already broken or has another defect.

New study shows that epigenetic silencing of genes limits eye development of cave fish

Loss of eye tissue in blind cavefish (Astyanax mexicanus), which occurs within a few days of their development, happens through epigenetic silencing of eye-related genes, according to a study led by the National Institutes of Health. Epigenetic regulation is a process where genes are turned off or on, typically in a reversible or temporary manner.
