Study pinpoints mechanism by which spindle checkpoint proteins bind chromosomes

The development of more effective cancer drugs could be a step nearer thanks to the discovery, by scientists at Warwick Medical School, of how an inbuilt 'security check' operates to guarantee cells divide with the correct number of chromosomes.

Scientists discover tumor-targeting neural stem cells

Could engineered human stem cells hold the key to cancer survival? Scientists at the Institute of Bioengineering and Nanotechnology (IBN), the world's first bioengineering and nanotechnology research institute, have discovered that neural stem cells possess the innate ability to target tumor cells outside the central nervous system. This finding, which was demonstrated successfully on breast cancer cells, was recently published in leading peer reviewed journal, Stem Cells.

Researchers uncover 22 new genes linked with autism, other neurodevelopmental disorders

When chromosomes replicate, sometimes there is an exchange of genetic material within a chromosome or between two or more chromosomes without a significant loss of genetic material. This exchange, known as a balanced chromosomal abnormality (BCA), can cause rearrangements in the genetic code.

Study: Your best side may be your left cheek

Your best side may be your left cheek, according to a new study by Kelsey Blackburn and James Schirillo from Wake Forest University in the US. Their work shows that images of the left side of the face are perceived and rated as more pleasant than pictures of the right side of the face, possibly due to the fact that we present a greater intensity of emotion on the left side of our face.

Perivascular fat tissue may influence onset of atherosclerosis

Researchers at UC have confirmed that fat surrounding the outside of arteries in humans-particularly the left coronary artery-may influence the onset of coronary artery disease, or atherosclerosis, which is the leading cause of death in the U.S.

Possibility to render cancer tumours harmless without affecting other cells

New research findings show how it may be possible to render cancer tumours harmless without affecting the other cells and tissues in the body. The findings apply to cancers including breast, lung and bowel cancer. The study was carried out at Lund University in Sweden.

Potential for gallbladder tissue as source for multipotential stem cells

A new study presented today at the International Liver Congress- 2012 indicates the potential for gallbladder tissue (which is routinely discarded from organ donors and surgical interventions) to be a highly available candidate source for multipotential stem cells.

New evidence helps explain additional health benefits of aspirin

New evidence is helping explain additional health benefits of aspirin. Researchers in Canada, Scotland and Australia have discovered that salicylate, the active ingredient in aspirin, directly increases the activity of the protein AMPK (AMP-activated protein kinase), a key player in regulating cell growth and metabolism. AMPK which is considered a cellular fuel-gauge is switched on by exercise and the commonly used anti-diabetic medication metformin.

New technology delivers electrical signals from brain directly to muscles

A new Northwestern Medicine brain-machine technology delivers messages from the brain directly to the muscles -- bypassing the spinal cord -- to enable voluntary and complex movement of a paralyzed hand. The device could eventually be tested on, and perhaps aid, paralyzed patients.
