Cells within the center of a tumor have the highest chance of spreading around the body

Researchers from the Francis Crick Institute, Royal Marsden, UCL and Cruces University Hospital have found that cells from different parts of kidney tumors behave differently, and surprisingly, cells within the center of a tumor are the most aggressive and have the highest chance of spreading around the body.

Combination of Omega-3S in supplements may blunt the cardiovascular benefits of EPA

Doctors often recommend Omega-3s to help patients lower their cholesterol and improve heart health. Those Omega-3s can come from fatty fish like salmon and mackerel, or supplements that often contain a combination of the acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

New probe allows real-time imaging of molecular orientations in live cells

Monitoring alignments of the building blocks of cells is important to understand how the cells are built. By collaborating with imaging scientists at the MBL, researchers from Japan have developed a new probe which they call POLArIS, allowing real-time imaging of molecular orientations in live cells.

Epigenetic changes drive the fate of a B cell

B cells are the immune cells responsible for creating antibodies, and most B cells produce antibodies in response to a pathogen or a vaccine, providing immunity.

Scientists identify the language the body uses to marshal responses to threats

UCLA life scientists have identified six "words" that specific immune cells use to call up immune defense genes -- an important step toward understanding the language the body uses to marshal responses to threats.

Cancer cells re-organize DNA structure to ramp up the activity of oncogenes

A lot of biological mechanisms go wrong in cancer—for example genes mutate and cells proliferate in an uncontrollable manner.

Access to nature increases people's physical activity and their overall health

Your local city park may be improving your health, according to a new paper led by Stanford University researchers. The research, published in Proceedings of the National Academy of Sciences, lays out how access to nature increases people's physical activity - and therefore overall health - in cities.

New method can enable early detection and treatment of cerebral aneurysms

Cerebral aneurysms are malformations caused by abnormalities on the walls of blood vessels in the brain. When these blood vessels rupture, about 30% of the sufferers die on the spot, giving these the rightful label of 'ticking bombs in the head'.

Study: Individuals who recovered from depression had increased level of serotonin transporter

Low levels of serotonin in the brain are seen as a possible cause of depression and many antidepressants act by blocking a protein that transports serotonin away from the nerve cells.

Study unravels the role of proteins in data processing in the brain

For data to travel from one nerve cell to the next, a complex association between different proteins is necessary.

Supercoiling characteristic of DNA's structure controls gene expression, research shows

The two meters of -stretched- DNA contained in human cells are continuously twisting and untwisting to give access to genetic information: when a gene is expressed to generate a protein, the two strands of DNA are separated to give access to all the machinery necessary for this expression, resulting in an excessive accumulation of coiling that needs to be resolved later.
