Researchers have developed a new non-invasive optical imaging system that promises to improve diagnosis and treatments for dry eye disease. Dry eye, which often causes irritation and blurred vision, occurs when there is ...

Researchers found that aggressive breast cancers store glycogen in very large amounts, offering an explanation of how cells can change their function to evade treatment, grow and spread. Targeting an enzyme involved in t...

For the first time, researchers have captured images of the formation of individual viruses, offering a real-time view into the kinetics of viral assembly. The research provides new insights into how to fight viruses and...

A researcher who is currently doing his post-doctoral training at Stanford University, has successfully invented a novel transfection method to deliver DNA into immune cells with minimal stress on these cells. This new t...

Researchers found that a stable body temperature holds the key to awakening the body's immune response to fight off brain cancer.

Antibiotics are still the most important weapon for combatting bacterial infections. But medical science is running out of ''ammunition'' because of more and more frequently occurring resistances. Research teams have now...

People eat more with friends and family than when dining alone -- a possible throwback to our early ancestors' approach to survival, according to a new study. This phenomenon is known as 'social facilitation'.

Researchers have developed a new way to deliver the DNA-editing tool CRISPR-Cas9 into microorganisms in the lab, providing a way to efficiently launch a targeted attack on specific bacteria.

Multiple sclerosis, an autoimmune disorder, is known to be driven by 'helper' T cells, white blood cells that mount an inflammatory attack on the brain and spinal cord. A new study pinpoints the specific subgroup of help...

Women who reach menopause before the age of 50 have an increased risk of cardiovascular disease, according to researchers.

Research into the molecular phylogeny (evolutionary history) of the HIV-1B virus in Indonesia has succeeded in illuminating the transmission period and routes for three clades (main branches of the virus). This includes ...

A team of biomedical engineers are developing a therapy which shows early indications it can protect neurons and stimulate the regrowth of blood vessels in damaged tissue.

Researchers have developed 3-dimensional human tissue culture models of pediatric and adult brain cancers in a brain-mimicking microenvironment, that includes brain-derived extracellular matrix (ECM) -- the complex netwo...

Deep brain stimulation (DBS) of an area in the brain called the subcallosal cingulate (SCC) provides a robust antidepressant effect that is sustained over a long period of time in patients with treatment-resistant depres...

When it comes to repairing injured tissue, specialized cells in the body known as fibroblasts are called into action. Fibroblasts give rise to healing cells called myofibroblasts, which generally is good in the short ter...

By scanning whole brains of Alzheimer's model mice from an early age, researchers were able to precisely trace the terrible march of amyloid plaques from deep brain structures outward along specific circuits. They also s...
