Recent research has shown that a drug known as MI-2 can kill cells that cause a fatal brain cancer. But only now have scientists been able to explain how the compound works: by targeting cholesterol production in tumors.

Scientists have discovered microglia actually squeeze through the spinal boundary, crossing into the peripheral nervous system in response to injury.

Scientists have made inroads in integrating electronic sensors with personalized 3D-printed prosthetics.

Researchers have discovered a mechanism by which one type of immune cell, CD8+ T cells, can become dysfunctional, impeding its ability to seek and kill cancer cells.

In the world of racing, the debate on whether women are as fit as men behind the wheel can often become heated. A new study has now demonstrated that women drivers, even with 10 years less experience, react and respond j...

Genes play a role in determining the beauty of a person's face, but that role varies with the person's sex, according to a new study.

Academics have genetically modified yeast cells to help scientists control how they react to their environment in a more desirable way. Yeast was chosen because it shares key characteristics with human cells -- most impo...

Owl monkey cytomegalovirus produces a decoy molecule A43 to evade detection and destruction by immune cells in their hosts, according to a new study. As the authors note, the findings provide a novel example of an immune...

Gut microbes from high HIV-risk men who have sex with men drive immune activation in mice and HIV infection in cells, according to a new study.

An international team of scientists employed an array of next-generation sequencing and gene-editing tools, such as CRISPR, to map the molecular dependencies - and thus vulnerabilities -- of pancreatic cancer stem cells.

Immunotherapy drugs known as checkpoint inhibitors have revolutionized cancer treatment: many patients with malignancies that until recently would have been considered untreatable are experiencing long-term remissions. N...

Insulin triggers genome-wide changes in gene expression via an unexpected mechanism. The insulin receptor is transported from the cell surface to the cell nucleus, where it helps initiate the expression of thousands of g...

Scientists have improved their understanding of a new form of cell-cell communication that is based on extracellular RNA (exRNA) by developing the exRNA Atlas resource, the first detailed catalog of human exRNAs in bodil...

In this study, researchers found evidence that poverty can become embedded across wide swaths of the genome. They discovered that lower socioeconomic status is associated with levels of DNA methylation (DNAm) -- a key ep...

Scientists have developed a method that exploits the multitargeted nature of a chemical inhibitor to pinpoint vulnerabilities within cancer cells.

Parkinson's patients could be helped by fresh insights gained from studies of tiny tropical fish. Research using zebrafish has revealed how key brain cells that are damaged in people with Parkinson's disease can be regen...

Parkinson's is the most common, chronic neurodegenerative movement disorder affecting 1% of the global population over seventy years of age. Right now, there is no cure for this disease and the available treatments focus...

Researchers have identified genetic mutations that accumulate in the adult liver that can promote regeneration in the context of chronic liver damage.

Researchers have discovered a way to better predict progression of Alzheimer's disease. A study utilizing positron emission tomography to image microglial activation levels showed that these levels could predict current ...

Using visualization as motivation is a common technique for achieving goals, but consumers who are pursuing health goals such as eating healthy or losing weight should use caution when using perspective-based visualizati...

Scientists have created a molecule with both strong anti-Zika properties and low toxicity to animal cells.

Renewable energy demand and capacity are growing explosively. When looking at numbers for wind energy production, China stands above all other countries. Figures released by the Global Energy Council in late February sho...
