New assay to spot fake malaria drugs could save thousands of lives

New assay to spot fake malaria drugs could save thousands of lives

Chemists and students in science and engineering at Oregon State University have created a new type of chemical test, or assay, that’s inexpensive, simple, and can tell whether or not one of the primary drugs being used to treat malaria is genuine — an enormous and deadly problem in the developing world. The World Health Organization has estimated that about 200,000 lives a year may be lost due to the use of counterfeit anti-malarial drugs Continue reading

Women would benefit from being prescribed exercise as medicine, according to a QUT study that revealed moderate to high intensity activity is essential to reducing the risk of death in older women. Continue reading

No extra mutations in modified stem cells, study finds

No extra mutations in modified stem cells, study finds

The ability to switch out one gene for another in a line of living stem cells has only crossed from science fiction to reality within this decade. As with any new technology, it brings with it both promise–the hope of fixing disease-causing genes in humans, for example–as well as questions and safety concerns. Now, Salk scientists have put one of those concerns to rest: using gene-editing techniques on stem cells doesn’t increase the overall occurrence of mutations in the cells Continue reading

Expectant moms turn to internet for pregnancy advice more than they would like

Expectant moms turn to internet for pregnancy advice more than they would like

Pregnant women are using the Internet to seek answers to their medical questions more often than they would like, say Penn State researchers. “We found that first-time moms were upset that their first prenatal visit did not occur until eight weeks into pregnancy,” said Jennifer L. Kraschnewski, assistant professor of medicine and public health sciences, Penn State College of Medicine Continue reading

Seeing your true colors: Standards for hyperspectral imaging

Seeing your true colors: Standards for hyperspectral imaging

Today, doctors who really want to see if a wound is healing have to do a biopsy or some other invasive technique that, besides injuring an already injured patient, can really only offer information about a small area. But a technology called hyperspectral imaging offers doctors a noninvasive, painless way to discriminate between healthy and diseased tissue and reveal how well damaged tissue is healing over a wide area. The catch Continue reading

Evolution of life’s operating system revealed in detail

The evolution of the ribosome, a large molecular structure found in the cells of all species, has been revealed in unprecedented detail in a new study. Continue reading

Key component of cell division comes to light

Key component of cell division comes to light

The division of a cell in two requires the assembly of the mitotic spindle, an extremely complex structure, which is the result of the coordinated action of a multitude of proteins and a finely tuned balance of their activities. Continue reading

New device could improve biomarker analyses

New device could improve biomarker analyses

A device proposed by researchers at Sweden’s KTH Royal Institute of Technology could offer a more reliable alternative for detecting biomarkers in patients facing such illnesses as cancer or malaria. Whether to extract circulating tumor cells from the blood of a cancer patient, or to measure the elasticity of red blood cells due to malaria infection, the physical attributes of cells are important biomarkers in medicine.
