To Focus Better By Considering Symmetry In Microscope

According to a newly discovered property of wave propagation may lead to a novel way to improve the resolution of virtually all optical technologies everything from microscope lenses to telecommunications, laser-based lithography, biological and astronomical imaging. The study was Published in Proceedings of the National Academy of Sciences of the USA (PNAS), this study shows that scientists should re-examine this belief and revisit their design strategies.

Cilia Cells Degenerate And Develop Melanoma

Researchers have now shown that these fine sensory antennae play a key role in the formation of melanoma. Most cells in the human body have a cilium, a slender cell protuberance that picks up signals from the cell's external environment. When cilia are prevented from developing in benign pigment cells, the cells degenerate and develop an aggressive form of melanoma.

Melanomas are one of the most aggressive types of tumors in humans. Despite remarkable success with new forms of treatment such as immunotherapies, there are still many melanoma patients who cannot be cured or who later suffer a recurrence of the disease following successful treatment. An in-depth understanding of the tumor's biology is thus essential for developing novel therapeutic approaches.

New Insights On Brain Activity During General Anesthesia

Researchers have gained new information on brain activity during general anesthesia by recording changes in the electrical activity of the brain. They discovered that changes in electroencephalogram correlated with the loss of consciousness itself and also by the non-specific effects of the drugs. Nearly all participants recalled dreaming during unresponsiveness and, somewhat surprisingly, words presented during anesthesia were still processed in the brain even though the participants were unable to recall them later.

Palliative Care For Seniors With Dementia

A study aims to provide guidance to health care providers as well as government and health system planners, based on recent evidence. Community-based health care providers, such as physicians, nurse practitioners, and others, should be aware of services and resources to help people living at home with dementia as well as their caregivers. The study was published in CMAJ (Canadian Medical Association Journal).
