Study reveals new and essential details of how photoreceptors work

Moving around in the half-light is difficult but not impossible. To help us in this undertaking we have the rods, a type of light-sensitive cells (photoreceptors) present in the retina of vertebrates, capable of detecting very low lights which allow to move about even in poorly lit cellars or caves.

Neutrophils have more functions in the body than previously thought

Scientists at the Centro Nacional de Investigaciones Cardiovasculares have discovered that neutrophils, the most abundant cells of the innate immune system, have many more functions in the body than previously thought.

Researchers find a new therapeutic approach to combat leukemia

Leukemia frequently originates from the so-called leukemic stem cell, which resides in a tumor promoting and protecting niche within the bone marrow. Scientists from the Max Planck Institute of Biochemistry in Martinsried, Germany, have found a new way to make these cells vulnerable by specifically dislodging these cells from their niches.

Research findings could potentially help exploit the weaknesses of cancer cells

Every cell in our body constantly divides to form new cells. This happens without us even thinking about it. However, every single time a cell divides, a complicated process has to unfold just the right way for our cells to avoid sickness and death.

Study shows how genetic predisposition contributes to the development of multiple sclerosis

About half of the people with multiple sclerosis have the HLA-DR15 gene variant. A study led by the University of Zurich has now shown how this genetic predisposition contributes to the development of the autoimmune disease multiple sclerosis in combination with environmental factors.

Study unravels consequences of mating at the molecular level

While it is known that stem cells have the ability to develop into all tissues in a precisely regulated process, the way environmental cues affect stem cell behavior has remained poorly understood.

Research elucidates molecular mechanism behind learning and memory function

The long-term potentiation (LTP) and long-term depression (LTD) of the strength of hippocampal excitatory synapse involved in learning and memory formation in brain have been separately explained, but the molecular mechanism that comprehensively explains them has not been elucidated.
