Scientists have drawn a connection between the responsiveness to placebo treatment and reward anticipation. In an article published in Nature magazine, scientists from the University of Michigan showed that volunteers who were strongly affected by a placebo treatment showed high ...

Stem cells are at the forefront of medical research and incite some of the most controversial ethical and religious debates worldwide. While regarded by many top scientists as the Holy Grail of medicine, others consider embryonic stem-cell research sacrilegious. Recent ...

Chronic Lymphocytic Leukemia (CLL) is a malignant disease caused by uncontrolled proliferation of B-cells, a type of white blood cells. The high proliferation rate is due to blockage of the cells’ self destruction mechanism called apoptosis, which allows the cells ...

A group of scientists headed by Yoram Palti from the Technion Institute in Israel, succeeded in killing dividing cells without harming non-dividing ones using electrical charges. It turns out that an electrical field in a small enough voltage doesn’t damage ...

What keeps our long term memories viable? Little is known about the way the long term memories are kept in the brain. Does memorizing something new can be compared to writing text on a paper, making it stay forever or ...

Researchers at the University of Arkansas in Fayetteville are testing possible applications of different biosensors – hoping to bring them into use in the health-care industry. The sensors can be applied onto special fabrics with wireless technology, continuously monitoring the ...

Alzheimer’s disease (AD) and some other neuronal disorders, including ALS, are a consequence of massive neuron loss. American scientists have developed a method to decrease neuron loss rate in mice bearing Alzheimer’s disease and ALS analogues. This was achieved by ...
