Oral cancers are hard to detect in the early stages of the disease because they’re painless or resemble a dental disease. When cancer is detected in the hospital, using sophisticated equipment, it might be too late for the patient. Because ...
Genome of a Single Man Sequenced
Craig Venter, the man who first sequenced the human genome, has now sequenced his own genome. This is the first time a single person’s genome has been sequenced. The genomic sequence can tell a lot about a person, for instance ...
Rewarding Relief
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 ...
Shedding Light on Blindness
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 ...
Blocking the Proliferation of B-cells in Leukemia
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 ...
Killing Cancer Cells Using Electrical Field
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 ...
Keeping Our Memories Fresh
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 ...
Biosphere 2 to Live On
The University of Arizona recently announced that it will be taking on the operation of the Biosphere 2 Project, which was on the verge of being shut down after it ran out of money. This announcement is now giving hope ...
New Biosensors Will Monitor Physiological Signs
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 ...
Long Living Neurons
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 ...
