In quantum computation we use quantum physics to compute. The use of physics in computation raises some deep philosophical problems concerning the relation of math to physics. It concerns the definition of the term ‘computer’ as a physical object. We ...

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 ...

Possibly the first practical model of a time machine proposed by Professor Amos Ori from the Technion Israel Institute of Technology, may prove to be the first step towards a construction of a mechanism that will allow time travel into ...

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 ...

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 ...

The recently released version of the popular software Google Earth includes a new unique feature – a look not down towards our own planet but upwards into the heavens. Clicking the name of your favorite galaxy will take you millions ...

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 ...
