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 ...

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 ...

The Human Immunodeficiency Virus (HIV) is the cause for the AIDS disease. The virus attacks the T-cells in our blood, an important component of our immune system. The virus penetrates the host by fusing its membrane with the host’s membrane. ...

Most people find needles painful, not to say frightening. Needle-free injections were invented a long time ago, using jet power to insert proteins such as insulin or hormones into the body. However, this method is not commonly used mainly because ...

A team of scientists from the Hebrew University of Jerusalem, headed by Dr. Eran Sharon, managed to harness non–Euclidian geometries in order to develop new structures that can be used in the biomedical and optical industries. The concept might be ...

A new MEMS based scanning technology offers a different possibility for conducting confocal microscopy imaging in confined sections of a living human body. Professor Rebecca Kortum Confocal microscopy is an imaging technique that offers high-resolution imaging of living tissues (in ...

A biosensor developed in Clemson University, South Carolina, funded by the U.S. Department of Defense, will be able to transmit information regarding blood lactate and glucose levels of a wounded soldier or of other injured patients. The biochip will be ...

The resistance of bacteria to antibiotics makes the bacteria increasingly dangerous. Bacteria are capable of changing their genes in a random manner, possibly creating new proteins that are resistant to certain types of antibiotics. The problem worsens when you consider ...
