Scientists at the Georgia Institute of Technology have recently developed a miniature sensor that can measure air and water pollution levels. The sensor utilizes polymer membranes deposited on a tiny silicon disk to measure various pollutants present the air and ...
Scientists from the Chonnam National University in Korea have developed a robot that is able to move inside blood vessels. The micro robot has many possible applications, such as performing tests and releasing drugs when hitting a blood clot. The ...
Professor Chang-Jin Kim of the UCLA Henry Samueli School of Engineering and Applied Science has recently invented a microscopic “hand”. Thanks to its tiny 1-millimeter size, the microhand is capable of handling microscopic objects, making it a potentially invaluable tool ...
Researchers from the Hebrew University of Jerusalem discovered a new bacterial communication factor that is associated with bacteria’s death. The intestinal bacteria E. coli activate a “suicide” system in response to stressful conditions and to the density of their population. ...
Researchers from the Max Delbrueck Center for Molecular Medicine (MDC) Berlin-Buch, Germany in collaboration with researchers from the Aarhus University in Denmark have found a receptor responsible for inducing neuronal cell death caused by spinal cord injuries, strokes and aging. ...
Researchers from Cornell University have engineered micro-channels within a water-based gel that can act as a vascular system. The system can carry and deliver oxygen, sugar, proteins, and other growth factors to the growing tissue. The scientists designed the system ...
The Innate immunity system constantly kills cancer cells inside our body. This is one of the reasons not all of us develop cancer. In collaboration between researchers from the Wake Forest University School of Medicine and the Ludwig Institute for ...
An oncologist from Michigan has devised a new approach to clinical medicine. Using DNA micro-array chips, Dr. Eric Lester analyzed gene expression profiles of tumors in patients with advanced incurable cancer. For each patient, he first identified certain genes associated ...
Researchers report that sleep deprivation can double the chances of dying from a cardiovascular event. However, too much sleep appears to be even more dangerous for us, more than doubling the likelihood of dying from other causes. In a research ...
Scientists at Queen’s University in Belfast have developed a novel, more effective way to deliver drugs for the treatment of skin cancer. The scientists demonstrated that a needle-free jet injection of a drug used in the treatment of skin cancer ...
