AUGUSTA, Ga. — The so-called reward center of the brain may need a new name, say scientists who have shown it responds to good and bad experiences. The finding, published in PLoS One, may help explain the “thrill” of thrill-seeking behavior or…
Scientists at Cedars-Sinai Medical Center will work closely with clinicians to develop a new generation of minimally invasive tools and techniques at the hospital’s newly created Minimally Invasive Surgical Technology Institute. The Institute was established through a $1 million grant awarded by the Office of Naval Research in November 2002 and internal contributions from Cedars-Sinai. Under the direction of biophysicist and Fulbright scholar Daniel L. Farkas, Ph.D., the Institute brings together a scientific research group, a pre-clinical facility and a clinical assessment team, all focusing collaboratively on the development, testing and introduction of noninvasive technologies into everyday surgical practice.
In what is a first for biology, a team of investigators is reporting that the human body makes ozone. The team has been slowly gathering evidence over the last few years that the human body produces the reactive gas — most famous as the ultraviolet ray-absorbing component of the ozone layer — as part of a mechanism to protect it from bacteria and fungi. “Ozone was a big surprise,” says researcher Bernard Babior. “But it seems that biological systems manufacture ozone, and that ozone has an effect on those biological systems.”
Using advanced imaging technology and computational simulations, scientists have, for the first time, glimpsed the action of a cellular machine at work within living cells. The work puts forth a new concept of cellular machines as dynamic protein complexes that are continually building and rebuilding themselves within the cell, rather than the stable structures scientists have traditionally thought them to be.
