Entering the Graveyard Shift

Information technology conduit as a portal to circumvent the graveyard shift.

I nformation technology (IT) with increasingly faster rates of data transfer is anticipated to continue to shape the practice of medicine in the future. Such changes in health information technology coincide with our rapidly evolving understanding of sleep deprivation and circadian disturbances and their consequent effects on health, performance of the medical provider, and the commission of me...

Buried Alive in the Coronal Graveyard

We have used the High Resolution Camera (HRC-I) of the Chandra X-Ray Observatory to search for coronal (T 106 K) emission from the archetype ‘‘ noncoronal ’’ red giants Arcturus ( Bootis=HD 124897, K1 III) and Aldebaran ( Tauri=HD 29139, K5 III). Our program follows up previous detections of ultraviolet coronal proxies such as C iv 1548 (T 1 105 K) and O vi 1031 (T 3 105 K). The deep ( 19 ks) H...

Cell Death: A One-Way Journey to the Graveyard

Tissue homeostasis is ensured by the correct balance between cell proliferation and death, the latter mainly occurring through a multi-step program, named apoptosis, which ultimately leads to the breakdown of cellular DNA and proteins. Apoptosis is activated under physiological developmental conditions, during metamorphosis and atrophy of tissues and organs, sexual differentiation and cell turn...

Entering the Extranet Era

Combinatorics entering the third millennium

In the later part of the century, attitudes changed. When the 1998 film Good Will Hunting featured a famous mathematician at the Massachusetts Institute of Technology who had won a Fields Medal for combinatorics, many found this somewhat unbelievable.2 However, life followed art in this case when, later in the same year, Fields Medals were awarded to Richard Borcherds and Tim Gowers for work mu...
