Sensational Murders: A Poisonous History of Victorian Society

Working in France in 1903, Augustin Cabanès and Lucien Nass declared, “De toutes les armes que le génie de l’homme a inventées pour nuire à son semblable, le poison est la plus lâche; l’empoisonneur est le plus méprisable des criminels” (1). Although these authors were trying to describe the opinion […]

The Next Step In Cancer Research: Cancer Prevention?

The Next Step In Cancer Research: Cancer Prevention?

In 2006, approximately 1,399,790 new cases of cancer were diagnosed (1). Current treatments and lifestyle changes have significantly improved the fate of these patients; the death rate from the most common cancers—prostrate, breast, lung, and colorectal—and other cancer types is decreasing (1). While the outcome for cancer patients has improved, […]

The Ethical Stem Cell

The Ethical Stem Cell

In November, two teams of scientists published methods of generating embryonic-like stem cells without destroying an embryo, a finding which could quell the ethical controversy surrounding stem cell research. The two independent research teams, headed by James Thomson of the University of Wisconsin-Madison and Shinya Yamanaka of Kyoto University in […]

The Final Countdown

Within one second of the detonation, a 20 pounds per square inch (psi) overpressure will be generated out to a distance of 0.4 miles from the Empire State Building. Everything in this circle is utterly demolished. Those within this circle will be exposed to sudden pressure effects that destroys lungs and ear drums, shrapnel from nearby objects, and a thermal emission of such intensity that immediate death results.

488 nm: A Review of FACS Technology and its Application in Biological Research

488 nm: A Review of FACS Technology and its Application in Biological Research

Fluorescent imaging depends on the physical principles behind the scattering of light. In a typical fluorescent microscope, a laser, usually of argon, shines through a sample at a wavelength of 488 nm. The sample, in turn, fluoresces according to how it was stained. Certain cells, and often even specific cellular structures, can be resolved, which results in a fluorescent image that is reflected into an optical lens or screen for visual analysis.
