A daisy-like plant known as Feverfew or Bachelor’s Button, found in gardens across North America, is the source of an agent that kills human leukemia stem cells like no other single therapy, scientists at the University of Rochester Medical Center’s James P. Wilmot Cancer Center have discovered. Their investigation is reported in the online edition of the journal, Blood.
It will take months before a useable, pharmaceutical compound can be made from parthenolide, the main component in Feverfew. However, UR stem cell expert Craig T. Jordan, Ph.D., and Monica L. Guzman, Ph.D., lead author on the Blood paper, say their group is collaborating with University of Kentucky chemists, who have identified a water-soluble molecule that has the same properties as parthenolide.
The National Cancer Institute has accepted this work into its rapid access program, which aims to move experimental drugs from the laboratory to human clinical trials as quickly as possible. "This research is a very important step in setting the stage for future development of a new therapy for leukemia," says Jordan. "We have proof that we can kill leukemia stem cells with this type of agent, and that is good news." Parthenolide is the first single agent known to act on myeloid leukemia at the stem-cell level, which is significant because current cancer treatments do not strike deep enough to kill mutant cells where the malignancy is born.

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
