US researchers have uncovered reasons why the Mediterranean diet, with its high intake of oleic acid-rich olive oil, seems to protect against breast cancer. They have also found evidence that oleic acid may have a future role in treatment. The findings are reported today (Monday 10 January) in Annals of Oncology.
The researchers have demonstrated in a series of laboratory experiments on breast cancer cell lines that oleic acid dramatically cuts the levels of an oncogene called Her-2/neu (also known as erb B-2). High levels of Her-2/neu occur in over a fifth of breast cancer patients and are associated with highly aggressive tumours that have a poor prognosis.
Not only did oleic acid suppress over-expression of the gene, other tests on the cell lines showed that it also boosted the effectiveness of trastuzumab (Herceptin), the monoclonal antibody treatment that targets the Her-2/neu gene and has helped to prolong the lives of many breast cancer patients.

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...
Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion
Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...
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...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
