UCLA investigators reviewed pharmaceutical ads in American medical journals and found that nearly one-third contained no references for medical claims; while the majority of references to published material were available, only a minority of company data-on-file documents were provided upon request; and the majority of original research cited in the ads was funded by or had authors affiliated with the products manufacturer.
In one of the largest studies of its kind, UCLA investigators reviewed pharmaceutical ads in American medical journals to determine what materials are cited in support of medical claims and if those references are available to physicians. Researchers also determined the funding sources of research cited in the ads. The study is published in the Feb. 15 issue of the Canadian Medical Association Journal.
"Previous studies have shown that physicians drug prescribing is influenced by pharmaceutical ads. We wanted to see what documents were being used to substantiate the claims and how accessible these were to physicians who may want to verify the research findings," said lead author Dr. Richelle Cooper, assistant clinical professor, Division of Emergency Medicine, David Geffen School of Medicine at UCLA.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
