Scientists at The Hospital for Sick Children (Sick Kids) and Yale University School of Medicine have found that a compound in the spice turmeric corrects the cystic fibrosis defect in mice. This research is reported in the April 23, 2004 issue of the journal Science.
Cystic fibrosis (CF) is fatal genetic disease in which thick mucous clogs the lungs and the pancreas due to problems with the secretion of ions and fluid by cells of the airways and gastrointestinal tract. Normal secretion depends upon the function of a protein called CFTR (cystic fibrosis transmembrane conductance regulator), which was discovered at The Hospital for Sick Children in 1989. Mutations in the gene encoding CFTR are responsible for cystic fibrosis. In the most common form of cystic fibrosis, the CFTR protein is trapped inside the cell, and is therefore unable to carry out its proper function at the cell surface.
The laboratories of Drs. Marie Egan, Michael Caplan (both at Yale University School of Medicine), and Gergely Lukacs (Sick Kids) demonstrated in a mouse model that curcumin treatment can release the mutant CFTR protein from this inappropriate compartment inside the cell and allow it to reach its proper destination, where it is able to function. Furthermore, oral curcumin treatment was able to correct characteristic cystic fibrosis defects in a mouse model of the disease. Curcumin is a compound found in turmeric, and is what gives the spice its bright yellow colour and strong taste.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
