Johns Hopkins scientists have identified a protein in fruit flies whose counterpart product in humans may help cause cancer.
The researchers report in the Aug. 12 issue of Cell that a protein dubbed Yorkie directly controls the fruit flys organ size and, when overabundant, causes increased cell growth and decreased cell death, hallmarks of cancer. Yorkies relative in mammals, called YAP, appears to do the same thing, the researchers report, which suggests that in humans, a defect in the gene that makes YAP might contribute to cancer.
"Over the past few decades, science has identified a few so-called oncogenes, whose protein products act as accelerators and trigger abnormal cell growth," said Duojia Pan, Ph.D., who carried out most of the study at the University of Texas Southwestern Medical Center at Dallas before coming to the Johns Hopkins Institute for Basic Biomedical Sciences. "YAP seems to be another one and our lab is already investigating the amount of YAP protein in human tumors to see if excessive amounts are there."

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...
