Scientists studying the humble fruit fly have found a family of proteins that enhances the sensitivity of a cell to a hormone that can trigger abnormal growth and cancer. Their discovery could lead to a completely new approach to tackling some cancers and the development of new drugs to stop uncontrolled growth in a wide variety of tumour cells.
The researchers at the University of Oxford, funded in part by the Biotechnology and Biological Sciences Research Council (BBSRC), discovered that this family of amino acid transporters are very powerful growth promoters. When the transporters were overexpressed in a fly, its cells became hypersensitive to insulin-like molecules in the body that have a long-term role in promoting cell growth and development and the cells grew excessively.
The amino acid transporters appear to be responsive to nutrients on the surface of the cell and do not need to bring these nutrients into the cell. The action of the transporters was so significant that a defect in one of them reduces a fly’s growth by about half.

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
