When unfolding a tent for the first time, you may wonder how the huge tarpaulin fits into a bag the size of a football. Biologists wonder about something similar: when a cell divides, the surface area of the cell membrane grows. Moreover, when molecules are brought from one organelle to another inside the cell, membrane-enclosed transport vesicles are formed. So that membranes can be made available quickly, they are stored within the cells in the form of nanotubes, tubular membrane structures - similarly to a tarpaulin that has been folded together.
Researchers at The University of Texas at Arlington are perfecting a system to detect a gene mutation implicated in 90 percent of pancreatic cancers and often in lung cancer by running tiny amounts of blood over nanomaterials.
Technology has been developed within Top Institute Pharma that helps medicines be absorbed quicker into the blood and thus be more effective. Researcher Hans de Waard, who is associated with the University of Groningen, will obtain his doctorate on this subject on March 11.
The development of a new measurement technology under a research project funded by the Air Force Office of Scientific Research and the National Science Foundation is probing the structure of composite and biological materials.
Everything moves! But in a world dominated by electronic devices it is easy to forget that all measurements involve motion, whether it is motion of electrons through a transistor, or the simple displacement of a mechanical element. New EU-funded research suggests that quantum mechanics may hold the answer to when motion will die out.
University of Illinois engineers have developed a form of ultra-low-power digital memory that is faster and uses 100 times less energy than similar available memory. The technology could give future portable devices much longer battery life between charges.
Northwestern University researchers have developed a new switching device that takes quantum communication to a new level. The device is a practical step toward creating a network that takes advantage of the mysterious and powerful world of quantum mechanics.
When prostate cancer stem cells were enclosed in self-assembling nanomaterials made of peptides (SAP), the SAP stopped cancer stem cell colony formation and also stopped the division of cancer cells in laboratory cultures (in vitro). According to the international team of researchers who built and tested the nano-sized traps, the cancer cells grew and multiplied after they were "liberated" from their SAP prisons.
Researchers are developing computational models to predict the behaviour of nanomaterials in biological systems. Such predictions will allow researchers to streamline and prioritise the toxicological testing of nanomaterials.
The regions of the world see printed electronics differently. For example, the USA focuses on the military applications among others. East Asia wishes to use printed electronics to reinforce its dominance in electronic displays. Europe has interest in a very wide range of potential applications, with consumer packaged goods being just one of many applicational sectors prioritised.
Physicists have demonstrated an electromechanical circuit in which microwaves communicate with a vibrating mechanical component 1,000 times more vigorously than ever achieved before in similar experiments. This apparatus is a new tool for processing information and potentially could control the motion of a relatively large object at the smallest possible, or quantum, scale.
