In the bustling economy of the cell, little bubbles called vesicles serve as container ships, ferrying cargo to and from the port - the cell membrane. Some of these vesicles, called post-Golgi vesicles, export cargo made by the cell's protein factory. Scientists have long believed that other, similar vesicles handle the reverse function, importing life-supporting nutrients and proteins through an independent process. By using a finely honed type of microscopy to more precisely examine these transactions, new research shows the processes are not as independent as assumed: certain molecules handle cargo moving in both directions.
Wissenschaftler vom Institut für Biomedizinische Technik der ETH Zürich haben eine Nanospritze entwickelt, mit welcher Medikamente, DNA und RNA in eine einzelne Zelle injiziert werden können, ohne diese zu verletzen.
EPA is promulgating further significant new use rules (SNUR) under section 5(a)(2) of the Toxic Substances Control Act (TSCA) for 23 chemical substances which were the subject of premanufacture notices.
Berkeley Lab scientists stunned the world in 2006 when they proved they could accelerate electrons to very high energies (1 GeV, or a billion electron volts) in a distance of centimeters rather than hundreds of meters. Using the same concepts, those scientists plan to take the project to the next level and build a laser-based accelerator capable of zapping electron beams to energies exceeding 10 GeV in a distance of just one meter.
Ken Matsuoka and co-workers at the RIKEN Plant Science Center in Yokohama, Kyushu University in Fukuoka and Niigata University have discovered a subcellular structure in plants that carries proteins and glycans to the correct locations, especially outside of the cell.
An international team, led by Shingo Nagano from the RIKEN SPring-8 Center in Harima and Hiroyasu Onaka from Toyama Prefectural University, has uncovered the vital role of water in the generation of the antitumor drug staurosporine.
In a landmark technical achievement, investigators in the Vanderbilt Center for Structural Biology have used nuclear magnetic resonance (NMR) methods to determine the structure of the largest membrane-spanning protein to date.
Singularity University - the new academic institution with the goal of preparing the next generation of leaders to address "humanity's grand challenges" - today announced the selection of 40 students to represent the inaugural class for the Graduate Summer Program.
A project under way at the U.S. Department of Energy's Savannah River National Laboratory will study how special coatings that mimic structures found in nature can increase the usefulness of solar energy as a vital part of the nation's future energy strategy.
A research team based at The Australian National University has developed a breakthrough approach to generate quantum entanglement, where information is coded in the physical relationship between two objects.
Composite materials such as fiberglass, which take on a mix of properties of their constituent compounds, have been around for decades. Now, an MIT materials scientist is taking composites to the nanoscale, where entirely new properties, not found in any of the original compounds, can emerge.
Nano 2012 is a cooperation program which aims to boost the technological lead and competitive position of the Grenoble area in the changing conditions of the global semiconductor industry and consolidate its leadership position in the development of (32 and 22 nm) CMOS technologies and derivative technologies for system-on-chips.
