Scientists at the Institute of Bioengineering and Nanotechnology (IBN), the world's first bioengineering and nanotechnology research institute, have developed the first injectable hydrogel system with variable stiffness that can control cell proliferation and differentiation in a two-dimensional (2D) and three-dimensional (3D) cell culture environment.
The standard approach to cancer therapy today is to mix and match chemotherapy drugs in order to attack tumors in multiple ways. Now, two separate teams of investigators have demonstrated that using nanoparticles to deliver multiple drugs simultaneously can produce a synergistic effect that boosts the cell-killing ability of both drugs.
Researchers at Rice University, collaborating with investigators at the Baylor College of Medicine, have used two different types of imaging technologies to track the delivery of a therapeutic nanoparticle to breast tumors.
Researchers at the University of Illinois, Urbana-Champaign, have developed a new kind of microsensor to answer one of the weightiest questions in biology - the relationship between cell mass and growth rate.
A porous, disk-shaped "nest" for nanotubes may help magnetic resonance imaging become better than ever at finding evidence of cancer if the results of research led by investigators at Rice University are any indication of future success.
Researchers in Japan have developed a silicon nitride ceramic material which displays significantly higher resistance to thermal shocks and strength at high temperatures than conventional silicon nitride ceramics.
University of Utah physicists stored information for 112 seconds in what may become the world's tiniest computer memory: magnetic 'spins' in the centers or nuclei of atoms. Then the physicists retrieved and read the data electronically - a big step toward using the new kind of memory for both faster conventional and superfast quantum computers.
Physicists from the Max Born Institute in Berlin have now returned to the use of electrons in holography. A special element in their approach is that the electrons that image the object are made from the object itself using a strong laser.
A new method of capturing detailed, three-dimensional images of minute samples of material under extreme pressures is shedding light on the evolution of the Earth's interior. Early results suggest that the early Earth did not have to be entirely molten to separate into the rocky crust and iron-rich core it has today. Researchers at Stanford University and SLAC National Accelerator Laboratory are leading the group pioneering the technique, which could lead to a wide range of new experiments.
In 2009, the journal Nature Physics called it the 'Ionization Surprise'. Where it had been commonly thought that the ionization of atoms by strong laser fields was meanwhile well-understood, novel experiments where rare gas atoms were ionized using relatively long (few-micrometers) wavelength laser light suddenly revealed an unexpected and universal low-energy feature that defied explanation. Now, scientists in Germany provide an explanation.
