Researchers have developed an extremely fast optical method for sculpting complex shapes in stem-cell-laden hydrogels and then vascularizing the resulting tissue. Their groundbreaking technique stands to change the field of tissue engineering.

Tissue engineers create artificial organs and tissues that can be used to develop and test new drugs, repair damaged tissue and even replace entire organs in the human body. However, current fabrication methods limit their ability to produce free-form shapes and achieve high cell viability.

In a new study, researchers at the University of Illinois and the Missouri University of Science and Technology modeled a method to manipulate nanoparticles as an alternative mode of propulsion for tiny spacecraft that require very small levels of thrust.

The team simulated a system that uses light to generate an electromagnetic field. Neutral nanoparticles made from glass or some other material that insulates rather than conducts electric charges are used. The nanoparticles become polarized. All of the positive charges are displaced in the direction of the field and negative charges shift in the opposite direction...

Strong memories are encoded by teams of neurons working together in synchrony. Why is it that you can remember the name of your childhood best friend that you haven’t seen in years yet easily forget the name of a person you just met a moment ago? In other words, why are some memories stable over decades, while others fade within minutes

Using mouse models, Caltech researchers have now determined that strong, stable memories are encoded by “teams” of neurons all fi...

Austrian and Chinese scientists have succeeded in teleporting 3D quantum states for the first time. High-dimensional teleportation could play an important role in future quantum computers.

Researchers from the Austrian Academy of Sciences and the University of Vienna have experimentally demonstrated what was previously only a theoretical possibility. Together with quantum physicists from the University of Science and Technology of China, they have succeeded in teleporting complex high-dimensional quantum states. The research teams report this international first in the journal Physical Review Letters.

In their study, the...
