Astrophysicists have discovered that the pulsar wind nebula (PWN) surrounding the famous pulsar B0540-69 brightened gradually after the pulsar experienced a sudden spin-down rate transition (SRT)...

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.

Researchers at the Laboratory of Applied Photonics Devices (LAPD), in EPFL’s School of Engineering, working wi...

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...
