NASA is partnering with the Defense Advanced Research Projects Agency, or DARPA, to use a nuclear thermal rocket engine in space, according to reports. In a press release on Tuesday, NASA said the nuclear thermal rocket engine could one day be used for NASA crewed missions to Mars. Artist’s concept of the DRACO (Demonstration for …
By depositing atoms on a wafer covered with a “mask” (top left), MIT engineers can group the atoms into the individual pockets of the mask (middle center) and encourage the atoms to grow in layers perfect 2D monocrystalline (bottom right).

Scientists who watched nerve cells connect inside the eyes of growing squid discovered a remarkable secret: the brains of cephalopods evolved independently to develop in the same way as ours. The discovery, made using high-resolution cameras focused on the retinas of longfin squid (Doryteuthis pealeii) embryos, reveals that despite 500 million years of divergent evolution, …

In a recent article published in Natural materialsthe researchers reported an organic electrochemical conductance-based neuron (c-OECN) that mimicked biological signaling in neurons, specifically the activation/inactivation of their sodium and potassium channels. Study: Ion-tunable antiambipolarity in mixed ion-electron conducting polymers enables biorealistic organic electrochemical neurons.

The optical parametric oscillator (OPO) was used in the study. Credit: Alvaro Mountain Warrior Scientists are increasingly studying quantum entanglement, which occurs when two or more systems are created or interact in such a way that the quantum states of some cannot be described independently of the quantum states of others. The systems are correlated, …
