Building artificial nerve cells

Posted by in categories: biological, chemistry, computing, space

For the first time, researchers have demonstrated an artificial organic neuron, a nerve cell, that can be integrated with a living plant and an artificial organic synapse. Both the neuron and the synapse are made from printed organic electrochemical transistors.

On connecting to the carnivorous Venus flytrap, the electrical pulses from the artificial nerve cell can cause the plant’s leaves to close, although no fly has entered the trap. Organic semiconductors can conduct both electrons and ions, thus helping mimic the ion-based mechanism of pulse (action potential) generation in plants. In this case, the small electric pulse of less than 0.6 V can induce action potentials in the plant, which in turn causes the leaves to close.

“We chose the Venus flytrap so we could clearly show how we can steer the biological system with the artificial organic system and get them to communicate in the same language,” says Simone Fabiano, associate professor and principal investigator in organic nanoelectronics at the Laboratory of Organic Electronics, Linköping University, Campus Norrköping.

Inside NASA’s Cold Atom Lab, scientists form bubbles from ultracold gas, shown in pink in this illustration. Lasers, also depicted, are used to cool the atoms, while an atom chip, illustrated in gray, generates magnetic fields to manipulate their shape, in combination with radio waves.

Dead star’s cannibalism of its planetary system is most far-reaching ever witnessed

Posted by in categories: physics, space

The violent death throes of a nearby star so thoroughly disrupted its planetary system that the dead star left behind—known as a white dwarf—is sucking in debris from both the system’s inner and outer reaches, UCLA astronomers and colleagues report today.

This is the first case of cosmic cannibalism in which astronomers have observed a white dwarf consuming both rocky-metallic material, likely from a nearby asteroid, and icy material, presumed to be from a body similar to those found in the Kuiper belt at the fringe of our own solar system.

Sunspot set to burst and fling solar flare ‘directly’ at Earth ‘causing storm’

Posted by in category: space

SPACE weather experts are keeping a close eye on an “enormous sunspot” that’s doubled in size in the past 24 hours.

The unstable patch on the solar surface is directly facing Earth so if it bursts it could fling solar flares our way.

A solar flare isn’t expected to hit yet but it could be possible if the sunspot continues to grow and behave in an unstable manner.
