Scientists have figured out how to inject a conducting solution into a rose cutting, and have it spontaneously form wires throughout its stem, leaves, and petals to create fully functioning supercapacitors for energy storage.

The so-called e-Plant was able to be charged hundreds of times without any loss on the performance, and the team behind the invention says it could allow us to one day create fuel cells or autonomous energy systems inside living plants.

“A few years ago, we demonstrated that it is possible to create electronic plants, ‘power plants’, but we have now shown that the research has practical applications,” says one of the team, Magnus Berggren from Linköping University in Sweden.

It consists of two thin, flexible polymer films (black) with source, drain, and gate terminals, connected by an electrolyte of salty water that permits ions to cross. A voltage pulse applied to the “presynaptic” layer (top) alters the level of oxidation in the “postsynaptic layer” (bottom), triggering current flow between source and drain.

Stanford University and Sandia National Laboratories researchers have developed an organic artificial synapse based on a new memristor (resistive memory device) design that mimics the way synapses in the brain learn. The new artificial synapse could lead to computers that better recreate the way the human brain processes information. It could also one day directly interface with the human brain.

The new artificial synapse is an electrochemical neuromorphic organic device (dubbed “ENODe”) — a mixed ionic/electronic design that is fundamentally different from existing and other proposed resistive memory devices, which are limited by noise, required high write voltage, and other factors*, the researchers note in a paper published online Feb. 20 in Nature Materials.

A super-material that bends, shapes and focuses sound waves that pass through it has been invented by scientists.

The creation pushes the boundaries of metamaterials — a new class of finely-engineered surfaces that perform nature-defying tasks.

These materials have already shown remarkable results with light manipulation, allowing scientists to create a real-life version of Harry Potter’s invisibility cloak, for example.

British and Czech scientists have unveiled a new “super laser” that they claim is the most powerful pulse laser available today.

The laser was developed by Britain’s Central Laser Facility (CLF) and Czech research and development project HiLASE (high average power pulsed laser). The 22-ton device has been dubbed Bijov after a mythical Czech strongman, and it cost $48 million to build.

Bijov has an average power output of 1,000 watts — a world record for pulse lasers. It first crossed this “magical barrier” on December 16, 2016, and HiLASE physicist Martin Divoky told AFP that it is “10 times as powerful” as any other laser of the same type.

Scientists at Rutgers and other universities have created a new way to identify the state and fate of stem cells earlier than previously possible.

Understanding a stem cell’s fate—the type of cell it will eventually become—and how far along it is in the process of development can help scientists better manipulate cells for stem cell therapy.

The beauty of the method is its simplicity and versatility, said Prabhas V. Moghe, distinguished professor of biomedical engineering and chemical and biochemical engineering at Rutgers and senior author of a study published recently in the journal Scientific Reports. “It will usher in the next wave of studies and findings,” he added.

Researchers announce a potential breakthrough in using nanotechnology to fight cancer.

(Phys.org)—Scientists have found that a superconducting current flows in only one direction through a chiral nanotube, marking the first observation of the effects of chirality on superconductivity. Until now, superconductivity has only been demonstrated in achiral materials, in which the current flows in both directions equally.

The team of researchers, F. Qin et al., from Japan, the US, and Israel, have published a paper on the first observation of chiral superconductivity in a recent issue of Nature Communications.

Chiral superconductivity combines two typically unrelated concepts in a single material: Chiral materials have mirror images that are not identical, similar to how left and right hands are not identical because they cannot be superimposed one on top of the other. And superconducting materials can conduct an electric current with zero resistance at very low temperatures.

Wiring our brains up to computers could have a host of exciting applications – from controlling robotic prosthetics with our minds to restoring sight by feeding camera feeds directly into the vision center of our brains.

Most brain-computer interface research to date has been conducted using electroencephalography (EEG) where electrodes are placed on the scalp to monitor the brain’s electrical activity. Achieving very high quality signals, however, requires a more invasive approach.

Integrating electronics with living tissue is complicated, though. Probes that are directly inserted into the gray matter have been around for decades, but while they are capable of highly accurate recording, the signals tend to degrade rapidly due to the buildup of scar tissue. Electrocorticography (ECoG), which uses electrodes placed beneath the skull but on top of the gray matter, has emerged as a popular compromise, as it achieves higher-accuracy recordings with a lower risk of scar formation.
