Carbon emissions are one of the big concerns impacting climate change, with projects from the development of carbon dioxide-scrubbing plants to businesses pledging to offset their carbon emissions being suggested as ways to reduce our carbon footprint. Now scientists from South Korea have come up with a breakthrough concept which can turn carbon emissions into usable energy.

Scientists from the Ulsan National Institute of Science and Technology (UNIST) developed a system which can continuously produce electrical energy and hydrogen by dissolving carbon dioxide in an aqueous solution. The inspiration came from the fact that much of the carbon dioxide produced by humans is absorbed by the oceans, where it raises the level of acidity in the water. Researchers used this concept to “melt” carbon dioxide in water in order to induce an electrochemical reaction. When acidity rises, the number of protons increases, and these protons attract electrons at a high rate. This can be used to create a battery system where electricity is produced by removing carbon dioxide.

The elements of the battery system are similar to a fuel cell, and include a cathode (sodium metal), a separator (NASICON), and an anode (catalyst). In this case, the catalysts are contained in the water and are connected to the cathode through a lead wire. The reaction begins when carbon dioxide is injected into the water and begins to break down into electricity and hydrogen. Not only is the electricity generated obviously useful, but the produced hydrogen could be used to fuel vehicles as well. The current efficiency of the system is up to 50 percent of the carbon dioxide being converted, which is impressive, although the system only operates on a small scale.

As a mathematical concept, the idea of zero is relatively new in human society—and indisputably revolutionary. It’s allowed humans to develop algebra, calculus and Cartesian coordinates ; questions about its properties continue to incite mathematical debate today. So it may sound unlikely that bees — complex and community-based insects to be sure, but insects nonetheless — seem to have mastered their own numerical concept of nothingness.

Despite their sesame-seed-sized brains, honey bees have proven themselves the prodigies of the insect world. Researcher has found that they can count up to about four, distinguish abstract patterns, and communicate locations with other bees. Now, Australian scientists have found what may be their most impressive cognitive ability yet: “zero processing,” or the ability to conceptualize nothingness as a numerical value that can be compared with more tangible quantities like one and two.

Scientists have developed tiny elastic robots that can change shape depending on their surroundings and can swim through fluids, an advance which may help deliver drugs to diseased tissue one day.

The smart, biocompatible microrobots that are highly flexible are made of hydrogel nanocomposites that contain magnetic nanoparticles allowing them to be controlled via an electromagnetic field.

As a result, these devices are able to swim through fluids and modify their shape when needed. They can also pass through narrow blood vessels and intricate systems without compromising on speed or manoeuvrability, said the group of scientists led by Selman Sakar at Ecole Polytechnique Fédérale de Lausanne (EPFL) and Bradley Nelson at ETH Zurich.

A young mother from Anchorage, Alaska, who was diagnosed with multiple sclerosis (MS) more than 10 years ago says an experimental stem-cell treatment has left her “practically symptom-free.”

Amanda Loy was 27 years old when she was first diagnosed with the disease, which typically affects the brain and spinal cord, also known as the central nervous system. MS can be debilitating and there is currently no cure, according to the Multiple Sclerosis International Federation.

Neuroscientists have for the first time discovered differences between the ‘software’ of humans and monkey brains, using a technique that tracks single neurons.

They found that human brains trade off ‘robustness’ — a measure of how synchronized neuron signals are — for greater efficiency in information processing. The researchers hypothesize that the results might help to explain humans’ unique intelligence, as well as their susceptibility to psychiatric disorders. The findings were published in Cell on 17 January.

Scientists say that this type of unusual study could help them to better translate research in animal models of psychiatric diseases into the clinic.

Now researchers at Ulsan National Institute of Science and Technology (UNIST) in South Korea have made a nanomembrane out of silver nanowires to serve as flexible loudspeakers or microphones. The researchers even went so far as to demonstrate their nanomembrane by making it into a loudspeaker that could be attached to skin and used it to play the final movement of a violin concerto—namely, La Campanella by Niccolo Paganini.

Researchers in South Korea made a tiny loudspeaker, and then used it to play a violin concerto.
