Evaluating cryptocurrencies

Cryptocurrencies represent a revolutionary monetary system. They are decentralized, essentially unhackable, and represent a novel and disruptive alternative to monetary systems controlled by banks and governments. The value of various cryptocurrencies has waxed and waned, but at the moment one of the more well-known is riding high at a record-breaking valuation. A review in the World Review of Entrepreneurship, Management and Sustainable Development considers the growth, opportunities, and future prospects of cryptocurrencies.

Scientists run a 'speed test' to boost production of carbon nanotubes

Skoltech researchers have investigated the procedure for catalyst delivery used in the most common method of carbon nanotube production, chemical vapor deposition (CVD), offering what they call a "simple and elegant" way to boost productivity and pave the way for cheaper and more accessible nanotube-based technology. The paper was published in the Chemical Engineering Journal.

Molecule that promotes muscle health when magnetised

As people age, they progressively lose muscle mass and strength, and this can lead to frailty and other age-related diseases. As the causes for the decline remain largely unknown, promoting muscle health is an area of great research interest. A recent study led by the researchers from NUS has shown how a molecule found in muscles responds to weak magnetic fields to promote muscle health.

Replicating surfaces, right down to a fraction of an atom

The ability to replicate materials at the atomic level has attracted significant attention from materials scientists. However, the current technology is limited by a number of factors. Udo Schwarz, professor of mechanical engineering & materials science and department chair, has recently published two papers on research that could significantly open up what's possible within this emerging field. His methods include a process that can replicate a surface's features to details of less than one 10 billionth of a meter, or less 1/20th the diameter of an atom.

Biologists summarize 520 studies and report the best way to fertilize soil

A team of biologists from RUDN University working together with foreign colleagues have summarized the results of 520 studies on the impact of manure on the soil and created a snapshot of all biochemical processes that go on in fertilized soils. The team also compared the effect of manure with and without mineral additives, showed how manure from different animals affects the fertility of the soil, and calculated the optimal amount of manure for soil fertilization. The results of the study were published in Science of The Total Environment .

Scientists explain how to store cipher data in magnetic skyrmions

Scientists of Far Eastern Federal University (FEFU) with international collaborators have proposed direct magnetic writing of skyrmions, i.e., magnetic quasiparticles, and skyrmion lattices, within which it is possible to encode, transmit, process information and produce topological patterns with a resolution less than 100 nanometers. This has applications for miniaturized post-silicon electronics, new topological cryptography techniques and green data centers, potentially reducing the load on the Earth's ecosystem significantly. A related article appears in ACS Nano.
