Experts of the state-run corporation Roscosmos started designing a new superheavy rocket on the basis of the “Energia–Buran” program.

The new rocket is said to be built with the use of the existent RD-171 rocket engine. “We do not consider using hydrogen circuits on the first and second stages of this carrier. We intend to take the third stage from the currently-operating Angara rocket,” a representative for the corporation told the Izvestia newspaper.

According to General Director of Rocket and Space Corporation Energia, Vladimir Solntsev, the new rocket will be able to deliver about 80 tons of payload into low support orbit. Its further evolution on the basis of RD-171 engines implies the possibility of increasing the carrying capacity up to 120 tons and, if necessary, to 160 tons. It will be possible to increase the payload by changing the rocket structure and expanding the capacity of the engine.

New methods to counter attack fraud.

“We have introduced the possibility of using blockchain technology to create a seamless and continued global process for the KP certification scheme,” he said.

Blockchain is one of the most significant elements of the revolution in financial technology – fintech – that has been enthusiastically adopted by the UAE. Both Dubai and Abu Dhabi are setting up centres of excellence in fintech.

Mr bin Sulayem has already had meetings with Dubai’s Blockchain Council and is working on a pilot project that would use the technology to monitor KP statistics.

Excellent progress.

The rapid progress that has been sweeping the field of crystal growth and related device technology is opening doors. Perhaps nowhere is the effect of this evolution being felt more than in the development of ultra-small structures whose material properties can be controlled on the nanoscale. The reason for this development: because solid-state nano–structures possess unique optical and electronic properties, they have the potential to be the launching pad of a new generation of devices.

Within the field, researchers are particularly focused on the properties of spins confined within the nano-structures – with the ultimate goal being to use spin nano-systems to develop, for example, robust quantum bits (qubits) capable of storing vast amounts of information. Here, the EU -funded S^3NANO project has successfully developed qubits in a new, innovative form. According to project researchers, these qubits could serve as the information units of the quantum computers of the future.

S^3NANO, which has recently published its full key findings, was a collaborative effort of studies and researchers. It brought together existing studies on the development of new device concepts in the field of few spin solid-state nano-systems with a team of leading international researchers and institutions. Over the course of four years, this ‘few spin solid state nano-system network’ achieved numerous breakthroughs in the understanding and successful utilisation of nanoscale systems in future devices via research, exchange programmes and training sessions.

Watching DNA self-repair itself.

After 2015’s Nobel Prize in chemistry was awarded for advancements in our understanding of DNA repair, a recent Nature report characterises the mechanism in molecular detail. The implications for cancer research are vast.

Researchers in Paris, France, and Bristol, England, have leveraged recent advances in microscopy and fluorescent imaging to characterise the entire process of DNA repair at the molecular level. They were able to observe RNA polymerase, which ‘reads’ DNA and initiates its replication, as it moved along the DNA strand.

When it encountered damage inflicted by UV radiation, the enzyme stalled, and a number of proteins descended on the site. The team followed them as they acted in an ordered step-wise fashion and elucidated the critical steps of the DNA repair process: first, a protein called Mfd coordinates to RNA polymerase, then it directs a sort of relay team of UvrA, UvrB and UvrC. This deeper understanding of the mechanism could bolster efforts towards treatments for a variety of conditions.
