Researchers at MIT have come up with a de-icing system that is completely passive and relies only on the power of the sun, or artificial light, which means it can also work at night. The system could be used to prevent ice building up on aircraft wings, wind turbine blades, and powerlines.
Rather, they looked like whirlpools in space-time. In the universe, every part of space flowed, churned, trembled between madness and horror like fiery flames that emitted only frost. The Sun and the planets and all substance and existence seemed to be only hallucinations produced by the turbulence of space-time.

The free market Adam Smith Institute says we could be on the cusp of a revolution.
When I wrote that 41% of land in the contiguous United States is used to feed livestock, I thought it was a pretty high number. According to a new report from the free market-leaning Adam Smith Institute, however, the UK has us beat on that front:
Apparently a full 85% of the UK’s land footprint is associated with animal product production.
Space is all the rage, so it seems. The number of small spacecraft – including satellites – being manufactured has rocketed in recent years, and future forecasts are equally explosive. The first-ever internationally agreed requirements have just been published, enabling the industry to cruise even higher.
The small satellites industry is taking off. According to a recent report by SpaceWorks1), an aerospace company focused on delivering cutting-edge flight and space technologies, 2017 showed a 205 % increase in small satellite launches compared to 2016, with a record number still awaiting launch. What’s more, forecasts for future spacecraft production, often by new entrants to the industry, look equally celestial.
But producing these spacecraft involves some very specific requirements that newcomers to the market may not be aware of. To help harmonize the sector, ISO has just published the first-ever international technical specification for small spacecraft, which states the minimum requirements that every small spacecraft needs to comply with regardless of its mission.
The ORC1 gene might not be as indispensable as previously thought in DNA replication.
According to a study conducted by Hollings Cancer Center scientists at the Medical University of South Carolina, DNA replication in murine cells is possible even in the absence of origin recognition complex 1 (ORC1), a protein encoded by the homonymous gene that was previously thought to be indispensable [1].
Study abstract
The largest subunit of the origin recognition complex (ORC1) is essential for assembly of the prereplicative complex, firing of DNA replication origins, and faithful duplication of the genome. Here, we generated knock-in mice with LoxP sites flanking exons encoding the critical ATPase domain of ORC1. Global or tissue-specific ablation of ORC1 function in mouse embryo fibroblasts and fetal and adult diploid tissues blocked DNA replication, cell lineage expansion, and organ development. Remarkably, ORC1 ablation in extraembryonic trophoblasts and hepatocytes, two polyploid cell types in mice, failed to impede genome endoreduplication and organ development and function. Thus, ORC1 in mice is essential for mitotic cell divisions but dispensable for endoreduplication. We propose that DNA replication of mammalian polyploid genomes uses a distinct ORC1-independent mechanism.
A prestigious $20,000 prize has been won by the designer of a futuristic ‘drone ambulance’. Vincenzo Navanteri, 34, from Italy was awarded the Prince Alvaro de Orleans-Borbon Grant, worth $20,000, at the 2nd FAI International Drones Conference and Expo held in Lausanne on 1 September 2018.
He won the grant to help him and his team develop their idea of a self-piloting drone ambulance that could carry a single person for up to 150km at 110km/h.
Collecting the award Navanteri, said: “It is a pleasure to receive this grant, and to use it for development. As a company it is what we need. And, more than my own business, it will support the general development of this type of technology.”
