Missions to the Moon, missions to Mars, robotic explorers to the outer Solar System, a mission to the nearest star, and maybe even a spacecraft to catch up to interstellar objects passing through our system. If you think this sounds like a description of the coming age of space exploration, then you’d be correct! At this moment, there are multiple plans and proposals for missions that will send astronauts and/or probes to all of these destinations to conduct some of the most lucrative scientific research ever performed. Naturally, these mission profiles raise all kinds of challenges, not the least of which is propulsion.

Simply put, humanity is reaching the limits of what conventional (chemical) propulsion can do. To send missions to Mars and other deep space destinations, advanced propulsion technologies are required that offer high acceleration (delta-v), specific impulse (I_sp), and fuel efficiency. In a recent paper, Leiden Professor Florian Neukart proposes how future missions could rely on a novel propulsion concept known as the Magnetic Fusion Plasma Drive (MFPD). This device combines aspects of different propulsion methods to create a system that offers high energy density and fuel efficiency significantly greater than conventional methods.

Florian Neukart is an Assistant Professor with the Leiden Institute of Advanced Computer Science (LIACS) at Leiden University and a Board Member of the Swiss quantum technology developer Terra Quantum AG. The preprint of his paper recently appeared online and is being reviewed for publication in Elsevier. According to Neukart, technologies that can surmount conventional chemical propulsion (CCP) are paramount in the present era of space exploration. In particular, these technologies must offer greater energy efficiency, thrust, and capability for long-duration missions.

In a new Physical Review Letters study, scientists have successfully presented a proof of concept to demonstrate a randomness-free test for quantum correlations and non-projective measurements, offering a groundbreaking alternative to traditional quantum tests that rely on random inputs.

“Quantum correlation” is a fundamental phenomenon in quantum mechanics and one that is central to quantum applications like communication, cryptography, computing, and information processing.

Bell’s inequality, or Bell’s theory, named after physicist John Stewart Bell, is the standard test used to determine the nature of correlation. However, one of the challenges with using Bell’s theorem is the requirement of seed randomness for selecting measurement settings.

According to a new theory presented by researchers at HHMI’s Janelia Research Campus and their colleagues at University College London, how useful a memory is for future situations determines where it resides in the brain.

The theory offers a new way of understanding systems consolidation, a process that transfers certain memories from the hippocampus – where they are initially stored – to the neocortex — where they reside long term.

Under the classical view of systems consolidation, all memories move from the hippocampus to the neocortex over time. But this view doesn’t always hold up; research shows some memories permanently reside in the hippocampus and are never transferred to the neocortex.

The Nobel Physics Prize was awarded on Tuesday to three scientists for their work on attoseconds, which are almost unimaginably short periods of time.

Their work using lasers gives scientists a tool to observe and possibly even manipulate electrons, which could spur breakthroughs in fields such as electronics and chemistry, experts told AFP.

Attoseconds are a billionth of a billionth of a second.

Scientists testing a new method of sequencing single cells have unexpectedly changed our understanding of the rules of genetics.

The genome of a protist has revealed a seemingly unique divergence in the DNA code signaling the end of a gene, suggesting the need for further research to better understand this group of diverse organisms.

Dr. Jamie McGowan, a postdoctoral scientist at the Earlham Institute, analyzed the genome sequence of a microscopic organism—a protist—isolated from a freshwater pond at Oxford University Parks. The research was published in PLoS Genetics.

The use of artificial intelligence has played an important role in science teaching and learning. The purpose of this study was to fill a gap in the current review of research on AI in science education (AISE) in the early stage of education by systematically reviewing existing research in this area. This systematic review examined the trends and research foci of AI in the science of early stages of education. This review study employed a bibliometric analysis and content analysis to examine the characteristics of 76 studies on Artificial Intelligence in Science Education (AISE) indexed in Web of Science and Scopus from 2013 to 2023. The analytical tool CiteSpace was utilized for the analysis.

Astronomers spotted Jupiter-mass binary objects (JUMBOs) in the Orion constellation, and they don’t know how the objects formed.

Contrary to existing antimicrobial coatings, which function by eliminating microorganisms upon contact over some adequate duration of time, the technology developed by FendX takes a preventative approach. Utilizing nanotechnology to develop film and spray protective coatings that prevent microbial adherence to surfaces, thereby minimizing the potential for transmission. This is a significant departure from reactive coating surfaces in the market, offering a proactive method for reducing the occurrence and spread of HAIs.

REPELWRAP™ film, is FendX’s lead product in development and is with their manufacturer who is gearing up to conduct pilot runs on their commercial manufacturing line to create intermediate films for testing. FendX is also developing a spray-based product using their patent-pending nanotechnology. This spray offers the same preventative measures against microbial adherence and has the potential to be more versatile and easier-to-apply to surfaces. It not only demonstrates the same repelling properties but also effectively inactivates any residual microorganisms on the coated surface.

FendX is focused on healthcare settings, but is also exploring potential applications in other multiple billion high-traffic industries. It is anticipated that FendX’s future protective coatings can be applied to various high-touch surfaces: from bed rails and IV poles in healthcare to potential handrails in public transport systems to door handles in restaurants and public bathrooms. Given that the technology inhibits microbial adherence, it has the potential to significantly reduce the spread of pathogens in virtually any setting where human interaction with surfaces occurs. This broad applicability signifies that the market opportunity could be vastly larger than the projected $7.6 billion for antimicrobial coatings by 2025, opening doors to various industries and settings.
